ScienceDaily (Nov. 16, 2009) — Despite minimal exposure to the regular geometric objects found in developed countries, African tribal people perceive shapes as well as westerners, according to a new study.
The scientists are currently working on the development of 'smart' contact lenses able to measure pressure within the eye and distribute medicament according to the measurements. They invented a new material called polydimethylsiloxane (PDMS). Then, they managed to place powdered silver, with antimicrobial properties, on the PDMS in a precise pattern, thus creating conductive wires. The scientists gave the PDMS-silver a contact-lens shape, so it could serve as a simple pressure sensor. A contact lens for continuous measurement of pressure within the eye and transmitting the data to a computer would greatly help doctors find out more about glaucoma, a major cause of blindness, and improve the ways of its treatment.
a few weeks ago we all got an email here at cosmic variance inviting us to the first ever “NASA tweetup” for the next Shuttle Launch. Sean and Mark are in Australia and JoAnne is in Egypt, and Julianne is a launch veteran… but Daniel and I decided that it was too good of an opportunity to pass up. This is despite the fact that neither of us actually knew what a tweetup was, or had ever tweeted before
Mercury's magnetic field is "alive." Volcanic vents ring the planet's giant Caloris Basin. And Mercury has shrunk in on itself more than previously suspected.
These are just a few of the new discoveries by NASA's MESSENGER spacecraft, which flew past Mercury on January 14, 2008. The results are described in a series of 11 papers published in a special July 4th issue of Science magazine.
