I always thought preschoolers were too egocentric to do well on communication tasks where they had to talk about novel referents. Old papers reported they'd say stuff like "this one looks like my uncle's hat."

@vboyce.bsky.social shows that this is wrong!

We’ve proven machines can learn to use language, but it took brute force to get there.

Meanwhile, animal communication evolved over millions of years under real-world constraints, shaping systems that are adaptable and efficient.

What can #AI learn from nature? 🧠

Evidence for representation of pretend objects by Kanzi, a language-trained bonobo Secondary representations enable our minds to depart from the here-and-now and generate imaginary, hypothetical, or alternate possibilities that are decoupled from reality, supporting many of our rich...

“Our findings suggest the capacity to form secondary representations of pretend objects is within the cognitive potential of, at least, an enculturated ape & likely dates back 6-9 million years, to our common evolutionary ancestors.” Amalia Bastos & @chriskrupenye.bsky.social today in @science.org.🧪

Could sometimes be a lack of understanding of what science is or how it works rather than a conscious anti science stance. Although it does lead to the same outcome at the end.

Publication bias is bad, sure.
But has anyone studied publication bias in studies on publication bias?

The urgent need for African research collaboration on medicine quality - Nature Communications Substandard and falsified medicines are a global health threat. The fight against them is a regulatory and research challenge; here, the authors argue the importance of global and regional oversight, monitoring of, and research into the extent of the issue.

They have studied the age at which chimpanzees take the most risks (jumping and doing crazy things from tree to tree). It turns out that they have a peak in childhood, and it decreases as they grow older. This tells us something very interesting about ourselves.

Great book about what understanding means in science. Highly recommend it.
Amazing historical account of cases studies in physics but applies to physical sciences more broadly.
Slow/repetitive at times but lots of gems if you stick with it.
