Misleading p-values showing up more often in biomedical journal articles

Tue, 03/15/2016 - 16:05
A review of p-values in the biomedical literature from 1990 to 2015 shows that these widely misunderstood statistics are being used increasingly, instead of better metrics of effect size or uncertainty.

Crowd review: Using the wisdom of the crowd to improve design

Tue, 03/15/2016 - 14:35
Research demonstrates how consumer product reviews published on the internet could be analyzed through data mining techniques and allow designers to find ways to improve a given product or even add features that had not occurred to the manufacturer.

Humanoid robot works in therapy for children with autism

Tue, 03/15/2016 - 01:15
Children with autism have special difficulty in expressing emotions, usually have no social skills and face major problems when communicating. In order to help children with this problem learn to recognize facial expressions in themselves and in others, a group of researchers created a robot using artificial intelligence.

Bacteria-powered microrobots navigate with help from new algorithm

Tue, 03/15/2016 - 01:14
Engineers have recently published research on a method for using electric fields to help tiny bio-robots propelled by flagellated bacteria navigate around obstacles in a fluid environment. These microrobots could one day be used for building microscopic devices or even delivering medication at the cellular level.

Light illuminates the way for bio-bots

Mon, 03/14/2016 - 20:12
A new class of miniature biological robots, or bio-bots, has seen the light -- and is following where the light shines. The bio-bots are powered by muscle cells that have been genetically engineered to respond to light, giving researchers control over the bots' motion, a key step toward their use in applications for health, sensing and the environment.

Experimentation and largest-ever quantum simulation of a disordered system explain quantum many-particle problem

Mon, 03/14/2016 - 19:16
Using some of the largest supercomputers available, physics researchers have produced one of the largest simulations ever to help explain one of physics most daunting problems.

Parent-infant learning programs need to be tailored for at-risk families

Mon, 03/14/2016 - 18:15
To more effectively and efficiently meet the needs of at-risk families, a study suggests the introduction of a technological enhancement to improve acquisition of skills developed during parent-infant sessions.

First prosthesis in the world with direct connection to bone, nerves and muscles

Mon, 03/14/2016 - 18:14
Thanks to the electrodes system a stable signal is obtained, which allows precise control like handling an egg without breaking. It also provides sensations as if it were a real hand.

What does your smartphone say when you tell it you were raped?

Mon, 03/14/2016 - 17:59
What does a smartphone say when you tell it you were raped, want to commit suicide, feel depressed or are being abused? More than 200 million adults in the United States own a smartphone and the majority use their phones to get health information, say authors of a new study.

Now researchers can follow the hectic life inside a cell

Mon, 03/14/2016 - 15:11
Living cells are constantly on the move. They move around and divide, and they are responsible for transporting molecules around inside themselves. Now researchers have developed a method that makes it possible to become a spectator at this hectic traffic. The method is of particular importance for disease research.

Robot learning companion offers custom-tailored tutoring

Mon, 03/14/2016 - 14:17
Scientists have developed a socially assistive robot called Tega designed to serve as a one-on-one peer learner in or outside of the classroom. Testing the setup in a Boston area preschool, the researchers showed Tega can learn and improve in response to the unique characteristics of students.

Could wearable technology give 'super powers' to humans?

Mon, 03/14/2016 - 13:13
More than just a fad, wearable technology (WT) can change the way we work and give us 'super powers', according to a new study.

DNA 'origami' could help build faster, cheaper computer chips

Mon, 03/14/2016 - 12:48
Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.

Social Networks Used in the Assessment of Damage Caused by Natural Disasters

Fri, 03/11/2016 - 19:17
It is possible to determine the damage caused by a natural disaster in just a few hours, by using data from social networks, such as Twitter, say researchers

Olin drone research aims to help fight wildfires

Fri, 03/11/2016 - 17:53
An American professor is working on proof of concept system to deploy drones into a wildfire and send back information in real time, potentially saving lives and livelihoods in the process.

New analytical model for e-sports predicts who is winning, and why

Fri, 03/11/2016 - 15:54
A new analytical model for e-sports not only helps game developers better understand how players perform, but can also predict the outcome of the game.

World's thinnest lens to revolutionize cameras

Fri, 03/11/2016 - 15:52
Scientists have created the world's thinnest lens, one two-thousandth the thickness of a human hair, opening the door to flexible computer displays and a revolution in miniature cameras. Researchers have said the discovery hinged on the remarkable potential of the molybdenum disulphide crystal.

Orchestration of systems of mobile robots for border protection, search and rescue, and personal security

Fri, 03/11/2016 - 13:46
New research enables the efficient planning of the activities of systems of mobile robots for socially beneficial services including border patrol, search and rescue, and security escort.

Android smartphone data spies exposed like bank robbers

Fri, 03/11/2016 - 13:41
When a bank is robbed, the loot will often contain a wad of manipulated banknotes. These will explode en route and release a colorful dye, marking the money as stolen. Researchers use a similar principle to identify spyware on smartphones. Computer scientists have now developed a matching application for the current version of the Android smartphone operating system, allowing for a more precise monitoring of malicious apps.

Using statistics to predict rogue waves

Fri, 03/11/2016 - 02:41
Scientists have developed a mathematical model to derive the probability of extreme waves. This model uses multi-point statistics, the joint statistics of multiple points in time or space, to predict how likely extreme waves are. The results demonstrate that evolution of these probabilities obey a well-known function, greatly reducing the complexity of the results.
