New findings on how sharks achieve drag reduction could inspire the design of riblets for more efficient aircraft and boats. In their investigation of great white shark denticles, researchers found that ridge height and spacing play crucial roles in drag reduction at different swimming speeds. Higher middle ridges aid sharks in efficient cruising at slower speeds, while the lower side ridges become more critical for drag reduction during high-speed hunting... Read more ›

Scientists from across academic disciplines are extremely concerned about climate change. Many of them have already changed their own lifestyles or engaged in advocacy and protest, with even more being willing to do so in future. This is evident from a large-scale survey of scientists from all over the world. Read more ›

Checking whether an avocado is hard or soft by looking at it? This would require recognizing how the plant cells behave behind the skin. The same applies to all other cells on our planet: Despite more than 100 years of intensive research, many of their properties remain hidden inside the cell. Researchers now describe a new approach that can determine the particularly difficult-to-detect mechanical properties of the cell interior by... Read more ›

Cats are notoriously picky eaters. But what if we could design their foods around flavors that they're scientifically proven to enjoy? Researchers used a panel of feline taste-testers to identify favored flavor compounds in a series of chicken-liver-based sprays. The cats particularly enjoyed the sprays that contained more free amino acids, which gave their kibble more savory and fatty flavors. Read more ›

A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought. Read more ›
