Breakthrough Polymer Is Lightweight, Conductive, Corrosion-Proof, Flex
University of Virginia engineering professor Mool C. Gupta and his team have used carbon nanotubes to unite the virtues of plastics and metals in a new ultra-lightweight, conductive material that may revolutionize electromagnetic shielding and more. Sensitive electronic devices like cell phones and computers require shielding from electromagnetic interference (EMI). Such shielding -- which must be electrically conductive -- has traditionally been made of metal, which poses a weight problem in the push to miniaturize and lighten electronics. In response, Gupta led a team that has developed an ultra-lightweight nanocomposite that outperforms conventional shielding. Genetic Key To Growth Of New Arteries Is Identified
Researchers at the San Francisco VA Medical Center have uncovered part of the genetic mechanism that causes new arteries to grow in response to blocked arteries. HIV-TB Spreads In Africa, Undermines Control Of World's Two Deadliest
The largely unnoticed collision of the global epidemics of HIV and tuberculosis has exploded to create a deadly co-epidemic that is rapidly spreading in sub-Saharan Africa. However, health systems cannot adequately diagnose, treat, or contain the co-epidemic due to unanswered scientific and medical questions, according to a new report. The report urges research and immediate action to thwart co-epidemic as threat of multi-drug resistant tuberculosis/HIV mounts. Researchers Uncover Critical Player In Cell Communication
Johns Hopkins researchers have teased out the function of a protein implicated in Williams-Beuren syndrome, a rare cognitive disorder associated with overly social behavior and lack of spatial awareness. Called TFII-I, or TF "two eye,"the protein long known to help control a cell's genes also controls how much calcium a cell takes in, a function critical for all cells, including nerves in the brain. The study will be published this week in Science. NIST Helps Beam Time To TV Viewers In The Middle East
Millions of satellite television and radio users in North Africa and the Middle East can now see and hear the precise time of day, thanks to technical assistance and a custom-built time signal generator from NIST. A Good Game Of Golf -- Mind Over Matter
Ever stood on the tee and as you feel the eyes on the other golfers on you, your heart starts to race, your palms become sweaty, and you worry about making a mess of the shot? If this has happened, you are experiencing performance stress. A new study from the University of Alberta shows the strategies that elite golfers use to manage performance stress effectively. Neutron Scatter Camera Detects Shielded Radiation To Find Smuggled Nuc
In an effort to find an answer to the problem of identifying smuggled special nuclear material, researchers say a neutron scatter camera they are developing may be able to detect radiation from much greater distances and through more shielding than current detection instruments. 'Good Vibrations' From Deep-sea Smokers May Keep Fish Out Of Hot Water
The long-held assumption that black smokers are silent is wrong, according to recently published research led by Timothy Crone, a University of Washington doctoral student in oceanography. It's prompting scientists to wonder: Could the sound and vibrations of black smokers be the reason fish in total darkness avoid being poached by waters as hot as 750 F? And might similar sounds guide them to the smorgasbord of tube worms, mussels, shrimp, snails and other fauna at vents with more temperate waters? It's Alive (ish)
Scientists are growing rat neurons in a dish to learn about human brain development. They're only clumps of brain, but they're learning. By Brandon Keim. Bollywood Film Hits All Marks
A Hindi film critic says Dhoom 2 is too Hollywood -- glossy, superficial and lacking Indian cinematic soulfulness. And lawyers are going after the stars for an obscene kiss. This flick is bound to make a mint. In Beyond the Beyond.
