Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command — simply by shining a light on them and varying its intensity. The cells are grown on a material called…

Researchers at University of California San Diego School of Medicine have developed a microbial detection technique so sensitive that it allows them to detect as few as 50 to 100 bacterial cells present on a surface. What’s more, they can test samples more efficiently — up to hundreds of samples in a single day. The…
