Chicken-powered nukes, lab-grown mini brains and the thalidomide-blocking badass - A Little Bit Of Science | Lyssna här

This week’s line-up is a perfect reminder that science is not a neat little march of progress. It’s more like a grab bag where you pull out “chicken-powered nuclear landmines”, “mini brains that can sense time”, “one woman quietly preventing a medical catastrophe” and a misinformation spiral about circumcision and autism, all in the same episode.

During the Cold War, the British came up with a plan called ‘Operation Blue Peacock’, which involved burying atomic landmines in West Germany as a deterrent against a Soviet invasion. The problem was winter. Electronics and trigger mechanisms don’t love freezing temperatures and someone needed a way to keep the bomb warm enough to function. So the proposed solution was… chickens. As in, live poultry being placed inside the casing as biological heaters.

Then we jump to the present, where in a Matrix-like manoeuvre, scientists are growing “mini brain organoids” that model some aspects of human brain development. Recent work suggests these organoids can “record” the passage of time, in the sense that their activity changes in ways that reflect time-based patterns.

Following that, we hit one of those headlines that makes you blink twice: “Male circumcision doesn’t raise autism risk.” Which immediately raises the more important question, who decided that was a thing we needed to debunk in the first place? Thanks RFK Jr. The logic was basically “circumcision rates equal painkiller exposure”, which is a pretty heroic leap when you’re talking about something as complex as autism.

Lastly, in the middle of that era, Frances Kelsey, working at the FDA, refused to approve thalidomide in the United States without stronger evidence of safety, and her insistence on proper data prevented enormous harm. It’s a story of someone doing their job with a level of rigour that the system desperately needed.

So that’s the week: nuclear deterrence warmed by chickens, mini brains that make us argue about ethics and language, a reminder that real heroism can look like paperwork, and a misinformation case study where a speculative idea got treated like a fact.
