| Bat brains organized for echolocation and flight Posted: 25 May 2022 12:17 PM PDT A new study shows how the brains of Egyptian fruit bats are highly specialized for echolocation and flight, with motor areas of the cerebral cortex that are dedicated to sonar production and wing control. |
| Artificial cilia could someday power diagnostic devices Posted: 25 May 2022 10:12 AM PDT Researchers have now designed a micro-sized artificial cilial system using platinum-based components that can control the movement of fluids at such a scale. The technology could someday enable low-cost, portable diagnostic devices for testing blood samples, manipulating cells or assisting in microfabrication processes. |
| Hot-blooded T. rex and cold-blooded Stegosaurus: Chemical clues reveal dinosaur metabolisms Posted: 25 May 2022 08:08 AM PDT There's a new method for determining whether dinosaurs were hot- or cold-blooded, using clues in their bones that indicated how much the individual animals breathed in their last hour of life. The study shows that the bird-hipped dinosaurs like T. rex and Brachiosaurus were hot-blooded, while the lizard-hipped dinosaurs like Triceratops and Stegosaurus were cold-blooded. |
| Genetic roots of 3 mitochondrial diseases ID'd via new approach Posted: 25 May 2022 08:08 AM PDT Researchers have identified the genetic causes of three mitochondrial diseases by figuring out what dozens of poorly understood mitochondrial proteins do. The functions of hundreds more mitochondrial proteins remain unknown, indicating that this approach could be a promising path to finding better ways to diagnose and treat the bewildering array of conditions linked to malfunctioning mitochondria. |
| Mice choose best escape route without ever experiencing threat Posted: 25 May 2022 08:08 AM PDT Escaping imminent danger is essential for survival. Animals must learn a new environment fast enough for them to be able to choose the shortest route to safety. But how do they do this without ever having experienced threat in the new environment? |
| Posted: 25 May 2022 07:29 AM PDT Researchers have outlined a powerful new tool for monitoring trade of rare and endangered fish species in Hong Kong wet markets. Using environmental DNA (eDNA) present in the drain runoff water of fish markets, researchers were able to extract and sequence enough DNA to identify over 100 species of fish that had passed through the market. |
| First Australians ate giant eggs of huge flightless birds, ancient proteins confirm Posted: 25 May 2022 07:29 AM PDT Scientists settle debate surrounding species that laid eggs exploited by early Australian people around 50,000 years ago. Shell proteins point to Genyornis, which was among the 'mega-fauna' to go extinct a few thousand years after humans arrived on the continent. |
| Secrets of tree hyraxes in Kenya uncovered with new research techniques Posted: 25 May 2022 07:29 AM PDT In addition to audio recordings and laser scanning, a thermal imaging camera has been adopted for use in research focused on threatened mammals that hide from poachers in Kenya's Taita Hills. |
| When male buddies become less important than female mating partners Posted: 25 May 2022 07:29 AM PDT Close friendships among males are rare in the animal kingdom, as males usually compete for rank and access to females. However, male friendships can also be beneficial for male reproduction, as friends can provide support in climbing the rank ladder or defending females from other males. Scientists have now investigated the benefits of male friendships in wild Guinea baboons in Senegal. |
| Researchers develop new biobattery for hydrogen storage Posted: 25 May 2022 07:29 AM PDT A team of microbiologists has succeeded in using bacteria for the controlled storage and release of hydrogen. This is an important step in the search for carbon-neutral energy sources in the interest of climate protection. |
| Some nomadic birds look for social cues to stop migrating Posted: 25 May 2022 05:05 AM PDT A study of nomadic pine siskins, a type of finch often seen on backyard feeders, found that when male migratory siskins were paired with a settled male bird in captivity, they started exhibiting signs of ending migration too. They stopped restless flying and lost body mass, fat stores and muscle size, compared to a control group placed in solo enclosures. The apparent reliance on social cues for the end of migration has implications for other nomadic animals as well. |
| Horses and pigs sense harsh speaking tones Posted: 24 May 2022 07:05 AM PDT How we speak matters to animals. Horses, pigs and wild horses can distinguish between negative and positive sounds from their fellow species and near relatives, as well as from human speech. The study provides insight into the history of emotional development and opens up interesting perspectives with regards to animal welfare. |
