Scientists have developed nanobodies that can be labelled on certain amino acids. This provides a direct route for solving new X-ray crystal structures of protein complexes important for gaining mechanistic understanding of cellular processes, which is important in the development of drugs.
Picture two schools of fish swimming in clockwise and counterclockwise circles. It's enough to make your head spin, and now scientists have discovered the 'chiral spin mode' - a sea of electrons spinning in opposing circles.
Using atoms cooled to just billionths of a degree above absolute zero, a team of researchers has discovered an intriguing magnetic behavior that could help explain how high-temperature superconductivity works.
