Oct. 28, 2024 Buildup of a protein called filamentous actin, or F-actin, in the brain inhibits the removal of cellular wastes, including DNA, lipids, proteins and organelles. The resulting accumulation of waste diminishes neuronal functions and contributes to cognitive decline. By tweaking a few very specific genes in the neurons of aging fruit flies, the ...

Oct. 25, 2024 For all its pervasiveness and the efforts to study it, cancer is still somewhat of a mystery. Why do some animals get it at a higher rate than others? This is the question at the heart of Peto's paradox, the observation that large animals, by virtue of their number of cells, are statistically more likely than smaller animals to develop and ...

Oct. 24, 2024 After only one to three days of a whiplash injury, scientists can predict which patients will develop chronic pain based on the extent of cross 'talk' between two regions of the brain, and the person's anxiety level after the injury, according to a new study . The study showed the more the hippocampus -- the brain's memory center -- talked to the cortex -- involved in long term memory storage -- ...

Oct. 24, 2024 A historical supernova documented by Chinese and Japanese astronomers in 1181 has been lost for centuries, until very recently. Yet, the newly found remnant shows some stunning characteristics that are puzzling astronomers. Now, it surrenders its secrets. A team provides the first detailed study of the supernova's structure and speed of expansion in ...

Oct. 29, 2024 What if a microbe could help curb the climate crisis? Meet UTEX-3222, aka 'Chonkus,' a cyanobacterium discovered living in the volcanic CO2 seeps off the coast of Vulcano, Sicily. Chonkus is like other photosynthetic cyanobacteria in that it consumes CO2 and incorporates it into its cells. However, what sets UTEX-3222 apart is its rapid, ...

Oct. 29, 2024 Weddell seals in Erebus Bay, Antarctica, may look like couch potatoes when they are resting on ice. However, these seals, which are the southernmost population of the southernmost living mammals, are exceptional divers that can reach depths of more than 900 meters and recorded dives lasting 96 minutes, which is well beyond their aerobic threshold. ...

Oct. 28, 2024 A new study shows the remarkable adaptability of the critically endangered Cat Ba langurs. Despite low genetic diversity, the langurs have retained key genetic traits that help them survive in their isolated environment on Cat Ba Island in Vietnam. One of these remarkable adaptations is the ability to drink salt ...
