Broken mitochondria use ‘eat me’ proteins to summon their executioners

When mitochondria become damaged, they avoid causing further problems by signaling cellular proteins to degrade them. In a paper publishing April 11, 2019, in the journal Developmental Cell, scientists in Norway report that they have discovered how the cells trigger this... Continue Reading →

Eating small amounts of red and processed meats may increase risk of death

A new study out of Loma Linda University Health suggests that eating red and processed meats -- even in small amounts -- may increase the risk of death from all causes, especially cardiovascular disease. Saeed Mastour Alshahrani, lead author of... Continue Reading →

Protein-slaying drugs could be the next blockbuster therapies

When Craig Crews first managed to make proteins disappear on command with a bizarre new compound, the biochemist says that he considered it a “parlour trick”, a “cute chemical curiosity”. Today, that cute trick is driving billions of US dollars... Continue Reading →

Biologists Discover Unknown Powers in Mighty Mitochondria

Of all the organelles to be found inside eukaryotic cells, the DNA-sheltering nuclei might be the best-known, but the mitochondria are surely not far behind. Mitochondria are familiar as bean-shaped structures floating in the cytoplasm, and they are almost inevitably... Continue Reading →

Experiences of nature boost children’s learning

Spending time in nature boosts children's academic achievement and healthy development, concludes a new analysis examining hundreds of studies. Ming Kuo, associate professor in the Department of Natural Resources and Environmental Sciences at the University of Illinois and lead author on the Frontiers... Continue Reading →

High-speed, 3D microscope captures stunning videos of fruit fly nerve cells in action

Columbia engineers and neuroscientists have joined forces to create 3D videos of individual nerve cells moving, stretching and switching on inside fruit fly larvae as they move. Data gleaned from these videos reveals how nerve cells called proprioceptive neurons work... Continue Reading →

Is alcohol consumption more helpful than harmful? It depends on your age

Studies of health effects of alcohol consumption may underestimate the risks of imbibing, particularly for younger people, according to a new study in the Journal of Studies on Alcohol and Drugs. The research demonstrates that although cohort studies--the type of observational... Continue Reading →
