Fusion, anyone? Not quite yet, but researchers show just how close we've come
The dream of igniting a self-sustained fusion reaction with high yields of energy, a feat likened to creating a miniature star on Earth, is getting closer to becoming reality, according the authors of a new ...
Transparent aluminium is 'new state of matter'
(PhysOrg.com) -- Oxford scientists have created a transparent form of aluminium by bombarding the metal with the world’s most powerful soft X-ray laser. 'Transparent aluminium' previously only existed in ...
Quantum mechanics may explain how humans smell

Roll over Einstein: Law of physics challenged (Update 3)
One of the very pillars of physics and Einstein's theory of relativity - that nothing can go faster than the speed of light - was rocked Thursday by new findings from one of the world's foremost laboratories.
UCF physicist says Hollywood movies hurt students' understanding of science
Movies such as Spiderman 2 and Speed generate excitement among audiences with their cool special effects. But they also defy the laws of physics, contributing to students’ ignorance about science.
Negative Refraction of Visible Light Demonstrated; Could Lead to Cloaking Devices
For the first time, physicists have devised a way to make visible light travel in the opposite direction that it normally bends when passing from one material to another, like from air through water or glass. The phenomenon ...
Time to overhaul Newton's theory of gravitation? Galaxy cluster models cast doubt on dark matter
For almost 75 years, astronomers have believed that the Universe has a large amount of unseen or ‘dark’ matter, thought to make up about five-sixths of the matter in the cosmos. With the conventional theory of gravitation, ...

New aluminum-rich alloy produces hydrogen on-demand for large-scale uses
Purdue University engineers have developed a new aluminum-rich alloy that produces hydrogen by splitting water and is economically competitive with conventional fuels for transportation and power generation.
V-shaped solar cells could lead to better efficiency
Rapid-fire: Electrical circuit may bring Sandia Z to fusion sooner
An electrical circuit that should carry enough power to produce the long-sought goal of controlled high-yield nuclear fusion and, equally important, do it every 10 seconds, has undergone extensive preliminary ...
The New New Math of String Theory
At the beginning of the last century, Albert Einstein posited a now famous theory that forever linked geometry and fundamental physics. According to general relativity, spacetime is curved, and that curvature ...
