Cancer cells moving on glycoproteine strips: These strips act like splints, which allow to control and to study the movement of the cells better. Credit: Rädler Lab, Ludwig Maximilians Universität München Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise...
Top view of two collagen hydrogels that researchers decorated with immobilized mCherry proteins, which glow red under fluorescent light. The team scanned near-infrared lasers in the shapes of a monster (left) and Seattle's Space Needle (right) to create these patterns. Black regions were not scanned with the laser, and so the mCherry protein did...
Figure 1: The droplets of gallium liquid metal.

Pattern formation is a classic example of one of nature's wonders that...
Adaptation—reducing the fall out among communities and increasing their capacity to deal with climate-related disasters such as floods and drought—is a key pillar of the landmark 2015 accord The world is falling short of promises made under the Paris climate deal to help the most vulnerable nations deal with the increasingly devastating impacts of...
(a) Illustration of the structure of a nanodiamond quantum sensor coated with a pyrogenic polymer, and how it operates as a hybrid nanoheater/thermometer. (b) Electron microscope image of hybrid sensors. (c) Working principle of the hybrid sensor for measuring nanometric thermal conductivity. In a medium with high thermal conductivity, the temperature increase of the...

Microgravity is helping to find answers and models to refine the processes needed to efficiently burn solid fuel like iron dust. Are we witnessing the raise of a new 'Iron Age?' Could...
In this Feb. 28, 2019 file photo provided by the Ontario Ministry of Natural Resources and Forestry, the U.S. National Park Service and the National Parks of Lake Superior Foundation, a white wolf is released onto Isle Royale National Park in Michigan. One of the world's longest-running wildlife field studies has fallen prey to...
