A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional (1D) nanostructures. That could open the door for a broad range of uses…

<p>Understanding the biophysical cues provided by pathogenic particles may help vaccine developers fine tune the signals they already knew were being transmitted by the molecular information presented to the immune system. The research could provide a new tool for vaccine developers, said Krishnendu Roy, the Robert A. Milton Chair and professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. (Credit: Rob Felt, Georgia Tech)</p>

How big you are may be as important as what you look like, at least to immune system cells watching for dangerous bacteria and viruses.

The size of pathogenic particles and the density of the molecular…

Is a treatment only making things better or maybe also making some things a little worse?

That can be a nagging question in some medical decisions, where side effects are possible. But researchers at the…
