There's a rich body of evidence that links chocolate to heart health.

Now comes a new study that finds people who consume small amounts of chocolate each week have a lower risk of developing atrial fibrillation, a heart condition characterized by a rapid or irregular heartbeat.

Last year's Zika outbreak in Miami likely started in the spring of 2016, with the virus introduced multiple times before it was detected, researchers say. And most of those cases originated in the Caribbean.

Sleek, high-tech wristbands are extremely popular these days, promising to measure heart rate, steps taken during the day, sleep, calories burned and even stress.

The year was 1945, and 2-year-old Lindy Thomson had been given a few weeks to live. She suffered from diarrhea and projectile vomiting, and she was so thin and weak, she could no longer walk. Her parents had taken her from doctor to doctor. Finally, Dr. Douglas Arnold in Buffalo, N.Y., offered a most unusual prescription: She was to eat bananas.

"At least seven bananas a day," recalls the patient, who now goes by her married name, Lindy Redmond.
