Long before JFK and Bill Clinton made headlines, America’s presidents were already dabbling in affairs. The tradition of a side romance is practically a national pastime, right up there with apple pie and fireworks. Welcome to our roundup of the 10 scandalous presidential affairs you’ve probably never heard of.

10 scandalous presidential affairs uncovered

1. FDR And Eleanor Roosevelt

Franklin Roosevelt’s infidelity is fairly well‑known, but his marriage to Eleanor was a tangled web of secrets. The spark began when Lucy Mercer, hired as Eleanor’s social secretary, began an affair with FDR that quickly became the talk of Washington’s elite. Even Alice Longworth, Teddy Roosevelt’s influential daughter, arranged private rendezvous for the couple. When Eleanor uncovered love letters between her husband and Lucy, she demanded a divorce.

FDR was surprisingly open to the idea, even wishing to marry Lucy, who seemed a better match for him than Eleanor. However, his domineering mother threatened to cut off financial support, and his political mentors warned that a divorce would be a career‑killing scandal. Choosing money and ambition over love, FDR begged Eleanor for forgiveness. She agreed to stay, on the condition that he never see Lucy again— a promise he broke— and insisted they no longer share a bed.

The betrayal hit Eleanor hard. Once shy and insecure, she eventually forged a powerful identity outside her husband’s shadow. She found role models in two lesbian couples—Elizabeth Read & Esther Lape and Nancy Cook & Marion Dickerman—who showed her she could thrive independently. Over time, Eleanor transformed into a political force, with Joseph Alsop dubbing her partnership with FDR a “highly successful working partnership” rather than a conventional marriage.

Rumors later swirled about Eleanor’s own romantic entanglements, notably with reporter Lorena Hickock, a woman “sexually oriented to women.” While it’s unclear if Eleanor reciprocated Hickock’s feelings, she certainly adored her, penning affectionate notes like, “I can’t kiss you, so I kiss your picture good night and good morning!” When FDR won the presidency, Eleanor invited Hickock to live in the White House, reassuring her that gossip wouldn’t matter. Meanwhile, FDR maintained his own liaison with his live‑in assistant, Missy LeHand.

Kindree Cushing has never slept with a President.

2. James Buchanan

Before his presidency, James Buchanan was engaged to a wealthy heiress named Anne, who died suddenly just days after their broken engagement. Her family barred Buchanan from attending the funeral, blaming him for her death, and gossip suggested she had been devastated by his infidelity.

Anne’s death wasn’t the only reason Buchanan remained a bachelor. For 23 years he lived with Senator William King, not merely as a roommate but sharing a bedroom. Historians often cite this cohabitation as evidence that Buchanan was America’s first gay president.

Contemporary accounts referred to the pair in colorful terms: a congressman called them “Buchanan and his wife,” while others used nicknames like “Aunt Fancy” and “Siamese twins.” Historian James Loewen noted Buchanan’s openness about the relationship, pointing to surviving letters that reveal deep devotion. In one letter, Buchanan wrote, “I am now solitary and alone… I have gone a wooing to several gentlemen, but have not succeeded with any one of them.”

King’s correspondence echoed this sentiment: “I am selfish enough to hope you will not procure an associate who will cause you to feel no regret at our separation.” Sadly, many of their letters were destroyed by relatives, leaving the true nature of their bond shrouded in mystery.

3. George Washington

In March 1758, a young George Washington visited the newly widowed Martha Custis, the wealthiest woman in Virginia. By January 1759, they were married. Yet, a long‑forgotten letter to his former flame Sally Fairfax resurfaced in 1877, making the front page of the New York Herald.

The letter, penned while George and Martha were formally engaged, began coyly: “I profess myself a votary of love. I acknowledge that a lady is in the case and further I confess that this lady is known to you.” Washington later wrote, “Misconstrue not my meaning; doubt it not nor expose it. The world has no business to know the object of my love declared in this manner to you when I want to conceal it.”

At the time, Sally Fairfax was already married to a close friend of Washington. Her reply was deliberately vague, and the two never spoke of the affair again. In 1775, the British attempted to tarnish Washington with a forged letter alleging an affair with “Kate the washerwoman’s daughter,” but no solid evidence ever proved Washington was unfaithful to Martha after their marriage.

4. Grover Cleveland

Grover Cleveland is one of only three presidents to wed while in office, marrying Frances Folsom in 1886. The match was scandalous: Frances was 27 years younger, and Cleveland had actually bought her baby carriage. Even more controversial, she had been his ward since her father died when she was nine.

But the real shocker lay in Cleveland’s earlier life. In 1873, at age 37, he courted sales clerk Maria Halpin. On December 15, he took her out to dinner and then insisted on escorting her home. Halpin later claimed Cleveland raped her “by use of force and violence and without my consent,” threatening to ruin her if she spoke out. Six weeks later, she discovered she was pregnant.

When the child was born, Cleveland had Maria arrested and committed to an insane asylum, placing the newborn in an orphanage. The asylum’s director recognized the abuse of power and released Maria, noting she had been committed “without warrant or form of law.” The child was never returned to her mother. When the scandal surfaced, Cleveland spread rumors that Halpin was a drunk who had affairs with married men, and suggested the child was actually Oscar Folsom’s. Yet Halpin, a church‑going widow with two children, maintained that Cleveland was the father, a claim supported by Pastor Henry Crabbe, who called Cleveland “a corrupt, licentious man.”

5. Lyndon Johnson

Lady Bird Johnson once quipped, “My husband loved people. He loved all people. Now half the people in the world are women. You don’t think I could keep him away from half the world, do you?” Lyndon and Lady Bird married in November 1934, though they were stark opposites. Lyndon’s explosive ambition often clashed with Lady Bird’s shy, intellectual demeanor.

By 1937, Lyndon began an affair with Alice Glass, the wife of a major political supporter. The relationship persisted into the late 1940s, despite the risk to his career. Lady Bird, noticing Alice’s magnetic presence, blamed herself and responded by becoming more socially active, losing weight, and adopting a flashier wardrobe—while pretending ignorance of the affair.

LBJ wasn’t content with one mistress. He bragged, “I’ve had more women by accident than Kennedy ever had on purpose.” After Lady Bird walked in on him with a secretary in the Oval Office, the Secret Service installed a buzzer to alert him whenever she was nearby.

One of the few women who went public was Madeleine Brown, who claimed a 21‑year affair with LBJ. She alleged that Johnson provided her with a two‑bedroom home, a maid, credit cards, and cars, describing their encounters as “kinky” and typically lasting about thirty minutes.

6. George H.W. Bush

The Washington Post once pointedly noted that political aide Jennifer Fitzgerald had “served President‑elect George Bush in a variety of positions.” Rumors of an affair were “well‑known” among journalists, but nothing was published until 1988, when LA Weekly ran a story claiming Fitzgerald spoke openly about the relationship.

In 1992, the New York Post revived the allegations, and journalist Susan Trento’s book The Power House cited U.S. ambassador Louis Fields arranging a joint guest house for Bush and Fitzgerald during a 1988 Geneva visit. Fields allegedly confessed that “it became very clear to me that the Vice President and Mrs. Fitzgerald were romantically involved.” Trento’s husband delayed reporting the comment at Fields’s request, fearing career damage, but went public after the ambassador’s death.

The story resurfaced when unauthorized biographer Kitty Kelley repeated the claims in her 2004 book The Family. According to Kelley, longtime Republican stalwart James Baker refused to run Bush’s 1980 campaign unless Fitzgerald was removed from the picture.

Unlike most entries here, the Bush allegations remain unproven, and the Bush family has vigorously denied them. When reporter Mary Tillotson asked Bush about the affair at a live news conference, his staff reportedly erupted, vowing she would “never work around the White House again.”

7. James Garfield

While in school, James Garfield was obsessed with sex, homosexuality, and masturbation, even taking cold showers to curb his urges. Though attracted to independent women, he felt compelled to marry the “asexual wallflower” Lucretia “Crete” Rudolph, whom he met while working as a janitor at the Eclectic Institute in Hiram, Ohio. Their engagement in 1854 coincided with Garfield’s affair with the witty Rancie Selleck, a friend who knew his “sensuous” side. Crete was aware of the liaison, calling it the “keenest dagger to my heart,” and the affair lasted until 1858.

In 1862, Garfield pursued an 18‑year‑old New York Tribune reporter, Lucia Gilbert Calhoun. He also maintained a long‑term relationship with Eclectic Institute student Almeda Booth. When Crete confronted him about Booth, Garfield confessed, describing the episode as a “lawless passion.”

Garfield’s womanizing was so prolific that Crete kept herself out of the press, fearing her presence would invite accusations of infidelity. Yet the 1880 election was rocked by rumors that Garfield had visited a New Orleans prostitute.

