(Phys.org)—A team of researchers with the University of Burgundy in France has shown that solitons can vibrate like real molecules when paired. They have published a paper describing their technique and findings in the ...
How can the color of laser light be changed? One popular method to achieve this is the so-called second harmonic generation (SHG) effect, which doubles the frequency of light and hence changes its color. However, observing ...

In an algae-eat-algae world, it's the single-celled photosynthetic organisms at the top (layer of the ocean) that absorb the most sunlight. Underneath, in the sublayers, are cryptophyte algae that must compete for photons ...

Ever since J.J. Thompson's 1897 discovery of the electron, scientists have attempted to describe the subatomic particle's motion using a variety of different means. Electrons are far too small and fast to be seen, even with ...
