The power of mathematics to open new possibilities in music has been demonstrated by scientists for years. Modern experiments with computer music are just the most recent example.
The best way to combat cyberattacks may be a joint public-private partnership between government and business, says a new paper. Cybersecurity is a big deal, and the protection of critical network infrastructure is a matter of national security," said one expert. "If nothing else, cyberattacks are very expensive, costing the global economy almost a half-trillion dollars per year, according to some estimates. For either of those reasons alone it should be given more attention."
The keyword term a consumer uses in their search engine query can predict the likelihood that they will click on an organic or paid advertisement. That's according to new research that takes a unique look at a consumer's behavior between the keyword search and the point-of-click. The new information may give marketers the edge in converting even more consumer clicks on their sites.
Most people know children learn many skills simply by watching people around them. Without explicit instructions youngsters know to do things like press a button to operate the television and twist a knob to open a door. Now researchers have taken this further, finding that children as young as age 2 intuitively use mathematical concepts such as probability to help make sense of the world around them.
With approximately 50 million scientific papers available in public databases -- and a new one publishing nearly every 30 seconds -- scientists cannot know about every relevant study when they are deciding where to take their research next. A new tool in development by computational biologists and analytics experts tested as a 'proof-of-principle' may one day help researchers mine all public medical literature and formulate hypotheses that promise the greatest reward when pursuing new scientific studies.
Engineers have successfully piloted the world's first ZigBee-based inter-satellite communication system. Designed to evaluate the performance of wireless sensor networks (WSNs) in space, the experiment marks a breakthrough in aeronautical engineering.
A physics model helps scientists accurately predict the likely outcome of a chemical reaction as well as sheds new light on mysterious quantum states, including the Efimov effect.
Robo Brain -- a large-scale computational system that learns from publicly available Internet resources -- is currently downloading and processing about 1 billion images, 120,000 YouTube videos, and 100 million how-to documents and appliance manuals. The information is being translated and stored in a robot-friendly format that robots will be able to draw on when they need it.
A new statistical genetic analysis can detect when lymphoma will be aggressive, researchers report, thereby, allowing treatment to be initiated in time. The statistical method will be able to determine who will need a bone-marrow transplantation and who can be spared the extreme burden that this excruciating treatment entails.
During plant growth, dividing cells in meristems must coordinate transitions from division to expansion and differentiation. Three distinct developmental zones are generated, while at the same time, plants can rapidly adjust their direction of growth to adapt to environmental conditions. Now researchers have found out, with the help of experimentation and mathematical modelling, how many factors together regulate root growth.
Scientists can now monitor and record the activity of hundreds of neurons concurrently in the brain, and ongoing technology developments promise to increase this number. However, simply recording the neural activity does not automatically lead to a clearer understanding of how the brain works. In a new article, researchers describe the scientific motivations for studying the activity of many neurons together, along with a class of machine learning algorithms for interpreting the activity.
Cancer subtypes are like rare diseases; a new kind of clinical trial uses Dr. Google to find enough needles in enough haystacks to test drug ponatinib against FGFR positive lung cancer.
Are young people losing the ability to read emotions in our digital world? Scientists report that sixth-graders who went five days without even glancing at a smartphone, television or other screen did substantially better at reading emotions than sixth-graders from the same school who, as usual, spent hours each day looking at their smartphones and other screens.
For many people, finding motivation to exercise is a challenge. Thankfully, there are Zombies chasing you. At least that's the approach of Zombies, Run! -- one of more than 31,000 health and fitness apps on the market today, and one of the growing number of apps that use games to increase physical activity. Gamification is currently the popular trend for mobile fitness apps, but whether or not it's the best way to exercise remains to be seen.
Targeted automated alerts in electronic health records significantly reduce urinary tract infections in hospital patients with urinary catheters. In addition, when the design of the alert was simplified, the rate of improvement dramatically increased.
Using telecommunications to connect stroke experts to stroke patients in rural areas continued to improve and sustain stroke care, according to new research. With the tele-medical linked Stroke Units, patients in regional hospitals had around-the-clock access to consultations with vascular neurologists at stroke centers, including evaluation of brain imaging and patient examination via videoconferencing when needed.
A novel “man and machine” decision support system for diagnosing malaria infection has been developed by researchers. This innovative diagnostic aid is based on computer vision algorithms similar to those used in facial recognition systems combined with visualization of only the diagnostically most relevant areas. Tablet computers can be utilized in viewing the images.
Computer scientists have identified a weakness believed to exist in Android, Windows and iOS mobile operating systems that could be used to obtain personal information from unsuspecting users. They demonstrated the hack in an Android phone.
In the near future, the package that you ordered online may be deposited at your doorstep by a drone: Last December, online retailer Amazon announced plans to explore drone-based delivery, suggesting that fleets of flying robots might serve as autonomous messengers that shuttle packages to customers within 30 minutes of an order. A new algorithm lets drones monitor their own health during long package-delivery missions.
New research outlines the possible coping mechanisms that might be needed following loss or theft of one's smart phone or other digital devices and the security problems that the user might face.
