A micro-muscular breakthrough: Powerful new microscale torsional muscle/motor from vanadium dioxide

Posted: 19 Dec 2013 05:01 PM PST

Researchers have demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length faster than the blink of an eye.

Graphene-based field-effect transistor with semiconducting nature opens up practical use in electronics

Posted: 19 Dec 2013 12:44 PM PST

Scientists have announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field-effect transistor (FET) with semiconducting nature. This opens up opportunities for practical use in electronic devices.

Graphene sees the light: Sheets of carbon just one atom thick could be used in photovoltaic cells

Posted: 19 Dec 2013 12:44 PM PST

Sheets of carbon just one atom thick could make effective transparent electrodes in certain types of photovoltaic cells.

Catching the big wave: 'Universal ripple' could hold the secret to high-temperature superconductivity

Posted: 19 Dec 2013 11:23 AM PST

Researchers have discovered a universal electronic state that controls the behavior of high-temperature superconducting copper-oxide ceramics.

Electron 'antenna' tunes in to physics beyond Higgs

Posted: 19 Dec 2013 11:23 AM PST

In making the most precise measurements ever of the shape of electrons, a team of Harvard and Yale scientists have raised severe doubts about several popular theories of what lies beyond the Higgs boson.

New salt compounds challenge the foundation of chemistry

Posted: 19 Dec 2013 11:21 AM PST

All good research breaks new ground, but rarely does the research unearth truths that challenge the foundation of a science. That's what chemists have now done. Scientists have compressed sodium chloride—rock salt—to form new compounds.

DNA clamp to grab cancer before it develops

Posted: 19 Dec 2013 10:44 AM PST

As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology.

New data compression method reduces big-data bottleneck; outperforms, enhances JPEG

Posted: 19 Dec 2013 10:12 AM PST

In creating an entirely new way to compress data, a team of researchers has drawn inspiration from physics and the arts. The result is a new data compression method that outperforms existing techniques, such as JPEG for images, and that could eventually be adopted for medical, scientific and video streaming applications.

Ways of the photoelectric effect; How physicists have learned how to select them

Posted: 19 Dec 2013 10:12 AM PST

Scientists have managed, for the first time in the history of photoelectric studies, to eliminate one serious obstacle that hampered these investigations for many years -- namely, the nuclear magnetic moment.

First cancer operation room with navigator is created

Posted: 19 Dec 2013 09:30 AM PST

A team of researchers have started the first cancer operation room with a navigator. This image-guided system will allow for increased intraoperative radiotherapy safety.

New magnetic behaviour in nanoparticles could lead to even smaller digital memories

Posted: 19 Dec 2013 06:34 AM PST

Researchers have created a new behavior in magnetic core/shell nanoparticles. It could lead to the creation of even smaller and higher capacity digital memories.

Robotic grasp: Robot picks up castors as fast as blueberries

Posted: 19 Dec 2013 06:34 AM PST

The robot effortlessly picks up one castor after another from the pile in the box and puts them into the channel. No matter how the wheels are lying, the robot manages to get an exact grip.

World's first text message using vodka: Messages sent via molecules can aid communication underground, underwater or inside the body

Posted: 18 Dec 2013 02:08 PM PST

Scientists have created a molecular communications system for the transmission of messages and data in challenging environments such as tunnels, pipelines, under water and within the body.   

First high-altitude device to help detect health threats from the sky

Posted: 17 Dec 2013 12:52 PM PST

A researcher is using the first ever high-altitude sampling device designed to collect microorganisms from the upper atmosphere, to examine the massive dust clouds that roll into Florida from Africa each year. He's looking to see if the latest plant, animal or human health threats will come from the sky.
