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."
