'Chameleon of the sea' reveals its secrets

Posted: 28 Jan 2014 05:20 PM PST

Scientists hope new understanding of the natural nanoscale photonic device that enables a small marine animal to dynamically change its colors will inspire improved protective camouflage for soldiers on the battlefield.

New NASA laser technology reveals how ice measures up

Posted: 28 Jan 2014 03:48 PM PST

A new photon-counting technique will allow researchers to track the melt or growth of Earth's frozen regions.

Active power control of wind turbines can improve power grid reliability

Posted: 28 Jan 2014 09:46 AM PST

Scientists have completed a comprehensive study to understand how wind power technology can assist the power grid by controlling the active power output being placed onto the system. The rest of the power system's resources have traditionally been adjusted around wind to support a reliable and efficient system. The research that led to this report challenges that concept.

Research could bring new devices that control heat flow

Posted: 28 Jan 2014 08:33 AM PST

Researchers are proposing a new technology that might control the flow of heat the way electronic devices control electrical current, an advance that could have applications in a diverse range of fields from electronics to textiles.

New imaging technique speeds removal of non-melanoma skin cancers

Posted: 28 Jan 2014 08:32 AM PST

Skin cancer surgery involves successive removal of tissue, which is processed using a 45-minute procedure to determine if residual cancer remains and is often repeated several times. Now, researchers have developed a microscopic technique that identifies residual cancer tissue in 90 seconds, promising to dramatically reduce the length, inefficiency, and cost of this common surgery.

Filleting robot to help the Norwegian fishing industry

Posted: 28 Jan 2014 07:33 AM PST

A newly developed white fish filleting machine could give this Norwegian industry a much-needed boost. Unlike farmed salmon, white fish varies greatly in size and weight. This means that until now, no one has been able to develop a machine that can fillet these fish.

Vacuum technology removes dangerous blood clots in heart

An innovative vacuum technology can remove potentially deadly, large clots.

Flexible, transparent conductor created: Discovery brings bendable cell phone, foldable flat-screen TV closer to reality

Posted: 28 Jan 2014 06:47 AM PST

Researchers have developed a new stretchable and transparent electrical conductor, bringing the potential for a fully foldable cell phone or a flat-screen television that can be folded and carried under your arm closer to reality.

Sensor detects salt on the road to avoid excess

Posted: 28 Jan 2014 06:46 AM PST

Engineers have designed an optical sensor that detects how much salt is on road surfaces in real time. This avoids the need to spread the substance excessively, because although this prevents ice from forming on roads, it can also harm vehicles, infrastructure and the environment.

Computing with silicon neurons: Scientists use artificial nerve cells to classify different types of data

Posted: 28 Jan 2014 06:45 AM PST

Scientists in Germany are using artificial nerve cells to classify different types of data. These silicon 'neurons' could recognize handwritten numbers, or distinguish plant species based on their flowers.

Microwires as mobile phone sensors

Posted: 28 Jan 2014 06:45 AM PST

A new study is making progress in furthering understanding of the surface magnetic behavior of glass-coated microwires and has concluded that they are the major candidates for use as high sensitivity sensors, in mobile phones, for example.

Active supermassive black holes revealed in merging galaxies

Posted: 28 Jan 2014 06:43 AM PST

Astronomers have conducted infrared observations of luminous, gas-rich, merging galaxies to study active, mass-accreting supermassive black holes (SMBHs). They found that at least one SMBH almost always becomes active and luminous by accreting a large amount of material.

Using silver nanoparticles, researchers create cream that avoids transmission of HIV

Posted: 28 Jan 2014 06:43 AM PST

After discovering that silver nanoparticles are capable of blocking the entry of HIV into organisms, a group of researchers created a vaginal cream to control the transmission of the virus. The product has proven efficiency in lab tests, although clinical trials are yet to be performed.

Exhaled breath may help identify early lung cancer

Posted: 28 Jan 2014 06:41 AM PST

Specific compounds found in exhaled breath may help diagnose lung cancer in its early stages. The discovery was made when researchers examined patients with suspicious lung lesions.

DNA-built nanostructures safely target, image cancer tumors

Posted: 27 Jan 2014 01:48 PM PST

A team of researchers has discovered a method of assembling "building blocks" of gold nanoparticles as the vehicle to deliver cancer medications or cancer-identifying markers directly into cancerous tumors.

First ever implantation of new device for thoracic aneurysm performed in Michigan

Posted: 27 Jan 2014 01:45 PM PST

A new device tested first at the University of Michigan may provide a minimally invasive option for the elderly who are facing life-threatening thoracic aneurysms.
