Young plants need lots of light to grow, but when started indoors, natural isn't always best. Learn seedling light requirements – and when to give them a boost.

Dynamic light scattering (DLS) measures intensity fluctuations in the scattered light resulting from Brownian motion of the illuminated molecules or particles.

Some neurological disorders can be improved through photobiomodulation, a non-invasive technique based on the application of low-intensity light to stimulate altered functions in specific regions ...
