 Proceedings of the National Academy of Sciences{DISSERTATION} Later Stone Age got earlier start in South Africa than thought The Later Stone Age emerged in South Africa more than 20,000 years earlier than previously believed -- about the same time humans were migrating from Africa to the European continent, says a new international study led by the University of Colorado Boulder.

Nature Materials{DISSERTATION} How to avoid traps in plastic electronics Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw: The electronic current is influenced by "charge traps" in the material. New research reveals a common mechanism underlying these traps and provides a theoretical framework to design trap-free plastic electronics.

Nature Geoscience{DISSERTATION} Chronic 2000-04 drought, worst in 800 years, may be the 'new normal' The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the "new normal" for most of the coming century. Such climatic extremes have increased as a result of global warming, and as bad as conditions were during the 2000-04 drought, they may eventually be seen as the good old days.

The Holocene{DISSERTATION} When the world burned less In the years after Columbus' voyage, burning of New World forests and fields diminished significantly – a phenomenon some have attributed to decimation of native populations by European diseases. But a new University of Utah-led study suggests global cooling resulted in fewer fires because both preceded Columbus in many regions worldwide.

Blood{DISSERTATION} Tumor cells' inner workings predict cancer progression Using a new assay method to study tumor cells, researchers at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center have found evidence of clonal evolution in chronic lymphocytic leukemia (CLL). The assay method distinguishes features of leukemia cells that indicate whether the disease will be aggressive or slow-moving, a key factor in when and how patients are treated.

Proceedings of the National Academy of Sciences{DISSERTATION} Molecule found that inhibits recovery from stroke Researchers at UCLA have identified a novel molecule in the brain that, after stroke, blocks the formation of new connections between neurons. As a result, it limits the brain's recovery. In a mouse model, the researchers showed that blocking this molecule -- called ephrin-A5 -- induces axonal sprouting, that is, the growth of new connections between the brain's neurons, or cells, and as a result promotes functional recovery.

Nano Letters{DISSERTATION} Photovoltaics from any semiconductor Berkeley Lab researchers have developed a technology that enables low-cost, high efficiency solar cells to be made from virtually any semiconductor material. This opens the door to the use of plentiful, relatively inexpensive semiconductors previously considered unsuitable for photovoltaics.

Science{DISSERTATION} Big horns trump smooth pickup lines every time Elk and rhinoceros beetles aren't diabetic, but to grow big horns and attract mates it appears that the males are insulin-dependent. Ian Dworkin, Michigan State University zoologist, was part of a team that for the first time ever showed why horns -- from elk to rhinoceros beetles -- and other decorative, mate-attracting structures are sensitive to changes in nutrition. As reported in the current issue of Science, the key ingredient for this growth is insulin.

Environmental Science and Policy{DISSERTATION} Environmental groups should pool efforts to reach the public A lot of time, effort, and money are spent by agencies, municipalities, and other non-governmental organizations to inform and educate the public about environmental concerns. Could these groups collaborate to inform the public about an environmental concern even though their beliefs may be very different? Two studies suggest that they can and should.

Science{DISSERTATION} Researchers discover biological mechanism for growing massive animal weapons, ornaments In the animal kingdom, huge weapons such as elk antlers or ornaments like peacock feathers are sexy. Their extreme size attracts potential mates and warns away lesser rivals. Now researchers led by scientists at the University of Montana and Washington State University have discovered a developmental mechanism they think may be responsible for the excessive growth of threatening horns or come-hither tail feathers.

But in a new study, University of Pennsylvania biologist Daniel Janzen joins more than 200 colleagues to report that protected areas are still vulnerable to damaging encroachment, and many are suffering from biodiversity loss.

Earth and Planetary Science Letters{DISSERTATION} 2 Solar System puzzles solved How did icy comets obtain particles that formed at high temperatures, and how did the particles acquire rims with different compositions? Carnegie scientists are the first to model the trajectories of refractory particles in the unstable disk that formed the Solar System. They found particles could have been processed in the hot inner disk, and then traveled to the frigid outer regions to end up in icy comets. Their meanderings could help explain the different rims.

Psychological Bulletin{DISSERTATION} Spatial skills may be improved through training, new review finds Spatial skills -- those involved with reading maps and assembling furniture -- can be improved if you work at it, that's according to a new look at the studies on this topic by researchers at Northwestern University and Temple. Improving spatial skills is important because children who do well at spatial tasks such as putting together puzzles are likely to achieve highly in science, technology, engineering and mathematics fields.

Nature Geoscience{DISSERTATION} Spillways can divert sand from river to rebuild wetlands Researchers could have a new method to rebuild wetlands of the Louisiana delta, thanks to a chance finding during severe flooding of the Mississippi River. Civil engineers and geologists from the University of Illinois, in collaboration with the US Army Corps of Engineers, found that when the Bonnet Carre spillway was opened in 2011, a high percentage of the river's sand load diverted into the spillway – a goal of research work to build up wetlands.
