NASA spent years and billions of dollars collecting Martian samples to bring home. But Congress's current proposed budget for the agency would leave them stranded. What's at stake? Take a deep dive with this recent feature:

microchromosome regions always tend to be mainly located in the nuclear interior, while macrochromosome derived region near the nuclear periphery. That is the chromosome rearrangements are constrained by their ancestral 3D locations in the nucleus

This is the Sunburst Candy Spider from Thailand. Not AI (sucks to have to declare this). Very real and had been on my wish list for a long time.

The taxonomic placement is unclear, so we are leaving it at Cyrtarachninae.

Our whitepaper on #ProjectPsyche is online now in @cp-trendsecolevo.bsky.social! Psyche will generate reference genomes for all European butterflies. Just imagine what we’ll be able to learn from them. And if you can’t quite imagine it, have a look at the piece. :)

How do new centromeres evolve while staying compatible with the division machinery?

Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.
