A 107-year-old Arkansas man who held off police is dead after a SWAT team stormed a house during a reported exchange of gunfire on Saturday afternoon.
Police officers had arrived at the house in Pine Bluff, Ark., to investigate a report of a domestic disturbance. They spoke with two people, who said Monroe Isadore had pointed a gun at them. Isadore was in his bedroom, they said.
We spend about one-third of our lives sleeping, but much of that function remains a mystery. Weekend Edition Sunday is asking some pretty fundamental, yet complicated, questions about why we do it and why we can't seem to get more of it.
Dr. Matthew Walker says the question of why we sleep remains "that archetypal mystery."
Walker, the principal investigator at the sleep lab the University of California, Berkeley, works with patients who suffer from sleep abnormalities. He says the complexity of sleep makes the research that much more fascinating.
The effects of climate change often happen on a large scale, like drought or a rise in sea level. In the hills outside Missoula, Mont., wildlife biologists are looking at a change to something very small: the snowshoe hare.
Life as snowshoe hare is pretty stressful. For one, almost everything in the forest wants to eat you.
Alex Kumar, a graduate student at the University of Montana, lists the animals that are hungry for hares.
"Lynx, foxes, coyotes, raptors, birds of prey. Interestingly enough, young hares, their main predator is actually red squirrels."
