In both cell cultures and mouse models, a drug used to treat Hepatitis C effectively protected and rescued neural cells infected by the Zika virus — and blocked transmission of the virus to mouse fetuses.

A type of virus that dominates water samples taken from the world’s oceans has long escaped analysis because it has characteristics that standard tests can’t detect. However, researchers at MIT and the Albert Einstein College of Medicine have now managed to isolate and study representatives of these elusive viruses, which provide a key missing link in virus evolution and play an important role in regulating bacterial populations, as a new study reports.

Once abundant in Southern California, the foothill yellow-legged frog inexplicably vanished from the region sometime between the late 1960s and early 1970s. The reasons behind its rapid extinction have been an ecological mystery.

The potential solution discovered by University of Saskatchewan researchers for producers stuck with unsellable fusarium-infected wheat may actually put cash in the farmers’ pockets and open up a new worm-based niche market in the feed industry.

“We want to help producers by making use of grain that is worth nothing and that no one knows how to dispose of safely,” said Fiona Buchanan, animal and poultry science professor.

MIT researchers have devised a miniaturized system that can deliver tiny quantities of medicine to brain regions as small as 1 cubic millimeter. This type of targeted dosing could make it possible to treat diseases that affect very specific brain circuits, without interfering with the normal function of the rest of the brain, the researchers say.
