Researchers continue to build on a body of evidence for a fragmented comet that is thought to have exploded over the Earth almost 13,000 years ago, which may have had a role in the disappearance of mammoths, mastodons and most of other megafauna at that time, and in the vanishing of the Clovis culture from the archaeological record in North America.

About The Study: This cohort study found an association of parental diseases of despair (defined as a suicide attempt, alcohol-related disease, or substance use disorder) with youth suicidal events; this finding may be underlying the increase in adolescent suicidal behavior observed in the U.S. over the past 2 decades. Improved access to care for parents with diseases of despair and systematic screening and referral of their offspring could help to reduce the adolescent suicide rate.

Parents of children with variable levels of walking impairment perceive significant quality of life improvements in their children after six months of living with a mobility assistance dog, according to the first qualitative assessment of its type that provides important evidence in an area of growing therapeutic interest.

Specifically, the parents of 10 children aged 6-12 with neurological and/or physical impairments in their walking perceived improvements in most of the childrens’ physical activity levels, as well as in their social engagement and family life.

A Rutgers study links participation in nonathletic clubs and volunteering in high school to higher levels of altruism later in life

Flavoured drinks without sugar can be perceived as sweet – and now researchers know why. A new study from Karolinska Institutet in Sweden, published in the journal Nature Communications, reveals that the brain interprets certain aromas as taste.

The accuracy of machine learning algorithms for predicting suicidal behavior is too low to be useful for screening or for prioritizing high-risk individuals for interventions, according to a new study published Sept. 11 in the open-access journal PLOS Medicine by Matthew Spittal of the University of Melbourne, Australia, and colleagues.
