When my husband has a particularly tough workout (or workday), he comes home and says, "I have to roll."

He's talking about using a foam roller on body parts including the hips, quads and calves, using his own body weight to supply the force.

The Federal Aviation Administration is proposing to fine a Chicago-based drone operator $1.9 million for repeatedly violating FAA regulations and flying in restricted airspace.

Senior citizens are switching from privately run insurance plans to traditional Medicare when they face serious, long-term health conditions, a study shows.

Researchers at Brown University found that 17 percent of Medicare Advantage patients who entered nursing homes for long-term care chose to switch to traditional Medicare the following year. Only 3 percent of similar patients in Medicare made the decision to go to a private Medicare Advantage plan.

Two scientists from Canada and Japan have won the 2015 Nobel Prize in Physics 2015 for opening "a new realm in particle physics," the Nobel Prize committee says. Working far apart, both Takaaki Kajita and Arthur B. McDonald showed how neutrinos shift identities like chameleons in space.
