Why Are Some People Mosquito Magnets And Others Unbothered? Metabolism, Body Odor, Mindset?

It’s rare to attend an outdoor party in warm weather without hearing people complain about mosquitoes. They swat away, sit in campfire smoke, cover up with blankets and eventually just give up and go indoors. On the other end of the spectrum, there are plenty of people who don’t seem bothered by mosquitoes in the slightest. As a medical entomologist who’s worked with mosquitoes for more than 40 years, I’m often asked why some people seem to be mosquito magnets while others are oblivious to these blood-feeding pests buzzing all around them. Most mosquito species, along with a host of other arthropods – including ticks, fleas, bedbugs, blackflies, horseflies and biting midges – require the protein in blood to develop a batch of eggs. Only the female mosquito feeds on blood. Males feed on...

The Immune System Metabolism, And Genes Controlling Aging Can Be Influenced By Exposure To Man-Made Chemicals

Today humans are exposed to thousands of man-made chemicals. Yet the effects on people’s health are still not fully understood. In 2020 the number of registered chemicals reached 167 million. Every day people are exposed to them through food, water, contaminated air, drugs, cosmetics and other man-made substances. Less than 1% of these chemicals were tested for toxicity, and those that were tested demonstrate ability to disrupt almost every biological process in our body. Can we infer how cumulative exposures shape our health? I am an environmental toxicologist studying effects of man-made chemicals on our health. I decided to develop a computational approach to objectively compare sensitivity of all genes to all chemicals and identify the most vulnerable biological processes. Unbiased a...
