Finding a rare or unusual coin in the spare change you receive from your local grocery store, gas station, or restaurant may sound a little far-fetched and even absurd. However, don't rule out the possibility, at least until the over one million collectible coins given to retailers across the country by US coin dealers in honor of the 96th National Coin Week (April 21, 2019 to April 27, 2019), have been discovered. Called the Great American Coin Hunt, this first-of-its-kind treasure hunt is designed to inspire a new generation of kids and adults to start coin collections of their own....

Paleontologists had long believed that ancient humans used land bridges to migrate from one country to another. Hence, Luzon, the largest of the 7,641 islands that comprise the Philippine archipelago in the Western Pacific Ocean, appeared to be entirely out of reach for our ancestors. Now, there is evidence that a previously unknown human species managed to overcome the ocean currents and settle on the island between 50,000 and 67,000 years ago — around the same time as our species, the Homo sapiens and our closest ancestors, the Neanderthals, dwelled on Earth....

Researchers have long known that the ancestors of the mighty whales were nimble, four-legged creatures that were comfortable both on land and in the sea. However, given that the only evidence of the early mammals had been found in present-day Pakistan, India, and parts of Africa, scientists were unsure of how the mammals had dispersed to the Western Hemisphere. Now, thanks to the aptly-named Peregocetus pacificus (P.pacificus), or "traveling whale that reached the Pacific," paleontologists finally have an answer to this all-important migration mystery....

Looking for a fun Earth Day activity? You may want to try plogging, or picking up litter while jogging. Odd as it may sound, the new "sport" is becoming extremely popular with runners worldwide, many of whom are posting images of themselves and friends holding bags of trash on social media....

After almost twenty years in space — thirteen of which were spent making extraordinary discoveries about the Saturn system, including its rings and natural satellites — NASA's Cassini spacecraft finally ran out of fuel. However, shortly before plunging into Saturn's atmosphere on September 15, 2017, the probe completed one final important mission: six close flybys of tiny moons located inside, or near, Saturn's rings....

Over the years, NASA has successfully deployed several rovers, landers, and orbiters to Mars. While the science laboratories continue to provide invaluable data about the Red Planet, their limited, or zero — as is the case with landers — mobility, restricts the space exploration vehicles to areas close to the original landing site. To obtain a more comprehensive view of Mars, the US Space Agency plans to send a fully-autonomous miniature test helicopter with the Mars 2020 rover, scheduled for launch in July 2020....

Termites are famous for their superior architectural skills. The mounds created by the industrious insects contain an elaborate network of tunnels with a series of chimneys that help regulate oxygen levels, temperature, and humidity to ensure the queen, who sits in a chamber underneath, is comfortable....

For pranksters and joke lovers, there is no better day than April 1. Often called April Fools' Day, it is the one day of the year when light-hearted tricks are not only expected but also welcomed by all. Some believe the fun holiday began in 1582 when the world transitioned from the Julian calendar, which celebrated the New Year on the last week of March, to the current Gregorian calendar. Those unaware of the change, or refusing to accept the January 1 start date, were often mocked and had jokes played on them on or around the old New Year. Others speculate the holiday began as a joyful way to welcome spring....

When a university intern stumbled upon a seven-foot fish washed up on the beach at the University of Santa Barbara's (UCSB) Coal Oil Point Reserve on February 19, 2019, scientists assumed it was the mola mola sunfish. One of the world's heaviest known bony fishes, the species, found in tropical and temperate waters around the globe, is common in the Santa Barbara Channel....

Need a reason to smile? Then you will be happy to know that today, March 20, 2019, is not just the first day of spring, but also the International Day of Happiness. Established by The United Nations (UN) in 2012, it is meant to remind us that happiness is an essential human goal and right. This year's theme, Happier Together, encourages people worldwide to focus on what we have in common, rather than what divides us....

What better way to welcome spring than by dousing yourself and your friends with vibrant colored powder? That is the essence of the popular Indian festival of Holi. Observed annually on the last full moon day of the Hindu lunar month, Phalguna, this year, the fun event will be celebrated on March 21, 2019....

In early February 2019, 51-year-old Rainer Schimpf and his team set out to film South Africa's famous Sardine Run off the coast of Point Elizabeth. The annual migration of billions of Sardinops sagax, more commonly known as South African pilchards or sardines, is a big draw for predators, especially the Cape gannet, a beautiful, cream-colored seabird, and the common dolphin. The two species work together to herd the large group of fish and separate them into smaller shoals known as bait balls, which are then scooped up by not just the birds and the dolphins, but also other hunters such as copper sharks and Bryde's whales....

