Contributing Correspondent Michael Price joins host Sarah Crespi to discuss the newest Mars analog to be built on the location of the first attempt at a large-scale sealed habitat, Biosphere 2 in Arizona.
Next, William Brady, a postdoctoral researcher in the psychology department at Yale University, talks with Sarah about using an algorithm to measure increasing expressions of moral outrage on social media platforms.

A team is creating bespoke words for scientific terms in African languages, and the sustainability of the electric car boom.
00:46 Creating new words for scientific terms
Many words that are common to science have never been written in some African languages, or speakers struggle to agree what the right term is. Now a new project aims to change that, by translating 180 research papers into six languages spoken by millions of people across the continent of Africa.

13:58 How sustainable is the electric car boom?
As electric cars become more ubiquitous, manufacturers will have to up the production of batteries needed to power them. But that begs the question – can they be mass produced in a sustainable way?

24:06 Briefing chat
We discuss some highlights from the Nature Briefing. This time, how a tusk-based ‘chemical GPS’ revealed details of a mammoth’s enormous journeys , and why the Perseverance rover’s first efforts to collect a Mars rock sample didn’t go according to plan.
Nature: Mammoth’s epic travels preserved in tusk
Nature: Why NASA’s Mars rover failed to collect its first rock core
A woolly mammoth that roamed Alaska 17,000 years ago covered enough ground in its 28-year lifetime to nearly circle the globe twice, an analysis of one of its tusks suggests.
Charles Piller, an investigative journalist for Science, talks with host Sarah Crespi about a risky trial of vitamin D in asthmatic children that has caused a lot of concern among ethicists.
They also discuss how the vitamin D trial connects with a possibly dangerous push to compare new treatments with placebos instead of standard-of-care treatments in clinical trials.
Next, Birhanu Eshete, professor of computer and information science at the University of Michigan, Dearborn, talks with producer Joel Goldberg about the risks of exposing machine learning algorithms online—risks such as the reverse engineering of training data to access proprietary information or even patient data.
