A combined FRET- and electrophysiology-based approach is used to study ATP/ADP ADP binding to the stimulatory nucleotide binding site of ATP-sensitive K+ channels and investigate their activation mechanism.

Charybdotoxin, a toxin produced by scorpions, blocks a K+ channel by binding in a lock-and-key fashion to the mouth of the channel and presenting a lysine amino group, which serves as a K+ mimic in the selectivity filter.
Live imaging and physical perturbations of spindles with unfocused poles reveal that mammalian spindle length emerges locally from kinetochore-fibers, but that global cues from focused spindle poles are needed to coordinate k-fibers across space and time and accurately segregate chromosomes.
William R Bishai, director of the KwaZulu-Natal Research Institute for Tuberculosis and HIV (K-RITH), argues that the best place to carry out research into a disease is in its midst.
