Nearby planet-forming disk holds water for thousands of oceans

Posted: 20 Oct 2011 02:14 PM PDT

For the first time, astronomers have detected around a burgeoning solar system a sprawling cloud of water vapor that's cold enough to form comets, which could eventually deliver oceans to dry planets.

3-D simulations of nova explosions

Posted: 20 Oct 2011 09:22 AM PDT

A new study has shown how mixing of elements occurs during a nova explosion, thus solving an enigma that has puzzled stellar astrophysicists for over half a century.

Scientists discover way to determine when water was present on Mars and Earth

Posted: 20 Oct 2011 07:59 AM PDT

The discovery of the mineral jarosite in rocks analyzed by the Mars Rover, Opportunity, on the Martian surface had special meaning for a team of scientists who study the mineral here on Earth. Jarosite can only form in the presence of water.

Electrochemistry controlled with a plasma electrode

Posted: 20 Oct 2011 07:59 AM PDT

Engineers have made an electrochemical cell that uses a plasma for an electrode, instead of solid pieces of metal. The technology may open new pathways for battery and fuel cell design and manufacturing, making hydrogen fuel and synthesizing nanomaterials and polymers.

New generation of superlattice cameras add more 'color' to night vision

Posted: 20 Oct 2011 07:59 AM PDT

Recent breakthroughs have enabled scientists to build cameras that can see more than one optical waveband or "color" in the dark.

Viruses coaxed to form synthetics with microstructures akin to those of corneas, teeth and skin

Posted: 20 Oct 2011 07:59 AM PDT

Using a simple, single-step process, engineers and scientists have recently developed a technique to direct benign, filamentous viruses called M13 phages to serve as structural building blocks for materials with a wide range of properties.

Laser ion source will produce a new generation of semiconductors

Posted: 20 Oct 2011 05:48 AM PDT

For ion implantation, that is 'hammering' ions into the surface layer of the material, conventional ion accelerators are commonly used. Laser ion sources are much simpler, cheaper and more universal. However, they emit wide energy ions usually accompanied by some admixtures. Scientists have now produced a unique laser ion source has been built which is equipped with a special system for accelerating ions to a chosen energy and for eliminating admixtures.

SideBySide projection system enables projected interaction between mobile devices

Posted: 19 Oct 2011 11:50 PM PDT

Researchers have devised a system called SideBySide that enables animated images from two separate handheld projectors to interact with each other on the same surface. The system, suitable for games, education and a variety of other applications, is self-contained in special handheld devices. No external cameras or other sensors are required, which enables people to use the projectors to interact with each other anywhere and at anytime.

TapSense: Touchscreen technology distinguishes taps by parts of finger

Posted: 19 Oct 2011 11:48 PM PDT

Smartphone and tablet computer owners have become adept at using finger taps, flicks and drags to control their touchscreens. But researchers have found that this interaction can be enhanced by taking greater advantage of the finger's anatomy and dexterity. By attaching a microphone to a touchscreen, the scientists have shown they can tell the difference between the tap of a fingertip, the pad of the finger, a fingernail and a knuckle. This technology, called TapSense, enables richer touchscreen interactions.

One clock with two times: When quantum mechanics meets general relativity

Posted: 19 Oct 2011 11:47 PM PDT

General relativity, the joint theory of gravity, space and time gives predictions that become clearly evident on a cosmic scale of stars and galaxies. Quantum effects are fragile and observed on small scales like single particles and atoms. To test the interplay between them is very hard. Now theoretical physicists propose an experiment to overlap of the two theories.

The eyes have it: Computer-inspired creativity

Posted: 19 Oct 2011 11:47 PM PDT

Constraints on creativity imposed by computer-aided design tools are being overcome, thanks to a novel system that incorporates eye-tracking technology.

New benchtop polymer characterization method developed

Posted: 19 Oct 2011 11:44 PM PDT

Researchers have developed a new and highly efficient way to characterize the structure of polymers at the nanoscale -- effectively designing a routine analytical tool that could be used by industries that rely on polymer science to innovate new products, from drug delivery gels to renewable bio-materials.

Astronomers explain blue stragglers: How do mysterious stars stay so young?

Posted: 19 Oct 2011 11:44 PM PDT

Mysterious "blue stragglers" are old stars that appear younger than they should be: they burn hot and blue. Several theories have attempted to explain why they don't show their age, but, until now, scientists have lacked the crucial observations with which to test each hypothesis. Armed with such observational data, astronomers now report that a mechanism known as mass transfer explains the origins of the blue stragglers.

VISTA finds new globular star clusters and sees right through the heart of the Milky Way

Posted: 19 Oct 2011 11:41 PM PDT

Two newly discovered globular clusters have been added to the total of just 158 known globular clusters in our Milky Way. They were found in new images from ESO's VISTA survey telescope as part of the Via Lactea survey. This survey has also turned up the first star cluster that is far beyond the center of the Milky Way and whose light has had to travel right through the dust and gas in the heart of our galaxy to get to us.
