Cape Cod saltmarsh recovery looks good, falls short
In some places Cape Cod's imperiled saltmarsh grasses have been making a comeback, but a new study reports that their ability to protect the coast has not returned nearly as fast as their healthy appearance would suggest.

Chimpanzee lethal aggression a result of adaptation rather than human impacts
A new study using long-term data gathered on chimpanzee aggression is the first effort to test the human impact versus adaptive strategies hypothesis and finds that human impact is not the culprit.

Smallest known galaxy with a supermassive black hole
A University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole -- the smallest galaxy known to contain such a massive light-sucking object. The finding suggests huge black holes may be more common than previously believed.

Novel capability enables first test of real turbine engine conditions
Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between the US Department of Energy's Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.

For electronics beyond silicon, a new contender emerges
Using a quantum material called a correlated oxide, Harvard researchers have achieved a reversible change in electrical resistance of eight orders of magnitude, a result the researchers are calling 'colossal.' In short, they have engineered this material to perform comparably with the best silicon switches.

Scientists create therapy-grade stem cells using new cocktail to reprogram adult cells
Researchers at the Hebrew University of Jerusalem have developed a new cocktail that coaxes adult cells to become pluripotent stem cells of a high enough quality to be used in therapeutic applications. Their research showed that using a different combination of reprogramming factors can produce a much higher quality result, delivering fewer colonies of iPSCs of which 80 percent passed the toughest pluripotency test.

Judging a fish by its color: For female bluefin killifish, love is a yellow mate
Researchers used male replicas of bluefin killifish and controlled their movement with robotic arms to improve repeatability in experiments designed to determine how fertile female fish would respond to male courtship. The surprising result: The females preferred males with yellow fins, contrary to existing research that indicated a preference to blue and red.

Meteorite that doomed dinosaurs remade forests
The impact decimated slow-growing evergreens and made way for fast-growing, deciduous plants, according to a study applying biomechanical analyses to fossilized leaves. The study provides much-needed evidence for how the extinction event unfolded in the plant communities at the time.

Northeastern University researchers develop novel method for working with nanotubes
Northeastern University researchers have developed a novel method for controllably constructing precise inter-nanotube junctions and a variety of nanocarbon structures in carbon nanotube arrays. The researchers were able to tailor the physical properties of nanotube networks for use in applications from electronic devices to carbon nanotube-reinforced composite materials found in cars and sports equipment. The findings were published in a Nature Communications paper titled 'Sculpting carbon bonds for allotropic transformation through solid-state re-engineering of –sp2 carbon.'

Long-term effects of childhood asthma influenced by socioeconomic status
Studies have shown that asthma is associated with attention and behavioral issues in children, yet little existing research examines how socioeconomic status may influence the ultimate effects of these difficulties. Now, a University of Missouri researcher has found that the overall outcomes for children with asthma are influenced by socioeconomic inequalities.

Tigers, pandas and people a recipe for conservation insight
The first big revelation in conservation sciences was that studying the people on the scene as well as nature conservation was crucial. Now, as this science matures, researchers are showing that it's useful to compare apples and oranges. Or, more accurately, tigers and pandas. In this week's journal Ecology & Society, Michigan State University scientists show that useful insights and ways of scrutinizing wildlife and their habitat can be found in unlikely places.

Cancer and the immune system: A double-edged sword
During cancer development, tumor cells decorate their surfaces with sugar compounds called glycans that are different from those found on normal, healthy cells. Researchers at the University of California, San Diego School of Medicine report that sialic acids at the tips of these cancer cell glycans are capable of engaging with immune system cells and changing the latter's response to the tumor -- for good and bad.

Contaminated water in 2 states linked to faulty shale gas wells
Faulty well integrity, not hydraulic fracturing deep underground, is the primary cause of drinking water contamination from shale gas extraction in parts of Pennsylvania and Texas, according to a study by researchers from five universities. The study, which is the first to document methane contamination occurring in previously unaffected water wells, used both hydrocarbon and noble gas tracers to track the contamination back to leaks in gas well casings and cementing.

Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.
