The quarter dollar is both the most commonly-used coin in the American currency and the most unique. Since 1999, the coin's reverse, or "tails," side has showcased all 50 US states, as well as the breathtaking beauty of the country's national parks. Now, the US Mint plans to use the silver canvas to celebrate female leaders who have played a crucial part in shaping the nation's history.
Memorial Day, which will be celebrated on May 31, 2021, is one of the most important American holidays. Observed annually on the last Monday of May, it honors the brave men and women of the US Army, Navy, Marine Corps, National Guard, Air Force, and the Coast Guard who sacrificed their lives to defend America's freedom. Meanwhile, Veterans Day, which takes place each year on November 11, honors all veterans — living or dead—but mainly gives thanks to living veterans who served their country honorably during war or peacetime.
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.
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!
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.
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!
When 36-year-old Andy Duran decided to return to his favorite high school hobby — skateboarding — in January 2021, the only obstacle he expected to encounter was his own ability to get back into the sport after the long hiatus. However, the 340-pound skateboarder from Oakland, California, soon realized that was the least of his problems.
