Researchers get a first look at the mechanics of membrane proteins
CHAMPAIGN, lll. In two new studies, researchers provide the first detailed view of the elaborate chemical and mechanical interactions that allow the ribosome - the cell's protein-building machinery - to insert a growing protein into the cellular membrane. The first study, , gives an atom-by-atom snapshot of a pivotal stage in the insertion process: the moment just after the ribosome docks to a channel in the membrane and the newly forming protein winds its way into the membrane where it will reside.

Putting a fuel cell 'in your pocket'
Science | Technology Pete Wilton | 14 Apr 11 Technology using catalysts which make hydrogen from formic acid could eventually replace lithium batteries and power a host of mobile devices. Edman Tsang of Oxford University's Department of Chemistry and colleagues are developing new catalysts which can produce hydrogen at room temperature without the need for solvents or additives.

Search for dark matter moves one step closer to detecting elusive particle
Search for dark matter moves one step closer to detecting elusive particle
Dark matter, the mysterious substance that may account for nearly 25 percent of the universe, has so far evaded direct observation. But researchers from UCLA, Columbia University and other institutions participating in the international XENON collaboration say they are now closer than ever before. Their new results, announced today at the Gran Sasso National Laboratory in Italy, where the XENON experiment is housed deep beneath a mountain 70 miles west of Rome, represent the highest-sensitivity search for dark matter yet, with background noise 100 times lower than competing efforts.

Kepler Listens to an Orchestra of Solar-Type Stars
An international team of asteroseismologists, led by the University of Birmingham, has used data from the NASA Kepler Mission to sample the ‘stellar music' of 500 stars similar to the Sun, according to research published today (7 April 2011) . The team used the information from these natural resonances, which is coded in pulses of starlight, to measure the properties of the stars and will now be able to compare their findings with predictions based on models of the Milky Way galaxy.

Two Dying Stars Reborn as One
Cambridge, MA - White dwarfs are dead stars that pack a Sun's-worth of matter into an Earth-sized ball. Astronomers have just discovered an amazing pair of white dwarfs whirling around each other once every 39 minutes. This is the shortest-period pair of white dwarfs now known. Moreover, in a few million years they will collide and merge to create a single star.

Comet collisions could cause rippled planet rings, research shows
A curious corrugated pattern in Saturn's rings and similar features in Jupiter's main ring could be the residual effects of comet collisions, report astronomers at Cornell and the SETI Institute. The research, based on images taken by NASA's Cassini, Galileo and New Horizons spacecrafts, underscores the rings' valuable role in chronicling solar system history, the astronomers say.

Calculations with 14 Quantum Bits
Innsbruck physicists have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show results for the quantum mechanical phenomenon of entanglement.

NASA Announces 2011 Carl Sagan Fellows
NASA has selected five potential discoverers as the recipients of the 2011 Carl Sagan Postdoctoral Fellowships, named after the late astronomer. The Carl Sagan Fellowship takes a theme-based approach, in which fellows will focus on compelling scientific questions, such as "Are there Earth-like planets orbiting other stars?" Sagan once said, "Somewhere, something incredible is waiting to be known," which is in line with the Sagan Fellowship's primary goal: to discover and characterize planetary systems and Earth-like planets around other stars.

Seeing below the surface
In recent years, many airplane manufacturers have started building their planes from advanced composite materials, which consist of high-strength fibers, such as carbon or glass, embedded in a plastic or metal matrix. Such materials are stronger and more lightweight than aluminum, but they are also more difficult to inspect for damage, because their surfaces usually don't reveal underlying problems.
