Scientists have demonstrated that a 2-D man-made material called a metasurface can perform spatial differentiation and integration, the two main types of calculus problems, when illuminated by a laser beam. Essentially, the ...
(Phys.org) —All objects' colors are determined by the way that light scatters off of them. By manipulating the light scattering, scientists can control the wavelengths at which light is transmitted and reflected by objects, ...
In future, some diseases might be diagnosed earlier and treated more effectively. Researchers at the Max Planck Institute for the Science of Light in Erlangen have developed an optical method that makes individual proteins, ...

(Phys.org) —A team of researchers from several institutions in Texas has found a way to identify compounds from a distance using random Raman lasing. In their paper published in Proceedings of the National Academy of Sciences, ...
The way that algae and plants respond to light has been reinterpreted based on results from experiments studying real-time structural changes in green algae. Under particular lighting conditions during photosynthesis, the ...
