July 22, 2014 10:15 pm | by The Associated Press | Comments

Target is introducing an app that lets users purchase items after scanning magazine ads with their smartphones. It's the latest offering from retailers looking to boost sales with the use of improving image-recognition technology. Starting this month, the app, called "In a Snap," will recognize...

Protect yourself from identity theft

July 22, 2014 10:15 pm | by The Associated Press | Comments

It's an almost weekly occurrence: On Tuesday, Goodwill said its computer systems may have been hacked, leading to the possible theft of customers' credit and debit card information. The nonprofit agency, which operates 2,900 stores in the U.S., said it is working with federal investigators to look...

Review: Amazon Fire offers new ways to use phones

July 22, 2014 10:15 pm | by Anick Jesdanun - AP Technology Writer - Associated Press | Comments

What I find fascinating about Amazon's Fire phone isn't the gizmos such as the 3-D imagery or the camera scanner that helps you get more information about products. Rather, I like that Amazon is thinking a lot about how phones ought to work. The iPhone and its Android smartphone rivals are so...

Penn study: Understanding graphene's electrical properties on an atomic level

July 22, 2014 4:36 pm | by EurekAlert! | Comments

Graphene, a material that consists of a lattice of carbon atoms, one atom thick, is widely touted as being the most electrically conductive material ever studied. However, not all graphene is the same. With so few atoms comprising the entirety of the material, the arrangement of each one has an impact on its overall function....

X-ray irradiation at a certain dose alters the neuronal cytoskeleton and cytomechanics

July 22, 2014 4:28 pm | by EurekAlert! | Comments

Cranial radiotherapy is one of the most important therapeutic methods for the treatment of various types of primary and metastatic brain tumors. Although conventional photon irradiation has significantly improved the treatment of cancer, the central nervous system is prone to damage after high-dose irradiation....

Self-cooling solar cells boost power, last longer

July 22, 2014 4:24 pm | by EurekAlert! | Comments

Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun. By adding a specially patterned layer of silica glass to the surface of ordinary solar cells ...

A new multi-bit 'spin' for MRAM storage

July 22, 2014 4:12 pm | by EurekAlert! | Comments

Interest in magnetic random access memory (MRAM) is escalating, thanks to demand for fast, low-cost, nonvolatile, low-consumption, secure memory devices. MRAM, which relies on manipulating the magnetization of materials for data storage rather than electronic charges....

Fly-inspired sound detector

July 22, 2014 4:08 pm | by EurekAlert! | Comments

Even within a phylum so full of mean little creatures, the yellow-colored Ormia ochracea fly is distinguished among other arthropods for its cruelty -- at least to crickets. Native to the southeastern U.S. states and Central America, the fly is a most predatory sort of parasite....

The evolution of airplanes

July 22, 2014 3:39 pm | by EurekAlert! | Comments

One of the traditional arguments against Darwinian evolution has been that no one can confirm the process exists because it occurs on a time scale immensely greater than a human lifetime. Adrian Bejan, the J. A. Jones Distinguished Professor of Mechanical Engineering at Duke University, has disagreed with that notion ever since 1996....

Quantum leap in lasers at Dartmouth brightens future for quantum computing

July 22, 2014 2:55 pm | by EurekAlert! | Comments

Dartmouth scientists and their colleagues have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers....

Technique simplifies the creation of high-tech crystals

July 22, 2014 2:42 pm | by EurekAlert! | Comments

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But producing these crystals by current techniques, such as etching them with a precise beam of electrons, is often extremely difficult and expensive....

'Comb on a chip' powers new NIST/Caltech atomic clock design

July 22, 2014 2:38 pm | by EurekAlert! | Comments

Researchers from the National Institute of Standards and Technology (NIST) and California Institute of Technology (Caltech) have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb, or a microcomb....

NASA's Chandra X-ray Observatory celebrates 15th anniversary

July 22, 2014 2:16 pm | by NASA | Comments

Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision....

NIST shows ultrasonically propelled nanorods spin dizzyingly fast

July 22, 2014 12:52 pm | by EurekAlert! | Comments

Vibrate a solution of rod-shaped metal nanoparticles in water with ultrasound and they'll spin around their long axes like tiny drill bits. Why? No one yet knows exactly. But researchers at the National Institute of Standards and Technology (NIST) have clocked their speed—and it's fast....

Seals forage at offshore wind farms

July 22, 2014 12:41 pm | by EurekAlert! | Comments

By using sophisticated GPS tracking to monitor seals' every movement, researchers have shown for the first time that some individuals are repeatedly drawn to offshore wind farms and pipelines. Those man-made structures probably serve as artificial reefs and attractive hunting grounds....
