Summary
This week, a speedy, yet simple switch, and a video-based AI helps assess heart health.
In this episode:
01:57 Speedy switches
Researchers have developed an ultra-fast electrical switch that they hope can be used in communication and imaging applications. Research Article: Nikoo et al.
08:14 Research Highlights
Using sound to estimate glacial retreat, and building a dodgier drone. Research Highlight: Underwater microphones listen as as glacier retreats; Research article: Falanga et al.
10:32 Algorithmic heart diagnosis
Scientists have developed a new algorithm which calculates the amount of blood pumped by the heart beat by beat. Research Article: Ouyang et al.; News and Views: AI tracks a beating heart’s function over time

| 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. |
| 0:25.6 | Welcome back to the nature podcast. This week, super quick computer switches. |
| 0:28.6 | And a new algorithmic way to measure heart health. |
| 0:32.6 | I'm Nick Al. |
| 0:33.6 | And I'm Charminany Bundell. |
| 0:51.1 | So listeners, as you may know, we are all working from home at the moment due to the coronavirus outbreak. |
| 0:55.9 | So that might be why things sound slightly different. For instance, I'm currently in a pillar fort recording this. Charmany, where are you coming to me from? Oh, mine's one step up |
| 1:01.3 | from that is actually a sofa cushion fort. It was carefully constructed by, well, initially by me, |
| 1:07.8 | and then it fell down on my flatmate who's an engineer had to come in and rescue me and explain how, you know, buildings work. |
| 1:15.6 | How buildings work. |
| 1:17.6 | When they're made of sofa cushions. |
| 1:19.4 | She made it stable, is the important point. |
| 1:21.3 | I now have a structurally stable sofa cushion studio so that I can record these lovely podcast links. |
| 1:26.5 | Well, as long as it's structurally stable |
| 1:28.4 | enough that you manage to get through the rest of the show with me, I think it would be good. |
