New approach to form non-equilibrium structures

Although most natural and synthetic processes prefer to settle into equilibrium—a state of unchanging balance without potential or energy—it is within the realm of non-equilibrium conditions where new possibilities lie. Non-equilibrium systems experience constant changes in energy and phases, such as temperature fluctuations, freezing and melting, or movement. These conditions allow humans to regulate their body temperature, airplanes to fly, and the Earth to rumble with seismic activity.

Nike krypton laser achieves spot in Guinness World Records

A set of experiments conducted on the Nike krypton fluoride (KrF) laser at the U.S. Naval Research Laboratory (NRL) nearly five years ago has, at long last, earned the coveted Guinness World Records title for achieving "Highest Projectile Velocity" of greater than 1,000 kilometers per second (km/s), a speed equivalent to two-and-a-quarter million miles per hour.

Chemist develops X-ray vision for quality assurance

It is seldom sufficient to read the declaration of contents if you need to know precisely what substances a product contains. In fact, to do this you need to be a highly skilled chemist or to have genuine X-ray vision so that you can look directly into the molecular structure of the various substances. Christian Grundahl Frankær, a Postdoc at DTU Chemical Engineering, is almost both, as he has developed a method that allows him to use X-rays to look deep into biological samples.

The future of ultrashort laser pulses

Rapid advances in techniques for the creation of ultra-short laser pulses promise to boost our knowledge of electron motions to an unprecedented level.

Researchers demonstrate reconfigurable clusters made of colloidal particles as a form of data storage

A team of researchers with member affiliations to a large number of universities in the U.S. has created clusters of colloidal particles (spheres) in a liquid that is able to be manipulated in such a way as to represent different states such as "0" or "1" thereby suggesting a novel way to store large amounts of data in a small amount of liquid. In their paper published in the journal Soft Matter, the team describes their findings and suggests that soft matter may hold potential as a digital colloid for possible data storage in the future.

NASA Selects Contract for Mission Support Services at Ames

NASA has selected Wyle Laboratories, Inc., Houston, to support NASA's flight programs and mission projects, providing support for multiple sustained project management, research and technology development capabilities that encompass all phases of mission and project lifecycles at the agency's Ames Research Center in Moffett Field, California.

Satellite Study Reveals Parched U.S. West Using Up Underground Water

A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought.

Hubble Finds Three Surprisingly Dry Exoplanets

Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the sun -- and have come up nearly dry.

IHEP in China has ambitions for Higgs factory

Who will lay claim to having the world's largest particle smasher?. Could China become the collider capital of the world? Questions tease answers, following a news story in Nature on Tuesday. Proposals for two particle accelerators could accelerate China itself as a scientific leader, upstaging the Large Hadron Collider at CERN, Europe's famous particle-physics laboratory, where the LHC is the world's largest particle collider.

The physics of lead guitar playing

String bends, tapping, vibrato and whammy bars are all techniques that add to the distinctiveness of a lead guitarist's sound, whether it's Clapton, Hendrix, or BB King.
