Researchers in California described Wednesday their new method for mass-producing the key ingredient for the herbal drug artemisinin, the most powerful antimalarial on the market. Already, the French drugmaker Sanofi is ramping up production at a plant in Italy to manufacture the ingredient and the drug.

Global health advocates say they expect this new method of producing artemisinin will at last provide a stable supply of the drug and cut the overall cost of malaria treatment.

First lady Michelle Obama gave a personal and emotional speech Wednesday in Chicago as she stepped into the debate over gun control.

"Right now, my husband is fighting as hard as he can and engaging as many people as he can to pass common-sense reforms to protect our children from gun violence," she said.

The first lady was in her hometown to encourage business leaders to donate millions of dollars to programs for at-risk youth.

No one knows if Atlanta's school superintendent or any of the people accused of falsifying test results will go to jail, but they wouldn't be the first if they do.

Lorenzo Garcia, the former superintendent of schools in El Paso, Texas, has been sitting in a federal prison since last year. He's the nation's first superintendent convicted of fraud and reporting bogus test scores for financial gain.

On a normal day, Kansas City, Mo., processes more than 70 million gallons of raw sewage. This sewage used to be a nuisance, but Kansas City, and a lot of municipalities around the country, are now turning it into a resource for city farmers hard up for fertilizer.

After the sewage has been processed at a treatment plant, it's piped out to Birmingham Farm on the north side of the Missouri River.

Since the November election, 240 California prisoners facing potential life sentences have been set free. That's because voters changed California's tough three strikes sentencing law.

As NPR reported in 2009, that law sent thousands of people to prison for terms of 25 years to life for minor, nonviolent crimes. Now those prisoners can ask the court to have their sentences reduced.

One of those set free under the new law is Shane Reams. He owes his freedom in no small part to his mother Sue's 17-year campaign to change the law.

A rat with some human genes could provide a better way to test Alzheimer's drugs.

The genetically modified rat is the first rodent model to exhibit the full range of brain changes found in Alzheimer's, researchers report in The Journal of Neuroscience.

Republicans don't often make high-profile speeches at Howard University, one of the country's most prominent historically black schools. But on Wednesday, Kentucky Sen. Rand Paul will talk to Howard students about how his party can be more inclusive.

Paul believes one answer is libertarianism — and party leaders are starting to think he might be on to something.
