Though it is now arid, the Urumaco region in Venezuela's Falcón State was once a mega wetland that was home to numerous colossal animal species. These included rodents the size of modern-day buffaloes and 10-foot (3-meter) tall carnivorous birds. The latest to join the list of the area's massive creatures is a giant turtle that was 100 times larger than its closest living relative, the Amazon river turtle, and about 1.5 times the size of the world's largest living turtle, the marine leatherback....

Need an extra day to catch up on sleep or to finish an assignment this month? Then you are in luck, because 2020 is a leap year, an event that occurs once every four years. This means that instead of the customary 365 days, the year will have 366 days. Since the extra day is tacked onto the shortest month of the year, February 2020 will have 29 days....

Though there are numerous dog shows held around the US every year, none are considered as prestigious as the Westminster Kennel Club Dog Show. Now celebrating its 144th year, the "Super Bowl" of the canine world, is America's oldest dog show. This year's event, which took place at New York City's Madison Square Garden from February 8 to 11, 2020, attracted 2,500 competitors representing 204 breeds from 49 states and 19 countries....

In what can only be described as an extraordinary engineering feat, NASA scientists have remotely fixed a software glitch on the Voyager 2 probe, which lies 11.5 billion miles away at the edge of a transitional region of space. Known as the heliosphere, it is a vast, bubble-like area that surrounds the Sun and the Solar System....

A shark that walks in water instead of swimming might sound like a creature straight out of a science fiction thriller. However, that is precisely how the four new species of the fish — found in the tropical waters of the Indo-Australian archipelago — move across the seafloor. The unique ocean dwellers were discovered by a team of scientists, led by Dr. Christine Dudgeon from Australia's University of Queensland, during a 12-year global conservation study....

Amid the excitement of Super Bowl LIV, which ended with the Kansas City Chiefs' first championship title in fifty years, it may have slipped your mind that yesterday was Groundhog Day. Observed annually on February 2, the fun North American tradition stems from the Pennsylvania Dutch superstition that if a groundhog, emerging from its burrow, sees its shadow, winter will continue for six more weeks. Conversely, the animal's failure to observe one indicates that spring is around the corner....

For those unfamiliar with the sport, the National Football League's (NFL) championship game, aka the Super Bowl, may seem like an ordinary season finale. However, don't tell that to the 194 million Americans who plan to watch the San Francisco 49ers and Kansas City Chiefs battle it out for the coveted Vince Lombardi Trophy at the Hard Rock Stadium in Miami Gardens, Florida, on February 2, 2020....

When 17-year-old Wolf Cukier accepted an internship at NASA's Goddard Space Flight Center in Greenbelt, Maryland, last summer, he expected to be challenged and gain insights into pursuing a career in astrophysics. Instead, the high school junior from Scarsdale, New York, attained worldwide fame for an achievement that eludes most astronomers — finding a new planet! Even more impressive, Cukier made the discovery on the third day of his two-month-long internship at the US Space Agency....

The Earth's inner core, which boasts temperatures exceeding 9,000 degrees Fahrenheit (5,000 degrees Celsius), may not evoke images of a winter wonderland. Yet, a new study by a team of scientists led by Youjun Zhang, an associate professor at Sichuan University in China, asserts that the deepest part of our planet may be covered with a 200-mile-thick layer of "snow." However, before you rush to pack your skis, be aware that the "snowflakes" are not composed of frozen water crystals, but of tiny particles of iron!...

Cotton candy is probably the last thing that comes to mind when one thinks of exoplanets. But the three giant worlds orbiting the Kepler 51 star system, about 2,600 light-years away from Earth, are so "light and fluffy" that they warrant a comparison to the beloved spun-sugar confection....

With no brains or nerve cells, single-cellular microorganisms are often regarded to be simple, primitive beings with few capabilities. However, a new Harvard University study suggests that protozoans, like Stentor roeselii, have the smarts to make "complex" decisions when confronted with unpleasant situations....

Happy 2020! At the stroke of midnight on December 31, 2019, cities worldwide rang in both a new year and a new decade with dazzling fireworks shows. Here are some of this year's most spectacular displays from around the world....

Christmas is all about observing beloved traditions. For some, this means attending midnight mass on Christmas eve, for others, it entails watching reruns of old classics like Elf and Home Alone. Then there are the millions for whom the holiday is incomplete without an episode of The Yule Log — a four-hour television show featuring a warm, crackling fire....

