| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com. |
| 0:05.8 | I'm Cody Goff. And I'm Ashley Hamer. Today you learn about how mice seem to feel each other's pain, |
| 0:11.3 | why our known solar system just got a little bigger, and how a malaria cure |
| 0:16.3 | turned into your ginontonic. |
| 0:18.6 | Let's satisfy some curiosity. |
| 0:20.6 | Empathy is what lets you feel a loved one's pain. |
| 0:25.0 | Mice can feel each other's pain too. |
| 0:28.0 | And for the first time, researchers have shown that they can also feel each other's pain relief. |
| 0:33.6 | And understanding why can help scientists learn more about how empathy works |
| 0:38.2 | in humans. |
| 0:39.2 | For this study, Stanford scientists did several experiments on pairs of mice. |
| 0:45.0 | In one instance, one mouse got an arthritis-inducing shot in its back paw. |
| 0:50.1 | The other mouse was untouched. |
| 0:52.4 | But after hanging out together for an hour, |
| 0:54.6 | the bystander mouse acted like it got a shot too. The injured mice showed extra tenderness |
| 1:00.4 | in the leg that got injected when scientists poked at it. |
| 1:03.6 | Not surprising. |
| 1:04.6 | But when researchers poked at the bystander mouse, it acted like it was in just as much pain |
| 1:09.8 | and in more places. |
| 1:12.2 | In a different experiment, both mice got a pain-inducing shot, but one lucky mouse |
| 1:17.7 | also got a soothing dose of morphine. And again, the mouse that didn't get the morphine acted pain-free after spending a few hours with his |
| 1:26.6 | morphine-soothed buddy. |
