| New technology solves mystery of respiration in Tetrahymena Posted: 31 Mar 2022 12:14 PM PDT Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration -- using oxygen to generate cellular energy -- differently from other organisms such as plants, animals or yeasts. The discovery highlights the power of new techniques in structural biology and reveals gaps in our knowledge of a major branch of the tree of life. |
| Audio files are being used as 'digital drugs', survey suggests Posted: 30 Mar 2022 10:05 AM PDT A new study sheds light on the little-known phenomenon of binaural beats, where sounds purportedly evoke psychoactive effects. |
| Record broken: Hubble spots farthest star ever seen Posted: 30 Mar 2022 09:46 AM PDT NASA's Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the universe's birth in the big bang -- the farthest individual star ever seen to date. |
| Oxytocin treatment can take lions from ferocious to friendly Posted: 30 Mar 2022 08:13 AM PDT Lions typically aren't keen on making new friends. The giant cats guard their territory fiercely and can mortally wound a foe with a single swipe. While aggression is an advantage for apex predators in the wild, it poses real challenges for lions on reserves or in captivity, a number that is growing due to habitat loss. Researchers working on a wildlife reserve in Dinokeng, South Africa found that an intranasal application of the 'love hormone' oxytocin could make lion meet-cutes less life-threatening. |
| Unravelling the mystery of parrot longevity Posted: 29 Mar 2022 12:28 PM PDT Bigger brains have led some species of parrot to live surprisingly long lives, new research shows. |
| Zebra finch males sing in dialects and females pay attention Posted: 29 Mar 2022 12:28 PM PDT Male zebra finches learn their song by imitating conspecifics. To stand out in the crowd, each male develops its own unique song. Because of this individual-specific song, it was long assumed that dialects do not exist in zebra finches. However, with the help of an artificial intelligence technique, researchers have now been able to show that the songs of four different zebra finch populations differ systematically. They also discovered that these 'cryptic dialects' are decisive for the females' choice of mate. Thus, female zebra finches pay more attention to a cultural trait than to male appearance. |
| Researchers discover a mysterious, new type of wave in the Sun whose speed defies explanation Posted: 24 Mar 2022 09:26 AM PDT Researchers have discovered a new set of waves in the Sun that, unexpectedly, appear to travel much faster than predicted by theory. The high-frequency retrograde (HFR) waves -- which move in the opposite direction of the Sun's rotation -- appear as a pattern of vortices (swirling motions) on the surface of the Sun and move at three times the speed established by current theory. |
