A mysterious metal-rich asteroid called Psyche has been baffling scientists for over two centuries, and its true origin remains one of the biggest unanswered questions in planetary science. Is it the exposed core of a failed planet, or a chaotic mix of rock and metal forged through countless violent collisions? To find out, researchers simulated how a massive crater near Psyche’s north pole formed, revealing that the asteroid’s internal “porosity” — how much empty space it contains — may hold the key to its secrets.

The James Webb Space Telescope has revealed new details in a bizarre nebula that looks like a brain floating in space. Formed by a dying star, the “Exposed Cranium” nebula shows layered gas and a dark central divide that creates its eerie shape. Webb’s infrared view suggests powerful jets may be shaping the structure. The images capture a brief and dramatic phase in a star’s final evolution.

Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than 10 billion years ago whose light was bent and magnified by a foreground galaxy, creating multiple images through gravitational lensing. Because the light from each image traveled slightly different paths, it arrived at Earth at different times, letting scientists effectively watch different moments of the same cosmic explosion simultaneously.

Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s measured. This faint rotation in the cosmic microwave background could point to entirely new physics, including hidden particles such as axions and clues about dark matter or dark energy.

A redesigned cancer immunotherapy is showing striking early results after decades of disappointment with similar drugs. Researchers engineered a more powerful CD40 agonist antibody and changed how it’s delivered—injecting it directly into tumors instead of into the bloodstream. In a small clinical trial of 12 patients with metastatic cancers, six saw their tumors shrink and two experienced complete remission.

A new UCLA Health study suggests that long-term exposure to the pesticide chlorpyrifos may dramatically raise the risk of Parkinson’s disease. Researchers found that people living in areas with sustained exposure had more than 2.5 times the likelihood of developing the disorder. Lab experiments reinforced the finding: animals exposed to the chemical developed movement problems, lost dopamine-producing neurons, and showed the same toxic protein buildup seen in Parkinson’s patients.

New research shows that sourdough fermentation does more than make bread rise—it transforms wheat fibers in unexpected ways. Scientists found that enzymes already present in wheat, activated by the sourdough’s acidic environment, break down key fibres called arabinoxylans. This process may influence the bread’s texture, digestibility, and flavor. Some microbes even create buttery or subtly sweet notes that give sourdough its distinctive taste.

The distinctive smell of ancient mummies is helping scientists decode the secrets of Egyptian mummification. By analyzing tiny traces of chemicals in the air around mummy samples, researchers identified dozens of compounds linked to oils, resins, beeswax, and bitumen used during embalming. The chemical clues reveal that mummification grew increasingly complex over thousands of years.

Scientists have discovered that cells can sense far beyond the surfaces they touch. While individual cancer cells can probe about 10 microns ahead by tugging on surrounding collagen fibers, clusters of normal epithelial cells can combine forces to detect layers as far as 100 microns away. This long-range “depth sensing” helps cells decide where to migrate. Understanding how it works could reveal new targets to stop cancer from spreading.

A new detection method called “Jerk” could dramatically improve how scientists forecast volcanic eruptions. By using a single broadband seismometer, the system can detect extremely subtle ground movements caused by magma pushing underground—often hours before an eruption begins. Tested for more than a decade at the Piton de la Fournaise volcano on La Réunion, the tool successfully predicted 92% of eruptions between 2014 and 2023, sometimes giving up to eight hours of warning.

Astronomers have discovered the brightest fast radio burst ever detected and traced it to a nearby galaxy using a new network of CHIME Outrigger telescopes. The flash, nicknamed RBFLOAT, lasted only a fraction of a second but briefly outshone every other radio source in its galaxy. Follow-up observations with the James Webb Space Telescope spotted a faint infrared signal at the same location. The burst’s unusual behavior—showing no signs of repeating—may challenge current ideas about what causes these mysterious cosmic flashes.

New research suggests Mars may have remained habitable much longer than scientists once thought. Ancient sand dunes in Gale Crater appear to have been soaked by underground water billions of years ago, leaving behind minerals that can preserve signs of life. Even after surface water disappeared, subsurface flows may have created protected environments for microbes. These hidden habitats could be key targets in the ongoing search for past life on Mars.

When the Asian financial crisis sent rice prices soaring in Indonesia in the late 1990s, the shock didn’t just strain household budgets—it left lasting marks on children’s bodies. Researchers from the University of Bonn found that kids exposed to the food price surge were more likely to experience stunted growth and, years later, a higher risk of obesity. The findings suggest that during crises, families often maintain calorie intake but cut back on nutrient-rich foods, creating hidden nutritional deficiencies that disrupt healthy development.

