Boys with attention deficit hyperactivity disorder (ADHD) may be at risk for obesity later in life, according to a new study — which, if confirmed in larger studies, may have implications for more than 4 million kids in the United States living with the disorder.

Researchers at NYU’s Langone Medical Center have been following more than 200 kids for four decades. They found those who had ADHD in their early years were twice as likely to be obese at age 41.

A new virus in the same family as SARS — found for the first time in humans in recent months — has infected 40 people, most of them in the Middle East.

Half of those infected have died, according to the World Health Organization (WHO). Earlier this week, the WHO reported two health care workers in Saudi Arabia had been sickened while treating patients.

Cases of the virus, called the novel coronavirus or nCoV, have also been reported in European countries, most recently France but also Germany and the United Kingdom.
