Protein improves efficacy of tumor-killing enzyme

Scientists have devised a method for delivering tumor cell-killing enzymes in a way that protects the enzyme until it can do its work inside the cell. In their study in mBio®, researchers assembled microscopic protein packages that can deliver an enzyme called PEIII to the insides of cells. ... more

Symbiotic bacteria program daily rhythms in squid using light and chemicals

Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published in mBio®. The Hawaiian bobtail squid, Euprymna scolopes, houses a colony of Vibrio fischeri bacteria in its light organ, using the bacteria at ... more

Pain reliever shows anti-viral activity against flu

The over-the-counter anti-inflammatory drug naproxen may also exhibit antiviral activity against influenza A virus, according to a team of French scientists. New influenza vaccines must be developed annually, because the surface proteins they target mutate rapidly, the way cars used to get ... more
