When you think of groundbreaking women in science, the name Marie Curie often jumps to mind. But the roster of pioneering female researchers runs far deeper, filled with brilliant minds whose contributions were dimmed by a biased establishment. These ten scientists pushed the boundaries of astronomy, physics, chemistry, and genetics, only to see their achievements minimized or stolen. Let’s set the record straight.

Celebrating Groundbreaking Women Who Changed Science

10 Vera Rubin b. 1928

Vera Rubin’s path to the stars was riddled with snide remarks and outright hostility. When she proudly announced her acceptance to Vassar, her high‑school physics teacher responded, “That’s great. As long as you stay away from science, it should be okay.” Undeterred, she applied to Princeton’s astronomy program, only to be rejected because the school didn’t admit women. She eventually earned a Ph.D. at Georgetown, where she teamed up with Kent Ford.

Rubin and Ford made the startling observation that stars on the outer edges of spiral galaxies rotate just as quickly as those near the centre. At the time, conventional wisdom held that gravitational pull should weaken with distance, causing outer stars to lag. Their data instead supported Fritz Zwicky’s earlier hypothesis that an invisible “dark matter” halo must be holding the galaxies together.

Rubin’s meticulous measurements showed that dark matter accounted for roughly ten times the amount previously estimated—up to 90 % of the universe’s total mass. Male colleagues dismissed her findings as impossible under Newtonian physics, branding her work as miscalculations. Both her master’s and doctoral theses were ignored, yet the evidence was undeniable. Only after other astronomers validated her results did the scientific community finally acknowledge her contribution, though she still awaits a Nobel Prize.

9 1979

Cecilia Payne’s journey began with a scholarship to Cambridge in 1919, where she studied botany, physics, and chemistry—yet Cambridge didn’t even award degrees to women then. While at Cambridge she fell in love with astronomy, prompting a transfer to Radcliffe where she earned the first Ph.D. in astronomy awarded to a woman.

By age 25 she had published six papers and, most importantly, determined the elemental composition of stars. She argued that hydrogen and helium dominate stellar interiors—an insight that upended the prevailing view of stellar chemistry. However, senior astronomer Henry Norris Russell vehemently discouraged her from publishing, claiming the results contradicted accepted knowledge and would never be accepted.

Four years later Russell independently reached the same conclusion about the Sun’s makeup, publishing his own papers and receiving full credit. Payne’s own contribution was largely erased from the historical record, though she eventually received the Henry Norris Russell Prize—an ironic nod to the very man who had suppressed her work.

8 1997

Born in China and later naturalized as an American, Chien‑Shiung Wu contributed to the Manhattan Project before turning her attention to a foundational principle in particle physics: the conservation of parity. The law posited that the universe should behave the same way as its mirror image—an idea championed by many physicists of the era.

Physicists Chen‑Ning Yang and Tsung‑Dao Lee hypothesized that parity might be violated and enlisted Wu to test their theory. Using cobalt‑60, Wu performed a series of elegant experiments that showed electrons were emitted preferentially in one direction, proving that the mirror‑symmetry assumption was false.

Her results shattered a 30‑year‑old belief and forced a reevaluation of fundamental symmetries. Yet when the Nobel Committee awarded the 1957 Prize to Yang and Lee, Wu’s crucial experimental work received no mention, leaving her legacy obscured despite the pivotal role she played.

7 1912

Chromosome research in the early 1900s revealed that sex is determined by the X and Y pair. While textbooks often credit Thomas Morgan with this discovery, the credit truly belongs to Nettie Stevens. Working independently on mealworm chromosomes, Stevens demonstrated that the presence of a Y chromosome dictated male development.

Although she collaborated with Morgan, most of the critical observations were hers. Morgan later received the Nobel Prize for work that leaned heavily on Stevens’ findings, and even went so far as to diminish her role in a Science article, calling her a mere technician—a claim later debunked by historians.

6 1978

Ida Tacke (often cited as Ida Noddack) made two remarkable contributions to chemistry. First, she identified the existence of element 75, rhenium, confirming Mendeleev’s prediction. She also reported a second element at atomic number 43, which she called “masurium.” The element was later synthesized by Carlo Perrier and Emilio Segre and renamed technetium, with the original discovery credit stripped from Tacke.

Beyond her work on the periodic table, Tacke authored a paper describing the process of nuclear fission five years before the term existed. She proposed that bombarding heavy elements with neutrons could split the nucleus and release vast energy—a concept later taken up by Lise Meitner and Otto Stern. Yet again, her insight was ignored until the Manhattan Project era, when Enrico Fermi received the Nobel Prize for related discoveries.

5 2006

Esther Lederberg’s scientific brilliance was constantly eclipsed by her husband, Joshua Lederberg. The pair worked side by side on bacterial genetics, yet Joshua alone collected the accolades, including a Nobel Prize. Esther’s own landmark achievement was the invention of replica plating—a technique that uses a piece of velvet to transfer bacterial colonies while preserving their original spatial arrangement.

Her method revolutionized microbiology, allowing scientists to study large numbers of colonies simultaneously. Despite this, the academic community repeatedly downplayed her role; Stanford demoted her to adjunct professor, while Joshua was promoted to department chair. Esther’s contributions remain a testament to the often‑overlooked work of women in genetics.

