PolyU has developed a novel computer-aided detection system for acute stroke using computer intelligence technology. Reading 80 to 100 computer images, the system is able to detect whether the patient was struck by ischemic stroke or haemorrhagic stroke. The detection accuracy is 90 percent, which is as high as that conducted by specialists, but at a much reduced time from 10 to 15 minutes to just three minutes.
Evolutionary biologists and computer scientists have come together study the evolution of pop music. Their analysis of 17,000 songs from the US Billboard Hot 100 charts, 1960 to 2010, is the most substantial scientific study of the history of popular music to date. They studied trends in style, the diversity of the charts, and the timing of musical revolutions.
Computer simulation of the body’s inflammatory response to traumatic injury accurately replicated known individual outcomes and predicted population results. Researchers examined blood samples from 33 survivors of car or motorcycle accidents or falls for multiple markers of inflammation, including interleukin-6, and segregated the patients into categories of trauma severity. They were able to validate model predictions.
When ants go exploring in search of food they end up choosing collective routes that fit statistical distributions of probability. This has been demonstrated by a team of mathematicians after analyzing the trails of a species of Argentine ant. Studies like this could be applied to coordinate the movement of micro-robots in cleaning contaminated areas for example.
In what marks a significant step forward for artificial intelligence, researchers at UC Santa Barbara have demonstrated the functionality of a simple artificial neural circuit. For the first time, a circuit of about 100 artificial synapses was proved to perform a simple version of a typical human task: image classification.
Using a smart tablet and a red beam of light, researchers have created a system that allows people to control a fleet of robots with the swipe of a finger. A person taps the tablet to control where the beam of light appears on a floor. The swarm robots then roll toward the illumination, constantly communicating with each other and deciding how to evenly cover the lit area.
The list of authors for an article on comparative genomics of a fruit fly chromosome runs three single-spaced pages. Large author lists are the norm in high-energy physics, but a novelty in biology. What is going on? The 1,014 authors include 940 undergraduates from 63 institutions, all working in parallel to solve mysteries embedded in the DNA sequences of the unusual dot chromosome in fruit flies. A large collaboration is providing...
Protecting the world from destruction by asteroids sounds like superhuman power, but NASA scientists work tirelessly to ensure that humans today are protected from this potential harm. Asteroids need to be hunted in order to identify which ones may endanger Earth, and analyzing the big data puzzle of asteroid detection has been an arduous process. That is, until the power of crowdsourcing was discovered.
Overturning cars, flying missiles and airplanes speeding across the screen — on modern computers, 3-D objects can be calculated in a flash. However, many surfaces still look unnatural. Whether it is skin, stone or wax — on the computer screen, all materials look alike, as if the objects had all been cut out of the same opaque material. A new mathematical method takes into account light scattering that occurs below the surface...
Self-driving cars. Computers that detect tumors. Real-time speech translation. Just a few years ago, deep learning — training computers to identify patterns and objects, much like the way humans do — was the domain of a few artificial intelligence and data science researchers. No longer. Today, top experts use it to do amazing things. And they continue to push the bounds of what’s possible.
Computer scientists at the University of California, San Diego, have combined sophisticated computer vision algorithms and a brain-computer interface to find mines in sonar images of the ocean floor. The study shows that the new method speeds detection considerably, when compared to existing methods — mainly visual inspection by a mine detection expert.
Even non-professionals may someday be able to create high-quality video panoramas using multiple cameras with the help of an algorithm developed by a team of Disney researchers. Their method smooths out the blurring, ghosting and other distortions that routinely occur when video feeds from unstructured camera arrays are combined to create a single panoramic video.
A research team has demonstrated a predictive modeling capability that can help accelerate the discovery of new materials to improve biofuel and petroleum production. The findings present a tool that could lead to more efficient processes in the biofuel and petrochemical industries, while reducing the time and cost of associated laboratory research and development efforts. The materials of interest are called zeolites.

If you find yourself sweating out a day that is monstrously hot, chances are you can blame humanity. A new report links three out of four such days to man's effects on climate. And as climate change worsens around mid-century, that percentage of extremely hot days being caused by man-made greenhouse gases will push past 95 percent.
At first glance, there is not the slightest doubt: to us, the universe looks three-dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle” asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as 3-D may just be the image of 2-D processes on a huge cosmic horizon.
A new technique of visualizing the complicated relationships between anything from Facebook users to proteins in a cell provides a simpler and cheaper method of making sense of large volumes of data.
Curtis writes algorithms that enable computers to solve large-scale continuous optimization problems. He is collaborating with researchers at Argonne through a five-year Early Career Award from the U.S. Department of Energy. In a three-year single-investigator project for the NSF, Curtis has developed algorithms that solve large-scale continuous optimization problems in less than a quarter of the time required by conventional methods.
The next generation of cyberattacks will be more sophisticated, more difficult to detect and more capable of wreaking untold damage on the nation’s computer systems. So, the DoD has given a $3 million grant to a team of computer scientists to develop software that can hunt down a new kind of vulnerability nearly impossible to find with today’s technology. The team is tasked with creating an analyzer that can thwart algorithmic attacks.
Simply declaring a region as a nature protection area is not enough, regular monitoring of its ecological condition is also necessary. New methods are being developed to monitor Europe’s nature protection areas from the air. Short laser pulses are sent to the ground, and information on the status of the habitat can be deduced from the reflected light signals using elaborate computer algorithms.
A key handwritten scientific document by Alan Turing in which he works on the foundations of mathematical notation and computer science was sold for $1,025,000 in the Fine Books & Manuscripts Sale at Bonhams New York.
Notorious gangsters Al Capone and Carlo Gambino were famously done in by tax evasion charges. John Gotti, the “Teflon Don” was given up by a confidant. While the criminal masterminds of today are conducting their nefarious business online, the key to taking them down depends on understanding how they organize and where to squeeze them. Researchers are searching for that pressure point by studying the activity of cybercrime forums.
As part of the 2015 Cambridge Science Festival, David Spiegelhalter, Winton Professor for the Understanding of of Risk at Cambridge University, has given an overview of the history of sex research using data going back to 1580, conducted by pioneering sexologists through to today’s ‘sexperts.’
A young doctor leans over a patient who has been in a serious car accident and invariably must be experiencing pain. The doctor's trauma team examines the patient's pelvis and rolls her onto her side to check her spine. They scan the patient's abdomen with a rapid ultrasound machine, finding fluid. They insert a tube in her nose. Throughout the procedure, the patient's face remains rigid, showing no signs of pain.
Researchers are designing artificial limbs to be more sensational, with the emphasis on sensation. They have developed a language of touch that can be "felt" by computers and humans alike. The engineers and students are constructing a language quantified with mechanical touch sensors that interact with objects of various shapes, sizes and textures.
