COLUMBUS, Ohio – Scientists have designed a screening tool that provides a fast, easy and relatively inexpensive way to predict levels of a specific toxin in lakes that are prone to blue-green algal blooms.

Blue-green algae is not your average pond scum – rather than consisting of plant-like organisms, blue-green algae actually are cyanobacteria, and some species are linked to the production and release of the toxin microcystin into the water. Human exposure to the toxin through drinking or recreational water contact can threaten public health by causing liver damage, neurological problems and gastrointestinal illness in humans. (more…)

Yale Researchers Identify Four Key Weapons in Immune System’s Arsenal

Yale University researchers have identified four unique host defense proteins among thousands that seem to play a crucial role in mobilizing the immune system’s response to bacterial infections, they report in the May 6 issue of the journal Science.

The findings suggest it may be possible to find new ways to assist immune-compromised patients to fight off a variety of pathogens, the authors say.

“We can start to think about how to mimic these chemical processes and deliver them in drug form,” said John D. MacMicking, associate professor of microbial pathogenesis at Yale School of Medicine and senior author the study. (more…)
