Do drinking and marriage mix? That depends on who’s doing the drinking — and how much — according to a recent study by the University at Buffalo Research Institute on Addictions (RIA).
A new report by the Substance Abuse and Mental Health Services Administration (SAMHSA) shows that people aged 12 to 49 who had used prescription pain relievers nonmedically were 19 times more likely to have initiated heroin use recently (within the past 12 months of being interviewed) than others in that age group (0.39 percent versus 0.02 percent). The report also shows that four out of five recent heroin initiates (79.5 percent) had previously used prescription pain relievers nonmedically.
Vedolizumab, a new intravenous antibody medication, has shown positive results for treating both Crohn’s disease and ulcerative colitis, according to researchers at the University of California San Diego, School of Medicine. The findings, published in two papers, will appear in the August 22 issue of the New England Journal of Medicine (NEJM).
New research suggests that chronic traumatic encephalopathy (CTE), a brain disease associated with repeat brain trauma including concussions in athletes, may affect people in two major ways: initially affecting behavior or mood or initially affecting memory and thinking abilities. The study appears in the August 21, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. CTE has been found in amateur and professional athletes, members of the military and others who experienced repeated head injuries, including concussions and subconcussive trauma.
Part of the risk for alcohol dependence is genetic. The same is true for eating disorders. Now researchers at Washington University School of Medicine in St. Louis have found that some of the same genes likely are involved in both. They report that people with alcohol dependence may be more genetically susceptible to certain types of eating disorders and vice versa.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered starburst galaxies earlier in the Universe’s history than they were previously thought to have existed. These newly discovered galaxies represent what today's most massive galaxies looked like in their energetic, star-forming youth.
South Pole Telescope observations have led to the discovery that dust-filled galaxies were bursting with stars much earlier in cosmic history than previously thought.

UCLA researchers have found a link between Parkinson's disease and the pesticide Benomyl, whose toxicological effects still linger in the environment, ten years after it was banned by the EPA. More important, the research suggests the way this pesticide does its damage may occur in other people with Parkinson's, even for those who were not exposed to this pesticide.
Researchers at UCLA say it's not just what you eat that makes those pants tighter — it's also genetics. In a new study, scientists discovered that body-fat responses to a typical fast-food diet are determined in large part by genetic factors, and they have identified several genes they say may control those responses.
The Annual Report to the Nation on the Status of Cancer, 1975–2009, shows that overall cancer death rates continued to decline in the United States among both men and women, among all major racial and ethnic groups, and for all of the most common cancer sites, including lung, colon and rectum, female breast, and prostate. However, the report also shows that death rates continued to increase during the latest time period (2000 through 2009) for melanoma of the skin (among men only) and for cancers of the liver, pancreas, and uterus. The special feature section on human papillomavirus (HPV)-associated cancers shows that incidence rates are increasing for HPV-associated oropharyngeal and anal cancers and that vaccination coverage levels in the U.S. during 2008 and 2010 remained low among adolescent girls.