4 1968

The discovery of nuclear fission is usually credited to Otto Hahn, but the theoretical groundwork was laid by Lise Meitner. Working in secret during World War II, Meitner corresponded with Hahn as he bombarded uranium with neutrons. When Hahn’s experiments produced unexpected barium fragments, Meitner proposed that the uranium nucleus had split—a hypothesis she refined with her nephew Otto Frisch.

Meitner also noted that elements heavier than uranium do not occur naturally and that fission could unleash enormous energy. Yet the paper announcing the discovery listed only Hahn and his collaborator Fritz Strassmann, leaving Meitner absent. The Nobel Committee later awarded Hahn the 1944 Prize, calling Meitner’s omission a “mistake.” In recognition of her legacy, element 119 has been named “Mendelevium” after her—though she never received a Nobel.

3 1921

Henrietta Leavitt spent her career as a “computer” at Harvard, painstakingly cataloguing the brightness of variable stars. Paid a meager 30 cents an hour, she discovered a reliable relationship between a Cepheid variable’s pulsation period and its intrinsic luminosity. This period‑luminosity relationship allowed astronomers to gauge stellar distances simply by measuring how bright a star appeared.

Leavitt’s breakthrough opened the door to measuring the scale of the universe; it showed that distant “nebulae” were actually entire galaxies. Yet when Harvard director Edward Charles Pickering refused to credit her, her work was largely forgotten. Later, Harlow Shapley and Edwin Hubble used her relationship to map the cosmos, while Leavitt herself never received the recognition she deserved.

2 Jocelyn Bell Burnell b. 1943

Inspired by her father’s books, Jocelyn Bell Burnell pursued physics at the University of Glasgow and later a Ph.D. at Cambridge. While working under Antony Hewish on a radio‑telescope project, she noticed a series of regular pulses arriving from a single point in the sky.

These signals turned out to be emitted by rapidly rotating neutron stars—objects later named pulsars. Although Bell Burnell made the original observation and identified the phenomenon, the paper’s authorship listed Hewish first, and he received the 1974 Nobel Prize for the discovery. Bell Burnell’s contribution is now universally acknowledged, but the initial omission highlights the gender bias of the era.

1 958

Rosalind Franklin’s meticulous X‑ray diffraction work laid the foundation for deciphering DNA’s double‑helix structure. By age 33, she had produced the iconic “Photo 51,” revealing the molecule’s helical geometry and confirming a two‑strand backbone with a phosphate backbone.

Watson and Crick, visiting King’s College, were shown Franklin’s unpublished images and data by colleagues Maurice Wilkins and Max Perutz. Armed with this information, Watson and Crick constructed their famous model and published it in 1953, securing the Nobel Prize in 1962. Franklin’s own paper, published after theirs, was framed as a confirmation rather than a discovery, and she never received the credit she deserved before her untimely death.

Despite the oversight, Franklin’s legacy endures; she is celebrated as a pioneer of molecular biology and a symbol of women’s contributions to science.

2025 has already delivered a cascade of unprecedented events, and the 10 groundbreaking 038 moments we’ve witnessed so far prove that history is being written in real time. From religious milestones to daring space feats, from cutting‑edge genetic cures to the revival of extinct predators, each “first” reshapes the world we thought we knew. Grab a seat, because we’re counting down the ten most jaw‑dropping breakthroughs that have defined this remarkable year.

10 groundbreaking 038: A Year of Firsts

10 The First American Pope Is Elected

Following the passing of Pope Francis on April 21, 2025, the College of Cardinals convened in Vatican City for a conclave to select his successor. The decisive moment arrived on May 8, 2025 when the iconic white smoke rose from the Sistine Chapel, announcing that a new pontiff would soon step onto the world stage, marking a striking geographic shift for the centuries‑old institution.

Historically, the papacy has been dominated by Italians—217 of the 267 popes hailed from Italy. While the past century saw a modest increase in non‑Italian pontiffs, an American had never before ascended to the role. That changed when Cardinal Robert Francis Prevost, a 69‑year‑old native of Chicago, Illinois, emerged onto St. Peter’s Basilica balcony as Pope Leo XIV, becoming the first U.S.‑born pope in the annals of Catholic history.

9 Infant Becomes First Patient to Undergo Gene‑Editing Treatment

Kyle “KJ” Muldoon Jr., born in August 2024, entered the world with carbamoyl‑phosphate synthetase 1 (CPS1) deficiency—a rare metabolic disorder that triggers toxic ammonia accumulation, ravaging the liver and leading to irreversible neurological damage. Conventional therapy offered only a liver transplant, a procedure KJ could not undergo until his first birthday.

Long before KJ’s birth, researchers at the University of Pennsylvania had been developing a novel gene‑editing approach that had never been trialed in humans. When KJ’s case surfaced, a coalition of more than 45 scientists, physicians, and biotech firms rallied to accelerate a potential cure, racing against the clock to save his life.

Employing CRISPR—the Nobel‑winning genome‑editing tool—the team pinpointed the pathogenic mutation in KJ’s DNA and engineered a therapeutic edit that would flip the errant “letter” back to normal. The FDA granted an emergency use exemption, allowing the experimental therapy to proceed despite the lack of traditional testing. KJ’s parents faced a stark choice: stick with standard medication until a transplant became viable, or gamble on an untested, cutting‑edge intervention. They opted for the CRISPR‑based treatment.

