the UK is addressing the issue of prion-infected blood and potential next steps. Antonio Giulivi, MD. Director, Blood Safety Surveillance, Health Canada; Faculty of Medicine, University of Ottawa: Update on Canadian Consensus Conferen...
Study in Royal Society journal on how relationship status influences sex ratios
... this paper the reasoning is reversed: it is shown how
to make secrets directly from first principles, and then how
to turn the process into a quantum entanglement generating one. This is very interesting, as entangl...
Stony Brook University medical researcher developing new medication to prevent colon cancer
...has made key contributions to our understanding of how
aspirin and aspirin-like drugs prevent colon and other cancers. He is now developing the highly promising nitroaspirin for the prevention of colon and pancreatic cancer, being supported by five NIH grants. He also pioneered the application of infrare...
Mice thrive despite massive genetic makeover
... "An important caveat, however, is that no matter how
detailed our analyses, our ability to test for a particular characteristic in mice is limited. All we know is that, in the time frame examined, there were no detectable changes in the specific features that we studied." The negligible impact...
Genetically modified parasite lets researchers probe immune system's memory
... vaccines. "We are so much better at understanding how
the immune system responds than we are at making a vaccine," Beverley notes. "These new results may help us better direct the immune response toward long-term vaccination."...
Mollusk research center will propagate endangered species
... the mussel is either alive or dead; we can't tell how
healthy it is," Neves said. "We are also studying whether the pink heelsplitter mussel is able to produce what would be the only natural purple pearls on the market." Experience for students is another priority. "It can be difficult to get typical fi...

the AHI1 gene works and how
its dysfunction leads to disordered brain development, it can tell us something about the biology un...
Genetic data crunching achieves milestone at Stanford
...ay data have also allowed scientists to understand how
various drugs affect the malaria bug, to find out what the immune system attacks in patients with autoimmune diseases and to pinpoint genes involved in multiple sclerosis. Sherlock estimates the database now supports 400 campus researchers doing work...
Early life stress can inhibit development of brain-cell communication zones, UCI study finds
...or the first time, the researchers have identified how
increased amounts of a key messenger for stress, the neuropeptide CRH, can inhibit the normal growth of dendrites, which are branch-like protrusions of neurons that send and receive messages from other brain cells. The researchers believe CRH ultima...
