At the California Lighting Teaching Center (CLTC) in Davis, California, researchers explore light from many angles. This rack of light emitting diode (LED) lightbulbs on display at the CLTC shows how different designs and bulbs can create wide varieties of light.
Light from those screens triggers a chemical reaction that makes you think it is morning
This blog is the fifth in a series of guest posts on technology and the brain to celebrate Scientific American Mind’s 10-year anniversary.
Whether you learned that light was a particle or a wave in high school physics, you likely inferred that only physicists could ultimately weigh in on the subject.
Updated optical tweezers can pluck objects as small as viruses
Editor’s note: Brain Basics from Scientific American Mind is a series of short video primers on the brain and how we feel, think and act.
Octopuses might be charismatic, but not many can literally light up a room. One enterprising designer, however, has figured out how to repurpose bacteria from rare glowing deep-sea octopuses for terrestrial illumination.
