Touch a hot plate and your hand flies back. While the response is almost instant, researchers are still working to better understand the molecular mechanisms behind these sensations of heat and pain.

Scientists have found a reason why some people never seem to get warm while others never seem to feel the cold: some nerve cell receptors deep in the body are stimulated by signals other than ...

TRPA1, also known as the "wasabi receptor," helps animals detect noxious heat and harmful chemicals. In humans, this receptor can induce eye and skin irritation. In mosquitoes, it influences which ...

Hotter temperatures may render natural insect repellents less effective against mosquitoes, according to a new study. Hotter temperatures may render natural insect repellents less effective ...

Touch a hot plate and your hand flies back. While the response is almost instant, researchers are still working to better understand the molecular mechanisms behind these sensations of heat and pain.

How heat activates protein receptor Within cell membranes, ion channel receptors typically activate in response to electrical, chemical or other specific stimuli, explains Feng Qin, Ph.D ...
