NYU study reveals how brain's immune system fights viral encephalitis

...cking the virus' release, which could infect other cells in the brain. "There is no magic bullet in fighting viral infections in neurons," said NYU Biology Professor Carol Shoshkes Reiss, the study's senior author. "However, these findings show the redundancy of the immune system--when one response fails ...

Cricket's finicky mating behavior boosts biodiversity

...psule, to be transferred contains the actual sperm cells that impregnate the female. As a species begins to split into two separate species, says Mendelson, "the songs appear to be the first characteristic that changes." During the early part of the speciation process, says Mendelson, crickets of the two...
