Summary
Learn about how quickly certain people adjust to time changes; how you can help slow jungle loss; and why ice cubes grow spikes.
Early birds adjust to time changes faster than night owls by Grant Currin

Spiky ice cubes by Ashley Hamer (Listener question from Monica in Los Angeles)
- Occasionally the ice cubes in my freezer’s ice trays will develop a stalagmitelike shape without any obvious, unusual interference. Can you please explain what causes this? (2007, April 30). Scientific American. https://www.scientificamerican.com/article/experts-ice-spikes/

| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from |
| 0:05.0 | Curiosity.com. I'm Cody Gough, and I'm Ashley Hamer. Today you learn about how |
| 0:09.8 | early birds adjust to time changes faster than night owls, |
| 0:13.5 | and what you can do to slow the loss of jungles |
| 0:16.3 | with archaeologist Patrick Roberts. |
| 0:18.8 | We'll also answer a listener question |
| 0:20.3 | about why ice cubes grow spikes. But satisfy some curiosity. |
| 0:26.0 | This Sunday, everyone in the United States gets an extra hour of sleep |
| 0:30.0 | as daylight saving time comes to an end. |
| 0:33.0 | But that's only because we all lost an hour of sleep when it began back in March. |
| 0:38.0 | That's never easy, but new research shows that some people take it a lot harder than others. |
| 0:44.7 | I'm looking at you, Night owls. |
| 0:47.0 | Cody, specifically. |
| 0:49.3 | Hey, that's me! |
| 0:50.8 | Wait, this is bad. I don't like this. |
| 0:54.0 | Yeah, yeah, it's not good. |
| 0:56.0 | Researchers have been ragging on daylight saving time for years. |
| 1:00.0 | It apparently causes rates of heart attacks, |
| 1:02.8 | traffic accidents, and workplace injuries to spike. |
| 1:05.8 | But it turns out the shift affects people differently |
| 1:09.0 | depending on what researchers call their chronotype. Scientists have found connections between a person's sleep patterns and certain details of their DNA. |
| 1:18.0 | That means scientists can look at a person's genome and make a pretty good guess as to whether they're an early bird |
