How do photosynthetic organisms harvest light so efficiently? To help answer this question, researchers have developed an ultrafast transient absorption microscope with sensitivity approaching the ...

In the darkest depths of the ocean, where little to no light from the surface penetrates, unusual creatures thrive, many of whom create their own light via bioluminescence to hunt for prey, among ...

A group of physicists from Russia, Sweden, and the U.S. has demonstrated a highly unusual optical effect: They managed to "virtually" absorb light using a material that has no light-absorbing capacity ...

Bobbing along on the research vessel Western Flyer just outside California’s Monterey Bay, marine biologist Karen Osborn and her colleagues were hauling deep-sea fish to the surface for cataloging and ...

When photosynthetic cells absorb light from the sun, packets of energy called photons leap between a series of light-harvesting proteins until they reach the photosynthetic reaction center. There, ...

A dopant molecule accepts electrons from a chiral perovskite host, enabling visible light absorption while preserving the ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

New research refining the amount of sunlight absorbed by black carbon in smoke from wildfires will help clear up a long-time weak spot in earth system models, enabling more accurate forecasting of ...

It's not convincing to me either. Munroe is correct about etendue, of course, so that the best a lens can do is equivalent to having the object of focus be surrounded by the light source. But that ...
