About Ron Finley's TEDTalk

Ron Finley plants vegetable gardens in South Central LA — in abandoned lots, traffic medians, along the curbs. Why? For fun, for defiance, for beauty and to offer some alternative to fast food in a community where "the drive-thrus are killing more people than the drive-bys."

STEVE INSKEEP, HOST:

The American Psychiatric Association is about to release an updated version of its Diagnostic and Statistical Manual of Mental Disorders. The DSM helps mental health professionals decide who has problems such as depression, anxiety and schizophrenia.

Psychiatry's new manual, DSM-5, has been nearly 20 years in the making. During that time, scientists have learned a lot about the brain. Yet despite some tweaks to categories such as autism and mood disorders, DSM-5 is remarkably similar to the version issued in 1994.

Four years ago, 21 men with intellectual disabilities were emancipated from a bright blue, century-old schoolhouse in Atalissa, Iowa. They ranged in age from their 40s to their 60s, and for most of their adult lives they had worked for next to nothing and lived in dangerously unsanitary conditions.

Earlier this month, the Equal Employment Opportunity Commission won a massive judgment against the turkey-processing company at which the men worked. The civil suit involved severe physical and emotional abuse of men with intellectual disabilities.

Stimulating the brain with a very small electrical current through the forehead could boost a student's ability to learn and remember basic mathematics, a provocative experiment suggests.

The work, published online Thursday by the journal Current Biology, could help those who struggle with mental arithmetic. But the study was small and the long-term effect wasn't profound.

When the Senate voted Tuesday to make Marilyn Tavenner the official administrator of the Centers for Medicare and Medicaid Services, it was the first time the world's greatest deliberative body had approved someone to head the huge health agency since 2004.

That's right, you have to go way back to the Bush administration to find Dr. Mark McClellan, the last person to be officially put in the post.

This week, Google, already a leader in mapping, created more space between itself and its competitors by more deeply mining the data users provide the company when using its various services.

At the Google developers' conference in San Francisco on Wednesday, Daniel Graf, director of Google Maps, crowed about the company's mapping app for the iPhone — and couldn't quite stop himself from taking a dig at Apple.

"People called it sleek, simple, beautiful, and let's not forget, accurate," he said.

ROBERT KRULWICH, BYLINE: Excuse me. Come over here for just a second.

VERTAMAE GROSVENOR: Oh, get away.

KRULWICH: Come over here.

GROSVENOR: You smell.

A study published online recently in the journal Environmental Health Perspectives documented slightly elevated levels of arsenic in samples of chicken purchased at grocery stores in 10 cities in the U.S.

So how did trace amounts of this toxin end up in supermarket poultry?

Perhaps you've noticed a toddler's sagging swim diaper and wondered if it's really keeping the poop out of your neighborhood pool.

The Centers for Disease Control and Prevention has the answer for you: no.

Last summer, researchers at the federal public health agency collected 161 filter samples from public swimming pools in the Atlanta area. More than half of those samples, 58 percent, were contaminated with E. coli.

That, the CDC reported today, "signifies that swimmers introduced fecal matter into pool water."

People smell yummy to mosquitoes.

So yummy, in fact, that our scent is a big way the pesky insects track us down.

But just how much mosquitoes like Eau de Human may not be entirely up to the bugs.

Mosquitoes are more attracted to human odors when they're infected with the malaria parasite, scientists reported Wednesday in the journal PLOS ONE.
