2 U.S. researchers share Nobel medicine prize

Two scientists won the Nobel Prize in Medicine on Monday for their discoveries into how the human body perceives temperature and touch, revelations that could lead to new ways of treating pain or even heart disease.
Americans David Julius and Ardem Patapoutian identified receptors in the skin that respond to heat and pressure. Their work is focused on the field of somatosensation, which explores the ability of specialized organs such as eyes, ears and skin to see, hear and feel.
"This really unlocks one of the secrets of nature," said Thomas Perlmann, secretary general of the Nobel Committee, in announcing the winners. "It's actually something that is crucial for our survival, so it's a very important and profound discovery."
The committee said Julius, who was born in New York and now works at the University of California at San Francisco, used capsaicin, the active component in chili peppers, to identify the nerve sensors that allow the skin to respond to heat.
Patapoutian, who was born in Lebanon and now works at Scripps Research Institute at La Jolla, Calif., found separate pressure-sensitive sensors in cells that respond to mechanical stimulation.
Perlmann said he managed to get hold of both of the winners — who shared the prestigious Kavli Award for Neuroscience last year — before Monday's announcement.
"I (...) only had a few minutes to talk to them, but they were incredibly happy," he said. "And as far as I could tell they were very surprised and a little bit shocked, maybe."
As Vladimir Putin and his large entourage touch down Thursday in Beijing for a two-day state visit, there were be plenty of public overtures about cooperation, but with China facing increasing pressure from the U.S. over its trade relationship with Russia, China's President Xi Jinping will have to figure out how far the country is willing to go to prop up what was once described as a "no-limits" partnership.
