Why heat waves disproportionately impact minorities in US cities, and the researcher that critiqued his whole career on Twitter.
In this episode:
00:45 How heat waves kill unequally
Researchers are beginning to unpick how historic discrimination in city planning is making the recent heat waves in North America more deadly for some than others.
11:59 Research Highlights
A graphene layer can protect paintings from age, and a new and endangered species of ‘fairy lantern’.
Research Highlight: A graphene cloak keeps artworks’ colours ageles
Research Highlight: Newfound ‘fairy lantern’ could soon be snuffed out forever
When researcher Nick Holmes decided to criticise his past papers, in 57 tweets, he found the reflection enlightening. Now he’s encouraging other researchers to self-criticise, to help speed scientific progress.
20:53 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, Richard Branson’s commercial space flight, and the Maori perspective on Antarctic conservation.

How current and future ice loss in Greenland compares to the past, Long-Covid, and using graphene to make ultra-sensitive radiation detectors.
In this episode:
00:45 Greenland’s historic ice loss
Climate change is accelerating the loss of ice and glaciers around the world leading to unprecedented levels of disappearance. Researchers have drilled samples from deep in the Greenland ice sheet, to model how current, and future, losses compare to those seen in the last 12,000 years.

A robot defeats humans at yet another sport, and extreme diving in Cuvier’s beaked whales. Research Highlight: A robot triumphs in a curling match against elite humans; Research Highlight: A smiling whale makes a record deep dive
21:20 A radiation detector made of graphene
Radiation-detectors known as bolometers are vital instruments in many fields of science. This week, two groups of researchers have harnessed graphene to make super sensitive bolometers that could be used to improve quantum computers, or detect subtle traces of molecules on other planets. Research Article: Lee et al.; Research Article: Kokkoniemi et al.
27:49 Briefing Chat
We discuss some of the latest stories highlighted in the Nature Briefing. This week we chat about the lack of diversity in academia, and an animal ally that can protect wildlife during forest fires. Nature Careers: Diversity in science: next steps for research group leaders; National Geographic:
Probing the superconducting properties of graphene and a bacteria that can use manganese to grow. If you sandwich two sheets of graphene together and twist one in just the right way, it can gain some superconducting properties. Now, physicists have added another material to this sandwich which stabilises that superconductivity, a result that may complicate physicists’ understanding of magic angles.
With evidence mounting that SARS-CoV2 can spread in tiny aerosolized droplets, researchers have called on the WHO to change their guidance for disease prevention.

Repairing human lungs by hooking them up to pigs, and a new form of carbon. Research Highlight: How to use a live pig to revitalize a human lung; Research Highlight: This material is almost as hard as diamond — but as light as graphite
21:46 Manganese munchers
For decades it’s been thought that microbes that use manganese as an energy source must exist. Now, for the first time, researchers have found evidence that they do. Research Article: Yu and Leadbetter
29:12 Briefing Chat
We take a look at some highlights from the Nature Briefing. This time we discuss DNA evidence of contact between ancient Native Americans and Polynesians, reintroduction of bison to the UK, and the first extinction of a modern marine fish. Nature News: Ancient voyage carried Native Americans’ DNA to remote Pacific islands; The Guardian: Wild bison to return to UK for first time in 6,000 years; Scientific American:
