A group of engineers working on a novel manufacturing technique at NASA`s Langley Research Center in Hampton, Va., have come up with a new twist on the popular old saying about dreaming and doing: "If you can slice it, we can build it."
That`s because layers mean everything to the environmentally-friendly construction process called Electron Beam [...]

One of the moons in our solar system that scientists think has the potential to harbor life may have a far more dynamic ocean than previously thought.
If the moon Europa is tilted on its axis even slightly as it orbits the giant planet Jupiter, then Jupiter`s gravitational pull could be creating powerful waves in Europa`s [...]

The Stowers Institute’s Linheng Li Lab has identified the precise location of the bone marrow stem cell niche. The findings were published today in the Advance Online Publication of Nature.
The Linheng Li Lab collaborated with several of the Institute’s support facilities to develop a new technology — ex vivo Imaging of Stem Cells, or EVISC [...]

A group of scientists at Korea Advanced Institute of Science and Technology (KAIST) has fabricated a working computer chip that is almost completely clear — the first of its kind. The new technology, called transparent resistive random access memory (TRRAM), is described in the journal Applied Physics Letters.
The new chip is similar in type to [...]

Chalmers researcher Andreas Dahlin has developed a biosensor with an artificial membrane, which means that membrane-bound proteins can retain their natural structure and function. The method facilitates the study of the function of the proteins, which could be of major significance in the search for new drugs.
One-third of all our proteins have the cell membrane [...]

A detailed analysis of the measurements of five different satellites has revealed the existence of the warm plasma cloak, a new region of the magnetosphere, which is the invisible shield of magnetic fields and electrically charged particles that surround and protect Earth from the onslaught of the solar wind.
The study was conducted by a team [...]

Astronomy & Astrophysics is publishing spectroscopic observations with NASA`s space-based Far-Ultraviolet Spectroscopic Explorer (FUSE) of the white dwarf KPD 0005+5106. The team of German and American astronomers who present these observations show that this white dwarf is among the hottest stars known so far, with a temperature of 200 000 K at its surface.
It is [...]

When the University of Chicago`s David Mazziotti talks about chemistry, perhaps he is thinking about how the behavior of all of the electrons in a molecule can be anticipated from the behavior of just two of its electrons.
For 50 years theoretical chemists have puzzled over the problem of predicting many-electron chemistry with only two electrons, [...]

A potent combination of powerful new analysis methods and abundant data from genomics projects is carrying microbiology forward into a new era. Bacteria in particular are shedding light on fundamental molecular and signalling processes of interest not just within microbiology, but across the whole spectrum of life sciences embracing higher organisms, including plants and vertebrates.
Medical [...]

People said it couldn`t be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage technology.
The researchers report in the Dec. [...]
