Bioengineers are developing microchips, about the size of a thumb, that can behave like human organs. Donald Ingber, director of the Wyss Institute for Biologically Inspired Engineering, discusses how the "organ-on-a-chip" works and why the technology could replace the animal model for drug testing.

That's because Chinese consumers trust American brands more than their own, says Shaun Rein, founder of China Market Research, who studies Chinese consumer behavior. Rein says that in China, McDonald's is seen as providing safe and wholesome food.
Gene Autry, Bette Davis and Buster Keaton are just a few of the names that draw flocks of tourists to Forest Lawn Memorial Park in the Hollywood Hills.
But there's a lesser-known man among the silver screen legends: Frank Inn, a pioneering animal trainer who made stars out of animals.
Inn's own life closely resembled a Hollywood film. Born into a strict Quaker family from Indiana, Inn set his sights on the movie business early. In the mid-1930s, while still in his teens, Inn hitchhiked west to Los Angeles.
The Los Angeles City Council voted Tuesday to shut down all of the medical marijuana dispensaries in the city. That's no easy task. There are more than 800 of them — more than the number of Starbucks coffee shops in Los Angeles. But after years of struggling to regulate pot shops, city officials have decided to prohibit them altogether.
For decades, the primary goal of those who would fix the U.S. health system has been to help people without insurance get coverage. Now, it seems, all that may be changing. At least some top Republicans are trying to steer the health debate away from the problem of the uninsured.
The shift in emphasis is a subtle one, but it's noticeable.

"I was planning on getting a degree in international relations, but with financial aid and how difficult it is to pay for college and everything," she says. "So when Siemens came along and gave me the offer, it was too good of an opportunity to just let it go.

A drop of blood from a finger-prick is all that's needed to test for HIV. A nurse draws a sample from a student in a mobile clinic on March 8, 2011 in KwaZulu-Natal, South Africa.
The province of KwaZulu-Natal has emerged as the epicenter of South Africa's HIV epidemic. South Africa already has more people infected with HIV than any other country in the world, but parts of KwaZulu-Natal have HIV rates that are more than twice the national average.
Now in addition to HIV and AIDS, the province is also dealing with a major tuberculosis epidemic.
In the northeastern part of KwaZulu-Natal, dusty dirt tracks wind through pastures and fields of sugar cane. The hillsides are dotted with small huts made of cinder blocks and field stones.