8. Woodrow Wilson

Woodrow Wilson married artist Ellen Axon in 1885. Their marriage held steady until around 1906, when a series of personal tragedies struck: Ellen’s nephew, his wife, and their two‑year‑old son drowned, while her brother fell into severe depression. Earlier, Ellen’s father had been institutionalized and later committed suicide, adding to the family’s woes. Overwhelmed, Wilson escaped to Bermuda in 1907‑08, where he met Mary Peck.

The friendship with Mary blossomed into a “dalliance,” devastating Ellen and leaving Wilson “guilt‑stricken.” Ellen later said the Peck affair was the only unhappiness her husband ever gave her, while Wilson admitted to a “passage of folly and gross impertinence,” abandoning his “standards of honorable behavior.”

After Ellen’s death in August 1914, Wilson, unable to remain single, began seeing widow Edith Galt in early 1915. Advisors warned that the public would react poorly, and gossip intensified when the Washington Post mistakenly reported that “the President has been entering Edith Bolling Galt regularly.” A popular joke of the era asked, “What did Mrs. Galt do when the President of the United States proposed to her?” Answer: “She fell out of bed.” Despite lingering rumors about Mary Peck, Wilson married Edith later that year and was re‑elected despite the scandal.

9. Warren G. Harding

Usually regarded as a notably weak president, Warren G. Harding prized being liked over strong leadership, a trait that may explain his infamous weakness for women. His most famous liaison was with Carrie Phillips, which began in 1905 while both were married (Harding was actually good friends with Carrie’s husband). Their steamy love letters were opened to the press in 2014.

During the 1920 presidential campaign, the Republican National Committee essentially bribed Carrie and her husband to stay out of sight, sending them on a free Asian tour with $20,000 in cash.

That’s not a bad deal, but several of Harding’s other lovers fared worse. Before his affair with Carrie ended, Harding took up with Nan Britton, a campaign volunteer 30 years his junior. Nan gave birth to a baby girl in 1919; Harding had the Secret Service hand‑deliver child‑support payments. After his death, Nan sued the estate for a trust fund, losing the case, but she later penned a tell‑all, The President’s Daughter, dedicated “to all unwed mothers.” The book scandalized the nation with vivid accounts of wild escapades, including sex in the Oval Office closet.

Harding’s roster of flings also included a Washington Post employee named Miss Allicott and chorus girls Maize Haywood and Blossom Jones. Two other women claimed to have conceived children by Harding (one had a son, another terminated a pregnancy). There was also a “violent” affair during his Senate years with staffer Grace Cross. Harding didn’t bother hiding his affairs, telling a private group of reporters, “It’s a good thing I am not a woman. I would always be pregnant. I can’t say no.”

10. Dwight D. Eisenhower

Dwight D. Eisenhower is celebrated as one of America’s most successful military leaders, serving as Supreme Commander of the Allied invasion of Europe during World War II. The prolonged separations from his wife, Mamie, during the war may have sparked whispers of an affair back in Washington.

Photos often show Ike close to his secretary‑driver Kay Summersby, sometimes standing a little too near. After years of emotional intimacy, the pair allegedly consummated their relationship in spring 1944. According to Summersby, Ike was actually impotent, confessing that marriage had “killed something” in him, forcing her to take the lead and teach him about sex during their trysts.

When the war ended, Ike formally requested General Marshall to relieve him of duty so he could divorce Mamie and marry Kay. An outraged Marshall refused, threatening to ruin Ike’s career should the divorce proceed. Consequently, the affair ended, only surfacing publicly in 1975 when Kay, after Ike’s death, published a book detailing their relationship.

War is hell, but when it comes to rationing, humans have a knack for turning constraints into creativity. Here are 10 creative ways we outsmarted wartime rationing, proving that necessity truly is the mother of invention.

10 Creative Ways to Beat Rationing

10. Inventing The Twinkie

During World War II, bananas became a scarce luxury in both the United States and Britain because they had to be imported. They were a beloved ingredient in everything from English banana sandwiches to American dessert fillings. In England, cooks substituted mashed parsnips for bananas, but American bakers took a more inventive route, which eventually birthed an iconic snack.

The original Twinkie, introduced in 1930, featured a sponge‑cake filled with banana‑cream. By the early 1940s the banana shortage forced manufacturers to ditch the fruit and replace it with vanilla cream. The change was so well‑received that the new version stuck around even after bananas returned, and the mascot Twinkie the Kid made its debut.

Meanwhile, in wartime Britain a single banana could fetch a staggering price—auctioned in London’s Russell Square in 1942 for the modern‑day equivalent of about $125.

9. Liquid Stockings

Nylon stockings, launched in the late 1930s, became a fashion sensation so quickly that May 16, 1940 was celebrated as “Nylon Day.” However, a year later the material was diverted from women’s hosiery to wartime needs like parachutes, cords, and mosquito netting, leaving women without their beloved nylons.

Undeterred, women turned to cosmetics, painting flesh‑colored makeup onto their legs and drawing seam lines with an eyebrow pencil. This trend birthed “liquid stockings” sold under names like Leg Silque and Silktona, and department stores opened “Leg Makeup Bars” offering Leg Sticks, Leg Art, and Stocking Lotion to keep the look alive.

8. Carrots Instead Of Sugar

Sugar was heavily rationed, but carrots were plentiful, prompting Britain’s Ministry of Food to champion the orange root as a versatile substitute. Their mascot, Doctor Carrot, encouraged citizens to replace sugary treats with carrot‑based creations.

The Ministry’s 1941 competition sparked a flood of recipes: carrot treacle, carrot pudding, carrot jam, and even carrot‑water milk substitutes. Children swapped ice‑cream for carrot sticks, and London sweet‑shops advertised toffee‑dipped carrots as a superior alternative to traditional toffee apples. Other inventions included carrot fudge, marmalade, “cartomel custard,” curried carrots, and mock apricot tarts made entirely with carrots.

At the same time, the British government propagated the myth that carrots sharpened night vision, a clever cover for the Royal Air Force’s secret use of radar technology.

7. Whale Meat

Whale meat emerged as a protein source in several nations, but it truly took hold in Japan. By 1947, whale accounted for roughly half of the nation’s meat consumption, becoming a staple in school lunches and shaping post‑war dietary habits.

Research shows older Japanese adults are far more likely to still enjoy whale meat, whereas only about 30‑year‑olds consume it infrequently, and teenagers often have never tried it. Today, roughly 95 % of the Japanese population does not eat whale, a dramatic shift from the post‑war era when it comprised about a quarter of the diet.

Britain also explored whale as a meat alternative, commissioning food testers in the late 1940s. The trials were disastrous; a tester who’d endured famine in occupied North Africa declared that even the hungriest would refuse whale, effectively ending the British experiment.

6. Wrigley’s Gum And Orbit

Chewing gum was a beloved pastime before World II, but the conflict created a severe domestic shortage. Wrigley’s stockpiles were diverted overseas to supply troops, leaving American civilians without their favorite chew.

To fill the gap, Wrigley introduced a wartime‑only brand called Orbit, marketed as the “Good Wartime Chewing Gum.” Though Orbit vanished after the war, the experiment spurred Wrigley to explore new flavors, leading to the brand’s re‑launch in Europe in 1976.

5. Paperback Books

Paper rationing turned the publishing world on its head, giving rise to the modern paperback. Penguin’s affordable, portable editions thrived under strict guidelines that limited word count, margins, and design flourishes, making them ideal for both civilians and soldiers.

The government’s paper quotas forced publishers to adopt simple layouts, avoiding the elaborate covers of hardcovers. This austerity made paperbacks cheap, easy to transport, and perfect for troops in the field, cementing their popularity.

Seeing the success, other publishers jumped on board, establishing the paperback as a dominant format for decades to come.

4. Spam

Spam’s story is intertwined with the Great Depression, wartime rationing, and soldier morale. Launched in the late 1930s, it was hailed as “miracle meat” for its low cost and long shelf‑life. By 1940, it was in roughly 70 % of American homes and shipped in massive quantities to Britain and the Soviet Union under Lend‑Lease.

Its popularity was bolstered by the Hormel Girls—a troupe of singing, dancing saleswomen who toured the nation in white Chevrolets, promoting Spam by day in supermarkets and entertaining audiences by night.

3. The Black Market

Rationing was presented as a patriotic duty, yet many citizens sidestepped the system via a sprawling black market on both sides of the Atlantic. In the United States, the stamp‑and‑point system could be bypassed when grocers accepted cash or exchanged favors for unused stamps, with an estimated 20 % of businesses participating in such schemes.

