A collection of 1,000 prehistoric structures dubbed mustatils — the plural form of the Arabic term for rectangles — scattered across 124,274 miles (200,000 kilometers) in northwest Saudi Arabia may be the world's oldest monuments. A team of archeologists from the University of Western Australia (UWA) reached this conclusion after radiocarbon dating of charcoal found inside the courtyards indicated they were constructed in 5,000 BC — or about 2,000 years before the Egyptian pyramids or monuments like Stonehenge in southern England.
Since landing on Mars on February 18, 2021, NASA's Perseverance rover has achieved numerous "firsts," including beaming audio sounds from the Red Planet's surface. It also made history as the first spacecraft to record sounds from another spacecraft — the Ingenuity helicopter — on another planet.
When Jennifer Johnson and her team embarked on their annual quest to survey the sturgeon population in the Detroit River in mid-April 2021, they had fully expected to find some super-sized specimens. However, the U.S. Fish and Wildlife Service biologists had never anticipated luring in the granddaddy of all sturgeons — a massive, 240-pound, 6-foot, 10-inch long fish that they estimate is at least a century old!
Every year, on the second Sunday of May, Americans show their appreciation for the real-life heroes in their lives — moms — with special treats and lavish gifts. This Mother's Day will be no exception. A National Retail Federation (NRF) survey of 7,818 people revealed that the approximately 83 percent of US adults who plan to celebrate the holiday on May 9, 2021, will each spend an average of $220.48. The total, an astounding $28.1 billion, is the highest amount in the survey's 18-year history and easily topples 2020's record spend of $26.7 billion.
The annual 3-to 4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as vulnerable as the Republic of the Maldives, a collection of more than a thousand picturesque islands in the Indian Ocean. NASA researchers believe that parts of what is "arguably the lowest-lying country in the world" will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To combat the inevitable, the government recently unveiled plans for the world's first "true" floating island city.
British sculptor Jason deCaires Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has submerged over 850 massive artworks in numerous site-specific "sculpture parks" worldwide. On February 1, 2021, Taylor unveiled his latest endeavor — The Underwater Museum of Cannes.
Regeneration, or the ability to regrow body parts, is a fairly widespread phenomenon in the animal kingdom. However, the skill is usually restricted to growing a new tail or a new limb. Now, researchers have found two species of sacoglossan sea slugs — Elysia atroviridis and Elysia marginata — that deliberately detach their heads from their original bodies and grow brand new ones!
The beauty of love is that it can happen with the most unexpected person in the most unlikely of places. In the case of a one-year-old stray puppy in Duplin County, North Carolina, that "person" happened to be a bright purple stuffed unicorn at a local Dollar General store. The good news is that this unusual love story has a happy ending!
