Roughly 40 percent of all medications act on cells' G protein-coupled receptors (GPCRs). One of these receptors, beta 2 adrenergic receptor site (B2AR), naturally transforms between two base configurations; knowing the precise location of ...

Researchers have used one of the brightest X-ray sources on the planet to map the 3-D structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than possible before. The new ...
Scientists have discovered how plants use steroid hormones to choose growth over defence when their survival depends on it. The findings published in the open-access scientific journal eLife could be used to engineer crops that combine ...
A team of researchers at the Max Planck Institute in Germany has found that a species of hornworm uses nicotine it gets from eating tobacco plants, as a means of defense. In their paper published in Proceedings of the National Academy of ...
