In nearly 13 printed pages with a host of calculations, research may have solved the information loss paradox that has perplexed physicists for the past 40 years.

The mess of electrical cables that recharge our laptops, mobile phones and PDAs could soon disappear altogether -- at least according to a team of US physicists, who have shown how power can be transmitted without wires using special "resonant" antennas.

Researchers at Delft University of Technology have succeeded in carrying out calculations with two quantum bits, the building blocks of a possible future quantum computer.

Most people have heard absolute zero described as the lowest possible temperature, but what does that mean? Is it really the coldest cold, or just the lowest temperature that we can measure?

To observe the motion of an electron – an elementary particle with a mass that is one billionth of a billionth of a billionth of a gram – has been considered to be impossible.

A team of University of British Columbia researchers has contributed to the greatest advancement in superconductor research in a decade by "growing" the purest samples of superconductors to date.

University of Michigan astronomers combined light from four widely separated telescopes to produce the first picture showing surface details on a sun-like star beyond our solar system.

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with light while also making the atoms do things that light jus

Researchers have developed a technique to create tiny, highly efficient light-emitting diodes (LEDs) from nanowires.

“Solid light will help us build the technology of this century,” says Dr Andrew Greentree of the School of Physics at the University of Melbourne.
