(PhysOrg.com) -- Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010.

For more than 150 years, spark plugs have powered internal combustion engines. Automakers are now one step closer to being able to replace this long-standing technology with laser igniters, which will enable cleaner, more efficient, and more economical vehicles.

(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.

In 1964, physicist Richard Feynman delivered a series of lectures titled “On the Nature of Physical Law.” Feynman delivered these seven one-hour lectures at Cornell in 1964, and the BBC taped them.

Researchers at the University of California, Santa Barbara, say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new generation of high-performance, energy-efficient lighting that could replace incandescent and fluorescent bulbs.

Using well-known patterned media, a team of researchers in France has figured out a way to double the areal density of information by essentially cutting the magnetic media into small pieces and building a "3D tower" out of it.

Invisibility cloaks are seemingly futuristic devices capable of concealing very small objects by bending and channeling light around them.

University of California-Irvine researcher Zhihong Lin is using the Jaguar supercomputer at Oak Ridge National Laboratory to study fusion reactions, which produce helium from hydrogen and release energy in the process, in hopes of igniting ITER, an experimental fusion reactor being built in southern France.

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.

(PhysOrg.com) -- "When you pick up a spoon with your fingers, you are able to move it from side to side and rotate it too by moving thumb and forefinger in opposition," Iain Anderson tells PhysOrg.com. Your hand is a soft machine

Quantum mechanical methods can now be used to study gravity: At the Vienna University of Technology (TU Vienna), a measurement method was developed, which allows to test the fundamental theories of physics.

Israel's cabinet on Sunday announced it had approved the country's membership in the European Organisation for Nuclear Research, becoming the research group's first non-European delegation.

If a new development from labs at MIT pans out as expected, someday the entire surface area of a building’s windows could be used to generate electricity — without interfering with the ability to see through them.

(PhysOrg.com) -- Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat.

An International team of scientists in the XENON collaboration, including several from the Weizmann Institute, announced on Thursday the results of their search for the elusive component of our universe known as dark matter. This search was conducted with greater sensitivity than ever before.
