Researchers at North Carolina State University have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful and efficient electric cars.

A new phenomenon might make computing devices faster, smaller and much more energy-efficient. Moving so-called skyrmions needs 100,000 times smaller currents than existing technologies and the number of atoms needed for a data bit could be reduced significantly. Now a team of physicists from the Technische Universitaet Muenchen and the University of Cologne developed a simple electronic method for moving and reading these skyrmion data bits

By Jo Marchant of Nature magazine Prion diseases such as bovine spongiform encephalopathy (BSE) and variant Creutzfeldt-Jakob disease (vCJD) are able to jump species much more easily than previously thought.

Every time you boil water in a kettle, you witness a phenomenon known as a phase transition — water transforms from a liquid to a gas, as you can see from the bubbling water and hissing steam. MIT physicists have now observed a much more elusive phase transition: that from a gas into a superfluid, a state where particles flow without any friction.

New study shows Chantix much more likely than other smoking-cessation products to be associated with self-injury and suicide

(PhysOrg.com) -- Berkeley Lab, a partner in the Heavy Ion Fusion Sciences Virtual National Laboratory (HIFS VNL) with Lawrence Livermore and the Princeton Plasma Physics Laboratory, has been a leader in developing a special kind of accelerator for experiments aimed at fusion power, called an induction accelerator. The induction principle is like a string of transformers with two windings, where the accelerator beam itself is the second winding. Induction accelerators can handle ions with suitable kinetic energy at higher currents (many more charged particles in the beam), much more efficiently than RF accelerators.

Quantum computers are largely theoretical devices that would exploit the weird properties of matter at extremely small scales to perform calculations, in some cases much more rapidly than conventional computers can.

By David Fogarty SINGAPORE (Reuters) - Creating crops with deeper roots could soak up much more carbon dioxide from the air, help mankind fight global warming and lead to more drought-tolerant varieties, a British scientist says in a study. [More]

A quantum computer is a device -- still largely theoretical -- that could perform some types of calculations much more rapidly than classical computers. While a bit in a classical computer can represent either 0 or 1, a quantum bit, or qubit, can be in "superposition," representing 0 and 1 at the same time.

Americans are exposed to much more ionizing radiation (the potentially harmful type) than they were 30 years ago. Greater use of medical imaging such as CT scans accounts for almost all the increase. The tests can reveal serious health threats, of course, but they come with risks

Ballengee: If Tiger is to return to form — and win the Masters — he needs to overcome a barrier that is much more mental than physical.

Women who are poor are much more likely to be obese but men are not, U.S.
