Scientists find a way to extract color from black

by University of Birmingham, Phys.org

Scientists have developed a way of extracting a richer palette of colors from the available spectrum by harnessing disordered patterns inspired by nature that would typically be seen as black.

Colors that we see in nature often come from nanoscale patterns that reflect light back in particular ways. A butterfly’s wing, for example, might appear blue because tiny grooves in the surface of the wing cause only blue light to be reflected.

MIT can shrink 3D objects down to nanoscale versions

by Jon Fingas, engadget

It could be useful for tiny parts in robotics, medicine and beyond.

It’s difficult to create nanoscale 3D objects. The techniques either tend to be slow (such as stacking layers of 2D etchings) or are limited to specific materials and shapes. MIT researchers might have a better way — they’ve devised a technique for making nanoscale versions of 3D objects using a wide variety of materials and shapes. The team ultimately reversed a process for imaging brain tissue, whittling a relatively large object down to a creation one thousandth its original size.
