It sounds like the beginning of a joke: Why do dolphins carry sponges? To...um...to...well technically, it's to scoop up fish, but that's not funny...to get to the other side? No? Dang.
This paper from PLoS ONE has recently been covered by the illustrious Ed Young (he of the recent book publication!), but it's PLoS ONE's birthday, and I really think this phenomenon is cool, and so I'm going to blog it, too. So there, Ed. *ppppbbbbtttttttth* :)
So why DO dolphins carry sponges?

UGH. First off my apologies for the weird scheduling. I have no idea why it posted itself four days ago.
And I have to start this with a personal porn anecdote. You KNOW you wanna hear it.

The other day I was teaching a whole passel of high school students about cocaine and the brain. I usually give them choices about what they want to hear about, and they ALWAYS pick cocaine. I was so happy when someone picked anxiety disorders I must have looked like a total geek, but seriously, I've given that dang coke talk at LEAST 100 times. I suppose it is perfected by practice.
Anyway, I'm talkin' along, and I'm telling them that we think that dopamine is responsible for the initial re........ Read more »
Roberts DC, Corcoran ME, Fibiger HC. (1977) On the role of ascending catecholaminergic systems in intravenous self-administration of cocaine. . Pharmacology, Biochemisty, and Behavior.
This is technically history as well as science. Even though it was published in 1978, it actually refers to the cannibalistic practices of the Aztecs, whose empire was taken over by Cortes in 1521 when the Spanish conquistadores first came to the New World. If you've never heard of the Aztecs (who referred to themselves as 'Mexicas', and who are also referred to as the 'Nahua'), they are usually known to history as a warrior culture, famous for the use of human sacrifice and cannibalism.

A somewhat late Friday Weird Science, but I want to point out that Sci was not up at 4am shopping with all the crazies. I don't DO that sort of thing. Online is so much better.
So here I was, rolling myself around the house after a particularly delicious Thanksgiving dinner, and contemplating what offering to place upon the alter of the blogosphere. And then I came upon it. The scale. Normally, I'm not too obsessive about weight, but Sci is running a half marathon very, very soon (I in f........ Read more »

Thanksgiving is my favorite holiday, hands down. Well, ok, I also celebrate a series of personal holidays on the day after Valentine's, the day after Easter, the day after Halloween, and the day after Christmas. Why hinge your emotions on the uncertainty of a holiday when you have the certainty of all the chocolate going on sale the day after? Day after holidays are beautiful things and I encourage you all to celebrate with me (though I warn you, stay AWAY from the Russel Stover "european" ch........ Read more »

Think of a copper tea kettle (I'm cold, tea is warm...). When you think about it, where is it? It's in a kitchen, right? Possibly on a stove. It's definitely in a context where you would expect it to be. Now take that tea kettle, and put it in your mind somewhere like...a desert. Surrounded by sand and sky. Now you're not thinking of tea anymore. But doesn't the copper gleam a little better? It might be out of context, but the tea kettle looks really...pretty!
Ok, maybe you don't fol........ Read more »

This SHOULD be the time when I'm working crazy hard on InAdWriMo, trying to get those paper drafts up and running (ideally they should be ready on MONDAY). Perhaps I should have been doing that rather than writing a 3,000 word post on posters (Really! Count!). So it goes. But here I am, and instead of writing what I need to write, we are BACK with Friday Weird Science!

I actually had another piece in mind for this Friday's Weird Science, but a friend of mine sent me a link to this paper, and I HAD to do it. It's not just weird, it's awesome!
Long, Fee. "Using temperature to analytze temporal dynamics in the songbird motor pathway." Nature, 2008.
I will start this post with an observation. My brother and I observed, around about the time the movie "Titanic" came out, that you can do "the Macarena" to ANY song. Really. Any song you like. Pick one. Our ........ Read more »

I WAS going to blog on the history of action potentials tonight, but it's late, I'm really tired (14 hour days in the lab add up), and action potential history is hard. Luckily for all of us, a new and cool article is out in PLoS ONE! Do not fear, I'll get to that history of action potentials soon enough.

