Berkeley Lab scientists develop new method for evaluating short-lived pollutants.

New research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found that levels of methane—a potent greenhouse gas emitted from many man-made sources, such as coal mines, landfills and livestock ranches—are at least one-and-a-half times higher in California than previously estimated.

Working with scientists from the National Oceanic and Atmospheric Administration (NOAA) Berkeley Lab scientists Marc L. Fischer and Seongeun Jeong combined highly accurate methane measurements from a tower with model predictions of expected methane signals to revise estimated methane emissions from central California. They found that annually averaged methane emissions in California were 1.5 to 1.8 times greater than previous estimates, depending on the spatial distribution of the methane emissions. (more…)

Sexual Orientation Fluctuation Correlated to Alcohol Misuse, MU Researcher Finds

Understanding this phenomenon could improve psychological support systems for sexual minorities and help young people avoid alcohol problems.

COLUMBIA, Mo. — Many young adults explore and define their sexual identity in college, but that process can be stressful and lead to risky behaviors. In a new study, students whose sexual self-definition didn’t fall into exclusively heterosexual or homosexual categories tended to misuse alcohol more frequently than people who had a firmly defined sexual orientation for a particular gender, according to University of Missouri researchers. These findings could be used to improve support programs for sexual minorities.

“Bisexuals and students whose sexual orientation was in flux reported the heaviest drinking and most negative consequences from alcohol use, such as uncontrolled drinking and withdrawal symptoms,” said Amelia Talley, MU assistant professor of psychological sciences in the College of Arts and Science. “Those groups reported drinking to relieve anxiety and depression at higher rates than strictly heterosexual or homosexual individuals. One possible explanation is that people who aren’t either completely heterosexual or homosexual may feel stigmatized by both groups.” (more…)

Ancient Story of Dartmoor Tors Has an Ice-Cold Twist

Ice extended further across the UK than previously thought and played a part in sculpting the rocky landscape of Dartmoor in South West England during the last Ice Age, according to new research which challenges previously held theories.

A study of the National Park area of Dartmoor, UK, shows for the first time that an ice cap and valley glaciers were present in its centre and that the naturally castellated stone outcrops, known as tors, were survivors.

The new research by the Universities of Durham and Exeter, and Stockton Riverside College, is published in the journal Quaternary Science Reviews.

Researchers, who carried out detailed observations on the ground and using aerial photography, say the evidence includes glacial features such as elongated rounded mounds or drumlins and hummocky landforms or moraines. Similar features may also exist in other upland areas of southwest England, indicating that small upland glaciers were regularly hosted in the region during periods of glaciation. (more…)

How to Effectively Compare Auto Insurance Quotes

As the economy of the world continues to fluctuate and the unemployment rates remain high even in the most stable first world economies, people everywhere are looking for ways to cut back their monthly budgets. One of the first things that is usually on the chopping block are the various insurance packages that people consider a luxury.

Although this is perhaps the least advisable way to lower monthly liabilities, many people think that it is their only option. They believe that prices on things like car insurance and home insurance are set in stone, and that they cannot be negotiated down. This notion is far from the truth. (more…)

UD’s Schmidt studies genome of crocodile family in evolution research

University of Delaware scientist Carl Schmidt is working to identify genes in crocodiles, alligators and gharials as he searches for links between the creatures that could give clues as to how they evolved over the years in relation to one another.

Schmidt’s effort is part of a National Science Foundation-funded project being conducted by a team of researchers assembled by David Ray, an evolutionary biologist at Mississippi State University. (more…)

Mobile devices not replacing printed newspapers as quickly as earlier predicted, MU expert says

COLUMBIA, Mo. — Two-thirds of U.S. adults now use at least one mobile media device in their daily lives, according to a national survey recently conducted by the Reynolds Journalism Institute (RJI) at the University of Missouri School of Journalism. The RJI survey found that news consumption ranks fourth among reasons people use mobile devices, behind interpersonal communications, entertainment, and Internet usage for information not provided by news organizations. Despite the large number of mobile device users, Roger Fidler, the program director for digital publishing at RJI, says that mobile news products do not appear to be replacing printed newspapers as quickly as was earlier predicted.

One of the largest and longest studies in a traditional African society sheds light on religious practices and cuckoldry. Genetic data suggest religious patriarchy is directly analogous to the mate-guarding tactics used by animals to ensure paternity.

Religious practices that strongly control female sexuality are more successful at promoting certainty about paternity, according to a study published in the June 4, 2012 issue of the Proceedings of the National Academy of Sciences.

In an interdisciplinary collaboration, a group of researchers around biological anthropologist Beverly Strassmann from the University of Michigan and University of Arizona geneticist Michael Hammer analyzed genetic data on 1,706 father-son pairs in a traditional African population – the Dogon people of Mali, West Africa – in which Islam, two types of Christianity and an indigenous, monotheistic religion are practiced in the same families and villages.
