Humans have been massacring each other for at least 10,000 years, new evidence suggests. Fossilised remains of men, women, and children showing clear signs of being violently massacred have been discovered in Kenya, suggesting that humans have been engaging in warfare for at least 10,000 years.

Census Bureau estimates that “more than half of the nation’s children are expected to be part of a minority race or ethnic group;” LG plans to have tripled its solar panel production by then; there’ll be another Olympic Games; and, oh yeah, robots will apparently take over some five million jobs. The Changing Face of Saudi Women. POWER BRUNCH, SAUDI VERSION Aljazi Alrakan (standing), a dentist and self-described lifestyle blogger, joins friends in a fashionable Riyadh restaurant.

The Changing Face of Saudi Women

Medicine and teaching were careers open to Saudi women early on; both suited a single-sex clientele. With more women than men now in universities, “there are new careers,” Alrakan says. “I look at girls in their early 20s, and I think, They carry themselves more confidently.” By Cynthia Gorney Photographs by Lynsey Addario Published January 13, 2016. Interpretare Colonia, fuori dai bar. For the second time in human history, we are witnessing a new geological epoch. 11,700 years ago, the Earth suffered a catastrophic climate change.

For the second time in human history, we are witnessing a new geological epoch

As the ice age ended, sea levels rose by 120 meters, the days grew warmer, and many kinds of plant and animal life died out. But one animal began to thrive more than ever before. Homo sapiens, which had already spread to every continent except Antarctica, came up with a new survival strategy. Today, we call it farming. Thanks in part to that innovation, humans survived to witness the dramatic transition from the Pleistocene epoch to the Holocene—it was the first such geological transition in almost 2 million years. Remember the Holocene. Why Americans Work So Much Despite Economist John Maynard Keynes's Prediction. How will we all keep busy when we only have to work 15 hours a week?

Why Americans Work So Much Despite Economist John Maynard Keynes's Prediction

That was the question that worried the economist John Maynard Keynes when he wrote his short essay “Economic Possibilities for Our Grandchildren” in 1930. Most Americans Aren’t Middle Class Anymore. Kathryn Donohew Photography / Getty Images Presidential hopefuls from both parties have been saying throughout the primary campaign that the American middle class is in trouble.

Most Americans Aren’t Middle Class Anymore

Bernie Sanders says it is in the midst of “a 40-year decline.” Jeb Bush says it is “shrinking.” Ted Cruz says it is “headed in the wrong direction.” And Hillary Clinton says the “basic bargain” that hard work could move families into the middle class “has eroded.” A new report from the Pew Research Center says the candidates may be right. The Pew report looks at middle-income households, which it defines as those earning between two-thirds and double the median household income. In 2015, just under 50 percent of American adults lived in middle-income households. What Ever Happened to Metrosexuals? This article originally appeared on VICE UK.

What Ever Happened to Metrosexuals?

When I was 13, I got really into hair products: Wella Shock Waves Gel, Wet Look VO5, Fudge Styling Wax, L'Oreal Extra Strength, Aussie Mousse, basically anything that promised to texture, control, or volumize my greasy crown. At one point I was applying several of these gloopy potions daily, ruffing my follicles into a crispy, lacquered mess. Beneath the fiberglass meringue that was my barnet you would usually find a combination of Paul Smith aftershave, Nivea moisturizer, Levi's engineered jeans (straight from Cromwell's Madhouse), and reproduction 70s football training tops with "BRA" on one side and "ZIL" on the other. It would have been a ridiculous look for anyone, but especially for a 13-year-old. My pustular skin didn't need to be made any more moist and I didn't even own a razor, let alone need expensive aftershave.

Half the World Lives on 1% of Its Land, Mapped. The people of Earth really love their cities.

Half the World Lives on 1% of Its Land, Mapped

In the simple map above lies a stark spatial imbalance: half the people in the world cram into just 1 percent of the Earth’s surface (in yellow), and the other half sprawl across the remaining 99 percent (in black). Data viz extraordinaire Max Galka created this map using NASA’s gridded population data, which counts the global population within each nine-square-mile patch of Earth, instead of within each each district, state, or country border.

Out of the 28 million total cells, the ones with a population over 8,000 are colored in yellow. That means each yellow cell has a population density of about 900 people per square mile—“roughly the same population density as the state of Massachusetts,” Galka writes in the accompanying blog post. The black regions, meanwhile, reflect sparser population clusters. Take this close-up of South and East Asia. Asia’s densest spots are mostly concentrated in the inland urban areas.
