Researchers found that exposure to a slightly altered Ebola virus induced an immune response in monkeys that protected them from the parent virus.

Sour-taste proton channel found in mice

The otopetrin-1 proton channel is responsible for making mice sense sour tastes. “When something is acidic, it has a high concentration of protons, so it makes sense that a molecule like that could serve as a sensor for pH,” said Emily Liman, an author of the findings published in Current Biology.