In Britain, authorities recorded 114 000 prosecutions for black‑market activity. One audacious tactic involved thieves donning Air Raid Precautions wardens’ armbands to commandeer trucks during raids, loading them with goods under the pretense of “safekeeping.” In 1943, a single heist saw five million ration stamps disappear.

2. Vegetarian Sausages

World I left Germany facing a severe meat shortage, prompting Cologne’s mayor to devise a meat‑free sausage— the Kolner Wurst. The idea stemmed from a 1915 decision to slaughter nine million pigs, deemed a drain on food supplies by physiologist Nathan Zuntz.

Mayor Konrad Adenauer responded by crafting a sausage using flour, soy, rice, and barley. While debate persists over whether the product was truly vegetarian or merely low‑meat, it marked a pioneering shift toward plant‑based alternatives in a culture famed for its meat‑centric cuisine.

1. Imitation Makeup

The British government’s “Beauty is Duty” slogan urged women to stay glamorous despite rationing. Early wartime cosmetics came in patriotic shades like Regimental Red, but shortages soon forced companies to sell makeup as refill‑only packs without applicators.

Resourceful women turned to household items: beet‑root juice for lipstick, boot polish for mascara, chalk and margarine for powder and foundation. Extravagant ’40s hairstyles also served as a workaround for the scarcity of hats, with inventive solutions such as pipe‑cleaner barrettes keeping the glamour alive.

Human psychology remains one of science’s most intricate puzzles, trailing only behind the mysteries of cat behavior. In this whirlwind tour of the mind, we’ll chisel away at ten fresh insights that are reshaping what we know about how we think, feel, and act. These 10 amazing new revelations range from diet and language tricks to sleep patterns, misinformation defenses, and even the gut‑brain connection, giving you a toolbox of unexpected ways to understand yourself and others.

Below you’ll find a countdown of the latest breakthroughs, each explained with a blend of humor, hard data, and a dash of awe. Grab a cup of coffee (or tea, or a snack of salmon) and enjoy the ride through the newest corners of cognitive science.

10 Amazing New Insights on the Human Psyche

10 Behaved

Seafood isn’t merely a tasty treat; it appears to be a catalyst for better social conduct among children. Researchers at the University of Bristol examined data from nearly 6,000 participants in the pioneering “Children of the 90s” cohort and discovered that youngsters who regularly ate shrimp, salmon, and other marine fare displayed higher levels of prosocial behavior at ages seven and nine.

The study zeroed in on traits such as friendliness, altruism, and a willingness to share—qualities that help make the world a kinder place. In contrast, the kids who ate the least seafood by age seven tended to exhibit more negative social tendencies overall.

Even more striking, almost every child in the sample fell short of the recommended two portions of fish per week, especially the fattier options like salmon. Seafood supplies essential nutrients—including omega‑3 fatty acids, selenium, and iodine—yet parental concerns about mercury and over‑consumption often lead to fewer servings on the dinner plate.

9 Phrasing Affects How We Feel About Being Alone

Imagine battling loneliness simply by swapping a word. While solitude can wreak havoc on both physical and mental health, the way we label that alone time can shift our emotional response dramatically. In a study of roughly 700 adults and undergraduates, participants who referred to solitary moments as “me‑time” rather than “isolation” reported a noticeably more positive feeling toward the experience.

The researchers found that the “me‑time” framing nudged people to associate the period with self‑care, relaxation, and personal growth. Conversely, labeling the same period as “isolation” invoked connotations of exclusion and loneliness, dampening any potential emotional boost.

Interestingly, those in the “isolation” group were more likely to think about schoolwork, while the “me‑time” cohort reflected on personal development, underscoring how a simple linguistic tweak can steer the mind toward more constructive thoughts.

8 Sleeping Too Much Impairs Various Brain Functions

A recent investigation by UT Health San Antonio, embedded within the long‑standing Framingham Heart Study, examined the cognitive fallout of oversleeping. The analysis covered 1,853 participants free of dementia and stroke, ranging in age from 27 to 85, with an average age of 50.

Findings revealed that logging more hours of sleep—without the counterpart of sleeping too little—correlated with poorer performance on tasks measuring visuospatial abilities, memory, and other cognitive domains. In other words, excessive slumber can blunt problem‑solving, attention, future planning, and impulse control.

The detrimental impact was especially pronounced among individuals reporting depressive symptoms, suggesting that too much sleep may exacerbate cognitive decline in vulnerable populations.

7 REM Sleep Helps Tame Unpleasant Memories

Sleep is more than a nightly reboot; it actively sculpts the way we handle memories. A study from the University of East Anglia compared brain activity between well‑rested participants and those who were sleep‑deprived, focusing on how unpleasant memories intrude into conscious awareness.

While many assume that sleep simply bolsters memory retention, the researchers discovered the opposite: rapid eye movement (REM) sleep, the dreaming phase, appears to facilitate the intentional forgetting of distressing recollections, preventing them from hijacking daily thoughts.

Brain scans showed that REM sleep modulated activity in several memory‑related regions, either amplifying or dampening signals, thereby helping the brain to quarantine unwanted memories.

So the next time you’re tempted to binge‑watch memes late into the night, remember that a solid dose of REM sleep might be your brain’s secret weapon against mental clutter.

6 Psychological Booster Shots Fight Misinformation

Just as vaccines prime the immune system, “psychological booster shots” can fortify the mind against falsehoods. A consortium of researchers across several universities ran five studies involving more than 11,000 participants, testing three distinct cognitive interventions designed to curb susceptibility to misinformation.

The first approach was text‑based: participants read a concise briefing that outlined common tactics used by purveyors of fake news, equipping them with preemptive knowledge.

The second method employed a short video exposing emotional manipulation techniques, while the third strategy turned learning into an interactive game where users crafted their own fictitious stories, sharpening detection skills. Results showed that all three interventions boosted resistance to misinformation, though the effects faded over time. However, periodic “booster” reminders helped reinvigorate the protective effect.

5 An Interesting Norwegian Study on Long COVID

A collaborative effort between Akershus University Hospital and the University of Oslo examined potential neurological sequelae of long COVID in a modest‑sized cohort of 466 young adults aged 12‑25, assessed at six‑month intervals.

Most participants had previously contracted COVID‑19, while a control group of 85 individuals had never been infected. Within the COVID‑positive group, half reported persistent post‑infective symptoms such as concentration difficulties, poorer sleep, memory problems, and chronic pain.

All participants underwent thorough clinical evaluations, including blood work and neurocognitive testing. The investigators found no evidence of brain damage or significant differences in memory, concentration, or sleep quality between the COVID‑positive and control groups.

While the study does not settle the broader debate over long COVID, it underscores the value of objective clinical assessments over self‑reported surveys, and hints that younger, healthier populations may be less vulnerable to lasting neurological harm.

4 Women Talk More Than Men

The age‑old stereotype that women are more loquacious than men finally received a rigorous test. A 2007 University of Arizona study initially suggested parity, reporting that both genders utter roughly 16,000 words per day.

More recent, large‑scale analyses paint a nuanced picture: women, on average, produce about 3,000 more words daily than men—but only within the age bracket of 25 to 64 years. This discrepancy appears tied to child‑rearing responsibilities, as the data were drawn from over 630,000 recordings across 22 studies involving roughly 2,200 participants wearing wearable microphones.

Overall speech volume has declined for everyone, likely due to the rise of digital communication, yet the gender gap persists in the specified age range, highlighting the influence of life‑stage and social roles on verbal output.

3 Falsehoods Take Hold When We’re Tired

Sleep deprivation may be a hidden driver of gullibility. In a two‑part experiment involving more than 1,000 participants, researchers first administered a sleep‑quality questionnaire, then presented an article about the Notre Dame Cathedral fire—some participants also received a conspiratorial claim about a cover‑up.

Those reporting poorer sleep were significantly more likely to endorse the conspiracy, suggesting that fatigue undermines critical evaluation of dubious information.

The follow‑up investigation pinpointed depression, often linked to chronic sleep loss, as the underlying mechanism that fuels conspiratorial thinking, rather than outright paranoia or anger.

2 Gadget Use Linked to Better Mental Health for Older Folks

While some critics warn that digital devices breed unhappiness and cognitive decline, a massive study of over 411,000 adults aged 50 and above paints a different picture. Researchers at the University of Texas discovered that regular engagement with technology—whether browsing, streaming, or video‑chatting—correlates with improved cognitive wellbeing and a lower risk of dementia.

The analysis, which synthesized findings from 57 separate studies, found that tech‑savvy seniors enjoyed mental health benefits comparable to, or even exceeding, those associated with physical exercise and formal education.

These results challenge the myth of “digital dementia” and highlight how the generation that pioneered the internet is now reaping its protective effects against age‑related cognitive decline.

