Michael Horn receives prestigious honor for young faculty
Northwestern University's Michael S. Horn, a scientist who studies how people learn from new technologies and designs innovative learning experiences, has received a prestigious Faculty Early Career Development (CAREER) Award from the National Science Foundation. Horn will design and study new computational literacy experiences for young people in museums, homes and out-of-school programs. A goal of his CAREER project, titled 'Blocks, Stickers and Puzzles: Rethinking Computational Literacy Experiences in Informal Environments,' is to increase diversity in postsecondary computer science programs.

Boosting nutrients gives a leg up to invasive species
Species invasions come at a high cost. In the United States, the annual cost to the economy tops $100 billion a year and invasive plant infestations affect 100 million acres. Basic questions remain about how and whether exotic species arefunctionally distinct from native species and why they tend to take over when introduced into new environments. A new study, led by University of Minnesota researcher Eric Seabloom, addresses that gap, drawing on data collected at 64 grassland sites in 13 countries.

Law governing anomalous heat conduction revealed
How heat travels, matters. Yet, there is still no consensus on the exact physical mechanism that causes anomalous heat conduction -- despite the existence of previous numerical simulation, theoretical predictions and experimental observations. Now, a team based in Asia has demonstrated that electron transport depends on temperature. It follows a scaling governed by a power law. These findings were recently published in EPJ B.

Ecologists predict impact of climate change on vulnerable species
As climate changes, many species are spreading beyond their historical ranges. Here biologists announce a method to predict which species decline as a result. Testing the method in Ontario, Canada, lakes where bass species have expanded northward with increasing temperatures, small fishes and fishes which rarely occurred with bass species were most likely to be lost where bass recently established. The method can predict losses due to competition and predation in a variety of organisms.

Nanowires highly 'anelastic,' research shows
At the nanoscale, familiar materials often take on unexpected properties. Researchers from Brown and NC State have shown that zinc oxide nanowires are highly anelastic, meaning they return to shape slowly after being bent, rather than snapping right back. Anelastic materials are good at dissipating of kinetic energy. This new finding suggest nanowires could be useful in absorbing shocks and vibrations.

Environmentally friendly lignin nanoparticle 'greens' silver nanobullet to battle bacteria
Researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.

Researchers find nanowires have unusually pronounced 'anelastic' properties
Researchers from North Carolina State University and Brown University have found that nanoscale wires (nanowires) made of common semiconductor materials have a pronounced anelasticity -- meaning that the wires, when bent, return slowly to their original shape rather than snapping back quickly.

How clouds get their brightness
How clouds form and how they help set the temperature of the earth are two of the big remaining questions in climate research. Now, a study of clouds over the world's remotest ocean shows that ocean life is responsible for up to half the cloud droplets that pop in and out of existence during summer.

Study finds surprisingly high geothermal heating beneath West Antarctic Ice Sheet
The amount of heat flowing toward the base of the West Antarctic ice sheet from geothermal sources deep within the Earth is surprisingly high, according to a new study led by UC Santa Cruz researchers. The results provide important data for researchers trying to predict the fate of the ice sheet, which has experienced rapid melting over the past decade.

A jump for soft-bodied robots
Wyss Institute researchers and their collaborators used a novel multi-material, 3-D printing strategy to construct entire robots using a layer upon layer approach to seamlessly blend rigid to soft components. The strategy permits construction of highly complex and robust structures that can't be achieved using conventional nuts and bolts manufacturing. A proof-of-concept prototype -- a soft-bodied autonomous jumping robot -- is reported in the July 10 issue of Science.

Where iron and water mix
A new study demonstrates that chemical-laden plumes erupted from vents at one section of Mid Ocean Ridge in the southeast Pacific can be traced all the way across the Pacific for more than 4,000 kilometers. It also shows how the iron can be brought to the surface oceans of Antarctica where it has the potential to serve as a key life-sustaining micronutrient, supporting removal of carbon from the sunlit upper waters of that ocean.

Global sea levels have risen 6 meters or more with just slight global warming
A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning is that amount of melting was caused by an increase of only 1-2 degrees (Celsius) in global mean temperatures.
