Venus flytraps found to produce magnetic fields

The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the closure of the leaf lobes. ...

The pressure sensor of the Venus flytrap

All plant cells can be made to react by touch or injury. The carnivorous Venus flytrap (Dionaea muscipula) has highly sensitive organs for this purpose: sensory hairs that register even the weakest mechanical stimuli, amplify ...

Studying heart cells with nanovolcanoes

Researchers at EPFL and the University of Bern have developed a groundbreaking method for studying the electrical signals of cardiac muscle cells. The technology has numerous potential applications in basic and applied research—such ...

Carnivorous plants: No escape for mosquitoes

Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients. Most plants have developed a root system to the nutrients they need in order to survive out of the soil. ...

Quantum sensing method measures minuscule magnetic fields

A new way of measuring atomic-scale magnetic fields with great precision, not only up and down but sideways as well, has been developed by researchers at MIT. The new tool could be useful in applications as diverse as mapping ...

Sonic booms in nerves and lipid membranes

(Phys.org)—Neurons might not be able to send signals as fast as electrons in wires or photons in fiber, but what if they can communicate using miniature sonic booms? That would be quite a revolutionary discovery. A group ...

Physics at the threshold of hearing

(Phys.org) —The mammalian auditory system is one of the most sensitive detectors found in nature. Two kinds of cells, the inner and outer hair cells, work together to transduce mechanical vibrations into action potentials. ...
