A team led by York University researchers has discovered the fastest wind near a supermassive black hole ever found at ultraviolet wavelengths, driven by the disk of matter (quasar) surrounding the black hole.
Designing surfaces that precisely control how light behaves at the nanoscale is tricky. Optical Fourier surfaces, which are nanostructured gratings that redistribute light into specific directions and wavelengths, hold enormous ...
Blurry light from lens imperfections is a problem everywhere, from microscopes to telescopes to smartphone cameras. Using a tiny yet carefully engineered optical element and artificial intelligence, University of California ...
Studying physics can be very useful—even when it comes to machine learning. A digital "super-brain" with built-in knowledge of the fundamental laws of nature can speed up the development of optical components for everything ...
Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising ...
UNSW Sydney engineers have riffed on the famous Schrödinger's cat analogy to demonstrate a more efficient way to eliminate errors in quantum computing.
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
An international team of astronomers have employed one of the Large-Sized Telescopes (LSTs) at the Cherenkov Telescope Array Observatory (CTAO) to observe a distant blazar known as OP 313. Results of the observational campaign, ...
In nature, there exist structures that are mirror images of each other but cannot be perfectly superimposed. These are known as chiral objects, derived from the Greek word for "hand," since left and right hands share the ...
Water deficit resistance in plants has long been a topic of interest for cultivating reliable crops. Some plants can alter their above-ground structure to lock in moisture, while others develop deep, industrious roots that ...
