 Proceedings of the National Academy of SciencesUnfrozen mystery: H2O reveals a new secret Using revolutionary new techniques, a team led by Carnegie's Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years. Their findings could alter our understanding of how the water molecule responds to conditions found deep within planets and could have implications for energy science.

Nature GeneticsSelf-fertilizing plants contribute to their own demise Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy -- known as selfing -- guarantees reproduction but, over time, leads to reduced diversity and the accumulation of harmful mutations. A new study published in the scientific journal Nature Genetics shows that these negative consequences are apparent across a selfing plant's genome, and can arise more rapidly than previously thought.

IEEE Conference on Intelligence and Security InformaticsMaking sense of patterns in the Twitterverse If you think keeping up with what's happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by seven billion -- and you'll have a sense of what Court Corley wakes up to every morning. Corley has created a powerful digital system, dubbed SALSA, capable of analyzing billions of tweets and other messages in just seconds, in an effort to discover patterns and make sense of all the information.

Indoor AirMore fresh air in classrooms means fewer absences If you suspect that opening windows to let in fresh air might be good for you, a new study by scientists at Lawrence Berkeley National Laboratory has confirmed your hunch. Analyzing extensive data on ventilation rates collected from more than 150 classrooms in California over two years, the researchers found that bringing classroom ventilation rates up to the state-mandated standard may reduce student absences due to illness by approximately 3.4 percent.

Nature CommunicationsIncreased NMR/MRI sensitivity through hyperpolarization of nuclei in diamond Berkeley Lab researchers have demonstrated the first magnetically-controlled nearly complete hyperpolarization of the spins of carbon-13 nuclei located near synthetic defects in diamond crystals. This spin hyperpolarization, which can be carried out with refrigerator-style magnets at room temperature, enhances NMR/MRI sensitivity by many orders of magnitude.

Proceedings of the National Academy of SciencesSpintronics approach enables new quantum technologies A team of researchers including members of the University of Chicago's Institute for Molecular Engineering highlight the power of emerging quantum technologies in two recent papers published in the Proceedings of the National Academy of Sciences (PNAS). These technologies exploit quantum mechanics, the physics that dominates the atomic world, to perform disparate tasks such as nanoscale temperature measurement and processing quantum information with lasers.

Journal of the American Ceramic SocietyRoman seawater concrete holds the secret to cutting carbon emissions At Lawrence Berkeley National Laboratory's Advanced Light Source, scientists analyzed samples from a Roman breakwater submerged in the Bay of Naples for over two millennia, revealing the secrets of crystal chemistry that allow Roman seawater concrete to resist chemical attack and wave action for centuries. Materials and processes for manufacturing extraordinarily durable Roman maritime concrete released much less carbon than most modern concrete, presenting important opportunities for better quality and reduction of atmospheric carbon.

Nature CommunicationsStanford scientists create novel silicon electrodes that improve lithium-ion batteries Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products. The scientists developed a new technique for producing low-cost, silicon-based batteries with potential applications for a wide range of electrical devices.

Physical Review LettersDense hydrogen in a new light Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich planets. New work from Carnegie scientists using intense infrared radiation shines new light on this fundamental material at extreme pressures and reveals the details of a surprising new form of solid hydrogen.

ACS NanoNano-engineering boosts efficiency of materials that convert waste heat to electrical energy High-performance thermoelectric materials that convert waste heat to electricity could one day be a source of more sustainable power. But they need to be a lot more efficient before they could be effective on a broad scale in places like power plants or military bases, researchers say.

ScienceScientists capture first images of molecules before and after reaction Using atomic force microscopy, chemists for the first time can capture images of molecules before and after they react, which will allow them to better tune reactions to get the products they want. UC Berkeley chemist Felix Fischer and physicist Michael Crommie joined forces to develop the technique, which could help scientists study and improve catalytic reactions like those used widely in industry to make chemicals or crack oil.
