Tiny graphene drum could form future quantum memory

August 26, 2014 4:03 pm | Comments

Scientists in The Netherlands have demonstrated that they can detect extremely small changes in position and forces on very small drums of graphene. Graphene drums have great potential to be used as sensors in devices such as mobile phones. Using their unique mechanical properties, these drums could also act as memory chips in a quantum computer.

A glucose meter of a different color provides continuous monitoring

August 26, 2014 7:53 am | by Liz Ahlberg, Physical Sciences Editor, Univ. of Illinois, Urbana-Champaign | Comments

Univ. of Illinois engineers are bringing a touch of color to glucose monitoring. The researchers developed a new continuous glucose monitoring material that changes color as glucose levels fluctuate, and the wavelength shift is so precise that doctors and patients may be able to use it for automatic insulin dosing—something now possible using current point measurements like test strips.

Sorting cells with sound waves

August 26, 2014 7:36 am | by Anne Trafton, MIT News Office | Comments

Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Their device, about the size of a dime, could be used to detect the extremely rare tumor cells that circulate in cancer patients’ blood, helping doctors predict whether a tumor is going to spread.

Living organ grown from lab-created cells

August 25, 2014 2:25 pm | Comments

Laboratory-grown replacement organs have moved a step closer with the completion of a new study. Scientists have grown a fully functional organ from transplanted laboratory-created cells in a living animal for the first time. They have created a thymus, an organ next to the heart that produces immune cells known as T cells that are vital for guarding against disease.

Shaping the future of nanocrystals

August 22, 2014 8:55 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | Comments

The first direct observations of how facets form and develop on platinum nanocubes point the way towards more sophisticated and effective nanocrystal design and reveal that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.

Scientists develop water splitter that runs on ordinary AAA battery

August 22, 2014 7:27 am | by Mark Shwartz, Stanford Univ. | Comments

In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming. Now scientists at Stanford Univ. have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.

Researchers develop models to study polyelectrolytes

August 21, 2014 9:04 am | by Matt Shipman, News Services, North Carolina State Univ. | Comments

Researchers from North Carolina State Univ. have developed a novel and versatile modeling strategy to simulate polyelectrolyte systems. The model has applications for creating new materials as well as for studying polyelectrolytes, including DNA and RNA. Polyelectrolytes are chains of molecules that are positively or negatively charged when placed in water.

Water leads to chemical that gunks up biofuels production

August 21, 2014 7:53 am | by Mary Beckman, Pacific Northwest National Laboratory | Comments

Trying to understand the chemistry that turns plant material into the same energy-rich gasoline and diesel we put in our vehicles, researchers have discovered that water in the conversion process helps form an impurity which, in turn, slows down key chemical reactions. The study, which was reported online at the Journal of the American Chemical Society, can help improve processes that produce biofuels from plants.

Bacterial nanowires not what scientists thought they were

August 19, 2014 8:28 am | by Robert Perkins, Univ. of Southern California | Comments

For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric wires, using them to power themselves and transfer electricity to a variety of solid surfaces. A team led by scientists has now turned the study of these bacterial nanowires on its head, discovering that the key features in question are not pili as previously believed.

New tool makes a single picture worth a thousand—and more—images

August 14, 2014 5:57 pm | by Sarah Yang, Univ. of California, Berkeley | Comments

Software developed by Univ. of California, Berkeley computer scientists seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can give users the photographic gist of a kid on Santa’s lap, housecats, or brides and grooms at their weddings. It works by generating an image that literally averages the key features of the other photos.

Tattoo biobatteries produce power from sweat

August 13, 2014 12:45 pm | Comments

In the future, working up a sweat by exercising may not only be good for your health, but it could also power your small electronic devices. Researchers report that they have designed a sensor in the form of a temporary tattoo that can both monitor a person’s progress during exercise and produce power from their perspiration.

Foam favorable for oil extraction

August 13, 2014 7:49 am | by Mike Williams, Rice Univ. | Comments

A Rice Univ. laboratory has provided proof that foam may be the right stuff to maximize enhanced oil recovery (EOR). In tests, foam pumped into an experimental rig that mimicked the flow paths deep underground proved better at removing oil from formations with low permeability than common techniques involving water, gas, surfactants or combinations of the three.

Researchers show that how fast you drive might reveal exactly where you are going

August 12, 2014 7:41 am | Comments

Rutgers Univ. researchers have shown that GPS technology is not needed to show where a driver traveled. A starting point and the driver's speed are enough when using a technique dubbed “elastic pathing”, which predicts pathways by seeing how speed patterns match street layouts. This could cause concerns for privacy, however, since many insurance companies offer discounts in return for customers allowing their driving habits to be monitored.

Photo editing algorithm changes weather, seasons automatically

August 11, 2014 8:27 am | Comments

A computer algorithm being developed by Brown Univ. researchers lets users instantly change the weather, time of day, season or other features in outdoor photos with simple text commands. Machine learning and a clever database make it possible. A paper describing the work will be presented at SIGGRAPH 2014.

Multiple UAVs perform autonomous formation flight

August 8, 2014 8:05 am | by John Toon, Georgia Institute of Technology | Comments

These days, unmanned aerial vehicles (UAV) typically fly alone with a team of ground operators controlling their activities through teleoperation or waypoint-based routing.  But one aircraft can only carry so many sensors, limiting its capabilities. That’s one reason why a fleet of autonomous aircraft can be better than one flying alone.
