When wolves were reintroduced to Yellowstone National Park in the United States in the mid-1990s, after being absent nearly 70 years, the most remarkable "trophic cascade" occurred, effecting hundreds of other species.

Gary Wockner, a wolf expert in Colorado explained, "Willows grew higher and spread more widely, beavers returned and made ponds, riparian-dwelling plants and animals returned including songbirds and trout, elk carrion fed scavengers such as grizzlies and ravens, and coyote populations dropped resulting in more ground squirrels and gophers which in turn fed hawks and eagles."

The species remix that was created by wolves has also changed the rivers in the park.

The story of the Himalayan dog titled "winter is coming" that went viral came from amateur photographer and 500px member, Sebastian Wahlhütter. We spoke with him about photography, that loveable dog, and the photo that bounded him into fame.

Hey Sebastian! Can you tell us a bit about how you got into photography?

I had my first serious encounter with photography 15 years ago when I looked through the viewfinder of a friend's analog SLR. This experience has gripped me ever since and I bought my own SLR a couple of weeks later. Parallel to my university training I took classes in Photography and participated in a one year photographic program called 'Photoakademie'. That was the beginnin

Alden Hiltunen has been losing his eyesight for the past 25 years.

But two months ago, the 79-year-old man from Aura, Mich., had a telescopic lens implanted in one of his eyes, his grandson, Kyle Hamilton, told The Huffington Post in an email. The surgery, performed at the University of Michigan Kellog Eye Center, will allow Hiltunen to recognize facial details, read, and write, Yahoo Shine's Good News blog reported.

Though his vision is still fuzzy, earlier this week, Hiltunen decided it'd been far too long since he'd written his wife, Glenda, a love note. His message was short but sweet: "I love you, Glenda."

Hamilton, who posted a picture of the note to Reddit, told Yahoo that hi

To the unfamiliar passerby, Dobri Dobrev, 99, may come off as a haggard beggar who depends on the kindness of strangers to get by in life.

But, for the residents of Sofia, Bulgaria, Dobrev is nothing of the sort. Rather, the area’s fixture has been called a "saint" and a "divine stranger," according to a website dedicated to Dobrev.

Dobrev lost most of his hearing during World War II, according to Yahoo News Canada. He lives more than 15 miles outside of Sofia, a distance he used to trek by foot, but he now relies on the bus, according to SaintDobry.com. He spends his days asking people for money, but he doesn’t keep a cent.

The generous guy lives off of his monthly pension of 80 eu

Jf Pryor raised his hand in the air -- shot it up, really -- when he first saw a picture of Thor, a 2-year-old boxer-bulldog mix who was left to die on the streets of Rosarito, Mexico.

"It was like I was the biggest nerd sitting in front of the teacher, saying, 'Pick me! Pick me!'" Pryor told The Huffington Post. "I wanted that kid. I had to save him."

Thor is paralyzed in his hind legs. When a young woman first came across him on Jan. 15, he was dragging himself along a road, "infested, sick, and dying," Pryor said. She took a picture of him and sent it to a friend in animal rescue, who forwarded the email to Pryor. He, along with Nikki Audet, run The Mutt Scouts, a nonprofit dog resc

He lived on the same San Paulo street corner for 18 years. The black plastic bags wrapped around him and long tangled hair and beard protected him from the elements. Atop a small stool, this 75-year-old man could be seen every day, hunched over and writing.

Though homeless for 34 years, Raimundo (Portuguese for Raymond) was very well-read and loved to read.

In April 2011, he was befriended by a young woman named Shalla Monteiro, who was impressed by his poetry and wanted to help him realize his dream of publishing a book of his "mini-pages," as he calls them.

She created a Facebook Page to feature the writings of Raimundo Arruda Sobrinho, who signed every poem with a nickname he gav

Nearly 25 years after the Exxon Valdez oil spill injured wildlife off the coast of Alaska, a new report issued today by the U.S. Geological Survey indicates that sea otters have returned to pre-spill numbers within the most heavily oiled areas of Prince William Sound.

Sea otters in the path of the oil incurred heavy mortality when 42 million liters of Prudhoe Bay crude oil were spilled in Prince William Sound in March 1989, with an estimated loss of several thousand otters. Through long-term data collection and analysis, scientists found that sea otters were slow to recover, likely because of chronic exposure to lingering oil. Other studies documented persistence of oil in the sea otter’s

If you’ve run out of drinking water during a lakeside camping trip, there’s a simple solution: Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water.

In fact, an MIT team has discovered that this low-tech filtration system can produce up to four liters of drinking water a day — enough to quench the thirst of a typical person.

In a paper published this week in the journal PLoS ONE, the researchers demonstrate that a small piece of sapwood (the youngest wood of a tree which serves to move water up from the roots) can filter out more than 99 perc

While simply walking their dog in their backyard, a Northern California couple found $10 million in rare, mint-condition gold coins buried next to an old tree in their backyard. One of the rare coins is worth close to 1 million dollars.

Apparently in the gold rush of the 1800's, someone dug holes and buried their gold lute for safe keeping. The person may have died and the treasure lay for decades, waiting for someone to discover it after all those years.

A married couple in their middle years were walking their dog on their rural property in Northern California. They noticed a buried can sticking out of the ground near a tree.

They dislodged the unusually heavy can with a stick the

A U.S. based group called Wello has reinvented the wheel to help families in the developing world who don't have easy access to water.

Many people, including children, are spending a quarter to half of every day, hauling water on their heads. But, instead of carrying the heavy load, the Wello water wheel provides a way for anyone to easily transport 50 liters by rolling it.

Wello in 2011 worked in close collaboration with village residents in Rajasthan, India, to develop the concept, which won a $100,000 prize from Grand Challenges Canada.

"We designed our business model around extreme affordability. While similar products retail in the $75 to $100+ range, the WaterWheel will retail
