From the Pampas to Patagonia, DNA reveals South America's human history
A new genetic study shows that cultural diversity in the so-called Southern Cone—the roughly triangular southernmost part of South America—was strongly influenc...
Climate and competition alone cannot explain Neanderthal extinction, study finds
A new modeling study suggests that greater connectivity between groups may have given Homo sapiens the edge over Neanderthals. Why Neanderthals went extinct and...
What we lose when AI does our shopping
Americans spend a remarkable amount of time shopping—more than on education, volunteering or even talking on the phone. But the way they shop is shifting dramat...
What if humans could regrow tissue? New study moves science closer
For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can...
Do polysaccharide-degrading enzymes also help build polysaccharides?
Most of the carbon fixed by plants through photosynthesis is ultimately stored in the cell wall, primarily in the form of polysaccharides such as cellulose, xyl...
Brazil unearths a bizarre beaked reptile with a trans-Atlantic prehistoric link
Paleontologists from the Federal University of Santa Maria (UFSM) have published a new study in the scientific journal Royal Society Open Science, in which they...
Molecular chains unlock atomically precise nanoribbons for next-generation electronics
Scientists have developed a unique way to build electronic components so small they are made from chains of individual molecules—creating a toolbox to help buil...
Mozambique 'sky island' expeditions found four new species of chameleon that are already at risk from forest loss
Tropical rainforests are known for their unique biodiversity, with species found nowhere else on Earth. But nearly 30% of tropical rainforest has been destroyed...
Machine learning helps detect roars from lion collars without recording actual audio
Roaring over long distances is a key behavior of lions. They communicate within prides as well as with other animals using distinct sequences of moans and grunt...
What wild honey from the Philippine jungle reveals about biodiversity
In the Philippines, Indigenous communities have been harvesting wild honey for centuries. A new chemical analysis of this honey now provides insights into the b...
How earthquakes stop: Near-fault records uncover overlooked phase
While analyzing strong-motion data close to fault lines, a group of researchers at Kyoto University noticed something unexpected: a negative phase in the wavefo...
More than 600,000 seabirds killed in single marine heat wave
Ocean temperatures are rising around the world—and marine wildlife are feeling the heat. New research reveals that almost two-thirds of a million seabirds were...
