This week, my guest on Virtually Speaking Science was TIME health reporter Maia Szalavitz, who specializes in addiction, among other topics. We started by discussing the recent deaths of two young people at a club called Electric Zoo, the result of an apparent overdose of a drug called “Molly” — a form of Ecstasy, or MDMA, often cut with methylone, that also contributed to a string of club-related deaths earlier this year. It ended up being a fascinating discussion about the nature of addiction, misguided federal drug policy, and finding a middle ground between demonizing or glorifying powerful substances.

“[Scientists] have located the physical source of the teakettle whistle at the spout as steam flows up it, and identified a two-mechanism process of whistle production. Their results show that as the kettle starts to boil, the whistle behaves like a Helmholtz resonator — the same mechanism that causes an empty bottle to hum when you blow over the neck. However, above a particular flow speed, the sound is instead produced by small vortices — regions of swirling flow — which, at certain frequencies, can produce noise. The findings are potentially able to explain familiar problems of other wayward whistles, such as the annoying plumbing noises caused by air trapped in pipes or damaged car exhausts.”

Apparently flammable trousers are a “thing” in certain science subfields, beginning with the 2005 Ig Nobel Prize for agricultural history, awarded to James Watson of Massey University, New Zealand, for his study, concerning the period between World War I and World War II, called “The Significance of Mr. Richard Buckley’s Exploding Trousers.”
“For the process of removing the slack, it’s all done by feel. I have some pliers that I use to pull the cables tight and a pair of crimpers that I use to clamp copper sleeves down around the cables and hold them in place. I started out making a bunch of abstract sculptures with this method, so I got a lot of practice and a good feel for it before I went on to making practical things. The surprising part is, because there are so many cables, none of them has to be pulled that tight. If you push on any of them, it doesn’t feel like they’re under that much tension. It’s just that the added effect of them all creates a totally stable system. The cable is 1/16” galvanized steel wire rope.”
