Summary

Even In A Pandemic, Science Class Is In Session This academic year, school campuses across the United States look very different. Instead of crowded hallways and bustling classrooms, students are spaced six feet apart, sometimes behind plastic barriers, while others are at home on camera in a video call. Since some states do not weigh in on school operations, communities witnessed a myriad of learning approaches, such as fully virtual, fully in-person, or a mixture of both. All are subject to change as COVID-19 rates fluctuate throughout regions. For instance, on October 1, all New York City public schools reopened and shifted 500,000 students to in-person class. Meanwhile, on Wednesday, October 21, Boston Public Schools announced that it suspended all in-person learning as numbers of COVID-19 cases rose in the region. Teachers, students, parents, caregivers, and staff have all felt the stress and uncertainty during the COVID-19 pandemic. The situation is academically, mentally, and emotionally overwhelming. While the pandemic has presented many challenges in learning, STEAM educators are adapting. They are coming up with creative solutions to continue to meet the needs of all students, like holding outdoor biology classes, dissecting flowers at home, and even delivering materials and devices to students who need them.   STEAM educators Rabiah Harris, Josa Rivas, and Rick Erickson join Ira for a roundtable discussion on how the pandemic has impacted school this academic year.  Can Trauma Today Affect Future Children? We typically think of a traumatic event as a sudden thing—something that has a beginning and an end. Stress and trauma can of course have lasting psychological effects—and, in some cases, physical effects such as elevated blood pressure or premature aging. But now researchers are considering whether stress to an organism can be somehow transmitted to that animal’s future offspring, via epigenetic changes that modify how genetic code is expressed in the young. Bianca Jones Marlin is a neuroscientist studying such changes. In one study, she found that if researchers trained mice to associate the smell of almonds with an electric shock, the offspring of the mice tended to be afraid of an almond smell—even if they were raised separately, by foster parents that had no experience with the odor. Jones Marlin joins Ira to talk about her research, and her experience as a young researcher starting her own lab in the neurosciences. Making Peace With The End Of Your Species Welcome to week four of the Science Friday Book Club’s reading of ‘New Suns’! Our last short story assignment is ‘The Shadow We Cast Through Time’ by Indian writer Indrapramit Das. On a far-off planet, a human colony has been cut off from the rest of space: but they’ve also encountered other life, a fungus-like organism that infects and distorts human bodies into horned “demon”-like creatures. And as one human woman, Surya, approaches her death at their hands willingly, she makes a discovery that speaks of a new future for both species. Author Indrapramit Das joins SciFri producer Christie Taylor and Journal of Science Fiction managing editor Aisha Matthews to talk about creating new worlds, and the “modern mythology” of writing science fiction and fantasy.

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

still to come? Researchers are looking into if and how traumatic experiences might cause epigenetic

changes. Now, those are changes in how genes are turned on and off in an animal's offspring.

Joining me now is one of those researchers, Bianca Jones Marlin, a neuroscientist and Simon's postdoctoral fellow at Columbia University.

Dr. Marlin is an incoming assistant professor of psychology and neuroscience,

and she will be opening her lab at Columbia University

Zuckerman Institute in 2021, and she's the subject of one of our episodes of our breakthrough video series.

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
