| 0:00.0 | This is Science Friday. I'm Ira Flato. A bit later in the hour, checking in with science educators about how they're teaching students during the pandemic, and the book club continues. But first, you don't need me to tell you that these are stressful times, and that stress is taking a toll on many of us. But can trauma today have effects on generations |
| 0:24.3 | still to come? Researchers are looking into if and how traumatic experiences might cause epigenetic |
| 0:32.5 | changes. Now, those are changes in how genes are turned on and off in an animal's offspring. |
| 0:38.9 | Joining me now is one of those researchers, Bianca Jones Marlin, a neuroscientist and Simon's postdoctoral fellow at Columbia University. |
| 0:48.3 | Dr. Marlin is an incoming assistant professor of psychology and neuroscience, |
| 0:52.9 | and she will be opening her lab at Columbia University |
| 0:55.8 | Zuckerman Institute in 2021, and she's the subject of one of our episodes of our breakthrough video series. |
| 1:03.6 | You can watch all of those at breakthroughfilms.org. Welcome to Science Friday. Thank you for having me. Let's start with some basics if we can. |
| 1:14.8 | We're taught that genes are the way that information passes from one generation to another, |
| 1:20.3 | and traits are either nature or nurture, but this sounds as if it's somewhere in between. |
| 1:25.9 | Can you walk us through what's going on here? |
| 1:28.1 | Yes. So our genes don't change. Our genes are information coming from our parents that are |
| 1:32.8 | passed down to us. However, epigenetic markers means epi above genetics are genes. |
| 1:39.5 | There are markers around our genes that say whether or not they'll be turned on or turned |
| 1:43.4 | off, whether or not they'll be read, whether or not they'll be turned on or turned off, whether or not |
| 1:44.2 | they'll be read, whether or not they'll be what we call expressed. And this is really the essence |
| 1:49.1 | of bringing in that communication and that experience from our parents. Biology has a setup to |
| 1:55.6 | adapt to our surroundings, and that's a huge learning component, the nurture component. But what about preparing us for an |
| 2:02.8 | experience that we haven't come to yet? That's what parents are really good for. They teach their |
| 2:08.4 | offspring to navigate the world and to live in the environment. And it seems like biology has set |
| 2:13.7 | parents up to inform their offspring about how to navigate the environment without even having |
| 2:19.4 | to ever meet them. When you say they're set them up, do you mean they're passing genetic |
