Deep ocean sand analysis may predict how far Earth’s climate will shift
16+ hour, 20+ min ago (641+ words) Stanford researchers analyzed global seafloor data from an ancient cooling era, expecting thick sand deposits, but found almost no sand across all seven continents, defying standard models. When a Stanford team went looking for sediment that should have blanketed the…...
Earth’s moon may have formed nearly whole just hours after a giant crash
16+ hour, 39+ min ago (504+ words) New simulations suggest the moon may have formed almost instantly after a giant impact, not slowly from a debris disk....
Hungry dogs are more likely to sniff out the wrong scent
21+ hour, 42+ min ago (1003+ words) Hungry dogs made more false alarms, while breakfast helped them reject wrong smells without reducing target detection accuracy. Dogs can find odors that people would never notice, which is why scent detection is useful in jobs ranging from conservation to…...
Amazon climate extremes are surging fastest in unexpected places
20+ hour ago (1075+ words) Climate extremes are intensifying fastest in an unexpected part of the Amazon, where extreme dry-season temperatures are rising far faster than averages. For years, the story of Amazon climate change centered on the south, the region hit hardest by deforestation…...
One small change in walking helped humans conquer the world
20+ hour, 46+ min ago (978+ words) Humans consistently walk heel-first, a unique walking style that saves energy but creates higher impact forces on bones and joints. Walking is so familiar that the first moment of each step rarely gets much attention. Humans normally place the heel…...
This ‘living dinosaur’ survives up to 427 years and rank among the world’s longest-lived vertebrates
21+ hour, 7+ min ago (913+ words) New research suggests lake sturgeon may live for centuries, reshaping conservation plans for one of the Great Lakes’ rarest fish. Some of the lake sturgeon swimming in the Great Lakes may have been there before the United States existed. That…...
Tears and breast milk contain an ancient weapon against bacteria
21+ hour, 5+ min ago (1023+ words) Researchers reconstructed ancient versions of a bacteria-killing protein found in tears and breast milk, and some were more powerful than the human version. Tears, saliva and breast milk all carry a protein that holds iron away from bacteria, which need…...
Bats live remarkably long lives, and their genes reveal why
22+ hour, 48+ min ago (1076+ words) The genes behind bat lifespan overlap with the genes that handle viruses, and one key immune gene comes in up to three copies. A bigger mammal usually lives longer, and bats are a striking exception. Among the mouse-eared bats, body…...
El Niño is stronger now than at any point in the last thousand years
1+ day, 14+ hour ago (1028+ words) Drilled cores from Galápagos coral carry an ocean temperature record back to the year 1000, and recent decades break the pattern. When the tropical Pacific warms every few years, the weather turns strange thousands of miles away. Direct measurements of that…...
Brain cells that protect nerve fibers can turn harmful with age
1+ day, 11+ hour ago (943+ words) A surplus of insulating brain cells, low on one protective protein, tracked the steepest cognitive decline in adults followed since childhood. After 70, memory and quick thinking slow down for most people, and the usual explanation is that the brain’s wiring…...
