Summary

These days about half of the protein the world’s population eats is from seafood. Staff Writer Erik Stokstad joins host Sarah Crespi to talk about how brand-new biotech and old-fashion breeding programs are helping keep up with demand, by expanding where we can farm fish and how fast we can grow them. Sarah also spoke with Jan Claesen, an assistant professor at the Cleveland Clinic’s Lerner Research Institute, about skin microbes that use their own antibiotic to fight off harmful bacteria. Understanding the microbes native to our skin and the molecules they produce could lead to treatments for skin disorders such as atopic dermatitis and acne. Finally, in a segment sponsored by MilliporeSigma, Science’s Custom Publishing Director and Senior Editor, Sean Sanders, talks with Timothy Cernak, an Assistant Professor of Medicinal Chemistry and Chemistry at University of Michigan, Ann Arbor, about retrosynthesis—the process of starting with a known chemical final product and figuring out how to make that molecule efficiently from available pieces. This week’s episode was produced with help from Podigy.

0:36.7	Do we really need another computer? One that's faster,
0:39.9	more powerful. Not everyone does. But to reinvent music using a neural processor, work off the grid
0:45.4	with all-day battery, or bring your vision to life with AI-powered co-creator, then a copilot plus PC
0:50.8	can make a difference. A powerful AI computer is not for everyone. But if you're
0:55.4	trying to change the world, even if just your own, we built one for you. Microsoft Copilot Plus

1:16.7	I'm Sarah Crespi.
1:18.0	Each week we feature the most interesting news and research published in science and the sister journals.
1:23.0	First up, I talk with staff writer, Eric Stockstead, about fish farming's future, from giant offshore farms
1:29.8	to breeding boneless fish. I also talk with researcher Jan Klossin about skin microbes that
1:35.6	use their own antibiotic to fight off harmful bacteria. Finally, we have a sponsored segment from
1:41.3	Milipur Sigma and our Custom Publishing Group. The director and senior editor of custom publishing, Sean Sanders, interviews chemical synthesis
1:48.2	and data science researcher, Timothy Sernak, on the topic of retro synthesis.
1:54.6	Now we have staff writer Eric Stockstead.
1:57.4	He wrote a feature on the modernization of fish breeding in this week's issue. Hi, Eric.
