Today's post is some seriously OLD science. Old science and WEIRD science, coming to you courtesy of Mt. Sinai hospital in NYC, 1913.
And it's also the WEIRDEST conjunction of this:
That Sci has ever seen.
Gerster AG, Mandlebaum FS. "XI. On the Formation of Bone in the Human Penis." Annals of Surgery, 1913.
The pictures below are curiously safe for work. I suppose that picture up there wasn't. oops. Read the rest of this post... | Read the comments on this post...... Read more »
Let it be known that Sci, like many a young, bright-eyed little scientist, tries to keep up on her reading. TRIES is the operative word, but every week Sci gets the Tables of Contents for all the major journals in her field (and all the major ones in her subdisciple) emailed straight to her for her perusal. She scans the title lists, searching for things that are cool in her field, cool to blog, or that might indicate a scoopage of her work (hey, it happens).
And it was in one of these peru........ Read more »

OMG ZOMBIE POST!!!
Let's all pause and contemplate how awesome I look as a zombie. I DO love brains. Very much. OM NOM NOM.
So Sci was thinking about what to post for Zombie Day. She thought about wondering if dogs could sniff early stage zombie infection and thus help with quarantine. She thought about whether or not grocery stores would be a good place to hide, but Evil assured her that Costco is better (everything is better when you buy IN BULK!). She then thought about maybe finding........ Read more »

This is a paper in which Sci has a certain amount of personal investment. You see, Sci has a family member who suffers from rheumatoid arthritis. And when I say suffer, I mean she suffers terribly. Rheumatoid arthritis is an autoimmune disease where you own body attacks the lining of the membranes between your joints. The result is painful swelling and stiffness (arthritis) which usually affects the smaller joints first (like your fingers) and which can severely impair your quality of life. ........ Read more »

Thanks again to NCBI ROFL, who finds these hilarious things and posts their abstracts for all the world to see, and for Sci to giggle over and then run around trying to find hilarious pictures of didgeridoos.
So, let's talk about your snoring problem.
And then let's talk about your musical stylings on the didgeridoo.

Sci was going to save this one for a Friday Weird Science, but it's just so awesome that she couldn't bring herself to save it. She had to blog it NOW! It's not neuroscience, but it's awesome. Also, there's dragons.
Not this kind:
(Anyone else think Dragon Age Origins is really awesome?! Well, Sci spends a lot of her time wondering why the ladies are so dang naked. You're climbing a high mountain pass in the winter! Your cleavage will suffer frostbite!!!)
It's this kind:

Today's post comes to you from several tweets that Sci received way back in the mists of time (that is...two weeks ago. Three? Something like that). Sci got wind of this paper and has been meaning to blog it for a while, but other things get in the way, like other things will. And when those other things finally get out of the way, Sci sometimes finds that she's so SLEEPY she doesn't know if she can make it through any more dry, sciency prose (sciency prose, even at the best of times, is pat........

Many thanks to NCBI ROFL for providing this excellent gem of a paper. I was actually going to do another one that I found via their site, but then I saw this one and I HAD TO HAVE IT. And so much additional thanks goes to Jason of the Thoughtful Animal and twitter bud hectocotyli, who managed to find the paper, as Sci only has access to the stacks copy and was about to pull her hair out.
And it was all worth it, my friends! This is a paper of such hilarious awesome that Sci can barely conta........ Read more »

Sci was incredibly excited to see this paper come out. It's got lots of stuff going for it, and all its powers combined were enough to send Sci bouncing around in her seat and sending emails to Ed Yong saying "OMG COOL PAPER!!".
What's it got, you say? It's got the meaning of life, the universe, and that pesky MRI signal.

Today Sci is going to blog a paper that she has been meaning to blog for a long time. It's one of those papers that people who do certain kinds of science snuggle with when they go to sleep at night.
(Sci and this paper)
But the real reason that Sci loves this paper is that it's the neurobiological equivilant of a RickRoll.
And the question behind this paper is: what is the mechanism behind reward prediction?

Sci has constantly been annoyed that no one seems to have performed a real, thorough study on the sensitivity of the vagina. Or at least, it's beyond her pubmed-fu. If someone has done it, please let me know! I'd really like to cover it and I'm very annoyed that I cannot seem to find it. Sci is also annoyed by this because several studies have covered the sensitivity of the penis. It's just not fair.
But today, Sci was pubmedding furiously, and she FOUND SOMETHING. I am so excited.

This post comes to you courtesy, actually, of Sci-Dad, who sent an email to Sci saying wasn't this cool. Sci then showed it to Mr. SiT, and he was very intrigued, and insisted she cover it. Sci kind of wanted to make cake balls. Maybe that will be tomorrow.

Sci, like everyone else around here, isn't immune to the sands of time. She's getting older, along with all of her friends, who are pairing up and settling down. This means two things:
1) Sci has been a bridesmaid SIX TIMES and counting so far. The tales she could tell...
2) Sci friends are having BABIES. LOTS AND LOTS OF BABIES. 400 BABIES!
(Sci is often accused of have GRATUITOUS AMOUNTS OF ENERGY. Also, she has to wonder if these guys had ever tried the energy gel called "Chocolate ........ Read more »

This is another post in Sci's investigation into the current studies being performed on eating disorders, particularly binge eating and bulimia. Usually I try to focus on the dysregulation of reward-related systems in these disorders, but this paper will be a little different.

This is somewhat of a followup post. What's really cool about this paper (to Sci, anyway), is that it brings two different areas that she's been interested in into one cool glob of SCIENCE. And it helps to explain many of the questions that Sci got in response to two of the papers she has blogged about recently.
They are these:

Sci happened to be Pubmedding the word "vomit"* today when she ran across this article. It's one of those articles that is weird because it's. So. Obvious.
Mallett et al. "Do We Learn from Our Mistakes? An Examination of the Impact of Negative Alcohol-Related Consequences on College Students' Drinking Patterns and Perceptions" J Stud Alcohol. 2006

Sci was a little startled recently when she saw "the latest study" on ADHD splashed across the frontpage of Yahoo. You can see it here on Reuters.
PESTICIDES TIED TO ADHD.
(Run for the hills, indeed. Or maybe run AWAY from the hills, since they might have pesticides)
However, the story broke a good TWO DAYS in advance of the paper actually coming out, and so Sci was forced to possess her soul in patience until she had access.
But she's got it now! And let's take a look at this thing.

Sci wishes she could begin this post with something clever. But she has a cold. Suffice it to say that this paper is cool and interesting. And also, as Sci has a cold, I expect all of you to read this post out loud to yourselves in suitably stuffy, gluey Sci-voices.

Palmer and Schloss. "An ecological valence theory of human color preference" PNAS, 2010.
Sci will admit that she didn't really know all that much about color preference theory until she read this paper. And that until she read this paper...she thought a lot of it was silly.
Also, she doesn't have a favorite color. That might have something to do with it. Can someone have a favorite color palette instead?
Anyway, let's talk color preference theory. Read the rest of this post... | ........ Read more »

Sci watched the new Sherlock Holmes movie the other night. It's cute, and one of the things that she really enjoyed was watching Sherlock Holmes use his amazing power of deduction:
Sherlock Holmes: As to where I am, I was, admittedly, lost for a moment, between Charing Cross and Holborn, but I was saved by the bread shop on Southford Hill. The only baker to use a certain French glaze on their loaves - a Brittany sage. After that, the carriage forked left and right, and then a tell-tale bump at........ Read more »
