Hugh Jackman as 'Wolverine'One of the big advantages enjoyed by Wolverine in the X-Men movies is his ability to regenerate flesh after he's been injured in battle. Thanks to his adamantium-reinforced skeleton and his regenerating flesh, Wolverine is virtually indestructible. The idea has been widely used in sci-fi literature and movies, and it's something I think about every time I cut off the tail of a newt and watch it grow back. (Just kidding on that one. I love all animals, whether real or imaginary.) Of course, regrowing arms and legs and other body parts, that's strictly science fiction, right?

In real life, scientists have been working toward tissue regeneration for years, and a recent report says that scientists "may be one step closer to regenerating tissue like salamanders or newts do." Via the Ivanhoe Newswire, we learn that scientists at the Stanford University School of Medicine have been investigating "run-of-the-mill muscle cells" to see whether they can be induced to re-enter the cell cycle and "begin proliferating." They've had some limited success with the muscle tissue in mice, and want to see if the new techniques work with other cell types.

Here's hoping the scientists find success with their research and will use it to the greater good of mankind. As opposed to, say, doing what Tommy Lee Jones does to that weapons dealer in Men in Black: blow his head off because it will grow right back.
