New biochip helps study living cells, may speed drug development
..."We conducted research with the chip while we were flying
in parabolas over the Gulf of Mexico, going from two times Earth's gravity to zero gravity again and again," he said. "There is absolutely no way this experiment could have been done without this chip." The current technology for analyzing cells' e...
