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....

Ryker, a gorgeous Belgian Malinois, achieved instant Internet fame in December 2018 after the trainers at the Double H Canine Training Academy in Louisville, Kentucky, released a hilarious training test video of the adorable puppy. Captioned "Epic Service Dog Training Failure," it showed the enthusiastic dog trying his best to follow the instructions, but miserably failing at every trick, that he was taught....

California's Yosemite National Park is home to numerous stunning waterfalls. However, from mid-to-late February each year, the unlikely star of the pristine preserve is Horsetail Fall — a small, nondescript waterfall that forms over the eastern edge of the park's famous vertical rock formation, El Capitan, every winter. That's because, during the two-week-period, the temporary 1,000-foot fall frequently transforms into a spectacular "firefall" for about ten minutes a day during sunset....

While jewelry crafted from gold can be gorgeous, even ardent fans will admit that wearing the heavy metal over long periods of time can get a little cumbersome and annoying. Now, researchers from Swiss university ETH Zurich have created a new form of lightweight gold that weighs five to ten times less than traditional 18-carat gold — which typically comprises 75 percent gold and 25 percent copper — but retains the same purity....

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....

An elephant, who accidentally fell into a dry, 25-foot deep well in Northeast India, lived to see another day thanks to the quick-thinking rescuers' scientific knowledge. The chain of events unfolded early in the morning on Tuesday, January 28, 2020, when residents of Amliya toli village, in the state of Jharkhand, awoke to the cries of the stranded pachyderm and called the forest department for help....

Shana Stamey and her family had no doubt that their gorgeous white German Shepherd, Gypsy, would give birth to some adorable puppies. However, the Clyde, North Carolina, residents would have never guessed that one of the eight canines born on January 10, 2020, would emerge into the world with a stunning lime-green coat!...

Swiss military-trained pilot and aviation enthusiast Yves Rossy is famous for pulling off seemingly impossible stunts. Over the years, the adventurer has used his jet-propelled carbon wings to soar across the Grand Canyon, circle over Japan's Mt. Fuji, and even fly alongside the world's largest commercial airplane, the Airbus A380. However, the one thing that has eluded the "Jetman" is the ability to take off from the ground. All his "flights" begin after being transported to a certain altitude aboard a helicopter or plane....

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....

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....

While dogs openly demonstrate joy or displeasure through grins and grimaces, discerning a cat's emotions from its face is often hard, even for its owners. Now, researchers from Canada's University of Guelph assert that stoic as they may appear, cats also express emotions on their faces — one just has to learn how to interpret them!...

Every holiday season, Canada's WestJet airlines finds a unique way to bring Christmas cheer to hundreds of unsuspecting families. Past "miracles" have included surprising weary travelers with iPods, fulfilling extravagant Christmas wishes from passengers aboard two late-night flights, and reuniting loved ones living in different countries for the holidays. In 2019, the company decided to let customers determine if they wanted to keep the generous gift being offered to them or donate it to a family in need....

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....

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....

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!...

On Monday, November 11, 2019, stargazers will be treated to an unusual sight: our solar system's smallest planet, Mercury, passing between the Earth and the Sun. The rare event, called a transit, will be the fourth of just 14 transits of Mercury that will occur during the 21st century. The last one took place on May 8, 2016, and the next will not occur until November 13, 2032. However, it will not be visible from North America, which means the continent's residents will have to wait until May 7, 2049, to observe the celestial delight again....
