Earthquakes in western Solomon Islands have long history, study shows
Researchers have found that parts of the western Solomon Islands, a region thought to be free of large earthquakes until an 8.1 magnitude quake devastated the area in 2007, have a long history of big seismic events. The team, led by researchers at The University of Texas Austin, analyzed corals for the study.

New study reveals mechanism regulating methane emissions in freshwater wetlands
Though they occupy a small fraction of the Earth's surface, freshwater wetlands are the largest natural source of methane going into the atmosphere. New research from the University of Georgia identifies an unexpected process that acts as a key gatekeeper regulating methane emissions from these freshwater environments. The study, published in Nature Communications by Samantha Joye and colleagues, describes how high rates of anaerobic methane oxidation substantially reduce atmospheric emissions of methane from freshwater wetlands.

Where the wild things aren't: Cats avoid places coyotes roam
Caught in the act: millions of images from citizen scientists show that free-ranging domestic cats do their hunting close to home in neighborhoods and small urban forests, avoiding areas with coyotes.

OU student use nation's weather radar network to track bird migration at night
Using the nation's weather radar network, two University of Oklahoma doctoral students have developed a technique for forecasting something other than the weather: the orientation behavior of birds as they migrate through the atmosphere at night. The students have discovered a way to use the latest dual-polarization radar upgrade to measure broad-scale flight orientation of nocturnal migrant birds -- a promising development for biologists and bird enthusiasts.

Stuck on you: Research shows fingerprint accuracy stays the same over time
Fingerprints have been used by law enforcement and forensics experts to successfully identify people for more than 100 years. Though fingerprints are assumed to be infallible personal identifiers, there has been little scientific research to prove this claim to be true. As such, there have been repeated challenges to the admissibility of fingerprint evidence in courts of law.

OU professor developing vaccine to protect global communities from malaria
An OU professor studying malaria mosquito interaction has discovered a new mosquito protein for the development of a vaccine that is expected to stop the spread of the disease in areas where it is considered endemic. Malaria is transmitted by mosquitoes, and it infects millions of people in Africa, Asia and South America every year, causing a global health crisis. Local populations, US military personnel stationed in these areas and travelers to these malaria-prone areas are at risk of becoming infected.

Atmospheric mysteries unraveling
It's been difficult to explain patterns of toxic mercury in some parts of the world, such as why there's so much of the toxin deposited into ecosystems from the air in the southeastern United States, even upwind of usual sources. Now, a new analysis led by researchers at the University of Colorado Boulder shows that one key to understanding mercury's strange behavior may be the unexpected reactivity of naturally occurring halogen compounds from the ocean.

Recent mercury pollution on the rise, but quick to change, Dartmouth-led study shows
A Dartmouth-led study using a 600-year-old ice core shows that global mercury pollution increased dramatically during the 20th century, but that mercury concentrations in the atmosphere decreased faster than previously thought beginning in the late 1970s when emissions started to decline.

Food for thought: Use more forages in livestock farming
Small-scale livestock farming in the tropics can become more intensive yet sustainable if more and better forage is used to feed the animals being reared. This could benefit farming endeavors in rural South Asia, sub-Saharan Africa, Central America and the Caribbean, and see a move away from the increased reliance on grain-based feeds, say scientists at CIAT (International Center for Tropical Agriculture) and Thomas Rudel of Rutgers University in the US, in Springer's journal Ambio.

Researchers discover how petunias know when to smell good
A team of UW biologists has identified a key mechanism plants use to decide when to release their floral scents to attract pollinators. Their findings, published the week of June 29 in the Proceedings of the National Academy of Sciences, connect the production and release of these fragrant chemicals to the innate circadian rhythms that pulse through all life on Earth.

Exercising early in life yields rewards in adult years
What impact can exercise done early in life have on the propensity for exercising during the adult years? Researchers at the University of California, Riverside did experiments on mice in the lab to find out. They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass -- results that may have relevance for the public policy debates concerning the importance of physical education for children.

Some forestlands cool climate better without trees, Dartmouth-led study finds
Forests worldwide are increasingly used to store carbon as a way to slow climate change, but a Dartmouth-led study finds that some wooded areas may be more valuable without trees, allowing the cleared landscape to reflect rather than absorb the sun's energy. In other words, it's better to have snow-covered ground act as a natural mirror if you want to use some forest lands to cool the climate.

Giving atoms their marching orders
Building self-assembled 'molecular straws' from bis-urea macrocycles, Linda Shimizu of the University of South Carolina has developed a new nanotube system that can be used to directly compare single-file diffusion dynamics with Fickian diffusion dynamics. She and co-author Russ Bowers of the University of Florida use hyperpolarized xenon-129 NMR to study gas transport dynamics in two highly homogeneous nanotubes, one with a narrow-bore, hollow interior that can accommodate xenon gas atoms only in single file.

Stem cell injections improve diabetic neuropathy in animal models
Rats modeled with diabetic neuropathy were randomly assigned to BM-MSC or saline injection 12 weeks after diabetes modeling to investigate whether local transplantation could attenuate or reverse experimental DN. The study provided the first evidence that intramuscular injected BM-MSCs migrated to nerves and increased angiogenic and neurotrophic factors associated with blood vessel growth, aiding the survival of nerves. Results suggested that BM-MSC transplantation restored both the myelin sheath and nerve cells in sciatic nerves.
