Presumptive Democratic presidential nominee Hillary Clinton was in Springfield, Ill., Wednesday where she sought to use the symbolism of a historic landmark to draw parallels to a present-day America that is in need of repairing deepening racial and cultural divides.

The Old State Capitol — where Abraham Lincoln delivered his famous "A house divided" speech in 1858 warning against the ills of slavery and where Barack Obama launched his presidential bid in 2007 — served as the backdrop for Clinton as she spoke of how "America's long struggle with race is far from finished."

Episode 711: Hooked on Heroin

When we meet the heroin dealer called Bone, he has just shot up. He has a lot to say anyway. He tells us about his career--it pretty much tracks the evolution of drug use in America these past ten years or so. He tells us about his rough past. And he tells us about how he died a week ago. He overdosed on his own supply and his friend took his body to the emergency room, then left.

New British Prime Minister Theresa May announced six members of her Cabinet Wednesday.

Amid a sweeping crackdown on dissent in Egypt, security forces have forcibly disappeared hundreds of people since the beginning of 2015, according to a new report from Amnesty International.

It's an "unprecedented spike," the group says, with an average of three or four people disappeared every day.

The Republican Party, as it prepares for its convention next week has checked off item No. 1 on its housekeeping list — drafting a party platform. The document reflects the conservative views of its authors, many of whom are party activists. So don't look for any concessions to changing views among the broader public on key social issues.

Many public figures who took to Twitter and Facebook following the murder of five police officers in Dallas have faced public blowback and, in some cases, found their employers less than forgiving about inflammatory and sometimes hateful online comments.

As Venezuela unravels — with shortages of food and medicine, as well as runaway inflation — President Nicolas Maduro is increasingly unpopular. But he's still holding onto power.

"The truth in Venezuela is there is real hunger. We are hungry," says a man who has invited me into his house in the northwestern city of Maracaibo, but doesn't want his name used for fear of reprisals by the government.

The wiry man paces angrily as he speaks. It wasn't always this way, he says, showing how loose his pants are now.

Ask a typical teenage girl about the latest slang and girl crushes and you might get answers like "spilling the tea" and Taylor Swift. But at the Girl Up Leadership Summit in Washington, D.C., the answers were "intersectional feminism" — the idea that there's no one-size-fits-all definition of feminism — and U.N. climate chief Christiana Figueres.

Scientists Grow New Hair In A Lab, But Don't Rush To Buy A Comb

Oct 21, 2013

With a tiny clump of cells from a man's scalp, scientists have grown new human hair in the laboratory.

But don't get too excited. A magic cure for baldness isn't around the corner. The experimental approach is quite limited and years from reaching the clinic — for many reasons.

The scientists have grown the hair only on a tiny patch of human skin grafted onto the back of a mouse. And as wispy locks go, the strands are pretty pathetic. Some hairs were white, and some didn't even make their way out of the skin.

Nevertheless, the proof-of-concept study, reported Monday in the Proceedings of the National Academy of Sciences, overcame a major obstacle to increasing the quantity of hair on your head.

Currently, people with hair loss have two options: drugs and surgical transplantation. "The drugs available work reasonably well at maintaining the hair you have," says Angela Christiano, a professor of dermatology at Columbia University Medical Center who led the study. "And with transplantation, you can move hair around the head, like from front to back. But neither [method] is known for being a way to actually grow new hair."

For that, scientists needed a way to make new hair follicles.

All human hair grows inside follicles, which are little tubes. When you're a baby developing inside the womb, cells in the skin decide where to put the follicles — and thus, your hair. Follicles go on legs, arms and head. But you don't get any on your palms, the soles of your feet and a few other places.

Once you're born, this pattern of hair doesn't change. The follicles may decide to go kaput later in life or start producing peach fuzz, as with male pattern baldness. But your skin never makes new follicles.

That's where Christiano and her team at Columbia University have made progress. Working together with Colin Jahoda in Durham University in England, they figured out a way to trick adult skin into growing new follicles and eventually new hair.

They took a special type of skin cell from seven men with male pattern baldness and grew them up in a Petri dish. Previous studies had just let the cells replicate on a 2D surface, but Christiano and her colleagues coerced the cells into clumping together and forming little balls. That slight variation made all the difference in the world.

The team put the spheres of cells inside a patch of human skin and grafted it onto a mouse. Six weeks later, the cells grew whole new hair follicles and tiny wisps of hair. The procedure worked in five of the seven men tested.

But the hair follicles weren't normal. They were missing sebaceous glands that keep the skin moist. And the hair grew out of the skin at funny angles.

"Before we can move into clinical trials, the procedure would have to be animal-free," Christiano says. "And we need much more hairs than we have. But conservatively, I'd love to have the method in clinical trials in three to five years."

Other scientists in the field are a bit more cautious.

"You can ask anyone how long it will take something in the future to happen, and the answer will always be three to five years," says Luis Garza, a dermatologist at Johns Hopkins University who wasn't involved in the study.

"Any time you grow cells in the laboratory and inject them back inside people, there's a chance the cells could overgrow," Garza tells Shots. That means the cells could form tumors or even some cancers. Plus, a technique like this, Garza speculates, would be much more expensive than regular hair transplantation.

Nevertheless, the findings are a major advance in the field, he says. "Before this method goes into clinical trials, we've got a mountain climb,and it's miles of steep terrain ahead," he says. "But the findings of Dr. Christiano definitely get us closer."
