LED lights found to kill coronavirus

Researchers from Tel Aviv University (TAU) have proven that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be available for private and commercial use. This is the first study conducted on the disinfection efficiency of UV-LED irradiation at different wavelengths […]

Unexpected discovery leads to better understanding of migraine

Massive “plumes” of glutamate, a key neurotransmitter, surging in the brain could help explain the onset of migraine with aura—and potentially a broad swath of neurologic disease, including stroke and traumatic brain injury—according to an international study led by University of Utah Health scientists. The study, which was conducted in laboratory mice, found that an […]

A matter of balance: Asymmetric divisions are crucial to form a functional retina

Researchers at the Instituto Gulbenkian de Ciência and the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany, have discovered that in the developing retina, and important part of the central nervous system, the divisions leading to the first differentiating neurons are asymmetric and that this asymmetry is necessary to generate the […]
