Evidence Of Link Between Childhood Cancer And Phototherapy For Jaundice Examined

Two new studies can't prove a link between childhood cancer and light therapy for newborn jaundice but the authors say it still raises enough questions that clinicians should exercise caution in prescribing the treatment for infants whose jaundice is ...

QED: First Direct Evidence Of High Energy Light-by-light Scattering, Where Photons Interact And Change Direction

Physicists from the ATLAS experiment at CERN have confirmed one of the oldest predictions of quantum electrodynamics (QED), finding the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of ...

No Isolator Needed: Space-Time Metasurface Makes Light Reflect Only In One Direction

Light propagation usually goes both ways; it is reciprocal in that the trajectory of light traveling one direction is identical in the opposite direction. Isolators and circulators, which make light propagate only in one direction, are vital building block ...

Forbidden Light In The Quantum World

Using light waves to accelerate supercurrents can discern forbidden light the quantum world, where the conventional laws of physics are already forbidden. Supercurrents are scientifically strange. At super cold temperatures, they can give us electricity th ...

Dome A On The Antarctic Plateau Is The Ideal Spot For The Next Big Telescope

There will never be another large telescope built in the United States, due to the influence of environmental activists, so those high-paying multicultural white collar jobs are instead going to Chile. But if we want even better conditions. Dome Angus, the ...
