Identifying sources of light plays an important role in the development of many photonic technologies, such as lidar, remote sensing, and microscopy. Traditionally, identifying light sources as ...

In materials science an X-ray source that is hard and bright can open the door to a wealth of detail. At Diamond Light Source X-ray beams with wavelengths of 0.1–0.2 nm outshine the Sun by a factor of ...

Viruses and their hosts—whether bacteria, animals, or humans—are locked in a constant evolutionary arms race. Cells evolve defenses against viral infection, viruses evolve ways around those defenses, ...

For hundreds of a millions of years, the universe existed in the dark ages—an epoch when only primordial gasses existed. Then, a period of reionization, cleared away this foggy existence an introduced ...

In nature, many organisms glow in the dark, including lightning bugs, some squid and jellyfish, using light to attract a mate or lure prey. Now, researchers have engineered glowing succulents, plants ...

The use of alternative light sources and ultra violet lighting has changed and improved drastically over the last few years. The concept, however, remains the same as the purpose of alternative light ...
