What is the West Nile virus and how do mosquitos spread it?
Mosquitoes can find you using only your body heat - but they become even more effective when looking for other cues like carbon dioxide exhalation and human odor, spreads the parasite that causes malaria, which claims the lives of more than 400,000 people annually according to the World Health Organization.
The UCSB team found that animals without a functional trpA1 gene, which codes for the protein, couldn't pick up on infrared waves. Upon further examination, the researchers discovered that two of the 10 rhodopsins found in mosquitoes are expressed in the same antennal neurons as TRPA1. Their results suggest that thermal infrared directly activates TRPA1 from a closer range. Meanwhile, Op1 and Op2 can activate at lower levels and set off a chain reaction that triggers TRPA1.To protect yourself from bites, opt to wear looser clothing, which not only prevents the bugs from latching onto your skin but also causes body heat to dissipateIn addition to simply learning more about the humble mosquito, the scientists considered the real-world implications.
