Scaling down ionic transistors to the ultimate limit

The human brain is a vast network of billions of biological cells called neurons which fires electrical signals that process information, resulting in our senses and thoughts. The ion channels of atomic scale in each neuron ...

Uncovering the structure and gating mechanism of a7 protein

UT Southwestern researchers have identified the structure of a key member of a family of proteins called nicotinic acetylcholine receptors in three different shapes. The work, published online today in Cell, could eventually ...

Scientists pioneer new method of measuring electricity in cells

Electricity is a key ingredient in living bodies. We know that voltage differences are important in biological systems; they drive the beating of the heart and allow neurons to communicate with one another. But for decades, ...

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 ...

Nanomaterial acts as a molecular thermometer

A layered material developed by KAUST researchers can act as a precise temperature sensor by exploiting the same principle used in biological ion channels.
