Researchers have learned more about how mosquitoes detect skin odor, and they say their findings could lead to better repellants and traps. Mosquitoes are attracted to our skin odor and to the carbon dioxide we exhale. Previous research ...
The H7N9 bird flu virus does not yet have the ability to easily infect people, a new study indicates. The findings contradict some previous research suggesting that H7N9 poses an imminent threat of causing a global pandemic. The H7N9 ...
