Ancient Chinese legal texts describe cutting off a person’s nose as one of the “Five Punishments”, along with decapitation, limb amputation, castration and facial tattooing. A 700-year-old skeleton offers the first physical evidence of this practice. www.newscientist.com/article/2589...

Mice with half brain were given human brain organoids. What is less known is that in a reciprocal experiment, men with half brain were implanted with mouse brain organoids. The result was the Chi Phi frats at @Cornell. www.newscientist.com/article/2589...

#DEI? @stanforduniversity.bsky.social Stanford University used AI to alter picture. The White male student on the right was turned into a Black female, and the Asian female student on the left was slimmed and “beautified.” Beside the non-apology, was anyone fired? Too much to ask?

#NewToMe: Synchronous Dichogamy in Avocado flowers. Each individual flower contains both ♂ and ♀ parts. Flowers open twice over two days, functioning either as ♀ during the first phase and ♂ during the second phase or as ♂ during the first phase and ♀ during the second phase.

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.

Today, I am exactly as old as Charles Darwin was when he died: 26,729 days. Depressing how little I have achieved by comparison. On the other hand, at my age, Mozart was already dead for more than 37 years.

Females were cloned out of males. The feat was possible because males have all the chromosomes needed to make a female, but females lack one chromosome needed to make males. So, the the Genesis story of Eve and Adam's rib may be possible with CRISPR. www.newscientist.com/article/2585...