1 Future Fix for Anxiety: Probiotics?

Imagine treating anxiety with a daily dose of friendly bacteria. Duke University researchers have uncovered a link between gut microbes and anxiety‑related behavior, focusing on microbial metabolites called indoles that influence brain regions governing fear and stress.

Their work suggests that a deficiency in certain gut microbes can disrupt neural signaling, amplifying anxiety symptoms. This opens the door to probiotic‑based interventions as a potential alternative to traditional pharmaceuticals, which often carry side‑effects and variable efficacy.

By targeting the gut‑brain axis, scientists hope to develop safer, more accessible treatments for anxiety disorders, potentially revolutionizing mental health care.

Who knows? Future breakthroughs might even identify microbes that sculpt biceps and quads, turning our gut flora into a full‑body performance enhancer.

When you hear the phrase “10 amazing things,” you probably think of glitter and glamour. But diamonds are far more than just dazzling jewelry; they are geological time capsules that hold some of the most astonishing secrets of our planet. From hidden oceans to extraterrestrial carbon, these ten wonders reveal what lies deep beneath the surface.

10 Amazing Things Inside Diamonds

10 Ringwoodite

Scientists have long suspected that a massive ocean exists deep within Earth’s mantle, hidden inside a green mineral known as ringwoodite. This mineral only forms in the transition zone—a narrow band roughly 515 kilometers (320 miles) beneath the surface, sandwiched between the upper and lower mantle.

Ringwoodite cannot survive at the surface because the crushing pressures required for its stability vanish once it’s brought up. While researchers have occasionally captured it in the lab, it swiftly transforms into another phase once the pressure drops. Geochemist Graham Pearson, however, succeeded in preserving ringwoodite in its natural state.

The breakthrough came when a diamond from a Juína, Brazil mine was examined. Pearson and his team hypothesized that a seismic event ferried the mineral to the surface. Interestingly, the discovery was accidental—Pearson was originally dating the diamond when he noticed the unexpected ringwoodite inclusion.

9 Calcium Silicate Perovskite

Paradoxically, silicate perovskite is the most abundant mineral in the Earth, yet it remains one of the rarest to encounter directly. Roughly 38 % of Earth’s volume is believed to consist of this mineral, but because it resides deep within the mantle, no surface samples have ever been collected.

The tide turned when scientists identified a stable specimen lodged inside a diamond excavated just a kilometer (0.6 mi) beneath the Cullinan Mine in South Africa. The mineral in question is calcium silicate perovskite (CaSiO₃), thought to be the fourth‑most common mineral on the planet.

The host diamond is extraordinary, having formed roughly 700 km (435 mi) below the crust under pressures 240,000 times greater than at sea level. Researchers believe the perovskite became entrapped as the diamond crystallized under these extreme conditions.

8 Ice

Earlier speculation about a deep‑Earth ocean suggested that seawater could be dragged down as the crust subducts into the mantle. While the exact size and longevity of this hidden ocean remain uncertain, recent findings have bolstered the hypothesis.

In March 2018, researchers reported the capture of ice crystals within diamonds that formed deep inside the mantle. The ice, termed ice‑VII, is thought to originate from water that migrated downward with the sinking crust, solidifying under extreme pressure.

Ice‑VII only crystallizes between 610 km and 800 km (379 mi–497 mi) beneath the surface, where pressures exceed 24 gigapascals. To date, three such samples have been documented—two from South African mines and one from a Chinese mine.

7 Liquid Metals

Some of the planet’s largest diamonds were forged at depths ranging from 322 km to 805 km (200 mi–500 mi) within the mantle. These colossal gems often encapsulate metallic impurities that offer a glimpse into the mantle’s composition.

Analysis of 53 such diamonds revealed abundant iron and nickel, alongside trace amounts of methane, hydrogen, and garnet. Curiously, oxygen—a presumed major component—was absent, challenging long‑standing assumptions about mantle chemistry.

6 Harzburgitic Inclusions

Harzburgitic inclusions belong to a subset of peridotite rocks, the most common rock type within Earth’s mantle. Their prevalence makes them useful markers for dating diamonds.

A team at Vrije Universiteit Amsterdam examined 26 diamonds containing these inclusions. Nine of the specimens dated back roughly three billion years, a period marked by continental breakup and intense deep‑earth heating.

Remarkably, ten diamonds were determined to be just 1.1 billion years old—a surprising find, as most diamonds are significantly older. Researchers attribute this youthful age to a massive volcanic eruption in present‑day Zimbabwe, which likely supplied the necessary heat to forge these comparatively recent gems.

5 Boron Molecule

While carat weight is a primary driver of a diamond’s price, the stone’s color—often dictated by trace minerals—plays a crucial role as well. Blue diamonds rank as the second rarest colored variety, trailing only the ultra‑scarce red diamonds.

In 2016, the 24.18‑carat Cullinan Dream, a striking blue diamond, fetched over $23 million at auction. Its vivid hue stems from boron, a rare element in the deep Earth. Most boron resides in the oceanic crust, making its presence at mantle depths a geological curiosity.

Scientists propose that dense tectonic plates, when thrust beneath lighter plates, transport boron (along with methane, hydrogen, and seawater) deep into the mantle, where it becomes incorporated into growing diamonds.

4 Kyanite

Occasionally, diamonds emerge with other gemstones encapsulated within them—rubies, for instance, or the lesser‑known kyanite. While kyanite comes in a rainbow of colors, its blue variety commands the highest market value, even though the pure white form is technically rarer.

Unscrupulous sellers sometimes pass off blue kyanite as the more expensive blue sapphire, underscoring the importance of informed appraisal.

3 Mutated Carbon Atoms

Carbon is famous for existing as diamond, graphite, or buckminsterfullerene, but scientists have identified two exotic forms that are even harder than diamond. These super‑hard crystals were predicted theoretically long before they were observed.

The breakthrough came from the Havero meteorite—a ureilite that fell in Finland in 1971. This meteorite type typically harbors both graphite and diamond.

Researchers believe that as the meteorite barreled through Earth’s atmosphere, intense heating transformed some graphite into a mutated carbon structure, yielding the ultra‑hard crystals.

Because the crystals are minuscule, direct hardness measurements proved impossible. However, their resistance to polishing with diamond paste indicated they surpass diamond in hardness.

2 Carbon‑12

In 1983, a team from Curtin University examined 22 diamonds nestled within zircon crystals from the Jack Hills region of Western Australia. Chemical analysis revealed these diamonds were composed almost entirely of carbon‑12, a light isotope typically associated with biological activity.

Radiometric dating placed the diamonds at 4.2 billion years old, while the surrounding zircons formed 4.4 billion years ago. This predates the previously accepted emergence of single‑celled life by roughly 700 million years, suggesting life may have arisen during the Hadean eon.

Given the extreme conditions of early Earth—scorching temperatures, a magma‑filled ocean—some scientists argue the carbon‑12 may have arrived via extraterrestrial delivery, such as meteorites, rather than indigenous biological processes.

1 Ferropericlase

Finding diamonds that formed deep within the mantle is a rarity, yet researchers at the Gemological Institute of America (GIA) have identified a handful containing ferropericlase—a mineral native to the lower mantle.

These ferropericlase‑bearing diamonds are instantly recognizable by their iridescent sheen, which shifts color with the angle of observation, reminiscent of light dancing through a soap bubble. The phenomenon may stem from fluid inclusions or magnesioferrite within the crystal lattice.

Not every ferropericlase inclusion produces a rainbow effect; some diamonds appear as transparent brown. Moreover, the mere presence of ferropericlase does not conclusively prove mantle origin, as such inclusions can also form in silica‑deficient environments nearer the surface.

Comedy series are frequently dismissed as mere light‑hearted fare, and they rarely snag major awards—yet it’s a pity, because the top 10 things we pull from a great sitcom can shift culture one chuckle at a time.

Top 10 Things We Learned From Comedy Shows

10 It’s OK to Be a Woman

I Love Lucy broke new ground in more ways than one. First, it was truly Lucille Ball’s vehicle, while her real‑life husband, Desi Arnaz, who portrayed her on‑screen spouse, remained a supporting act—a rarity in the 1950s. By the late ’50s, Arnaz managed to earn second billing when the series was rebranded as The Lucille Ball‑Desi Arnaz Show, a title that never quite caught on.

When their marriage dissolved in 1962, Ball bought out Arnaz’s share, taking full ownership of the production company—a bold move for a woman at that time. She also became one of the earliest TV personalities to appear while pregnant, though the network forced her to describe it as “expecting” rather than using the word “pregnant,” which was deemed more proper.

