Oct. 8, 2024 There are nearly 4,000 native bee species in the United States, contributing to pollination in agricultural, urban and natural landscapes. Honey bees, however, are not native to the U.S., which has led to concerns that managed honey bee populations might negatively impact wild bees via competition for resources and sharing of pathogens. However, the team recently found that of the 33 genera of ...

Oct. 8, 2024 Scientists have revealed a new cellular adaptation to starvation, in which the mitochondria of yeast cells get coated by ribosomes. Surprisingly, the ribosomes attach to the mitochondrial outer membrane with a very unusual 'upside-down' orientation. The discovery of this mechanism has potential implications for our understanding of how stressed cancer cells survive ...

Oct. 8, 2024 Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality. In animal and human cells, chaperones of the Hsp70 class are at the heart of this control system, overseeing a wide array of biological processes. Yet, despite their crucial role, the ...

Sep. 25, 2024 Researchers have discovered inorganic nanostructures surrounding deep-ocean hydrothermal vents that are strikingly similar to molecules that make life as we know it possible. These nanostructures are self-organized and act as selective ion channels, which create energy that can be harnessed in the form of electricity. The findings impact not only our understanding of how life began, but can also ...
