How does the space station never run out of oxygen? - Alvaro Romero-Calvo and Theo St Francis

Explore the incredible systems that create breathable air in space, and how we can adapt that process for future expeditions. -- For over 25 years, the International Space Station’s air supply systems have revolutionized space missions. Yet the need for regular maintenance, repairs, and upgrades has pushed engineers to develop even more reliable systems for future spacecraft. How do we create breathable air in space? And what does that look like for longer expeditions? Alvaro Romero-Calvo and Theo St Francis investigate. Lesson by Alvaro Romero-Calvo and Theo St Francis, directed by Lazy Chief.

Skeptics Guide #1095

The Skeptic’s Guide to the Universe Skepticast #1095 July 2nd 2026 Segment #1. Back to Basics What Is Scientific Skepticism I'm a long-time listener to your podcast, and I always listen to you when I commute to and from work - which is about a 45-minute drive in each direction. I believe I have a fairly good understanding of the scientific method, and I do believe I understand, and practice, a skeptical view of things regularly in life. I work as a correctional officer, and I find the skeptical principle very useful when I deal with inmates' often strongly biased views on many topics. I have recommended the show to a lot of friends and co-workers, and many have followed those recommendations. But, and this is the main point of this letter, I feel that many simply don't understand the basic concepts, the very foundation, of what you're doing. Terms like skepticism and your adherence to concepts like the scientific method are not that widely known, and I believe that could be easily remedied. I would suggest that you every now and then take some time on the show to explain these basic concepts to retain any new listeners, to make them up to speed with what the show is really about. I am aware of your recurring segment on cognitive bias, logical fallacies and the like (and I do appreciate it). But I feel those discussions require knowledge of the more basic concepts - which I find mostly omitted. I strongly believe your work is extremely important, probably more so in our bubble-ridden, AI-advised, TikTok-brainrot present. Especially, I'd guess, for U.S. listeners given the almost oppressive stance from your government on science in general. With that said, thank you so much for your hard work! When writing this I noticed I wasn't a Patreon member. So I remedied that. I can't access my private e-mail account from work, so I can't start a paid membership right now. I will though, as soon as my job stint is up this weekend. Best regards, Fredrik Granlund, Sweden Segment #2.

I Survived the Most Dangerous Heat on Earth (for Science)

It's getting hot in here… can we survive it? ↓↓↓ More info and sources below ↓↓↓ I pushed my body to the edge in a climate & sports research lab to discover what extreme heat really does to us. Why humidity, not just temperature, can make heat deadly, and how climate change and city design are making dangerous heat more common. Be Smart explores science questions you didn’t even know you wondered about. It is hosted and produced by Joe Hanson, PhD. We post new videos all the time, so please subscribe!
