In the 1980s, San Francisco hairdresser Maurice Cohen used static electricity to give his clients shocking ’dos. The technique and style didn’t catch on, but our fascination with static electricity—which, incidentally, is still not fully understood by physicists—is still going strong.

The consensus for >40 y has been that the number of insect species on Earth ~6,000,000. Using genetic information for 1.6 million individual insects, it is now conservatively estimated that the true number of insect species is at least 14 to 20 million. www.pnas.org/doi/10.1073/...

Wrong! @sciam.bsky.social claims that Earth's fungal hyphae in the topsoil (110 quadrillion km or ~12,000 light years) is enough to cover the distance from earth to Proxima Centauri and back. Well, the distance is 4.25 light-years. So the fungal hyphae will suffice for more than 1411 such trips.
