For centuries, the mesentery (which links the intestine to the abdomen) has been treated as a group of distinct structures in your digestive system. It wasn’t anything special. However, the medical world now has to rethink that belief. Scientists recently determined that the mesentery is really one, cohesive entity — that’s right, they confirmed the existence of a ‘new’ organ. Researchers first discovered the continuous nature of the mesentery through microscopic examinations in 2012, but the past few years have shown that it has enough function to be considered an organ. This doesn’t mean that the scientific community understands exactly what the mesentery does. With that in mind, the very act of classifying it as an organ should have a far-reaching impact. On a basic level, it’s shaking up education. The medical field had to update its definitive Gray’s Anatomy textbook to account for the new findings, and students are already learning about the mesentery as a matter of course. More importantly, it’s opening up a line of inquiry that hadn’t been available before — it’s a “whole new area of science, ” the discovery team’s J. Calvin Coffey says. If scientists can learn more about how the mesentery interacts with the digestive system, they could develop better treatments for diseases and identify conditions that are specific to this part of the body.

Researchers in fields from epidemiology to genetics are studying mummies, using the latest imaging technology. Now we know more than ever before about what lies beneath the mummies’ wrappings — and these long-dead people are telling us a lot about ancient lives and cultures. Read more… 
Beeftopia writes “Researchers discovered that inserting gut bacteria from obese people into mice without gut bacteria led to the mice becoming obese. Gut bacteria from slim people inserted into the same mice did not lead to mouse obesity. The researchers concluded (abstract) that gut bacteria from the slim people were more efficient at extracting nutrients from food than those of the obese.” Read more of this story at Slashdot. 
When it comes to hands-on learning, I can think of no classroom more compelling than a gross anatomy lab , where students of the human form dissect actual bodies from head-to-toe with their own hands. That being said, this virtual dissection table is an awfully impressive stand-in for the real thing. Read more…
