New project helps researchers build a biomedical knowledgebase

Thu, 04/14/2016 - 21:00
Over the past 10 years, the volume and rate of biomedical research has increased dramatically, leading to a rapid growth in biomedical knowledge. However, this knowledge is currently fragmented across countless resources. Scientists have integrated biomedical data into Wikidata, a public, editable database where researchers can easily link genes, proteins and more.

A single-atom magnet breaks new ground for future data storage

Thu, 04/14/2016 - 18:47
Scientists have built a single-atom magnet that is the most stable to date. The breakthrough paves the way for the scalable production of miniature magnetic storage devices.

Coding, computers help spot methane, explosives

Thu, 04/14/2016 - 16:20
A modern twist on classic mass spectrometers could soon help detect rogue methane leaks, hidden explosives and much more. With the help of modern data analytics, researchers show that a technology using a so-called 'coded aperture' can shrink these devices while maintaining their performance.

Research team revs up connected-vehicle technology

Thu, 04/14/2016 - 13:55
Cars, fire trucks and traffic signals are connected on live streets in an Arizona community, where engineering researchers are fine-tuning their technology and demonstrating its power to save lives and put an end to sitting at an empty intersection, waiting for the light to change.

Few consumers penalize companies after data breach, study finds

Thu, 04/14/2016 - 12:15
Notices of personal data breaches have become an alarmingly common occurrence for American consumers. The first survey to examine consumers' attitudes about such data hacks finds that few people stop doing business with a company after a hack and most report accepting offers to enroll in free credit monitoring services. More than three-quarters of those surveyed said they were highly satisfied with the company's post-breach response.

Sexist video games decrease empathy for female violence victims

Wed, 04/13/2016 - 19:10
Young male gamers who strongly identify with male characters in sexist, violent video games show less empathy than others toward female violence victims, a new study found.

Using data to protect coral reefs from climate change

Wed, 04/13/2016 - 18:01
Coral reefs are early casualties of climate change, but not every coral reacts the same way to the stress of ocean warming. Researchers have developed the first-ever quantitative 'global index' detailing which of the world's coral species are most susceptible to coral bleaching and most likely to die. Based on historical data, the index can be used to compare the bleaching responses of the world's corals and to predict which corals may be most affected by future bleaching events.

Location data on two apps enough to identify someone, says study

Wed, 04/13/2016 - 18:01
A team of researchers demonstrate that location-tagged posts on just two social media apps are enough to link accounts held by the same person and identify him or her, raising new concerns about mobility metadata.

Computers in your clothes? A milestone for wearable electronics

Wed, 04/13/2016 - 17:59
Researchers who are working to develop wearable electronics have reached a milestone: They are able to embroider circuits into fabric with 0.1 mm precision -- the perfect size to integrate electronic components such as sensors and computer memory devices into clothing.

Are humans the new supercomputer?

Wed, 04/13/2016 - 17:58
Online computer games allow gamers to solve a class of problems in quantum physics that cannot be easily solved by algorithms alone. Citizen science games have already proved successful in advancing scientific endeavours, but had not previously been applied to quantum physics. A Danish team of scientists find, that players succeed where purely numerical optimization fails, and they present a new optimization method based on the observed player strategies that outperforms prominent, established numerical methods.

Elusive state of superconducting matter discovered after 50 years

Wed, 04/13/2016 - 17:57
Scientists have produced the first direct evidence of a state of electronic matter first predicted by theorists in 1964 -- a 'Cooper pair density wave.' The discovery may provide key insights into the workings of high-temperature superconductors.

Robots could get 'touchy' with self-powered smart skin

Wed, 04/13/2016 - 15:33
Smart synthetic skins have the potential to allow robots to touch and sense what's around them, but keeping them powered up and highly sensitive at low cost has been a challenge. Now scientists report a self-powered, transparent smart skin that is simpler and less costly than many other versions that have been developed.

Robird to make its first flight at airports

Wed, 04/13/2016 - 12:45
A "Robird" will make its first flights at an airport location in February. The Robird is designed to scare away birds at airports and waste processing plants.

Predicting gentrification through social networking data

Wed, 04/13/2016 - 01:11
Data from location-based social networks may be able to predict when a neighbourhood will go through the process of gentrification, by identifying areas with high social diversity and high deprivation.

Benefits to using telehealth with ASD families

Tue, 04/12/2016 - 20:03
Parents with children on the autism spectrum are able to have a specialist address challenging behavior in these children by interacting over the computer, too -- and at less than half of the cost of receiving similar care in person, suggests a new report.

Sorry kids, seniors want to connect and communicate on Facebook, too

Tue, 04/12/2016 - 17:47
Older adults, who are Facebook's fastest growing demographic, are joining the social network to stay connected and make new connections, just like college kids who joined the site decades ago, according to researchers.

Mapping software tracks threats to endangered species

Tue, 04/12/2016 - 17:26
Modelling software and satellite imagery can be used to rapidly predict the movements of endangered species in remote or inaccessible regions, a study shows. Scientists used the images and software to assess habitat loss restricting the mobility of Peru's endangered San Martin titi monkey and identify the 10 percent of remaining forests best suited for the conservation of essential movement corridors. Comprehensive on-the-ground assessments would have taken longer and been cost-prohibitive.

Long-range secure quantum communication system developed

Tue, 04/12/2016 - 17:26
A novel approach to the construction of quantum communication systems has been developed for secure data exchange. The experimental device based on the results of the research is capable of transmitting single-photon quantum signals across distances of 250 kilometers or more, which is on par with other cutting edge analogues.

Commonly used strategy for website protection might not work

Tue, 04/12/2016 - 14:49
Cloud-based security providers commonly use DNS redirection to protect customers' websites. The success of this strategy depends on shielding the website's original IP address. Computer scientists have now revealed that the IP address can be retrieved in more than 70 percent of the cases. This means that the DNS redirection security mechanism can easily be bypassed.

Autonomous vehicles cannot be test-driven enough miles to demonstrate their safety

Tue, 04/12/2016 - 14:49
Autonomous vehicles would have to be driven hundreds of millions of miles and, under some scenarios, hundreds of billions of miles to create enough data to clearly demonstrate their safety, according to a new report. Under even the most-aggressive test driving assumptions, it would take existing fleets of autonomous vehicles tens and even hundreds of years to log sufficient miles to adequately assess the safety of the vehicles when compared to human-driven vehicles, according to the analysis.
