'You'll choke too' - an aerial embroidery landscape inspired by all the wildfires happening right now... I'm upset every time I smell smoke outside and somehow we have people starting them maliciously too! But we all breathe the same air so they'll choke too (1/2 - see thread for close-ups)

An embroidery hoop containing a sewn landscape from above. It shows a forest on the right, a line of fire and charred ground with smoke on the left. The smoke is felted wool.

Wow!!! "To investigate how these seemingly conflicting demands are resolved, we have carried out volume electron microscopy based reconstructions of the head direction circuits in the central complex of four species of bees and ants."

Deep conservation of head direction circuits in bees, ants and flies

To navigate, animal brains must continuously estimate the body's heading in space and compare it with internal goals to guide movement. In the fruit fly Drosophila melanogaster a neural circuit in the...

This paper from Shadmehr and colleagues looks amazing. "Thus, the climbing fibers solved the credit assignment problem by providing the gradient of a loss function with respect to the output of their individual P-cells."

Climbing fibers encode the gradient of a loss function for the cerebellum

Neurons in the brain are often many synapses away from motoneurons, yet if a movement results in error, each distant neuron needs a teacher that considers its specific contribution to production of th...

Here in Genova, visiting the group of our wonderful collaborator Agnese Seminara for science. Trying to learn about poets from here. Here's "The Wall" by Eugenio Montale, the 1975 Nobel Laureate (born in Genova, but seems to have chosen Milano for the latter & significant part of his life). #poetry

Excited to be in Trieste again for a week (visiting @ictp.bsky.social). Knew well the city's literary connections to Joyce and Svevo, but discovering Umberto Saba now. Here's his ambivalent poem about his hometown, translated by Geoffrey Brock. "Trieste has a sullen grace"
