In this installment of NPR's series Inside Alzheimer's, we're sharing a recent video of Greg O'Brien at home on Cape Cod, Mass. A longtime journalist, O'Brien was diagnosed with early-onset Alzheimer's disease in 2009.

The first time I interviewed Greg O'Brien, back in January, I asked him what he was most afraid of.

Amy and Dave Freeman are willing to risk brutal winters, thin ice and hordes of hungry mosquitoes to raise awareness about impending mining operations on the border of public lands in northern Minnesota.

A year without a shower takes a tremendous amount of dedication and passion. Why do the Freemans believe the Boundary Waters Canoe Area Wilderness is worth the sacrifice?

"The Boundary Waters belong to all of us. It's a national forest, it's federal lands. It's like a Yellowstone or a Yosemite," Dave says. "There's no other place like it on Earth."

Scientists have just made a breakthrough in understanding how clouds interact with the surrounding air by studying some of the most boring clouds you can imagine in unprecedented detail.

"If you ask a child to draw a cloud they would draw a white puffy cloud floating in the air all by itself — and that's the kind of cloud we were looking at," says Raymond Shaw, an atmospheric scientist at Michigan Technological University.

It was a routine launch for the Atlas V booster, which was carrying a Mexican satellite into orbit as it lifted off from Florida's Cape Canaveral on Friday morning. But the rocket's expanding exhaust plume was anything but ordinary.

What's come to be called "the nation's T. rex" now stands — though not in the United States. It's in Canada.

The nearly complete and much heralded Tyrannosaurus skeleton — the first ever owned by the Smithsonian's National Museum of Natural History — was discovered in 1988 by a Montana rancher, Kathy Wankel, and will eventually find a new home in a grand display in the Washington, D.C., museum.

If you watch the film The Martian, you'll see Hollywood explosions and special effects galore, but you'll also see some serious science.

Actor Matt Damon, who plays stranded astronaut Mark Watney, must calculate his way through food shortages, Martian road trips and other misadventures as he fights to find a way off the Red Planet.

Numbers are a matter of life and death for Damon's astronaut, and in this movie they're not pulled from thin air.

The Sooam Biotech Research Foundation's sleek marble building is on the outskirts of Seoul, South Korea. After passing through a guarded gate, visitors climb the steps to the entrance and a big door with tinted glass slides open.

"Hello, sir. Nice to meet you, sir," says David Kim, a researcher at the laboratory. "You can follow me. We can go into the clean room. It's the laboratory where we do the procedures — the cloning."

It's a typical morning at the Dupont Veterinary Clinic in Lafayette, La. Dr. Phillip Dupont is caring for cats and dogs in the examining room while his wife, Paula, answers the phone and pet owners' questions. Their two dogs are sleeping on the floor behind her desk.

"That's Ken and Henry," Paula says, pointing to the slim, midsize dogs with floppy ears and long snouts. Both dogs are tan, gray and white, with similar markings. "I put a red collar on Ken and a black collar on Henry so I can tell who's who."

We might not be able to remember every stressful episode of our childhood.

But the emotional upheaval we experience as kids — whether it's the loss of a loved one, the chronic stress of economic insecurity, or social interactions that leave us tearful or anxious — may have a lifelong impact on our health.
