This is TELL ME MORE from NPR News. I'm Michel Martin. Now we'd like to return to an issue that's in the news all too often. We're talking about gun violence, particularly that experienced by children. That's something the president touched on in his State of the Union address Tuesday night, and something that, in fact, dominated his speech last year. But when we talk about this issue, usually, tragically, we are talking about young people who've been killed.
A lot of parents like to think their kids will simply outgrow baby fat. But the risk of becoming a severely overweight adult can actually start as early as kindergarten, research suggests.
"As parents, as a society, as clinicians, we need to think about a healthy weight really early on," says Solveig Cunningham, who led the study. But that doesn't mean putting young children on calorie-restricted diets.
Neanderthals died out long ago, but their genes live on in us. Scientists studying human chromosomes say they've discovered a surprising amount of Neanderthal DNA in our genes. And these aren't just random fragments; they help shape what we look like today, including our hair and skin.
These genes crept into our DNA tens of thousands of years ago, during occasional sexual encounters between Neanderthals and human ancestors who lived in Europe at the time. They show up today in their descendants, people of European and Asian descent.
On Jan. 9, people in and around Charleston, W.Va., began showing up at hospitals: They had nausea, eye infections and some were vomiting. It was later discovered that around 10,000 gallons of toxic chemicals had leaked into the Elk River, just upstream from a water treatment plant that serves 300,000 people. Citizens were told not to drink or bathe in the water, and while some people are now using water from their taps, many still don't trust it or the information coming from public officials.
Back in 1958, a young biologist at Cornell University made a stunning discovery.
He took a single cell from a carrot and then mixed it with some coconut milk. Days went by and the cell started dividing. Little roots formed. Stems started growing. Eventually, a whole new carrot plant rose up from the single cell.
Imagine if you could perform a similar feat with animal cells, even human cells.
Oklahoma Attorney General Scott Pruitt has filed a brief in support of Hobby Lobby as its challenge to a portion of the Affordable Care Act moves forward at the U.S. Supreme Court.
Hobby Lobby is challenging a portion of the nation's new health care law that would require it to supply certain types of contraception to its employees. The Supreme Court is slated to hear arguments in March.

Exercise helps recovery after cancer treatment, but fatigue can make working out hard. Yoga can help reduce fatigue for breast cancer survivors, a study finds. It's one of a growing number of efforts using randomized controlled trials to see if the ancient practice offers medical benefits.
Women who took a yoga class three hours a week for three months reported less fatigue compared with a group of breast cancer survivors who did not do yoga.
Scientists have reconstructed the genetic code of a strain of bacteria that caused one of the most deadly pandemics in history nearly 1,500 years ago.
They did it by finding the skeletons of people killed by the plague and extracting DNA from traces of blood inside their teeth.
This plague struck in the year 541, under the reign of the Roman emperor Justinian, so it's usually called the Justinian plague. The emperor actually got sick himself but recovered. He was one of the lucky ones.
