Why is The Scientist giving prominence to a live bovine spongiform encephalopathy (BSE) test for which no data is available?1 The question is particularly important in view of the fact that the July issue of Clinical and Diagnostic Laboratory Immunology carries published research of a live BSE test,2 which has already been patented along with a patent for the human equivalent of Creutzfeldt-Jakob disease.
Jamming the epidermal growth factor (EGF) receptor allows severed neurons to regenerate.1 "It's a surprising finding," says Martin Schwab of the University of Zurich, as activation of the EGF receptor is normally associated with proliferation and growth of cells.Previous research that sought to explain why mammalian axons fail to regenerate in the wounded brain or spinal cord found several inhibitory cues that prevent healing. The culprits include proteins associated with myelin and proteoglycan
NASA scientists, in conjunction with Guava Technologies of Hayward, Calif., recently announced a compact prototype flow cytometer that functions in zero-gravity, for use aboard the International Space Station.
