Sleeping With the Light On May Be Harmful To You
"Exposure to even moderate ambient lighting during nighttime sleep, compared to sleeping in a dimly lit room, harms your cardiovascular function during sleep and increases your insulin resistance the following morning," announced Northwestern Medicin.....»»
Dark matter could have slight interaction with regular matter, study suggests
The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. It's why, for example, we c.....»»

Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Afar mantle plume study offers new insight into deep Earth processes
Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth......»»
Study shows virtual reality may help pedestrians and cyclists avoid harmful pollutants

Sonos workers shed light on why the app update went so horribly
Meetings with "yelling," "screaming" preceded app's release, Bloomberg reports. Enlarge (credit: Sonos) In May, Sonos updated its mobile app—to the dismay of many users. With missing features and bugs, customers compla.....»»
Extreme polar light environment of the North and South Poles sustains biodiversity, researchers suggest
Researchers working in Finland propose that the unique light environment of the Earth's polar regions creates conditions that result in circumpolar hybrid zones around the North and the South Poles. These extreme conditions increase the synchrony of.....»»
Study shows artificial light at night changes the behavior of fish, even into the next generation
Scientists have shown that light pollution—especially light in the blue spectrum—can alter the behavior of fish after only a few nights, and have knock-on effects for their offspring. The team from China has studied how female zebrafish responded.....»»

Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
Light momentum turns pure silicon from an indirect to a direct bandgap semiconductor
UC Irvine-led research reveals that the optical properties of materials can be dramatically enhanced—not by changing the materials themselves, but by giving the light new properties......»»
