An updated version of the famous study seeing how long it takes for pitch to drop lets students speedily investigate the divide between solid and liquid
Oh hai tumblr. I saw this and thought of you. Remember my post in… erm… 2012… gee that was a long time ago. Remember the world’s longest running experiment: the pitch drop? This is a variation on that one using much lower viscosity pitch - 30 times less - which can be run over months rather than decades. It’s pretty cool to see a faster version.
Where have I been? I’ve spent the last 9 months trying to figure out how to be a PhD student. It’s mad and awesome and really hard work, but I like it. Maybe I’ll share some things with you. Radiation biology is pretty cool.
Dominant vs. Recessive Alleles: Bite Sci-zed (by Alex Dainis)
A brilliant way to teach science through storytelling.
Scientists love a good mystery. Nicely done Alex.
Which Came First - The Chicken or the Egg?
You know you’ve always wondered. Impress your friends with this scientific proof and maybe settle the debate once and for all! Or maybe not . . ?
Of course it was the Egg! Duh guys…
Biofilm: A New (Gross) Thing to Worry About
Slime can be great, but when it’s the wrong kind of slime (you know, the kind that can kill you?), it gets added to the list of things Hank wishes he didn’t have to worry about. Scientists call it biofilm, and it’s a type of bacterial colony that produces a sticky organic glue which anchors the organisms to each other and to whatever surface they fancy.

Biofilms! This is one of the topics I’m studying for my Infection and Immunity exam next week. (Last one of the semester, hooray!)
These are a huge problem in patient with Cystic Fibrosis and can make opportinistic bacterial infections like Pseudomonas aeruginosa, which loves to infect medical devices like respirators and catheters, really difficult to treat.
And yes, be glad they didn’t include any pictures…
