Japanese researchers demonstrated how a tiny remote-controlled drone could help bees pollinate flowers in areas where bees populations have been reduced due to pesticides, climate change, and other factors. Eijiro Myako and his colleagues at the Japan’s National Institute of Advanced Industrial Science and Technology hope that eventually robotic bees could handle their share of the work autonomously. From New Scientist:
The manually controlled drone is 4 centimetres wide and weighs 15 grams. The bottom is covered in horsehair coated in a special sticky gel. When the drone flies onto a flower, pollen grains stick lightly to the gel, then rub off on the next flower visited.
In experiments, the drone was able to cross-pollinate Japanese lilies (Lilium japonicum). Moreover, the soft, flexible animal hairs did not damage the stamens or pistils when the drone landed on the flowers...
“We hope this will help to counter the problem of bee declines,” says Miyako. “But importantly, bees and drones should be used together.”
Information security firm Bishop Fox's "Cybersecurity Style Guide" is 92 pages' worth of usage notes from the confusing world of technical jargon, a combination of glossary, pronunciation guide and style manual (in the manner of the jargon file), and includes the notation that "cyber-" is an ill-advised prefix.
GOP bigots in South Carolina and Wyoming have decided to try and weasel around the U.S. Supreme Court decision that allowed “legal” marriage to everyone. I can not begin to understand the religious babble these ‘lawmakers’ enter into, trying to describe how two people committing to share their lives is anything wrong. Jeff March, the […]
While some can only think of the Burning Man as a party in the desert, diehard Burners, its citizens, will tell you that it’s much more than it. They’ll tell you that it’s a year-round community whose leadership is, amongst other things, determined to protect their unique culture from commodification. People looking to exploit the […]
The web is vast, and while there’s room for everyone, competition is stiff when it comes to landing on that first page of a Google search. That’s why developers aren’t afraid to spend exorbitant amounts of time and money on search engine optimization (SEO) to ensure their sites rank higher than others. However, not all […]
Many of us enjoy the aesthetic of vintage electronics, but trying to use most hardware from the 1950’s isn’t necessarily practical. This is especially true where speakers are concerned. While most of us can appreciate the old-school feel of retro speakers, they have a hard time matching the convenience and power delivered by today’s Bluetooth speakers. […]
Python is one of the most popular and versatile programming languages used by developers today, making it an ideal first choice for those looking to kickstart a career in programming. While you could go back to school or sign up for a pricey coding bootcamp, you can learn the essentials of coding with Python at […]
