See my most recent post on the AAAS Qualia Blog ( pdf or link ). I discuss a recent piece by Morgan Giddings published on the-scientist.com about her decision to leave academia and what she thinks is wrong with the current system.
The chytrid fungal disease chytridiomycosis is a major player in the worldwide amphibian decline. The disease, and the fungus that causes it (Batrachochytrium dendrobatidis), are more prevalent in some frog species and populations than others. Two recent studies reveal how some frogs gain resistance. Genetic Differences in Immunity Researchers from Cornell University looked at the genetic basis of natural variation in susceptibility to the fungus in lowland leopard frogs. Their findings were published last week in the Proceedings of the National Academy of Sciences (‘ MHC genotypes associate with resistance to a frog-killing fungus ‘). The authors focused on differences in the major histocompatibility complex (MHC), a key part of the immune system. MHC proteins only recognize certain pathogens. Their job. . . Read More
