A study published in today's online edition the American Journal of Human Genetics, allowed the first identification of a new form of adult onset muscular dystrophy. The research team led by Dr. Bernard Brais, neurogeneticist at the Research Centre of the Centre hospitalier de l'Université de Montréal (CRCHUM) and associate professor, Université de Montréal, in collaboration with European collaborators, demonstrated that recessive ANO5 mutations will lead to abnormal membrane repair of muscle fibers.

A microbe commonly found in the Chesapeake Bay and other waterways emits a poison not just to protect itself but to stun and immobilize the prey it plans to eat, a team of researchers from four universities has discovered. The findings about algae linked to massive fish kills could lead to new ways to slow the growth of these tiny but toxic marine creatures.

We normally think of pollinators as providing a valuable service to plants, and they certainly do. In exchange for nectar, pollinators like the well-known honey bee carry pollen from one plant to the other and thus promote cross-fertilization. But what happens when the pollinators aren't satisfied with their nectar rewards and decide to eat their generous plant partners? Just such a scenario arises in a number of plant-pollinator mutualisms in which the pollinator deposits eggs on the plant, which then develop into herbivorous larvae. What is a plant to do when faced with such a dilemma?

Biomedical scientists from the University of Central Florida and Louisiana State University have identified a way to block a "cell death signal" that they believe triggers brain damage during strokes.
