Doomsday Clock
(Preview)
"Doomsday Clock" moves one minute away from midnight Citing a more "hopeful state of world affairs" in relation to the twin threats posed by nuclear weapons and climate change, the Bulletin of the Atomic Scientists (BAS) is moving the minute hand of its famous Doomsday Clock...

Hill sphere
(Preview)
The Hill sphere is the region of space where an astronomical object's gravity is the dominant force affecting nearby objects. Earth's Hill sphere extends to about 1.5 million kilometres, 0.01 AU or 932,000 miles, from the planet. In more precise terms, the Hill sphere approximates the gravitatio...

NOνA Experiment
(Preview)
Neutrino data to flow in 2010 Physicists may see data as soon as late summer from the prototype for a $278 million science experiment in northern Minnesota that is being designed to find clues to some fundamental mysteries of the universe, including dark matter. But it could take years before the nat...

Gradient index (GRIN) lenses
(Preview)
Duke University engineers have created a new generation of lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail. But the lens they fashioned doesn't look anything like a lens. While traditional lenses are made o...

Nitrogen
(Preview)
Researchers devise new way to cleave nitrogen Prescription drugs, nylon stockings and common fertilizers all have something in common -- bonded atoms of nitrogen and carbon. But any chemist knows creating these bonds is no easy task, as nitrogen in its natural state is paired (N2) and contains a st...

4D electron microscopy
(Preview)
Caltech Scientists Film Photons with Electrons Techniques recently invented by researchers at the California Institute of Technology (Caltech) - which allow the real-time, real-space visualisation of fleeting changes in the structure of nanoscale matter - have been used to image the evanesc...

UV/radiation blocking
(Preview)
Research may lead to better UV/radiation blocking in eye glasses Adding cerium oxide to phosphate glass rather than the commonly used silicate glass may make eye glasses that block ultraviolet light and have increased radiation damage resistance while remaining colourless, according to Penn S...

Battery
(Preview)
Batteries made from plain copier paper could make for future energy storage that is truly paper thin. The approach relies on the use of carbon nanotubes - tiny cylinders of carbon - to collect electric charge. While small-scale nanotube batteries have been demonstrated before, the plain paper app...

Spintronic
(Preview)
An unpopular pigment used by artists in the 18th Century could lead to more energy efficient, faster computers.
Cobalt green, as the dye is known, has been tested by a US team who believe it could be used in "spintronic" devices.
Spintronics involves manipulating the magnetic properties of e...

Molecular photoswitches
(Preview)
Scientists have shown off an effect not unlike that of the "phasers" in the show Star Trek - but it only works on tiny worms called nematodes. They used a special molecule that, when exposed to ultraviolet (UV) light, changes its shape. When the worms were fed this molecule and then exposed...

Electro-luminescence
(Preview)
Electron and hole modulating electrodes in organic light emitting diodes Certain organic thin films emit light under the action of electric field. If such organic thin film whose thickness is of the order of wavelength of light is sandwiched between a cathode and an anode and applied with a voltage...
