Spiraling light, nanoparticles, and insights into life's structure

November 20, 2014 11:47 am | by EurekAlert! | Comments

As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it. Scientists know ...

Two new baryon particles discovered

November 20, 2014 10:38 am | by EurekAlert! | Comments

Today an international team of researchers announced the discovery of two new particles in the baryon family, which makes them cousins of the familiar proton and neutron. The LHCb collaboration at CERN, the European Organization for Nuclear Research ...

Pac-Man instead of patch: Using video games to improve lazy eye, depth perception

November 20, 2014 10:35 am | by EurekAlert! | Comments

Scientists have created video games that add an important element of fun to the repetitive training needed to improve vision in people - including adults - with a lazy eye and poor depth perception. The training tools, including a Pac-Man-style ...

A path to brighter images and more efficient LCD displays

November 20, 2014 10:25 am | by EurekAlert! | Comments

University of Utah engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light. Polarizers are indispensable in ...

Image-recognition software greatly improves web searches

November 19, 2014 5:37 pm | by EurekAlert! | Comments

Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before. The new system, which was tested on photos and is now ...

'Cloaking' device uses ordinary lenses to hide objects

November 19, 2014 2:16 pm | by EurekAlert! | Comments

Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways--some simple and some involving new technologies--to hide objects from view. The latest effort, developed at the University of Rochester ...

Could object in space be a jettisoned black hole?

November 19, 2014 2:10 pm | by EurekAlert! | Comments

In his general theory of relativity, Albert Einstein predicted that there are such things as gravitational waves. In fact, the very existence of these waves is the linchpin of the entire theory. Despite the great lengths that physicists have gone to in ...

An alternative to the 'Turing Test' for artificial intelligence

November 19, 2014 2:05 pm | by EurekAlert! | Comments

A Georgia Tech professor is offering an alternative to the celebrated "Turing Test" to determine whether a machine or computer program exhibits human-level intelligence. The Turing Test - originally called the Imitation Game - was proposed by ...

Paper electronics could make health care more accessible

November 19, 2014 1:36 pm | by EurekAlert! | Comments

Flexible electronic sensors based on paper -- an inexpensive material -- have the potential to some day cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost ...

Could hydrogen vehicles take over as the 'green' car of choice?

November 19, 2014 1:33 pm | by EurekAlert! | Comments

Now that car makers have demonstrated through hybrid vehicle success that consumers want less-polluting tailpipes, they are shifting even greener. In 2015, Toyota will roll out the first hydrogen fuel-cell car for personal use that emits only ...

Preparing for an energy-constrained future

November 19, 2014 1:31 pm | by EurekAlert! | Comments

Some time this century, the era of cheap and abundant energy will end, and Western industrial civilization will likely begin a long, slow descent toward a resource-limited future characterized by "involuntary simplicity." That's the picture painted by ...

Spooky alignment of quasars across billions of light-years

November 19, 2014 1:25 pm | by EurekAlert! | Comments

Quasars are galaxies with very active supermassive black holes at their centres. These black holes are surrounded by spinning discs of extremely hot material that is often spewed out in long jets along their axes of rotation. Quasars can shine more ...
