| Genetic effects of Chernobyl radiation Posted: 22 Apr 2021 12:04 PM PDT Researchers utilized genomic tools to investigate potential health effects of exposure to ionizing radiation, a known carcinogen, as a result of the 1986 Chernobyl accident. One study found no evidence that genetic changes associated with radiation exposure are passed to children, while the second study documented the genetic changes in the tumors of people who developed thyroid cancer after being exposed as children or fetuses to the radiation released by the accident. Findings are being published close to the 35th anniversary of the Chernobyl disaster. |
| Mars has right ingredients for present-day microbial life beneath its surface, study finds Posted: 22 Apr 2021 12:04 PM PDT New research suggests that rocks in the Martian crust could produce the same kind of chemical energy that supports microbial life deep beneath Earth's surface. |
| Experimental drug shows potential against Alzheimer's disease Posted: 22 Apr 2021 12:04 PM PDT Researchers have designed an experimental drug that reversed key symptoms of Alzheimer's disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them. |
| Posted: 21 Apr 2021 01:00 PM PDT It's a common sight: pelicans gliding along the waves, right by the shore. These birds make this kind of surfing look effortless, but actually the physics involved that give them a big boost are not simple. Researchers have recently developed a theoretical model that describes how the ocean, the wind and the birds in flight interact. |
| Fearsome tyrannosaurs were social animals, study shows Posted: 20 Apr 2021 09:14 AM PDT The fearsome tyrannosaur dinosaurs may not have been solitary predators as popularly envisioned, but social carnivores with complex hunting strategies like wolves. |
| Analysis of famous fossil helps unlock when humans and apes diverged Posted: 20 Apr 2021 06:29 AM PDT Researchers examined the shoulder assembly of Little Foot, an Australopithecus that lived more than 3 million years ago, and may have confirmed how our human ancestors used their arms. |
