Why Knuckles Crack

Apr 15, 2015

Scientists think they may have solved an old question about the cracking of knuckles: Why does it make that sound?

When Kevin Lopez opens the door to his Greenbelt, Md., apartment to greet a visitor he's never before met, he initially conceals his right hand.

"I'm self-conscious, definitely, about my right hand," he says. But eventually Lopez relaxes.

"I was born like this," he says. "As you can see, I don't have any fingers." It bothers the 20-year-old enough that he has volunteered to do something drastic: to have his right hand removed and replaced with another person's hand via surgery.

The Food and Drug Administration is weighing whether to allow a tobacco company to do something it's never done before — claim that one of its products is less risky than cigarettes.

The company, Swedish Match of Stockholm, has applied to the FDA to designate its General brand of snus (rhymes with "loose") as safer than other versions of tobacco.

A new technology called CRISPR could allow scientists to alter the human genetic code for generations. That's causing some leading biologists and bioethicists to sound an alarm.

Babies who are breast-fed may be more likely to be successful in life, a provocative study published Tuesday suggests.

The study followed more than 3,000 babies into adulthood in Brazil. The researchers found those who were breast-fed scored slightly higher in intelligence tests in their 30s, stayed in school longer and earned more money than those who were given formula.