On February 25, 2025, KJ received his inaugural infusion, followed by monthly doses in March and April. The nine‑and‑a‑half‑month‑old infant showed no serious adverse effects and began hitting developmental milestones. While it is premature to declare a full cure, KJ’s condition has markedly improved, illustrating the promise of the first‑ever patient‑specific gene‑editing therapy.

8 Turning Air into Fuel—Literally

Imagine a solution to the climate emergency that isn’t buried underground but floats right above us. That’s the premise behind a solar‑powered direct‑air‑capture (DAC) reactor unveiled by Cambridge University researchers in February 2025. Inspired by photosynthesis, the device acts as a sophisticated sponge, drawing carbon dioxide from ambient air during nighttime and harnessing sunlight by day to trigger a chemical transformation into synthesis gas (syngas), a vital feedstock for fuels, chemicals, and pharmaceuticals.

The breakthrough lies in the reactor’s independence from fossil‑fuel‑based power. Traditional carbon‑capture and storage (CCS) systems often rely on combustion to run the capture process, which paradoxically adds more CO₂ to the atmosphere. Cambridge’s unit, however, operates entirely on solar energy, eliminating the need for external electricity, batteries, or cables.

Beyond its clean power source, the reactor sidesteps the long‑standing challenge of storing captured CO₂ deep underground—a practice fraught with safety and permanence concerns. By converting CO₂ on‑site into useful syngas, the technology delivers a dual advantage: it removes a greenhouse gas while simultaneously producing a renewable energy carrier.

This innovation could reshape climate mitigation strategies, offering a compact, self‑sustaining system that both cleans the air and fuels the future without the logistical headaches of transport and sequestration.

7 The World’s First De‑Extinction

The dire wolf, immortalized by HBO’s “Game of Thrones,” once prowled North America as a top predator before vanishing roughly 10,000–13,000 years ago. On April 7, 2025, Dallas‑based biotech firm Colossal Biosciences announced a stunning achievement: the revival of the dire wolf in the 21st century, marking the world’s inaugural de‑extinction effort.

Scientists extracted ancient DNA from a 13,000‑year‑old tooth and a 72,000‑year‑old skull, assembling two complete genomic blueprints. By comparing these sequences to those of the gray wolf—the closest living relative—they engineered a genome that recapitulated the distinctive traits of the extinct species. The modified DNA was inserted into a domestic‑dog egg, and the resulting embryos were implanted into surrogate mothers.

The venture culminated in the birth of three pups—two males named Romulus and Remus and a female dubbed Khaleesi. Although they are not carbon copies of their prehistoric ancestors, the puppies embody the essential genetic hallmarks of the dire wolf. The project sparked debate over the ethics of resurrecting extinct taxa, yet Colossal reassured the public that the wolves will reside in a 2,000‑acre, USDA‑registered preserve certified by the American Humane Society, never to be released into the wild.

By sidestepping the fictional calamities of “Jurassic Park,” the initiative demonstrates a cautious yet bold step toward restoring lost biodiversity, opening a new frontier in conservation biology.

6 Trump Makes a Grover Cleveland Comeback

Whether you admire him or despise him, Donald Trump etched his name into the record books in 2025 by becoming the first U.S. president since Grover Cleveland to serve non‑consecutive terms. Sworn in as the 47th president on January 20, 2025, he also claimed the title of the oldest commander‑in‑chief ever inaugurated—78 years and 220 days—surpassing Joe Biden’s previous record of 78 years and 61 days.

Beyond the age milestone, Trump became the first individual with a felony conviction to ascend to the nation’s highest office. These unprecedented achievements signal a new political epoch, one that scholars anticipate will be dissected and debated for generations to come.

5 The Moon Gets a Clean Landing—Finally!

Private enterprises have long pursued lunar touchdowns, yet many attempts have ended in imperfect landings. In February 2024, Intuitive Machines dispatched the Odysseus lander, marking the first U.S. spacecraft on the Moon in over half a century, but the vehicle tipped over on impact, failing to achieve a textbook landing.

March 2025 saw a breakthrough when Firefly Aerospace’s Blue Ghost Mission 1 successfully delivered payloads, harvested lunar samples, and captured high‑resolution imagery for NASA. Launched on January 15, 2025, the spacecraft touched down at Mare Crisium on March 2, 2025 at 3:34 a.m., executing a flawless, upright landing without any technical glitches.

This accomplishment crowned Firefly as the first private company to nail a perfect lunar touchdown, suggesting that commercial players are now poised to drive the next wave of lunar commerce and exploration.

4 The Most Elusive Ocean Animal Captured on Video

Colossal squids, capable of reaching up to 23 feet in length and weighing as much as 1,100 pounds, have long eluded scientists since their first description in 1925. Their deep‑sea habitat—ranging from 1,640 to 6,560 feet below the surface—combined with crushing pressure, near‑freezing temperatures, and perpetual darkness, renders them virtually inaccessible.

Adding to the mystery, their enormous eyes—larger than soccer balls—are highly light‑sensitive, prompting the creatures to avoid artificial illumination from research equipment. Consequently, knowledge of their behavior has been limited to stomach contents found in predator carcasses.

