ANN ARBOR, Mich.---At the scale of the very small, physics can get peculiar. A University of Michigan biomedical engineering professor has discovered a new instance of such a nanoscale phenomenon---one that could lead to faster, less expensive portable diagnostic devices and push back frontiers in building micro-mechanical and "lab on a chip" devices.

Montreal, May 17, 2010 – The world's biggest investigation on possible links between cell phone use and brain tumours is inconclusive, according to a Canadian scientist who collaborated on the Interphone International Study Group. Jack Siemiatycki, a professor at the University of Montreal and an epidemiologist at the University of Montreal Hospital Research Center, says restricted access to participants compromised the validity of results of the study to be published in the May 18 International Journal of Epidemiology.

Professor Alexander Balandin and a team of UC Riverside researchers, including Chun Ning Lau, an associate professor of physics, have taken another step toward new technology that could keep laptops and other electronic devices from overheating.

BOULDER, Colo. – Physicists at JILA have demonstrated a new tool for controlling ultracold gases and ultracold chemistry: electric fields.
