As cells create proteins, the proteins modulate synthesis speed by exerting a mechanical force on the molecular machine that makes them, according to a team of scientists who used a combination of computational and experimental techniques to understand this force.

Typhoid Mary may have infected a hundred or more people, but asymptomatic carriers of malaria infect far more people every year through mosquito vectors. An international team of researchers is working toward a way to identify malaria patients including infected individuals who show no malaria symptoms.
