Wood you believe that it’s all about trees on the latest episode of The Reality Check podcast? Here are two classic segments about trees. First up is an interview with tree expert Owen Clarkin who gets to the root of many tree facts. That segment may have planted the seeds for a future segment so we leave you with Pat who looks into claims that the Amazon rainforest is the Earth’s lungs.

It’s a different kind of show this week as Darren and Adam discuss the recently released Superman film. The movie, directed by James Gunn, stars David Corenswet as Superman. The discussion includes a look at box office results and factors contributing to them, criticism of art and the various things we like and dislike about the film. Though it isn’t a particularly sciencey topic, we can’t help but apply our own brand of critical thinking to some aspects of the film.

The film is currently in theatres worldwide and available to purchase digitally. It’s recommended that you watch it before listening to this episode as there are plenty of spoilers, if you care about that kind of thing.

Is AI making us dumber? Darren looks into a recent study, which spawned some less than great press coverage, trying to assess where or not using LLMs is making us less intelligent. We didn’t really come to very good conclusions because we’ve been using too much AI. Adam gives an overview of mentalism, inspired by some recent podcast appearances by Oz Pearlman which have gone viral and brought some mainstream attention to this practice.

Could it be that dire wolves are no longer extinct? Researchers at Colossal Biosciences claim to have accomplished de-extinction of these long extinct wolves. Adam looks at the authenticity of their claims and examines what exactly they did to create these so called dire wolves.

Sadly, we recently got the news that our friend and frequent TRC contributor Dr. Stuart Farrimond passed away. Stuart was a medical doctor who had a brain cancer diagnosis at age 25. His treatment and side effects meant he had to stop practicing medicine. Stu reinvented himself as a food science expert - appearing on countless television and radio shows. He later became a best selling author of science education books. He will be missed.

Who would win in a fight, 100 men or 1 gorilla? If you’re thinking that question is too vague then you’ll love Darren’s analysis of the situation. Adam looks at claims that we’ve found evidence of alien life on an exoplanet called K2-18B. I’m not saying it’s aliens but… listen to the episode to find out!

The Telepathy Tapes is a popular podcast that tells the story of non verbal people showing evidence of psychic abilities and logging on to a psychic virtual chat room called The Hill.

What are they doing and what could this mean for the future of Artificial Intelligence?
