Construction of practical quantum computers radically simplified

Fri, 12/02/2016 - 15:34
Scientists have invented a ground-breaking new method that puts the construction of large-scale quantum computers within reach of current technology.

New evidence on the formation of the solar system

Fri, 12/02/2016 - 15:10
Scientists are using new computer models and evidence from meteorites to show that a low-mass supernova triggered the formation of our solar system.

Phantom movements in augmented reality helps patients with chronic intractable phantom limb pain

Fri, 12/02/2016 - 02:22
A novel method of treating phantom limb pain has been developed using machine learning and augmented reality. This approach has been tested on over a dozen of amputees with chronic phantom limb pain who found no relief by other clinically available methods before. The new treatment reduced their pain by approximately 50 per cent, reports a clinical study.

Climate change will drive stronger, smaller storms in U.S., new modeling approach forecasts

Thu, 12/01/2016 - 22:23
The effects of climate change will likely cause smaller but stronger storms in the United States, according to a new framework for modeling storm behavior. Though storm intensity is expected to increase over today’s levels, the predicted reduction in storm size may alleviate some fears of widespread severe flooding in the future.

What do Netflix, Google and planetary systems have in common?

Thu, 12/01/2016 - 21:55
Machine learning is a powerful tool used for a variety of tasks in modern life, from fraud detection and sorting spam in Google, to making movie recommendations on Netflix. Now a team of researchers has developed a novel approach in using it to determine whether planetary systems are stable or not.

New algorithm could explain human face recognition

Thu, 12/01/2016 - 21:53
Researchers have developed a new computational model of the human brain's face-recognition mechanism that seems to capture aspects of human neurology that previous models have missed.

A friend of a friend is…a dense network

Thu, 12/01/2016 - 21:36
Networks evolve in different ways depending how often "second neighbor," or friends of friends, connections occur.

New computational method to create drugs more efficiently

Thu, 12/01/2016 - 21:08
Researchers have developed a more efficient computational method to identify new drugs. The study proposes a new way of facing the discovery of molecules with biological activity.

Computer learns to recognize sounds by watching video

Thu, 12/01/2016 - 17:10
In recent years, computers have gotten remarkably good at recognizing speech and images: Think of the dictation software on most cellphones, or the algorithms that automatically identify people in photos posted to Facebook. But recognition of natural sounds has lagged behind. That's because most automated recognition systems, whether they process audio or visual information, are the result of machine learning, in which computers search for patterns in huge compendia of training data, say investigators.

Geographers provide new insight into commuter megaregions of the US

Thu, 12/01/2016 - 16:58
Geographers provide new insight into the economic geography of commuter megaregions in the U.S., by using an empirical approach that combines visual interpretation with statistical analysis. The findings shed light on an old geographic problem: how to divide space into coherent unit areas.

Making graphene using laser-induced phase separation

Thu, 12/01/2016 - 16:46
All our smart phones have shiny flat AMOLED displays. Behind each single pixel of these displays hide at least two silicon transistors which were mass-manufactured using laser annealing technologies. While the traditional methods to make them uses temperatures above 1,000°C, the laser technique reaches the same results at low temperatures even on plastic substrates (melting temperature below 300°C). Interestingly, a similar procedure can be used to generate crystals of graphene.

Narcissistic individuals use social media to self-promote

Thu, 12/01/2016 - 16:27
Narcissism has a modest but reliable positive relationship with a range of social media behaviors, a new statistical review of 62 studies with over 13,000 individuals found.

Suggestions for you: A better, faster recommendation algorithm

Thu, 12/01/2016 - 15:17
The internet is rife with recommendation systems, suggesting movies you should watch or people you should date. These systems are tuned to match people with items, based on the assumption that similar people buy similar things and have similar preferences. In other words, an algorithm predicts which items you will like based only on your, and the item's, previous ratings. Now researchers have unveiled a more accurate, efficient algorithm for internet recommendations.

Artificial intelligence toolkit spots new child sexual abuse media online

Thu, 12/01/2016 - 14:30
New artificial intelligence software designed to spot new child sexual abuse media online could help police catch child abusers. The toolkit automatically detects new child sexual abuse photos and videos in online peer-to-peer networks.

Researchers take first look into the 'eye' of majoranas

Thu, 12/01/2016 - 14:27
Majorana fermions are particles that could potentially be used as information units for a quantum computer. An experiment has confirmed their theory that Majorana fermions can be generated and measured on a superconductor at the end of wires made from single iron atoms. The researchers also succeeded in observing the wave properties of Majoranas and, therefore, in making the interior of a Majorana visible for the first time.

Economists examined US legal cannabis sector to gauge value of banking services

Thu, 12/01/2016 - 14:26
Despite the many innovative services in the digital age, conventional banking remains important to newly-established businesses; banking cannot yet be replaced by online financial services such as crowdfunding or PayPal, according to a recent study. The economic researchers investigated what role the traditional banks play for newly-founded companies within a highly-developed economy based on the unique example of the US cannabis industry. They found that both the credit and transaction services traditionally provided by banks are key.

Online insomnia program can improve sleep for many, study finds

Wed, 11/30/2016 - 19:13
An online program designed to help people overcome insomnia significantly improves both the amount and quality of sleep, a new study has found. The study is the first to look closely at the effects of the Sleep Healthy Using the Internet (SHUTi) program on people with health conditions that could be affecting their sleep.

What makes Bach sound like Bach? New dataset teaches algorithms classical music

Wed, 11/30/2016 - 19:10
MusicNet is the first publicly available large-scale classical music dataset designed to allow machine learning algorithms to tackle a wide range of open challenges -- from automated music transcription to listening recommendations based on the structure of music itself.
