Using UV light to write on a DNA information-storage device

In an effort to make data storage more cost-effective, a group of researchers from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a DNA-based memory device that is "write-once-read-many-times" (WORM), and that uses ultraviolet (UV) light to make it possible to encode information.

SSRL helps Stanford scientists study enhanced organic semiconductor

Organic semiconductors could usher in an era of foldable smartphones, better high-definition television screens and clothing made of materials that can harvest energy from the sun needed to charge your iPad, but there is one serious drawback: organic semiconductors do not conduct electricity very well. Researchers at Stanford have changed that equation by improving the ability of the electrons to move through organic semiconductors.
