Light Pollution Suppresses Melatonin Production in Perch
Melatonin controls the body clock – high melatonin levels make us feel tired in the evening. However, the hormone also plays an important role in animals' biological rhythms. Artificial light at night – light pollution – can suppress the production of melatonin in fish, even at very low light intensities, a finding established by researchers from IGB.

Advanced "Super-Planckian" Material Exhibits LED-Like Light When Heated
Could there be a new kind of light in the universe? Since the late 19th century, scientists have understood that, when heated, all materials emit light in a predictable spectrum of wavelengths. Research published this week in Nature Scientific Reports presents a material that emits light when heated that appears to exceed the limits set by that natural law.

Transparent Material Considerations for UV Optics in Horticultural Lighting Applications
Advancements in UV LED technology have begun changing the horticultural lighting landscape. Research is still ongoing to discover the extent of benefits and best practices of using UV light in horticulture. Using optics in tandem with UV LED light systems can help reach performance goals and optimize growing. Although there are several UV- transmitting materials available, not all are equivalent or able to meet the requirements for UV applications. Justine Galbraith, glass engineer, and Sharayah Follett, market development manager at Kopp Glass, Inc. discuss the performance considerations of various UV-transmitting materials and how application challenges are addressed by integrating optical elements.
