Powerful microscope captures first image of nanoscaffold that promotes cell movement

Fri, 01/11/2019 - 18:51
Using one of the most powerful microscopes in the world, scientists have identified a dense, dynamic and disorganized actin filament nanoscaffold -- resembling a haystack -- that is induced in response to a molecular signal. This is the first time researchers have directly visualized, at the molecular level, a structure that is triggered in response to a cellular signal -- a key finding that expands our understanding of how cells move.

Artificial bug eyes

Wed, 01/09/2019 - 18:09
Single lens eyes, like those in humans and many other animals, can create sharp images, but the compound eyes of insects and crustaceans have an edge when it comes to peripheral vision, light sensitivity and motion detection. That's why scientists are developing artificial compound eyes to give sight to autonomous vehicles and robots, among other applications. Now, a new report describes the preparation of bioinspired artificial compound eyes using a simple low-cost approach.
