New step towards future production of solar fuels

January 26, 2015 9:31 am | by Linda Koffmar, Uppsala Univ. | News | Comments

One way of storing solar energy is to transform the energy directly into a fuel. Researchers at Uppsala Univ. have shown a reaction which makes the process of creating fuel from solar energy more efficient and less energy demanding. Solar energy is abundant. In one hour, the Earth receives as much energy from the sun as humankind uses in a whole year.

Chemists find a way to unboil eggs

January 26, 2015 9:25 am | by Janet Wilson, Univ. of California, Irvine | News | Comments

Univ. of California, Irvine and Australian chemists have figured out how to unboil egg whites, an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion global biotechnology industry, according to findings published in ChemBioChem.

Possible drone found on White House grounds

January 26, 2015 9:17 am | by Nedra Pickler, Associated Press | News | Comments

A device, possibly an unmanned aerial drone, was found on the White House grounds during the middle of the night while President Barack Obama and the first lady were in India, but his spokesman said today that it posed no threat. It was unclear whether their daughters, Sasha and Malia, were at home at the time of the incident with their grandmother, Marian Robinson, who also lives at the White House.

Entanglement on a chip

January 26, 2015 9:12 am | by Lyndsay Meyer, The Optical Society | News | Comments

Unlike Bilbo's magic ring, which entangles human hearts, engineers have created a new microring that entangles individual particles of light, an important first step in a whole host of new technologies. Entanglement is one of the most intriguing and promising phenomena in all of physics. Properly harnessed, entangled photons could revolutionize computing, communications and cyber security.

Chromium-centered cycloparaphenylene rings for making functionalized nanocarbons

January 26, 2015 8:51 am | by Institute of Transformative Biomolecules, Nagoya Univ. | News | Comments

A team of chemists at Nagoya Univ. has synthesized novel transition metal-complexed cycloparaphenylenes (CPPs) that enable selective monofunctionalization of CPPs for the first time, opening doors to the construction of unprecedented nanocarbons. The team has synthesized novel CPP chromium complexes and demonstrated their utility in obtaining monofunctionalized CPPs, which could be useful for making carbon nanotubes.

How cancer turns good cells to the dark side

January 26, 2015 8:38 am | by Mike Williams, Rice Univ. | News | Comments

Cancer uses a little-understood element of cell signaling to hijack the communication process and spread, according to Rice Univ. researchers. A new computational study by researchers at the Rice-based Center for Theoretical Biological Physics shows how cancer cells take advantage of the system by which cells communicate with their neighbors as they pass messages to “be like me” or “be not like me.”

Scientists shed new light on biomass breakdown

January 26, 2015 8:18 am | by David Garner, Senior Press Officer, Univ. of York | News | Comments

Scientists at the Univ. of York are part of a research team which has found that a recently discovered family of enzymes can degrade resistant forms of starch. Earlier research established that the enzymes, lytic polysaccharide monooxygenases (LPMOs), are able to degrade hard-to-digest biomass into its constituent sugars.

Improvements in transistors will make flexible plastic computers a reality

January 26, 2015 8:11 am | by National Institute for Materials Science | News | Comments

Researchers in Japan revealed that improvements should soon be expected in the manufacture of transistors that can be used, for example, to make flexible, paper-thin computer screens. The scientists reviewed the latest developments in research on photoactive organic field-effect transistors, devices that incorporate organic semiconductors, amplify weak electronic signals and either emit or receive light.

Engineering discovery brings invisibility closer to reality

January 26, 2015 8:01 am | by Pete Brown, UA College of Engineering | News | Comments

Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, acoustic and other types of waves in ways not possible in nature. Now, a discovery has been made with these synthetic materials that may take engineers one step closer to building microscopes with superlenses.

Structure control unlocks magnetization, polarization simultaneously

January 26, 2015 7:53 am | by Univ. of Liverpool | News | Comments

Scientists at the Univ. of Liverpool have controlled the structure of a material to simultaneously generate both magnetization and electrical polarization, an advance which has potential applications in information storage and processing. The researchers demonstrated that it's possible to unlock these properties in a material which initially displayed neither by making designed changes to its structure.

Navy wants to increase use of sonar-emitting buoys

January 25, 2015 12:18 pm | by Phuong Le, Associated Press | News | Comments

The U.S. Navy is seeking permits to expand sonar and other training exercises off the Pacific Coast, a proposal raising concerns from animal advocates who say that more sonar-emitting buoys would harm whales and other creatures that live in the water. The Navy wants to deploy up to 720 sonobuoys at least 12 nautical miles off the coasts of Washington, Oregon and Northern California.

Infrared imaging technique operates at high temperatures

January 23, 2015 4:19 pm | by Amanda Morris, Northwestern Univ. | News | Comments

From aerial surveillance to cancer detection, mid-wavelength infrared (MWIR) radiation has a wide range of applications. And as the uses for high-sensitivity, high-resolution imaging continue to expand, MWIR sources are becoming more attractive. Currently, commercial technologies for MWIR detection can only operate at cryogenic temperatures in order to reduce thermal and electrical noise.

Graphene edges can be tailor-made

January 23, 2015 3:27 pm | by Mike Williams, Rice Univ. | News | Comments

Theoretical physicists at Rice Univ. are living on the edge as they study the astounding properties of graphene. In a new study, they figure out how researchers can fracture graphene nanoribbons to get the edges they need for applications. New research shows it should be possible to control the edge properties of graphene nanoribbons by controlling the conditions under which the nanoribbons are pulled apart.

After oil spill, company says new line will be safer

January 23, 2015 2:17 pm | by Matthew Brown, Associated Press | News | Comments

A Wyoming company said Friday it will replace a pipeline that spilled almost 40,000 gallons of oil into a river in Montana with a new line buried more deeply to protect against future accidents. The Jan. 17 spill into the Yellowstone River contaminated the water supply for 6,000 residents of Glendive in eastern Montana.

Calculating the future of solar-fuel refineries

January 23, 2015 2:01 pm | by Scott Gordon, Univ. of Wisconsin-Madison | News | Comments

A team of Univ. of Wisconsin-Madison engineers has developed a new tool to help plot the future of solar fuels. In a paper recently published in Energy & Environmental Science, a team outlined a tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries.
