Air bubbles could be the secret to artificial skin

June 11, 2013 2:01 pm | by Sarah Perrin, EPFL | News | Comments

Using foam substrates, researchers in Switzerland have made a flexible electronic circuit board. In experiments using various deformable materials, the team discovered a new kind of platform upon which to build circuits: elastomeric foams. These foams, used in packaging materials, serve as a substrate for metallic materials and can be stretched without disrupting electrical conductivity. The breakthrough could progress on electronic skin.

Study suggests second life for possible spintronic materials

June 6, 2013 11:01 am | News | Comments

Ten years ago, scientists were convinced that a combination of manganese and gallium nitride could be a key material to create spintronics, the next generation of electronic devices that operate on properties found at the nanoscale. But researchers grew discouraged when experiments indicated that the two materials were as harmonious as oil and water. A new study suggests that scientists should take another look at this materials duo.

Observation of spin Hall effect in quantum gas is step toward "atomtronics"

June 6, 2013 8:20 am | News | Comments

Researchers at NIST have reported the first observation of the spin Hall effect in a Bose-Einstein condensate, a cloud of ultracold atoms acting as a single quantum object. As one consequence, they made the atoms, which spin like a child's top, skew to one side or the other, by an amount dependent on the spin direction. The phenomenon is a step toward applications in "atomtronics".

Laser with "rainbow" buffer could allow subpicosecond pulses

June 4, 2013 8:46 am | News | Comments

Researchers in Munich, Germany, have recently published work that describes experiments in which inexpensive semiconductor lasers have produced high-energy light pulses as short as 60 picoseconds without the drawbacks of previous approaches in terms of power consumption and device size. They say the new technique, based on the use of a new Fourier domain mode-locked laser, could open the door to subpicosecond pulses.

Three veteran storm chasers killed by Oklahoma tornado

June 3, 2013 2:36 pm | by Kelly P. Kissel and Thomas Peipert, Associated Press | News | Comments

Tim Samaras, his son Paul, and colleague Carl Young died Friday night when an EF3 tornado with winds up to 165 mph turned on them near El Reno, Okla. Respected tornado researchers who used scientific equipment to help gather storm data, and shared their dramatic videos with television viewers and weather researchers, the three men died chasing a storm that killed 13 in Oklahoma City and its suburbs.

Chasing Tornadoes for Science

June 3, 2013 2:15 pm | Videos | Comments

In this video, Tim Samaras from the National Geographic Channel Storm Chasers talks about his passion for chasing and studying storm systems. He explains how he used National Instruments’ (NI) LabVIEW and CompactDAQ in a new instrument that is deployed on the ground in front of a tornado. After the storm he uses another NI application, DIAdem, to view the data that was collected.

Invention allows clear photos in dim light
