What roots the animal tree of life — the sponge, or the comb jelly? HHMI Investigator Nicole King & her team used a new method to answer an old question, & their results offer strong evidence that sponges may have evolved first. hhmi.news/3M2JkbG

The world’s “most dangerous animal” just got easier to study 🦟 HHMI’s @leslievosshall.bsky.social & #VosshallLab at @rockefeller.edu have built the 1st cellular atlas of Aedes aegypti, mapping everything from legs to antennae. Available now to all researchers, & the public: bit.ly/4oO4MzB

The first detailed look at how mosquitoes mate from @leslievosshall.bsky.social's lab reverses the assumption that male mosquitoes control the process, finding that a subtle female behavior dictates whether mating will take place or not. @currentbiology.bsky.social More here: https://bit.ly/4huwEpL

This fiery mixture of red and green neurons in the brain of a mouse shows how interconnected different types of neurons can be. Shown in green are the excitatory pyramidal neurons, and in red are inhibitory interneurons. Credit: Nelson Spruston and Erik Bloss, @hhmijanelia.bsky.social

🖥️ STIM, a new tool developed at Janelia & @mdc-berlin.bsky.social‬, aligns sections of irregularly spaced 2D spatial transcriptomics data & renders them as images to reconstruct 3D volumes of gene expression, allowing researchers to see how all genes are expressed & organized in 3D tissue. 🧬

The spore, the merrier. 🌿 This image shows a cross section through the reproductive region of a fern (Ceratopteris richardii), revealing its intricate internal structures. The blue and purple ovals are spores, which ferns use to reproduce and spread.