On March 9, 2025, a serendipitous encounter occurred when an underwater robot deployed by the Schmidt Ocean Institute filmed a juvenile colossal squid near the South Sandwich Islands. The one‑foot‑long individual was captured at a depth of 1,968 feet (600 meters), providing the first live visual documentation of the species and opening new avenues for marine research.

3 Parkinson’s Research Reaches Incredible New Depths

Parkinson’s disease, the fastest‑growing neurodegenerative disorder, now affects over 10 million individuals worldwide, yet a definitive cure remains elusive. A breakthrough study published in Science on March 13, 2025 unveiled how researchers at Australia’s Walter and Eliza Hall Institute of Medical Research (WEHI) visualized the interaction between the protein PINK1 and damaged mitochondria using cryo‑electron microscopy and mass spectrometry.

PINK1 (PTEN‑induced putative kinase 1) mutations are known to trigger early‑onset Parkinson’s, but until now, scientists had never directly observed how the protein binds to the surface of compromised mitochondria or how it becomes activated.

The team identified four distinct steps governing PINK1’s attachment and activation on faulty mitochondria. Understanding these mechanisms offers a roadmap for developing therapies that could switch off the pathogenic activity of mutant PINK1, potentially slowing disease progression and paving the way for disease‑modifying treatments.

2 Oxygen Discovered in the Most Distant Galaxy

In January 2024, the James Webb Space Telescope uncovered a luminous galaxy, JADES‑GS‑z14‑0, situated 13.4 billion light‑years away—the most distant galaxy observed to date. This object represents the universe when it was less than 300 million years old, roughly 2 % of its current age.

Follow‑up observations using the Atacama Large Millimeter/submillimeter Array (ALMA) in April 2025 revealed a surprising chemical composition: the presence of oxygen and heavy metals. Typically, early galaxies consist mainly of hydrogen and helium, with heavier elements forged later in stellar cores and dispersed by supernovae.

The detection of oxygen at levels ten times higher than expected suggests that JADES‑GS‑z14‑0 experienced rapid star formation for at least 100 million years before we observed it, indicating that galactic evolution proceeded much faster than previously thought.

1 President Trump Pardons a Corporation

Presidential pardons have historically freed individuals ranging from political allies to whistleblowers. In 2025, however, a novel form of clemency emerged when President Trump granted a full, unconditional pardon to HDR Global Trading, the parent company of the cryptocurrency exchange BitMEX, along with three of its co‑founders and one employee.

BitMEX had been penalized on January 15, 2025 with a $100 million criminal fine and an additional $130 million in civil penalties for violating the Bank Secrecy Act by operating without a proper anti‑money‑laundering program. The unprecedented corporate pardon ignited a firestorm of political debate, raising profound questions about the ethical and legal ramifications of extending presidential clemency to for‑profit entities.

Ten groundbreaking tattoos capture the imagination, blending art, science, and centuries‑old mystery into skin‑deep stories. Getting inked is already a serious commitment, but when the tattoo itself tells a tale of ancient peoples, cutting‑edge medicine, or futuristic robots, the experience becomes something truly unforgettable.

Ten Groundbreaking Tattoos Overview

10 Unlocking the Secrets of Ötzi the Iceman

Back in 1991, archaeologists uncovered a 5,300‑year‑old frozen body high in the Alps, christening him Ötzi the Iceman. The icy corpse bore 61 carbon‑based markings, a prehistoric tattoo gallery that left scientists buzzing.

Curiosity sparked a debate: how were those ancient designs created? Some scholars argued for soot rubbed into shallow cuts, while others imagined fire‑heated plant material searing the skin. Fast forward to 2022, a coalition of researchers and tattoo artists set out to test these theories on a living canvas—Danny Riday, a seasoned tattooist from New Zealand.

The experimental team deliberately limited themselves to tools that could have existed in Ötzi’s era. They wielded animal bone, obsidian shards, and boar tusk, employing methods such as hand‑tapping and hand‑poking to replicate the ancient motif on Riday’s leg.

After cataloguing every imprint, the researchers concluded that Ötzi’s tattoos most likely resulted from a simple hand‑poking technique using a single‑pointed implement. “We ultimately propose that Ötzi’s tattoos were made by puncture, probably with a bone or copper awl,” explained archaeologist Aaron Deter‑Wolf.

9 Why Doctors Might Choose to Mark Your Colon

When you picture a tattoo, the colon rarely makes the shortlist. Yet surgeons sometimes need a reliable way to highlight internal lesions or tiny cuts during operations, and ink offers a permanent, visible marker. Traditional internal tattoos use carbon black, but they can seep and cause complications.

In 2022, a team affiliated with the American Chemical Society unveiled a novel colon‑tattoo ink composed of biodegradable nanoparticles and polymers. This new formulation improves visibility while minimizing leakage, as demonstrated in tests on pig intestines and live mice.

The researchers envision extending this technology beyond the colon, potentially marking tumors throughout the gastrointestinal tract or even the pancreas, thereby enhancing precision in future surgeries.

8 Color Changing Inks That Track Glucose Levels

Living with chronic illnesses like diabetes or kidney disease demands constant monitoring of internal biomarkers such as glucose, albumin, and pH. In 2019, German scientists introduced a daring concept: tattoos that shift color in response to these biochemical signals.

