On a larger scale, this research may help fight against pollinator declines through better design of rangeland restoration projects.      Scientists at the USDA Forest Service’s ...

The brain is not only the most complex organ of the human body, but also one of the most difficult to study. To understand the roles of different regions of the human brain and how they interact, it is crucial to measure neuronal activity with awake subjects while they perform controlled tasks. However, the most accurate measurement devices are invasive, which greatly limits their use on healthy humans in real-life settings. To overcome this major obstacle, scientists have come up with ingenious techniques to measure brain activity in safe and ...

ITHACA, N.Y. – Whirligig beetles, the world’s fastest-swimming insect, achieve surprising speeds by employing a strategy shared by speedy marine mammals and waterfowl, according to a new Cornell University study that rewrites previous explanations of the physics involved. The centimeter-long beetles can reach a peak acceleration of 100 meters per second and a top velocity of 100 body lengths per second (or one meter per second). Not only do the results explain the whirligig’s Olympian speeds, but they also offer valuable insights for bio-inspired designers of near-surface water robots and uncrewed boats. Until ...

Sleep is a fundamental need, just like food or water. “You’ll die without it,” said Keith Hengen, an assistant professor of biology at Washington University in St. Louis. But what does sleep actually accomplish? For years, the best researchers could say is that sleep reduces sleepiness — hardly a satisfying explanation for a basic requirement of life. But by melding concepts from the fields of physics and biology, Hengen and a team of Arts & Sciences researchers have constructed a theory that could explain both the meaning of sleep and the complexity of the brain. As reported in a new study published ...

COLUMBUS, Ohio – New research shows that the recently emerged BA.2.86 omicron subvariant of the virus that causes COVID-19 can be neutralized by bivalent mRNA vaccine-induced antibodies in the blood, which explains why this variant did not cause a widespread surge as previously feared. However, the study in cell cultures showed this SARS-CoV-2 variant can infect human cells that line the lower lung and engage in virus-host cell membrane fusion more efficiently, two features linked to severe disease symptoms. The study is published today (Jan. 8, 2024) in the journal Cell. The BA.2.86 variant of omicron is the ancestor of the currently dominating JN.1 and has about ...
