As bacterial infections impervious to drugs rise, so does the need to develop better antibiotics
Certain biological events, such as proteins changing their shapes to perform some functions, occur so quickly that current methods of molecular imaging cannot capture them. Now, a research team has created a machine-learning technique that can “fill in” missing data needed to document proteins in action in time scales of a few quadrillionths of a second.
An international team of scientists have observed a sunlight-fueled atomic “pump” working in the cells of a marine bacterium. The imaging was done with an advanced technique called time-resolved serial femtosecond crystallography.