Initial trials on pig skin revealed that the inks could blaze through a vivid spectrum as researchers manipulated specific biomarker concentrations. While the pH sensor proved reversible, the glucose and albumin indicators functioned only once before fading, highlighting both promise and current limitations.

Although still far from human application, these color‑changing tattoos hint at a future where a simple glance at your skin could convey vital health data without needles or devices.

7 Medieval Christian Body Art Found in Africa

Archaeologists excavating a Sudanese burial site unearthed a remarkable find: a medieval individual bearing Christian symbols inked on his right foot. The tattoo displayed four Greek letters—Chi and Rho merged into a Christogram, alongside Alpha and Omega, representing the beginning and the end.

The discovery emerged from the Ghazali monastery complex, a 7th‑century religious hub nestled in the Bayuda Desert. Hundreds of graves span four cemeteries there, and this particular burial offers a vivid glimpse into the spread of Christianity across Northeast Africa via Roman trade routes, later flourishing under the Kingdom of Makuria.

6 Tattooing Mouse Embryo Cells with Gold Dots

In 2023, a team of U.S. engineers showcased a groundbreaking technique: nanoimprint lithography, a method that “tattoos” gold nanodots and nanowires directly into living fibroblast cells harvested from mouse embryos.

The process involves using a microscopic needle to puncture individual cells, embedding them with gold structures that glitter under the microscope. Researchers believe such gilded cells could evolve into real‑time sensors, offering unprecedented insight into cellular health and behavior.

David Gracias, the study’s lead, emphasized the long‑term vision: “If we imagine where this is going, we’d like sensors that remotely monitor and control the state of individual cells and their surrounding environment in real time,” a capability that could enable earlier disease detection before organ damage becomes apparent.

5 Dutch Actress Is First Person to Be Tattooed by a Robot

Stijn Fransen, a celebrated Dutch stage and screen talent, earned a quirky claim to fame in 2021: she became the inaugural human recipient of a robot‑performed tattoo. The operation was orchestrated by artist Wes Thomas, who guided a 5G‑linked robotic arm to etch a minimalist design onto a mannequin arm before the robot transferred the work onto Fransen.

Technologist Noel Drew devoted six weeks to perfecting the robotic apparatus, experimenting on various media—including vegetables—to calibrate depth and pressure. Integrated sensors ensured the needle never breached the skin too deeply, striking a balance between precision and safety.

The resulting artwork, while understated, marked a historic convergence of art and automation, showcasing the potential for remote, highly controlled tattooing in the years ahead.

4 Quantum Dot Acts as Vaccine ID

In 2019, MIT researchers proposed an inventive solution to the persistent problem of lost or inaccessible vaccination records: invisible quantum‑dot tattoos. By embedding tiny light‑responsive particles beneath the skin at the time of immunization, a permanent, tamper‑proof record could be created.

The quantum dots are injected in patterned arrays that remain invisible under normal lighting but fluoresce under infrared illumination. Medical personnel can then read these hidden codes with a smartphone‑compatible scanner, instantly confirming a patient’s immunization status.

Early animal trials on rats yielded encouraging results, and lead scientist Robert Langer suggested that such “invisible” ink could open doors to novel data storage, biosensing, and vaccine‑tracking applications, especially in regions where conventional record‑keeping is unreliable.

3 Are Ancient Egyptian Mummy Tattoos Linked to Pregnancy?

Ancient Egypt embraced body art long before modern tattoo culture emerged. Recent investigations of mummified remains from the Deir el‑Medina workshop on the Nile’s west bank have uncovered two women bearing distinctive lower‑back tattoos.

The first, discovered about a century ago, features a string of diamond shapes positioned just above the buttocks. The second, unearthed in 2019, displays motifs of water and plant life. Scholars interpret these designs as symbols related to fertility and childbirth, perhaps representing the nurturing qualities of the Nile’s banks where pregnant or menstruating women sought comfort.

Additional female mummies exhibit tattoos on hips and necks, and one even bears an image of Bes, the protective deity of pregnancy. Collectively, these markings deepen our understanding of how ancient Egyptians intertwined art, religion, and reproductive health.

2 Tattooing Mind‑Reading Electrodes into the Human Skull

What sounds like sci‑fi is edging toward reality thanks to Brain Scientific, a startup developing e‑tattoos composed of microscopic electrodes implanted directly into the skull. These ultra‑thin sensors capture neural activity, transmitting data to a postage‑stamp‑sized processor that rests behind the ear.Co‑founder Baruch Goldstein envisions this technology revolutionizing neurological research. By providing continuous, real‑time brain‑wave monitoring, doctors could better understand conditions like epilepsy, potentially predicting seizures before they strike and delivering timely interventions.

While still in early stages, the project underscores a bold future where skin‑level tech merges seamlessly with the brain, offering unprecedented insight into our most complex organ.

1 World’s Oldest Tattoo Tools Made from Bird Bones

Archaeologists have identified the oldest known tattoo implements: sharpened turkey bones recovered from a Native American burial site in Fernvale, Tennessee. Radiocarbon dating places these tools between 3,500 and 1,600 BC, predating previous records by centuries.

Recent microscopic analysis revealed trace pigments on the bone tips—iron‑oxide red and carbon black—both historically used in tattoo inks. This discovery confirms that early peoples employed sophisticated body‑art techniques far earlier than once believed.

