Drones have come a long way since their first iteration, which was unsteerable and lifted a mere two feet off the ground during its first flight, was unveiled by French inventor brothers Jacques and Louis Bréguet in 1907. Modern-day quadcopters can be programmed to fly autonomously at high altitudes for long distances, swim underwater, and now, thanks to some University of Zurich researchers, even play dodgeball!...

The COVID-19 pandemic has changed life as we knew it just a few weeks ago. Millions of people worldwide are now under mandatory or voluntary lockdowns. All public attractions, including museums and aquariums, are shuttered, and the usually crowded streets of popular tourist destinations are desolate. An unanticipated silver lining during these challenging times for humans is that many of the Earth's other inhabitants are finally getting a chance to leave their normal habitats and roam freely....

For most birds, nest-building entails creating a bowl-shaped receptacle of twigs and dry leaves. However, don't tell that to the common tailorbird (Orthotomus sutorius). The tiny birds, found in urban gardens across tropical ecosystems worldwide, go through extraordinary lengths to sew together a comfortable and safe home for their offspring....

Texas, the biggest of the contiguous US states, prides itself on being larger than life. Everything, from hairstyles to boot heels to food portions to mascots to convenience stores (the largest one boasts 80 soda fountains), is exaggerated. Hence, it should come as no surprise that the Lone Star State is also home to the largest signature on Earth....

Though many single-celled lifeforms have evolved to survive without oxygen, multicellular organisms have always been believed to need it to live. Now, scientists in Tel Aviv, Israel, have found that Henneguya salminicola, a parasite, which spends its life attached to the muscle tissue of fish, has adapted to living without oxygen....

Paleontologists have long determined that modern-day birds evolved from smaller members of the two-legged, meat-eating theropods, such as velociraptors. However, for many years, the only transitional fossil linking the two had been that of the archaeopteryx — a bird-dinosaur hybrid that lived on Earth about 150 million years ago, during the late Jurassic period....

And in the blink of an eye, winter is over — at least when it comes to the clocks. On March 8, 2020, most Americans will "spring forward" by moving their clocks an hour ahead. Though the start of Daylight Saving Time (DST) means sacrificing sixty minutes of precious sleep or playtime on Sunday, it provides for longer spring and summer days....

Though India is home to numerous fun festivals, few are as revered or as widely celebrated as Holi, the festival of colors. Commemorated annually on the last full moon day of the Hindu calendar month Phalguna, this year, the joyous holiday will take place on March 10, 2020....

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....
