Researchers Create Logic Circuits From DNA


Researchers at Duke University recently used DNA to craft tiny chips used in computers and electronic circuits. By mixing DNA snippets with other molecules and exposing them to light, researchers created self-assembling, DNA-based logic circuits. Once perfected the tech could serve as an endlessly abundant, cheap alternative to silicon semiconductors. Chris Dwyer, lead researcher on the project, says that one grad student using DNA to make self-assembling circuits could produce more logic circuits in one day than the global silicon chip industry can create in an entire month!"

Making More Solar Cells from Silicon


A new manufacturing process could cut the cost of making crystalline silicon wafers for solar cells by 80 percent. The process is being developed by Lexington, MA-based 1366 Technologies, which this week showed off the first solar cells made this way. The technology is key to the company's plan to make solar power cheaper than the electricity generated from coal within 10 years. Follow the links for more info.
