Tiny Amounts of Alcohol Dramatically Extend A Worm’s Life, But Why?

Minuscule amounts of ethanol, the type of alcohol found in alcoholic beverages, can more than double the life span of a tiny worm known as Caenorhabditis elegans, which is used frequently as a model in aging studies, UCLA biochemists report. The scientists said they find their discovery difficult to explain.

“This finding floored us — it’s shocking,” said Steven Clarke, a UCLA professor of chemistry and biochemistry and the senior author of the study, published Jan. 18 in the online journal PLoS ONE, a publication of the Public Library of Science. (more…)

Marijuana Use Continues to Rise Among U.S. Teens, While Alcohol Use Hits Historic Lows

ANN ARBOR, Mich.— Among the more important findings from this year’s Monitoring the Future survey of U.S. secondary school students are the following:

Marijuana use among teens rose in 2011 for the fourth straight year—a sharp contrast to the considerable decline that had occurred in the preceding decade. Daily marijuana use is now at a 30-year peak level among high school seniors.
“Synthetic marijuana,” which until earlier this year was legally sold and goes by such names as “K2” and “spice,” was added to the study’s coverage in 2011; one in every nine high school seniors (11.4%) reported using that drug in the prior 12 months.
Alcohol use—and, importantly, occasions of heavy drinking—continued a long-term gradual decline among teens, reaching historically low levels in 2011.
Energy drinks are being consumed by about one third of teens, with use highest among younger teens. (more…)

Smokers with Mental Disorders, Drug and Alcohol Problems Need Doctors’ Help to Quit

Smokers who also have alcohol, drug and mental disorders would benefit greatly from smoking-cessation counseling from their primary care physicians and would be five times more successful at kicking the habit, a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center has found.

Smokers with these co-morbid conditions make up about 40 percent of the smoking population, have a more difficult time quitting and represent a significant burden on the health care system. If their primary care physicians could help them to quit smoking, it would not only improve their health of patients but would reduce tobacco-related health care costs, said Dr. Michael Ong, an assistant professor of general internal medicine and health services research at the David Geffen School of Medicine at UCLA and a researcher with UCLA’s Jonsson Comprehensive Cancer Center.

Study Finds Public Relatively Unconcerned About Nanotechnology Risks

A new study finds that the general public thinks getting a suntan poses a greater public health risk than nanotechnology or other nanoparticle applications. The study, from North Carolina State University, compared survey respondents’ perceived risk of nanoparticles with 23 other public-health risks.

The study is the first to compare the public’s perception of the risks associated with nanoparticles to other environmental and health safety risks. Researchers found that nanoparticles are perceived as being a relatively low risk. (more…)

For Longer-Life, Disease-Free Roses, NC State Researchers Insert Celery Gene

A rose by any other name would smell … like celery?

North Carolina State University research intended to extend the “vase life” of roses inserts a gene from celery inside rose plants to help fight off botrytis, or petal blight, one of the rose’s major post-harvest diseases.

Some fungal pathogens, the bad guys that infect plants, produce a sugar alcohol called mannitol that interferes with the plant’s ability to block disease like petal blight, which produces wilty, mushy petals – an effect similar to what happens to lettuce when it’s been in the crisper too long.

*Researchers Recommend Public and Private Action*

COLLEGE PARK, Md. – Highly-caffeinated energy drinks – even those containing no alcohol – may pose a significant threat to individuals and public health, say researchers at the University of Maryland School of Public Health and Wake Forest University School of Medicine.

In a new online commentary in the Journal of the American Medical Association (JAMA), they recommend immediate consumer action, education by health providers, voluntary disclosures by manufacturers and new federal labeling requirements. (more…)

Marijuana Use is Rising; Ecstasy Use is Beginning to Rise; and Alcohol Use is Declining Among U.S. Teens

ANN ARBOR, Mich.— Several important findings come out of this year’s Monitoring the Future study, the 36th annual, national survey of American teens in a series that launched in 1975.

• Marijuana use, which had been rising among teens for the past two years, continues to rise again this year—a sharp contrast to the considerable decline of the preceding decade.

• Ecstasy use—which fell out of favor in the early 2000s as concerns about its dangers grew—appears to be making a comeback this year, following a considerable recent decline in the belief that its use is dangerous.

• Alcohol use—and, specifically, occasions of heavy drinking—continues its long-term decline among teens into 2010, reaching historically low levels. (more…)
