Online media use shows strong genetic influence

Mon, 01/23/2017 - 20:14
Online media use such as social networking and gaming could be strongly influenced by our genes, according to a new study.

Microscopic submarines for your stomach

Mon, 01/23/2017 - 17:55
Tiny 'submarines' that speed independently through the stomach, use gastric acid for fuel (while rapidly neutralizing it), and release their cargo precisely at the desired pH: Though it may sound like science fiction, this is a new method for treating stomach diseases with acid-sensitive drugs. The technique is based on proton-driven micromotors with a pH-dependent polymer coating that can be loaded with drugs.

Improving prognoses for a sustainable future

Mon, 01/23/2017 - 14:08
Whether it's electric automobiles, renewable energy, carbon tax or sustainable consumption, sustainable development requires strategies that meet people's needs without harming the environment. Before such strategies are implemented, their potential impact on environment, economy, and society needs to be tested. These tests can be conducted with the help of computer models that depict future demographic and economic development and that examine the interplay between industry and the climate. But computer models play a significant role in environmental policy, but offer only a partial picture of the industrial system, say experts.

Your Android device's Pattern Lock can be cracked within five attempts

Mon, 01/23/2017 - 14:08
The popular Pattern Lock system used to secure millions of Android phones can be cracked within just five attempts -- and more complicated patterns are the easiest to crack, security experts reveal.

Mummy visualization impresses in computer journal

Mon, 01/23/2017 - 14:07
Using visualization technology, visitors to the British Museum can reveal the murder of the mummified Geberlein Man, 5,500 years ago.

Processing speed training can improve cognitive ability, lift depression in the elderly

Sat, 01/21/2017 - 00:38
A new Processing Speed Training Game (PSTG) has been developed for a Tablet PC, which they say can significantly improve processing speed and inhibition among healthy older adults, while also reducing their depressive moods when played regularly.

App improves medication adherence for heart stent patients

Fri, 01/20/2017 - 22:10
A tablet computer application helped heart patients with drug-eluting stents take their medications correctly, a study has found. Researchers found that patients in the intervention group had a 10 percent higher medication possession ratio than patients in the control group.

Study uses social media, internet to forecast disease outbreaks

Thu, 01/19/2017 - 21:15
When epidemiological data are scarce, social media and Internet reports can be reliable tools for forecasting infectious disease outbreaks, according to a study.

Seeking structure with metagenome sequences

Thu, 01/19/2017 - 21:15
Scientists now report that structural models have been generated for 12 percent of the protein families that had previously had no structural information available.

System links data scattered across files, for easy querying

Thu, 01/19/2017 - 21:15
System finds and links related data scattered across digital files, for easy querying and filtering.

Your 'anonmyized' web browsing history may not be anonymous

Thu, 01/19/2017 - 18:45
Researchers have written computer programs that found patterns among anonymized data about web traffic and used those patterns to identify individual users. The researchers note web users with active social media are vulnerable to the attack.

Making AI systems that see the world as humans do

Thu, 01/19/2017 - 16:09
An artificial intelligence system has been developed that performs at human levels on a standard intelligence test.

One in five adults secretly access their friends' Facebook accounts

Thu, 01/19/2017 - 15:02
Most people are concerned about the prospect of their social media accounts being hacked, but a new study finds that it's actually people we know who frequently access our accounts without our permission.

Telecommuting extends the work week, at little extra pay

Thu, 01/19/2017 - 14:58
Telecommuting may not be as advantageous as employees think. A new study shows working from home adds extra hours to the work week, at little additional pay. The findings may change workers' perceptions of the value of telecommuting and could spur employers to better define the work-at-home workday.

Graphene's sleeping superconductivity awakens

Thu, 01/19/2017 - 13:46
The intrinsic ability of graphene to superconduct (or carry an electrical current with no resistance) has been activated for the first time. This further widens the potential of graphene as a material that could be used in fields such as energy storage, high-speed computing, and molecular electronics.

Chip-sized, high-speed terahertz modulator raises possibility of faster data transmission

Thu, 01/19/2017 - 13:40
Engineers have invented a chip-sized, high-speed modulator that operates at terahertz (THz) frequencies and at room temperature at low voltages without consuming DC power. The discovery could help fill the “THz gap” that is limiting development of new and more powerful wireless devices that could transmit data at significantly higher speeds than currently possible.

Soft robot helps the heart beat

Wed, 01/18/2017 - 19:37
A customizable soft robot that fits around a heart and helps it beat has now been developed by researchers, potentially opening new treatment options for people suffering from heart failure.

Which facebook 'friends' help most when looking for a job? Depends where you live in the world

Wed, 01/18/2017 - 17:57
Research used anonymous Facebook data from almost 17 million social connections in 55 countries to determine that the role of weak and strong ties in job searches is important around the world, but the value of a single strong tie is even more important for job seekers in countries with pronounced income inequality.

Heartbeat could be used as password to access electronic health records

Wed, 01/18/2017 - 17:52
Researchers have devised a new way to protect personal electronic health records using a patient's own heartbeat.

Glass's off-kilter harmonies

Wed, 01/18/2017 - 15:38
The transport of heat in amorphous materials is largely determined by the behavior of phonons -- quasiparticles associated with the collective vibrations of atoms. Researchers have now developed a new way to calculate the heat contribution of phonons using computer simulations. Using the Stampede supercomputer at the Texas Advanced Computing Center, they modeled amorphous silicon -- glass -- providing new insights into a material that is critical for energy efficiency.
