Chemical switch triggers critical cell activities

...on this project. In such close quarters, NEDD8 bumps the docking site, making it rotate like the paddle wheel on a riverboat that carries a notch on one of its paddles. As the docking site rotates, it carries the notch all the way around to the other side, next to NEDD8. As soon as the notch of the do...

Bats use touch receptors on wings to fly, catch prey, study finds

...ain Merkel cells, a type of "touch" cell common in bumps on the skin of most mammals, including humans. Bat touch domes are different, however, because they feature a tiny hair poking out of the center. When Zook recorded the electrical activity of the Merkel cells, he found they were sensitive to air flo...
