FRIDAY, Jan. 19, 2018 -- Increasing the number of trees in extremely large cities can lead to significant health and financial benefits, a new study claims.
The researchers focused on 10 so-called mega-cities -- those with at least 10 million people -- on five continents. They included New York City, London and Mexico City. Nearly 10 percent of the world's population live in mega-cities.
FRIDAY, Jan. 19, 2018 -- A group of former National Football League greats -- including Hall of Famers Harry Carson of the New York Giants and Nick Buoniconti of the Miami Dolphins -- is urging parents not to let their children play tackle football until they're at least 14 years old.
The group is instead endorsing a program called "Flag Football Under 14," launched by the Concussion Legacy Foundation. The program aims to educate parents and young players about chronic traumatic encephalopathy. Sometimes called CTE, it is a degenerative brain disease caused by repeated blows to the head, and has been detected in more than 85 percent of tackle football players studied over the past 10 years, according to the foundation.
FRIDAY, Jan. 19, 2018 -- A pill-sized device that you swallow might help detect a change in the esophagus that can lead to a deadly form of cancer, researchers are reporting.
The esophagus is the tube that carries food from your mouth to your stomach. And the change that occurs in the esophagus, known as Barrett's esophagus, usually results from long-term reflux. Barrett's esophagus is considered a precursor to a type of cancer called esophageal adenocarcinoma.
