Self-strengthening nanocomposite gets stronger from repeated stress

Researchers at Rice University have created a synthetic material that gets stronger from repeated stress, much like the body strengthens bones and muscles

Neurons grow into semiconductor tubes: future intelligent chips?

Researchers at the University of Wisconsin, Madison, led by Minrui Yu, have successfully induced nerve cell tendrils to grow through semiconductor tubes

Nano-electrodes may lead to phones that charge in seconds, electric cars in minutes

Researchers at the University of Illinois at Urbana-Champaign have developed a three-dimensional nanostructure for battery cathodes that allows for dramatically

Quantum no-hiding theorem experimentally confirmed for first time

(PhysOrg.com) -- In the classical world, information can be copied and deleted at will. In the quantum world, however, the conservation of quantum information means that information cannot be created nor destroyed. This concept stems from two fundamental theorems of quantum mechanics: the no-cloning theorem and the no-deleting theorem.

'Light sheets' image life in 3d

A technique to image living cells in action, in an unprecedented mix of detail in both time and space, is described by researchers.

New kinds of superconductivity? physicists demonstrate coveted 'spin-orbit coupling' in atomic gases

Physicists have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to quantum computing, next-generation

Black holes: a model for superconductors?

Physicists at the University of Illinois at Urbana-Champaign have shown how charged black holes can be used to model the behavior of interacting electrons

The quantum singularity

A paper describing an experiment that, if it worked, would offer strong evidence that quantum computers can do things that classical computers can’t

New personalized therapy causes cancer cells to kill themselves

A physician-researcher has developed a personalized therapy to treat a wide range of cancers. The treatment is based on a naturally occurring human enzyme that has been genetically modified to fool cancer cells into killing themselves.

Time travel experiment demonstrates how to avoid the grandfather paradox

(PhysOrg.com) -- Among the many intriguing concepts in Einstein’s relativity theories is the idea of closed timelike curves (CTCs), which are paths in spacetime that return to their starting points. As such, CTCs offer the possibility of traveling back in time. But, as many science fiction films have addressed, time travel is full of potential paradoxes. Perhaps the most notable of these is the grandfather paradox, in which a time traveler goes back in time and kills her grandfather, preventing her own birth.

Stronger than steel, novel metals are moldable as plastic

Imagine a material that's stronger than steel, but just as versatile as plastic, able to take on a seemingly endless variety of forms. For decades, materials scientists have been trying to come up with just such an ideal substance, one that could be molded into complex shapes with the same ease and low expense as plastic but without sacrificing the strength and durability of metal.
