This is a Scanning Electron Microscopy (SEM) picture that I took some years ago. Is the trachea (broken) of a tiny Ochyroceratidae spider. This finding makes me feel and enjoy how marvelous nature's architecture is!

Nobel laureates from the whole world are asking President Javier Milei from Argentina to STOP destroying SCIENCE in the country.

Daddy-longlegs were thought to have only one pair of eyes...until now 🤯! We report today in Current Biology that extant daddy-longlegs have additional vestigial eyes seen in four-eyed fossil relatives.
Vestigial organs, fossils and evodevo!!🌈

New paper from the lab! Highly dynamic evolution of the chemosensory system driven by gene gain and loss across subterranean beetles, spearhead by Pau Balart-García 🧬🪲🧬sciencedirect.com/science/articl…

Happy to be part of a paper on Ricinulei performed in the Gonzalo Giribet Lab Harvard Organismic & Evolutionary Biology Museum of Comparative Zoology and led by Shoyo Sato . This is the most comprehensive phylogenomic analysis of Ricinulei using UCEs and opens many windows for further research.
