Counting the twists in a helical light beam

January 8, 2013 1:21 pm | by Caroline Perry, Harvard University | News | Comments

At a time when communication networks are scrambling for ways to transmit more data over limited bandwidth, a type of twisted light wave is gaining new attention. Called an optical vortex or vortex beam, this complex beam resembles a corkscrew, with waves that rotate as they travel. Now, applied physicists at the Harvard University have created a new device that enables a conventional optical detector—which would normally only measure the light's intensity—to pick up on that rotation.

Using sophisticated sensors and software, the researchers can precisely control the light, temperature, humidity, and carbon dioxide inside the cube.

Carbon found in Vesta's craters

January 8, 2013 8:43 am | News | Comments

Images taken by the framing camera onboard NASA's space probe Dawn show two enormous craters in the southern hemisphere of the asteroid Vesta, a remarkable protoplanet that is a time capsule of early planet formation in the solar system. Scientists have recently found that the asteroids that created these impact features also delivered dark, carbonaceous material to the protoplanet.

Better than diamond

January 7, 2013 1:39 pm | by Gunnar Bartsch | News | Comments

January 7, 2013 7:41 am | News | Comments

Armed with a better understanding of how glasses age and evolve, researchers at the University of Chicago and the University of Wisconsin-Madison raise the possibility of designing a new class of materials at the molecular level via a vapor-deposition process.

How computers push on the molecules they simulate

January 3, 2013 10:15 am | News | Comments

Computer simulations are essential to test theories and explore what's inaccessible to direct experiment. Digital computers can't use exact, continuous equations of motion and have to slice time into chunks, so persistent errors are introduced in the form of "shadow work" that distorts the result. Scientists have learned to separate the physically realistic aspects of the simulation from the artifacts of the computer method.

Record-setting p-type transistor demonstrated

January 3, 2013 7:35 am | by Larry Hardesty, MIT News Office | News | Comments

Researchers from Massachusetts Institute of Technology's Microsystems Technology Laboratories presented a p-type transistor with the highest "carrier mobility" yet measured. By that standard, the device is twice as fast as previous experimental p-type transistors and almost four times as fast as the best commercial p-type transistors.

December 21, 2012 12:21 pm | News | Comments

Just in time for the holidays, NASA's Cassini spacecraft, in orbit around Saturn for more than eight years now, has delivered another glorious, backlit view of the planet Saturn and its rings.On Oct. 17, 2012, during its 174th orbit around the gas giant, Cassini was deliberately positioned within Saturn's shadow, a perfect location from which to look in the direction of the sun and take a backlit view of the rings and the dark side of the planet.

Clays on Mars: More plentiful than expected

December 21, 2012 9:30 am | News | Comments

A new study indicates that clay minerals, rocks that usually form when water is present for long periods of time, cover a larger portion of Mars than previously thought.  In fact, the research team say clays were in some of the rocks studied by Opportunity when it landed at Eagle crater in 2004. But Opportunity doesn’t have the capability any longer to detect these clays, which were found using spectroscopic analysis from the Mars Reconnaissance Observer.

Scientists construct first map of how the brain organizes everything we see

December 20, 2012 11:40 am | by Yasmin Anwar, UC Berkeley | News | Comments

Our eyes may be our window to the world, but how do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see. They have created the first interactive map of how the brain organizes these groupings.

Cell phone data helps pinpoint source of traffic tie-ups

December 20, 2012 11:36 am | by Denise Brehm, Civil and Environmental Engineering | News | Comments

Researchers tracked traffic in Boston and San Francisco with cell tower and GPS data and analyzed bottlenecks. Their computer analysis suggested a possible strategy for relieving traffic tie-ups: Instead of asking all drivers to reduce their driving during commute hours, target those communities whose drivers contribute most to congestion.

Preventing heat buildup within 3D integrated circuits

December 19, 2012 1:39 pm | News | Comments

In the effort to pile more power atop silicon chips, engineers have developed the equivalent of miniature skyscrapers in 3D integrated circuits and encountered a new challenge: how to manage the heat created within the tiny devices. But a team of University of Texas at Arlington researchers is working first to minimize the heat generated and then to developing nanowindows that will allow the heat to dissipate before it damages the chip.
