Inflatable antennae could give CubeSats greater reach: Design inflates with powder that turns into gas Posted: 06 Sep 2013 06:41 PM PDT Researchers have come up with a design that may significantly increase the communication range of small satellites, enabling them to travel much farther in the solar system.

Scientists use DNA to assemble a transistor from graphene Posted: 06 Sep 2013 11:19 AM PDT Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon -- if we could fashion it into ribbons 20 to 50 atoms wide. Could DNA help?

Touch goes digital: Electronic recording and replay of human touch demonstrated Posted: 06 Sep 2013 11:18 AM PDT Researchers report a breakthrough in technology that could pave the way for digital systems to record, store, edit and replay information in a dimension that goes beyond what we can see or hear: touch.

Debris flows on Arctic sand dunes are similar to dark dune spot-seepage flows on Mars Posted: 06 Sep 2013 08:42 AM PDT Scientists have demonstrated that frozen water in the form of snow or frost can melt to form debris flows on sunward-facing slopes of sand dunes in the Alaskan arctic at air temperatures significantly below the melting point of water. The debris flows consist of sand mixed with liquid water that cascade down steep slopes.

Indiana Jones meets George Jetson Posted: 06 Sep 2013 08:42 AM PDT A team of researchers has designed a microplasma source capable of exciting matter in a controlled, efficient way. This miniature device may find use in a wide range of applications in harsh environments, but can also help revolutionize archaeology.

Growing thin films of germanium Posted: 06 Sep 2013 08:42 AM PDT Researchers have developed a new technique to produce thin films of germanium crystals -- key components for next-generation electronic devices such as advanced large-scale integrated circuits and flexible electronics, which are required for gadgets that move or bend.

Shining a little light changes metal into semiconductor Posted: 06 Sep 2013 07:30 AM PDT Materials science engineers changed the electronic properties of new class of materials -- just by exposing it to light.

New opportunites found for waste heat Posted: 06 Sep 2013 07:30 AM PDT Physicists are working on an innovation that could boost vehicle mileage by 5 percent and power plant and industrial processing performance as much as 10 percent, by capturing waste heat and converting it to electrical power.

New connection between stacked solar cells can handle energy of 70,000 suns Posted: 06 Sep 2013 07:26 AM PDT Researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production. The new connections can allow these cells to operate at solar concentrations of 70,000 suns' worth of energy without losing much voltage as 'wasted energy' or heat.

Protection system for building works on sloping work surfaces, such as roofs Posted: 06 Sep 2013 07:13 AM PDT Researchers have developed an innovative protection system for building works, suitable for use on the edges of the surfaces with a slope greater than 10°, such as decks and roofs.

Iron in the sun: A greenhouse gas for X-ray radiation Posted: 06 Sep 2013 07:13 AM PDT Scientists have investigated for the first time X-ray absorption of highly charged iron ions. A transportable ion trap developed at MPIK was used for generation and storage of the ions. The high-precision measurements provide important new insight into the role of highly charged ions in astrophysical plasmas, e. g. for radiation transport inside stars.

Using digital cameras to measure the height of Northern Lights Posted: 06 Sep 2013 07:13 AM PDT Scientists came up with an idea for a new method to measure the height of aurora borealis after working on a 3-D movie for a planetarium.They used two digital single-lens reflex (SLR) cameras set 8 km apart to capture 3D images of Northern Lights and determine the altitude where electrons in the atmosphere emit the light that produces aurora.

Researching new detectors for chemical, biological threats Posted: 06 Sep 2013 07:10 AM PDT Scientists are building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.

Videos: Live streaming enjoyment for multi-screen applications Posted: 04 Sep 2013 06:33 AM PDT Whether you missed a TV show or a concert live recording of your favorite band: the Internet is a treasure trove of videos and all kinds of other multimedia content. Usually this content is streamed – that is, not saved on the computer, rather played directly over the browser in real time. But this method has a major drawback: if the available bit rate deteriorates, transmission quality suffers and the resulting video juddering and interruptions test the user's patience.

Making cars that are lightweight and crash-safe Posted: 04 Sep 2013 06:33 AM PDT The auto industry needs to have a rethink: having turned out ever heavier cars year on year, in future vehicles will have to be lighter with lower fuel consumption and CO2 emissions. If auto makers do not dramatically reduce the average CO2 emissions of their cars, they will face hefty fines. That was determined by the European Commission in a new piece of legislation.

Table lamps, smart phones: In with antennas, out with electrical cords Posted: 04 Sep 2013 06:33 AM PDT The pretty designer lamp on the table is meant to add charm to the room. If only the annoying cord wasn't there, then you could also put the lamp in the center of the table when it suited you. In future, you will be able to do just that thanks to SUPA Wireless technology. SUPA stands for Smart Universal Power Antenna, and the technology removes the need for electrical cords, whether for lamps, laptops or smartphones.
