Measuring Earth ’s surface like never before, and the world’s fastest random number generator
First up, science journalist Julia Rosen talks with host Sarah Crespi about a growing fleet of radar satellites that will soon be able to detect minute rises and drops of Earth ’s surface—from a gently deflating volcano to a water-swollen field—on a daily basis.
Sarah also talks with Hui Cao, a professor of applied physics at Yale University, about a new way to generate enormous streams of random numbers faster than ever before, using a tiny laser that can fit on a computer chip.
This week’s episode was produced with help from Podigy.

A mammoth discovery: oldest DNA on record from million-year-old teeth
Researchers sequence the oldest DNA ever recovered, and the people bringing art and science together.In this episode:00:46 Million-year-old mammoth DNAThis week, researchers have smashed a long-standing record by sequencing a genome that's over a million years old. They achieved this feat by extracting DNA from permafrost-preserved mammoth teeth, using it to build-up a more detailed family tree for these ancient animals.Research Article: van der Valk et al.News: Million-year-old mammoth genomes shatter record for oldest ancient DNANews and Views: Million-year-old DNA provides a glimpse of mammoth evolution10:00 Research Hi...

Don ’t think too deeply about the origin of life – it may have started in puddles
How water chemistry is shifting researchers' thoughts on where life might have arisen, and a new model to tackle climate change equitably and economically.In this episode:00:46 A shallow start to life on Earth?It’s long been thought that life on Earth first appeared in the oceans. However, the chemical complexities involved in creating biopolymers in water has led some scientists to speculate that shallow pools on land were actually the most likely location for early life.News Feature: How the first life on Earth survived its biggest threat — water07:44 CoronapodThe COVID-19 pandemic has massively shifted the scientifi...

What we can learn from a mass of black hole mergers, and ecological insights from 30 years of Arctic animal movements
First up, host Sarah Crespi talks with Staff Writer Adrian Cho about new gravitational wave detections from the first half of 2019—including 37 new black hole mergers. With so many mergers now recorded, astrophysicists can do different kinds of research into things like how new pairs of black holes come to be and how often they merge.
Sarah also talks with Sarah Davidson, data curator at the Max Planck Institute of Animal Behavior, about results from an Arctic animal tracking project that includes 3 decades of location information on many species, from soaring golden eagles to baby caribou taking their first steps. ...

Taking the politicians out of tough policy decisions; the late, great works of Charles Turner; and the science of cooking
First up, host Sarah Crespi talks to News Intern Cathleen O’Grady about the growing use of citizens’ assemblies, or “minipublics,” to deliberate on tough policy questions like climate change and abortion. Can random groups of citizens do a better job forming policy than politicians?
Next, we feature the latest of a new series of insight pieces that revisit landmark Science papers. Sarah talks with Hiruni Samadi Galpayage Dona, a Ph.D. student at Queen Mary University of London, about Charles Turner, a Black zoologist who published multiple times in Science in the early 1900s. Despite being far ahead of his time in...

Superconductivity gets heated
A high pressure experiment reveals the world’s first room-temperature superconductor, and a method to target ecosystem restoration.In this episode:00:44 Room-temperature superconductivityFor decades, scientists have been searching for a material that superconducts at room temperature. This week, researchers show a material that appears to do so, but only under pressures close to those at the centre of the planet. Research Article: Snider et al.; News: First room-temperature superconductor puzzles physicists 08:26 CoronapodThe Coronapod team revisit mask-use. Does public use really control the virus? And how much evidence...
