A row-bot that loves dirty water

Tue, 11/24/2015 - 01:28
Taking inspiration from water beetles and other swimming insects, academics have developed the Row-bot, a robot that thrives in dirty water. The Row-bot mimics the way that the water boatman moves and the way that it feeds on rich organic matter in the dirty water it swims in.

New supercomputer simulations enhance understanding of protein motion, function

Tue, 11/24/2015 - 01:23
Supercomputing simulations could change how researchers understand the internal motions of proteins that play functional, structural and regulatory roles in all living organisms, say scientists in a new report.

Words can deceive, but tone of voice cannot

Tue, 11/24/2015 - 01:23
An analysis of the tone of voice used by couples during therapy allowed a computer algorithm to predict whether a relationship would improve. In fact, the algorithm did a better job of predicting marital success of couples with serious marital issues than descriptions of the therapy sessions provided by relationship experts.

Computers can perceive image curves like artists

Mon, 11/23/2015 - 15:34
Imagine computers being able to understand paintings or paint abstract images much like humans. Now a researcher demonstrates a breakthrough concept in the field of computer vision using curves and lines to represent image shapes and furthermore to recognize objects.

Brains behind the wheel: Could virtual reality teach us to avoid real life accidents

Mon, 11/23/2015 - 15:33
Using their state-of-the-art simulation facility, scientists are exploring the use of car driving simulators as tools for training and testing drivers in order to reduce road traffic accidents and fatalities.

Show me how you write on social media and I'll tell you your age and sex

Mon, 11/23/2015 - 15:30
A new tool can detect the sex and age range of the authors behind posts and other comments on social networks. Potential applications include its use in delinquent profiling and detection of pedophile cases. It is also a valuable tool for companies, offering a window onto their customer base and informing more focused marketing actions.

Forecasting the path of breast cancer in a patient

Mon, 11/23/2015 - 15:18
A mathematical model has been developed to forecast metastatic breast cancer survival rates using techniques usually reserved for weather prediction, financial forecasting and surfing the Web.

Tiny robots inspired by pine cones

Sun, 11/22/2015 - 18:31
The future of bio-inspired engineering or robotics will greatly benefit from lessons learned from plants, according to a group of researchers. They will share details about how studying plants enabled them to create tiny robots powered exclusively by changes in humidity.

Strange quantum phenomenon achieved at room temperature in semiconductor wafers

Fri, 11/20/2015 - 23:26
Researchers have demonstrated that macroscopic entanglement can be generated at room temperature and in a small magnetic field.

Electronic plants created

Fri, 11/20/2015 - 23:26
Researchers have created analog and digital electronics circuits inside living plants. The scientists have used the vascular system of living roses to build key components of electronic circuits.

Quantum simulation: A better understanding of magnetism

Fri, 11/20/2015 - 15:40
Physicists have used ultracold atoms to imitate the behavior of electrons in a solid. Researchers have devised a new way to study the phenomenon of magnetism. Using ultracold atoms at near absolute zero, they prepared a model that simulates the behavior of electrons in a solid, which enables the investigation of magnetic properties.

Fri, 11/20/2015 - 14:41
Scientists have discovered new evidence to support the development of scalable and secure high rate quantum networks.

First-in-human use of virtual reality imaging in cardiac cath lab to treat blocked coronary artery

Fri, 11/20/2015 - 14:21
Virtual reality has potential to revolutionize some aspects of medicine and healthcare. Several medical specialties are already using it to train physicians and assist diagnosis and it also has potential for treatment. A group of cardiologists has now successfully used a VR device to guide the opening up (revascularization) of a chronically blocked right coronary artery.

Email security improving, but far from perfect

Thu, 11/19/2015 - 16:35
Email security helps protect some of our most sensitive data: password recovery confirmations, financial data, confidential correspondences, and more. According to a new report, email security is significantly better than it was two years ago, but still has widespread issues.

Preventing famine with mobile phones

Thu, 11/19/2015 - 15:33
With a mobile data collection app and satellite data, scientists will be able to predict whether a certain region is vulnerable to food shortages and malnutrition, say experts. By scanning Earth's surface with microwave beams, researchers can measure the water content in soil. Comparing these measurements with extensive data sets obtained over the last few decades, it is possible to calculate whether the soil is sufficiently moist or whether there is danger of droughts. The method has now been tested in the Central African Republic.

Testing new magnetic semiconductor material

Wed, 11/18/2015 - 21:05
A novel magnetic semiconductor material that is an alloy of cobalt, iron, chromium and aluminum in which part of the aluminum was replaced with silicon may help reduce the power needed to store data in the computer memory.
