Using butterfly morphology to 3D print colored nanostructures
ETH Zurich researchers have created artificial colors by 3D printing certain nanostructures inspired by those of a butterfly. This principle can be used in the future to produce color screens......»»
Complex green organisms emerged a billion years ago, says new research
Of all the organisms that photosynthesize, land plants have the most complex bodies. How did this morphology emerge? A team of scientists led by the University of Göttingen has taken a deep dive into the evolutionary history of morphological complex.....»»
Astronomers investigate the properties of a peculiar cataclysmic variable
Astronomers from Turkey and Russia have performed optical observations of a magnetic cataclysmic variable known as SRGA J213151.5+491400. Results of the observational campaign, presented Jan. 11 on the pre-print server arXiv, yield important insights.....»»
Researchers optimize 3D printing of optically active nanostructures
For about 20 years, it has been possible to modify surfaces via nanoparticles so that they concentrate or manipulate light in a desired way or trigger other reactions. Such optically active nanostructures can be found in solar cells and biological or.....»»
Internal morphology reveals two new species of Australian burrowing scorpions
