MIT engineers have developed injectable “mini livers” designed to help support people whose failing livers can no longer perform essential jobs. Instead of replacing the damaged organ, the approach injects liver cells together with tiny hydrogel spheres and…

Cancer is becoming an even larger global health threat, with nearly 21 million people diagnosed and 9.8 million dying from the disease in 2024. New estimates suggest about 1 in 5 people worldwide will develop cancer during their lifetime, while cases could…

A more realistic quantum model has revealed evidence that strange, nearly immobile quasiparticles called fractons could exist in solid materials. Their inability to move freely could make them promising building blocks for unusually robust quantum information…

Scientists have found evidence that some gut bacterial populations can spread rapidly between people and across continents, suggesting the microbiome may be more transmissible than previously thought. The research also revealed hidden bacterial groups associated…

A large study of nearly 74,000 men suggests that long-term use of tadalafil, best known as Cialis, may be linked to a higher risk of glaucoma and other eye pressure problems. Men prescribed the drug for urinary symptoms caused by an enlarged prostate were…

A rediscovered memoir reveals that celebrated War of 1812 veteran Shadrack Byfield was far more rebellious and troubled than history has portrayed, battling chronic pain, poverty, authorities, and even rivals at his local chapel. The soldier who buried his…

Could math help explain why some relationships survive life’s inevitable stresses while others slowly fall apart? Researchers have spent decades developing mathematical models that treat romantic feelings as changing systems, revealing patterns in attraction…

A chemical commonly used in dry cleaning and found in some household products may be an overlooked threat to liver health. Researchers found that people with detectable levels of tetrachloroethylene (PCE) in their blood were three times more likely to have…

A surprising immune system signal may help explain why zebrafish can regenerate damaged spinal cords so effectively. Researchers found that certain neutrophils release Il-4, which calms harmful inflammation and allows injured nerve fibers to grow again. Without…

A critically endangered roloway monkey has given birth just months after surgeons performed an unusual operation that saved her foot from amputation. Her new daughter, Lagertha, is an important addition to a species believed to number fewer than 2,000 in…

Starting statins soon after a type 2 diabetes diagnosis may do more than protect the heart. In a nationwide Danish study of more than 132,000 people, those who began statin treatment within a year of diagnosis had a 15% lower relative risk of developing dementia…

Researchers have found a potential way to attack prostate cancers that evade treatment by changing their cellular identity. Combining two types of drugs reversed many of these changes and sharply slowed tumor growth in preclinical experiments, offering a…

The extinct “American cheetah” was not really a cheetah at all, but a puma relative with an unexpectedly flexible lifestyle. Fossils from the Yukon suggest northern populations survived partly by eating fish, possibly including salmon, while southern cats…

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s quantum wave so that one part was held in place while the…

Scientists have identified a giant new dinosaur from Brazil that reached about 20 meters long and lived 120 million years ago. Its surprising evolutionary ties to a Spanish dinosaur suggest its ancestors crossed ancient land connections between Europe, Africa…

Semaglutide, the drug behind Ozempic and Wegovy, may have benefits that extend well beyond weight loss and diabetes. In a large Swedish study of nearly 15,000 people with bipolar disorder, its use was linked to a 21% lower risk of psychiatric hospitalization.…

More than 1,200 genetic variants have been linked to the Big Five personality traits, and many of the same variants are also associated with health, longevity, careers, income, and everyday habits. The findings reveal a surprisingly wide genetic connection…

Researchers discovered that combinations of toxin-blocking proteins naturally found in rattlesnake blood can powerfully neutralize venom from several dangerous snake species. In lab tests, the mixtures were about 10 times more potent than a current commercial…
