Today in Research: The Case for Circumcision; World's Tallest Man

Discovered: The temperature at which Greenland's ice sheet will disappear, a case for circumcision, a very precise 3-D printing technique, and the world's tallest man will not grow any taller.

• A case for circumcision. Considering this ritual involves cutting off part of a penis, it needs a case -- some don't quite believe the whole thing is necessary. Well, science has one for the pro-circumcision crowd: Snipping the tip has been linked to lower prostate cancer risk. Circumcision has also been associated with lower HIV and HPV risk. So, sounds like the way to go, no? "I would not go out and advocate for widespread circumcision to prevent prostate cancer," said researcher Jonathan L. Wright. But, some might argue, better be safe (and foreskinless) than sorry. [Reuters]

• The world's tallest man will not grow any taller. Having already made it into the Guinness Book of World Records, the 8-foot-3 inch Sultan Kosen of Turkey doesn't have to grow anymore. This isn't all about competition, though. Kosen has acromegaly, an illness that causes excessive growth and can lead to death, if not treated properly. "His skeleton just can't support him," explains Dr. Mary Lee Vance. But, with a new hormone treatment, doctors were able to stop the growth. "The treatments that we provided at the University of Virginia have stopped the production of his excess growth hormone and stopped the growth of the tumor itself," adds Dr. Jason Sheehan. [UVA]
