Phys.org / Venus flytrap's snap may come from rapid cell wall softening, not water flow

The Venus flytrap (Dionaea muscipula) is a marvel of nature, a highly effective killer that doesn't have to move an inch to capture and kill its prey. It releases a fruity nectar scent to attract flies and other insects. ...

Phys.org / Slime molds make decisions using internal fluid flows

Despite lacking brains or nervous systems, slime molds are capable of making surprisingly sophisticated decisions: navigating mazes, finding food and even remembering where they found it last time. How they manage to do all ...

Phys.org / Brains update sensory predictions through single timing hub, electric fish study finds

In the split second after you hear a noise, your brain is already making a potentially life-or-death deduction: Did I do that, or did something else? Our nervous systems answer this question using something called corollary ...

Phys.org / Why birds ignore Newton: New theory could sharpen models of flocks, crowds and cells

Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are ...
