For most, the time spent staring at screens — on computers, phones, iPads — constitutes many hours and can often disrupt sleep. Now, Salk Institute researchers have pinpointed how certain cells in the eye process ambient light and reset our internal clocks, the daily cycles of physiological processes known as the circadian rhythm. When these cells are exposed to artificial light late into the night, our internal clocks can get confused, resulting in a host of health issues. Continue reading “Why screen time can disrupt sleep”

Even though you are not aware of it, your eyes play a role in searing an image into your brain, long after you have stopped looking at it. Continue reading “Can’t get an image out of your head? Your eyes are helping to keep it there.”
A team of bioengineers at UC San Diego has answered a question that has long puzzled neuroscientists, and may hold a key to better understanding the complexities of neurological disorders: Why are axons, the spindly arms extending from neurons that transmit information from neuron to neuron in the brain, designed the way they are? Continue reading “Why are neuron axons long and spindly? Study shows they’re optimizing signaling efficiency”
