3D-printing some of the world's lightest materials

A new way to produce aerogels opens up their use, and understanding how sulfur can change state between two liquids.

In this episode:

01:05 Printing aerogels

Aerogels are materials with impressive insulating properties, but they’re difficult to handle, due to their innate fragility. Now, researchers have shown a new way to 3D print the most common form of aerogel, opening up a range of potential new applications. Research Article: Zhao et al.

07:00 Coronapod

To provide targeted public health interventions during the pandemic, it’s vital that data are collected and shared effectively. We discuss the countries doing this well, and find out how fragmented systems are preventing epidemiologists from giving up-to-date information on outbreaks.

21:11 Research Highlights

Fats in the blood as a possible marker of autism, and the selfish component to solar panel adoption. Research Highlight: Fats in the blood linked to autism; Research Highlight: Self-interest powers decision to go solar

23:24 Liquid-liquid transitions

It’s been thought that some liquids may be able to exist in two distinct states, but evidence has been scarce. Now, researchers show that sulfur can exist in two liquid states, and have discovered some insights into how this might occur. Research Article: Henry et al.; Video: 24 hours in a synchrotron
