| One Tiny Change May Explain How Viruses Jump From Bats to Humans | | 2026-07-07 11:54:01 +00:00
 Scientists found that one tiny genetic change may determine whether a bat virus stays in bats or becomes a human threat. Most infectious disease outbreaks begin when a virus or other pathogen crosses from animals into people. Many scientists believe that is how the COVID-19 pandemic began, with SARS-CoV-2, the virus responsible for COVID-19, originating [...]

| The Secret to Healthy Aging May Be More Protein and More Exercise | | 2026-07-07 11:19:50 +00:00
 A new review suggests that many adults could benefit from more protein and more exercise than current public health guidelines recommend. A growing body of research suggests that the health advice many people follow today may only be enough to prevent deficiency, not help them thrive throughout life. A new perspective paper published in Frontiers [...]

| Scientists Unravel a Century-Old Mystery About Hybrid Male Sterility | | 2026-07-06 21:22:45 +00:00
 A new study identifies a genetic processing failure that leaves hybrid fruit fly males unable to produce sperm. One of evolution’s defining moments occurs when two populations become so genetically different that they can no longer produce fertile offspring together. Even among closely related species that can still mate, their hybrid young often reach adulthood [...]

| These 567-Million-Year-Old Fossils Are Rewriting the Story of Life on Earth | | 2026-07-06 20:37:43 +00:00
 Ancient deep-sea organisms suggest movement, sexual reproduction, and complex animal life began earlier than previously thought. Every animal alive today, from jellyfish to humans, traces its ancestry back to a pivotal moment when complex life first emerged from a world dominated by simple microbes. Yet the fossil record from this evolutionary turning point remains frustratingly [...]

| Scientists Discover 250+ Genes That Could Lead to New Ways To Prevent Melanoma | | 2026-07-06 16:10:23 +00:00
 The world’s largest study of mole genetics identified hundreds of genes tied to melanoma risk, uncovering potential new drug targets and paving the way for more accurate melanoma screening and prevention. Researchers at QIMR Berghofer have identified hundreds of genes involved in the development of both moles and melanoma, a finding that could open the [...]

| This Gut Microbe Could Be the Secret to Staying Strong as You Age | | 2026-07-06 15:25:20 +00:00
 Scientists have identified a gut microbe that appears to be associated with stronger muscles and better fitness, with levels declining as people age. What if some of the microbes living in your gut could help determine how strong your muscles are? New research suggests that one bacterial species, Roseburia inulinivorans, may play an important role [...]

| The Spider-Like Creatures Helping Scientists Decode the Origins of Fatherhood | | 2026-07-06 11:47:40 +00:00
 Citizen science helped reveal that parental care in harvestmen has evolved repeatedly across their evolutionary history. Citizen science observations from the popular platform iNaturalist have helped clarify how parental guarding behavior evolved in harvestmen, according to research published in the Zoological Journal of the Linnean Society. By combining almost 30 years of fieldwork with iNaturalist [...]

| Scientists Baffled by a Sudden Reversal Deep Inside Earth’s Core | | 2026-07-06 11:02:34 +00:00
 A surprising reversal in molten iron flow beneath the Pacific is giving scientists a sharper view of how Earth’s magnetic field evolves. Earth’s magnetic field, the invisible shield that protects the planet from charged particles streaming from the Sun, is powered by a churning ocean of molten iron hidden thousands of kilometers beneath our feet. [...]

| Scientists Discover a Spider That Catapults Ants Into Its Web | | 2026-07-06 03:04:28 +00:00
 This nocturnal rainforest spider has evolved an unusually specialized hunting strategy, using a silk-powered snare to target a single ant species and launch its prey into the air with remarkable speed and force. In the rainforest near Cooktown, a green tree ant can trigger its own ambush. The ant bites what looks like a small [...]