Prior to this find, the earliest documented tattooing instrument was a cactus‑spine needle dated to roughly 2,000 BC from Utah. The bird‑bone tools thus push back the timeline of human tattooing, highlighting a deep‑rooted cultural practice spanning millennia.

Mathematics is the study of structure, order, and relation based on the basic concepts of counting and measuring. We’ve traveled far beyond simple counting and measuring – today math underpins advanced scientific domains such as thermodynamics, rocket propulsion, and bionanotechnology. All of these achievements rest on a series of 10 groundbreaking moments that have propelled the discipline forward, each contributed by visionary thinkers, scientists, and mathematicians throughout the ages.

10 Groundbreaking Moments That Shaped the Way We Think About Numbers

10 Cartesian Geometry

Also sometimes called analytical geometry, Cartesian geometry was pioneered by René Descartes in the 17th century. It marked a revolutionary moment in mathematics by uniting algebra and geometry for the first time.

Descartes first unveiled the idea of Cartesian coordinates in his Discours de la méthode, published in 1637. He suggested that any point on a two‑dimensional plane could be identified by two numbers, representing its horizontal (x) and vertical (y) positions. This coordinate system gave mathematicians a powerful tool to solve equations both algebraically and graphically, laying essential groundwork for the later development of calculus by Newton and Leibniz.

9 Binary System

With a base of “2” and employing only the digits 0 and 1, the binary system is the simplest number system still in everyday use, yet it is arguably the most influential. It powers computer memory, where every calculation consists of two states – off and on – or bits. This elementary system underlies virtually all digital communication today, making it one of the most consequential inventions in the history of mathematics and computing.

The concept was refined and popularized by many scholars, most notably Gottfried Wilhelm Leibniz, a 17th‑century German mathematician and philosopher who also co‑invented calculus. In 1701, Leibniz published his binary system in the essay Essay d’une nouvelle science des nombres, which secured his election to the Paris Academy.

8 Difference And Analytical Engines

Charles Babbage, often hailed as the “father of the computer,” made pioneering strides in mathematics with his 19th‑century inventions: the Difference Engine and the Analytical Engine. The Difference Engine was designed to compute mathematical tables using finite differences, handling basic arithmetic operations such as addition, subtraction, multiplication, and division. It became the first automatic calculating engine in history and set the stage for modern computers.

The Analytical Engine, conceived in 1834, was a far more ambitious, general‑purpose, programmable device. It employed punched cards for data manipulation and storage—a concept borrowed from the Jacquard loom. Moreover, the Analytical Engine introduced groundbreaking features like conditional branching and looping, allowing it to execute different instructions based on previous results and repeat specific sequences of operations.

7 Turing Machine

The Turing machine was a hypothetical device conceptualized by English mathematician Alan M. Turing in 1936. It consists of an infinitely extendable tape divided into squares, each bearing a blank or a finite set of symbols. A tape head can read, write, move, and modify these squares, enabling the machine—at least theoretically—to follow instructions stored in its control mechanism.

Although purely theoretical, the Turing machine laid the groundwork for all modern digital computers. Turing’s abstraction of computation into discrete steps formed the basis for subsequent digital devices. The architecture of input‑output devices—such as tape readers, memory, and central processing units—mirrors the essential features of the Turing machine, introducing the fundamental elements of information processing and opening the door to programmable machines capable of complex calculations and logical operations.

6 Infinity

The concept of infinity has a long and intricate history within both mathematics and philosophy. Greek philosophers like Aristotle first explored the idea in antiquity, but Indian mathematician Surya Prajnapti was the first to categorize different types of infinities into enumerable, innumerable, and infinite sets. It wasn’t until the 17th century that European scholars such as John Wallis and Georg Cantor began incorporating infinity into their work, shaping the modern understanding we use today.

John Wallis, an English mathematician, introduced the infinity symbol (∞) in 1655. Later, German mathematician Georg Cantor made monumental contributions by demonstrating that not all infinities are of equal size or type. Cantor defined different levels of infinity, proving that some infinite sets are larger than others, and introduced the notion of “infinity in infinities,” which became a cornerstone of set theory and calculus.

5 Newton’s Calculus

Isaac Newton remains one of the most influential figures in the history of mathematics, largely because of his invention of calculus in the mid‑to‑late 1660s. This breakthrough revolutionized the field and paved the way for further advancements in science and engineering.

Calculus, comprising differential and integral branches, enables the study of how quantities change over time. Newton’s work on gravity and the laws of motion directly inspired his development of this new mathematical framework. Today, calculus finds applications across a spectrum of disciplines, including physics, chemistry, biology, engineering, and pure mathematics. Fields such as trend analysis, engineering design, medical modeling, and motion studies heavily rely on calculus for precise calculation and prediction.

4 Pythagorean Theorem

The Pythagorean theorem is a fundamental geometric principle that has profoundly impacted mathematics and many scientific fields throughout history. It asserts that in a right‑angled triangle, the sum of the squares of the two shorter sides equals the square of the longest side.

Although the discovery is commonly linked to the Greek philosopher‑mathematician Pythagoras, evidence suggests the concept predates him. Babylonian tablets from 1900‑1600 BC reveal an understanding of the theorem and Pythagorean triples, and the concept also appears in the Indian Baudhayana Sulba‑Sutra, written between 800 and 400 BC. Nevertheless, Pythagoras’s school in Croton, Italy, popularized the theorem, leading to its enduring fame.

