Machine learning writes songs that elicits emotions from its listeners

Thu, 03/09/2017 - 17:06
Music, more than any art, is a beautiful mix of science and emotion. It follows a set of patterns almost mathematically to extract feelings from its audience. Machines that make music focus on these patterns, but give little consideration to the emotional response of their audience. Scientists have developed a new machine-learning device that detects the emotional state of its listeners to produce new songs that elicit new feelings.

Single atom memory: The world's smallest storage medium

Thu, 03/09/2017 - 17:05
One bit of digital information can now be successfully stored in an individual atom. This result is a breakthrough in the miniaturization of storage media and has the potential to serve as a basis for quantum computing.

The prototype of a chemical computer detects a sphere

Thu, 03/09/2017 - 17:05
Chemical computers are becoming ever more of a reality. It turns out that after an appropriate teaching procedure even a relatively simple chemical system can perform non-trivial operations. In their most recent computer simulations researchers have shown that correctly programmed chemical matrices of oscillating droplets can recognize the shape of a sphere with great accuracy.

Telemedicine ambulance may deliver faster stroke care

Wed, 03/08/2017 - 21:21
When experiencing a stroke, people who are brought to the hospital in an ambulance with a CT scanner and telemedicine capabilities are evaluated and treated nearly two times faster than people taken in a regular ambulance, according to a study.

Studying altruism through virtual reality

Wed, 03/08/2017 - 18:13
A computer-based environment has been developed with the aim to shed light on the origins of altruism. This new study immersed participants in a virtual environment that reproduced a building on fire which they had to evacuate in a hurry, deciding whether to save their lives or interrupt their escape and help rescue an injured person. The results showed that altruistic individuals self-reported to have greater concern for others’ wellbeing and had larger right anterior insula (a brain area involved in processing social emotions) compared to non-altruists.

Computer linguists are developing an intelligent system aid for air traffic controllers

Wed, 03/08/2017 - 16:48
Human lives depend on their decisions, and psychological stress levels are high. An average radio contact takes 3.5 to 11.3 seconds, during which the air traffic controller checks in with the pilot, examines the radar screens and gives out new instructions. The current technical support systems typically lack the ability to understand and process these brief radio exchanges.

Artificial intelligence virtual consultant helps deliver better patient care

Wed, 03/08/2017 - 16:48
Interventional radiologists are using technology found in self-driving cars to power a machine learning application that helps guide patients' interventional radiology care.

Technique proposed for measuring weak or nonexistent magnetic fields

Wed, 03/08/2017 - 16:47
Researchers have proposed a new approach to sampling materials with weak or no magnetic fields. The method could help advance research in a host of fields, from computing to MRI machines.

The sky is the limit for new low-cost 3D printer

Wed, 03/08/2017 - 13:37
A research team is in the process of making a 3D printed Tower of Babel using a novel hanging printer. This offers a low-cost solution and increased flexibility to print large volumes.

Violent video games found not to affect empathy

Wed, 03/08/2017 - 13:10
The link between playing violent video games and antisocial behavior, such as increased aggression and decreased empathy, is hotly debated. In a recent study the long-term effects of playing violent video games were investigated. This study found that empathy is not blunted by playing such games long-term.

Equation helps to explain plant growth

Tue, 03/07/2017 - 19:27
A new biology breakthrough has important implications for plants as they adapt to a warming environment, say authors of a new report.

Hiring data creates risk of workplace bias

Tue, 03/07/2017 - 19:18
American employers increasingly rely on large datasets and computer algorithms to decide who gets interviewed, hired or promoted. While these data algorithms can help to avoid biased human decision-making, they also risk introducing new forms of bias or reinforcing existing biases, suggests a new report.

Computer models could allow researchers to better understand, predict adverse drug reactions

Tue, 03/07/2017 - 16:45
Computer model shows what happens at the molecular level during severe allergic reactions to abacavir, a common HIV drug

Manufacturing method may help keep work in high-cost areas

Tue, 03/07/2017 - 16:29
A new study describes seru as a cellular assembly approach. The system appears to offer promise for manufacturing in dynamic, high-cost markets.

Understanding the motion of vortex domain walls in ferromagnetic nanowires

Tue, 03/07/2017 - 16:29
Almost all information that exists in contemporary society is recorded in magnetic media, like hard drive disks. Researchers are studying the motion of vortex domain walls -- local regions of charge that collectively store information via their configuration -- driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y-like branch.

Computer simulations first step toward designing more efficient amine chemical scrubbers

Tue, 03/07/2017 - 16:29
A proof-of-concept molecular modeling study that analyzes the efficiency of amine solutions in capturing carbon dioxide is the first step toward the design of cheaper, more efficient amine chemicals for capturing carbon dioxide -- and reducing harmful CO2 emissions -- in industrial installations.

Cyberbullying rarely occurs in isolation, research finds

Tue, 03/07/2017 - 14:05
Cyberbullying doesn’t create large numbers of new victims, say researchers. Most bullying is face-to-face – with cyberbullying used as a modern tool to supplement traditional forms. A new study has found that 29% of UK teenagers reported being bullied, but only 1% were victims of cyberbullying alone. Therefore, say authors of a new report, bullying intervention strategies should focus on traditional bullying as well as cyberbullying.

Robot uses social feedback to fetch objects intelligently

Mon, 03/06/2017 - 20:17
By enabling them to ask a question when they're confused, an algorithm helps robots get better at fetching objects, an important task for future robot assistants.

Tree growth model assists breeding for more wood

Mon, 03/06/2017 - 19:46
A meeting in a forest between a biologist and a mathematician could lead to thicker, faster growing trees.

Computational method makes gene expression analyses more accurate

Mon, 03/06/2017 - 16:42
A new computational method can improve the accuracy of gene expression analyses, which are increasingly used to diagnose and monitor cancers and are a major tool for basic biological research. Researchers report that their method is able to correct for the technical biases that are known to occur during RNA sequencing, the leading method for estimating gene expression.