Hanukkah is one of the most anticipated and joyous of all Jewish festivals. Although the celebration always begins on the 25th day of Kislev, the ninth month on the Hebrew calendar, that date can fall anywhere between late November and late December on the Gregorian calendar. This year, the eight-day festival will begin at sundown on December 22, 2019, and continue through December 30, 2019....

Time Inc.'s "Person of the Year" tradition began in 1927, when the magazine commemorated 25-year-old aviator Charles Lindbergh for the first nonstop solo flight across the Atlantic Ocean. Though the media franchise has since recognized several young people for their global influence, it has never given the important distinction to a teenager. But then again, few teens are as passionate about their mission as 2019's "Person of The Year"— 16-year-old Swedish climate change activist Greta Thunberg....

It is often said that "a picture is worth a thousand words." That is certainly true of the mesmerizing images of fleeting moments of nature submitted by international ecologists and students for the British Ecological Society's (BES) annual photography competition. Here are a few of 2019's winning entries, announced on November 28, 2019....

While America's highest office — the presidency — remains elusive to women, Finland has just elected its third female premier. Even more impressive, 34-year-old Sanna Marin, who was sworn into office on December 10, 2019, is the youngest prime minister in Finland's history, and the world's youngest sitting government head. Prior to this, that honor belonged to New Zealand's Jacinda Ardern, who was 37 years old when she took office in October 2017....

On December 7, 2019, David Datuna was admiring the modern and contemporary works of art on display from 200 of the world's leading galleries at Miami's Art Basel, when hunger pangs hit. Fortunately for the New York-based artist, there was a ripe banana just waiting to be eaten. The only problem? The tropical fruit stuck to the wall with duct tape was no ordinary banana — it was an art installation that had just been sold by Perrotin, an international art gallery, for $120,000!...

To say that space is tight in the Principality of Monaco is an understatement. The pint-sized country, which has a surface area of just 0.78 square miles (2.02 square kilometers), boasts a total population density of 48,466 people per square mile — the highest in the world. With building space stretched to the limit, architects in the world's second-smallest country have been constructing up towards the sky, tunneling down into the ground, and even carving out the surrounding cliffs. Now, they have built a multi-million dollar luxury home inside a rock....

Though it has been over a century since the R.M.S. Titanic sank after hitting an iceberg, modern-day ships remain as vulnerable to such catastrophes. The most recent disaster occurred in May 2019, when a sightseeing boat on the Danube River in Hungary capsized and sank after colliding with a river cruise ship, killing 28 of the 35 tourists aboard. Now, researchers from New York's University of Rochester may have found a way to avert such tragedies, with a water-repellant metal that can stay afloat even after having several holes drilled in it....

Celebrated annually on the Tuesday after Thanksgiving and the popular shopping events Black Friday and Cyber Monday, #GivingTuesday is designed to kick off the season of generosity. Now in its eighth year, the charitable event uses the power of social media to encourage organizations and individuals to donate funds or resources towards worthy causes. Established in 2012 by New York City nonprofit 92nd Street Y, #GivingTuesday is now observed worldwide, with millions of people coming together each year to bring positive change to their communities....

Not a fan of the increasingly shorter winter days? Then you may want to avoid the town of Utqiagvik, Alaska. That's because the northernmost city in the US just experienced its last sunset of the year on November 19, 2019. Even worse, it will not witness a sunrise again until January 23, 2020. More precisely, that means 65 consecutive days, or 1,560 hours, of no daylight....

On November 10, 2019, nine agile mini cheetah robots, built by researchers at the Massachusetts Institute of Technology (MIT), were let off their leash to demonstrate their superior athletic abilities. The four-legged machines, controlled by their human creators, began with a warm-up run across the field in full formation. They then took turns maneuvering a soccer ball. As often happens in games, a couple of the team members got into a skirmish and jostled with each other until they both fell onto their backs. Fortunately, they reconciled for the grand finale — a perfectly synchronized backflip, one that would make even a world-class gymnast like Simone Biles proud!...

Two years ago, aerospace manufacturer SpaceX stunned the world by landing its reusable booster engine — the biggest and most costly part of the rocket used to power spacecrafts into low orbit — on an autonomous drone ship in the Atlantic Ocean. Now, California-based startup Rocket Lab, has come up with an even bolder idea: using parachutes and helicopters to capture the returning booster, or first stage as it is often called, in midair!...
