Carole Morison in the now-famous Food, Inc. scene.

Twelve minutes into the 2009 documentary Food, Inc., Carole Morison appears on the screen -- haggard, tired, quietly seething. Squinting into the sun, she tells the camera, “I’ve just made up my mind; I’m gonna say what I have to say,” and she proceeds to show and tell.

Wearing a face mask, she steps inside one of her chicken houses, where she is raising broilers for Perdue. Inside she reveals a crowded sea of birds bumping into each other and squawking in agitation. Chickens are shown taking a few steps and falling down -- due to the weight they’ve been bred to put on rapidly. Others are on their backs, gasping for breath inside a chicken house they cannot leave. Carole picks up a few dead birds and throws them in a pile.

She walks back outside, removes her face mask, wipes the dust off her face, and says with disgust, “That’s normal.”

But it’s far from normal today. Carole Morison is still stepping into her chicken houses in Pocomoke, Md., but now the chickens follow her. Rather than flee, they try to roost on her shoulder. Now she doesn’t have to wear a face mask, and she’s hopeful that she may be able to take antibiotics again after years of developing allergies while using Perdue’s antibiotic-laden feed. And in a widely circulated photograph taken for Flavor magazine, she looks 10 years younger than she did in the movie.

Carole today, managing the new farm's pasture.

“Everybody tells me that!” she said in a recent phone interview. "I just look at the new photo and say, man, I need to get my hair cut.”

Last year, in an inspiring turnaround, Carole and her husband, Frank, launched a pastured egg operation on their Bird’s Eye View Farm. When Perdue terminated their contract just before Food, Inc. was released (the reason given was Carole’s refusal to use dark, tunnel-ventilated chicken houses), it seemed unlikely they’d ever get back into farming. On the Delmarva Peninsula, nestled between the Chesapeake Bay and the Atlantic, the vast majority of chicken farmers work for big agribusiness, entering into contracts in which they don’t own the birds or have much say in their raising, but are expected to invest in the expensive infrastructure to house and feed them. Carole wasn’t about to do that again.

Off the coast of Brazil, dolphins and humans have been working together to snare mullet since 1847. Ed Yong reports at Discover Magazine:

The dolphins drive the mullet towards the fishermen, who stand waist-deep in water holding nets. The humans cannot see the fish through the turbid water. They must wait for their accomplices.

As the fish approach, the dolphins signal to the humans by rolling at the surface, or slapping the water with their heads or tails. The nets are cast, and the mullet are snared. Some manage to escape, but in breaking formation, they are easy prey for the dolphins.

Apparently this adorable bike-guarding dog lives in Nanning, China, where he's known as Li Li the Bike Hugging Dog.

I heard this weekend that there's at least one coyote living permanently in Central Park. Everyone's heard a story like that recently -- bears, coyotes, and other carnivores stalking through city streets and parks, right where we'd least expect them. But according to a new study, certain carnivores -- raccoons and coyotes -- do better in cities than in rural areas. Conservation Magazine reports:

One team found seven times more coyotes per square kilometer in urban parts of southern California than rural areas, and raccoons have reached an “astonishing” 333 animals per square kilometer in one Fort Lauderdale, Florida park, about four to 400 times their density in the countryside.

Jean-Marie herds goats within the Louisville city limits. He sells them to the growing immigrant and refugee populations. Goat isn't yet popular with all Southerners, but it reminds Jean-Marie of his home in Burundi.

It's hard to imagine a teensy mosquito taking down an animal as mighty as the killer whale. Yet that's exactly what some folks suspect happened at two SeaWorld locations.

Representatives from the Whale and Dolphin Conservation Society (WDCS) say that orcas that died at SeaWorld parks in Orlando and San Antonio succumbed to encephalitis, a virus transmitted by mosquitoes.  WDCS argues that these deaths could have been avoided if whales weren't kept in captivity.

Use pesticides on a field for long enough and the bugs that you're supposed to be defeating will adapt. But you know what adapts faster than bugs? Bacteria. They can run through multiple generations in a day or so, and a new study shows that when bugs team up with a certain pesticide-loving bacteria, the bugs, too, can develop resistance to pesticides incredibly quickly.

It appears the bulk of Burger King's pork is currently being served at breakfast, but there are plans in the works for a pulled pork sandwich from the chain. (Photo by Mark H. Anbinder.)

As of today, Burger King is calling itself the “first U.S. national chain to pledge cage-free pork and eggs.”

Never heard of “cage-free pork”? Neither had I. In fact, I’m guessing that the PR executives at Burger King may have invented it. There are cage-free eggs, yes. That term refers to eggs from chickens that are raised outside of tiny battery cages (the industry standard), but are still in confinement.

As the AP article makes clear, Burger King is referring to pork raised without gestation crates -- a practice of confining pregnant sows to spaces roughly the width of their own bodies that has long been considered the worst of the worst when it comes to animal husbandry. So yes, the pigs will be free of a certain kind of cage, or pen. Does that mean they won’t live in concentrated animals feeding operations (CAFOs)? Unlikely.

No doubt adding in “cage-free pork” beside the eggs seemed like a nice way to streamline Burger King’s big headline. And like the term “free-range” (which itself has no legal meaning and is now used solely for marketing purposes), cage-free sounds so humane, doesn’t it?

Not that we can chalk this whole announcement up to humane-washing.

Imagine if your body could tell you where and when a certain chemical is impacting your health. Scientists at the University of Exeter have done just that -- with green-glowing zebrafish, that is.

Researchers genetically engineered young zebrafish to produce a fluorescent glow in the presence of hormone-disrupting chemicals like bisphenol-A. By exposing fish to endocrine disruptors and observing when individual body parts light up, researchers can learn exactly how and at what concentrations these chemicals impact various organs and tissues. They can then make certain inferences on how endocrine disruptors impact human health.

For instance, observing the glowing fish confirmed previous findings, such as a link between bisphenol A and heart problems.

"We do see in this fish that the heart glows particularly in response to bisphenol A," Charles Tyler, the study's leader, said. "So we can target the heart and try to look at the mechanics of what is happening."

What's black and white and so cute you'll want to squeal like a Bieber-obsessed tween? A baby panda. And now you can see one any time you want.
