Seashell strength inspires stress tests

May 20, 2015 7:43 am | by Mike Williams, Rice Univ. | Comments

Mollusks got it right. They have soft innards, but their complex exteriors are engineered to protect them in harsh conditions. Engineers at the Indian Institute of Science and Rice Univ. are beginning to understand why. By modeling the average mollusk’s mobile habitat, they are learning how shells stand up to extraordinary pressures at the bottom of the sea.

Taking control of light emission

May 20, 2015 7:31 am | by David L. Chandler, MIT News Office | Comments

Researchers have found a way to couple the properties of different 2-D materials to provide an exceptional degree of control over light waves. They say this has the potential to lead to new kinds of light detection, thermal management systems and high-resolution imaging devices.

To fight bee decline, Obama proposes more land to feed bees

May 19, 2015 2:04 pm | by Seth Borenstein, AP Science Writer, Associated Press | Comments

A new federal plan aims to reverse America's declining honeybee and monarch butterfly populations by making millions of acres of federal land more bee-friendly, spending millions of dollars more on research and considering the use of fewer pesticides. While putting different type of landscapes along highways, federal housing projects and elsewhere may not sound like much in terms of action.

GE Launches the Next Evolution of Wind Energy Making Renewables More Efficient, Economic: the Digital Wind Farm

May 19, 2015 11:49 am | by GE | Comments

GE has announced the launch of its Digital Wind Farm, a dynamic, connected and adaptable wind energy ecosystem that pairs world-class turbines with the digital infrastructure for the wind industry. The technology boosts a wind farm’s energy production by up to 20 percent and could help generate up to an estimated $50 billion of value for the wind industry.

Using a new laser process to custom shape optical fibers

May 19, 2015 11:24 am | by Fraunhofer-Gesellschaft | Comments

Modern medicine relies on optical fibers to cauterize unhealthy veins in a minimally invasive way. Now, Fraunhofer researchers have developed a laser processing method that facilitates automated series manufacture of these fibers at a much finer quality than ever before. The scientists presented a fiber probe prototype manufactured using the new technique at the measurement fair SENSOR+TEST 2015 in Nuremberg.

Octopus arm inspires future surgical tool

May 19, 2015 11:08 am | by Institute of Physics | Comments

A robotic arm that can bend, stretch and squeeze through cluttered environments has been created by a group of researchers from Italy. Inspired by the eight arms of an octopus, the device has been specifically designed for surgical operations to enable surgeons to easily access remote, confined regions of the body and, once there, manipulate soft organs without damaging them.

Researchers join the hunt for “elusive” gravitational waves

May 19, 2015 10:55 am | by Cardiff University | Comments

An international project to find the first direct evidence of the existence of gravitational waves, will be officially inaugurated on May 19, 2015. Researchers at Cardiff University will use a powerful supercomputer to comb through data from two gravitational wave detectors now being brought online and will search, with unprecedented accuracy, for the first ever direct evidence of the existence of gravitational waves later this year.

Electricity generation and distribution infrastructure in the Western United States must be “climate-proofed” to diminish the risk of future power shortages, according to research by two Arizona State University engineers. Expected increases in extreme heat and drought events will bring changes in precipitation, air and water temperatures, air density and humidity.

Scientists have moved graphene—the incredibly strong and conductive single-atom-thick sheet of carbon—a significant step along the path from lab bench novelty to commercially viable material for new electronic applications. Researchers have printed a radio frequency antenna using compressed graphene ink.

Electricity generating nano-wizards: Quantum dots are an ideal nanolab

May 19, 2015 10:20 am | by Springer | Comments

Just as alchemists always dreamed of turning common metal into gold, their 19th century physicist counterparts dreamed of efficiently turning heat into electricity, a field called thermoelectrics. Such scientists had long known that, in conducting materials, the flow of energy in the form of heat is accompanied by a flow of electrons.

Researchers from Swinburne Univ. of Technology and the Univ. of Science and Technology of China have developed a low-cost technique that holds promise for a range of scientific and technological applications. They have combined laser printing and capillary force to build complex, self-assembling microstructures using a technique called laser printing capillary-assisted self-assembly (LPCS).

Study backs seaweed’s carbon capture potential

May 19, 2015 8:30 am | by Univ. of Technology, Sydney | Comments

There are great hopes for the potential of coastal plants and seaweeds to store carbon and help counter the effects of climate change and a new study is backing that potential. Scientists have carried out the first investigation of how a diverse range of coastal plants and seaweed can contribute to "blue carbon" stocks, the carbon in leaves, sediments and roots that's naturally captured, or sequestered, by plants in coastal habitats.

Artificial enzymes to reduce carbon dioxide emissions

May 19, 2015 8:14 am | by Univ. of Nottingham Malaysia Campus | Comments

Enzymes are biological catalysts that accelerate chemical reactions, such as the conversion of gaseous carbon dioxide into carbonates. Carbonates are the basic component of coral reefs, mollusc shells and kidney stones. Although naturally occurring enzymes would be ideal for converting human-generated carbon dioxide emissions into carbonates, they are generally incapable of coping with the extreme conditions of industrial plants.

A foundation for quantum computing

May 19, 2015 8:01 am | by John Toon, Georgia Institute of Technology | Comments

Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could revolutionize chemistry, biology and materials science, but the development of quantum computers has been limited by the ability to increase the number of quantum bits, or qubits, that encode, store and access large amounts of data.

Designing better medical implants

May 19, 2015 7:51 am | by Anne Trafton, MIT News Office | Comments

Biomedical devices that can be implanted in the body for drug delivery, tissue engineering or sensing can help improve treatment for many diseases. However, such devices are often susceptible to attack by the immune system, which can render them useless. A team of Massachusetts Institute of Technology researchers has come up with a way to reduce that immune-system rejection.
