You can call it the “revenge of the computer scientist.” An algorithm that made headlines for mastering the notoriously difficult Atari 2600 game Montezuma’s Revenge can now beat more games, achieving near perfect scores, and help robots explore real-world environments. Pakinam Amer reports.

It is the wood that the rock greats have sworn by—swamp ash, in the form of their Fender Telecaster and Stratocaster guitars—for more than 70 years. If you have ever listened to rock, you have probably heard a solid-body swamp ash guitar. But now climate change is threatening the wood that helped build rock and roll.

In today’s podcast, veteran guitarist Jim Campilongo takes us through the finer points of swamp ash and what it would mean to lose it. 

Bonus material: Here’s Campilongo showing the difference between the sound of a solid-body swamp ash guitar and a hollow-body one. 

And here’s a little information about Campilongo’s latest project: He teams up with his longtime collaborator Luca Benedetti on the album Two Guitars. Check it out.

Editor’s Not (2/16/21): This podcast incorrectly stated that the article on climate change and swamp ash in the February 2021 edition of Scientific American was authored by Priyanka Runwal and Andrea Thompson. The author was Runwal alone.

Today on the Science Talk podcast, Alexis Gambis, a New York University biologist and independent filmmaker, speaks about making Son of Monarchs, which won the 2021 Alfred P. Sloan Feature Film Prize at the Sundance Film Festival.

The film is about a Mexican scientist who studies the evolution of monarch butterfly wings. It is a cultural piece about the politics of immigration, spirituality and shifting identities.

Gambis talks about science beyond the lab bench, bringing CRISPR technology to the big screen and how he is usually given to bold, innovative features that focus on science or technology and that depict a scientist as a central character. 

In one scene in Son of Monarchs, the main character stands in a rowdy bar and raises his glass to “CRISPR and the genetic revolution.” There are several allusions throughout the film to how gene editing fascinates and terrifies us. Evolutionary science is the thread that ties the human story together. 

From script to screen, the scientist-director meditates on the long journey to the finish line, securing funding and how science’s big stories can be weaved into art. 

Gambis has been running a science film festival for 13 years and making science films for longer. His next project, El Beso, is a plunge into the life and science-fiction writings of Santiago Ramón y Cajal, an early 20th-century Spanish neuroscientist who won the 1906 Nobel Prize in Physiology or Medicine.
