Summary

Forensic DNA is supposed to be the end all be all when it comes to solving crime, so why are there so many false convictions when it comes to using DNA evidence? Today, Senior Producer Teresa Carey talks to Dr. Gregory Hampikian about forensic DNA, fingerprints, AI, and the limitations of scientific evidence in criminal investigations. Host, Dr. Samantha Yammine also explores the Effort Paradox (aka why doing things that are hard can feel good) and how using RICE (that’s rest, ice, compression, and elevation) for injuries is an outdated method for healing.  

 

Don’t forget that season two of Eye of the Storm premieres July 27th on Discovery and HBO Max.

With shortwave's sea camp, because when's the last time you had an ocean getaway?

Every Monday, we bring you in sites from a different ocean zone, starting with the sunlit surface until we hit the deep sea floor, where there's marine snow, weird critters, carbon sinks, and so much more.

But first, you've got to take the plunge.

Follow NPR's Shortwave wherever you get your

podcast.

We're told DNA has all the answers. It can tell us about our health, connect us with lost

0:34.9

relatives, and could make all the difference in a court case.

0:38.7

But when it comes to forensic science, you're not always getting samples from ideal conditions,

0:44.2

so things get a bit more complicated.

0:45.8

AI is better than humans at many things, and it fails at several things. You can't use the speedometer on your car to

0:58.6

measure the speed of an inch one. It's a perfect instrument, but it has limits. That's Dr. Gregory

1:06.0

Hemphiakian, talking about DNA and AI in forensics. And here's the big question. When someone's life is on the

line in a legal case, how do we know what evidence we can really trust? If you're a crime

enthusiast or not, this is a must listen. I'm Dr. Samantha Amin, and this is Curiosity Weekly

from Discovery. In this episode, Curiosity's senior producer Teresa Carey sits down with

1:29.1

Dr. Gregory and Pickean to dig into the use and misuse of DNA and AI in criminal investigations.

And later, we'll take a closer look at rice. Not the food, we covered that in episode 23,

1:41.8

but the classic treatment for sports injuries, rest, ice, compression,

1:45.7

elevation, it turns out it might not be the best approach after all. And if you're interested

1:50.6

in exploring extreme weather and its impact, catch season two of In the Eye of the Storm. It
