Researchers in India discovered that cicadas begin their dawn chorus when the sun is exactly 3.8° below the horizon, demonstrating an astonishing level of precision in tuning their singing to specific light levels during civil twilight, revealing complex collective decision-making influenced by environmental cues.
New research suggests that increased light sensitivity in Alzheimer's patients may contribute to "sundowning" and sleep disruptions, potentially accelerating the progression of the disease. Light therapy could be a valuable tool to manage erratic sleep patterns caused by altered circadian rhythms. Understanding the effects of Alzheimer's on the biological clock may also offer strategies for disease prevention, as poor sleep quality in adulthood is a risk factor for Alzheimer's. The study highlights the role of the retina in enhanced light sensitivity in Alzheimer's, providing a promising avenue for the development of new treatments and prevention methods.
