If your father and grandfather waited until they were older before having children, you might experience life-extending benefits. Biologists assume that a slow pace of aging requires that the body invest more resources in repairing cells and tissues. (more…)
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…)
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…)
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. (more…)
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…)
EAST LANSING, Mich. — In a society where people text rather than talk and eat out more than cook, community has been lost and necessities replaced by wants, says a group of Michigan State University students who recently released a documentary of their monthlong experiment in living with less.

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.
