Daily exposure to blue light may accelerate aging, even if it doesn’t reach your eyes
Fruit flies exposed to blue light had significantly reduced longevity than those exposed to natural light or kept in darkness. Exposure to blue light for 12 hours a day accelerated aging phenotypes, causing retinal damage, neurodegeneration, and impaired locomotion.... Read More...

Multitasking with perfection: Nerve cell works like 1400 individual cells – Fly Study
CT1 cells connect around 1400 areas in the fly brain. Each cell area works like a separate neuron, allowing CT1 to access information from the fly's eye and support local motion detection.... Read More...
Microglia, immune cells of the central nervous system, shown to regulate neuroinflammation
In uveitis, microglia facilitates the entry of inflammatory immune cells into the retina, enabling the host immune responses to attack cells not normally recognized by the immune system.... Read More...
