Researchers have developed a new system that repairs dangerous software bugs by automatically importing functionality from other, more secure applications.
A student has developed a computerized learning system that can detect emotional sentiments, such as sarcasm and irony, in text messages and emails. It could help detect content that suggests suicidal ideations, or other "calls for help.”
With the advent of video games, a frequently asked question has been whether we get as engrossed in them emotionally as we do when we see a scary movie. The answer is yes and in new ways, according to new research.
As yet another music streaming service comes online to rival the countless available outlets for so many different genres, a new approach to classifying music to make archiving, sorting and music discovery easier.
Social-networking sites such as Facebook can help students learn scientific literacy and other complex subjects that often receive short shrift in today's time-strapped classrooms.
A new ultrasonic fingerprint sensor measures 3-D image of your finger's surface and the tissue beneath it -- enhancing biometrics and information security for smartphones and other devices. Fingerprint sensor technology currently used in smartphones like the iPhone 6 produces a two-dimensional image of a finger's surface, which can be spoofed fairly easily with a printed image of the fingerprint. A newly developed ultrasonic sensor eliminates that risk by imaging the ridges and valleys of the fingerprint's surface, and the tissue beneath, in three dimensions.
Researchers have developed a new informatics technology that analyzes existing data repositories of protein modifications and 3D protein structures to help scientists identify and target research on "hotspots" most likely to be important for biological function.
New research identifies the types of investors who are vigilant about corporate fraud, but finds that most of those investors are tracking the wrong red flags -- meaning the warning signs they look for are clear only after it's too late to protect their investment.
The day will officially be a bit longer than usual on Tuesday, June 30, 2015, because an extra second, or 'leap' second, will be added.
A simple new computerized game could help people control their snacking impulses and lose weight. Psychologists report that participants lost an average of 0.7kg and consumed around 220 fewer calories a day whilst undergoing the week of training.
New strategies for using electronic health records (EHRs) to treat patients with chronic kidney disease have been outlined by investigators. Their recommendations may help clinicians and hospitals better manage individual patients with chronic conditions and identify groups of patients most likely to benefit from different treatment strategies.
While transparency, openness and reproducibility are readily recognized as vital features of science and embraced by scientists as a norm and value in their work, a growing body of evidence suggests that those qualities are not necessarily evident today. Scientists have now announced guidelines to further strengthen transparency and reproducibility practices in science research reporting.
A computational model that could enhance understanding, diagnosis and treatment of pressure ulcers related to spinal cord injury has been devised by investigators. The team also described results of virtual clinical trials that showed that for effective treatment of the lesions, anti-inflammatory measures had to be applied well before the earliest clinical signs of ulcer formation.
Scientific controversies, from problems replicating results - such as with the now debunked association between autism and MMR vaccines -- to researcher misconduct and sensationalism, have led to speculation of 'trouble at the lab,' as the Economist put it. Top scientists have now examine ways to return to high scientific standards.
Photonics researchers have increased the maximum power -- and therefore distance -- at which optical signals can be sent through optical fibers. This advance has the potential to increase the data transmission rates for the fiber optic cables that serve as the backbone of the Internet, cable, wireless and landline networks. The new study presents a solution to a long-standing roadblock to increasing data transmission rates in optical fiber.
CuPID is striving to provide personalized rehabilitation for patients with Parkinson's disease who experience gait disturbances. It is a home-based personalized rehabilitation tool in the form of a smartphone app that harnesses wearable sensors, audio biofeedback, and external cuing to provide intense motivational training tailored to each patient.
Comment sections on websites continue to be an environment for trolls to spew racist opinions. The impact of these hateful words shouldn't have an impact on how one views the news or others, but that may not be the case. A recent study found that exposure to prejudiced online comments can increase people's own prejudice, and increase the likelihood that they leave prejudiced comments themselves.
Augmented-reality head-up displays (AR-HUDs) that present digital images on windshields to alert drivers to everything from possible collisions to smart phone activity, are meant to make driving safer. But researchers say they are a threat to safety, as drivers frequently need to divide their attention to deal with this added visual information.
A pioneering new technique to produce high-quality, low cost graphene could pave the way for the development of the first truly flexible 'electronic skin,' that could be used in robots.
Computer scientists are developing new adaptive mobile technology that could enable blind and visually-impaired people to ‘see’ through their smartphone or tablet. The team plans to use color and depth sensor technology inside new smartphones and tablets, like the recent Project Tango by Google, to enable 3D mapping and localisation, navigation and object recognition.