Or perhaps I should call this "Friday Weird Science...NOT!" Seriously, I'm pissed. Because when Scicurious sees a headline like this:
The Stink in Farts Controls Blood Pressure
she thinks "SWEET! This will be awesome!" and starts hunting around for the paper. The original article itself was less promising than hoped, but wishful thinking was going strong here. And imagine her surprise and dismay when the real title of the article turned out to be THIS:

First of all, I just want to say that I am in a wonderful mood today. This day would have to totally kick puppies to ruin my mood. The only dark spot is Prop 8 in California.
But there is something else to make me happy! Check this out! I absolutely wanted one of these when I was a kid. Heck, I still want one.
ANYWAY. Welcome to option number 2 for Things I could Present at Journal Club! I welcome input! This is kind of due...um, ok, tomorrow. And I have to turn in my choice today.

OMG, teh blags aspoloded! And it's all revolving around Dr. Isis. I urge everyone to check out Bora's post, it generated some great discussion and it appears that people are friendly again. And Bora said nice things about me, which I always urge people to read. :)
It's that time again! What time is it? It's time for Sci to give Journal Club. I know, it just happened. But I'm a relatively senior grad student, and our Journal Club is very small, so it happens fairly often. And so, I nee........ Read more »

*stands up bravely* Hi, my name is Scicurious, and I'm a...caffeine addict.
Well, currently I'm a recovering caffeine addict. I used to drink about 6 cups of coffee a day. The big travel mug size. I was even in a caffeine study where they needed high users, and they were shocked by my intake. It started out as just a latte every once in a while, and then...it became my life. Caffeine was my molecule, my totem. I had a tshirt and everything. But a couple of months ago I got sick of mysel........ Read more »

Until I read this paper, I seriously had no idea that spontaneous eyeblink was a clinical indicator for dopaminergic function. I guess this shows you how divorced the pure research side can be from the clinic.
But before I cover this article, I must make a plea on behalf of all over-read and over-worked grad students out there: please, if you are going to publish your data (not a review article), PLEASE present your data in a pretty pretty graph. Data tables SUCK. Nobody likes them. I see ........ Read more »

Does anyone else find "priapism" a horrifically difficult thing to pronouce? This may partially be because it's so...entertaining. Well, ok, it's entertaining for me. I imagine it leaves most guys wincing.

I'm a big proponent of exercise. I'm a runner, and when you've had a stressful day, it's amazing what a good run can do to make you feel better. I've noticed for grad students (at least at my school), when the going gets tough, the tough play sports, or go the gym. The other half (perhaps they are tougher, perhaps not), when the going gets tough, go to the bar. Some of us do both (there is a LOT of stress here, thank you).
But exercise is not just for stress relief. There are several st........ Read more »

Weird Science is going up late this week, sorry guys. But it's weird science AND historical science, which makes it double cool.
Also, NEW site from Zooillogix, and it's the CUTEST THING EVER. Called zooborns, you just want to cuddle everything on the site. It will definitely cheer you up after a bad day.
So I like this paper partially because it reminds me of a guy I knew in college. He was telling me one time of the funny exploits he had in high school. Apparently there was a period whe........ Read more »

This is one of those weeks where there is SO much to blog about and so little time to do it in! How shall I ever get to it all! This article actually came out on Tuesday, which means of course that others have now been there before me, but I like this paper a LOT and so I'm going to cover it anyway.

For Friday Weird Science, there is really nothing better than a good case report. And you guys are getting a GOOD one this week. Partially because it's really good, and partially because I have just returned from the bachelorette party of a dear friend. So you now get to meet FUN Scicurious! And see how devoted Sci is? She's so devoted she's blogging to you in a dubious mental state! It's because I care. And because, though last week I got to say "vagina", this week I get to say "penis". ........ Read more »
