Movie mountain
Will disposable DVDs lead to an eco-disaster of Hollywood proportions? GREEN campaigners are up in arms at the idea of a new disposable technology: throwaway DVDs. While the discs may save you the trouble of returning rental movies to the video shop, the worry is that they could cause environmental... view more (2002-02-13)

40 Years of Research with Synchrotron Radiation at DESY
On Wednesday, May 19, starting at 1.30 p.m., the DESY research center will celebrate the anniversary of a very special kind of light: For 40 years, scientists have been conducting research with so-called synchrotron radiation at DESY - i.e. light with exceptional properties generated at... view more (2004-05-19)

Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or... view more (2007-02-16)

McGill researchers report breakthrough in rapid malaria detection
A research team led by Dr. Paul Wiseman of the Departments of Physics and Chemistry at McGill University has developed a radically new technique that uses lasers and non-linear optical effects to detect malaria infection in human blood, according to a study published in the Biophysical Journal.   view more (2007-12-20)
