But commercial bees sometimes stray from farm fields to peruse nearby wildflowers. Now, scientists have found that—like for many humans—a jolt of caffeine helps bees stay on task and get the job done more efficiently. Arnold and her colleagues showed that feeding bumblebees caffeine while exposing them to a target floral scent encourages them to seek out that smell when they leave the nest. The caffeinated bees visit the target-scented flowers more quickly and often than those without that extra boost. The findings could be applied to industrial agriculture to train bees to stay more on track, the team reported Wednesday in Current Biology.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
