If you're worried about finishing everything on your to-do list, you'll get an extra second today to cram it all in.

The extra second is called a "leap second." At the very end of the day, the clock will read 11:59:60 Universal Time (the official time that international timekeepers use) or 7:59:60 p.m. ET.

Patients often judge their doctors on their bedside manner.  But doctors also pay attention to how well they get along with their patients. But as Lake Effect essayist Dr. Bruce Campbell explains, it’s for reasons patients might not realize:

He is the happiest person in my medical practice, and every visit is full of his non-stop banter.  As soon as I walk in the room, he is off  and running.

Nothing says "I'm a new driver" more than a fire-red label stuck to your license plate for all to see. That's what happens in New Jersey to anyone with a learner's permit under age 21. But identifying these newest drivers doesn't necessarily help reduce crash rates, research finds.

The Internet is abuzz about the latest Easter egg found in Apple's Siri, as the virtual assistant gives a philosophical — and, to some, a personal — response to the question "What is zero divided by zero?"

Spotify, Google Play, Amazon Prime, Rdio, Rhapsody, Pandora — the list of streaming music service goes on and on. On Tuesday, Apple joins that lineup with the launch of its streaming service, Apple Music. Apple will give consumers a three-month trial, and then it will charge $9.99 a month.

The U.S. Supreme Court ruled Monday that the Environmental Protection Agency made a mistake when it told electric power plants to reduce mercury emissions. The high court says the EPA should first have considered how much it would cost power plants to do that.

The decision comes too late for most power companies, but it could affect future EPA regulations.

Mercury in the air is a health risk. When you burn coal or oil, you create airborne mercury that can end up in fish we eat and cause serious health problems.
