SEATTLE—How best to care for the many adolescents who have depression? In a collaborative care intervention, a care manager continually reached out to teens—delivering and following up on treatment in a primary-care setting (the office of a pediatrician or family doctor, not a psychiatrist or psychologist) at Group Health Cooperative. Depression outcomes after a year were significantly better with this approach than with usual care, according to a randomized controlled trial published in JAMA.

CAMBRIDGE, MA -- Researchers from MIT, Pennsylvania State University, and Carnegie Mellon University have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Their device, about the size of a dime, could be used to detect the extremely rare tumor cells that circulate in cancer patients' blood, helping doctors predict whether a tumor is going to spread.

(SACRAMENTO, Calif.) — Kit Lam and colleagues from UC Davis and other institutions have created dynamic nanoparticles (NPs) that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors. In addition, the particles are biocompatible and have shown no toxicity.

Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria account for some 80 percent of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.

PRINCETON, N.J.—Expanding the age of eligibility for measles vaccination from 12 to 15 months could have potentially large effects on coverage in Africa, according to a new report published by Princeton University's Woodrow Wilson School of Public and International Affairs.

If combined with improvements to the vaccination process itself, such a change could help the country inch closer to the national coverage levels required for measles eradication. The findings were published in Epidemiology & Infection.

At the stroke of a pen a New Zealand endemic tree has for the last 31 years been incorrectly regarded the same as a group of 'weedy' Australian shrubs and small trees. A New Zealand botanist has completed a 15-year study to reveal some surprises and discover astonishing cryptic diversity behind what was long considered a single tree species. The study was published in the open access journal PhytoKeys.

ROSEMONT, Ill.—Each year, more than 300,000 Americans, primarily adults over age 65, sustain a hip fracture, a debilitating injury that can diminish life quality and expectancy, and result in lost work days and substantial, long-term financial costs to patients, families, insurers and government agencies. And while surgery, the primary treatment for hip fractures, successfully reduces mortality risk and improves physical function, little is known about the procedure's value and return on investment.

The Ames test, a widely used method to determine whether a chemical has the potential to cause cancer, has been successfully adapted for use with cigarette smoke and other complex aerosols.

New Haven, Conn. – New national guidelines can improve the way statin drugs are prescribed to patients at risk for cardiovascular disease, a Yale University study has found.

The research, published Aug. 25 in the Journal of the American College of Cardiology, also showed the new guidelines produce only a modest increase in the number of patients being given the drugs.

A study from the University of Liverpool has recommended investing in dog owner education and facilities as a strategy to target physical inactivity and problems such as obesity in both people and their pets.

In a review of scientific papers published since 1990, the researchers found that access to dog-friendly walking environments and better education about dogs' physical needs, could all motivate people to get out and take more exercise with their pets.

Ask any parent raising kids in today's fast-paced society and chances are they would agree that there are only so many hours in the day. Recognizing a need for help, many businesses now offer traditional caregiving services ranging from planning birthday parties to teaching children how to ride a bike. According to a new study in the Journal of Consumer Research, by outsourcing traditional parental duties, modern-day parents feel they are ultimately protecting parenthood.

Are environmental and social problems such as global warming and poverty the result of inadequate governmental regulations or does the burden fall on our failure as consumers to make better consumption choices? According to a new study in the Journal of Consumer Research, responsible consumption shifts the burden for solving global problems from governments to consumers and ultimately benefits corporations more than society.

Do you feel sadder watching a documentary about war or a drama about a young person dying of cancer? According to a new study in the Journal of Consumer Research, consumers mistakenly believe they will have stronger emotional reactions when stories are based on true events rather than fiction.
