Recreational Fishing Brings Salt Marsh Die-Off

As recreational fishing activity has reduced predators in many of Cape Cod’s salt marsh ecosystems, Sesarma crabs have feasted on grasses, causing dramatic die-offs of the marshes, according to a new study. The researchers assessed the “trophic cascade” in several experiments that also ruled out alternative explanations for the problem.

PROVIDENCE, R.I. [Brown University] — Recreational fishing is a major contributor to the rapid decline of important salt marshes along Cape Cod because it strips top predators such as striped bass, blue crabs, and smooth dogfish out of the ecosystem, according to new research by Brown University ecologists.

Learning About Spatial Relationships Boosts Understanding of Numbers

Science

Children who are skilled in understanding how shapes fit together to make recognizable objects also have an advantage when it comes to learning the number line and solving math problems, research at the University of Chicago shows.

The work is further evidence of the value of providing young children with early opportunities in spatial learning, which contributes to their ability to mentally manipulate objects and understand spatial relationships, which are important in a wide range of tasks, including reading maps and graphs and understanding diagrams showing how to put things together. Those skills also have been shown to be important in the Science, Technology, Engineering and Mathematics (STEM) fields. (more…)

“Extremely Little” Telescope Discovers Pair of Odd Planets

ANCHORAGE, Alaska – Even small telescopes can make big discoveries.

Though the KELT North telescope in southern Arizona carries a lens no more powerful than a high-end digital camera, it’s just revealed the existence of two very unusual faraway planets. (more…)

Teaching Autistic Teens to Cope

Health

Unique UCLA program that teaches social skills proves effective over long term

Teenagers with autism spectrum disorder are in a bind. The disorder is characterized by impairments in communication and social interaction, but it’s a continuum, so some teens diagnosed with ASD are considered high functioning and healthy enough to be “mainstreamed” in school.

But without the proper social skills, even mainstreamed teens don’t quite fit into the general social milieu of middle school or high school. As a result, they suffer from all the slings and arrows of that world.

Since 2006, however, the UCLA PEERS (Program for the Education and Enrichment of Relational Skills) clinic has assisted high-functioning teens with ASD by literally teaching them the strategies they need to fit in better with their peers. And while previous research demonstrated that the program was effective, it wasn’t known whether the new skills “stuck” with these teens after they completed the PEERS classes. (more…)

Offspring of Older Fathers May Live Longer

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…)

Measuring the “Other” Greenhouse Gases: Higher Than Expected Levels of Methane in California

Environment

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

Culture, Health

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…)
