Bird or hare: An optical illusion of an animal confuses the Internet

No, it's definitely a bird. But hey, you are the judge. A video of a black beast scraping nicely spreads quickly on the Internet as people take sides in another big debate. Daniel Quintana, a scientist at Oslo University in Norway, is responsible for all of this – he found the video on a sharing site on Sunday and tweeted …

Self-organizing materials can form patterns that may be useful for optical devices

Scanning electron micrographs of the crystal structure of the block copolymer material illustrating its unusual quasicrystal symmetries. Regions with different symmetry properties are highlighted in different colors, and examples of the different patterns that resemble some old tile patterns are shown in the attached diagrams. Picture credits: Massachusetts Institute of Technology Self-assembling materials, known as block copolymers, which are known …

Alien life BREAKTHROUGH: Alien hunters make PETABYTE of radio and optical data public | Science | News

Looking for alien life shows no signs of letting up as it continues to be pursued today by national space agencies, academics and charities. However, no one has convincingly proven the existence of any biological beyond the bounds of our planet. Breakthrough Listen is a £ 80million ($ 100million) alien-hunting project launched by dignitaries including scientific colossus Professor Stephen Hawking. …

Poor Astronomy | A young, hot exoplanet that was first observed with optical interferometry

Exoplanet discoveries seem to occur virtually every day; We become really good at discovering alien worlds orbiting strange stars. At present, about 4,000 such discovered planets are counted, which is unbelievable since the first one was not found until 1992! There are many different ways to discover them, but one of the most impressive is direct imaging: a picture of …

Optical 3D biopsies within reach thanks to advances in light field technology

Modal structure in fiber optic bundles captures light field information. Picture credits: Marco Capelli, RMIT University Researchers have shown that existing fiber-optic technology can create 3-D microscopic images of tissue in the body that pave the way for 3-D optical biopsy. Unlike normal biopsies, where tissue is harvested and sent to a lab for analysis, optical biopsies allow the clinician …
