As global warming accelerates, the Arctic Ocean melts and the U.S. Navy estimates that by 2035 it may be ice-free for a month each year - that will mean more activity through the Northwest Passage, the Arctic shipping route which is already busier than ever. In an op-ed in Foreign Policy, James Holmes argues if and when that icy expanse opens regularly to shipping, the Arctic will need policing like any other marine thoroughfare, and he nominates the United States Coast Guard.

You step down from the all-terrain camper and out into the bright sunlight. Your boots crunch on the cold desert soil. It's been three solid months in the office with just Sundays off (at best). But now, finally, you are out in the open once again. Above you the sky is its usual brown-hued butterscotch color. Ahead of you is the trail leading to the canyon. The plan is to spend the day walking a trail at the edge of Coprates Chasma, a canyon almost a thousand kilometers long (more than twice the length of the Grand Canyon, they say).
Environmentalists and beekeepers are calling on the government to ban some of the country's most widely used insect-killing chemicals.
The pesticides, called neonicotinoids, became popular among farmers during the 1990s. They're used to coat the seeds of many agricultural crops, including the biggest crop of all: corn. Neonics, as they're called, protect those crops from insect pests.

President Obama on Monday designated five new national monuments, including one in Maryland dedicated to anti-slavery activist Harriet Tubman and another setting aside Washington state's San Juan Islands.
"These sites honor the pioneering heroes, spectacular landscapes and rich history that have shaped our extraordinary country," President Obama said in a statement. "By designating these national monuments today, we will ensure they will continue to inspire and be enjoyed by generations of Americans to come."
As far back as he can remember, George McCann lived in fear. When he was asleep he would have horrific nightmares filled with violent images. When he was awake, he often felt threatened by people, including members of his own family. And when he felt threatened, he would become aggressive, even violent.
George spent his childhood certain that something very bad was going to happen. And when he was 12, it did. His unrelenting fears led to a violent outburst at school. And George landed in a psychiatric hospital.
From Star Wars' R2-D2 to The Terminator to WALL-E, robots have pervaded popular culture and ignited our imaginations. But today, machines that can do our bidding have moved from science fiction to real life.
Think hands-free vacuum cleaners or iPhone's Siri or robotic arms performing surgery. At the Innorobo conference in Lyon, France, the latest in service robot technology was on display.

Back in 1996, a group of baby cicadas burrowed into soils in the eastern U.S. to lead a quiet life of constant darkness and a diet of roots. Now at the ripe age of 17, those little cicadas are all grown up and it's time to molt, procreate and die while annoying a few million humans with their constant chirping in the process.
