| Sounding rocket to peek at atmosphere of Venus Posted: 25 Nov 2013 02:21 PM PST A week after launching a new orbiter to investigate the upper atmosphere of Mars, NASA is sending a sounding rocket to probe the atmosphere of Venus.  |
| Nanotubes can solder themselves, markedly improving device performance Posted: 25 Nov 2013 01:48 PM PST Researchers have developed a way to heal gaps in wires too small for even the world's tiniest soldering iron. Junctions between nanotubes have high resistance, slowing down the current and creating hotspots. The researchers use these hot spots to trigger a local chemical reaction that deposits metal that nano-solders the junctions.  |
| Mach 1000 shock wave lights supernova remnant Posted: 25 Nov 2013 01:48 PM PST When a star explodes as a supernova, the material blasted outward from the explosion still glows hundreds or thousands of years later, forming a picturesque supernova remnant. What powers such long-lived brilliance? In the case of Tycho's supernova remnant, astronomers have discovered that a reverse shock wave racing inward at Mach 1000 (1,000 times the speed of sound) is heating the remnant and causing it to emit X-ray light.  |
| Flashes of brilliance: Roots of superfluorescent bursts from quantum wells discovered Posted: 25 Nov 2013 01:47 PM PST Spontaneous bursts of coherent light from solid-state materials shed new light on how particles interact and may lead to ultrahigh-speed optoelectronic devices for telecommunications.  |
| Search for habitable planets should be more conservative, experts say Posted: 25 Nov 2013 01:46 PM PST Scientists should take the conservative approach when searching for habitable zones where life-sustaining planets might exist, according to experts.  |
| Super SQUID: Measuring device for superconductors breaks world records Posted: 25 Nov 2013 09:18 AM PST The smallest, most sensitive measuring device for superconductors was just created.  |
| Step closer to composite-based electronics Posted: 25 Nov 2013 09:14 AM PST A new study demonstrates that electrical resistivity obeys a staircase-like dependence on the conducting particle concentration in composite materials.  |
| Pill-popping galaxy hooked on gas Posted: 25 Nov 2013 07:12 AM PST Our Galaxy may have been swallowing "pills" -- clouds of gas with a magnetic wrapper -- to keep making stars for the past eight billion years.  |
| Ultra-sensitive force sensing with levitating nanoparticle Posted: 25 Nov 2013 07:11 AM PST A recent study achieved the highest force sensitivity ever observed with a nano-mechanical resonator. The scientific results of this study have just been published.  |
| Steering electrons along chemical bonds Posted: 25 Nov 2013 07:11 AM PST Electron motions induced by a strong electric field are mapped in space and time with the help of femtosecond x-ray pulses. An x-ray movie of the crystal lithium hydride shows that the electric interaction between electrons has a decisive influence on the direction in which they move.  |
| EMRs provide method to discover new disease associations Posted: 24 Nov 2013 05:00 PM PST Researchers are repurposing genetic data and electronic medical records to perform the first large-scale phenome-wide association study.  |
| Water-based imaging maps brain neurons before surgery Posted: 21 Nov 2013 03:42 PM PST Some neurosurgeons are using a new approach to visualize the brain's delicate anatomy prior to surgery. The novel technique allows neurosurgeons to see the brain's nerve connections thus preserving and protecting critical functions such as vision, speech and memory. No needles, dyes or chemicals are needed to create the radiology scan. The main imaging ingredient? Water.  |
