Real-time tracking of mRNP complex assembly reveals various mechanisms that synergistically enhance translation repression
Using single-molecule fluorescence microscopy, Payr et al. reveal how multiple RNA-binding
proteins synergize to repress translation. One RNA-binding protein binds via facilitated
diffusion, recruits ...

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

Why next year's flu shot might not be as good as it should be
America's withdrawal from the World Health Organization is affecting the ability of U.S. scientists to track flu and other pathogens. That could be a blow to the development of the 2025 flu vaccine.
