Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis (DMTA) has now been used to infer the feeding habits of large theropods, including Allosaurus and T. rex. By taking 3D images of individual teeth and analyzing the pattern of marks scratched into them, researchers could...

The biochemical process by which cyanobacteria acquire nutrients from rocks in Chile's Atacama Desert has inspired engineers at the University of California, Irvine to think of new ways microbes might help humans build colonies on the moon and Mars.

In rural Bangladesh, areas with high levels of arsenic contamination in drinking water, compared to areas with less contamination, have a higher prevalence of antibiotic-resistant Escherichia coli in both water and child stool samples, according to a new study.

Modern Papuans' immune system likely evolved with a little help from the Denisovans, a mysterious human ancestor who interbred with ancient humans, according to a new study.

Argentine ants have been able to displace native ant species in large part because of their aggressive foraging for sugar and other carbohydrates. However, when they've been deprived of food and competitors are present, they significantly limit their foraging activity instead of vigorously pursuing food. On the whole, this strategy...

Researchers have been studying the effects of the sudden decrease in global temperatures that occurred about 8,200 years ago, the so-called 8.2-kiloyear event, with the help of mineral deposits present in White Moon Cave in Northern California. New indications show that oscillations between extreme wetness and aridity in California were...

Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves -- and moving towards dangerous wildfires and warmer temperatures, says one of the largest studies of U.S. migration and natural disasters. These results are concerning, as wildfire and rising temperatures are projected to worsen with climate...

The group with the world's simplest animals -- tiny blob-like life forms with no organs and just a few cell types -- finally has a fleshed-out family tree. The study comes more than 100 years after the discovery of these ameboid animals called placozoans and represents the first -- and...

A new study analyzing stone tools from southern China provides the earliest evidence of rice harvesting, dating to as early as 10,000 years ago. The researchers identified two methods of harvesting rice, which helped initiate rice domestication.

New research highlights the risks of countries relying on nature-based solutions to achieve net-zero. National climate strategies set out how countries plan to reduce emissions, for example by phasing out fossil-fuel use, to get to net-zero in 2050. The study found, once the bulk of emissions have been reduced, countries...
