He wanted to understand how the body was composed and how it worked. But at his death in 1519, his great treatise on the body was incomplete and his scientific papers were unpublished.
Based on what survives, clinical anatomists believe that Leonardo's anatomical work was hundreds of years ahead of its time, and in some respects it can still help us understand the body today.
So how do these drawings, sketched more than 500 years ago, compare to what digital imaging technology can tell us today?..."

That's pretty obvious, you might think, but the researchers from the Karolinska Institute and the Swedish School of Sport and Health warn that the excessively sedentary are running serious risks, irrespective of how much exercise they do when they're not plonked behind a desk, or lying on the sofa...""

Ant writes: "This Wolf Gnards asks "How Long Could Luke Survive in a Tauntaun?" and answers with:
"All good Jedi know that the best way to survive a snow storm is in the snugly belly of your nearest Tauntaun. Just cut open with your handy dandy light saber, a single horizontal slice across the midsection will do, push squirming intestines aside, and crawl right in. Warm as it is comfortable, the intestines mold to your body like a memory foam mattress. But how long could you survive in a Tauntaun?
Realistically, the sub-zero environment of Hoth is no place to be, Tauntaun or not. And it's important to remember that Luke Skywalker didn't need to survive in his Tauntaun over night, he simply needed a warm place to be until Han had time to build a proper shelter. So, the better question might be, how long did Han have to build a snow shelter until Luke was in serious trouble."
A study published online in September 2009 in The British Journal of Sports Medicine was the latest to report apparently disappointing slimming results. In the study, 58 obese people completed 12 weeks of supervised aerobic training without changing their diets. The group lost an average of a little more than seven pounds, and many lost barely half that. How can that be? Exercise, it seems, should make you thin. Activity burns calories. No one doubts that..."

The ability to digest the milk sugar lactose first evolved in dairy farming communities in central Europe, not in more northern groups as was previously thought, finds a new study led by UCL (University College London) scientists published in the journal PLoS Computational Biology.
The genetic change that enabled early Europeans to drink milk without getting sick has been mapped to dairying farmers who lived around 7,500 years ago in a region between the central Balkans and central Europe. Previously, it was thought that natural selection favoured milk drinkers only in more northern regions because of their greater need for vitamin D in their diet. People living in most parts of the world make vitamin D when sunlight hits the skin, but in northern latitudes there isn't enough sunlight to do this for most of the year...

A revolution in the science of social networks began with a stash of old papers found in a storeroom in Framingham, Massachusetts (MA). They were the personal records of 5,124 male and female subjects from the Framingham Heart Study. Started in 1948, the ongoing project has revealed many of the risk factors associated with cardiovascular disease, including smoking and hypertension.
