A whiteboard covered over with many layers of black and red pan scribbles, including some mathematical and Greek letters

Latest in “The Unerased Whiteboards of UCL” series… now this is a classic example of insufficient erasure leading to multiple sedimentary layers of thought – my personal favourite sort of whiteboard residue.

Also resembles something you might see in the Tate Modern.

Molecular basis for de novo thymus regeneration in a vertebrate, the axolotl The molecular, cellular, and functional restoration of the axolotl thymus after de novo regeneration is described.

Happy to share the first paper from my journey at @psich.bsky.social towards X-ray connectomics, now out in @natmethods.nature.com: www.nature.com/articles/s41...

Hmm, I must have the same thing….

Congratulations Berta!

Evolution of taste processing shifts dietary preference - Nature Calcium imaging of taste neurons and the ventral brain provides insight into evolutionary divergence of food choice in Drosophila species, supporting a role of sensorimotor processing in addition to p...

Thrilled to share our new paper!
With @tomtom-auer.bsky.social team, we asked how #evolution reshapes what animals #eat to match their ecological niches. Using pan-neuronal Ca2+ imaging, we show that the changes are in how the brain processes #taste.

New research from EMBL and @Stanford shows how centromeres retain their function despite their rapid rate of change, and the evolutionary constraints that govern this process.

An archaeal genetic code with all TAG codons as pyrrolysine Multiple genetic codes developed during the evolution of eukaryotes and bacteria, yet no alternative genetic code is known for archaea. We used proteomics to confirm our prediction that certain archae...

Some archaea—an ancient group of microorganisms—have an entirely novel genetic code, according to a new study in Science.

The findings expand our understanding of how alternative genetic codes evolve and hint at new molecular tools for biotechnology applications. https://scim.ag/4omApQ7

Chirality is known to be important for the movement of microorganisms and active matter. In our new paper out today in @natphys.nature.com, we show that chirality is used by malaria parasites to control their motion patterns:

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.

It ships many new features, detailed below, but that are articulated around the following:

Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.
