Metals used in high-tech products face future supply risks
Yale researchers have assessed the 'criticality' of all 62 metals on the Periodic Table of Elements, providing key insights into which materials might become more difficult to find in the coming decades, which ones will exact the highest environmental costs -- and which ones simply cannot be replaced as components of vital technologies.

Nanoscale worms provide new route to nano-necklace structures
Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.

Honey bees use multiple genetic pathways to fight infections
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers at Penn State and the Georgia Institute of Technology. The findings may help scientists develop honey bee treatments that are tailored to specific types of infections.

Fluctuation X-ray scattering
In biology, materials science and the energy sciences, structural information provides important insights into the understanding of matter. The link between a structure and its properties can suggest new avenues for designed improvements of synthetic materials or provide new fundamental insights in biology and medicine at the molecular level.

Sci-Fly study explores how lifeforms know to be the right size
Shakespeare said 'to be or not to be' is the question, and now scientists are asking how life forms grow to be the correct size with proportional body parts. Probing deeply into genetics and biology at the earliest moments of embryonic development, researchers at Cincinnati Children's Hospital Medical Center report March 26 in Nature Communications they have found new clues to explain one of nature's biggest mysteries.

Galaxy clusters collide; dark matter still a mystery
When galaxy clusters collide, their dark matters pass through each other, with very little interaction. Deepening the mystery, a study by scientists at EPFL and the University of Edinburgh challenges the idea that dark matter is composed of particles.

Swirling currents deliver phytoplankton carbon to ocean depths
Just as crocus and daffodil blossoms signal renewal and the start of a warmer season on land, a similar 'greening' event -- a massive phytoplankton bloom -- unfolds each spring in the Atlantic Ocean from Bermuda to the Arctic. But, what happens to all that organic material produced in the surface ocean?

Coastal property values could erode if nourishment subsidies end
The value of many oceanfront properties on the East Coast could drop dramatically if Congress were to suddenly end federal beach nourishment subsidies. Values could fall by as much as 17 percent in towns with high property values and almost 34 percent in towns with low property values. A gradual reduction of the subsidies, in contrast, is more likely to smooth the transition to more climate-resilient coastal communities.

Supermassive black hole clears star-making gas from galaxy’s core
A new study in the journal Nature, published March 26, 2015, provides the first observational evidence that a supermassive black hole at the center of a large galaxy can power huge, wide-angled outpourings of material from deep inside the galaxy's core. These outflows remove massive quantities of star-making gas, thus influencing the size, shape and overall fate of the host galaxy.

More schools, more challenging assignments add up to higher IQ scores
More schooling -- and the more mentally challenging problems tackled in those schools -- may be the best explanation for the dramatic rise in IQ scores during the past century, often referred to as the Flynn Effect, according to a team of researchers. These findings also suggest that environment may have a stronger influence on intelligence than many genetic determinists once thought.

Global water use may outstrip supply by mid-century
Population growth could cause demand for water to outpace supply by mid-century if current use levels continue. But it wouldn't be the first time this has happened, a Duke study finds. Using a mathematical model to analyze historic data, the researchers identified a regularly recurring pattern of time periods when demand for water outstripped supply, and shortages were resolved by technological advancements. The model projects a similar period of innovation could occur in coming decades.
