NASA's Earth at Night Images Are 'Mind-Boggling'
NASA scientists created the most complete map of Earth at night to date—showing humans in all of their electric glory. But, while the photos are magical, they also show human's extreme effect on the planet.
The map, which shows a nightly Earth as it was in 2016, was made through a composite of images collected from the Suomi National Polar-orbiting Partnership (NPP) satellite.
According to NASA, creating a night map is very challenging and can only be updated every four or fives years. One large glowing obstacle is the moon, which can effect the clarity of the night lights depending on where it is positioned during each month of observation. So, the scientists had to gather moonlight-free images and color correct the ones that weren't so it all matched.
The goal of the partnership is to create a real-time night map that shows the earth as it is in any given moment. This will help scientists understand how light evolves throughout a certain period.
"We can monitor cyclical changes driven by reoccurring human activities such as holiday lighting and seasonal migrations," said Miguel Román of NASA's Goddard Space Flight Center. "We can also monitor gradual changes driven by urbanization, out-migration, economic changes and electrification. The fact that we can track all these different aspects at the heart of what defines a city is simply mind-boggling."
Electricity has really only taken hold in human life in the past century. So, this map opens a lot of doors for scientists still trying to understand how humans are creating light pollution and the effect it has on natural habitats.
Light is most disruptive to nocturnal wildlife, and can confuse an animal's migratory patterns, affect their ability to compete for and catch prey, and even cause physiological harm. Life depends on the natural fluctuation of light and dark; so disruption to these patterns impacts the ecosystem in a major way.
Now, thanks to NASA, we have a more complete understanding that will help humans and wildlife alike.
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."

Seismic airguns exploding in the ocean in search for oil and gas have devastating impacts on zooplankton, which are critical food sources for marine mammals, according to a new study in Nature. The blasting decimates one of the ocean's most vital groups of organisms over huge areas and may disrupt entire ecosystems.
And this devastating news comes on the heels of the National Marine Fisheries Service's proposal to authorize more than 90,000 miles of active seismic blasting. Based on the results of this study, the affected area would be approximately 135,000 square miles.

Is coconut oil:
- good for you
- bad for you
- neither good nor bad
- scientists don't know
The subject of this question is the source of a disagreement. Initially, the question was thought to be settled decades ago, when scientist Ancel Keys declared all saturated fats unhealthy. Coconut oil, which is solid at room temperature, is a saturated fat.
The U.S. Fish and Wildlife Service removed grizzly bears in the Greater Yellowstone region on Thursday from the Endangered Species List. The decision comes despite serious concerns in the scientific community about a declining, isolated population with diminishing food resources and record-high mortalities, as well as strong opposition from an unprecedented number of Tribal Nations.

ArborGen Corporation, a multinational conglomerate and leading supplier of seedlings for commercial forestry applications, has submitted an approval request to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service to deregulate and widely distribute a eucalyptus tree genetically engineered (GE) to be freeze tolerant. This modification will allow this GE variety to be grown in the U.S. Southeast. The reason this non-native and highly invasive tree has been artificially created to grow outside of its tropical environment is to greatly expand production capacity for the highly controversial woody biomass industry.

Many health conscious consumers are reducing their consumption of red meat in favor of chicken—especially products labeled and promoted as "100% natural"—believing they are a healthier option produced without routine antibiotics, artificial substances or other drugs.
"We have given our planet the disastrous gift of climate change ... When we we have reached similar crises there has usually been somewhere else to colonize ... But there is no new world, no utopia around the corner," he said. "We are running out of space, and the only places to go to are other worlds."
Just like John Oliver predicted, Robert E. Murray has filed a lawsuit in response to the Last Week Tonight host's June 18 show about coal that devoted a large segment skewering the Murray Energy Corporation CEO.
