New clues in the hunt for the sources of cosmic neutrinos
New clues in the hunt for the sources of cosmic neutrinos 18 February 2016The sources of the high-energy cosmic neutrinos that are detected by the IceCube Neutrino Observatory buried in the Antarctic ice may be hidden from observations of high-energy gamma rays, new research reveals. These high-energy cosmic neutrinos, which are likely to come from beyond our Milky Way Galaxy, may originate in incredibly dense and powerful objects in space that prevent the escape of the high-energy gamma rays that accompany the production of neutrinos.
Impact of climate change on parasite infections depends on host immunity
Impact of climate change on parasite infections depends on host immunity 15 February 2016New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections. The study, led by Penn State University scientists, assessed the infection dynamics of two species of soil-transmitted parasites in a population of rabbits in Scotland every month for 23 years. The study's results could lead to new strategies for the treatment and prevention of infections from similar parasites in humans, livestock, and wildlife.
