When storing memories, brain prioritizes those experiences that are most rewarding
A Columbia University study finds that overnight the brain automatically preserves memories for important events and filters out the rest, revealing new insights into the processes that guide decision making and behavior.

Nature Climate Change
Is Antarctica becoming more like Greenland?
Antarctica is high and dry and mostly bitterly cold, and it's easy to think of its ice and snow as locked away in a freezer, protected from melt except around its low-lying coasts and floating ice shelves. But that view may be wrong.

Illinois professor recognized for passenger screening research after 9-11 attacks
As Professor Sheldon Jacobson watched the September 2001 terrorist attacks unfold, he was among the many Americans who realized that life was about to change. What he did not know was that a National Science Foundation-funded research project he began just days before would be part of that change, creating the groundwork for The Transportation Security Administration's PreCheck system. Precheck uses risk profiles to try to focus air security resources on higher-risk passengers.

As climate and land-use change accelerate, so must efforts to preserve California's plants
A UC Berkeley team developed a computer model that identifies the high-priority areas in California for preservation in order to save the state's native plants in the face of rapid climate change and habitat destruction. The model is based on three measures of biodiversity: genetic uniqueness (divergence), historic speciation rate (diversification) and independent evolutionary history (survival), but also includes assessments of how badly the area is degraded and thus whether it is worth the effort.

Kindergarten difficulties may predict academic achievement across primary grades
Identifying factors that predict academic difficulties during elementary school should help inform efforts to help children who may be at risk. New Penn State research suggests that children's executive functions may be a particularly important risk factor for such difficulties.

Researchers discover a new gear in life's clock: Vitamin D
Researchers at Portland State University discover that vitamin D plays a key role in embryonic development in vertebrates and by blocking vitamin D in embryos of zebrafish, researchers were able to induce dormancy in a species that doesn't enter dormancy. The discovery could have major implications in human health research.

Jumping genes shed light on how advanced life may have emerged
A previously unappreciated interaction in the genome turns out to have possibly been one of the driving forces in the emergence of advanced life. This discovery began with a curiosity for retrotransposons, known as "jumping genes," which are DNA sequences that copy and paste themselves within the genome, multiplying rapidly. Researchers inserted a retrotransposon into bacteria, and the results could give depth to the history of how advanced life may have emerged billions of years ago.

Princeton geneticist solves long-standing finch beak mystery
Princeton biologist Bridgett vonHoldt is best known for her work with canines, but when she compared the genes of large-beaked Cameroonian finches to those of their smaller-beaked counterparts, she found the answer to a 20-year old mystery: 300,000 base pairs, apparently inherited as a unit, always varied between them, and right in the middle of that genetic sequence was the well-known growth factor, IGF-1.

Antarctic melting slows atmospheric warming and speeds sea level rise
Current climate models do not include the effects on the global climate of melting ice from Antarctica. The new research is the first to project how the melting of the Antarctic ice sheet will affect future climate. The researchers found that the entire Earth will continue warming, but the atmosphere will warm more slowly because more of the heat will be trapped in the ocean.

The 'Swiss Army knife of prehistoric tools' found in Asia, suggests homegrown technology
A study by an international team of researchers, including from the University of Washington, determines that carved stone tools, also known as Levallois cores, were used in Asia 80,000 to 170,000 years ago. With the find -- and absent human fossils linking the tools to migrating populations -- researchers believe people in Asia developed the technology independently, evidence of similar sets of skills evolving throughout different parts of the ancient world.

Rare and diverse giant viruses unexpectedly found in a forest soil ecosystem
Until recently, scientists thought of viruses as mostly small infectious agents, tiny compared to typical bacteria and human cells. So imagine the surprise when biologist Jeff Blanchard and Ph.D. student Lauren Alteio at the University of Massachusetts Amherst, with others at the US Department of Energy's (DOE) Joint Genome Institute (JGI), discovered giant viruses -- relatively speaking the size of Macy's parade day balloons -- in soil at Harvard Forest in Petersham, Massachusetts.

Half of the world's annual precipitation falls in just 12 days, new study finds
Currently, half of the world's measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By century's end, climate models project that this lopsided distribution of rain and snow is likely to become even more skewed, with half of annual precipitation falling in 11 days.
