Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a “nano-shish-kebab,” consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire. However, the nanowire and nanosheets are actually a single, three-dimensional structure consisting of a seamless series of germanium sulfide (GeS) crystals. The structure holds promise for use in the creation of new, three-dimensional (3-D) technologies.

The researchers believe this is the first engineered nanomaterial to combine one-dimensional and two-dimensional structures in which all of the components have a shared crystalline structure. (more…)

USGS Estimates 162 Billion Short Tons of Recoverable Coal in the Powder River Basin

New basin-wide assessment of recoverable resources and reserves

The Powder River Basin of Wyoming and Montana contains about 162 billion short tons (BST) of recoverable coal from a total of 1.07 trillion short tons of in-place resources according to a new USGS assessment. This assessment also estimates that 25 BST of those resources are currently economical to recover, the first such estimate released by the USGS for coal for an entire basin.

The Powder River Basin—a large geologic feature located in northeastern Wyoming and southeastern Montana—contains the largest deposits of low-sulfur subbituminous coal in the world. This study is significant because it illustrates that only a relatively small percentage of in-place coal resources are technically and economically recoverable. (more…)

Yammer Announces Message Translation to Ignite Multilingual Collaboration

Uses Microsoft Translator technology to support 39 languages.

SAN FRANCISCO — Feb. 28, 2013 — Yammer, Inc., a best-in-class Enterprise Social Network and part of the Microsoft Office Division, today announced plans to add message translation capabilities, which will allow users to instantly translate Yammer conversations into their native languages.

“Removing language as a barrier to cross-company collaboration can be a competitive game changer for multinational organizations. It opens a world of possibilities,” said Adam Pisoni, Yammer co-founder and general manager of Engineering, Microsoft Office Division. “This is another example of Yammer’s accelerated innovation following the Microsoft acquisition — we’re able to use Microsoft Translator to quickly deliver additional value to customers.” (more…)

How a ‘motor mouth’ is changing dentistry

If you want your dental fillings, crowns, implants, and so on to last, you can thank ART.

Chewing involves some of the human body’s most complex motions, and ART, the artificial mouth at the University of Minnesota School of Dentistry, can perform a year’s worth of chewing—300,000 cycles—in just a day or two. (more…)

Mindfulness meditation training in awareness of present moment experience, such as body and breath sensations, prevents depression and reduces distress in chronic pain. In a new paper, Brown University scientists propose a neurophysiological framework to explain these clinical benefits. (more…)

NASA’s NuSTAR Helps Solve Riddle of Black Hole Spin

PASADENA, Calif. — Two X-ray space observatories, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency’s XMM-Newton, have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our sun.

The supermassive black hole lies at the dust- and gas-filled heart of a galaxy called NGC 1365, and it is spinning almost as fast as Einstein’s theory of gravity will allow. The findings, which appear in a new study in the journal Nature, resolve a long-standing debate about similar measurements in other black holes and will lead to a better understanding of how black holes and galaxies evolve.

March of the Pathogens: Parasite Metabolism Can Foretell Disease Ranges under Climate Change

Knowing the temperatures that viruses, bacteria, worms and all other parasites need to grow and survive could help determine the future range of infectious diseases under climate change, according to new research.

Princeton University researchers developed a model that can identify the prospects for nearly any disease-causing parasite as the Earth grows warmer, even if little is known about the organism. Their method calculates how the projected temperature change for an area would alter the creature’s metabolism and life cycle, the researchers report in the journal Ecology Letters. (more…)
