International News Editor Martin Enserink talks with host Sarah Crespi about a moratorium on prion research after the fatal brain disease infected two lab workers in France, killing one.
Next, Abhay Goyal, a postdoctoral fellow at Georgetown University, talks with intern Claire Hogan about his Science Advances paper on figuring out how to reduce the massive carbon footprint of cement by looking at its molecular structure.
Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders interviews Ansuman Satpathy, assistant professor in the department of pathology at Stanford University School of Medicine and 2018 winner of the Michelson Prize for Human Immunology and Vaccine Research, about the importance of supporting early-career research and diversity in science, technology, engineering, and math. This segment is sponsored by Michelson Philanthropies.


Discoveries of mass graves of Indigenous children in Canada have prompted new scrutiny of the residential school system – including the role physicians played in unethical experiments, says paediatrician Samir Shaheen-Hussain

Killing fossil fuels to halt global warming is the greatest challenge we face. We now have a masterplan of what we must do when – and there’s no time to delay

People think using more energy is a bad thing, says International Energy Agency chief Fatih Birol – but as long as we can make it cleanly, it needn’t be

Satellite imaging has shown population increases are 10x higher in flood prone areas than previously thought, and a new way to introduce fairness into a democratic process.
In this episode:
00:47 Calculating how many people are at risk of floods.
Researchers have used satellite imagery to estimate the number of people living in flood-prone regions. They suggest that the percentage of people exposed to floods has increased 10 times more than previously thought, and with climate change that number is only set to climb.

People are happy to be selfish towards a crowd, but generous to an individual; and how wildfire smoke affects clouds’ brightness.
Research Highlight: ‘Robber’ experiment tests generosity — with sobering results
Research Highlight: Wildfire smoke creates brighter clouds — and weather changes
12:01 Making democracy fairer
Citizens’ assemblies are small groups of people invited to come together to help inform and affect policy decisions. But deciding who is in these groups is a mathematical challenge — the process needs to be random, but still reflect social demographics. This week, researchers describe a new algorithm that could offer a solution.

20:04 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, how ships could spread a deadly coral disease, and research shows that female scientists are less likely to be cited in elite medical journals.
The Guardian: Deadly coral disease sweeping Caribbean linked to water from ships
Nature News: Fewer citations for female authors of medical research
Most black-footed albatross nest on sandy beaches in Hawaii—but rising sea levels threaten their eggs and chicks. Researchers in Mexico and the United States came up with a way to save these birds: having young albatross hatch and imprint on an island 6000 kilometers away with higher ground. Watch to see the journey of these black-footed albatross. Read the story: https://www.sciencemag.org/news/2021/…
More than 50 countries around the world have pledged to become net zero. But what does net zero actually mean—and is it achievable?
First this week, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the paradox of metabolically healthy obesity. They chat about the latest research into the relationships between markers of metabolic health—such as glucose or cholesterol levels in the blood—and obesity. They aren’t as tied as you might think.
Next, Colin Dayan, professor of clinical diabetes and metabolism at Cardiff University and senior clinical researcher at the Wellcome Centre for Human Genetics at the University of Oxford, joins Sarah to discuss his contribution to a special issue on type 1 diabetes. In his review, Colin and colleagues lay out research into how type 1 diabetes can be detected early, delayed, and maybe even one day prevented. Finally, in the first of a six-patrt series of book interviews on race and science, guest host Angela Saini talks with author and professor of history at the University of Massachusetts, Amherst, Samuel Redman, about his book Bone Rooms: From Scientific Racism to Human Prehistory in Museums. The two discuss the legacy of human bone collecting and racism in museums today.
