One approach to fight mosquito-borne diseases is to introduce huge numbers of sterilized male mosquitos to beat out the wild males in competition for female mosquitos. The challenge is that it's expensive to airdrop the mosquitos from airplanes and often difficult to traverse developing nations by ground. Now, WeRobotics has prototyped a drone that carries hundreds of thousands of mosquitos and releases them at just the right moment. The first experiments in South or Central America will take place in the next few months. From IEEE Spectrum:
The goal is to pack as many mosquitoes as possible into the drone. However, clumping is a problem because the insects form “a big collection of legs and wings,” he says. The trick, according to Klaptocz, is to keep them inside a precooled container: “Between 4 °C and 8 °C, they’ll fall asleep, and you can pack them up fairly densely.”
It’s also important to control the release of the mosquitoes, rather than dumping them out all at once. “We tried different systems to get the mosquitoes out of the holding canister, including vibrations and a treadmill,” he says. “Right now, we’re using a rotating element with holes through which individual mosquitoes can fall.” Once the mosquitoes fall out of the canister, they spend a few seconds in a secondary chamber warming up to the outside air temperature before exiting the drone, to make sure they’re awake and ready to fly.
Paper Mate introduced the Flair felt tip pen in the 1960s. I liked them when I was a kid because the lines were so clean and you could vary the line width. I kind of forgot about them until I was at Maker Faire and my toy inventor friend, Bob Knetzger, said he uses them […]

Amidst all the deadly serious concern and fallout from our global battle against COVID-19, you’ve likely been forced to confront more than a few moments that you never expected to face. And you likely never felt sillier during this scary time than when you were racing all over town hoping desperately that some store had […]
“It’s better to have it and not need it than to need it and not have it.” – “Lonesome Dove,” Larry McMurtry If the past few months have taught us anything, it’s that we need to be prepared now more than ever. Emergency situations can happen quickly and there’s no telling when you may need […]
Just as in almost any industry that seeks high-demand, well-trained workers, certification often becomes key. For project managers, that means anyone who’s serious about serving in that role with a respected company knows they’re going to need the seal of approval in one of the field’s most recognized methodologies before they stand much of a […]
