there comes a time
when poems don't rhyme
and free verse has its day

i really like th poems i write
when they come out that way

AI spots 'ghost' signatures of ancient life on Earth [via Science.org] 🧪⚗️🤖🧠👀🧬

"AI that can identify signs of ancient life in rocks of unknown provenance, based only on the pattern of chemicals left behind as biomolecules degrade over eons."

Being multilingual es bueno para el cerebro
The ability to speak more than one language might slow brain ageing and protect against cognitive decline. In a study of more than 80,000 people, researchers found that people who are multilingual are half as likely to show signs of accelerated ageing

assumptions:
x = x => x - x = 0
xy = yx
0x = x0 = 0
-------------------

1 -a(b-b) = 0
2 -ab -a(-b) = 0
3 ab = ab
4 0 -a(-b) = ab + 0 adding equation 3 to equation 2
5 -a(-b) = ab
conclusion: a negative times a negative equals a positive :-)

AI’s war on white-collar jobs may not end well. Past innovations boosted demand for educated, well-paid workers. By automating cognitive work, AI could reverse that trend — and history shows an alienated elite is social dynamite.

rattlesnakes will die if they are injected with enough of their own venom. They manage their own toxicity by storing their venom in a specialized gland and using proteins to block its effects.
The blood of ground squirrels contains similar proteins to protect them against rattlesnake bites DNKT

In the 1850s, the combined biomass of wild mammals was roughly equal to that of humanity plus its domesticated mammals. Since then, the populations of people and our domesticated mammals have grown rapidly, whereas the total biomass of wild mammals decreased by more than two-fold.
