Phys.org / Revealing the retina: Graphene corneal contact lens provides robust, irritation-free topographic electroretinography

Our vision can be damaged or lost by damage to the retina—a sensory membrane lining the back of the eye that senses light, converting the image formed into electrochemical neuronal signals—resulting from two classes of ...

Phys.org / Trophic coherence explains why networks have few feedback loops and high stability

(Phys.org)—Complexity – defined as having emergent properties or traits that are not a function of, and are therefore difficult or inherently impossible to predict from, the discrete components comprising the system – ...

Phys.org / Modeling morphology: Solid-solid phase transitions based on colloidal particle shape changes

(Phys.org)—Phase transitions are transformations that occur between states of matter—that is, between solid, liquid, gas, and less commonly between gas and plasma. What may be surprising is that solid-solid phase transitions, ...
