AUDIE CORNISH, HOST:
And I'm Audie Cornish. Scientists throughout the west are investigating a mysterious disappearance. Mule deer are vanishing. In Colorado, Wyoming and Utah, populations are half what they were in the 1970s. From Aspen Public Radio, Luke Runyon reports on some possible reasons.
Coptic Christians will celebrate Christmas on Monday, and many will do so outside their native Egypt. Since the revolution there, their future in the country has looked uncertain, and many are resettling in the United States.
Their population in the U.S. may have grown by nearly 30 percent, according to rough estimates. One church that has felt its membership swell with new arrivals from Egypt is in the Queens borough of New York. St. Mary and St. Antonios Coptic Orthodox Church boasts more than 1,000 families, says the Rev. Michael Sorial.
The first key to thinking about 3-D printers is this: Do not think printer. Think magic box that creates any object you can imagine.
In the box, razor-thin layers of powdered material (acrylic, nylon, silver, whatever) pile one on top of the other, and then, voila — you've got a shoe, or a cup, or a ring, or an iPhone case.
It's miraculous to see. Press a button, make anything you want. But just how important is 3-D printing? Unlike earlier big-deal technologies (like, say, the tractor) 3-D printing won't really replace what came before.
South Korean men play games at a downtown park in Seoul on Nov. 1. Recent data suggest that South Korea is now the fastest-aging country on Earth.

The Gangseo District Center for Dementia is one of Seoul's 25 community-level centers helping families care for dementia patients. The rapid increase in dementia is just one consequence of South Korea's rapidly aging population.

High school student Kim Dong-hyun undergoes a simulated experience as an incapacitated elderly person who is hoisted from his bed into a chair by means of a winch and sling. Training at the Seongnam Senior Complex outside Seoul is intended to help young people understand what the elderly are experiencing.
At a clean and sunny community center in Seoul, the South Korean capital, senior citizens make clay models of their own faces in an arts class. Some of the faces are vivid and lifelike. Others are expressionless and indistinct. The project is intended to help the seniors remember what they look like.
This is the Gangseo District Center for Dementia. Since 2006, Seoul has opened a dementia center in each of the city's 25 urban districts.
UPDATED: 4:50 p.m. Looking for a little weekend reading? The Food and Drug Administration has just the thing. On Friday, the agency released two proposed rules designed to boost the safety of the nation's food supply, encompassing hundreds of pages.
No matter how old people are, they seem to believe that who they are today is essentially who they'll be tomorrow.
That's according to fresh research that suggests that people generally fail to appreciate how much their personality and values will change in the years ahead — even though they recognize that they have changed in the past.
Daniel Gilbert, a psychology researcher at Harvard University who did this study with two colleagues, says that he's no exception to this rule.
The wind energy industry is dependent on something even more unpredictable than wind: Congress. Hidden in the turmoil over the "fiscal cliff" compromise was a tax credit for wind energy.
Uncertainty over the credit had lingered long before the last-minute political push, causing the industry to put off further long-term planning. So while the now-approved tax credit revives prospects for an industry facing tens of thousands of layoffs, don't expect to see many new turbines coming up soon.
Voting for this year's Oscar nominations was supposed to have closed today — but it's been bumped a day, in the wake of complaints about the new online voting system put in place by the Academy of Motion Picture Arts and Sciences.
Hollywood Reporter analyst Scott Feinberg tells NPR's Audie Cornish that the system was supposed to make life easier for academy members.
"Going to e-voting would allow voters to vote from anywhere in the world, if they're on vacation or whatever during the holidays, and just make the process itself more streamlined and efficient."
Pedestrian and cyclist fatalities are increasing nationwide, according to the National Highway Traffic Safety Administration, and Los Angeles and New York City have the highest rates of those deaths.
In Los Angeles, where the car is the major mode of transportation, hit and runs involving pedestrians occur almost daily. But these crimes can be the most difficult for law enforcement to investigate and solve.
Holidays are typically a festive time, with breaks from the routine, meals with loved ones, maybe even some gifts. But for many families across the U.S., the season comes with intense stress: Roughly 1 in 5 families with children are not getting enough food.
For some, free or reduced-price school meals have become a major source of basic nutrition. When schools close for the holidays, many of those families struggle to fill the gap.
