"In a stunning discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist." While the article at Sciencedaily.com may be a bit breathlessly excited about it, even the more somber source article in Nature agrees that this "may call for a reassessment of basic assumptions in neuroimmunology"
A few years ago, it occurred to a few scientists that neither mice or rats are capable of vomiting. What about other rodents? It turns out that being unable to vomit is a trait common to all rodents, not just mice and rats. Interests piqued, the researchers set out to find out why.
I waited silently for her to explain that the female pelvis is shaped slightly differently from the male’s, with a larger opening for childbearing. That part was the giveaway. The real purpose of the exercise was to make her prove her conjecture with measurements--to translate the theory to practice. I also wanted her to explain why this sexual dimorphism--that is, this sexually determined physical difference--is not nearly so pronounced in nonhuman primates, such as chimpanzees.When teacher Robert S. Root-Bernstein got this answer to his question on how you should distinguish between male and female skeletons, he had to find a way to make her realise her error without disparaging her religion.
She spoke: Males have one fewer pair of ribs than females.
The Nazi Anatomists. "How the corpses of Hitler's victims are still haunting modern science—and American abortion politics."
The Course of Their Lives. While much in medicine has changed over the last century, the defining course of a first year medical student's education is still 'Gross Anatomy.' This is their hands-on tour of a donated cadaver -- an actual human body -- and is an experience which cannot be replicated by computer models. When Milwaukee Journal Sentinel reporter Mark Johnson came up with the idea of following a med school gross anatomy class for a feature story, his editor challenged him to make it different. So he chose to intertwine the students' stories with that of Geraldine 'Nana' Fotsch, a living future donor, as sort of a stand-in for the cadaver. (Via.

Teaching Cliteracy 101: "It is a curious dilemma to observe the paradox that on the one hand the female body is the primary metaphor for sexuality, its use saturates advertising, art and the mainstream erotic imaginary. Yet, the clitoris, the true female sexual organ, is virtually invisible." ~ Artist Sophia Wallace is using street art and an art exhibition that incorporates pithy slogans, 'scientific data, historical information as well as references to architecture, porn, pop culture and human rights' to make "the case for the clit".

My name is Jake and I am a bone collector. This is his room, where he keeps his more than 100 skulls (a contender for the years most awesome cataloguing and archiving effort [look at that organization!]). How Jake cleans up animal bones [more inside]
It was Alex St. Martin's gory musket injury that paved the way for cow fistulation, a hands-on method to explore the inner workings of bovine digestion.
Get your learn on. 180+ ways of investigating the human brain = hours of fun for the whole family. Thanks to an innocuous question by a 5 year old, my entire evening is now being spent investigating and discussing the structure and workings of the human brain. This flash site lets you explore the workings of the brain according to 12 subject areas (each with subtopics which are not included in the "180" count), within each of which are 5 levels of organization from social to molecular, within each of which are three levels of explanation (beginner, intermediate, and advanced.) discovered via Wikipedia.
The pancreas is a completely crummy organ...... so which parts of the human body could you design better? Interesting article and comments.
Historical anatomy models were a marriage of art and science. From about the 13th to the 19th centuries, exquisite wax models were the state of the art. Florence's La Specola anatomical wax museum houses the works of master artists, such as Ercole Lelli, Anna Morandi, and Clemente Susini. The later years of wax models tended towards the grotesque: moulage and depictions of pathological conditions and physical anomalies. Due to the labor required and delicacy of wax models, papier-mâché became the favored production method in the 19th century, partly due to the ability to dissect the models. Over time, models became more stylized to protect the delicate sensibilities of the public. Today, models are again shocking the public with extreme realism.
