A computer science professor reveals how to print a 3-D Christmas tree efficiently and with zero material waste, using the world's first algorithm for automatically decomposing a 3-D object into what are called pyramidal parts.

Searching for new ways to develop efficient, flexible networks, physicists discovered the designs of spider webs and leaf venation, refined across thousands of years of evolution, are worthy models for the next generation of optoelectronic applications.

For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects, which the human brain does very accurately and quickly. Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. Now neuroscientists have found that one of the latest generation of 'deep neural networks' matches the primate brain.

Science and Information / Algorithm the right route to disaster relief
« on: December 30, 2014, 03:09:47 PM »
A new mapping tool makes preparing for natural disasters and responding to their aftermath easier than ever. Researchers have developed a computer model that analyzes networks of interconnected roads to predict the speediest routes for rescuers to take using real-time data uploaded by aid workers on the ground.

If data could be encoded without current, it would require much less energy and make things like low-power, instant-on computing a ubiquitous reality. Scientists have made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field.

Science and Information / Breakthrough in optical fiber communications
« on: December 30, 2014, 03:05:32 PM »
Researchers from the University of Southampton have revealed a breakthrough in optical fiber communications. They developed an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals. The research explores a radically new approach to the generation of spectrally-efficient advanced modulation format signals as required in modern optical communication systems.

Despite showing interest in web or mobile apps to help manage their type 2 diabetes, only a small number of older adults actually use them, says a new study. Approximately 2.2 million Canadians are living with type 2 diabetes, 2 million of whom are age 50 or older. A study found that although more than 90 per cent of research participants owned a computer or had daily Internet access, just 18 per cent used applications on this technology to help manage their diabetes. While almost half owned smartphones, only 5 per cent used them to manage their disease.

Cheaper 3-D virtual reality system: Powerful enough for a gamer, made for an engineer

It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3-D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming. On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3-D glasses worn by the user create dizzying added dimensions.

Science and Information / Atom-thick CCD could capture images
« on: December 30, 2014, 03:01:32 PM »
An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.

Online giants including Amazon and LinkedIn could be doing far more to raise awareness of the need for better password practices among their users, a study has found. The research revealed that very few of them give detailed guidance about the importance of providing secure passwords, either when users were creating or updating accounts.

Science and Information / Decision 'cascades' in social networks
« on: December 30, 2014, 02:58:23 PM »
People in social networks are often influenced by each other's decisions, resulting in a run of behaviors in which their choices become highly correlated, causing a cascade of decisions.

Researchers are closer to creating underwater robotic creatures with a brain of their own -- besides behaving like the real thing. In the near future, it would not be too tall an order for the team to produce a swarm of autonomous tiny robotic sea turtles and fishes for example, to perform hazardous missions such as detecting nuclear wastes underwater or other tasks too dangerous for humans.

A fast-paced game app where players pretend they are baggage screening officers operating airport x-ray scanners has provided researchers with billions of pieces of data in record time, according to an article. "Mobile devices offer researchers an exciting new means to crowdsource an experiment using games that are actually tests of cognition or other brain functions," said the lead author of the report. "Questions that could have taken decades to answer in a laboratory setting, or that could not be realistically answered in a lab, can be examined using big data gathered in a relatively short time."

People with fewer friends on Facebook raise more money for charity than those with lots of connections, research by an economist has found. "Giving behavior is largely affected by existing personal relationships, whether its friends, family or work colleagues -- these factors are extremely important according to the responses we had from donors," says the author.