Carbon dioxide (CO2), released by activities like burning of fossil fuels such as coal, oil, and natural gas, is one of the biggest contributors to the greenhouse effect, responsible for global warming. Over the years, scientists have come up with several innovative solutions to capture the polluting gas. However, none have been practical enough to implement on a large scale. Now, researchers at RMIT University in Melbourne, Australia believe they may have finally found a feasible way to reduce atmospheric CO2 – turning the gas back into coal!...

Shelby, who plays Bella in the recent Sony Pictures release A Dog’s Way Home, has all the traits of a celebrity pooch: bright, golden eyes, expressive eyebrows, and a big, brown nose. However, the pit bull mix did not always seem destined to be a movie star. About two years ago, Shelby was a stray puppy who lived on the streets and spent her days digging through trash for food scraps....

Virgin Galactic's founder, Sir Richard Branson, has been hoping to make space tourism a reality since 2008. While it has taken a little longer than the 18 months he had originally estimated, the company is getting increasingly closer to accomplishing its mission. On December 13, 2018, Virgin Galactic's suborbital spaceliner, VSS Unity, made history with the longest rocket-powered flight when it soared to the edge of space, 51.4 miles (82 km) above sea level. On February 22, 2019, the aircraft repeated the feat, this time with its first passenger – the company's astronaut trainer Beth Moses - on board....

Experts estimate that Earth gets bombarded with thousands of pieces of cosmic debris each year. While most burn up in the atmosphere, a few hundred survive and hit the planet's surface annually. While the impact of the space rocks, which come hurtling down at rapid speeds, has thus far been minimal, the possibility of an asteroid landing in a densely populated area and causing severe damage cannot be ignored....

The severe winter storm that pummeled parts of Washington, D.C. with as much as six inches of snow on February 20, 2019 had most residents scrambling for the safety and warmth of their homes. However, Smithsonian's National Zoo's giant panda Bei Bei was not among them. The adorable three-year-old had the time of his life playing in the mounds of fresh powder that helped Washington, D.C. retain its stature as the snowiest major city on the US East Coast this year....

Always wanted to experience the magical winter wonderland that Queen Elsa created in Disney's animated movie Frozen? Then you are in luck. Thanks to Utah-based company “Ice Castles,” acre-sized frozen fortresses are now a reality in six of North America's coldest regions: Dillon, CO, Excelsior, MN, Lake Geneva, WI, North Woodstock, New Hampshire, Midway, UT and Edmonton in Alberta, Canada....

Last week’s record-breaking cold snap, which brought many US cities to a standstill, finally ended on February 2, 2019. Residents all the way from southern New England to the Upper Midwest breathed a sigh of relief as temperatures rose to a “balmy” mid-40s and low 50 degrees Fahrenheit. Even better, that same day, world-famous groundhog Punxsutawney Phil failed to see his shadow, which means that spring is a mere six weeks away!...

This year’s winter has been particularly harsh on the residents of the central and eastern United States, who have had to endure an abnormally cold weather pattern since the second week of January. Unfortunately, things are going to get even worse starting Tuesday, January 29, 2019. According to the National Weather Service (NWS), the extreme Arctic cold sweeping across the Midwest and Great Lakes will result in dangerously cold wind chills and cause temperatures in some cities to drop to their lowest levels in over two decades....

On Sunday, February 3, 2019, over 180 million Americans will tune in to watch Super Bowl LIII. While the National Football League Championship game between the Los Angeles Rams and the New England Patriots certainly promises to be interesting, for most people, the day provides an excuse to host parties, mingle with friends and family, and indulge in foods they would usually avoid, or at least not consume with such abandon. It is, therefore, not surprising that Super Bowl Sunday ranks as one of the country’s biggest food consumption days — second only to Thanksgiving....

Those concerned that robots are taking over the world can rest easy – for now. Though the androids have proved useful at performing mundane tasks, they are not ready for prime time. At least that appears to be the case at Japan’s cutting-edge Henn-na Hotel chain, where over half of the robot staff is being replaced by humans....

A giant spinning wheel of ice on the surface of the Presumpscot River has enthralled crowds in Westbrook, Maine since Monday, January 14, 2019. Many locals have likened it to crop circles –strange patterns that appear mysteriously overnight in farmers' fields, which have long been theorized to be markers of extraterrestrial communication – and speculated that the icy ring is a landing site for an alien ship. Unfortunately for UFO enthusiasts, experts say that the rare winter phenomenon is a natural occurrence....
