Loans Applications? New techniques to measure social bias in software

Thu, 08/17/2017 - 20:20
Today, banks are increasingly using software to decide who will get a loan, courts to judge who should be denied bail, and hospitals to choose treatments for patients. These uses of software make it critical that the software does not discriminate against groups or individuals, say computer science researchers.

AI implications: Engineer's model lays groundwork for machine-learning device

Thu, 08/17/2017 - 20:20
In what could be a small step for science potentially leading to a breakthrough, an engineer has taken steps toward using nanocrystal networks for artificial intelligence applications.

Older users like to snoop on Facebook, but worried others might snoop on them

Thu, 08/17/2017 - 17:11
Older adults are drawn to Facebook so they can check out pictures and updates from family and friends, but may resist using the site because they are worried about who will see their own content, according to a team of researchers.

Computer approaches human skill for first time in mapping brain

Thu, 08/17/2017 - 13:27
Scientist, for the first time, have developed a computer algorithm that is nearly as accurate as people are at mapping brain neural networks -- a breakthrough that could speed up the image analysis that researchers use to understand brain circuitry.

Telemedicine as effective as in-person care for Parkinson's disease

Wed, 08/16/2017 - 20:06
Telemedicine can successfully deliver quality care, new findings from a nationwide program that links neurologists with patients with Parkinson's disease in their homes via video conferencing shows. The study points to a new way to improve care for people who suffer from the disease, but may have not have access to a neurologist.

Superconductivity research reveals potential new state of matter

Wed, 08/16/2017 - 17:47
A potential new state of matter is being reported with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common. The ability to find similarities and differences among classes of materials with phenomena such as this helps researchers establish the essential ingredients that cause novel functionalities such as superconductivity.

Scientists use magnetic fields to remotely stimulate brain -- and control body movements

Wed, 08/16/2017 - 17:46
Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremities -- an achievement that could lead to advances in studying and treating neurological disease.

Computer scientists use music to covertly track body movements, activity

Wed, 08/16/2017 - 17:46
Researchers have demonstrated how it is possible to transform a smart device into a surveillance tool that can collect information about the body position and movements of the user, as well as other people in the device's immediate vicinity.

Study: Playing smartphone app aids concussion recovery in teens

Wed, 08/16/2017 - 15:01
Generally, after suffering a concussion, patients are encouraged to avoid reading, watching TV and using mobile devices to help their brains heal. But new research shows that teenagers who used a mobile health app once a day in conjunction with medical care improved concussion symptoms and optimism more than with standard medical treatment alone.

Trying to resist the urge to splurge? Ditch the smartphone

Wed, 08/16/2017 - 14:02
You are more likely to indulge in guilty pleasures when shopping online with a touchscreen versus a desktop computer, according to research.

Smart electrical grids more vulnerable to cyber attacks

Wed, 08/16/2017 - 14:02
Electricity distribution systems in the USA are gradually being modernized and transposed to smart grids, which make use of two-way communication and computer processing. This is making them increasingly vulnerable to cyber attacks.

High-quality online video with less rebuffering

Tue, 08/15/2017 - 16:05
In experiments, Pensieve could stream video with 10 to 30 percent less rebuffering than other approaches, and at levels that users rated 10 to 25 percent higher on key 'quality of experience' metrics.

Computer tech: 'Organismic learning' mimics some aspects of human thought

Tue, 08/15/2017 - 15:11
