Scientists find nanowires capable of detecting individual viruses
...r indication of the virus's presence. Simultaneous electrical
and optical measurements using fluorescently labeled influenza A confirmed that these conductance changes corresponded to binding and unbinding of single viruses from nanowire devices. In addition to influenza A, the Lieber group tested nanowire arra...

Mouse study shows NPAS3 and NPAS1 genes may be linked to psychosis
...er than the typical excitatory neurons, which pass electrical
signals amongst themselves and act as the brain's wiring. The role of inhibitory interneurons, on the other hand, is to dampen the activity of excitatory neurons. The NPAS1 and NPAS3 proteins are transcription factors that can activate or deactiv...
APS awards more than $140,000 to minority students of physiology
