Mathematical 'Gingko trees' reveal mutations in single cells that characterize diseases
Scientists at CSHL publish a new interactive analysis program called Gingko that reduces the uncertainty of single-cell analysis and provides a simple way to visualize patterns in copy number mutations across populations of cells. Detailed knowledge of CNVs can point to specific treatment regimens.

Poison in the Arctic and the human cost of 'clean' energy
Harvard research suggests that high levels of methylmercury, a potent neurotoxin, in Arctic life are a byproduct of global warming and the melting of sea-ice in Arctic and sub-Arctic regions. To mitigate global warming, many governments are turning to hydroelectric power but this research also suggests that flooding for hydroelectric development will put even more methylmercury into ecosystems than climate change.

Study shows common molecular tool kit shared by organisms across the tree of life
Researchers have discovered the assembly instructions for nearly 1,000 protein complexes shared by most kinds of animals, revealing their deep evolutionary relationships. Those instructions offer a powerful new tool for studying the causes of diseases such as Alzheimer's, Parkinson's and cancer.

New medical device concept could reduce time to diagnose infections
When a patient arrives at a hospital with a serious infection, doctors have precious few minutes to make an accurate diagnosis and prescribe treatment accordingly. A new diagnostic device created by a collaborative team of UA engineers and scientists may significantly reduce the amount of time necessary to diagnose tissue infections.

Beyond species counts: Using evolutionary history to inform conservation
With limited funding available, a common strategy for conservation planners is to identify areas of high species richness and endemicity, but this approach ignores evolutionary history and so may overlook important regions for conservation. A recent study, available in Applications in Plant Sciences, argues for the importance of incorporating phylogenetic diversity metrics in conservation planning. The study tests a dozen commonly used metrics so users can determine which metrics should be used in which situations.

Before nature selects, gene networks steer a course for evolution
Natural selection is a race to reproduce, a competition between individuals with varying traits that helps direct evolution. How do the structures of gene networks determine which individuals appear on the starting line, silently influencing evolution before competition has even begun? University of Illinois researchers Karen Sears and Zoi Rapti, along with collaborators at Illinois and four other institutions, have addressed this question by exploring the gene network that guides limb development in mammals.

Microscopic animals inspire innovative glass research
When Juan de Pablo and his collaborators set about to explain unusual peaks in what should have been featureless optical data, they thought there was a problem in their calculations. In fact, what they were seeing was real. The peaks were an indication of molecular order in a material thought to be entirely amorphous and random: their experiments had produced a new kind of glass.

In analyzing a scene, we make the easiest judgments first
Psychologists have hypothesized that when we try to understand the scenery we see, we begin by assessing some preordained priorities. A new study questions that idea by providing evidence that people simply make the easiest distinctions first.

Only above-water microbes play a role in cave development
Only the microbes located above the water's surface contribute to the development of hydrogen-sulfide-rich caves, suggests an international team of researchers. Since 2004, researchers have been studying the Frasassi cave system, an actively developing limestone cave system located 1500 feet underground in central Italy.

Radioactive contaminants found in coal ash
A Duke University-led study has found radioactive contaminants in coal ash from all three major US coal-producing basins. Levels of radioactivity in the ash were five to eight times higher than in normal soil or in the parent coal itself. This finding raises concerns about the environmental and human health risks posed by coal ash, which currently is unregulated and is stored in coal-fired power plants' holding ponds and landfills nationwide.

CT scan of Earth links deep mantle plumes with volcanic hotspots
Geophysicists have detected plumes of hot rock rising through the mantle from the core-mantle boundary, and hypothesized that they remain stationary for millions of years, generating volcanic island chains as the crust moves over them. UC Berkeley and Berkeley Lab scientists now have proof of this connection, after using seismic waves from large earthquakes to map Earth's interior to obtain a CT scan of the mantle. The plumes are much fatter than expected.

Fire in the Amazon
A six-year controlled burn experiment in the Amazon reveals a forest that is initially resilient to fires but vulnerable in the face of drought and repeated fire, which produced high tree mortality and encouraged grassland incursion. These effects could lead to greater fire severity and reduced carbon storage.
