Rae Ellen Bichell

Rae Ellen Bichell reports for the Mountain West News Bureau out of KUNC in Colorado. 

Before joining the team, she covered everything from Ebola to butterfly evolution and space toilets as a science reporter for NPR. She also tried freelancing for a couple years in Helsinki, Finland, originally under a Fulbright grant.

Now based in northern Colorado, she spends her free time reading, playing indoor soccer (not very well) and doing a crazy sport called canyoneering.

Most animals die once they can no longer have kids, but men and women tend to totally buck this trend, living decades beyond their reproductive years despite drastic changes in their bodies.

Eid al-Adha, an important Muslim holiday, starts on Monday in many countries. The Festival of Sacrifice, which marks Abraham's willingness to sacrifice his son, involves days of feasting and celebration. But the holiday has health officials in some countries — Afghanistan, in particular — wringing their hands about health risks. It's the feasts that are the problem — specifically, the meat.

A rocket took off Thursday evening from Cape Canaveral, Fla., as part of a mission by NASA and the University of Arizona to send a robot to an asteroid. The goal: Bring back ancient dust.

Most of the world didn't know anyone lived in the highlands of Papua New Guinea until the 1930s, when Australian gold prospectors surveying the area realized there were about a million people there.

When researchers made their way to those villages in the 1950s, they found something disturbing. Among a tribe of about 11,000 people called the Fore, up to 200 people a year had been dying of an inexplicable illness. They called the disease kuru, which means "shivering" or "trembling."

The rumbling started on the afternoon of May 22, 1960. Sergio Barrientos, then about 8 years old, was walking down a street in his hometown in southern Chile when the ground started to shake. He remembers electrical wires swinging from the telephone poles — so violently that they slapped each other from opposite sides of the street.

"At the same time, I saw some of the chimneys falling down through the roofs of the houses," says Barrientos.

To a mathematician, it's a violent explosion that shoots out missiles of hot, wet air, slamming a turbulent cloud of moisture into anybody or anything that crosses its path.

To the rest of us, it's a sneeze.

At about 8 a.m. ET today, far above Earth, astronaut Jeff Williams floated out a hatch and then welcomed Kate Rubins into the void.

"OK Kate, come on out," said Williams.

When Kristin Armstrong pedaled across the Olympic finish line to win a cycling gold in Rio de Janeiro, her nose was bleeding and her 5-year-old son was waiting for her.

The 42-year-old told reporters that people constantly ask why she keeps competing despite her age and multiple hip surgeries.

Her response? "Because I can."

A few months ago, when Dr. Thomas Lee logged in to his patients' electronic medical records to renew a prescription, something unexpected popped up. It was a notice that one of them had died.

Lee, a primary care doctor at Brigham and Women's Hospital in Boston, was scheduled to see the patient in three days.
