Prehistoric humans didn't have toothbrushes. They didn't have floss or toothpaste, and they certainly didn't have Listerine. Yet somehow, their mouths were a lot healthier than ours are today.
"Hunter-gatherers had really good teeth," says Alan Cooper, director of the Australian Centre for Ancient DNA. "[But] as soon as you get to farming populations, you see this massive change. Huge amounts of gum disease. And cavities start cropping up."
Shen Lixiu, 58, says she had her front teeth kicked out in a re-education through labor camp. Chinese authorities say they are considering "reforms" to a system that is coming under increasing public criticism.
A lot of journalism about China focuses on the country's rapid and stunning changes, but equally telling are the things that stay the same. I did my first story on China's re-education through labor camps back in 2001.
I met a former inmate named Liu Xiaobo for lunch in Beijing. Liu, soft-spoken and thoughtful, had written an article mourning those who had died in the 1989 Tiananmen crackdown. He had also called for democracy.
So, one day, police took him from his house and charged him with "slandering the Communist Party" and "disrupting social order."

The Obama administration is following through on its relatively newfound support of gay marriage. On Friday, the administration filed a legal brief with the Justice Department that urges the Supreme Court to strike down a key part of the Defense of Marriage Act.
Syria's main opposition group is declining invitations to international meetings to protest what it calls the "shameful" failure by world leaders to end violence there.
"The international silence on the crimes committed every day against our people amounts to participating in two years of killings," the Syrian National Coalition said in a statement released Friday and reported on by Agence France-Presse and other news organizations.
Researchers who studied pieces of the meteor collected near Lake Cherbarkul say it was a common chondrite meteor. The largest of the 53 fragments was one centimeter in diameter. Photo provided by the Urals Federal University Press Service.
The meteor that caused at least 1,000 injuries in Russia after a startling and powerful daytime explosion one week ago has been identified as a chondrite. Russian scientists who analyzed fragments of the meteor, whose large size and well-documented impact made it a rarity, say that its composition makes it the most common type of meteor we encounter here on Earth.

Disease detectives are kind of the rock stars of public health.
They travel around the world, on a moment's notice, to track down an Ebola outbreak in Uganda or stop a cholera epidemic in Haiti. And Kate Winslet and Lawrence Fishburne played them in the movie Contagion, for crying out loud.
In this Wednesday, Feb. 20, 2013 photo, a young vendor waits for clients alongside woven reed mats of the type purchased by fleeing Islamists, apparently to camouflage their vehicles, in Timbuktu, Mali.

You're going to need a bigger fishbowl.
Scientists searching for invasive species in Lake Tahoe scooped up a bright orange goldfish measuring nearly a foot and a half long and weighing more than 4 pounds, according to the website Live Science. (You can see it here.)
Environmental scientist Sudeep Chandra says a survey has uncovered a "nice corner" of the lake where about 15 other giant goldfish were living, apparently after being dumped there by aquarium owners.
