Solving The Sleep & Alzheimer's Puzzle
21 november 2019 · 8 min
We know that people with Alzheimer's often have sleep problems. But does it work the other way? Do problems with sleep set the stage for this degenerative brain disease? Jon Hamilton introduces us to some scientists looking into that connection. In a recent study, researchers observed a key role deep sleep potentially plays in maintaining brain health and protecting the brain against Alzheimer's.

Saving Water One Flush At A Time
19 november 2019 · 10 min
Happy World Toilet Day! Flushing toilets can consume a lot of water, so Tak-Sing Wong, a biomedical engineer at Penn State University, is trying to minimize how much is needed. Wong developed a slippery coating for the inside of a toilet bowl. It can potentially move human waste more efficiently, leaving a cleaner bowl and using less water.

An Eyewitness to Extinction
15 november 2019 · 9 min
While doing field work in Central America in the 1990's, biologist Karen Lips noticed the frogs she was studying were disappearing. Scientists in other parts of the world had documented the same thing - frogs and amphibians dying at an alarming rate. For years no one knew what was killing the animals until, finally, a bit of good luck helped solve the mystery. Follow host Maddie Sofia on Twitter @maddie_sofia. Email the show at shortwave@npr.org.

Crows Don't Forget
30 oktober 2019 · 9 min
Crows have gotten a bad rap throughout history. Think about it. A group of them is called a "murder." To get some insight into crows and perhaps set the record straight, we talked to Kaeli Swift. She's a lecturer at the University of Washington and wrote her doctoral thesis on crow "funerals." Lees meer
In an earlier version of this episode, we used the word "spooky" to describe crows. Because that word has a history of being used as a racial slur, we chose to replace it with the words "scary" and "creepy." Thanks to our listeners who helpfully pointed this out to us, and we apologize. You can learn more about this from our friends at Code Switch.

Artificial intelligence might not be as smart as we think. University and military researchers are studying how attackers could hack into AI systems by exploiting how these systems learn. It's known as "adversarial AI." Some of their experiments use seemingly simple techniques. Dina Temple-Raston has been looking into this for her special series, I'll Be Seeing You.
