How gene loss and monogamy built termite mega societies
Termites did not evolve complex societies by adding new genetic features. Instead, scientists found that they became more social by shedding genes tied to competition and independence. A shift to monogamy removed the need for sperm competition, while food sharing shaped who became workers or future kings and queens. Together, these changes helped termites build colonies that can number in the millions.View the full article

Ancient tools in China are forcing scientists to rethink early humans
Archaeologists in central China have uncovered evidence that early humans were far more inventive than long assumed. Excavations at the Xigou site reveal advanced stone tools, including the earliest known examples of tools fitted with handles in East Asia, dating back as far as 160,000 years. These discoveries show that ancient populations in the region carefully planned, crafted, and adapted their tools to meet changing environments.View the full article

Late bedtimes are linked to higher heart disease risk
People who naturally stay up late may be putting their hearts under added strain as they age. A large study tracking more than 300,000 adults found that middle-aged and older night owls had poorer overall heart health and a higher risk of heart attack and stroke than those who were active earlier in the day, with the effect especially pronounced in women. Much of this elevated risk appeared to stem from lifestyle factors common among evening types, including smoking and inadequate sleep.View the full article

The early turning point when men’s heart risk accelerates
Men start developing heart disease earlier than women, with risks rising faster beginning around age 35, according to long-term research. The difference is driven mainly by coronary heart disease, not stroke or heart failure. Traditional risk factors explain only part of the gap. The findings suggest earlier screening could help catch problems before serious damage occurs.View the full article

Gray wolves are hunting sea otters and no one knows how
On a remote Alaskan island, gray wolves are rewriting the rulebook by hunting sea otters — a behavior few scientists ever expected to see. Researchers are now uncovering how these coastal wolves adapted to marine hunting, what it means for land–sea ecosystems, and whether this ancient predator–prey relationship is re-emerging as sea otters recover.View the full article

A breakthrough that could make ships nearly unsinkable
Researchers have found a way to make ordinary aluminum tubes float indefinitely, even when submerged for long periods or punched full of holes. By engineering the metal’s surface to repel water, the tubes trap air inside and refuse to sink, even in rough conditions. The technology could eventually be scaled up into floating platforms, ships, or even wave-powered energy systems.View the full article

Scientists find hidden pathways pancreatic cancer uses to spread
Researchers have discovered how pancreatic cancer reprograms its surroundings to spread quickly and stealthily. By using a protein called periostin, the tumor remodels nearby tissue and invades nerves, which helps cancer cells travel and form metastases. This process also creates a tough, fibrous barrier that makes treatments less effective. Targeting periostin could help stop this invasion before it starts.View the full article

A fish that ages in months reveals how kidneys grow old
A fast-aging fish is giving scientists a rare, accelerated look at how kidneys grow old—and how a common drug may slow that process down. Researchers found that SGLT2 inhibitors, widely used to treat diabetes and heart disease, preserved kidney structure, blood vessels, and energy production as the fish aged, while also calming inflammation. The results help explain why these drugs protect kidneys and hearts so reliably in people, even beyond blood sugar control.View the full article

New scan spots heart disease years before symptoms
A new imaging technology called fast-RSOM lets researchers see the smallest blood vessels in the body without invasive procedures. It can detect early dysfunction in these vessels — a quiet warning sign of future heart disease — long before symptoms appear. Unlike traditional risk estimates, it measures real changes happening in the body. The portable system could one day be used in routine checkups to catch heart risks earlier.View the full article

A 20-year-old cancer vaccine may hold the key to long-term survival
Two decades after a breast cancer vaccine trial, every participant is still alive—an astonishing result for metastatic disease. Scientists found their immune systems retained long-lasting memory cells primed to recognize cancer. By enhancing a key immune signal called CD27, researchers dramatically improved tumor elimination in lab studies. The findings suggest cancer vaccines may have been missing a crucial ingredient all along.View the full article

A Trojan horse cancer therapy shows stunning results
Scientists at Mount Sinai have unveiled a bold new way to fight metastatic cancer by turning the tumor’s own defenses against it. Instead of attacking cancer cells head-on, the experimental immunotherapy targets macrophages—immune cells that tumors hijack to shield themselves from attack. By eliminating or reprogramming these “bodyguards,” the treatment cracks open the tumor’s protective barrier and allows the immune system to flood in and destroy the cancer.View the full article

