Nov. 7th, 2008 02:38 pmAccording to Wired, Battlestar Galactica fans will be interested to learn that many of the props used on the show will be available for sale in January, including a full-sized Viper fighter and various costumes.
PhysOrg presents and interesting article on the challenges involved in generating a high-resolution 3D model of the Palazzo Medici in Italy.
University of Laval researchers have developed an adaptive mirror made from iron particles suspended in antifreeze (what is referred to a a ferrofluid) and coated with silver grains. The resulting mirror can be reshaped using a magnetic field, allowing it to quickly compensate for distortion in fields like astronomy and opthomology.
A recent study by the University of Nevada has concluded that, contrary to popular belief, static stretching of muscles before exercising may, in fact, weaken them, sometimes by as much as 30 percent. They recommend a brief, no more than 5 or 10 minute, aerobic warm-up to raise muscle temperature before stretching, something many modern coaches now advise, but suggest recommend dynamic, rather than static stretches to avoid the inhibitory response that causes muscle weakness.
Forensic investigators' work may just have gotten harder with a new breed of cleaners that use oxygen rather than chlorine. It seems that the oxygen will destroy hemoglobin. Chlorine has been used to remove bloodstains but the hemoglobin was still detectable after more than 10 washings.
Ottawa graffiti artists have taken to acid-etching their work into glass surfaces around the city, presenting a new and expensive headache for the city and store owners who must replace entire sheets of glass to remove the artwork.