The series highlighted a mischievous Lucy getting into slapstick predicaments while her straight‑laced husband tried—and failed—to mold her into the ideal wife. While everyone else sipped wine, Lucy was busy stomping grapes for fun, turning domestic chores into comedic gold.

Sounds far more entertaining than most household routines.

9 It’s OK to Be Gay

Before becoming a household talk‑show name, Ellen Degeneres headlined her own sitcom, Ellen, which enjoyed massive popularity. In 1997, she publicly announced she was gay, and her TV character mirrored that revelation in the same episode.

The disclosure sparked a mixed reaction. The infamous “Puppy Episode,” where Ellen’s character came out, attracted death threats yet also garnered awards. The series was renewed for a fifth season, though each episode now opened with a disclaimer about “Adult Content.”

Although the show was eventually cancelled, it earned widespread praise for paving the way for later series like Will & Grace, which broadened gay representation on television. Ellen’s cultural impact was later honored with the Medal of Freedom presented by President Obama in 2016.

Even after the sitcom’s end, Ellen Degeneres forged a thriving career as one of the world’s most successful talk‑show hosts.

8 It’s OK Not to Have a Life Plan

Friends reshaped many cultural habits. It turned boutique coffee shop visits into a chic activity, coined the phrase “on a break”—fueling endless debates among couples—and popularized the term “pivot.” Most importantly, it reassured viewers that being 30 without a concrete roadmap is perfectly acceptable.

Except for the perpetually academic Ross, each friend dabbled in multiple careers before discovering a passion. The series normalized being broke, unemployed, or holding odd jobs as temporary stepping stones.

None of the gang (aside from Ross) could predict where they’d be five years ahead, and they embraced that uncertainty. Sometimes, all you need is a cozy coffee shop and good company.

In a coffee shop.

7 It’s OK to Be Bored at Work

Work can be mind‑numbingly dull, and The Office masterfully illustrated just how monotonous a typical 9‑to‑5 can feel.

The show’s depiction of tedium was so vivid that viewers imagined staging their own Office Olympics to break the endless stretch of time.

With eight hours to fill and an endless supply of paper balls and coffee mugs, what else is left to do?

Definitely not work.

The Office made it clear that it’s acceptable to feel indifferent about your job—you’re there for the paycheck, not necessarily for team spirit. No one truly enjoys mandatory team‑building activities, except perhaps the eternally enthusiastic Michael Scott.

And that’s perfectly fine, too.

6 It’s OK to Be Neurotic

Seinfeld is repeatedly voted the greatest sitcom ever, a remarkable feat for a series famously billed as a “show about nothing.” Nearly every character displays a distinct brand of neurosis, yet audiences adore them all.

A group of psychiatry students conducted a tongue‑in‑cheek study, concluding that Jerry likely suffers from obsessive‑compulsive tendencies, Kramer may exhibit schizoid traits, George displays extreme ego‑centric behavior, and Elaine, the original “social‑justice‑warrior,” wrestles with anger issues possibly rooted in an alcoholic parent.

Apparently.

Even though the characters occasionally reveal alarming mental‑health quirks, they manage to navigate life just fine, offering reassurance to viewers who see a bit of themselves in these flaws.

And, of course, it’s hilariously entertaining.

10 Hilarious Attempts To Rephrase Controversial Things

5 It’s OK to Be Pretentious

Frasier, a sitcom about two erudite psychiatrists with hobbies ranging from wine‑tasting to opera, might not sound like a recipe for mass appeal. Yet the series thrived for eleven seasons, boasting fierce sibling rivalry, class tensions, and countless Harvard references, ultimately racking up an impressive 37 Primetime Emmys.

Even though Frasier lives with his working‑class ex‑cop father and a British housekeeper of similarly modest means, he never quite embraces the simpler pleasures of life. By the series’ end, both Frasier and Niles remained as pretentious and competitive as they were in season one.

They once tried co‑authoring a book, launching a restaurant, and joining an exclusive wine club—every social event turned into a chance to outshine one another or, better yet, someone else.

Despite these lofty pursuits, the Crane brothers remained endearingly likable and painfully honest.

If only Frasier could secure a lasting romantic relationship.

Fortunately, fans can look forward to new adventures, as Frasier is slated to return to television in a fresh series—date TBD.

4 It’s OK to Be a Nerd

The Big Bang Theory arguably did more than any other sitcom to elevate scientists into cultural icons, despite its cast comprising a socially awkward genius, an anxious intellectual, a self‑aware wannabe cool guy, and an engineer.

Beyond their mutual obsession with superhero costumes, sci‑fi marathons, and improbable chess matches, the series celebrates intelligence. It validates being a nerd, owning a personal spot on the couch, and even the ritual of knocking three times before entering.

The show goes further by employing scientific consultants to ensure accuracy, leading to guest appearances by real‑life luminaries like Stephen Hawking, who featured in a season‑five episode that even bore his name.

Its impact stretched beyond entertainment; classrooms worldwide saw a surge in physics interest, thanks to the show’s ability to make science intriguing, if not outright cool.

3 It’s OK to Be a Dysfunctional Family

Although animated, The Simpsons stands as a classic sitcom chronicling the misadventures of a working‑class American family. Over 32 seasons and nearly 700 episodes, the family has endured virtually every calamity imaginable. The patriarch is lazy, a poor father, and an even worse husband, while the matriarch juggles keeping the household and children afloat—a demanding feat given the kids she’s tasked with raising.

The series also expands beyond the nuclear family, portraying a sprawling community of neighbors, coworkers, churchgoers, politicians, and media personalities. Production efficiencies allow many voice actors to perform multiple roles, while celebrities vie for the honor of being turned into yellow caricatures.

Though you wouldn’t necessarily want the Simpsons as next‑door neighbors—thanks to constant dog barking, saxophone solos, and perpetual shouting—the family has become one of America’s most beloved.

The show birthed a deluge of memes, most famously Homer’s exclamation “D’oh!” and Groundskeeper Willie’s infamous line branding the French as “cheese‑eating surrender monkeys.”

Le ouch!

2 It’s OK for Old Women to Like Sex

In 1985, a sitcom starring four women was already a rarity, but a main cast of four senior ladies was virtually unheard of. The Golden Girls shattered expectations, portraying four friends—each single in her own way—who unabashedly enjoyed sexuality.

The series tackled topics ranging from the joys and pitfalls of sex to broader discussions about gay rights, same‑sex marriage, pornography, and sexually transmitted infections. While some viewers found the portrayal of characters watching porn uncomfortable, the sight of elderly women casually discussing adult films proved surprisingly disarming.

The show also ventured into progressive territory, addressing gay issues and same‑sex marriage with a blend of innocence, curiosity, and irony that softened potentially contentious subjects for a mainstream audience.

Some audiences balked at the notion of seniors viewing explicit content, yet the scene where one character stands up, points at the TV, and declares, “I did that once,” turned the awkwardness into comedic gold.

Until, that is, one of them suddenly stood up, pointed at the TV and said, “I did that once.”

1 It’s OK to Be Silly

When Monty Python’s Flying Circus premiered in 1969, it offered a brand of humor unlike anything seen before. Even today, the series is hailed as the wildest, funniest, and most surreal sketch show ever produced, with just 45 episodes spawning an entire movement of absurdist comedy.

The show inspired astronomers to name seven asteroids after the Pythons, and paleontologists uncovered a dinosaur‑python fossil christened “Montypythonoides Riversleighensis.” Even John Cleese has a woolly lemur bearing his name.

The Oxford English Dictionary defines “Pythonesque” as “resembling the absurdist or surrealist humor of Monty Python.” Beyond celestial and prehistoric tributes, the term has entered everyday language to describe something unwanted or unappealing.

Thank you, Monty Python, for gifting us the iconic Spam sketch.

Top 10 Mandela Effects (Movie And TV Edition!)

Welcome to a whirlwind tour of the ten things we now understand about schizophrenia, thanks to cutting‑edge research from the 2000s onward. Buckle up for a fun, fact‑filled ride that blends brain science with everyday analogies—while keeping the focus keyword front and center.

10 Schizophrenia Is The Result Of Over‑Intense Mental Processing

A frequent myth claims that those with schizophrenia have feeble cognitive abilities, supposedly explaining delusions and fragmented memories. In reality, brain‑imaging studies reveal the opposite: the disorder may stem from hyper‑active, ultra‑focused processing.

Picture the classic “follow my finger” sobriety test you might have tried after a wild Cinco de Mayo. That simple exercise taps into saccadic eye movements—how the brain handles visual shifts. Researchers at UC Davis’s Center for Mind and Brain asked participants to dart their gaze toward a peripheral target while deliberately ignoring a closer, non‑target that could distract them, all while holding a random color in mind.

