Software-based system improves the ability to determine the cause of ischemic stroke

Software-based system improves the ability to determine the cause of ischemic stroke
Determining the cause of an ischemic stroke -- one caused by an interruption of blood supply -- is critical to preventing a second stroke and is a primary focus in the evaluation of stroke patients. But despite that importance, physicians have long lacked a robust and objective means of doing so. Now a team of investigators at the Athinoula A. Martinos Center for Biomedical Imaging at the Massachusetts General Hospital (MGH) and the MGH Stroke Service have developed a software package that provi…

Desktop scanners can be hijacked to perpetrate cyberattacks

Desktop scanners can be hijacked to perpetrate cyberattacks
A typical office scanner can be infiltrated and a company's network compromised using different light sources, according to a new paper by researchers from Ben-Gurion University of the Negev and the Weizmann Institute of Science. "In the paper, "Oops! I Think I Scanned Malware," we demonstrated how to use a laser or smart bulb to establish a covert channel between an outside attacker and malware installed on a networked computer," says lead author Ben Nassi, a graduate student in the BGU Departm…

Facial recognition software helps diagnose rare genetic disease

Facial recognition software helps diagnose rare genetic disease
Researchers with the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, and their collaborators, have successfully used facial recognition software to diagnose a rare, genetic disease in Africans, Asians and Latin Americans. The disease, 22q11.2 deletion syndrome, also known as DiGeorge syndrome and velocardiofacial syndrome, affects from 1 in 3,000 to 1 in 6,000 children. Because the disease results in multiple defects throughout the body, including cle…

Parallel computation provides deeper insight into brain function

Parallel computation provides deeper insight into brain function
Unlike experimental neuroscientists who deal with real-life neurons, computational neuroscientists use model simulations to investigate how the brain functions. While many computational neuroscientists use simplified mathematical models of neurons, researchers in the Computational Neuroscience Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) develop software that models neurons to the detail of molecular interactions with the goal of eliciting new insights into …

An algorithm that knows when you'll get bored with your favorite mobile game

An algorithm that knows when you
The video game industry has been shaken up by the emergence of smartphone games, aimed at users who are constantly connected to the Internet and change games very frequently. África Periáñez -Head of Game Data Science at the video game company Silicon Studio, in Tokyo- and her team have developed a mathematical model that predicts when a user will leave a specific mobile game. The results of their work were presented at the International Conference on Data Science and Advanced Analytics, held la…

Humans, smartphones may fail frequently to detect face morph photos

Humans, smartphones may fail frequently to detect face morph photos
Researchers at the University of York have demonstrated that both humans and smartphones show a degree of error in distinguishing face morph photos from their 'real' faces on fraudulent identity cards. Previous study at the University has shown that it is difficult to match a pair of unfamiliar faces -- a photo of a person, against the real person -- presenting significant issues for authorities to spot identity fraud. Moving this research forward, the team investigated what the success rate wou…

Method speeds testing of new networking protocols

Method speeds testing of new networking protocols
The transmission control protocol, or TCP, which manages traffic on the Internet, was first proposed in 1974. Some version of TCP still regulates data transfer in most major data centers, the huge warehouses of servers maintained by popular websites. That's not because TCP is perfect or because computer scientists have had trouble coming up with possible alternatives; it's because those alternatives are too hard to test. The routers in data center networks have their traffic management protocols…

New software tool powers up genomic research

New software tool powers up genomic research
A group of computational biological researchers, led by Stony Brook University's Rob Patro, an Assistant Professor in the Department of Computer Science in the College of Engineering and Applied Sciences, has developed a new software tool, Salmon -- a lightweight method to provide fast and bias-aware quantification from RNA-sequencing reads. The research was published in the March 6 edition of Nature Methods. The team includes researchers from the Department of Computer Science at Stony Brook Un…

New brain-inspired cybersecurity system detects 'bad apples' 100 times faster

New brain-inspired cybersecurity system detects
Cybersecurity is critical -- for national security, corporations and private individuals. Sophisticated cybersecurity systems excel at finding "bad apples" in computer networks, but they lack the computing power to identify the threats directly. Instead, they look for general indicators of an attack; call them "apples." Or the system flags very specific patterns, such as "bad Granny Smith apples" or "bad Red Delicious apples." These limits make it easy for new species of "bad apples" to evade mo…

Using big data to analyze images, video better than the human brain

Using big data to analyze images, video better than the human brain
Improving traffic safety, better health services and environmental benefits -- Big Data experts see a wide range of possibilities for advanced image analysis and recognition technology. "Advanced image recognition by computers is the result of a great deal of very demanding work. You have to mimic the way the human brain distinguishes significant from unimportant information," says Eirik Thorsnes at Uni Research in Bergen, Norway. Thorsnes heads a group in the company's Centre for Big Data Analy…
