...look like a relic of the past, with its clay tiles, ornate sidings and those Chinese New Year red balloons, but like much in China, it's spanking new. Yet relics of the past are good business here. In one of the mall's countless stores, apron-clad Zhang Lijie is chipping away the rock around a 120 million-year-old fish fossil that she plans to sell for $3. Zhang, 38, went from selling vegetables a decade ago to hawking fossils on a street corners. Now, she owns her own store, The Treasure Mansion, which stocks the fossilized remains...
...market in the world. There's a noticeable hierarchy here, with the newly minted dealers competing with each other, as well as peddlers of gaudy flowers and pirated books, out on the street. More established dealers set up booths in a crowded three-story building. Only the shrewdest, like Zhang, can afford the stand-alone storefronts...

After adjusting for variables such as maternal age, number of births prior to abortion and gestational age at the time of abortion, researchers found no increase in risk of ectopic pregnancy, miscarriage, premature birth or low birth weight in the medication group, as compared with the women...
...disparity between the new results and the earlier study? Zhang points to the small sample size and self-reported data in the earlier study, compared with Zhang's large cohort and national-registry information. What's more, the focus of the previous study was not abortion per se, but general risk factors for ectopic pregnancy, including women's history of smoking and pelvic infectious disease. "In some ways, they found this association accidentally," says Zhang, "and the author did not provide any explanation. We weren't sure whether that finding was just by chance or whether it was real...
