Comment by Cynthia McKelvey in MDMA and "Drugs Live: The Ecstasy Trials"

Thanks! It's good to be back (again haha). It's definitely hard finding the time to write if you're fully employed elsewhere! I'd love to hear from Donna, but I'm not longer at UF so maybe you coul. . .Read More

Comment by Brian Krueger, PhD in MDMA and "Drugs Live: The Ecstasy Trials"

Great to see you again!  I know I've had a hard time finding the time to continue writing with everything going on.  You know, one of the scicomm people that ran the internet outreach at UF gradu. . .Read More

Comment by Cynthia McKelvey in Salty Penguins Filter Salt Out Their Nose

Hi Dan, Sorry it took me so long to reply to your comment. I actually didn't even see it for quite some time. I did do some research though, and it turns out that the fluid within the cavit. . .Read More

This is fascinating! But where does the non-salty fluid come from (or START from)? It can't be the blood stream... . . .Read More

Thanks! Haha yeah I was wondering if that first sentence could have been worded more clearly. Although I think I look better on my camera phone than I do IRL, but maybe that's because of the poor r. . .Read More

Last summer, I became inspired to write an article about the potential benefits of the club drug, MDMA, otherwise known as Ecstasy or Molly. The blog post got turned into an article for my alma mater's science magazine, The Synapse, and was published a few months ago. With permission, I am cross-posting it here.

To many who read this blog, Notes of Ranvier is a title that probably evokes no thoughts of science or history. There is a backstory to the name, however, and a reason why I chose it as the title.

Notes of Ranvier is meant to be a play on words referring to the nodes of Ranvier, anatomical structures in certain types of neurons that have a myelin sheath. Every neuron has a long projection called an axon that transmits electrical signals to other neurons. Around the axons of some neurons is the myelin sheath, a fatty tissue that insulates the axon like plastic around a copper wire. Electricity can't travel though myelin, so there are even gaps between the sheath where the neuron is exposed and electrical currents can be propagated down the axon. These gaps were discovered by French scientist, Louis-Antoine Ranvier (pronounced rahn-vee-yeh), and thus bear his name as Ranvier's nodes or the nodes of Ranvier.

When you learn about Ranvier's nodes in class, not a lot of attention is paid to how they were discovered or why they have Ranvier's name instead of some other scientist. The treatment of the subject is far more along the lines of, "these exist, this is what they do, moving on." But the question still gnaws, who was Ranvier? How did . . . More

That simulation of reality is the only thing you've ever interacted with, it's not that the real world isn't out there--it is--but you've never been there. You've only ever interacted with this simulation of reality that's put together from sparse information from the outside world and the rest is essentially confabulated, just like that blindspot is a confabulation of sorts. . . .
