The parasite that causes malaria-a malady that killed 435,000 people, mainly in Africa, in 2017-is carried by older females of Anopheles mosquitoes, the Economist reports. But while gender can quickly be determined by looking at the mosquitoes' mouths, figuring out species and age is a time-consuming process that requires sequencing DNA, dissecting the bugs under microscopes, and conducting chemical analyses. Researchers at the University of Glasgow and Tanzania's Ifakara Health Institute are trying to develop a faster technique using infrared spectroscopy. The process involves crushing a mosquito between steel and a diamond and then hitting it with a laser, the magazine explains. The light absorbs chemicals in the mosquito, and when it is reflected back and read by a spectroscope, certain frequencies, or Fraunhofer lines, are missing. …
