Academics earn street cred with TED Talks but no points from peers

Tue, 06/18/2013 - 18:14
TED Talks, the most popular conference and events website in the world with over 1 billion informational videos viewed, provides academics with increased popular exposure but does nothing to boost citations of their work by peers, new research has found.

Tiny batteries: 3-D printing could lead to miniaturized medical implants, compact electronics, tiny robots

Tue, 06/18/2013 - 18:14
Three-dimensional printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.

Fiber-optic pen helps see inside brains of children with learning disabilities

Tue, 06/18/2013 - 17:18
For less than $100, researchers have designed a computer-interfaced drawing pad that helps scientists see inside the brains of children with learning disabilities while they read and write.

Working backward: Computer-aided design of zeolite templates

Tue, 06/18/2013 - 14:20
Taking a page from computer-aided drug designers, researchers have developed a computational method that chemists can use to tailor the properties of zeolites, one of the world's most-used industrial minerals. The method allows chemists to work backward by first considering the type of zeolite they wish to make and then creating the organic template needed to produce it.

Which qubit my dear? New method to distinguish between neighboring quantum bits

Tue, 06/18/2013 - 14:17
Researchers have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer. In a significant feat of atomic engineering, they were also able to read-out the spins of individual electrons on a cluster of phosphorus atoms that had been placed precisely in silicon.

Four microphones and a computer algorithm are enough to produce a 3-D model of a simple, convex room

Mon, 06/17/2013 - 20:08
An algorithm makes it possible to measure the dimensions of a room using just a few microphones and a snap of your fingers. There are many promising applications on the horizon.

NASA tests radio for unmanned aircraft operations

Mon, 06/17/2013 - 17:08
NASA's communications experts have begun flight testing a prototype radio as part of the agency's contributions toward fully integrating civil and commercial Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS). This particular radio is one of the first steps to provide the critical communications link for UAS pilots on the ground to safely and securely operate their remotely piloted vehicles in flight even though they are many miles -- if not continents or oceans -- apart.

Is there an invisible tug-of-war behind bad hearts and power outages?

Mon, 06/17/2013 - 16:24
Researchers report the first purely physical experimental evidence that an invisible and chaotic tug-of-war known as a chimera state can occur naturally within any process that relies on spontaneous synchronization, including clock pendulums, power grids and heart valves.

Artificial bone: Designing synthetic materials and quickly turning the design into reality with 3-D printing

Mon, 06/17/2013 - 16:23
Researchers have developed a new method to design synthetic materials and quickly turn the design into reality using computer optimization and 3-D printing.

Cheetah-cub: A robot that runs like a cat

Mon, 06/17/2013 - 14:46
Thanks to its legs, whose design faithfully reproduces feline morphology, a four-legged "cheetah-cub robot" has the same advantages as its model: it is small, light and fast. Still in its experimental stage, the robot will serve as a platform for research in locomotion and biomechanics.

Intelligent glasses designed for professors

Mon, 06/17/2013 - 14:45
Scientists in Spain have developed a system based on augmented reality that, thanks to intelligent glasses, enables a professor to see notes or comments on the contents of a lesson and to see if the students understand explanations or if, on the contrary, they are having doubts or difficulties.

Researchers unmask Janus-faced nature of mechanical forces with supercomputer

Mon, 06/17/2013 - 13:19
The harder you pull, the quicker it goes. At least, that used to be the rule in mechanochemistry, a method that researchers apply to set chemical reactions in motion by means of mechanical forces. However, as chemists report in a new study, more force cannot in fact be translated one to one into a faster reaction. With complex molecular dynamic simulations on a supercomputer, they unmasked the Janus-faced nature of mechanochemistry. Up to a certain force, the reaction rate increases in proportion to the force. If this threshold is exceeded, greater mechanical forces speed up the reaction to a much lesser extent.

Automated 'coach' could help with social interactions

Fri, 06/14/2013 - 16:56
A new software system could help people improve their conversational and interview skills.

Predicting collective online behavior

Fri, 06/14/2013 - 14:07
Scientists are evaluating the impact of a website based on the interaction between its users with the entire Web.

Detecting homemade explosives, not toothpaste

Fri, 06/14/2013 - 14:07
Researchers want airports, border checkpoints and others to detect homemade explosives made with hydrogen peroxide without nabbing people whose toothpaste happens to contain peroxide.

Using math to kill cancer cells

Fri, 06/14/2013 - 12:26
Scientists have outlined how advanced mathematical modelling can be used in the fight against cancer. The technique predicts how different treatments and genetic modifications might allow cancer-killing, oncolytic viruses to overcome the natural defences that cancer cells use to stave off viral infection.

Can you feel me now? New array measures vibrations across skin, may help engineers design tactile displays

A new array measures vibrations across skin may help engineers design tactile displays.

Greater convenience and safety for wheelchair users

Thu, 06/13/2013 - 15:20
With modern communication aids, users of electric powered wheelchairs can operate a PC and cellphone without human assistance. A new module is set to transform electric powered wheelchairs into communication hubs.

World population could be nearly 11 billion by 2100

Thu, 06/13/2013 - 15:19
A new United Nations analysis shows the world population could reach nearly 11 billion by the end of the century, about 800 million more people than the previous projection issued in 2011.

Repairing turbines with the help of robots

Thu, 06/13/2013 - 14:41
Compressor and turbine blades are important components in aircraft engines and gas turbines. When they become damaged, it is often cheaper to repair them than to buy replacements. Now there is a new robotassisted technique that is boosting efficiency.
