Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.
Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More
Viruses are the most abundant biological entities on the planet with approximately 1030 in the world’s oceans at any time. As such, they play a central role in global nutrient cycling. Despite their ecological importance, little is known about how viruses interact with their hosts due to the dif... Read More
