As Venezuela's president, Hugo Chavez thought in grandiose terms, and his country's vast oil riches enabled him to act on his vision. But Chavez died before he had to deal with the flaws in his model, and some hard choices await his successor.
Key to Chavez's notion of "21st Century Socialism" was the redistribution of Venezuela's oil earnings. The country's oil reserves — estimated by the Organization of Petroleum Exporting Countries to be the largest in the world — are worth tens of billions of dollars a year in potential revenue.
The French painter Renoir, one of the creators of impressionism, is the subject of a French film that's in release across the U.S. It imagines the last years of the painter's life — surrounded by glorious rolling hills, doting housemaids and a new young model who becomes his muse. It's at least the second film to capture the master in motion.
Scientists reported Wednesday that they had developed a way to measure how much pain people are experiencing by scanning their brains.
The researchers hope the technique will help doctors treat pain better, but the work is also raising concerns about whether the technique might interfere with doctors simply listening to their patients.
Now, when someone is in pain, a doctor has no way to judge its severity except to ask questions, a method that often is inadequate.
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.
Freshlyground has been one of the most talked about bands out of post-apartheid South Africa. One reason is the voice of lead singer Zolani Mahola. Mahola is a powerhouse; she and six other black and white musicians from around southern Africa make up the group. They came together in 2002 to forge a new sound, repackaging folk roots and classic African pop with a slick veneer of international pop production.
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.
It's no secret that many of the nation's roads are in pretty bad shape. In the latest report card from the American Society of Civil Engineers, the condition of America's highways rated a grade of D.
Congestion is a big problem, and so is upkeep. Most states rely on gas taxes to raise the money for repairs and new construction, but that funding source is not the stream it used to be, says James Corless of Transportation for America.
