2013 AAAS Annual Meeting{DISSERTATION} Malawi's bountiful harvests and healthier children In Malawi, the fields are full -- and so are the children. Through research led by Michigan State University, crop yields have increased dramatically. The children of Ekwendi, Malawi, also have gained weight and are taller. These improvements bring smiles to Sieglinde Snapp, MSU ecologist, and other researchers who have worked in Malawi for many years.

Physical Review Letters{DISSERTATION} Force is the key to granular state-shifting Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It's because granular materials -- like sand or dirt -- can change their behavior, or state. Researchers from North Carolina State University have found that the forces individual grains exert on one another are what most affect that transition.

Nucleic Acids Research{DISSERTATION} A microbial biorefinery provides new insight into how bacteria regulate genes New research reveals the genetic and chemical mechanisms through which some bacteria consume lignin, a highly stable polymer that accounts for up to a third of plant biomass. Microorganisms that can break down plant biomass into the precursors of biodiesel or other commodity chemicals might one day be used to produce alternatives to petroleum.

SIAM Journal on Applied Mathematics{DISSERTATION} Math helps detect gang-related crime and better allocate police resources Social groups in a population can lend important cues to law enforcement officials, consumer-based services and risk assessors. Social and geographical patterns that provide information about such communities or gangs have been a popular subject for mathematical modeling. In a paper published last month in the SIAM Journal on Applied Mathematics, authors use police department records about individuals' social and geographical information to determine gang memberships.

Geology{DISSERTATION} Penn geologists quantify, characterize sediment carried by Mississippi flood to Louisiana's wetlands The spring 2011 flood on the Mississippi was among the largest floods ever, the river swelling over its banks and wreaking destruction in the surrounding areas. But a University of Pennsylvania-led study also shows that the floods reaped environmental benefits -- transporting and laying down new sediment in portions of the Delta -- that may help maintain the area's wetlands.

These materials, called organic topological insulators, could shuttle information at the speed of light in quantum computers and other high-speed electronic devices.

Proceedings of the National Academy of Sciences{DISSERTATION} Long noncoding RNAs control development of fat cells Whitehead Institute researchers report that 10 long noncoding RNAs (lncRNAs) play a vital role in the regulation of white fat cells. When each of these lncRNAs is individually knocked down, fat precursor cells fail to mature into white fat cells and have significantly reduced lipid droplets compared with white fat cells with unmodified lncRNA function.

BMC Medicine{DISSERTATION} Flu outbreaks modeled by new study of classroom schedules Classroom rosters combined with human-networking theory may give a clearer picture of just how infectious diseases such as influenza can spread through a closed group of people, and even through populations at large. Using high-school schedule data for a community of students, teachers, and staff, Penn State University scientists have developed a low-cost but effective method to determine how to focus disease-control strategies based on which individuals are most likely to spread the infection.

{DISSERTATION} HIPPO global-scale air chemistry dataset now available Data from the HIAPER Pole-to-Pole Observations study of greenhouse gases and aerosols are now available to the atmospheric research community and the public. This comprehensive dataset provides the first high-resolution, vertically resolved measurements of over 90 unique atmospheric species collected during a series of nearly pole-to-pole flights over the Pacific Ocean, across all seasons. The suite of atmospheric trace gases and aerosols is pertinent to understanding the carbon cycle and challenging global climate models.

First an early warning that matches the intruder's song, then wing waving – a bird's version of "flipping the bird" – as the dispute heats up, and finally, if all other signals have failed, attack.

{DISSERTATION} New world record efficiency for thin film silicon solar cells EPFL's Institute of Microengineering has reached a remarkable 10.7 percent efficiency single-junction microcrystalline silicon solar cell, clearly surpassing the previous world record of 10.1 percent held by the Japanese company Kaneka Corporation since 1998. Such significant efficiency, independently certified by the Fraunhofer Institute for Solar Energy Systems, was achieved with less than two micrometers of photovoltaic active material – 100 times less than with standard techniques.

Biology Letters{DISSERTATION} Size of lunch dictates force of crunch Even in the same animal, not all bites are the same. A new study finds that because the force in a muscle depends on how much it is stretched, an animal's bite force depends on the size of what it is biting. The finding has direct implications for ecology and evolution.