3 Zero

The invention of zero stands as a monumental milestone in mathematics, fundamentally reshaping our comprehension of numbers and enabling countless advancements across scientific fields. Zero first appeared in the Bakhshali manuscript—an ancient Indian mathematical document dating to the third or fourth century. Earlier civilizations employed positional number systems, but without a proper zero, calculations were cumbersome and representing fractions was nearly impossible.

Since its emergence, zero has become an indispensable placeholder digit in number systems, simplifying arithmetic and enabling complex calculations. It facilitated the development of graphing techniques, calculus, algorithms, and many other concepts that underpin modern mathematics, acting both as an abstract notion and a concrete tool.

2 Algebra

The invention of algebra is often credited to Abu Abdullah Muhammad ibn Musa al‑Khwarizmi, a Persian mathematician born in the eighth century AD in the city of Khwarazm (modern‑day Uzbekistan). He lived during the Golden Age of Islam, when the early Abbasid caliphate fostered a flourishing of scientific and cultural activity centered in Baghdad.

Al‑Khwarizmi contributed significantly to various mathematical domains, including arithmetic, trigonometry, and astronomy. His most notable achievement, however, was his seminal work Al‑Kitāb al‑Muḫtaṣar fī Ǧabr wa‑l‑Muqābala (The Compendious Book on Calculation by Completion and Balancing), from which the term “algebra” originates.

1 Euclidean Geometry

Euclidean geometry is named after the Greek mathematician Euclid, who lived around 300 BC in Alexandria, Egypt. At its core, it studies plane and solid figures based on a set of axioms and theorems, as detailed in his magnum opus, Elements. This work compiles the mathematical knowledge of his era along with Euclid’s original contributions.

Because of its profound influence, Euclid is often called the “father of geometry.” Until the emergence of non‑Euclidean geometry in the 19th century, Elements served as the universal foundation for mathematical and geometrical thought worldwide, covering topics such as plane geometry, number theory, and the study of solid figures.

In May 1914, The Times of London, England, reported: “If all goes well with this invention, we shall soon be able, it seems, to see people at a distance.” The newspaper referred to an instrument an English inventor, Archibald Low, had come up with called a Televista. Low’s Televista was the most sophisticated device of the day, but it was a long way from being anything we would recognize as a television. And Low was not the only one working in the field.

No single person can be credited with the invention; many people contributed. A Scot, John Logie Baird, demonstrated a working system at Selfridge’s Department Store in London in 1925. In the United States, Charles Francis Jenkins was making great advances in the same year, and in Japan, Kenjiro Takayanagi demonstrated a system with much-improved resolution in 1926.

The world’s first TV station—W2XB—started broadcasting from New York City in 1928. The idea that television would be a vehicle for mass entertainment didn’t occur to these pioneers-that would have to wait until after the Second World War.

The examples here are sandwiched between Queen Elizabeth’s coronation and her funeral. In her long reign, she witnessed the growth of television from a relatively minor, expensive luxury to the ever-present phenomenon it is today. She also witnessed the following groundbreaking moments.

10 Elizabeth Takes Up the Crown

People needed something to cheer them up in a country still feeling the effects of World War II. What better than a pageant like a royal coronation? The queen demonstrated that she understood the medium’s power by insisting that the BBC could place cameras inside Westminster Abbey—something that her advisors insisted would detract from the mystery of the monarchy. But Elizabeth was not interested in mystery. She wanted to be the figurehead of a united Commonwealth.

Twenty million people watched Queen Elizabeth’s coronation live on June 2, 1953. In Britain, viewers crowded into neighbors’ houses, pubs, and cinemas to enjoy the spectacle. For the first time, more people watched a TV program than listened to a radio broadcast.

In the United States, 85 million Americans watched recorded highlights, eager to see the mysterious ceremony that had alluded so many for so long.

9 The First Step

Using a 30-line mechanical system, the BBC broadcast its first program in August 1932. John Logie Baird made an appearance to thank the corporation, and “lookers-in” (as viewers were called) also saw a performing sea lion, a demonstration of ju-jitsu, and other bits and pieces.

Our clip shows that the USA then took things a little further. At the beginning of the program, the two RCA men stress that there are still a lot of technical problems to overcome. Interestingly, they mention that television has an educational role and would be an extension of radio rather than a threat to radio.

The production quality of this program is surprisingly good, and the two men are confident that this is just the beginning. Perhaps the greatest problem would be how to make television receivers affordable.

8 Walter Cronkite Announces JFK’s Assassination

We’ve probably all seen the famous footage of the assassination of JFK in 1963. But the film was not from live TV coverage—Abraham Zapruder recorded the part of the motorcade that he could see on silent 8mm film. TV crews were waiting for President Kennedy to arrive at the Dallas Trade Mart.

Nobody thought the motorcade was important enough to call for live coverage. In hindsight, this was a pity, given the amount of speculation that is still going on about what happened that day. Reporters were quick to phone in the news. Around 70% of Americans heard about the event within half an hour of it happening.

