Programming smart molecules: Machine-learning algorithms could make chemical reactions intelligent

Posted: 12 Dec 2013 01:03 PM PST

Computer scientists have shown that an important class of artificial intelligence (AI) algorithms could be implemented using chemical reactions. In the long term, they say, such theoretical developments could open the door for "smart drugs" that can automatically detect, diagnose, and treat a variety of diseases using a cocktail of chemicals that can perform AI-type reasoning.

Keeping the lights on: New way to predict cascading power outages

Posted: 12 Dec 2013 01:03 PM PST

A method of assessing the stability of large-scale power grids in real time could bring the world closer to its goal of producing and utilizing a smart grid. The algorithmic approach can predict future massive instabilities in the power grid and make power outages a thing of the past.

Noble gas molecule discovered in space

Posted: 12 Dec 2013 11:21 AM PST

A molecule containing a noble gas has been discovered in space. The molecule, argon hydride, was seen in the Crab Nebula, the remains of a star that exploded 1,000 years ago.

Revolutionizing solar energy: Quantum waves found at the heart of organic solar cells

Posted: 12 Dec 2013 11:20 AM PST

Researchers have been able to tune 'coherence' in organic nanostructures due to the surprise discovery of wavelike electrons in organic materials, revealing the key to generating "long-lived charges" in organic solar cells - material that could revolutionize solar energy.

Graphene-based nano-antennas may enable networks of tiny machines

Posted: 12 Dec 2013 10:25 AM PST

By taking advantage of the unique electronic properties of the material known as graphene, researchers now believe they're on track to connect networks of nanomachines powered by small amounts of scavenged energy.

Smashing science: Scientists discover how explosives respond to shockwaves

Posted: 12 Dec 2013 10:25 AM PST

Researchers have combined ultrafast time-resolved experimental measurements with theory to reveal how an explosive responds to a high-impact shock.

Physicists provide answers for predicted behavior in relaxors: Thin films studied used in electronic devices

Posted: 12 Dec 2013 10:23 AM PST

New research shows that behavior can be predicted and understood in thin films made of materials called relaxors, which can be used in electronic devices.

Fast radio bursts might come from nearby stars

Posted: 12 Dec 2013 09:34 AM PST

First discovered in 2007, "fast radio bursts" continue to defy explanation. These cosmic chirps last for only a thousandth of a second. The characteristics of the radio pulses suggested that they came from galaxies billions of light-years away. However, new work points to a much closer origin -- flaring stars within our own galaxy.

Light and sound fire scientists' imaginations

Posted: 12 Dec 2013 09:33 AM PST

The state of the art in photonics, phononics and phoXonics is discussed in a new open-access review.

Hubble Space Telescope sees evidence of water vapor venting off Jupiter moon

Posted: 12 Dec 2013 08:33 AM PST

NASA's Hubble Space Telescope has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface. Previous scientific findings from other sources already point to the existence of an ocean located under Europa's icy crust. Researchers are not yet fully certain whether the detected water vapor is generated by erupting water plumes on the surface, but they are confident this is the most likely explanation.

Collapse of the universe is closer than ever before

Posted: 12 Dec 2013 08:30 AM PST

Maybe it happens tomorrow. Maybe in a billion years. Physicists have long predicted that the universe may one day collapse, and that everything in it will be compressed to a small hard ball. New calculations now confirm this prediction -- and they also conclude that the risk of a collapse is even greater than previously thought.

Suicidality test being brought to market

Posted: 12 Dec 2013 06:58 AM PST

A new test should help doctors to decrease the risk of suicidality in patients treated with antidepressants who show certain gene markers. Researchers plan to launch the test immediately as a laboratory developed test. In addition, clinical studies in support of a U.S. Food and Drug Administration submission for market clearance, CE marking and reimbursement will be initiated.

Revolutionary method for gluing gels and biological tissues

Posted: 12 Dec 2013 06:56 AM PST

Researchers have discovered an efficient and easy-to-use method for bonding together gels and biological tissues. Medical researchers have succeeded in obtaining very strong adhesion between two gels by spreading on their surface a solution containing nanoparticles. Until now, there was no entirely satisfactory method of obtaining adhesion between two gels or two biological tissues.

Controlling PCs and tablets with hand movements

Posted: 12 Dec 2013 06:55 AM PST

Scientists are working to develop interaction between themselves and mobiles/ iPads - which does not require touching the display. They have been able to scroll through pages for some time. Now they are working on selecting and moving objects, or saying stop by raising a hand.

Novel bio-inspired method to grow high-quality graphene for high-end electronic devices

Posted: 12 Dec 2013 06:49 AM PST

Researchers have successfully developed an innovative one-step method to grow and transfer high-quality graphene on silicon and other stiff substrates, opening up opportunities for graphene to be used in high-value applications that are currently not technologically feasible.
