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.

07:44 Coronapod
The COVID-19 pandemic has massively shifted the scientific landscape, changing research and funding priorities across the world. While this shift was necessary for the development of things like vaccines, there are concerns that the ‘covidization’ of research could have long-term impacts on other areas of research.

20:45 Research Highlights
The Hayabusa2 mission successfully delivers a tiny cargo of asteroid material back to Earth, and a team in China claims to have made the first definitive demonstration of computational ‘quantum advantage’.

22:38 Calculating carbon
Limiting carbon emissions is essential to tackling climate change. However, working out how to do this in a way that is fair to nations worldwide is notoriously difficult. Now, researchers have developed a model that gives some surprising insights in how to equitably limit carbon.

Radio News 24/7 reports: Russia rolls out its Sputnik vaccine, a 6-year Japanese space mission returns sample from an asteroid, and other top world news.

Staff Writer Meredith Wadman and host Sarah Crespi discuss what to expect from the two messenger RNA–based vaccines against COVID-19 that have recently released encouraging results from their phase III trials and the short-term side effects some recipients might see on the day of injection.
Sarah also talks with researcher Xing Chen, a project co-leader and postdoctoral scientist at the Netherlands Institute for Neuroscience, about using brain stimulation to restore vision. Researchers have known for about 70 years that electrical stimulation at certain points in the brain can lead to the appearance of a phosphene—a spot of light that appears not because there’s light there, but because of some other stimulation, like pressing on the eyeball. If electrical stimulation can make a little light appear, how about many lights? Can we think about phosphenes as pixels and draw a picture for the brain? How about a moving picture?
