New device stores electricity on silicon chips

Posted: 22 Oct 2013 05:51 PM PDT

Solar cells that produce electricity 24/7. Cell phones with built-in power cells that recharge in seconds and work for weeks between charges: These are just two of the possibilities raised by a novel supercapacitor design invented by material scientists.

Baby's innate number sense predicts future math skill

Posted: 22 Oct 2013 02:08 PM PDT

A new study suggests that the strength of an infant's innate sense of numerical quantities can be predictive of that child's mathematical abilities three years later.

Researchers advance scheme to design seamless integrated circuits etched on graphene

Posted: 22 Oct 2013 02:08 PM PDT

Researchers have introduced an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene, a 2-D plane of carbon atoms.

Mutual fund managers invest similarly because of competitive pressures, might miss good investments

Posted: 22 Oct 2013 02:08 PM PDT

A researcher has found that institutional mutual fund investors tend to invest in companies that have an independent board of directors because it is perceived as a "safer" option, even though no evidence exists that demonstrates these companies perform better in the stock market.

4-D printing technology for composite materials developed

Posted: 22 Oct 2013 11:10 AM PDT

Researchers have successfully added a fourth dimension to their printing technology, opening up exciting possibilities for the creation and use of adaptive, composite materials in manufacturing, packaging and biomedical applications.

Shifting winds in turbine arrays

Posted: 22 Oct 2013 10:16 AM PDT

Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below.

Hydrogel implant enables light-based communication with cells inside body

Posted: 22 Oct 2013 08:36 AM PDT

As researchers develop novel therapies based on inducing specific cells to do specific things, getting the right message to the right group of cells at the right time remains a major challenge. Now researchers have developed a way to deliver a light signal to specific cells deep within the body.

Copper shock: An atomic-scale stress test

Posted: 22 Oct 2013 08:35 AM PDT

Scientists used a powerful X-ray laser to create movies detailing trillionths-of-a-second changes in the arrangement of copper atoms after an extreme shock. Movies like these will help researchers create new kinds of materials and test the strength of existing ones.

Low-priced plastic photovoltaics

Posted: 22 Oct 2013 08:34 AM PDT

Photovoltaic devices offer a green -- and potentially unlimited -- alternative to fossil fuel use. So why haven't solar technologies been more widely adopted? Quite simply, they're too expensive. Researchers have now come up with a technology that might help bring the prices down.

Long-sought pattern of ancient light detected

Posted: 22 Oct 2013 07:10 AM PDT

The journey of light from the very early universe to modern telescopes is long and winding. The ancient light traveled billions of years to reach us, and along the way, its path was distorted by the pull of matter, leading to a twisted light pattern. This twisted pattern of light, called B-modes, has at last been detected. The discovery, which will lead to better maps of matter across our universe, was made using the National Science Foundation's South Pole Telescope, with help from the Herschel space observatory.

Spatial, written language skills predict math competence

Posted: 22 Oct 2013 06:18 AM PDT

New longitudinal research from Finland has found that children's early spatial skills and knowledge of written letters, rather than oral language skills, predict competence in math. The study included over 1,800 children and has implications for the STEM fields and workforces.

Numerical validation of quantum magnetic ordering

Posted: 22 Oct 2013 06:17 AM PDT

Numerical simulations designed to confirm the magnetic characteristics of 3D quantum materials largely match the theoretical predictions. A new study set out to use numerical simulations to validate previous theoretical predictions describing materials exhibiting so-called antiferromagneting characteristics. A recently discovered theory shows that the ordering temperature depends on two factors-namely the spin-wave velocity and the staggered magnetization.

Lasers offer an automated way to test drinking water

Posted: 22 Oct 2013 06:16 AM PDT

To keep drinking water clean, experts are constantly monitoring our supply to check it for contaminants. Now laser technology will give them a helping hand: a new system automatically analyzes water samples at the waterworks itself.

Production of non-toxic flame retardants simplified

Posted: 22 Oct 2013 06:16 AM PDT

Electronics, vehicles, textiles – almost all modern-day products contain some form of plastic. Its high combustibility means it must be protected from naked flames. New techniques simplify the production of environmentally friendly flame retardants.

A chameleon in the physics lab

Posted: 21 Oct 2013 12:57 PM PDT

Active camouflage has taken a step forward with a new coating that intrinsically conceals its own temperature to thermal cameras.

Solar technology: Unique material far cheaper to produce and almost as efficient

Posted: 21 Oct 2013 06:45 AM PDT

In the near future, solar panels will not only be more efficient but also a lot cheaper and affordable for everyone, thanks to new research.