Our clip shows how Walter Cronkite handled the news of President Kennedy’s death when sources confirmed that the President had died. Many people considered Cronkite “the most trusted man in America.” His professionalism comes through in this clip. He is affected by the news, and we can see that, but he doesn’t let his emotions get the better of him. After a short pause, he finishes the bulletin with calm confidence.

Many people knew that Kennedy had been shot, but they had no idea how serious it was. Many people heard the news that he had died from Cronkite.

7 Doctor Who?

On a more frivolous note, the day after Kennedy’s assassination, the BBC released the first episode of Doctor Who. The Time Lord is still going strong today and has an enormous international cult following.

Looking back at old episodes, the props seem amateurish and obviously fake. But the program always had (and still has) strong plot lines, a good cast, and an engaging touch of humor. The technical quality of the programs has, of course, improved beyond measure, but the program still retains its tongue-in-cheek touch.

Who can forget the first time they saw a Dalek? I can’t—at the age of seven, I hid behind the sofa!

6 Neil Armstrong on the Moon

For those of us who are old enough to remember the Apollo 11 mission, Neil Armstrong stepping onto the moon’s surface is an unforgettable moment. We seemed to be on the verge of conquering space; science fiction was suddenly real.

In 1961, President Kennedy set the goal of reaching the moon before the end of the sixties. Considering the available technology, it must have seemed an impossible task to most people. But the men and women of NASA buckled down to the job and delivered spectacularly.

When Neil Armstrong took his first steps on the face of the moon, he stated, “That’s one small step for man. One giant leap for mankind.” Neil Armstrong himself actually said the above was a misquote, reported on every news channel of the time. He later stated, “That’s one small step for a man…”. But, given that Armstrong’s transmission was from 238,900 miles away, I think we can forgive the media this once!

For many years, the Soviets claimed they had never been interested in a manned mission to the moon and said that the U.S. was wasting money and taking risks for theatrical reasons. In fact, we now know that they did want to beat the United States there and lost out.

5 Challenger Explodes

On January 28, 1986, the space shuttle Challenger set off on its mission from the Cape Canaveral launch facility in Florida. It reached a height of 46,000 feet before its solid rocket booster exploded and blew the whole assembly apart. The crew of seven was killed. Although there is evidence that some survived the initial explosion, there was no way of escaping the disintegrating craft.

A tragedy under any circumstances, but this was perhaps made even worse by the fact that the Challenger was carrying a school teacher, Christa McAuliffe, and many of her schoolchildren were eagerly watching the launch.

Two o-ring seals had failed; they were made brittle by unseasonably cold weather at the launch pad. Pressurized gas leaked out, a propellant tank was damaged, and the contents ignited. The spacecraft twisted, and aerodynamic forces ripped it apart. The crew had no chance.

Space programs carry risks, and, unfortunately, accidents happen. We learn a little more from each one.

4 The Simpsons’ First Appearance

On April 19, 1987, The Tracey Ullman Show ran a short featuring some new animated characters. It was the start of a phenomenon that is still going strong today. The intelligent scripts, the well-defined characters, and the irreverent humor redefined animation.

The Simpsons appeals to young and old alike. Some may disapprove and believe that it’s not suitable for young children. It’s certainly true that The Simpsons is not very politically correct, that Homer drinks too much beer, and isn’t the brightest of men. But the family is strong and united. The values that the program promotes are values that we all should share. Love and loyalty are not the least among them.

A poll in Great Britain revealed that The Simpsons were more popular than the British royal family. A show that seems to be very American is widely watched all over the world. It hits all the right notes.

3 Breaching the Berlin Wall

After the Second World War, military power was divided into two camps. The West was led by the United States, and the East by the Soviet Union. The relationship between the two powers had moments of relative calm but many more moments of high tension. With both having enough nuclear weapons to wipe us all out, it’s no wonder that people often worried about the future.

When the Soviet system collapsed—demonstrated by the fall of the Berlin Wall in 1989—it seemed that a new era might be possible. Most who witnessed East Germans freely crossing into West Germany believed that they were seeing something truly groundbreaking on live TV, and they truly were.

The political map is different now, but perhaps, things haven’t worked out as we hoped. In many ways, when there were only two players on the stage, things were simpler. The world looks a lot more complicated these days.

2 A Long Time Coming

The American drama series Dawson’s Creek ran for six seasons starting in 1998. The popular show followed the fortunes of Dawson and his pal, Joey, as they went through their teenage years together. The clip we have here aired in 2000 and shows the first ever gay male kiss to be aired on television. Women were a little ahead—LA Law had shown two women kissing in 1991.

Television producers want to make their shows as popular as possible and know that their potential viewers have a wide range of beliefs and opinions. They were sometimes reluctant to take risks and sometimes ended up behind the times.

The rise of streaming platforms and greater choices for viewers has led producers to be a little more adventurous.

1 Elizabeth at Rest

On September 19, 2022, Britain stood a standstill in recognition of the funeral of Queen Elizabeth II. Some estimates suggest that around 4.1 billion people saw the event. If this is right (and there are some questions about how the figure was calculated), then over half the world’s population watched—making it the biggest live event ever on television.

We started our list with the pomp of a coronation and closed it now with the solemnity of a funeral. In her 70 years on the throne, Elizabeth saw many changes. Television has reflected those changes and, sometimes, helped spark them.
