(PhysOrg.com) -- Scientists in China and the US have modified a common thermoelectric material to vastly improve its thermoelectric properties. The development could lead to new devices capable of converting waste heat into useful amounts of electricity.

(PhysOrg.com) -- Scientists have demonstrated for the first time that atoms can be guided in a laser beam and possess the same properties as light guided in an optical communications fiber.

It seems impossible: Scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden (Germany) were able to verify with an intermetallic compound of bismuth and nickel that certain materials actually exhibit the two contrary properties of superconductivity and ferromagnetism at the same time.

By Alex Leff PUNTARENAS, Costa Rica (Reuters) - Scientists set off from Costa Rica on Sunday to drill a hole deep under the sea and directly extract rocks from record depths that could add to the understanding of climate change. [More]

You know the UV-ink rubber stamps that night clubs like to stick on your skin? Well, a novel silver nanotech variant of the idea could actually help heal your skin wounds more quickly. Silverware became popular centuries ago partly because it was a precious metal and thus a status symbol, but also because the health qualities of silver have been known since Roman times

A newly developed nanoparticle cream could hold the cure for nickel allergies and skin irritation from metal jewelery. Approximately 10% of the population has a nickel allergy that causes skin irritation when they wear inexpensive metal jewelery or handle coins for an extended period of time.

If the notion of next-generation electronic components made from actual human blood cells chills you, you may not want to read on.

(PhysOrg.com) -- Scientists from Oxford University have mapped a state of matter called 'quantum spin liquid', whose existence was proposed in the 1970s but which has only been observed recently.

(PhysOrg.com) -- Quantum physicists from the University of Innsbruck (Austria) have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show surprising results for the quantum mechanical phenomenon of entanglement.

Turning bedbugs' own pheromones against them. Bed bugs are the scourge of New York, and of other cities as well. And yet, for a number of reasons, the long-awaited War on Bedbugs has yet to arrive

(PhysOrg.com) -- Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have joined with researchers at Stanford University and the SLAC National Accelerator Laboratory to mount a three-pronged attack on one of the most obstinate puzzles in materials sciences: what is the pseudogap?

Fingernail-sized, gemstone-shaped, it's the first device of its kind.

(PhysOrg.com) -- Scientists from The Australian National University have developed an atom laser that behaves exactly like a light laser, opening up new possibilities in things like holograms.

  Scientists have identified a chain of chemical reactions that begins with one gene and prompts the body to absorb fat.
