 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

Proceedings of the Royal Society BHow infidelity helps nieces and nephews A University of Utah study produced new mathematical support for a theory that explains why men in some cultures often feed and care for their sisters' children: where extramarital sex is common and accepted, a man's genes are more likely to be passed on by their sister's kids than by their wife's kids.

Proceedings of the National Academy of SciencesTo get the best look at a person's face, look just below the eyes, according to UCSB researchers They say that the eyes are the windows to the soul. However, to get a real idea of what a person is up to, according to UC Santa Barbara researchers Miguel Eckstein and Matt Peterson, the best place to check is right below the eyes. Their findings are published in the Proceedings of the National Academy of Sciences. Contact: Sonia Fernandez

Acta BiotheoreticaModel sheds light on the chemistry that sparked the origin of life The question of how life began on a molecular level has been a longstanding problem in science. However, recent mathematical research sheds light on a possible mechanism by which life may have gotten a foothold in the chemical soup that existed on the early Earth. Contact: Robin Ann Smith

Physical Review LettersModeling the breaking points of metallic glasses Metallic glass alloys (or liquid metals) are three times stronger than the best industrial steel, but can be molded into complex shapes with the same ease as plastic. These materials are highly resistant to scratching, denting, shattering and corrosion. Mathematical methods developed by a Berkeley Lab scientists will help explain why liquid metals have wildly different breaking points. Contact: Linda Vu

Learning and InstructionStar Trek Classroom: The next generation of school desks Researchers designing and testing the 'classroom of the future' have found that multi-touch, multi-user desks can boost skills in mathematics. New results from a three-year project working with over 400 pupils, mostly eight-10 year olds, show that collaborative learning increases both fluency and flexibility in maths. It also shows that using an interactive 'smart' desk can have benefits over doing mathematics on paper.

ScienceStudy reveals the proteins expressed by human cytomegalovirus New findings reveal the surprisingly complex protein-coding capacity of the human cytomegalovirus and provide the first steps toward understanding how the virus manipulates human cells during infection. The related study appears in the Nov. 23 issue of the journal Science, which is published by AAAS, the nonprofit science society. Contact: Natasha Pinol

NatureNew structures self-assemble in synchronized dance With self-assembly guiding the steps and synchronization providing the rhythm, a new class of materials forms dynamic, moving structures in an intricate dance. Researchers from the University of Illinois and Northwestern University have demonstrated tiny spheres that synchronize their movements as they self-assemble into a spinning microtube. Such in-motion structures, a blending of mathematics and materials science, could open a new class of technologies with applications in medicine, chemistry and engineering.

Strengthening Canada's research capacity: The gender dimension A newly released report by the Council of Canadian Academies entitled, Strengthening Canada's Research Capacity: The Gender Dimension provides an assessment of the the factors that influence university research careers of women. This authoritative assessment has found that although there has been progress in the representation of women in the university research ranks, there are still gender equity challenges that must be overcome and the passage of time will not be enough to ensure parity.

Physical Review LettersBaBar experiment confirms time asymmetry Digging through nearly 10 years of data from billions of BaBar particle collisions, researchers found that certain particle types change into one another much more often in one way than they do in the other, a violation of time reversal symmetry and confirmation that some subatomic processes have a preferred direction of time.

Nature NeuroscienceA better thought-controlled computer cursor Stanford researchers have designed the fastest, most accurate algorithm yet for brain-implantable prosthetic systems that can help disabled people maneuver computer cursors with their thoughts. The algorithm's speed, accuracy and natural movement approach those of a real arm, and the system avoids the long-term performance degradations of earlier technologies.

PLOS ONEBasketball teams offer insights into building strategic networks What started out as a project to teach undergraduate students about network analysis, turned into an in-depth study of whether it was possible to analyze a National Basketball Association basketball team's strategic interactions as a network. Arizona State University researchers discovered it is possible to quantify both a team's cohesion and communication structure. Contact: Sandra Leander

Transportation ResearchStudy: Cellphone bans associated with fewer urban accidents Cellphones and driving go together like knives and juggling. But when cellphone use is banned, are drivers any safer? It depends on where you're driving, a study by University of Illinois researchers says. The study found that, long-term, enacting a cellphone ban was associated with a relative decrease in the accident rate in urban areas. However, in very rural areas, cellphone bans were associated with higher accident rates than would otherwise be expected. Contact: Liz Ahlberg

Environmental Science and TechnologyAirborne particles smuggle pollutants to far reaches of globe Pollution from fossil fuel burning and forest fires reaches all the way to the Arctic, even though it should decay long before it travels that far. Now, lab research can explain how pollution makes its lofty journey: rather than ride on the surface of airborne particles, pollutants snuggle inside, protected from the elements on the way. The results will help scientists improve atmospheric air-quality and pollution transport models.

European Space Agency conference on Earth Observation and Cryosphere Science Environmental Research LettersWarming temperatures will change Greenland's face Global climate models abound. What is harder to pin down, is how a warmer global temperature might affect any specific region on Earth. Dr. Marco Tedesco, associate professor of earth and atmospheric sciences, and a colleague have made the global local. Using a combination of climate models, they predict how different greenhouse gas scenarios would change the face of Greenland and impact sea level rise.
