Weekend #Plankton Factoid 🦠🦐
Most cladocerans have a bivalve carapace, but one genus is very different. Leptodora is globally distributed in the north, large (~2 cm), elongated, and effectively transparent, leading it to be coined "ghost flea" by a colleague. It is a primitive genus and is the only cladoceran with a nauplius stage. Highly predaceous with a huge eye, it preys on juv…

A scale bar of 200 microns gives the size of the eyespot, and makes clear how large this organism is.

The painter Henri Rousseau
(1844–1910)
famously never left France;
He concocted his fantastical jungles from visits to the botanical gardens in Paris,
images in books and taxidermized specimens in natural history museums,
and a teeming visual imagination.
The results are on view in a mesmerizing exhibition,
“Henri Rousseau: A Painter’s Secrets,”
at the Barnes Foundation in Philadelphia until Feb. 22.
These works haven’t been assembled …

The pilot aims to enhance officer and public safety by identifying individuals flagged for a history of serious offenses. However, critics worry about societal risks and the lack of public debate. Axon CEO Rick Smi…

Repetition suppression for mirror images of objects and not Braille letters in the ventral visual stream of congenitally blind individuals eneuro.org/content/early/2025/

Repetition suppression for mirror images of objects and not Braille letters in the ventral visual stream of congenitally blind individuals
Mirror-invariance is the cognitive tendency to perceive mirror-image objects as identical. Mirrored letters, however, are distinct orthographic units, and must be identified as different; mirror-invariance must be ‘broken’ to enable efficient reading. Consistent with this phenomenon, a small, localized region in the ventral visual stream, the Visual Word Form Area (VWFA), exhibits repetition suppression to both identical and mirror pairs of objects but only to identical, not mirror, pairs o…
