Origin and Early Evolution of Squamates and Their Kin: From Fossils to Genomes | Annual Reviews
Squamates (lizards, including snakes) are the most diverse group of terrestrial vertebrates on Earth today and have an evolutionary history dating back to at least the Middle Triassic (ca. 242 Mya). D...

I am excited to finally share our work on avian left/right symmetry breaking with you. We reveal a tissue-scale active torque dipole generated at the Hensen’s node, thanks to crazy experiments by Julia @juliapfanzelter.bsky.social and some analysis by me.

An active torque dipole across tissue layers drives avian left-right symmetry breaking
Unlike in mice, frogs, and fish, left-right (L/R) body axis formation in avian embryos does not arise from the chiral beat of cilia. Instead, a counter-clockwise tissue rotation around Hensen′ node, t...

Foundations: please step up and take over the Biodiversity Heritage Library (BHL). This is an absolutely essential scanned archive of all of the old journals and books from the 1500s to about 1920. Has been indispensable for my research.

We do something similar, but with Falcon tubes. The bases have the tube’s cap glued into them and fit on Xradia scanner chucks. The Falcon tubes themselves can then be screwed onto the whole contraption, making switching out tube-mounted samples quick & easy
