Clearly the aliens are monitoring the ArXiv and when Loeb's paper went up, they went "Oh shit, forgot to fire up the coma machine!" and it took a bit to warm up, and their response to the paper proves that they are superintelligent aliens with advanced tech.

This $100 Muon Detector Lets You Harness the Cosmos Uncover hidden mine shafts and more

The Discovery Dish is really neat: might I also suggest a low-cost muon detector per my colleague and citizen scientist Dave Schneider? :) spectrum.ieee.org/diy-muon-tom...

Fidonet is like the Neanderthals: once assumed to be a separate species and completely extinct, analysis reveals still living traces deep in the cyberome.

A black and white photograph of a long building corridor lit by fluorescent lights with a tile floor. The corridor is so long the end almost vanishes into the distance. Doors line both walls and the corridor is empty save for a tiny figure that can just be made out near the far end.

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

A photograph of a city intersection at night: towering bright screens on the surrounding buildings illuminate crowds filling the streets below. Some members of the crowd are motion blurred while others are sharply distince.

There's a neat book called "The Saucer Fleet" that looks at the spacecraft in classic movies like Forbidden Planet and This Island Earth, and heroically tries to match up the interior sets with the exteriors and its pretty clear the different design departments didn't feel much need to coordinate :)
