Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.
Hitting molecules with two photons of light at once set off unexpected processes that were captured in detail with SLAC’s X-ray laser. Scientists say this new approach should work for bigger and more complicated molecules, too, allowing new insights into molecular behavior.
The 1950s and ‘60s poisoning event was long attributed to methylmercury, but studies at SLAC suggest a different compound was to blame. The findings could reshape toxicologists’ understanding of disease related to mercury poisoning.
A better understanding of this phenomenon, which is crucial to many processes that occur in biological systems and materials, could enable researchers to develop light-sensitive proteins for areas such as biological imaging and optogenetics.
