Straight from the clinics. Braving the uncharted waters of posting raw biomedical manuscripts, the British Medical Journal(together with HighWire Press, Science's online publisher) has launched a preprint server for clinical research and medicine. Although the point is to rush findings to the scientific community, the site says submissions will be “screened to ensure that they contain original research” and maintain patient confidentiality.

Constant companions. From the velocity of light in a vacuum to the mass of an alpha particle, the so-called fundamental constants are essential to balancing the equations that describe the world around us. The National Institute of Standards and Technology has just released its first update of the constants since 1986, based on the latest experimental results and theoretical calculations. That means more decimals and less uncertainty.
