Filming ultrafast molecular motions in single crystal

Understanding the behavior of matter is crucial for advancing scientific fields like biology, chemistry, and materials science. X-ray crystallography has been instrumental in this pursuit, allowing scientists to determine ...

High speed protein movies to aid drug design

Researchers from the University of Southampton have developed technology to help scientists observe proteins in motion. Understanding how proteins move will allow novel drugs to be designed.

New discovery reveals how the egg controls sperm entry

After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo. This is according to a new study led by researchers ...

How archaea toggle the nitrogen-uptake switch to avoid overeating

By tightly regulating nitrogen uptake, microorganisms avoid overeating nitrogen and thus wasting energy. Scientists from the Max Planck Institute for Marine Microbiology now reveal how some methanogenic archaea manage to ...

Shape-shifting protein study could advance new drug development

Proteins do the heavy lifting of performing biochemical functions in our bodies by binding to metabolites or other proteins to complete tasks. To do this successfully, protein molecules often shape-shift to allow specific ...
