“By showing the locations of people within a building during hostage situations, fires or other emergencies, radio tomography can help law enforcement and…
New fabrication techniques have enabled the development of on-chip mechanical elements whose dimensions are on the nanometre (one millionth mm) scale. Their…
Even tiny, easily overlooked events can completely change the behavior of a complex system, to the point where there is no apparent order to most natural…
Light readily bounces off obstacles in its path. Some of these reflections are captured by our eyes, thus participating in the visual perception of the objects…
The aluminum-ice, or ALICE, propellant might be used to launch rockets into orbit and for long-distance space missions and also to generate hydrogen for fuel…
In 1931, Paul Dirac, one of the rock stars of the physics world, made the somewhat startling prediction that “magnetic monopoles,” or particles possessing only…
With several local rover connections, the visit will be a homecoming of sorts. Spirit and Opportunity are the two current Mars Exploration Rovers (MER) and are…
Some stars are lonely behemoths, with no surrounding planets or asteroids, while others sport a skirt of attendant planetary bodies. New research published…
Why it matters: A non-invasive electron microscope could shed light on fundamental questions about life and matter, allowing researchers to observe molecules…

So-called 'wake fields' occur during the process of acceleration and can cause particles to fly apart.The particles are travelling at extremely high energies –…
Exploiting quantum mechanics for transmitting information is a tantalizing possibility because it promises secure, high speed communications. Unfortunately,…
This is shown in calculations of the light emission of so-called quark-gluon plasmas, which are created in such collisions for extremely short periods of time….
The goal of the six-year project is to measure the spectra of 1.4 million galaxies and 160,000 quasars, extremely distant objects that shine more brightly than…
NPL, along with collaborators, produced technical reports for the European Space Agency. The conclusions demonstrated that the lasers were a suitable method…
On 3 September, Herschel aimed its telescope at a reservoir of cold gas in the constellation of the Southern Cross near the Galactic Plane. As the telescope…
