(Medical Xpress) -- A University of Michigan biologist and his colleagues have found that the strategies used by the tiny C. elegans roundworm to control its motions are remarkably similar to those used by the human brain to command movement of eyes, arms and legs. http://medicalxpress.com/news/2011-11-tiny-worms-human-like-neural-circuits.html Neuroscience Fri, 11 Nov 2011 13:24:20 EST news240240251 A team of researchers at EPFL, the University of Lausanne and the Salk Institute created super strong, marathon mice and nematodes by reducing the function of a natural inhibitor, suggesting treatments for age-related or genetically caused muscle degeneration are within reach. http://medicalxpress.com/news/2011-11-tweaking-gene-muscles-strong.html Genetics Thu, 10 Nov 2011 12:33:31 EST news240150802 Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms. http://medicalxpress.com/news/2011-11-live-action-worm-sperm-track-critical.html Genetics Tue, 01 Nov 2011 09:23:47 EST news239358216 Can the nerve signaling inhibitor tomosyn help retain long-term memory?

Based on research with their own worms, a team of neurobiologists at Brown University and several other institutions has now found that "Notch," a fundamental signaling pathway found in all animals, is directly involved in sleep in the nematode C. elegans. http://medicalxpress.com/news/2011-05-buenos-notch-es-universal-pathway.html Medical research Thu, 05 May 2011 12:54:26 EST news223818750