Scientists use AI to crack the code of nature’s most complex patterns 1,000x faster
Order doesn’t always form perfectly—and those imperfections can be surprisingly powerful. In materials like liquid crystals, tiny “defects” emerge when symmetry breaks, shaping everything from cosmic structures to everyday technologies. Now, researchers have developed an AI-powered method that can predict how these defects will form and evolve in milliseconds instead of hours. By learning directly from data, the system accurately maps molecular alignments and complex defect behavior, even in situations where defects merge or split.View the full article

Dermatologists say collagen supplements aren’t the skin fix people expect
Collagen pills sound like a shortcut to younger skin, but solid evidence doesn’t back them up. Higher-quality studies show little benefit, and your body doesn’t absorb collagen in the way ads suggest. Some supplements may even pose safety concerns and lack proper testing. Experts recommend focusing on proven habits like sunscreen, retinoids, and a nutrient-rich diet instead.View the full article

A diabetes drug shows surprising promise against heart disease
An experimental drug once known for helping control type 2 diabetes may also fight heart disease. Researchers found IC7Fc lowered cholesterol, blood fats, and artery-clogging plaques while calming inflammation linked to heart attacks and strokes. Notably, these benefits appeared even without weight loss, suggesting the drug could help lean people at risk of heart disease.View the full article

A simple blood test could spot Parkinson’s years before symptoms
Scientists in Sweden and Norway have uncovered a promising way to spot Parkinson’s disease years—possibly decades—before its most damaging symptoms appear. By detecting subtle biological signals in the blood tied to how cells handle stress and repair DNA, the team identified a brief early window when Parkinson’s quietly leaves a measurable fingerprint.View the full article

Ancient oceans stayed oxygen rich despite extreme warming
Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying expectations. Powerful monsoons and ocean circulation appear to have delayed oxygen loss in this region compared to the Pacific. The discovery suggests future ocean oxygen levels may not follow a simple warming-equals-deoxygenation rule.View the full article

Scientists found a way to cool quantum computers using noise
Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.View the full article

Tiny mammals are sending warning signs scientists can finally read
Small mammals are early warning systems for environmental damage, but many species look almost identical, making them hard to track. Scientists have developed a new footprint-based method that can tell apart nearly indistinguishable species with remarkable accuracy. Tested on two types of sengi, the system correctly identified them up to 96% of the time. It offers a simple, ethical way to monitor ecosystems before they quietly unravel.View the full article

Helping with grandkids may slow cognitive decline
Helping care for grandchildren may offer an unexpected boost to brain health later in life. Researchers found that grandparents who provided childcare scored higher on memory and verbal skills than those who did not. The effect did not depend on how often they helped or the type of care they provided. Being involved as a caregiver itself appeared to matter most.View the full article

Long-term alcohol use linked to a sharp rise in rectal cancer
Drinking heavily over many years is linked to a higher risk of colorectal cancer, especially rectal cancer, according to new research tracking U.S. adults for two decades. People who drank heavily throughout adulthood faced sharply higher risks than light drinkers. Former drinkers did not show increased cancer risk and had fewer precancerous tumors. The results suggest that quitting alcohol may help lower long-term cancer risk.View the full article

Low-Earth orbit is just 2.8 days from disaster
Low-Earth orbit is more crowded—and fragile—than it looks. Satellites constantly weave past each other, burning fuel and making dozens of evasive maneuvers every year just to stay safe. A major solar storm could disable navigation and communications, turning that careful dance into chaos. According to new calculations, it may take just days—not decades—for a catastrophic chain reaction to begin, potentially choking off humanity’s access to space for generations.View the full article

Dark stars could solve three major mysteries of the early universe
JWST has revealed a strange early universe filled with ultra-bright “blue monster” galaxies, mysterious “little red dots,” and black holes that seem far too massive for their age. A new study proposes that dark stars—hypothetical stars powered by dark matter—could tie all these surprises together. These exotic objects may have grown huge very quickly, lighting up the early cosmos and planting the seeds of supermassive black holes.View the full article

Scientists turn tumor immune cells into cancer killers
Scientists at KAIST have found a way to turn a tumor’s own immune cells into powerful cancer fighters—right inside the body. Tumors are packed with macrophages, immune cells that should attack cancer but are usually silenced by the tumor environment. By injecting a specially designed drug directly into tumors, researchers were able to “reprogram” these dormant cells to recognize and destroy cancer.View the full article
