Researchers have demonstrated for the first time that people can successfully navigate an obstacle course even after brain damage has left them with no awareness of the ability to see and no activity in the visual cortex, a region of the brain’s cortex that is primarily responsible for processing visual inputs. The findings published in [...]

Plugging in molecular wires
Photoinduced electron transfer occurs from photoexcited P700 in photosystem I (PSI) to a gold surface. A novel molecular connector system is used, in which an artificial molecular wire, which is assembled on the gold surface, was plugged into PSI by reconstitution. Analysis of the photoelectron transfer kinetics proved both the output of electrons from PSI [...]

Research done by scientists in Italy and Switzerland has shown that carbon nanotubes may be the ideal "smart" brain material. Their results, published December 21 in the advance online edition of the journal Nature Nanotechnology, are a promising step forward in the search to find ways to "bypass" faulty brain wiring. The research shows that [...]
Genes determining asymmetry probably arose in the first bilaterally symmetric organisms. Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body. The finding, reported online in advance of publication [...]
Physicists Cracked Hex Columns Mystery in Devil’s Postpile, Northern Ireland
posted in Earth, Headlines, SciencePhysicists at the University of Toronto have cracked the mystery behind the strange and uncannily well-ordered hexagonal columns found at such popular tourist sites as Northern Ireland’s Giant’s Causeway and California’s Devil’s Postpile, using water, corn starch, and a heat lamp. "The size of the columns, which varies from site to site between a few [...]
The final frontier got a bit closer today as Microsoft officially launched the public beta of its WorldWide Telescope, which is now available at WorldWideTelescope.Org . WorldWide Telescope is a rich Web application that brings together imagery from the best ground- and space-based observatories across the world to allow people to easily explore the night [...]
NJIT’s indefatigable math professor Bruce Bukiet is once again opining on outcomes for this season’s Major League Baseball teams. His picks are based on a mathematical model he developed in 2000. His goal is two-fold.“I use my mathematical model to determine whether it is worthwhile to wager on games during the baseball season,†he said. [...]
Electronics work better under cold conditions (-150o C or -240F): with less thermal noise, detectors are more sensitive and low-noise amplifiers reduce noise further. Furthermore, the speed and reliability are increased. Dutch-sponsored researcher Srinivas Vanapalli has investigated the possibilities for the extreme cooling of electronic components at a chip level. Besides research into extremely small [...]
Dutch researcher Alexander le Fèbre has demonstrated that a field-emission current signal can be used to arrange the position of thousands of nanometre-sharp needles. These probes can be applied to write and read in new storage media with an extremely high density, using bits on a nanometre scale. The development of the hard disk is [...]
