New method to detect prize particle for future quantum computing

Wed, 09/10/2014 - 12:33
Scientists have uncovered a new method to detect Majorana particles, a key element for a next-generation quantum computing platform. Quantum computing relies on the laws of quantum mechanics to process vast amounts of information and calculations simultaneously, with far more power than current computers. However, development of quantum computers has been limited as researchers have struggled to find a reliable way to increase the power of these systems, a power measured in Q-Bits.

New map tool identifies patterns of racial diversity across the U.S.

Tue, 09/09/2014 - 20:23
Geography researchers have developed a large-scale mapping technique to track a variety of demographic data across the United States, including researching populations based on gender, race and economic diversity. Details on the technique behind the new, high resolution, grid-based map of U.S. demographics are now available online.

An evolutionary approach to epidemics

Tue, 09/09/2014 - 17:08
An evolutionary analysis of public health data during a major disease outbreak, such as bird flu, E. coli contamination of food or the current Ebola outbreak could help the emergency services plan their response and contain the disease more effectively.

Weekly text message could encourage healthier food choices, new study shows

Tue, 09/09/2014 - 15:36
Many people are unaware that the US Food and Drug Administration's mandated nutrition labels are based on a 2,000-calorie-a-day diet, but a simple weekly text message reminder can greatly improve that awareness, according to a new study.

Texting gives a voice to community members

Tue, 09/09/2014 - 15:33
If you want to learn more about the people in urban communities, save a stamp on mailing a survey. Just text them. A new pilot study among low-income African-Americans in Detroit suggests that there is a clear preference on how residents choose to communicate -- whether it's by researchers asking questions for a health study or community advocates gauging resource needs. They want you to talk to them through their phones.

Squeezed quantum communication: Flashes of light in quantum states transmitted through atmosphere

Tue, 09/09/2014 - 15:33
Scientists have sent a pulse of bright light in a particularly sensitive quantum state through 1.6 kilometers of air. This quantum state, which they call squeezed, was maintained, which is something many physicists thought to be impossible. Eavesdropping on a message protected by quantum cryptography cannot be done without being noticed.

Smart headlights spare the eyes of oncoming drivers

Tue, 09/09/2014 - 15:33
A smart headlight enables drivers to take full advantage of their high beams without fear of blinding oncoming drivers or suffering from the glare that can occur when driving in snow or rain at night.

Researchers advance artificial intelligence for player goal prediction in gaming

Tue, 09/09/2014 - 15:33
Researchers have developed artificial intelligence software that is significantly better than any previous technology at predicting what goal a player is trying to achieve in a video game. The advance holds promise for helping game developers design new ways of improving the gameplay experience for players.

Insight into future of ultra-HDTV live stream technology

Tue, 09/09/2014 - 15:31
Pioneering research into making ultra-high definition TV (UHDTV) available to the masses will be showcased at the world’s biggest international broadcasting event this week.

Buckyballs and diamondoids in tiny electronic gadget: Two exotic types of carbon form molecule for steering electron flow

Tue, 09/09/2014 - 13:38
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

A system that facilitates malware identification in smartphones

Tue, 09/09/2014 - 13:36
Researchers have developed a tool to help security analysts protect markets and users from malware. This system allows a large number of apps to be analyzed in order to determine the malware's origins and family.

No need to leave home: New system of tele-medical assistance for people with mobility problems

Mon, 09/08/2014 - 17:52
Medical researchers have designed a remote medical care system that supports the rehabilitation of people with spasticity, an alteration of the nervous system related to increased tone muscle making motor skills difficult or impossible for those affected.

Layered graphene sandwich for next generation electronics

Mon, 09/08/2014 - 13:36
Sandwiching layers of graphene with white graphene could produce designer materials capable of creating high-frequency electronic devices, scientists have found.

Highly automated live cell imaging speeds up search for new drugs

Mon, 09/08/2014 - 13:36
A new software platform supports the complete work process of finding new pharmaceutical agents in cancer research and tissue analysis. The software was developed specifically for high content analysis of live cell imaging data that monitor and record the complete life cycle of cells. The particular challenge for image analysis here is to detect the different phases of cell modification and cell division, and to record their temporal relationship.

Social networking can help people lose weight, study shows

Mon, 09/08/2014 - 13:35
Social networking programs designed to help people lose weight could play a role in the global fight against obesity, according to research. Obesity is an increasing issue in developed and developing countries, contributing to other diseases such as diabetes, cardiovascular disease, cancer and mental health problems and resulting in rising costs for health services.
