Blueprint for semi artificial photovoltaics

 R&D Daily November 21 2013 In leaves, two proteins are responsible for photosynthesis, and they perform the conversion of carbon dioxide into oxygen and biomass very efficiently. Scientists have now harnessed this capability by embedding these proteins into complex molecules developed in the laboratory. Their bio-based solar cell creates electron current instead of biomass.

Insulin without the needle

A new nanotechnology-based technique for regulating blood sugar in diabetics may give patients the ability to release insulin painlessly using a small ultrasound device, allowing them to go days between injections-rather than using needles to give themselves multiple insulin injections each day. The technique was developed by researchers at North Carolina State Univ. and the Univ. of North Carolina at Chapel Hill. R&D DAILY November 21
