New way to bump off ticks: Dry up their saliva

Saliva from a tick's bite can transmit pathogens that cause serious illnesses, such as Lyme disease, and significant agricultural losses. Current insecticides have drawbacks, so scientists have been seeking new ways to prevent ...

Study reveals how nanochannels select potassium ions

(Phys.org)—One of the mysteries in biology is how cells can selectively diffuse potassium across a membrane. Biological systems rely on a delicate balance between these potassium and sodium ion concentrations in the surrounding ...

Sixth sense: How do we sense electric fields?

A variety of animals are able to sense and react to electric fields, and living human cells will move along an electric field, for example in wound healing. Now a team lead by Min Zhao at the UC Davis Institute for Regenerative ...

Study find electricity in biological clock

Biologists from New York University have uncovered new ways our biological clock's neurons use electrical activity to help keep behavioral rhythms in order. The findings, which appear in the journal Current Biology, also ...
