| Researchers review data on reputed toxins thought to cause neurodegeneration Posted: 18 Jun 2021 10:40 AM PDT Biologists and neuroscientists have published an update on the reputed environmental toxins that have been suspected of being involved in mammal neurodegeneration. |
| Dragonflies: Species losses and gains in Germany Posted: 18 Jun 2021 10:40 AM PDT Over the past 35 years, there have been large shifts in the distributions of many dragonfly species in Germany. Those of standing water habitats have declined, probably due to loss of habitat. Running-water species and warm-adapted species have benefited from improved water quality and warmer temperatures. The study highlights the importance of citizen science and natural history societies for long-term data collection. |
| Phytoplankton: The discovery of a missing link Posted: 18 Jun 2021 10:40 AM PDT Biologists have identified a family of algae as a living missing link in the microscopic domain. |
| Climate warming can influence fungal communities on oak leaves across the growing season Posted: 18 Jun 2021 10:40 AM PDT Climate warming plays a larger role than plant genes in influencing the number and identity of fungal species on oak leaves, especially in autumn. This research by ecologists sheds light on how warming and tree genes affect the dynamics of fungal communities across the season. |
| New cause for intensification of oyster disease Posted: 18 Jun 2021 10:40 AM PDT Researchers reveal that intensification of major oyster disease was due to evolving parasite, not just drought as previously thought. |
| Start-stop system of hunting immune cells Posted: 18 Jun 2021 06:17 AM PDT Researchers decipher the basic biology of neutrophil swarming and now show that the cells also evolved an intrinsic molecular program to self-limit their swarming activity. The study elucidates how swarming neutrophils become insensitive to their own secreted signals that brought the swarm together in the first place. This process is crucial for the efficient elimination of bacteria in tissues. |
| How cells 'read' artificial ingredients tossed into genetic recipe Posted: 18 Jun 2021 06:17 AM PDT Researchers discovered that the enzyme RNA polymerase II recognizes and transcribes artificially added base pairs in genetic code, a new insight that could help advance the development of new vaccines and medicines. |
| Tug-of-war receptors for sour taste in fruit flies sheds light on human taste biology Posted: 18 Jun 2021 06:16 AM PDT Sour taste does not have the nearly universal appeal that sweet taste does. Slightly sour foods or drinks such as yogurt and lemon juice are yummy to many, but such highly sour foods as spoiled milk are yucky, even dangerous. Like humans, many other animals, including insects, prefer slightly acidic over very acidic foods. |
| Unraveling the origin of Alzheimer's disease Posted: 17 Jun 2021 11:36 AM PDT Researchers studying prions -- misfolded proteins that cause lethal incurable diseases -- have identified the surface features of human prions responsible for their replication in the brain. |
| Swim first, hunt later: Young Weddell seals need to practice navigating before hunting Posted: 17 Jun 2021 11:36 AM PDT Weddell seals, the southernmost born mammal, are known as champion divers. But they don't begin life that way. Researchers examined the development of diving behavior in Weddell seal pups and found that they time their dives with their mother but likely do not learn to forage at that time. Instead, they focus their early efforts on learning to swim and navigate under the sea ice. |
| Hired blade: Anchoring complex in plant cells recruits its own katana sword Posted: 17 Jun 2021 05:27 AM PDT Researchers have found that an anchoring complex in plant cells recruits its own version of the katana sword for cutting microtubules. The Msd1-Wdr8 complex is used to stabilize sites within plant cells where new microtubules are created, before it recruits katanin -- an enzyme named after the katana sword -- to cut and release new microtubules. |
| A biological blueprint for tough color Posted: 17 Jun 2021 05:27 AM PDT The unique mechanical and optical properties found in the exoskeleton of a humble Asian beetle has the potential to offer a fascinating new insight into how to develop new, effective bio-inspired technologies. |
