| U.S. coastline to see up to a foot of sea level rise by 2050 Posted: 17 Feb 2022 11:24 AM PST The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That's according to a NOAA-led report updating sea level rise decision-support information for the U.S. released in partnership with half a dozen other U.S.federal agencies. |
| Scientists reveal how Venus fly trap plants snap shut Posted: 17 Feb 2022 11:13 AM PST Scientists have revealed the three-dimensional structure of Flycatcher1, an aptly named protein channel that may enable Venus fly trap plants to snap shut in response to prey. The structure of Flycatcher1 helps shed light on longstanding questions about the remarkably sensitive touch response of Venus fly traps. The structure also gives the researchers a better understanding of how similar proteins in organisms including plants and bacteria, as well as proteins in the human body with similar functions (called mechanosensitive ion channels), might operate. |
| Flies possess more sophisticated cognitive abilities than previously known Posted: 17 Feb 2022 11:12 AM PST Common flies feature more advanced cognitive abilities than previously believed. Using a custom-built immersive virtual reality arena, neurogenetics and real-time brain activity imaging, researchers found attention, working memory and conscious awareness-like capabilities in fruit flies. |
| Posted: 16 Feb 2022 08:23 AM PST Researchers have identified a case of a sudden evolutionary change. In a new study, the scientists describe a population of columbines that have lost their petals, including the characteristic nectar spurs. The finding adds weight to the idea that adaptation can occur in large jumps, rather than merely plodding along over extended timespans. |
| Ancestors of legionella bacteria infected cells two billion years ago Posted: 15 Feb 2022 01:34 PM PST Researchers have discovered that the ancestors of legionella bacteria infected eukaryotic cells as early as two billion years ago. It happened soon after eukaryotes began to feed on bacteria. These results are also relevant to the chicken-or-egg debate about whether mitochondria or phagocytosis came first. |
