This is my first blog post but I hope to contribute more in the future (about my work on dendrite maintenance in the Parrish laboratory). Today’s post is about the work I did prior to starting graduate school at UW.         Once upon a time I joined Amin Ghabrial's laboratory at the University of Pennsylvania as a technician. Before that, I honestly had not given much thought to tubes. I remember the first time a straw failed me (it had a hole in it), and I remember feeling rather betrayed. Luckily straws are replaceable; the tubes running through our bodies though are not, therefore we better learn about and take good care of the ones we have.
        Some of the most important tubes in the human body are the capillary tubes that allow for separation of blood and brain fluid (known as the blood-brain barrier). In Cerebral Cavernous Malformation, a hereditary disorder that causes migraines, seizures, and even stroke-induced death, this barrier is compromised as a result of dilated a…

‘Non-dinosaurian dinosauromorphs’ certainly has a poetic ring to it. It’s the name given to the phylogenetic grade of animals more closely related to dinosaurs than to pterosaurs, though not quite dinosaurs themselves. Why aren’t they dinosaurs? Well, to be a dinosaur you have to be in the defined boundaries of Dinosauria, which means in the group of animals containing Passer domesticus (house sparrow) and Triceratops horridus, their most recent common ancestor and all of its descendants. To get in you need morphological character states. If you really want to know all the character states that may define Dinosauria let’s go to Schultzy’s for a beer, but suffice it to say it’s all in the hips (and humeri and tibiae and ankles). Compared to the true dinosaurs, of which there are well over 1,000 extinct species and over ~10,000 living birds, the non-dinosaurian dinosauromorphs are relatively unknown. The species we have fossils for all lived in the Triassic Period (252-201,000,000 year…
