Light Pollution Suppresses Melatonin Production in Perch

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. Read more »

Advanced "Super-Planckian" Material Exhibits LED-Like Light When Heated

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. Read more »

LRC Evaluates Hybrid UV/Blue Light Lighting System to Reduce Healthcare-Associated Infections

LRC Evaluates Hybrid UV/Blue Light Lighting System to Reduce Healthcare-Associated Infections People who visit hospitals are expecting care and treatment, not additional complications, yet approximately 1 in 25 patients contract healthcare-associated infections (HAIs) in U.S. hospitals, according to the Centers for Disease Control and Prevention (CDC). Standard cleaning procedures usually involve manual application of detergents and disinfectants. Unfortunately, the efficacy of these manual cleaning procedures can vary considerably. In fact, less than 50% of patient room surfaces are properly cleaned. Read more »

Flickering Light Mobilizes Brain Chemistry that May Fight Alzheimer's

Flickering Light Mobilizes Brain Chemistry that May Fight Alzheimer's For over a century, Alzheimer's disease has confounded all attempts to treat it. But in recent years, perplexing experiments using flickering light have shown promise. The promise of flickering light to treat Alzheimer's takes another step forward in this new study, which reveals stark biochemical mechanisms: 40 Hertz stimulus triggers a marked release of signaling chemicals.

Research Confirms that Light Pollution Can Suppress Melatonin Production in Humans and Animals

Research Confirms that Light Pollution Can Suppress Melatonin Production in Humans and Animals Melatonin sets the internal clock. Researchers from IGB in an international team have analyzed data on the impact of light pollution on melatonin formation in humans and vertebrates. They found that even the low light intensities of urban skyglow can suppress melatonin production. Melatonin influences the metabolism and other body functions. Read more »

University of Manchester Scientists Suggest Blue Light Not So Disruptive to Sleep as Thought

University of Manchester Scientists Suggest Blue Light Not So Disruptive to Sleep as Thought Contrary to common belief, blue light may not be as disruptive to our sleep patterns as originally thought. According to the team, using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial to our health. Twilight is both dimmer and bluer than daylight, they say, and the body clock uses both of those features to determine the appropriate times to be asleep and awake. Read more »

Tailored Light Improves Sleep Quality, Depression, Agitation in Older Adults with Alzheimer's Disease

Tailored Light Improves Sleep Quality, Depression, Agitation in Older Adults with Alzheimer's Disease Most people associate Alzheimer's disease with profound memory loss, but it is often the symptoms - sleep disturbances, depression, and agitation - that are a challenge to treat, and can significantly reduce the quality of life for both the affected individual and their family members and caregivers. In a research project funded by the National Institute on Aging (NIA), Dr. Mariana Figueiro, Professor and Director at the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, is investigating whether a tailored lighting intervention can lessen the impact of these symptoms in older adults living with Alzheimer's disease and related dementias (ADRD).