The hypothesis was that a non‑target matching the remembered color would be especially distracting. The data showed that participants with schizophrenia were dramatically more thrown off by the color match, and they also displayed a pronounced tendency to hyper‑focus on the space surrounding the main target.

These findings bolster the idea that schizophrenia may arise from an abnormally narrow, excessively intense allocation of mental resources, rather than a deficit.

9 Schizophrenia Is Linked With Brain Areas That Process Cannabis

Whenever someone declares that cannabis “kills the brain,” they often ignore the endocannabinoid system (ECS)—a sophisticated network of receptors fine‑tuned for cannabinoids, crucial for mood, memory, and learning.

The ECS isn’t proof that lighting up in a basement makes you a genius, but its discovery has opened doors to understanding how cannabinoids intersect with mental illness. Scientists at Western Ontario’s Department of Anatomy and Cell Biology examined how these receptors relate to schizophrenia.

They found that the medial prefrontal cortex (PFC) and the basolateral amygdala (BLA) are both rich in cannabinoid receptors and pivotal for emotional regulation. In schizophrenia, these regions often show structural and functional disturbances. Moreover, the study highlighted a strong interplay between cannabinoid signaling and dopamine—a neurotransmitter central to both addiction and schizophrenic pathology.

8 Schizophrenics’ Memories Are More Resilient To Long‑Term Substance Abuse

While it’s well‑known that schizophrenia impairs memory, the impact of chronic substance abuse on working memory in this population has been under‑explored. Researchers led by Drs. Jessica A. Wojtalik and Deanna Barch at Washington University set out to fill that gap.

They scanned 37 individuals with schizophrenia (17 with a history of substance abuse, 20 without) and 32 healthy controls (12 with a substance‑use history, 20 without) while participants performed a working‑memory task in an fMRI scanner.

The control group displayed a marked split in neural activation: those with past substance abuse showed heightened activity in memory‑related regions compared to non‑abusers. In contrast, the schizophrenia cohort showed little difference between former substance‑abusers and non‑abusers, indicating that their baseline working‑memory circuitry is less sensitive to the lingering effects of substance use.

Overall, while schizophrenia patients performed worse than controls across the board, the data suggest that long‑term substance abuse may have a relatively muted impact on their core working‑memory function.

7 Schizophrenics Have Trouble Identifying Facial Expressions But Process Them More

Ever meet someone whose name you can’t recall, yet their face feels instantly familiar? That split‑second recognition taps into a complex dance between conscious identification and subconscious processing. In schizophrenia, this dance gets a twist.

Research by Dr. Quintino R. Mano and Dr. Gregory G. Brown examined how individuals with schizophrenia handle facial emotion cues. While patients often struggle to consciously label emotions—making social interactions fraught—they simultaneously exhibit an elevated rate of automatic, implicit processing of those same facial cues.

In other words, the brain of a person with schizophrenia may be silently cataloguing emotional information even when the conscious mind can’t name it, highlighting a fascinating dissociation between explicit recognition and implicit perception.

6 Siblings Of Schizophrenics Have Different Brain Activity Than Others

Dr. Alan Ceaser and his team investigated whether the neuro‑biological signatures of schizophrenia extend to close relatives. Participants fell into three groups: diagnosed patients, their unaffected siblings, and a healthy control group with no familial link.

The study revealed that both patients and their siblings displayed atypical neural responses to shifts in dopamine availability—unlike the control group. Specifically, abnormal spikes were observed in the dorsolateral prefrontal cortex (DLPFC), cerebellum, and striatum across both the patient and sibling cohorts.

These findings suggest that certain dopaminergic vulnerabilities may be heritable, marking siblings as a population with subtle yet measurable brain‑activity differences that could signal heightened risk.

5 Male Schizophrenic Smokers Are More Susceptible To Nicotine Withdrawal

The cognitive fallout of nicotine withdrawal isn’t confined to the general population; it uniquely impacts male smokers with schizophrenia. Researchers at Tabriz University’s Clinical Psychiatry Research Center examined this phenomenon.

Forty‑five male participants with schizophrenia were divided into three groups: one abstained from smoking overnight, a second abstained but received a nicotine patch, and a third continued smoking freely. All participants completed a visuospatial memory test before the night and again the next morning.

The patch‑treated and unrestricted‑smoking groups showed no meaningful change in performance. However, the group forced to abstain without nicotine support suffered a noticeable decline in visuospatial scores, highlighting that nicotine withdrawal can exacerbate subtle cognitive deficits in this demographic.

4 Gender Affects Schizophrenia Symptoms

Gender isn’t just a demographic label; it shapes how schizophrenia manifests, especially regarding visual‑perceptual organization. Dr. Jamie Joseph and colleagues at Rutgers University probed this angle using two specialized tasks: the Contour Integration Task (bottom‑up grouping) and the Ebbinghaus Illusion (top‑down grouping).

Among 109 participants (43 females, 66 males), females displayed stronger bottom‑up grouping abilities, outperforming males on the Contour Integration Task. Conversely, males excelled on the Ebbinghaus Illusion, indicating superior top‑down processing.

These results underscore that sex‑based neurocognitive differences influence the pattern and severity of schizophrenic symptoms, suggesting tailored therapeutic approaches may be beneficial.

3 Younger Schizophrenics Aren’t Being Treated As Effectively

Despite advances in psychiatric care, age appears to dictate treatment quality. A 2013 analysis published in the Canadian Journal of Psychiatry examined administrative data from Quebec’s adult schizophrenia population over two years.

The study uncovered a stark disparity: 77 % of patients aged 30 + received adequate pharmacological treatment, while only 47 % of those aged 18‑29 did. This gap suggests that younger adults—often in the early stages of the disorder—are less likely to receive optimal medication management.

Given that early, effective intervention is crucial for long‑term outcomes, these findings raise concerns about systemic gaps that leave younger patients underserved.

2 Schizophrenics Have Lower Sex Drive

In 2014, a team at the Clinic for Young Schizophrenics examined psychosexual patterns among 45 young adults with schizophrenia, comparing them to 61 healthy controls.

The results revealed a lower prevalence of sexual partners and fewer instances of ever having intercourse among the schizophrenia group. Moreover, men on antipsychotics such as risperidone or olanzapine reported greater difficulties with arousal than their control counterparts.

While the data debunk the stereotype that mental illness equates to hyper‑sexuality, they also highlight that schizophrenia—particularly when treated with certain medications—can dampen sexual desire and function.

1 Schizophrenia Is Related To Low Appetite Control

A 2012 investigation by the University of Montreal’s psychiatry department explored appetite regulation in individuals with schizophrenia versus healthy controls. Researchers measured brain responses to food cues and examined how antipsychotic dosage influenced cravings.

Only the schizophrenia cohort displayed distinct activation in the parahippocampus, thalamus, and middle frontal gyri when presented with appetite‑stimulating images. Their parahippocampal activity—and self‑reported hunger—rose linearly over time.

Furthermore, higher antipsychotic doses correlated positively with increased cravings, while greater disease severity linked negatively with dietary restraint. In short, schizophrenia appears to impair appetite control, and the medications used to treat it can exacerbate those metabolic challenges.

Ready to dive deeper into the science? Keep exploring, stay curious, and remember that every new discovery brings us closer to better understanding and support for those living with schizophrenia.

Mice are the unsung heroes of biomedical research – tiny, fast‑breeding, and surprisingly adaptable. Over the past few decades, scientists have taken ten notorious human ailments and coaxed them into living, breathing mouse models, giving us a front‑row seat to the inner workings of each disease. This “10 human diseases” tour shows how clever tricks like hormone boosts, gene swaps, and even tiny human tissue grafts can make a mouse act like a miniature version of us.

Understanding 10 Human Diseases Through Mice

10 Gonorrhea

Gonorrhea, the classic sexually transmitted infection caused by the bacterium Neisseria gonorrhoeae, naturally infects only humans. Early attempts to study it in the lab involved simply squirting the bug straight into the vaginas of lab mice, but the bacteria just didn’t feel at home – infection rates were abysmal.

After many false starts, researchers discovered a fleeting window during the mouse estrus cycle when the vaginal environment momentarily mimics that of a human. During this narrow period, N. gonorrhoeae can actually take hold and multiply.

To stretch that golden window, scientists give the mice a dose of the female hormone 17β‑estradiol. The extra estrogen keeps the vaginal conditions favorable for days, allowing the bacteria to thrive for an extended period.

Armed with these hormonally‑treated mice, researchers have been able to trial new antibiotics and probe why a single bout of gonorrhea rarely grants lasting immunity – a puzzling phenomenon that mirrors human experience.

