Scientists have created twisted laser beams that interact differently with right-handed and left-handed molecules, revealing their identity through the fragments they produce. The approach could ...
Light typically interacts with a material the same way whether it enters through the front or the back—like polarized ...
Astronomers have caught a supermassive black hole straying far from the centre of its galaxy using light from a star being ...
Optical cavities – two mirrors arranged to reflect light multiple times between them – form the basis of lasers and certain ...
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, ...
In this useful Tools & Resources article, the authors describe a new cryogenic light microscopy design and characterize its temperature and spatial stability. This compelling system avoids the ...
A new Hubble image of galaxy cluster MACS J1141.6-1905 looks almost impossibly crowded — dozens of galaxies in different shapes and sizes packed toward the center of the frame, interrupted here and ...
Physicists at CU Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The researchers say the device could ...
In Qing dynasty China, artisans augmented decorative pieces by incorporating iridescent kingfisher feathers—a technique known as tian-tsui. Scientists at Northwestern University’s Center for ...
High harmonic generation (HHG) sources in the extreme-ultraviolet (EUV) have been successfully used in a variety of nondestructive, nanometer-scale, quantitative imaging and metrology applications.
Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal ...
