Kelp locks up millions of tonnes of carbon globally, provides a nursery for fish and is a buffer against coastal flooding. But climate change, weather and fishing are taking their toll. Now, Mika Peck and his team at the University of Sussex are monitoring kelp off the south coast of the UK, to see if it can recover from the damage done to it by trawling and help improve biodiversity in the area.

Science: Gun Violence Research Returns, Pikas In Winter & Glass Sponges
Funding for gun violence research in the US returns after a 20-year federal hiatus, and the glass sponges that can manipulate ocean currents.
In this episode:
00:45 Gun violence research is rebooted
For 20 years there has been no federally-funded research on gun violence in the US. In 2019, $25 million a year was allocated for this work. We speak to some of the researchers that are using these funds, and the questions they are trying to answer about gun violence.

09:21 Research Highlights
Strategic laziness and yak dung help pikas survive harsh winters, and how food gets wasted in China’s supply chains.

11:40 How a sea sponge controls ocean currents
Venus’ flower baskets are marine sponges that live at the bottom of the Pacific Ocean. These sponges have an unusual glass skeleton that helps them gather food, and even appears to control ocean currents.

NASA Space Missions: The Search For Life On Venus
NASA is planning two missions to Venus to assess if the now-toxic planet once had an ocean, continents and life. Scientists are beginning the effort on Earth by training sensors and machine learning systems to analyze the building blocks of our own planet. Photo illustration: Laura Kammermann
Science: Race-Based Medicine, Space Tourism & Western U.S. Heatwave
Race-based medical practises are being challenged more and more, as it becomes increasingly clear they have little basis in science.
The team finds out why adjustments for race and ethnicity are still being made in medicine, despite the potential harm and healthcare implications they cause. It’s been a massive week for the future of space tourism – the team shares a clip of a very excited Richard Branson who’s recent journey into microgravity has set the stage for the launch of Virgin Galactic’s first commercial space flights. The team gives an update on the dramatic heatwave ravaging the US, as more record high temperatures are set, continuing to leave destruction in its wake. They also explain what ‘impact gardening’ is and why it might help us find alien life on Jupiter’s moon Europa, and they share important news on the state of the cosmetics industry in Neolithic times. On the pod are Rowan Hooper, Chelsea Whyte, and Layal Liverpool.

14:25 Self-criticism
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.

Science: Avoiding Sudden Food Scarcity, Lattice Strength, Time Neurons
Addressing the problem of sudden food scarcity in US cities, and the up-and-coming field of computational social science.
In this episode:
00:45 Food shocks
Climate change, the COVID-19 pandemic, and geopolitical crises can cause food shortages. To tackle this issue, Alfonso Mejia and colleagues have modelled how to best mitigate these food shocks in US cities. Alfonso tells us about the new analyses and what steps cities could take in the future.
