Genetic mutations are the driving force of evolution, and now scientists have managed to study the effect of mutations in exquisite detail by watching what happens as they pop up in single cells.

Only about one percent of mutations were bad enough to kill off the cell, according to a report published Thursday in Science. Most of the time, these small changes in its DNA appeared to have no effect at all.

The Food and Drug Administration said Thursday it wants to sharply reduce the amount of nicotine in cigarettes. The idea is to help wean millions of smokers off their deadly habit and prevent millions more from becoming regular smokers in the first place.

Peter Sands took over this month as the new head of the Global Fund to Fight AIDS, Tuberculosis and Malaria. But before he'd even officially taken his seat at the Fund's offices in Geneva, he was under attack for a new partnership with Heineken.

We were hundreds of women, marching on the streets of Karachi, Pakistan.

We shouted slogans. '"Aurat aiee, aurat aiee, tharki teri shaamath aiee!" (Women are here, harassers must fear!)

We raised our fists in the air, smiling, laughing.

We wore what we wanted to wear: burqas, jeans and designer shades, brightly embroidered skirts, the traditional tunic and baggy trousers called shalwar kameez.

Men gaped, shook their heads, filmed us from passing cars as we walked by, disrupting traffic.

We did not care what the men thought of us.

As Alex Rivero biked around town raising money for the Newton North High School football team last fall, the 17-year-old started getting pretty good at guessing which houses were worth the door knock. He'd look for lights on and listen for kids' voices.

When he found a house that looked promising, he would stop.

At one place, Dr. Lee Goldstein opened the door. Goldstein cares a great deal about high school football. It's what he was thinking about when the doorbell rang.

A day after United Airlines faced a backlash over a dog's death in an overhead luggage compartment, the company is dealing with another canine-related mistake after a German shepherd meant for Kansas was instead flown to Japan.

People might not think of winter as a fruitful season for foraging wild edibles, but nutritionist and expert forager Debbie Naha says there's actually a lot out there that you can find year-round.

Elizabeth Holmes, the 34-year-old founder and CEO of the health technology company Theranos, had a compelling story of dropping out of college to launch a multibillion-dollar Silicon Valley venture to revolutionize the blood-testing industry.

The U.S. is one of only a few countries in the world that allow private individuals to own the minerals under their land, a policy that dates to the Founding Fathers as they sought to elevate private interests over those of the British Crown. This financial incentive to allow new drilling goes a long way in explaining the nation's natural gas boom. The National Association of Royalty Owners estimates some 12 million American landowners receive royalties for the exploitation of oil, gas and other mineral resources under their property.

How Many Opioid Overdoses Are Suicides?

Mady Ohlman was 22 on the evening some years ago when she stood in a friend's bathroom looking down at the sink.

"I had set up a bunch of needles filled with heroin because I wanted to just do them back-to-back-to-back," Ohlman recalls. She doesn't remember how many she injected before collapsing, or how long she lay drugged-out on the floor.

"But I remember being pissed because I could still get up, you know?"

She wanted to be dead, she says, glancing down. A wisp of straight brown hair slips from behind an ear across her thin face.
