For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed huge amounts of material shortly before it exploded, likely due to interaction with a nearby companion star. This discovery gives scientists a new tool to rewind the clock on stellar deaths. It also shows that some... Read more ›

What looked like a pearl necklace on a tiny spider turned out to be parasitic mite larvae. Scientists identified the mites as a new species, marking the first record of its family in Brazil. The larvae attach to juvenile spiders and feed on lymph through a weak spot in the spider’s body. The discovery came from long-stored specimens, suggesting many more species remain hidden in collections. Read more ›

A sweeping scientific review highlights wild blueberries as a standout food for cardiometabolic health. The strongest evidence shows improvements in blood vessel function, with encouraging signs for blood pressure, cholesterol, blood sugar, gut health, and cognition. Researchers suggest these benefits may kick in within hours—or build over weeks—thanks to the berries’ unique mix of polyphenols and fiber. Read more ›

A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, which helps explain why infections are so hard to treat. The discovery could reshape efforts to develop drugs that finally eliminate the parasite for good. Read more ›

Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting this “exercise sensor,” scientists believe they could create drugs that mimic exercise at the molecular level. The approach could protect fragile bones in people who are unable to stay active. Read more ›

Asthma may not be driven by the molecules scientists have blamed for decades. Researchers have identified “pseudo leukotrienes,” inflammation-triggering compounds formed by uncontrolled free-radical reactions rather than normal enzymes. These molecules were found at much higher levels in people with asthma, closely tracking how severe their symptoms were. The finding hints at a new way to treat asthma by preventing the inflammatory spark instead of blocking its aftermath. Read more ›

A long-term study found that while a ketogenic diet prevented weight gain, it also triggered major metabolic problems. Mice developed fatty liver disease, abnormal blood fats, and an impaired ability to control blood sugar—especially after reintroducing carbohydrates. Male mice were hit hardest, showing severe liver damage. The results suggest keto’s benefits may come with hidden risks over time. Read more ›

Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective programs, certain metabolic changes can temporarily slow neurodegeneration—hinting at new ways to help the brain defend itself. Read more ›

Quantum technology has reached a turning point, echoing the early days of modern computing. Researchers say functional quantum systems now exist, but scaling them into truly powerful machines will require major advances in engineering and manufacturing. By comparing different quantum platforms, the study reveals both impressive progress and steep challenges ahead. History suggests the payoff could be enormous—but not immediate. Read more ›

Bright white rocks spotted by NASA’s Perseverance rover are rewriting what we thought we knew about ancient Mars. These aluminum-rich clays, called kaolinite, usually form on Earth only after millions of years of heavy rainfall in warm, humid environments—conditions similar to tropical rainforests. Their presence on today’s cold, dry Mars suggests the planet once had abundant rain, flowing water, and possibly lush oases long ago. Even more puzzling, the rocks... Read more ›

The Ediacara Biota are some of the strangest fossils ever found—soft-bodied organisms preserved in remarkable detail where preservation shouldn’t be possible. Scientists now think their survival in sandstone came from unusual ancient seawater chemistry that created clay “cements” around their bodies after burial. This process captured delicate shapes that would normally vanish. The finding helps clarify how complex life emerged before the Cambrian Explosion. Read more ›

Scientists have found compelling new evidence that humans, not glaciers, brought Stonehenge’s bluestones to the site. Using advanced mineral analysis, researchers searched nearby river sediments for signs glaciers once passed through the area—and found none. That missing signature strongly suggests the stones were intentionally moved by people. How they did it remains a mystery, but ice is now largely ruled out. Read more ›

A large French study tracking more than 100,000 people over a decade has found that higher consumption of certain food preservatives—commonly found in processed foods and drinks—is linked to a modestly higher cancer risk. While many preservatives showed no association, several widely used ones, including potassium sorbate, sulfites, sodium nitrite, and potassium nitrate, were tied to increased risks of overall cancer and specific types such as breast and prostate cancer.

Carbohydrates don’t just fuel the body—they may also influence how the brain ages. A large long-term study found that diets high in fast-acting carbs that rapidly raise blood sugar were linked to a higher risk of dementia. People who ate more low-glycemic foods like fruit, legumes, and whole grains had a noticeably lower risk of Alzheimer’s. The quality of carbs, not just the amount, appears to matter for brain health.

Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that appears just before certain materials become superconductors. Using an ultra-cold quantum simulator, the team found that even when magnetism seems disrupted, subtle and universal magnetic patterns persist beneath the surface. These patterns closely track the temperature at which the pseudogap forms, suggesting magnetism may help set the stage for superconductivity. Read more ›

A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the U.K., researchers found strong evidence that higher body weight can damage brain health over time, especially when it leads to elevated blood pressure. Much of the dementia risk appeared to be tied to vascular damage in... Read more ›

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon atoms to slip through the metal. This slows diffusion at the atomic level and alters steel’s internal structure. The insight could lead to more efficient, lower-energy ways to make stronger steel. Read more ›

Our genome isn’t as peaceful as it looks—some DNA elements are constantly trying to disrupt it. Scientists studying fruit flies discovered that key proteins protecting chromosome ends must evolve rapidly to counter these internal threats. When these proteins fall out of sync, chromosomes fuse and cells die. The work reveals how essential biological systems survive by constantly reinventing themselves. Read more ›

When materials become just one atom thick, melting no longer follows the familiar rules. Instead of jumping straight from solid to liquid, an unusual in-between state emerges, where atomic positions loosen like a liquid but still keep some solid-like order. Scientists at the University of Vienna have now captured this elusive “hexatic” phase in real time by filming an ultra-thin silver iodide crystal as it melted inside a protective graphene...

Astronomers may have finally cracked one of the universe’s biggest mysteries: how black holes grew so enormous so fast after the Big Bang. New simulations show that early, chaotic galaxies created perfect conditions for small “baby” black holes to go on extreme growth spurts, devouring gas at astonishing rates. These feeding frenzies allowed modest black holes—once thought too puny to matter—to balloon into monsters tens of thousands of times the... Read more ›
