The U.S. Navy debuted its “Great Green Fleet”a group of ships fueled by a mixture of petroleum and beef faton Wednesday, signaling a foray into a future less dependent on fossil fuels.

The fleet, which is scheduled to depart from San Diego next week, consists of a nuclear-powered aircraft carrier and three escort shipsthe first to operate regularly on a biofuel-containing concoction, reports the Associated Press. For now, the mixture is only 10 percent beef fat and 90 percent petroleum because of the high cost of incorporating the fat. Eventually, the Navy aims to use a 50-50 ratio and plans to explore other sources of biofuel, including landfill, wood chips, and even food waste, says Navy Secretary Ray Mabus.

The Navy recognizes its need to reduce its carbon footprint—the service is responsible for a third of the energy used by the Department of Defense, which is the largest energy consumer in the world. But its motives are also economic and political.

“It gives us a strategic advantage,” Mabus told AP, referring to the United States’ reliance on oil exports from foreign countries that are not necessarily sympathetic to the American government or military. Alternative energy also provides an escape from the fluctuating prices of oil.

How eco-friendly the Green Fleet actually is remains up for debate. Even though it’s a good thing to rely less on fossil fuels, the meat industry itself contributes roughly 18 percent of greenhouse gas emissions, and environmentalists worry that biofuel production would require a harmful amount of land, fertilizer, and fuel.

But Mabus asserted that no land designated for food production would be used to cultivate biofuel. And this achievement is not the end; the Navy plans to continue developing more sustainable technology and reducing its consumption of natural resources in the future.


We've all felt lonely at some point in our lives. It's a human experience as universal as happiness, sadness or even hunger. But there's been a growing trend of studies and other evidence suggesting that Americans, and people in general, are feeling more lonely than ever.

It's easy to blame technology and the way our increasingly online lives have further isolated us from "real" human interactions. The Internet once held seemingly limitless promise for bringing us together but seems to be doing just the opposite.

Except that's apparently not true at all. A major study from Cigna on loneliness found that feelings of isolation and loneliness are on the rise amongst Americans but the numbers are nearly identical amongst those who use social media and those who don't. Perhaps more importantly, the study found five common traits amongst those who don't feel lonely.

In September 1939, the Nazis invaded Poland. By April 1940, the gates closed on the Lodz Ghetto, the second largest in the country after Warsaw.

Throughout the war, over 210,000 people would be imprisoned in Lodz.

Among those held captive was Henryk Ross. He was a Jewish sports photographer before the Nazi invasion and worked for the the ghetto's Department of Statistics during the war. As part of his official job, he took identification photos of the prisoners and propaganda shots of Lodz' textile and leather factories.

Joey Grundl, a pizza delivery driver for a Domino's Pizza in Waldo, Wisconsin, is being hailed as a hero for noticing a kidnapped woman's subtle cry for help.

The delivery man was sent to a woman's house to deliver a pie when her ex-boyfriend, Dean Hoffman, opened the door. Grundl looked over his shoulder and saw a middle-aged woman with a black eye standing behind Hoffman. She appeared to be mouthing the words: "Call the police."

"I gave him his pizza and then I noticed behind him was his girlfriend," Grundl told WITI Milwaukee. "She pointed to a black eye that was quite visible. She mouthed the words, 'Call the police.'"

A post on the Murdered by Words subreddit is going viral for the perfect way a poster shut down a knee-jerk "double-standard!" claim.

It began when a Redditor posted a 2015 Buzzfeed article story about a single dad who took cosmetology lessons to learn how to do his daughter's hair.

Most people would see the story as something positive. A dad goes out of his way to learn a skill that makes his daughter look fabulous.
