Summary
This week, uncovering the structure of materials with useful properties, and quantum entanglement over long distances.
In this episode:
00:45 Analysing Prussian blues
Analogues of the paint pigment Prussian blue are used in a variety of chemical processes. Now, researchers have uncovered their atomic structure. Research Article: Simonov et al.; News and Views: Ordered absences observed in porous framework materials
08:17 Research Highlights
Teenagers’ natural sleep cycles impact on academic performance, and an extinct, giant rodent with a surprisingly tiny brain. Research Highlight: A teenager’s body clock can ring in school success; Research Highlight: Giant extinct rodent was all brawn and little brain
10:49 Distant entanglement
Researchers have demonstrated quantum entanglement between two points separated by 50 km of fibre optic cables. Research Article: Yu et al.
17:17 News Chat
The latest on the coronavirus outbreak, and gene editing gets an upgrade. News: Coronavirus: latest news on spreading infection; News: Super-precise CRISPR tool enhanced by enzyme engineering

| 0:00.0 | Nature. |
| 0:02.0 | In an experiment, I don't know yet. |
| 0:06.0 | Why is Blight so far? |
| 0:08.0 | Like, it sounds so simple. |
| 0:09.0 | They had no idea. |
| 0:11.0 | But now the data's... |
| 0:12.0 | I find this not only refreshing, but at some level astounding. |
| 0:20.0 | Nature. |
| 0:25.7 | Welcome back to the nature podcast. |
| 0:29.2 | This week, working towards a quantum internet. |
| 0:32.0 | And the pigment posing a chemical puzzle. |
| 0:33.2 | I'm Nick Al. |
| 0:34.8 | And I'm Charmoney Bundell. |
| 0:48.3 | First up on the show, let's talk about painting. |
| 0:52.3 | Now, don't worry, this is still the Nature podcast. |
| 0:55.5 | I've not started my spin-off art show yet. |
| 1:02.4 | But I do want to talk to you about a particular shade of deep blue, Prussian blue in fact. |
| 1:08.2 | It's been used for centuries for all sorts of applications, from art to medicine. |
| 1:12.2 | For example, it can be used to treat people who have heavy metal poisoning by soaking up the toxins. |
| 1:14.9 | And it's not just Prussian Blue itself that has proven useful. |
| 1:18.7 | Prussian Blue analogues, materials with similar but not identical structures, |
| 1:24.2 | have even more uses, such as decontaminating radioactive materials, acting as |