In real‑world settings, gonorrhea rarely flies solo; about 70 % of infections accompany chlamydia. To explore this co‑infection, scientists have engineered “double‑STD” mice by sequentially injecting two bacteria – C. muridarum followed by N. gonorrhoeae – into the same animal, recreating the complex microbial dance seen in patients.

9 Alzheimer’s Disease

Alzheimer’s disease is a devastating neurodegenerative disorder that robs sufferers of memory and cognition. In the brains of afflicted humans, clumps of protein called amyloid plaques accumulate, derived from fragments of the amyloid precursor protein (APP).

Scientists have built several mouse strains that overexpress a mutant version of human APP first identified in two Swedish families. Those families develop Alzheimer’s unusually early, in their fifties, providing a genetic shortcut for researchers.

To gauge memory loss in these mouse models, investigators employ classic behavioral tests such as the Morris water maze – a pool where a hidden platform forces the mouse to remember its location – and the novel object recognition test, which pits a familiar object against a new one to see if the mouse shows a preference for novelty. Alzheimer’s mice notoriously fail the latter, indicating impaired recognition memory.

8 Measles

Measles, a viral scourge that typically causes fever and a characteristic rash, can occasionally lead to brain inflammation or even death in severe cases. In nature, the virus is a strict human pathogen, entering cells via either the CD46 or CD150 receptors.

To make mice vulnerable, researchers have inserted the human genes encoding these receptors into the mouse genome. Once equipped with the proper doorway, the mice can be infected with measles virus and display a range of disease outcomes.

One landmark 2006 study introduced the human CD150 receptor into mice and then challenged them with measles either through a nasal spray or direct brain injection. The result was a dramatic spectrum: newborn mice invariably succumbed, four‑week‑old mice survived unscathed, and the intermediate ages showed mixed mortality.

The age‑dependent severity underscores how developmental stage influences immune response, offering a valuable platform for testing antiviral therapies and vaccine safety.

7 HIV

Since the start of the AIDS epidemic, HIV has claimed roughly 39 million lives, with millions more living with the virus today. The virus gains entry to human cells by latching onto specific surface receptors, a mechanism it shares with our close relatives, the chimpanzees.

However, mice are evolutionarily distant – about 90 million years of separate evolution – and their receptor proteins have diverged enough that HIV cannot infect them naturally.

One solution is to transplant at least three human genes that encode the essential entry factors into the mouse genome, creating a permissive environment for HIV replication.

A more popular strategy involves generating “humanized” mice, wherein scientists replace the mouse’s immune system with human immune cells. These mice become a living laboratory for HIV infection studies.

Among the humanized models, the BLT mouse – named after the sandwich of bone marrow, liver, and thymus – stands out. Researchers start with an immunodeficient mouse, graft human fetal liver and thymus tissue under its kidney capsule, and inject human bone‑marrow‑derived stem cells.

The resulting animal is teeming with human immune cells and can be infected via mucosal routes (vaginal or anal) or directly through intravenous injection, providing a realistic platform for testing vaccines, therapeutics, and cure strategies.

6 Acne

Acne is a uniquely human skin condition that our closest primate cousins, the chimpanzees, simply don’t get. The culprit is the bacterium Propionibacterium acnes, which normally lives peacefully on the skin but can turn hostile when oxygen levels plummet inside a clogged pore.

When P. acnes goes rogue, it triggers an inflammatory cascade that leads to the classic pus‑filled lesions we all know and (sometimes) dread.

Scientists have tried to replicate acne in mice by injecting the bacterium directly into the mouse ear or back, but the microbe prefers human skin and rarely flourishes in the rodent environment.

To coax the bacteria into a mouse‑friendly niche, a research team built tiny Teflon cylinders – essentially micro‑bioreactors – filled them with human skin cells and surgically implanted them into the mouse abdomen.

After a week, they introduced P. acnes into those cylinders. The human cells survived, the bacteria colonized them, and the mouse’s immune system reacted with a response that closely mirrors the early stages of a human acne flare, giving researchers a window into the disease’s initiation.

5 Obsessive‑Compulsive Disorder

Obsessive‑compulsive disorder (OCD) drives people to repeat actions – think endless hand‑washing or compulsive counting – often to alleviate anxiety. Mice don’t wash their hands, but they do groom themselves, a behavior that can become excessive and serve as a proxy for human OCD.

Excessive grooming in rodents has been linked to hyperactivity in the orbital frontal cortex, a brain region that shows heightened activity in many OCD patients.

To model this, neuroscientists used optogenetics to flash light pulses onto the orbital frontal cortex of mice over several days. The repeated stimulation caused the animals to groom far more than normal, and the behavior could be dampened with a drug that also works in human OCD treatment.

Genetic approaches have also yielded OCD‑like mice. Mutations in the Hoxb8 gene produce rodents that over‑groom to the point of self‑hair loss, while Sapap3‑deficient mice compulsively rub their faces, sometimes causing wounds – both striking analogues of human compulsive rituals.

4 Alcoholism

Alcoholism, or alcohol use disorder, is characterized by a physical dependence on ethanol, intense cravings, and a pattern of heavy drinking. In people, the condition often runs in families, suggesting a genetic component.

Mouse strains show a similar genetic split: some sip barely any alcohol when given a chance, while others eagerly consume large quantities.

Complicating matters, mice metabolize ethanol roughly five times faster than humans, making it tricky to achieve a genuinely “drunk” state without forced administration.

Researchers overcame this by selectively breeding for high‑alcohol‑preferring (HAP) mice. Each generation, they kept only the individuals that drank the most, eventually creating a line that voluntarily drinks copious amounts of ethanol.

When given extended access, HAP mice can reach blood‑alcohol levels more than three times the legal driving limit, stumbling, losing balance, and struggling to stay on a narrow beam – a clear sign of intoxication.

Crucially, these mice still have the option to drink water, yet they overwhelmingly choose alcohol, mirroring the compulsive nature of human alcoholism.

3 Huntington’s Disease

Huntington’s disease is a hereditary neurodegenerative disorder that gradually erodes motor control and cognitive function. The disease stems from an expanded stretch of CAG repeats in the huntingtin (HTT) gene on chromosome 4; normal alleles have fewer repeats, while disease‑causing versions carry more than 35.

Scientists have engineered mice to carry a mutant human huntingtin gene containing 72 CAG repeats, far beyond the pathological threshold.

These transgenic mice develop striking motor deficits: they stumble on balance beams, lose footing when lifted by the tail, and even wander in circles, recapitulating the gait abnormalities seen in patients.

Post‑mortem analysis reveals progressive brain degeneration reminiscent of human Huntington’s pathology. Beyond the full‑length mutant, researchers have produced a variety of strains that express only fragments of the gene or restrict expression to specific brain regions, each offering unique insights into disease mechanisms.

2 Autism

Autism spectrum disorder (ASD) manifests as difficulties in social interaction, communication challenges, and repetitive behaviors such as hand‑flapping. A multitude of genes contribute to risk, with one notable player being Cntnap2, important for early brain wiring.

In a landmark study, researchers knocked out the Cntnap2 gene in mice. The resulting animals displayed altered brain development: certain neuronal populations failed to migrate correctly, and levels of inhibitory interneurons dropped.

Behaviorally, Cntnap2‑deficient pups emitted fewer distress calls when separated from their mothers, indicating reduced communicative drive. As adults, these mice showed little interest in exploring a novel mouse‑containing tube versus an empty one, reflecting diminished social curiosity.

They also exhibited stereotyped, repetitive actions – relentless digging and excessive grooming that sometimes led to self‑injury – echoing core autistic traits.

Treatment with risperidone, an antipsychotic commonly prescribed for autistic irritability, successfully curbed the repetitive behaviors in these mice, though social deficits persisted, mirroring the partial efficacy seen in human patients.

1 Schizophrenia

Schizophrenia is a complex mental illness marked by hallucinations, delusional thinking, apathy, and learning difficulties. In affected individuals, a specific type of brain cell called the MD neuron shows reduced activity.

To mimic this, scientists chemically silenced MD neurons in mice, which then struggled to adapt to new rules in a food‑finding task – a behavioral echo of the cognitive deficits observed in patients.

Genetically, the disorder runs in families, and many genes have been implicated. One Scottish family carries a mutation in the DISC1 gene, which researchers introduced into mice to study its effects.

DISC1‑mutant mice develop enlarged lateral ventricles, especially on the left side, a neuroanatomical hallmark also seen in some schizophrenic patients.

These mice display a mixed bag of behaviors: some become hyperactive, racing around open fields, while others show reduced effort when placed in water, suggesting apathy. Although these phenotypes hint at schizophrenia‑like traits, the precise connection remains uncertain.

Whether mice will ever be engineered to produce classic hallucinations or delusional narratives remains speculative – such subjective experiences likely require a human brain. Still, the models provide invaluable windows into the disorder’s biology.

