| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com. |
| 0:06.3 | I'm Cody Gough. And I'm Ashley Hamer. |
| 0:08.3 | Today you learn about how stress during pregnancy can influence the chances of the baby being born a boy or a girl, |
| 0:15.0 | how the physics of skipping stones can make space exploration safer, |
| 0:19.0 | and how to stop overspending. |
| 0:21.0 | Let's satisfy some curiosity. Stress, am I right? Stress affects |
| 0:26.9 | the entire body and for pregnant people it affects the baby too. New research suggests that moms to be who are stressed out during conception |
| 0:36.4 | and the earliest phases of pregnancy might be more likely to have a child of a certain sex? |
| 0:43.4 | Stick around at the end of the episode for the gender reveal. |
| 0:46.5 | No, no, we're not doing that. |
| 0:48.1 | It's, it's a girl. |
| 0:49.5 | Stress could make having a girl more likely. |
| 0:52.6 | Okay, fine. |
| 0:54.2 | Well, anyway, here's how the study went down. |
| 0:56.8 | Researchers found 164 people who were toward the end of their first trimester. |
| 1:02.3 | Each one filled out some surveys about their stress |
| 1:04.7 | levels and they donated a lock of their hair. Several months later the |
| 1:09.1 | researchers got back in touch with them to find out the sex of the baby. |
| 1:14.0 | Just over a hundred of the participants carried their baby to term and were able to finish |
| 1:18.2 | the last leg of the research project. |
| 1:21.6 | Once that was all finished, the researchers started analyzing the data and they |
| 1:25.5 | divided the new parents into groups, those who had boys and those who had girls. |
