Animals learn the hard way which sights, sounds, and smells are relevant to survival. New research in flies shows that the timing of these cues plays an important role in how mental associations arise, and elucidates brain pathways involved in this process.

How did humans get to be so much fatter than our closest primate relatives, despite sharing 99% of the same DNA? A new study suggests that part of the answer may have to do with an ancient molecular shift in how DNA is packaged inside fat cells, which curbed our body's ability to turn 'bad' white fat into 'good' brown fat.

Instead of the typical bell-shaped curve, the fossil record shows a fat-tailed distribution, with extreme, outlier, events occurring with higher-than-expected probability. Using the same mathematical tools that describe stock market crashes, scientists explain the evolutionary dynamics that give rise to universal patterns in the fossil record.

When the South African dung beetle rolls its dung ball through the savannah, it must know the way as precisely as possible. Scientists have now discovered that it does not orient itself solely on the position of the sun.

As Asia and Europe battle African swine fever outbreaks, new research shows how farmers' risk attitudes affect the spread of infectious animal diseases and offers a first-of-its kind model for testing disease control and prevention strategies. Getting just 10% of risk tolerant farmers to adopt biosecurity measures resulted in a significant reduction of disease, but keeping the disease under control required at least 40% of risk-takers to change their behaviors.

Scientists have created materials that shrink uniformly in all directions when heated under normal everyday conditions, using a cheap and industrially scalable process. This potentially opens up a new paradigm of thermal-expansion control that will make electronic devices more resilient to temperature changes.

People who order their Buffalo wings especially spicy and sometimes find them to be too 'hot,' should choose milk to reduce the burn, according to researchers, who also suggest it does not matter if it is whole or skim.

A shortage of high school physics teachers has led to teachers with little-to-no training taking over physics classrooms, reports show. This has led to additional stress and job dissatisfaction for those teachers -- and a difficult learning experience for their students. But new research indicates that focused physics professional development for teachers -- even those who have no prior physics training -- can lead to better experiences for both students and teachers, and can improve students' understanding of physics concepts.

By analyzing records in countries of the Amazon and Orinoco basins -- which include Brazil, Venezuela, Colombia, Bolivia, Peru and Ecuador -- researchers categorized 85 past and present initiatives or projects that work to preserve the South American River Turtle, or charapa (Podocnemis expansa), a critically endangered species. These projects are protecting more than 147,000 female turtles across the basin, an unprecedented figure.
