Shape-Shifting Droplet Networks.
We consider a three-dimensional network of aqueous droplets joined by single lipid bilayers to form a cohesive, tissuelike material. The droplets in these networks can be programed to have distinct osmolarities so that osmotic gradients generate internal stresses via local fluid flows to cause the network to change shape. We discover, using molecular dynamics simulations, a reversible folding-u...
متن کاملShape-shifting protein channel
mechanism of oceanic control of climate. They constitute a repository for heat, fresh water and gases such as carbon dioxide, all of which are exchanged at the ocean–atmosphere interface.On the largest scale, the water masses spread and fill the ocean basins. These huge bodies of water are also the engines of large-scale ocean circulation, one that is primarily driven by so-called North Atlanti...
متن کاملEarly shape-shifting FRET probe.
I am gratified by the positive response to my recent review article (1), especially when it comes from the scientific group that made very significant contributions to the field of fluorescence resonance energy transfer probes. The papers mentioned in the letter are important and were not cited in the review because they were published after the final version of the review had already been subm...
متن کاملGrowth patterns for shape-shifting elastic bilayers.
Inspired by the differential-growth-driven morphogenesis of leaves, flowers, and other tissues, there is increasing interest in artificial analogs of these shape-shifting thin sheets made of active materials that respond to environmental stimuli such as heat, light, and humidity. But how can we determine the growth patterns to achieve a given shape from another shape? We solve this geometric in...
متن کاملX Chromosomes' Shape-Shifting Foreshadows Random Inactivation
The evolution of cooperation among nonrelatives has been explained by direct, indirect, and strong reciprocity. Animals should base the decision to help others on expected future help, which they may judge from past behavior of their partner. Although many examples of cooperative behavior exist in nature where reciprocity may be involved, experimental evidence for strategies predicted by direct...
