Single-celled organism with no brain is capable of Pavlovian learning
A trumpet-shaped, single-celled organism seems able to predict one thing will follow another, hinting that such associative learning emerged long before multicellular nervous systems
This is an awesome discovery:
A single-celled organism with no brain called Stentor seems capable of Pavlovian learning. Yes, it can actually learn to associate two things despite having no neurons.

Galileoβs handwritten notes found in ancient astronomy text
Discovery sheds new light on how famed astronomer came to lead a scientific revolution
I love everything about this! The conviction that a major figure was not struck by a bolt of lightning but worked to understand the system he would ultimately critique and help dismantle. The scholarly sleuthing rare books β all of it. ππ€

I'm sorry. As a technology writer, I'm supposed to be telling you that this bet will some day pay off, because one day we will have shoveled so many words into the word-guessing program that it wakes up and learns how to actually do the jobs it is failing spectacularly at today. This is a proposition akin to the idea that if we keep breeding horses to run faster and faster, one of them will give birth to a locomotive. Humans possess intelligence, and machines do not. The difference between a human and a word-guessing program isn't how many words the human knows.
I'm sorry. I know that when we talk about "digital sovereignty," we're obliged to talk about how we can build more data-centres that we can fill up with money-losing chips from American silicon monopolists in the hopes of destroying as many jobs as possible while blowing through our clean energy goals and enshittifying as much of our potable water as possible.

As someone who comes from a country that this kind of 'private currency' (es.wikipedia.org/wiki/Fichas_...) were used until the 1920s, this is a HORRIBLE idea. The impacts of private currency were so horrible that we study about them in middle and high school. If not, read sub sole and sub terra

What the world can learn from Copenhagenβs cycling revolution
Close to two-thirds of the cityβs residents commute by bike to school or work every day.
βWhen mayors in other cities ask me how #Copenhagen afforded to invest in its cycling networks, I ask them how on earth they have been able to afford highway projects. We invested in bike lanes because that was the cheapest option.β
