Just like digital cameras, machines called cryo-electron microscopes (cryo-EMs) are getting better and better at taking pictures. Researchers report that they’ve created a cryo-EM image so sharp that it rivals images produced by x-ray crystallography, the gold standard for mapping the atomic contours of proteins. These new images will likely dramatically advance drugmakers’ attempts to make new medicines.
A geologist has discovered a plant that seems to grow only on top of kimberlite pipes—columns of volcanic rock that often contain diamonds. If the plant is as choosy as it seems to be, diamond hunters in West Africa will now have a simple, powerful way of finding diamond-rich deposits.
If you come from a country of immigrants, you’re more likely to crack a friendly smile on the street. That’s the conclusion of a new study, which may explain why Americans beam more than their Chinese and Russian counterparts.
You breathe it every minute, but there's hardly any molecular oxygen in space. Now, a new experiment has finally revealed why: because oxygen atoms cling tightly to stardust, preventing them from joining together to form oxygen molecules.
A neuroscientist who has been the target of animal rights activists says he is giving up on primate research. In a letter last week to fellow primate researchers, Nikos Logothetis cites a lack of support from colleagues and the wider scientific community as key factors in his decision.
