UCSF's Julius Explains to NPR How the Body Detects Cold and Feels Pain
NPR's All Things Considered reports that "[m]int feels cool and soothing. The heat of chili peppers or wasabi can make you cry. Now, scientists at the University of California, San Francisco have figured out the connection between taste and temperature."
David Julius, PhD, chair of the department of physiology at UCSF, talks to NPR's Debbie Elliott about his findings, reported online in the journal Nature. Julius and researchers from Yale and the University of Wisconsin discovered that protein receptors at the end of nerve cells reacted to foods that mimic heat and cold the same way they responded to actual temperature changes.
