Scientists teaching machines to make clinical trials more successful

Wed, 04/27/2016 - 13:50
Scientists are teaching computers to figure out why people accept or decline invitations to participate in clinical trials. Recruiting sufficient numbers of participants is a current challenge in medical research that can compromise results or stop some studies altogether. Researchers are using so-called “machine learning” technologies to predict whether patients will participate.

Smarter sensing for the Internet of Things

Wed, 04/27/2016 - 12:24
A sensor node processor for networked sensor applications achieves ultra-low power consumption by using ultra-low voltage operation, hardware acceleration and cognitive sensing techniques.

Thinking outside the sample

Wed, 04/27/2016 - 12:23
Scientists are helping computers learn to tackle big-data problems outside their comfort zones. The framework can be used for numerous applications, they say, including image segmentation, motion segmentation, data clustering, hybrid system identification and image representation.

Stepless control devices with flexible pressure sensors

Wed, 04/27/2016 - 12:13
Silicone is so soft and flexible that it is easily deformed by the pressure of a finger. Researchers have recently created sensors made from this flexible material, making it easier to steplessly control devices. Researchers now present a glove that can measure pressure and a steering wheel that lets the driver control music, light and ventilation at the touch of a finger.

Measuring happiness on social media

Wed, 04/27/2016 - 12:09
Happiness. It's something we all strive for, but how do we measure it--as a country? A global community? Computer scientists used two years of Twitter data to measure users' life satisfaction, a component of happiness.

Theory establishes a path to high-performance 2-D semiconductor devices

Tue, 04/26/2016 - 20:25
Researchers have uncovered a way to overcome a principal obstacle in using two-dimensional (2-D) semiconductors in electronic and optoelectronic devices.

Weighing the pros and cons of mental-health apps

Tue, 04/26/2016 - 18:45
There are more than 165,000 mobile applications available for health care, with the largest category for people with mental-health disorders, managing everything from addiction to depression and schizophrenia. Although in wide use, the efficacy of most of these programs -- software designed for use with a mobile device -- has not undergone rigorous scientific review, say experts.

Providing children with tablets loaded with literacy apps yields positive results

Tue, 04/26/2016 - 17:01
Researchers have been conducting a study to determine whether tablet computers loaded with literacy applications could improve the reading preparedness of young children living in economically disadvantaged communities. In all three cases, study participants' performance on standardized tests of reading preparedness indicated that the tablet use was effective.

Does learning improve when every student gets a laptop?

Tue, 04/26/2016 - 15:06
Schools that provide each student with a laptop computer, as well as the appropriate support for both students and teachers, see significant improvement in academic achievement, a new paper indicates.

Robots may be able to lift, drive, and chat, but are they safe and trustworthy?

Tue, 04/26/2016 - 13:24
Automation experts conclude that the time is ripe for human factors researchers to contribute scientific insights that can tackle the many challenges of human-robot interaction.

Sensitive people more vulnerable to online dating scams

Tue, 04/26/2016 - 13:22
Sensitive and less emotionally intelligent people are more likely to be vulnerable to online dating scams, new research concludes. Over 90 victims of dating scams took part in questionnaires relating to their personality, how they relate to other people, self-esteem and emotional intelligence.

Investigating world’s oldest human footprints with software designed to decode crime scenes

Tue, 04/26/2016 - 13:21
Software has unearthed new information about Laetoli's lost tracks, revealing hints of a previously undiscovered fourth track-maker at the site. The Laetoli tracks were discovered by Mary Leakey in 1976 and are thought to be around 3.6 million years old.

Clinical database to help reduce number of miscarriages

Mon, 04/25/2016 - 18:35
A new national database in England could help relieve the misery of miscarriage for thousands of women. Researchers intend to use data to help discover why some pregnancies fail.

Internet video portals do not control views well

Mon, 04/25/2016 - 18:31
The majority of video reproduction portals on internet, with the exception of YouTube, have quite unsophisticated systems for controlling fraud in the number of views, and some of them even seem to completely lack such systems, according to new research.

The light stuff: A brand-new way to produce electron spin currents

Mon, 04/25/2016 - 18:23
Scientists have demonstrated using non-polarized light to produce in a metal what's called a spin voltage -- a unit of power produced from the quantum spinning of an individual electron.

Rare Earth atoms see the light

Mon, 04/25/2016 - 18:18
Physicists have discovered a promising new route for combined optical and solid-state-based quantum information.

Videogames against malaria: Learn through playing

Mon, 04/25/2016 - 13:55
A malaria "Candy Crush" to research new diagnostic tools involving citizen participation has been developed by researchers. Called MalariaSpot Bubbles, the video game not only allows players to learn, but also to participate in the research of new tools for collaborative diagnosis online.

Videogame addiction linked to ADHD

Mon, 04/25/2016 - 13:55
Young and single men are at risk of being addicted to video games. The addiction indicates an escape from ADHD and psychiatric disorder, suggests a new study.

Measuring river surface flow with image analysis

Mon, 04/25/2016 - 13:53
New software has been developed that can measure the flow rate of rivers using image analysis, called KU-STIV (Kobe University Space-Time Image Velocimetry). This technology makes it easier to obtain accurate data about river flow rates that can be used in strategies for flood risk management.

Trust in the cloud could be pinned to online scoring system
