What's in a Femtosecond of Laser Light? A Map of Electron Energy

Illuminate a piece of metal, such as copper or silver, and the electrons get excited. These excitable particles in turn alter the electromagnetic fields that give rise to many of the properties technologists exploit, such as copper's excellent performance as a conductor of electricity.Efforts to observe electrons have become easier in recent years, thanks to advances with incredibly short laser pulses, despite the foundational principles of quantum mechanics that hold sway at this scale...

Missing Medical Data Could Harm Patients

Big clinical trials—to test new drugs or procedures—generate reams of important data about safety and efficacy. Only a fraction of that information sees the light of day, a publishing practice that could put patients at risk, according to a special report published this week in the British Medical Journal ( BMJ ).Even though scientific and medical journals are loaded with what might seem like endless reports—and lengthy methodology descriptions–from clinical trails each year, about half of clinical trial results go unpublished, An-Wen Chan, of the University of Toronto's Women's College Research Institute, noted in one of the seven new papers in the BMJ special section...
