 Nature ChemistryA better way to make chemicals? For the first time, scientists have studied a mechanochemical milling reaction in real time, using highly penetrating X-rays to observe the surprisingly rapid transformations as the mill mixed, ground, and transformed simple ingredients into a complex product. This research, reported in Nature Chemistry, promises to advance scientists' understanding of processes central to the pharmaceutical, metallurgical, cement and mineral industries – and could open new opportunities in "green chemistry" and environmentally friendly chemical synthesis.

Nature ChemistryA shock to pollution in chemistry Solvents are everywhere in chemistry and a major environmental concern. High-frequency milling is an energy-efficient alternative: the impact of steel balls in a rapidly moving jar drives reactions. Direct observation of the underlying chemistry is difficult but scientists used X-rays to observe, for the first time, in real time the chemistry when a mill mixes, grinds and transforms simple ingredients into a complex product. The study opens new opportunities in Green Chemistry and environmentally-friendly synthesis. Contact: Claus habfast

NASA's TRMM satellite video reveals 2012 hurricane season rainfall The 2012 Atlantic Hurricane season was a busy one as there were 19 tropical cyclones. A new NASA animation using data from the Tropical Rainfall Measuring Mission satellite known as TRMM shows rainfall from tropical cyclones in the western Atlantic, as measured from space.

NASA sees 'hot towers' in intensifying Typhoon Bopha Bopha intensified into a typhoon today, Nov. 30, as it continues to affect the islands in Micronesia in the western North Pacific Ocean. NASA's TRMM satellite captured rainfall data of Bopha and noticed "Hot Tower" thunderstorms as it was intensifying from a tropical storm into a typhoon.

Computers and Electronics in AgricultureA digital portrait for grapes indicates their ripeness Researchers at the University of Seville (Spain) have developed a technique for estimating grape composition and variety using computer imaging. They have also put forward an index for identifying the ripeness of seeds without the need for chemical analysis. This new method can help to decide the best moment for picking. Contact: SINC

Advanced MaterialsPredicting material fatigue A small crack in a metal wheel caused Germany's worst-ever rail accident -- the 1998 Eschede train disaster. The problem: it was practically impossible to detect damage of that nature to a metal by inspecting it externally. But now scientists have succeeded in making material fatigue visible. They designed new synthetic materials that emit light to report high mechanical stress.

ACS Applied Materials & InterfacesAdapting fish defenses to block human infections Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses, including antimicrobial peptides located in their gills. Undergraduate researchers at Worcester Polytechnic Institute are studying the biology and mechanics of one of those peptides with the aim of creating engineered surfaces that can kill bacteria responsible for foodborne illnesses and hospital-acquired infections. The team reports its latest findings online in the journal ACS Applied Materials & Interfaces.

FASEB JournalInsects beware: The sea anemone is coming Insects are becoming resistant to insecticides, presenting a growing need to develop novel ways of pest control. New research in The FASEB Journal shows that the sea anemone's venom harbors toxins that could pose a new generation of environmentally friendly insecticides, which avoid insect resistance. These toxins disable ion channels that mediate pain and inflammation, and could also spur drug development aimed at pain, cardiac disorders, epilepsy and seizure disorders, and immunological diseases.

Maths helps mobiles & tablets match eyes' ability to switch from sunshine to shadow Researchers have pushed the boundaries of High Dynamic Range (HDR) video to match our own eyes' ability to cope with the real world's ever rapidly changing light intensity -- such as sun simply going behind clouds. Now researchers at WMG at the University of Warwick, have found a way to compress and stream HDR video directly to monitors and mobile devices, such as an iPad, bringing enormous benefits to industries including gaming and security.

Science China: Information SciencesMethod for accurate extraction of a target profile developed at Beijing Institute of Technology The detection and recognition of an object with small radar cross-section (RCS) is a difficult problem. In the 2012(10) issue of Science China, a paper proposes a novel imaging algorithm to extract the target profile using the shadow inverse synthetic aperture signal in forward-scatter radar. The algorithm is an effective tool with which to detect and recognize an object with a small RCS, such as a stealth target or an unmanned aerial vehicle.

Science China: Information SciencesA new anti-windup design paradigm for control systems with actuator saturation was developed The traditional anti-windup scheme involves a single anti-windup loop designed for activation immediately at the occurrence of actuator saturation. In the September 2012 issue of SCIENCE CHINA Information Sciences, a new anti-windup design paradigm was developed that includes three anti-windup loops, simultaneously designed for immediate, delayed and anticipatory activations, and results in significantly improved closed-loop system performances.
