Flora & Fauna: World's oldest whale; all about potatoes; farming extracted land; everlasting lice; why play?

Sometimes seeing an old friend can warm the heart and encourage the spirit. "When Adam A. Pack, a marine mammal researcher, was photographing whales in Alaska’s Frederick Sound this July, he instantly recognized the flukes of an old friend," writes Emily Anthes of The New York Times. "The tail — mostly black, with a wash of white speckles near the edge — belongs to a whale named Old Timer. First spotted in 1972, Old Timer is now a male of at least 53 years, making him “the oldest known humpback whale in the world. . . The last time he had seen the whale, in 2015, was in the middle of a record-breaking, yearslong heat wave. . ."

Where would this country be without potatoes? It's a loaded question. Fluffed, whipped, baked, fried, scalloped, mashed, au gratin. . . Americans do love their taters. But U.S. scientists said, "It's not enough. . . Potatoes deserve more!" Jacob Bunge and Victor Stefanescu of The Wall Street Journal report, "Agriculture companies are applying cutting-edge genetic technology to the dusty brown tubers, aiming to grow bigger piles of spuds that could make for healthier potato chips and french fries. . .while grappling with storage and shelf life."

Not long ago, a coal mine sat on a blown-off mountaintop in West Virginia. The mine extracted that land's wealth and left it barren, but that is not the story's end. "The prospect of putting a farm on a former coal site is highly ambitious and pretty rare — at least in the mountainous Central Appalachian Coal Basin," report Even Andrew and Kristian Thacker of Ambrook Research. "Lavender, however, is a good match for mined terrain because it’s a relatively low-maintenance crop that thrives in dry, rocky soils. . . . But growing something, especially on reclaimed mine land, is a significant challenge."

What's grosser than gross? Lice. "We are in peak lice season, and the lice seem to arrive, always, at the moment when we are least equipped to deal with them. If you’ve endured them even once, odds are you still have at least a touch of lingering paranoia and phantom itching," reports Caitlin Gibson of The Washington Post. "They were there when Hannibal and his army crossed the Alps. They were there when both World Wars were fought. Now it is 2024, and we have Mars rovers and artificial intelligence and, still, lice. We can’t change the reality of them. Should we try to change the way we think about them?"

It's the Puppy Bowl! The Kitten Bowl! The Turtle Bowl. OK. May there's no turtle bowl -- yet. But humans do love to watch animals play. Why? As David Toomey writes for The Conversation, "Play has a role in Darwin’s theory of natural selection. As I explain in my new book, Kingdom of Play: What Ball-bouncing Octopuses, Belly-flopping Monkeys, and Mud-sliding Elephants Reveal about Life Itself, there are many similarities – so many that if you could distill the processes of natural selection into a single behavior, that behavior would be play, Animals forage and hunt in specific ways that don’t typically change. But an animal at play is far more likely to innovate – and some of its innovations may in time be adapted into new ways to forage and hunt."

While the Florida Everglades are home to an abundance of animal diversity, including 360 different species of birds and countless insect species, Burmese pythons are not a welcome addition. The state has battled to control the invasive, nonnative snake's spread with multiple approaches, including capture and kill contests. The state just wrapped up its annual Florida Python Challenge "during which time participants caught and killed the nonvenomous constrictors, which feed on the state's native fauna," reports Joe Hernandez of NPR. Florida offers more opportunities to remove pythons year-round.
