The US Army Research Office and the National Security Agency (NSA) are together looking for some answers to their quantum physics questions on quantum computing and cryptography.

Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar power.

The most powerful atom-smasher ever built could make some bizarre discoveries, such as invisible matter or extra dimensions in space, after it is switched on in August. But some critics fear the Large Hadron Collider could exceed physicists' wildest conjectures: Will it spawn a black hole that could swallow Earth?

In recently passed H.R.6063, The U.S. House of Representatives would direct the NASA Administrator to develop plans for a low-cost space mission to rendezvous with the Apophis asteroid and attach a tracking device.

A U.S. general said Sunday he sees nations such as Iran and North Korea racing to produce ICBMs that could carry nuclear warheads.

Nuclear analysts believe that Iran has significantly increased the efficiency of its uranium enrichment operation, a program the United States and other Western powers fear is intended to generate material for nuclear weapons.

An abrupt release of methane, a powerful greenhouse gas, about 635 million years ago from ice sheets that then extended to Earth's low latitudes caused a dramatic shift in climate, triggering a series of events that resulted in global warming and effectively ended the last "snowball" ice age, a UC Riverside-led study reports.

In recent years, global photovoltaic (PV) production has been increasing at a rate of 50 percent per year, so that accumulated global capacity doubles about every 18 months. The PV Moore's law states that with every doubling of capacity, PV costs come down by 20 percent.

A new NASA-led study says human-caused climate change has made an impact on a wide range of Earth's natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa.

Japanese lawmakers voted Friday to allow the military use of space, breaking a decades-old taboo in the officially pacifist country which has an increasingly ambitious space programme. The move will remove any legal obstacles to building more advanced spy satellites.
