In a new comparative study of insect repellents containing the chemical commonly known as DEET and plant-based repellents, products with DEET showed by far the greatest effectiveness in preventing mosquito bites, medical researchers say.
The study, appearing in the July 4 New England Journal of Medicine, found all products tested that did not contain DEET to be significantly less effective. Authors are Drs. Mark S. Fradin, a Chapel Hill, N.C., dermatologist and adjunct faculty member at the University of North Carolina at Chapel Hill; and John F. Day, professor of medical entomology at the University of Florida.
"We took 16 representative DEET and non-DEET products that were readily available to consumers as insect repellents and tested them carefully, repeatedly and in a way that eliminated as many variables as we could," said Fradin, clinical associate professor of dermatology at the UNC School of Medicine. "We controlled how many mosquitoes we had, their ages, how well-fed they were, what the temperature and humidity were, the levels of light and darkness and so on."

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
