Drug Targets Lupus by Tricking Immune System

A new approach shows early promise in fighting the devastating disease. Scientists developing drugs to treat lupus face a daunting set of challenges. The disease, which affects 1.5 million Americans, results when the immune system mistakenly recognizes healthy tissues as dangerous and attacks them, touching off a range of responses. Some patients get arthritis and rashes, others develop heart...

Blog - Capturing "Hot" Electrons to Double Solar Power

Researchers demonstrate that high-energy electrons lost in conventional solar cells can be captured. There's a limit on the conversion efficiency of a conventional solar cell. No matter how it's tweaked, it can only convert 31 percent of the light that hits it into usable electrical current. That's because there's a broad spectrum of wavelengths in sunlight, and some of it has...

Blog - Deformable Liquid Mirrors Could Revolutionise Astronomy

Liquid mirrors are cheaper and easier to make than glass ones. Now a new prototype shows how they can also be deformed to make adaptive optics systems Put a puddle of mercury into a bowl, set it spinning and the liquid will spread out in a thin film across the surface. The result is a concave mirror with a surface so smooth that it rivals anything that astronomers can make out of glass but at a...

Blog - How to Prevent Language Extinction

Two third of the world's languages are endangered. Now a new mathematical model of language competition suggests how to combat the threat The 7 billion inhabitants of Earth currently speak about 6000 different languages. That may seem a healthy multitude but it turns out that just five of these languages dominate. More than half the population speak English, Russian, Mandarin, Hindi and...

Blog - The Problem With Quantum Lithography

Entangled photons can dramatically reduce the feature sizes possible with lithography. At least, that's what physicists had hoped Lithography, the ability to print patterns onto certain materials using light, is one of the enabling technologies of our age. The size of the features that can be defined this way are tiny, limited only by the wavelength of light used to make them, the so-called...

Blog - Quantum Theory Separates Gravitational and Inertial Mass

The equivalence principle is one of the corner stones of general relativity. Now physicists have used quantum mechanics to show how it fails The equivalence principle is one of the more fascinating ideas in modern science. It asserts that gravitational mass and inertial mass are identical. Einstein put it like this: the gravitational force we experience on Earth is identical to the force we would...

Video - Microsoft’s New Display

Microsoft has developed a new type of wedge-shaped lens that precisely controls the direction of light emitted from it. The lens can easily be integrated into a liquid crystal display, and when a camera is added, the system is able to track viewers and project stereoscopic video directly into their eyes. In this demonstration, the system supports tow independent stereoscopic video projects....

Blog - AI That Picks Stocks Better Than the Pros

A computer science professor uses textual analysis of articles from Yahoo Finance to beat the market. The ability to predict the stock market is, as any Wall Street quantitative trader (or quant) will tell you, a license to print money. So it should be of no small interest to anyone who likes money that a new system that works in a radically different way than previous automated trading schemes...
