Flora & Fauna: Axolotl is the 'comeback king;' corn seed miracle; big snake haul; two-note song; tracking butterflies

Limb regeneration may sound like an 'X-Files' episode, but U.S. scientists are working on it. "With a silly smile and frilly gills, the axolotl has wriggled its way into the hearts of millions," reports Dino Grandoni of The Washington Post. "But this adorable species of salamander is also helping researchers investigate a serious medical mystery: Could the human body be coaxed to regrow a severed arm or leg? Scientists are turning to the axolotl because it is an expert at regeneration. . . .The species is also a comeback king, able to regrow not only lost limbs but also tissue in the heart, lungs and even the brain."

It's hot and humid, and corn tasseling season is almost here. "If someone writes a book about the 'seven great wonders of agriculture,' tasseling and pollination must be on the list," reports Tom J. Bechman of Farm Progress. "The process of producing hundreds of new corn kernels per plant, all from one original seed, is simple yet complex at the same time." Read how the miracle of corn happens here.

'Snakes on a Plane' might be a good summer movie fun, but in Florida, hundreds of people drop the film drama and eradicate snakes on land. "It was a milestone moment in Florida’s 25-year war on invasive Burmese pythons: an eye-popping announcement that biologists had removed 20 tons of the slithering invaders from waters in and around the Everglades in little more than a decade, as well as shattering their previous record for a single-season haul," reports Richard Luscombe of The Guardian. "The successes of the team at the Conservancy of Southwest Florida showcase the progress that has been made in efforts to reverse the snakes’ takeover of the state’s natural wilderness."

Two notes + Razor-sharp teeth = One summer blockbuster. “Da, duh. E and F have become synonymous with tension, fear and sharks, representing the primal dread of being stalked by a predator," writes media history scholar Jared Bahir Browsh for The Conversation. "Fifty years ago, Steven Spielberg’s blockbuster film – along with its spooky score composed by John Williams – convinced generations of swimmers to think twice before going in the water. . . . I decided to take a deeper dive into the staying power of these two notes. . . "

If you want to help the world be a better place for all creatures, then do one small thing to help insects: Provide an insect-friendly habitat. "This includes supporting a variety of native plants that can provide both nectar and leaves, which are food for many herbivorous insects throughout their lives. A good habitat also provides places for insects to nest, such as bare ground or leaf litter. Bigger patches are better, but even small gardens can be helpful," write Christopher Halsch and Eliza Grames for The Conversation. "At the same time, limiting exposure to other threats is important. Actions such as dimming artificial lights at night and reducing the use of pesticides can help."

How can the fluttering trails and migrations of butterflies be traced and mapped? With pollen. "Those tiny pollen grains are helping researchers study a process that until now has been largely inscrutable: the migratory patterns of insects as they move around the globe," reports Saugat Bolakhe for Knowable magazine. "Analyzing pollen collected from 264 butterflies from 10 different countries . . researchers identified 398 different plants they could use to track the butterflies’ movements."

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?"

Like everything Mother Nature imbues, play has purpose.

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.
