The Washington Post (12/24, Ingraham) “Wonkblog” reported that according to data from the Centers for Disease Control and Prevention, “the risk of being killed by another person is lowest in New England and the upper Midwest, and highest in the deep South, particularly Mississippi and Louisiana.” The Post pointed out that Louisiana’s age-adjusted homicide rate of 11.67 per 100,000 people and Mississippi is a close second, at 11.41.

The Post also explained that the District of Columbia’s homicide rate is 13.67 deaths per 100,000 but that “comparing it to the more geographically diverse states isn’t very meaningful.” The Post wrote that “the homicide rate in Louisiana is a whopping nine times higher than the rate in New Hampshire, the state with the lowest homicide rate.”

The Telegraph (UK) (12/27, Donnelly) reported that “a major study” conducted by University College London researchers suggests that youngsters “brought up by single parents and in step families are three times as likely to suffer from mental health problems.” The study, which included some “10,000 children, found that those brought up by both natural parents are far less likely to suffer severe emotional and behavioural problems.”

ABC World News (12/22, story 13, 0:25, Muir) reported that the NFL is “under fire” for “withholding $16 million from researchers investigating football-related head trauma.” The NFL was funding the study, which is being conducted by the National Institutes of Health, but the league was “reportedly critical of the doctor leading the project.” NFL officials are “disputing the report.”

The Washington Post (12/23, Larimer) reports on the ESPN “Outside the Lines” story, which claimed that the NFL “‘backed out’ of the planned seven-year, $16 million research project to attempt to diagnose chronic traumatic encephalopathy (CTE) in living patients.” The study was originally “to have been paid for by a $30 million grant from the NFL made to the National Institutes of Health in 2012.” However, “the NIH will fund the study itself, according to a Tuesday morning news release.”

The New York Times (12/23, B9, Belson, Subscription Publication) reports that the National Institutes of Health and the National Institute of Neurological Disorders and Stroke awarded the grant “as part of a long-term study of brain disease in former NFL and college football players, many of whom sustained multiple concussions on the field,” but the NFL “did not help pay for the grant.”
