Science, engineering, and discovery — the research and breakthroughs that matter.

In the last few centuries, mammals and other animals have been going extinct at least 100 times faster than they did before humans arrived on the scene. So who will be next? Which species are most likely to survive, and which will die out?

Neanderthals are largely associated with colder climates across Eurasia. But researchers know that both Homo sapiens and Neanderthals moved through nearby Southwest Asia between about 100,000 and 50,000 years ago, and Arabia was a crossroads between Africa, Europe and Asia during

Methane-munching microbes in soil might be more important than previously thought, a new study finds. Soil is an important carbon sink, and scientists are still learning much about the diversity of its microbial communities. They're being uncovered from Arctic soils to desert san

The most prominent difference between human male and female skeletons is the pelvis, which anthropologists often use to determine the sex of ancient remains. Scientists have long believed the human pelvis evolved mainly as a compromise between walking on two legs and giving birth

Hundreds of dead birds are now being reported as the lethal H5N1 strain of bird flu begins to spread across Australia. Government reports show the virus is circulating in resident birds.

Consistent enforcement of rules is more important than the severity of the punishment itself, and children expect adults to treat every member of their group impartially and equally. Moreover, fair punishment brings emotional relief to children, according to research by scientist

As competition between the United States and China intensifies over critical minerals, pressure is mounting to begin exploitation of deep-sea minerals before a code to regulate mining of the seabed in areas beyond national jurisdiction is agreed to.

UC San Francisco's Industry Documents Library, in partnership with the Minnesota Attorney General's Office, has made public nearly 700 internal documents from a Midwest retailer as part of the state's lawsuit alleging the company ignored an internal warning before selling firearm

Warming waters draw summer 'feeding frenzies' by whales off Greenland and more — today's student signal.

Spain’s total solar eclipse delivered an unexpected sight: a corona glowing gold instead of its usual pearly white. Because the Sun was setting, its light passed through more atmosphere, while smoke from nearby wildfires filtered out even more blue light. The result was a dramati

The effects of global warming depend on species: The losers are legion, but a lucky few are winners. Now, researchers have shown that baleen whales are taking advantage of a newly opened-up fish bonanza in the Greenland Sea, east of Greenland and reaching to the Arctic Circle and

The brain has a remarkably flexible system for handling uncertainty and changing situations. Researchers found that the frontoparietal cortex constantly shifts how it communicates with other brain regions depending on what information is needed to make a decision. Rather than sim

When we read a news story about a new cancer treatment, an Alzheimer's breakthrough or an innovative technology, we rarely think about everything that happens behind the scenes before that information reaches newspapers, radio or television. Scientists publish their findings in s

Do your social media accounts feed you content that reflects your core beliefs and guiding principles? Our new research published in the Proceedings of the National Academy of Sciences shows that the algorithms supplying your feeds may be prioritizing content that clashes with yo

Europe's deadly, record-breaking summer heat waves sent temperatures above 40°C (104°F) in areas inhabited by 80 million people from mid-June to mid-August, according to official data analyzed by AFP, with many of those areas not used to such hot weather.

In the last few centuries, mammals and other animals have been going extinct at least 100 times faster than they did before humans arrived on the scene. So who will be next? Which species are most likely to survive, and which will die out?

Researchers have created an interactive map identifying 1.8 million individual trees in New York City, using a new approach that could optimize the placement of trees for cooling in cities around the world.

Are people from lower socioeconomic backgrounds more willing to help—or do the wealthy give more? For years, research has provided conflicting answers. A new study by Kühne Logistics University (KLU), based on data from approximately 680,000 people, resolves this contradiction: B

A molecular pathway known for controlling cell shape and movement also helps regulate the rhythm by which the vertebrate body is divided into repeated segments, FMI researchers report in the journal Development.

The use of antibiotics has traditionally been considered the gold standard in bacterial infection control—the more bacterial cells you kill, and the faster you kill them, the better. University of Tennessee, Knoxville Professor Dacheng Ren champions a different approach: engineer

The global push for solar energy expansion could carry hidden biodiversity costs, according to a study across China published in the journal Science on Thursday.

Learning to read and write cursive was once a rite of passage for practically every American schoolchild.

Extreme precipitation events are among the most damaging natural disasters and a major concern in our changing climate. In the U.S., since 1980, the most destructive events alone have caused more than 2,800 deaths and $700 billion in damages. But what is the total area of the cou
