Last week, a runner traversing the trails of California’s Pinnacle National Park, encountered a mesmerizing sight — a halo of rainbow colors emanating from the single cloud in the clear blue skies. While the phenomenon is commonly referred to as a “fire rainbow,” researchers say the name is misleading since the optical illusion is neither a rainbow, nor does it have anything to do with fire!...

While birds may appear to flutter about in the world, magically finding their way to food and other members of the flock, the reality is, species migrate to the same destination, time and again. Over the years, researchers have established that the animals use Earth’s magnetic fields as guides. However, how they sense these fields has been a mystery....

Pet owners usually have no choice but to implant their cats or dogs with microchips to help identify the animals if they get lost or decide to escape. However, one Siberian Husky in Israel did not need the modern technology — he could sing his way home!...

When the 2018 March Madness — the NCAA Division I Men's Basketball Tournament — began, Pizza Hut knew that avid fans wouldn’t want to miss a second of the games. So, for the second consecutive year, the company partnered with custom sneaker designer Dominic Chambrone, aka “The Shoe Surgeon,” to create stylish footwear that could be used to order pizzas. Dubbed Pie Tops II, the limited high-tops were available in two different colors: a red version to match Pizza Hut’s signature red logo and a more neutral tan color to emulate the pizza crust....

In case you missed it, April 5 was National Caramel Day. To mark the holiday, which honors the soft sugary confection, August Storck KG, manufacturer of the popular caramel-flavored Werther’s Original candy, teamed up with toymaker Hasbro to create a life-size version of Candy Land. Open only for the day from 10 a.m. to 6 p.m., the massive game board, located on the Santa Monica Pier in Santa Monica, California, was completely free for fans of all ages to enjoy....

Experts estimate that by the year 2050, the world’s population will swell from the current 7.3 billion to over 9.5 billion, with just nine countries accounting for half the growth. If accurate, conventional farming methods, which revolve around growing one or two crops annually, will be unable to sustain the increase in food demand. Now, some Australian scientists may have found a way to cost-effectively accelerate crop yields with a technique called speed breeding, inspired by NASA’s experiments to grow wheat in space....

Though many artists specialize in cityscapes very few create masterpieces as detailed and intricate as those sketched by Stephen Wiltshire. Even more impressive is that each monochromatic landscape, which takes the British artist just a few days to complete, is drawn entirely from memory, a talent that has earned him the nickname “The Human Camera.”...

Experts predict myopia, or nearsightedness, will reach epidemic proportions by the end of the decade, with over a third of the world’s population requiring glasses or contact lenses. However, if a team of Israeli ophthalmologists from Jerusalem’s Shaare Zedek Medical Center has their way, the crisis may be averted with special “nanodrops” created to correct refractive errors responsible for nearsightedness (myopia), farsightedness (hyperopia), or blurred vision (astigmatism)....

Though the harmful effects of plastic on wildlife and human health are well-documented, the versatile material is hard to avoid. Nearly everything we touch, from grocery bags to drink bottles to food packaging, contains plastic. Now, Amsterdam’s Ekoplaza supermarket is making it a little easier for consumers to reduce consumption of single-use bags and containers, which are clogging our landfills at alarming rates, with a dedicated plastic-free aisle. Believed to be the world’s first, it features 700 products, including rice, beans, yogurt, chocolate milk, cereal, snacks, and even meat....
