Scientists have discovered that unusually small cancer cells carrying extra chromosomes can be far more aggressive than larger ones, growing faster, spreading more readily, and resisting common treatments. The surprising finding could help explain why some tumors are especially dangerous and provide a new way to predict cancer outcomes.
The fight for survival in the forest is fierce: light, water and nutrients are all limited. This is particularly true in "mast years"ātimes when trees and shrubs produce an unusually large crop of fruits, nuts or seeds. Then the race for growth is on. But can differences in height between trees in their first year of life make a difference to their future, even if these differences are just one or two centimeters (0.4 or 0.8 inches)?
Physical surroundings affect everything from personal well-being to a neighborhood's safety. A new study from The Ohio State University finds that when it comes to preventing gun violence in a community, green space can help, but its location makes a big difference.
Researchers explored how AI could spread through everyday gadgets. But cybersecurity experts have seen these tricks before
Confident bees work harder to convince their peers of tasty treats
Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts that a rotating object, such as Earth, slightly drags the surrounding spacetime as it rotates, a phenomenon known as frame-dragging.
A rare examination of an Alzheimerās patientās brain revealed that regions cleared of amyloid plaques had remarkably little of the harmful tau buildup associated with memory loss, while neighboring areas showed extensive damage. The discovery suggests that removing amyloid may have lasting protective effects and could help slow Alzheimerās progression, especially when treatment begins early.
Countries highly vulnerable to the phase-out of oil, gas and coal account for just 6% of global economic output, countries in Africa stand to benefit from their vast solar energy potential, and the economic interests of the U.S., Europe and China are affected by climate policy in surprisingly similar ways. A study by the Potsdam Institute for Climate Impact Research (PIK) published in Nature Sustainability now shows, for 169 countries around the world, how the fight against global heating affects national assetsāand what geopolitical challenges and opportunities arise as a result.
New research has revealed an unexpected new mechanism through which the killer fungus Candida auris is resisting antifungal drug treatment. A team led by the University of Exeter and City St George's, University of London, discovered that the fungus creates multiple versions of its entire genome, including mutating a gene that plays a role in cell wall integrity, called "Crazy-one" (CRZ1).
If you're approaching menopause, you are likely being bombarded by online ads for treatments promising relief for everything from hot flashes to brain fog. Some of these therapies have been approved by the Food and Drug Administration (FDA) and have strong evidence to support them ā but one hormone-based treatment that's gaining in popularity has much less science to back its use for menopause.More doctors are writing their menopausal patients prescriptions for testosterone therapy. A 2026 study conducted in the U.S. recorded over 90,000 off-label prescriptions for testosterone to women in 2025, mainly among women ages 45 to 64 and those with diagnoses of menopause. This marked a 58.7% incre...
In the middle of nowhere, a small island emerges in the Atlantic Ocean. This unique territory completely changed in the 19th century thanks to the efforts of two British scientists: Charles Darwin and Joseph Dalton Hooker, researchers who stopped at the British naval base and documented the island during their expeditions.
Strokes are becoming alarmingly common among younger adults, with rates nearly doubling among people ages 20 to 54 over nearly three decades. Researchers found that blocked blood vessels in the brain accounted for much of the increase, while high blood pressure, diabetes, and substance use also became more common among younger stroke patients. Although survival rates have improved, more young adults may now face the lasting consequences of stroke.
