Mosquito courting strategies could inspire quieter drones

Science
Nov. 7 (UPI) -- The rapidly beating wings of a mosquito serve two purposes, according to a new study. The tiny blades keep mosquitoes airborne and help them locate mates. Male mosquitoes work to match their high-frequency buzz to the low-frequency hum of a female. They must carry out their courting rituals while flying through crowded airspace and tracking down their next meal. Engineers at Johns Hopkins University set out to better understand how the mosquito's wings meet the insect's aerodynamic and acoustic needs. Their analysis could be used to design quieter drones or develop chemical-free mosquito control strategies. "The same wings that are producing sound are also essential for them to fly," lead researcher Rajat Mittal, a mechanical engineering professor and expert in computatio...

New strategies for distinguishing between students who know and students who guess

Science
Dec. 28 (UPI) -- Research economists at the University of Leuven have developed new strategies for more accurately assessing the academic performance of students in online classes. According to their new paper on the subject -- published in the journal Heliyon -- there are a variety of problems with the assessments currently used for many so-called massive open online courses, or MOOCs. First, MOOC assessments generally feature too few questions. Tests featuring just 10 to 15 questions are insufficient, researchers argue. Additionally, the common use of multiple choice rewards guessing, distorting the test results. Finally, online tests used by MOOCs frequently rely on the same sets of answers, minimizing their ability to measure changes in knowledge as tests are updated. For solutions to...
