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 retreatsResearch 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

Why is Blight so far?

Like, it sounds so simple.

They had no idea.

0:11.0

But now the data's...

I find this not only refreshing, but at some level astounding.

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.

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
