On a coastal marsh south of New Orleans, oil still saturates a 30-foot-wide stretch. Where hip-high grass should be, the oil has formed a hard, dark mat. If you dig though that crust, you find a thick, oozy layer of oil.
"It hasn't weathered or degraded much since it came ashore in early June," says scientist Scott Zengel, a contractor for the National Oceanic and Atmospheric Administration, who is overseeing the marsh survey crews.
Wednesday marks the first anniversary of the BP well explosion in the Gulf of Mexico. The eruption led to the worst oil spill in U.S. history. Beyond the cost to the environment, there was a tremendous human loss — 11 workers were killed in the initial explosion. For 15 years, tool pusher, Jason Anderson, worked for the company Transocean �"- a contractor BP hired to operate the well. Host Michel Martin speaks with his wife, Shelley Anderson, about her family's continued struggle to cope with the loss.

Researchers have found evidence that the placenta plays an important role in fetal brain development during the early stages of pregnancy.
Experiments in mice show that during a key period, the placenta becomes a source of the chemical serotonin, which helps determine the wiring of key circuits in the brain.
The finding, published in the journal Nature, could help explain what leads to brain disorders such as autism and schizophrenia. And it shows that the placenta does a lot more than simply transport nutrients from a mother to her unborn baby.
