The twain finally meet: Nanowires and nanotubes combined to form intracellular bioelectronic probes
(Phys.org) —Miniaturized bioelectronic probes stand to transform biology and medicine by allowing measurement of intracellular components in vivo. Recently, scientists at Harvard University and Peking University designed, ...

New insights into the one-in-a-million lightning called 'ball lightning'
One of the rare scientific reports on the rarest form of lightning—ball lightning—describes better ways of producing this mysterious phenomenon under the modern laboratory conditions needed to explain it. The new study ...
