Japanese Scientists Find Mutant Butterflies Near Fukushima

Japanese scientists have looked at several generations of butterflies near the power plant and found some concerning "abnormalities."

A massive release of radioactive material is never good, but so far it's been hard to evaluate the precise effects of the collapse of the Fukushima Dai-ichi nuclear power plant on the surrounding environment. But this new study, published in Scientific Reports, is concerning. Japanese scientists have looked at several generations of pale grass blue butterfly populations in the affected area and have found physical mutations and genetic damage. In short: mutant butterflies.


From Yale e360:

...butterflies collected from the Fukushima area about two months after the 2011 accident were more likely to have leg, antennae, and wing shape mutations than those found elsewhere [and] butterflies found in areas with higher levels of radiation developed much smaller wings and eye irregularities. After breeding these butterflies in a laboratory, researchers found the next generation had numerous abnormalities not seen in the previous generation, including malformed antennae. And adult butterflies collected near Fukushima six months after the initial tests were more than twice as likely to have mutations than those found soon after the accident.

So in other words, the radiation caused mutations in the butterflies that were directly exposed, and the rate of mutations actually increased in their offspring.

These butterflies are especially good indicators of the effects of radiation, the study's authors explain, because they're widespread in Japan, making comparisons easy, and their wing colorations are especially sensitive to environmental changes.

Here are some "representative abnormalities" of butterflies they caught near Fukushima, including malformed wings and dented eyes.

The authors stop short of speculating what this might mean for other animals (like humans), and I'm not even sure what the worst case scenario is here. Let's call it a cause for concern.

National Tell a Joke Day dates back to 1944 when President Franklin Delano Roosevelt was having a meeting with Vice-President, Henry Wallace. The two men were tired and depressed due to the stress caused by leading a country through world war.

During a lull in the meeting, Wallace said, "Frank, to cheer you up I have a joke I'd like to share."

"Let's have it, Henry," Roosevelt replied while ashing his cigarette.

"Why did the chicken cross the road?" Wallace asked. "Not sure," Roosevelt replied.

"To get to the other side," Wallace responded.

Roosevelt laughed so hard that the bourbon he was drinking sprayed out of his nose and onto the floor of the oval office.

The joke was so funny, and did such a great job at lightening both their moods, Roosevelt proclaimed that every year, August 16 would be National Tell a Joke Day.

Just kidding.

Nobody knows why National Tell a Joke Day started, but in a world where the President of the United States is trying to buy Greenland, "Beverly Hills, 90210" is back on TV, and the economy is about to go off a cliff, we could all use a bit of levity.

To celebrate National Tell a Joke Day, the people on Twitter responded with hundreds of the corniest dad jokes ever told. Here are some of the best.

The Judean date palm was once common in ancient Judea. The tree itself was a source of shelter, its fruit was ubiquitous in food, and its likeness was even engraved on money. But the plant became extinct around 500 A.D., and the prevalent palm was no more. But the plant is getting a second chance at life in the new millennium after researchers were able to resurrect ancient seeds.

Two thousand-year-old seeds were discovered inside a pottery jar during an archaeological excavation of Masada, a historic mountain fortress in southern Israel. It is believed the seeds were produced between 155 B.C. and 64 A.D. Those seeds sat inside a researcher's drawer in Tel Aviv for years, not doing anything.

Elaine Solowey, the Director of the Arava Institute for Environmental Studies at Kibbutz Ketura in Israel, wondered if she could revive the Judean Date Palm, so in 2005, she began to experiment. "I assumed the food in the seed would be no good after all that time. How could it be?" Solewey said.

There's been an uptick in fake emotional support animals (ESAs), which has led some airlines to crack down on which animals can and can't fly. Remember that emotional support peacock?

But some restrictions on ESAs don't fly with the Department of Transportation (DOT), leading them to crack down on the crack down.

Delta says that there has been an 84 percent increase in animal incidents since 2016, thanks in part to the increase of ESAs on airplanes. Last year, Delta airlines banned pit bulls and pit bull-related dog breeds after two airline staff were bitten by the breed while boarding a flight from Atlanta to Tokyo.

"We must err on the side of safety. Most recently, two Delta employees were bit by a pit bull traveling as a support animal last week. We struggled with the decision to expand the ban to service animals, knowing that some customers have legitimate needs, but we have determined that untrained, pit bull-type dogs posing as both service and support animals are a potential safety risk," Delta told People regarding the new rule.

Trying to get one dog to sit still and make eye contact with a camera for more than half a second is a low-key miracle. Lining up 16 dogs, on steps, and having them all stare at the camera simultaneously is the work of a God-like dog whisperer.

This miracle worker is Liam Beach, a 19-year-old animal management graduate from Cardiff, Wales. A friend of his dared him to attempt the shot and he accepted the challenge.

"My friend Catherine challenged me to try to get all of my lot sat on the stairs for a photo. She said, 'I bet you can't pull it off,' so I thought 'challenge accepted,'" he said, accoriding to Paws Planet.

Americans on both sides of the political aisle can agree on one thing: our infrastructure needs a huge upgrade. While politicians drag their feet on high-speed rail projects, fixing bridges, and building new airports, one amazing project is picking up steam.

The Great American Rail-Trail, a bike path that will connect Washington state to Washington, D.C., is over 50% complete.

The trail is being planned by the Rails-to-Trails Conservancy, a nonprofit that is working with local governments to make the dream a reality.