Scientists studying crops irrigated with treated wastewater discovered that trace pharmaceuticals often collect in plant leaves. Tomatoes, carrots, and lettuce absorbed medications such as antidepressants and seizure drugs during the experiment. However, the edible portions of tomatoes and carrots contained much lower levels than the leaves. The findings help researchers understand how crops process contaminants as wastewater reuse becomes more common.

The asteroid impact that wiped out the dinosaurs didn’t keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years—and possibly in under 2,000 years—after the disaster. Scientists uncovered this rapid rebound by using a rare isotope marker to more accurately measure time in ancient sediments. The discovery suggests life recovered far faster than previously thought.

A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that TDP43 controls a key DNA repair process, but when the protein becomes imbalanced, the repair system can spiral out of control, harming neurons and destabilizing DNA. The team also discovered that high levels of the protein are linked to increased mutation rates in cancer. The discovery places TDP43 at the center of both neurodegeneration and cancer biology.

Hidden in volcanic lakes and deep-sea vents, scientists have discovered tough new DNA-binding proteins built to survive extreme conditions. After scanning huge genetic databases, researchers found molecules that remain stable under heat, salt, and harsh chemistry. One of these proteins significantly improved rapid LAMP diagnostic tests, making them faster and more sensitive. The discovery could help create better tools for detecting infectious diseases.

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that activate division genes. Using cryo-electron microscopy, scientists captured this interaction in remarkable detail. The mechanism appears to be widespread across bacteria, offering a new window into how microbes regulate growth.

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a frozen desert. NASA’s twin-spacecraft ESCAPADE mission aims to watch this process in action by measuring how the solar wind interacts with Mars’ fragile magnetic environment. The findings could reveal how Mars lost its habitability—and help prepare humans for future missions there.

NASA’s Curiosity rover is investigating strange spiderweb-like ridges on Mars that may reveal a hidden chapter of the planet’s watery history. These “boxwork” formations likely formed when groundwater flowed through cracks in the rock, leaving minerals that hardened into ridges while surrounding material eroded away. New chemical analyses of drilled rock samples show minerals linked to water activity.

Spiders and insects may not be fan favorites, but they are vital to the health of ecosystems—and scientists barely know how they’re doing. Researchers found that nearly 90% of North America’s insect and arachnid species have no conservation status, leaving their fate largely unknown. Even more striking, most states don’t protect a single arachnid species. The study warns that these overlooked creatures are essential to planetary health and urgently need better monitoring and protection.

Hair may grow in a completely different way than scientists once believed. Instead of being pushed out from the root, new research shows that moving cells inside the follicle actually pull the hair upward like a microscopic motor. Advanced 3D imaging revealed a spiral movement of cells that generates this force. The finding could change how scientists study hair loss and design future treatments.

Scientists may have finally solved the mystery of strange plume-like structures hidden deep inside the Greenland ice sheet. New research suggests they form through thermal convection—slow, swirling motions driven by temperature differences inside the ice. This means the deep ice could be far softer than scientists once believed. Understanding this hidden movement could improve predictions about how Greenland’s ice sheet behaves in a warming world.

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more environmentally friendly. The breakthrough was uncovered unexpectedly during a failed laboratory experiment.

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic switches, controlling when and how genes are activated. These sequences, known as conserved non-coding sequences (CNSs), were detected using a new computational tool called Conservatory.

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and normalized intestinal movement. The study also found that people with IBS have lower levels of one of these bacteria. The discovery suggests gut microbes could become a powerful new target for treating digestive disorders.

A newly identified Australian tree has been dubbed the “zombie” tree because it’s alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow disease-free seedlings in protected locations. Their hope is that a future generation may evolve resistance and bring the species back from the brink.

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, water, and even household dust—could trigger inflammation and damage in the brain through multiple biological pathways. Scientists estimate adults may consume about 250 grams of these particles each year, and some can accumulate in organs including the brain.

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions that improve fuel mixing and lower combustion temperatures. Studies show this technique can slash nitrogen oxide and soot emissions by more than 60% while sometimes even improving engine efficiency. Because it works in existing engines without redesign, it could provide a quick path to cleaner diesel use.

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of Sun-like stars billions of years ago. The journey may have carried the solar system away from the galaxy’s crowded center into a calmer region where life could eventually emerge.

In medieval Denmark, people could pay for more prestigious graves closer to the church — a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something unexpected: even people with stigmatized diseases like leprosy were buried in these high-status spots. Instead of excluding the sick, many communities appear to have treated them much like everyone else.

Gold and other heavy elements are born in some of the universe’s most violent events—but scientists still struggle to understand the nuclear steps that create them. Now, nuclear physicists have uncovered three key discoveries about how unstable atomic nuclei decay during the rapid neutron-capture process, the chain reaction responsible for forging elements like gold and platinum.

Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting sugars and creating tiny fluid currents that carry them forward — a newly identified behavior researchers call “swashing.” In another study, a different group of bacteria was shown to control its movement using a microscopic molecular “gearbox” that can reverse direction like a biological snowmobile.

A study from Kobe University has uncovered a surprising partnership between Japanese red elder plants and Heterhelus beetles. The beetles pollinate the flowers but also lay eggs inside the developing fruit. The plant responds by dropping many of those fruits, yet the larvae survive by escaping into the soil. The discovery suggests that fruit drop is not punishment but a compromise that keeps the plant–insect relationship stable.

Researchers have uncovered a universal pattern showing how temperature affects life on Earth. Across thousands of species—from microbes to reptiles—performance rises gradually with warming until an optimal temperature is reached, after which it drops sharply. Although each species has its own preferred temperature range, they all follow the same underlying curve. This surprising constraint suggests evolution may have limited room to help species cope with rapid climate warming.

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the event GW200105, contradicts the long-held expectation that such pairs settle into nearly perfect circles before collision. The eccentric orbit suggests the system likely formed in a chaotic stellar environment with strong gravitational interactions.

Researchers have discovered that hedgehogs can hear ultrasound, a surprising ability that could help protect them from cars. Since road traffic kills large numbers of hedgehogs, scientists believe ultrasonic repellents might be used to steer them away from danger. The animals’ ears appear specially adapted for detecting high-frequency sounds. If the idea works, cars could one day emit signals that warn hedgehogs before it’s too late.

Decades of data from over 80,000 great tits reveal that extreme weather can shape the fate of baby birds. Cold snaps soon after hatching and heavy rain later in development shrink nestling body mass and reduce survival odds. But moderate warm spells can actually help chicks grow by boosting insect activity and feeding opportunities. Birds that breed earlier in the season seem better protected from these weather shocks.

Scientists have discovered that a rare “mirror-image” version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most anticancer treatments that harm normal tissues, this molecule—called D-cysteine—is taken up mainly by some cancer cells through a specific transporter on their surface. Once inside, it shuts down a crucial mitochondrial enzyme that cancer cells rely on to produce energy and maintain DNA, effectively halting their growth.

Researchers have discovered a surprising change in how cells produce energy in people with depression. Brain and blood cells in young adults with major depressive disorder produced more energy molecules at rest but had trouble increasing energy production when needed. Scientists believe this imbalance may contribute to symptoms such as fatigue and low motivation. The finding could help pave the way for earlier diagnosis and more personalized treatments.

A new study suggests Alzheimer’s disease may be detectable through subtle shape changes in proteins found in the blood. Researchers discovered that structural differences in three blood proteins closely track the progression of the disease. By analyzing these changes in more than 500 people, the team was able to distinguish healthy individuals from those with mild cognitive impairment or Alzheimer’s with impressive accuracy. The approach could help move diagnosis and treatment to earlier stages.

Scientists have grown chickpeas in simulated moon soil, offering a promising step toward farming on the lunar surface. Researchers mixed moon-like regolith with worm-produced compost and helpful fungi that protect plants from toxic metals. The combination allowed chickpeas to grow and produce a harvest in soil that normally cannot support plant life. Scientists now need to confirm the crops are safe and nutritious for astronauts.

Scientists at Curtin University have uncovered a new way to read the deep history of Earth’s landscapes using microscopic zircon crystals from ancient beach sands. These incredibly durable minerals trap traces of krypton gas created when cosmic rays strike them at Earth’s surface, effectively turning each crystal into a “cosmic clock.” By measuring that krypton, researchers can determine how long sediments lingered near the surface before burial, revealing how landscapes eroded, shifted, and stabilized over millions of years.

Scientists have uncovered new clues about some of Earth’s earliest fish, shedding light on the ancient origins of vertebrates that eventually moved onto land. By reanalyzing mysterious fossils from Australia’s famed Gogo Formation and studying a newly reconstructed 410-million-year-old lungfish skull from China, researchers are revealing how these primitive creatures evolved.

Astronomers have caught what may be a rare cosmic catastrophe unfolding 11,000 light-years away. A seemingly ordinary sun-like star suddenly began flickering wildly, puzzling scientists until they realized the strange dimming was caused by vast clouds of hot dust and debris drifting across the star. The most likely explanation is a violent planetary collision—two worlds smashing together and scattering glowing material throughout the system.

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared in a superluminous supernova about a billion light-years away and revealed clues about what’s happening deep inside the blast.