Since the 1920s, our understanding of the universe has greatly expanded. Edwin Hubble, the man who the famous Hubble Space Telescope was named after, helped to shatter the illusion that ours was the only galaxy in the universe with his observations of what would later be called the Andromeda galaxy.

With the James Webb Space Telescope finally launching and reaching its final cosmic docking spot in Earth’s L2 Lagrange point, we have an entirely new era of astronomy to look forward to, as once the telescope’s instruments are fully ready, it boasts the ability to peer back in time to the first luminous glows erupted after the Big Bang.

But that doesn’t mean that observatories like the Hubble Space Telescope will be out of the job, as even 32 years after the telescope’s launch, it is still being used to do groundbreaking scientific work.

Today we’re looking at the 10 most breathtaking images ever taken in the known universe.

10. Cosmic Cows

What is a cosmic cow?

No, we haven’t launched some poor hapless bovine into space, at least not yet, but rather, the term refers to an extremely bright form of supernovae. The first of these cow-like flashes of light was discovered in 2018 thanks to the efforts of astronomers operating two different telescopes, the Neil Gehrels Swift Observatory and the Nuclear Spectroscopic Telescope Array. 

The newly discovered celestial explosion was dubbed AT2018cow and the name just sort of stuck, becoming a catchall for any supernovae which match its unique description. 

Cow-like supernovae are very short-lived and AT2018cow was 100 times more luminous than a typical supernova, emitting brilliant ultraviolet and blue light. These newly discovered explosions also make up about 0.1 percent of all observed cosmic blasts in the night sky.

And, at the start of this year, another cow-like event was discovered in the Spektrum-Roetgen-Gamma (SRG) space telescope’s data. This one being 200 times as bright as the original cosmic bovine. 

According to Caltech astronomer Yuhan Yao, these events are more than likely the result of a collapsing star giving birth to a black hole or neutron star with a powerful magnetic field. 

9. Henize 2-10 Stellar Nursery

Black holes are typically depicted as silent monsters, lurking in the black of space waiting to gobble up unsuspecting worlds and stars. Yet, without them, we would likely not be here. For one, the supermassive black hole at the center of the Milky Way binds our galaxy together, making our very existence possible.

However, what was discovered by the Hubble Telescope in a dwarf starburst galaxy 34 million light-years from us is perhaps proof that black holes assist in the formation of new stars. 

Henize 2-10 has been the source of some debate since the discovery of what appears to be a massive black hole at the galaxy’s core, but the data suggesting that the object at the core could also suggest a supernova remnant. However, in these stunning recent images from Hubble, we see an outflow of gas coming from the object, leading directly to a stellar nursery. 

If this object is indeed a black hole, then it will prove that black holes play a pivotal role in new star formation.

8. N44 Nebula

Located within the Large Magellanic Cloud, the N44 nebula as it was captured by the Hubble Space Telescope is absolutely stunning to behold, but more important are the cosmic phenomena which contribute to its awe-inspiring beauty.

The titular super bubble spans nearly 250 light-years, and currently, there’s no one explanation for why N44 has a massive hole in it, but stellar winds coming from massive stars and a supernova remnant have been offered as potential explanations.

7. Centaurus A Radio Galaxy

The Centaurus A Radio Galaxy might be the fifth brightest galaxy visible in the Earth’s night sky, but it’s also one of the most heavily studied objects in all of astronomy. 

This particular image, which shows Centaurus A’s supermassive black hole’s powerful relativistic jets in all of their terrifying glory, is a composite of three different images captured by three separate instruments. 

Each instrument operates in different wavelengths of the light spectrum. The orange segments of the image are from LABOCA on APEX, the blue portions are from x-ray data captured by the Chandra X-ray Observatory, and everything else was captured using the MPG/ESO telescope located in La Silla, Chile.

6. Intersecting Galaxies

Hubble has had an incredible run since its debut in 1990.

It is said that one day, the Milky Way and Andromeda Galaxy will collide and merge together (and some data suggests that that process has already started, but that’s neither here nor there). 

Speaking of Andromeda, the constellation not the galaxy. This image represents ARP 273, two colliding galaxies some 300 million light-years from our humble little solar system. 

While some places describe this interaction as having created what looks like a beautiful rose or flower formation, others describe the galaxy making up the “stem” of the flower as though it’s making a harrowing kamikaze dive into the other spiral galaxy. 

The gravitational forces at play here are actively distorting both galaxies into their current shape, offering us a preview of sorts for what might happen when the Milky Way and Andromeda Galaxy are further along with their merger.

5. Star Cluster R136

Located within the Tarantula Nebula which itself is located within the Large Magellanic Cloud, star cluster R136 is a sight to behold. 

This sector of the nebula features dozens upon dozens of newborn blue stars. These are some of the most massive stars in the entire universe. 

This particular image was captured by the Hubble Space Telescope, through a partnership between NASA and ESA astronomers who were studying the Tarantula Nebula using Hubble’s spectrograph instrument.

Among these glowing blue stars, which are located 170,000 light-years from us, are 9 heavyweight stars with masses 100 times than that of our sun, Sol. 

4. V838 Monocerotis

V838 Monocerotis is a variable star and surrounding it is a structure of interstellar dust. Hubble was able to capture this incredible image after V838 Monocerotis brightened by an extreme amount at the start of 2002. 

For a brief moment in time (cosmically speaking, of course), the variable star was 600,000 times brighter than Sol. The brightening of this star lasted from January to April of 2002, and the cause for this flare is still a mystery. But, as a result, we have this stunning image of what’s called a “light echo” from the star’s brightening. 

According to NASA, light from V838 Mon “propagates outward. Each new observation of the light echo reveals a new unique “thin-section” through the interstellar dust around the star.” In other words, as that light travels to us, we see the star’s light reflected on the interstellar gas that surrounds the star, even after the star has quieted down.

However, V838 Monocerotis is still one of the brightest stars in all the Milky Way. 

3. Pillars of Creation

Located some 7,000 light-years from the Earth, the Eagle Nebula is also home to one of the most famous images ever taken by Hubble, the Pillars of Creation. 

Like the twisted and writhing hand of a dead god, the Pillars of Creation is composed of three trails of beautiful multicolored dust and gas that stretch on for four to five light-years. 

The Pillars are composed of nitrogen, hydrogen, oxygen, and sulfur, but the most incredible thing about this formation is the fact that it’s home to a bunch of newly formed stars.

Unfortunately, the light from those newborn stars is also eroding the structure. 

The structure was originally photographed by Hubble in 1995 and it’s been photographed two more times since then. The ESA’s Herschel Space Observatory photographed the structure in 2011, and after that, Hubble took another crack at it to celebrate the space observatory’s 25^th anniversary. 

2. Ring Nebula

The Ring Nebula sits 2,000 light-years from the Earth, and it’s a hint at the haunting future that awaits our own sun someday billions of years into the future. When stars like our own finally die, they don’t explode with the fury of a supernova.

They just aren’t large enough for that. 

Instead, they slowly lose their outer layers, until they come to spread out, much like we see in the Ring Nebula. They also leave behind a remnant of the star’s core, known as a white dwarf. 

All of these features are present in this stunning image taken by Hubble in 1998. Originally, it was thought that the Ring Nebula was shaped exactly how we see it, but in recent years it’s been revealed through careful analysis of the planetary nebula that the blue regions (which are composed of helium, hydrogen, and oxygen) are actually shaped more like a football that’s intersecting with the red colored donut-shaped nitrogen and sulfur gasses. If were we to observe the nebula from a different perspective, it might look more like someone had spiked a football right through the reddish gasses. 

1. M87 Supermassive Black Hole

Of course, no list of the greatest astronomy images ever taken (or in this case, generated) would ever be complete without the first image ever taken of a black hole.

M87 (or Messier 87) is a supermassive black hole resting at the center of a supergiant elliptical galaxy. The galaxy sits within the constellation Virgo and features a unique view at a single relativistic jet coming from one end of the galaxy. 

The relativistic jet is moving so fast that it creates an illusion when we observe it from the Earth, making it appear to be moving 4 to 6 times the speed of light. 

The first image of the black hole was made in 2019 by the Event Horizon Telescope which is a collaborative effort made by multiple radio observatories around the globe. Essentially, the EHT has linked 9 observatories that function as an Earth-sized Interferometer. 

Since that first image from 2019, the EHT team has been studying M87 in even greater detail. Just last year, they released another image of the supermassive black hole showing how the stellar beast’s magnetic field disrupts the material in the accretion disk. The EHT team has since announced that it will be focusing its network of observatories on Sagittarius-A, the supermassive black hole that rests at the center of the Milky Way, which has never been directly imaged before.
