Environmental toxins may be hurting North American eagles

2014-11-04
(Press-News.org) New research indicates that bald and golden eagles in North America may be exposed to dangerously high levels of polybrominated diphenyl ethers (PBDEs), which are chemicals used in the production of a wide variety of textiles, plastics, and electronics.

Investigators analyzed the livers of 33 bald eagles and 7 golden eagles collected throughout Washington and Idaho, finding that eagles associated with large urban areas had the highest PBDE concentrations.

"The PBDE concentrations we observed in eagle livers suggest a range of exposure, from nearly no detection to concentrations that may be significant toxicologically," wrote the-authors of the Environmental Toxicology study. "More information is required to evaluate trends in exposure and accumulation in eagles in the northwest United States and whether trends or source areas differ regionally across North America."

Up in smoke: Secondhand smoke can cause weight gain

Up in smoke: Secondhand smoke can cause weight gain
2014-11-04
New research is challenging the decades-old belief that smoking cigarettes helps keep you slim. A BYU study published in the American Journal of Physiology: Endocrinology and Metabolism finds that exposure to cigarette smoke can actually cause weight gain. But here's the kicker: Secondhand smoke is the biggest culprit. "For people who are in a home with a smoker, particularly children, the increased risk of cardiovascular or metabolic problems is massive," said author Benjamin Bikman, professor of physiology and developmental biology at Brigham Young University. Data ...

Drinking and poor academics affect the future of children with behavioral disorders

2014-11-04
Childhood behavioral conditions such as attention deficit hyperactivity disorder and conduct disorder are linked with an increased risk of being convicted of a felony later in life, with heavy drinking and educational failure contributing to this link. The findings, which come from an analysis of 4,644 men, suggest that substance use and educational disengagement in adolescence operate as stepping stones toward adult criminality among behaviorally disordered children. "We think the findings are important because they suggest potential avenues for preventing antisocial ...

NASA's Terra satellite sees Typhoon Nuri in eyewall replacement

NASAs Terra satellite sees Typhoon Nuri in eyewall replacement
2014-11-04
High clouds had moved over Super Typhoon Nuri's eye early on Nov. 4 when NASA's Terra satellite passed overhead as the storm was undergoing eyewall replacement. Eyewall replacement occurs when the thunderstorms that circle the eye of a powerful typhoons or hurricanes are replaced by other thunderstorms. Basically, a new eye begins to develop around the old eye. Many intense hurricanes undergo at least one of these eyewall replacements during their existence. On Nov. 4 at 01:55 UTC (8:55 p.m. EST) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument ...

Framework may help improve use of social media during disasters

2014-11-04
A new analysis illustrates the robust ways that social media can be employed to inform and improve disaster operations, and it provides a framework that could help standardize and organize disaster social media uses. Disaster social media users in the framework include communities, government, individuals, organizations, and media outlets. Fifteen distinct disaster social media uses were identified, ranging from providing and receiving disaster preparedness information to (re)connecting community members following a disaster. "Ultimately, emerging communication technologies ...

Parents' work schedules may impact family members' sleep

2014-11-04
In a recent US study of 1,815 disadvantaged mothers and their children, mothers who worked more than 35 hours per week were more likely to experience insufficient sleep compared with mothers who worked fewer hours, while children were more likely to experience insufficient sleep when their mothers worked between 20 and 40 hours. Nonstandard work schedules—such as working evenings, nights, or week-ends—were linked with an increased likelihood of insufficient sleep for mothers but not their children. "The results highlight a potentially difficult balance ...

To succeed in academia, grad students need 'street smarts'

2014-11-04
MAYWOOD, Il. – In an era of reduced funding, it's not enough for a young researcher to be a good scientist. He or she also needs "street smarts" to, for example, find an influential mentor, dress professionally, network during scientific meetings and be able to describe a research project in the time it takes to ride an elevator. These are among the techniques taught at a "Street Smarts for Science" workshop offered at the annual Society for Leukocyte Biology meeting, and described in the November issue of the journal Nature Immunology. What students learn in ...

Youth pastors feel ill-equipped to help youths with mental health issues, Baylor study finds

2014-11-04
Many mental health disorders first surface during adolescence, and college and youth pastors are in a good position to offer help or steer youths elsewhere to find it. But many of those pastors feel ill-prepared to recognize and treat mental illness, according to a Baylor University study. The study — "Adolescent mental health: the role of youth and college pastors" — is published in the journal Mental Health, Religion & Culture. Unlike senior pastors, those who work with young people are expected to have more extensive contact with their congregants because ...

TSRI study shows how exercise could reduce relapse during meth withdrawal

TSRI study shows how exercise could reduce relapse during meth withdrawal
2014-11-04
LA JOLLA, CA – November 3, 2014 – Scientists at The Scripps Research Institute (TSRI) have found that even brief workouts can reduce the risk of relapse in rats withdrawing from methamphetamine. In addition, the team found that exercise affected the neurons in a brain region that had never before been associated with meth withdrawal, suggesting a new direction for drug development. "There was no correlation between length of workout and risk of relapse—it's the mere involvement in the activity of physical fitness, rather than how much time you can put ...

Lactose intolerants at lower risk of certain cancers: Study

2014-11-04
People with lactose intolerance are at lower risk of suffering from lung, breast and ovarian cancers, according to a new study by researchers at Lund University and Region Skåne in Sweden. "We found that people with lactose intolerance, who typically consume low amounts of milk and other dairy products, have a reduced risk of lung, breast and ovarian cancers", says Jianguang Ji, Associate Professor at Lund University and researcher at the Center for Primary Care Research in Malmö. "The risk of cancer was not reduced in relatives of people with lactose intolerance, ...

Nature adores a hybrid
2014-11-04
This news release is available in French. Montreal, November 4, 2014 — Overfishing, climate change and pollution have reduced fish populations in Canadian lakes and rivers. While hatchery-raised fish could return numbers to normal, they aren't as well adapted to their new environments, and there's been concern that the wild population is "tainted" once it breeds with its domesticated counterparts. But new research from Concordia, published in the journal Evolutionary Applications, shows that after a few generations of breeding and natural selection, these ...
