Xavier Nogués (IMIM) talks about his research on osteoporosis while Jean Michel Claverie, from the CNRS, tells us about his discovery of mimiviruses. Other news include articles on why a bit of stress can be protective for your cells; the existence of spleen neutrophils; how the fate of embryonic stem cells is controlled; new targets against Duchenne dystrophy; and the discovery of new anti-angiogenic compounds.
