Special Clothing Halts Mosquito Bites, NC researchers find

Image
North Carolina State University researchers say they have created insecticide-free, mosquito-resistant clothing using textile materials. In a press release issued last week, North Carolina said this was proven in experiments with live mosquitoes after developing materials from a computational model of their own design. Researchers modeled for the behavior of Aedes aegypti , the mosquito that carries viruses that cause human diseases like Dengue fever, yellow fever and Zeka, prompting the experiments detailed in the journal Insects . In encounters with the pesky insects, they prevented 100 percent of bites when a volunteer wore their special clothing - a base layer undergarment and a combat shirt initially designed for the military - in a cage with 200 live, disease-free mosquitoes. Researchers think their computational model could be used more widely to develop clothing to reduce transmission of disease. "The fabric is proven to work - that's the great thing we discovered,...

Plastic Free July: have some fun with it

If you haven't gotten the memo, our ocean - and yes, it is one ocean - is being choked with plastic. As the inimitable Dr. Sylvia Earle, founder of Mission Blue - which provides marine-protected areas around the globe - reminds us, our very life here on Earth depends upon this ocean. The plastic, such as in the Great Pacific Garbage Patch Gyre, contributes to altering the ocean's chemistry by absorbing C02. This causes what is called acidification, and this inhibits the ability of marine life to consume necessary nutrients, while eating away at calcium carbonate in their shells. This is Plastic Free July, a movement to draw awareness to the danger of plastic - not only for we humans but for our animal friends and most importantly the planet and our future Earth. Businesses, non-profits and individuals seem to be stepping up this year in a way I cannot remember in previous years. It's not just the storied young who care, either. Earle is in her eighties, for example. Ther...
