| Posted: 13 Dec 2011 04:00 PM PST Researchers have developed a promising new inexpensive technique for fabricating large-scale flexible and stretchable backplanes using semiconductor-enriched carbon nanotube solutions. To demonstrate the utility of their carbon nanotube backplanes, the researchers constructed an artificial electronic skin device capable of detecting and responding to touch.  |
| Tycho's star shines in gamma rays, NASA's Fermi shows Posted: 13 Dec 2011 01:47 PM PST In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years. It's often called "Tycho's supernova" after the great Danish astronomer Tycho Brahe, who gained renown for his extensive study of the object. Now, years of data collected by NASA's Fermi Gamma-Ray Space Telescope reveal that the shattered star's remains shine in high-energy gamma rays.  |
| Posted: 13 Dec 2011 10:34 AM PST Researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That's fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle's bottom.  |
| Possible hints of Higgs boson remain in latest analyses, physicists say Posted: 13 Dec 2011 08:49 AM PST Two experiments at the Large Hadron Collider have nearly eliminated the space in which the Higgs boson could dwell, scientists announced in a seminar held at CERN Dec. 13. However, the ATLAS and CMS experiments see modest excesses in their data that could soon uncover the famous missing piece of the physics puzzle. Theorists have predicted that some subatomic particles gain mass by interacting with other particles called Higgs bosons. The Higgs boson is the only undiscovered part of the Standard Model of physics, which describes the basic building blocks of matter and their interactions.  |
| Whole new meaning for thinking on your feet: Brains of small spiders overflow into legs Posted: 12 Dec 2011 09:47 AM PST Researchers report that the brains of tiny spiders may fill their body cavities and overflow into their legs. As part of research to understand how miniaturization affects brain size and behavior, the scientists measured the central nervous systems of nine species of spiders, from rainforest giants to spiders smaller than the head of a pin. As the spiders get smaller, their brains get proportionally bigger, filling up more and more of their body cavities.  |
| Few allergies in unstressed babies, Swedish researchers find Posted: 12 Dec 2011 06:27 AM PST A new study shows that infants with low concentrations of the stress-related hormone cortisol in their saliva develop fewer allergies than other infants. Hopefully this new knowledge will be useful in future allergy prevention.  |
