| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from |
| 0:04.9 | Curiosity.com. I'm Cody Gough. And I'm Ashley Hamer. Today you learn about a |
| 0:09.2 | trick for easing the memory of a traumatic event, why extreme temperatures mess with your batteries and what you can do about it, |
| 0:16.0 | and how researchers use machine learning to discover a powerful antibiotic for the first time. |
| 0:21.0 | Let's start us out some curiosity. |
| 0:24.0 | Researchers have identified a pretty effective way to ease the memory of traumatic events. |
| 0:29.0 | And I mean, you know the bad things happen sometimes. |
| 0:32.0 | That's just a fact. Once in a while the memory of a bad thing can do even more damage than the thing itself. |
| 0:39.0 | But recent research suggests that a strategy called focused attention could help people recover from memories like this. |
| 0:47.0 | Basically, if you focus your attention, focused attention, get it, on neutral aspects of the scene, you might remember less about the most painful parts. |
| 0:58.0 | Strong emotions can make memories more vivid. That's great when you want to remember your wedding day, but not so great when you want to forget a car crash. |
| 1:06.0 | For some people, traumatic memories like those can play and replay and their minds for years. |
| 1:12.0 | That kind of obsessive recollection can... replay in their minds for years. |
| 1:13.0 | That kind of obsessive recollection can lead to PTSD or depression. |
| 1:17.0 | That's especially risky for people whose jobs require them to encounter some emotionally |
| 1:22.2 | challenging stuff, like first responders, therapists, and teachers. |
| 1:27.0 | But regardless of your occupation, this strategy could really take the emotional sting out of painful or traumatic memories. |
| 1:35.0 | There are two ways this focused attention strategy can help, when you experience an event in |
| 1:40.0 | the first place and when you recall it afterward. A recent study on the first |
| 1:44.5 | approach had people take a look at some pictures of things that were either |
| 1:47.8 | neutral like trees or negative like bloody faces and focus either on what was in the foreground or what was in the background. |
| 1:56.0 | Later when the participants were asked to recall what they had seen, |
