Do you find yourself constantly wondering whether you get more insect or mosquito바카라 웹사이트bites than others? Do you find yourself in situations where you are constantly swatting off the pesky little buzzers even though바카라 웹사이트no one else seems to be bothered by them?바카라 웹사이트
Well, you might be a "mosquito magnet". And you may have your own host of loyal mosquito followers.바카라 웹사이트
What's a mosquito magnet?
There라이브 바카라 a lot of folklore about who gets bitten more but many claims aren’t backed up with strong evidence. A new study, however, has found바카라 웹사이트that some people really are “mosquito magnets” and it probably has to do with the way they smell.
Researchers at New York's Rockefeller University have바카라 웹사이트found that people who are most attractive to mosquitoes produce a lot of certain chemicals on their skin that are related바카라 웹사이트to smell. And bad news for mosquito magnets: The bloodsuckers stay loyal to their favorites over time.
Testing smells
The findings, published Tuesday in the journal Cell,바카라 웹사이트state that바카라 웹사이트"Mosquito magnets" had high levels of certain acids on their skin. These “greasy molecules” are part of the skin라이브 바카라 natural moisturizing layer, and people produce them in different amounts, Leslie Vosshall, a neurobiologist at Rockefeller University in New York, said.바카라 웹사이트The healthy bacteria that live on the skin eat up these acids and produce part of our skin라이브 바카라 odor profile, she said.
To put mosquito magnetism to the test, the researchers designed an experiment pitting people라이브 바카라 scents against each other.
The researchers바카라 웹사이트asked 64 volunteers to wear nylon stockings around their forearms to pick up their skin smells. The stockings were put in separate traps at the end of a long tube, then dozens of mosquitos were released. The mosquitoes swarmed to the most attractive smells and in the end, the biggest mosquito magnet was around 100 times more attractive to the mosquitoes than the least attractive smell.바카라 웹사이트
Mosquitos are loyal
The researchers바카라 웹사이트used batches of바카라 웹사이트Aedes aegypti mosquitos for the experiment. These are the same mosquitoes바카라 웹사이트that spread바카라 웹사이트diseases like yellow fever, Zika and dengue. While similar results are expected from such tests with other mosquitoes, more research needs to be conducted in the area to understand specificities if any.바카라 웹사이트
By testing the same people over multiple years, the study showed that these big differences stick around, said Matt DeGennaro, a neurogeneticist at Florida International University who was not involved with the research.
“Mosquito magnets seem to remain mosquito magnets,” DeGennaro said.
While the chemicals that attract mosquitoes cannot be safely scrubbed off the skin, the new findings can lead to innovation in mosquito repulsion.바카라 웹사이트
This is not the first time that mosquito bites and their propensity to bite certain individuals has been under the lens. Reserachers have previously found different varieties of mosquitoes may have different preferences in terms of blood type. According to a paper titled바카라 웹사이트Host‐seeking behavior and fecundity of the female바카라 웹사이트Aedes aegypti바카라 웹사이트to human blood types,바카라 웹사이트the바카라 웹사이트Aedes albopictus바카라 웹사이트mosquito favors O blood type바카라 웹사이트while the바카라 웹사이트Anopheles gambiae바카라 웹사이트favors type AB.
The current study, however, proved this point: Researchers also did the experiment with mosquitoes whose genes were edited to damage their sense of smell. The bugs still flocked to the same mosquito magnets.
“Mosquitoes are resilient,” Vosshall said. “They have many backup plans to be able to find us and bite us.”
