The luminous haze that obscures our view of the constellations - light pollution -is one of the most prevalent forms of environmental alteration. Its impact is felt across a swath of life from the migration of sea turtles to the circadian rhythm of humans.
A new atlas of light pollution created by an international team of scientists reveals just how pervasive this artificial glow is. The atlas shows that more than 80% of the world and more than 99% of the U.S. and European populations live under light-polluted skies. The Milky Way is hidden from more than one-third of humanity, including 60% of Europeans and nearly 80% of North Americans.

This is a ghostly web-footed gecko, they can be found and perfectly camouflage among the powdery reddish sands of the Namib Desert, their primary habitat.These geckos have adapted their webbed feet not only to help them stay atop, but to bury beneath the dunes of the Namib Desert. Strictly nocturnal lizards, they spend the day in self-dug burrows and emerge at night to feed.
Their bloodshot-looking eyes are massively oversized to help them detect prey, which includes crickets, grasshoppers, and small spiders. They move surprisingly quickly across the sand, and adhesive pads on their toes make them excellent climbers.
People sometimes hunt these tiny lizards for food, and human encroachment is destroying some of its habitat. Their estimated lifespan in the wild is about five years.
PBS NewsHour has a new science video series called ScienceScope - and their first episode is all about smells!
Scientists, sponsored by the National Science Foundation and the White House Brain Initiative, are trying to understand how smells travel, and how we detect them. They simulate the turbulent wafting of an order with dye in water. The hope is that this research will lead to smell-detecting robots that could replace search dogs.

“Schrödinger’s Smoke. We describe a new approach for the purely Eulerian simulation of incompressible fluids. In it, the fluid state is represented by a ℂ²-valued wave function evolving under the Schrödinger equation subject to incompressibility constraints.” YouTube.
As a child, I once touched an untouchable. For this infraction I was forced by my grandmother to swallow cow dung as a punishment. I was also made to drink cow urine and bathe in Ganga water to purify myself. This experience ingrained in me what untouchability was in the minds of my community. These women here with me once cleaned human excrement from toilets, and this made them untouchables. They had to wear bells around their necks to warn families of their approach. They were forbidden from going to the temple, doing puja, even bathing in the Ganga. Their children could only play with the pigs and not with children of higher castes.