A rare encounter with a juvenile great white shark caught by fishermen in April 2023 has reignited scientific interest in the mysterious population of these apex predators in the Mediterranean Sea. By reviewing records spanning more than 160 years, researchers found that great whites still appear sporadically in Spanish Mediterranean waters, suggesting the population—though elusive and declining—has not vanished. The discovery of a young shark raises an intriguing possibility: these legendary predators may still be reproducing in the region.

Researchers exploring Uganda’s Kibale National Park have discovered seven new species of frog-like leafhoppers. The tiny insects, named for their frog-shaped bodies and powerful jumping legs, are so similar in appearance that scientists must examine microscopic anatomical details to tell them apart. The find represents the first new African species of this group recorded since 1981. One species was named in honor of the scientist’s late mother.

A newly developed antibiotic called EVG7 could offer a powerful new way to stop Clostridioides difficile, a dangerous gut bacterium that often returns after treatment. In mouse studies, researchers found that even a very small dose of EVG7 was highly effective at clearing the infection and preventing it from coming back. Unlike many current antibiotics, which wipe out large portions of the gut microbiome, EVG7 appears to spare beneficial bacteria that naturally help keep C. difficile in check.

Coenzyme A, a molecule derived from vitamin B5, is vital for metabolism throughout the body. Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular powerhouses was unclear. Yale researchers have now identified the transport system that moves CoA into mitochondria, solving a long-standing biological puzzle. The discovery could help researchers better understand diseases linked to metabolic dysfunction and mitochondrial problems.

Scientists have developed a promising new approach to treating Alzheimer’s disease by turning ordinary brain cells into powerful plaque-clearing machines. Instead of requiring frequent antibody infusions like current therapies, the experimental treatment uses genetically engineered astrocytes — abundant support cells in the brain — that are equipped with a CAR “homing device” similar to those used in cancer immunotherapy.

Researchers have uncovered a molecular trick used by hornwort plants that could help future crops capture carbon dioxide more efficiently. A unique protein feature called RbcS-STAR causes the key photosynthesis enzyme Rubisco to cluster into dense compartments, helping it work more effectively. When scientists added this feature to other plants, Rubisco reorganized in the same way. The finding raises the possibility of engineering more efficient photosynthesis into major crops.

As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, iron-limited conditions by using iron more efficiently. Because these microbes control key nitrogen reactions that support marine life, their adaptability could help sustain ocean productivity. In a warming world, they may play an even bigger role in shaping marine nutrient cycles.

A long-running debate about the Silverpit Crater beneath the North Sea has finally been resolved. Scientists now confirm it formed when a roughly 160-meter asteroid struck the seabed about 43–46 million years ago. New seismic imaging and rare shocked minerals in rock samples provided the crucial proof. The impact would have sent a massive plume skyward and unleashed a tsunami over 100 meters (330 feet) high.

THC doesn’t just blur memories—it can create new ones that never happened. In a controlled experiment, cannabis users were much more likely to recall words that were never shown and struggled with tasks like remembering to do something later. Researchers found that THC disrupted many different memory systems at once. Surprisingly, moderate doses caused memory problems similar to higher doses.

Researchers have developed a high-tech system that rapidly scans ants and converts them into detailed 3D models. Using a synchrotron accelerator, X-ray imaging, robotics, and AI, the team scanned 2,000 specimens in just a week and produced models of 800 species. The images reveal microscopic anatomy that was previously difficult to study. The growing Antscan database could become a powerful digital library of biodiversity.

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While studying the paths of light rays and moving objects, Hamilton noticed a striking mathematical similarity between them and used it to develop a powerful new framework for mechanics. At the time, it seemed like a clever analogy—but decades later, as scientists uncovered the strange wave-particle nature of light and matter, Hamilton’s insight took on new meaning.

A nearly complete dinosaur skeleton discovered in Patagonia is helping scientists crack the mystery of alvarezsaurs, a bizarre group of bird-like dinosaurs. The fossil of Alnashetri cerropoliciensis reveals that these animals became tiny before developing their later specialized features, such as stubby arms and ant-eating adaptations. Weighing under two pounds, the dinosaur is one of the smallest known from South America.

Scientists studying Mars may have uncovered a brand-new mineral hidden in the planet’s ancient sulfate deposits. By combining laboratory experiments with orbital data, researchers identified an unusual iron sulfate—ferric hydroxysulfate—forming in layered deposits near the massive Valles Marineris canyon system. The mineral likely formed when sulfate-rich deposits left behind by ancient water were later heated by volcanic or geothermal activity, transforming their chemistry.

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental quantum fields that fill all of space remain, carrying a small but real amount of energy known as vacuum energy, or dark energy. While this energy is overwhelmed by matter in galaxies and clusters, in the deep emptiness of cosmic voids it becomes dominant.
