While Black Friday and Cyber Monday are all about finding the best deals on holiday gifts for yourself and family members, Giving Tuesday serves a more altruistic purpose. Observed annually on the Tuesday after Thanksgiving, it encourages people to help those in need by making financial donations or doing good in their local community. The “Global Day of Giving” was started in 2012 by New York City nonprofit 92nd Street Y and the United Nations Foundation....

The residents of Florida, which is home to over one million alligators, are no strangers to the apex predators. The massive animals are frequently encountered in swimming pools, ditches, and garages. In 2019, Palm Coast resident Donna Heiss even saw a 7-foot gator peeking through her window! However, the giant reptile recently spotted in Naples, Florida, impressed even the most jaded Floridians....

On October 26, 2020, the US Senate voted 52-48 to confirm Judge Amy Coney Barrett as the 115th Associate Justice of the United States Supreme Court. The 48-year-old, who was nominated for the lifetime appointment by President Trump on September 26, 2020, will fill the vacancy left behind by Justice Ruth Bader Ginsburg, who died from complications of pancreatic cancer on September 18, 2020....

When 22-year-old giant panda Mei Xiang gave birth to a healthy cub on August 21, 2020, Smithsonian's National Zoo officials were both excited and anxious. That's because giant panda cubs, which weigh about 100 grams — the equivalent of a stick of butter — when born, are challenging to keep alive. Unable to see, hear, or crawl, the helpless infants are completely reliant on their mothers for food and protection. As it turns out, they had little to worry about. The newborn, who celebrated his eight-week birthday on October 16, 2020, is thriving under Mei Xiang's care and showing signs of becoming a feisty toddler....

Visitors enjoying a quiet breakfast at the Singita Ebony Lodge, a luxury hotel in South Africa's Sabi Sand Game Reserve, were treated to a rare encounter with a leopard in early September 2020. The handful of guests watched in awe —and a little trepidation — as the majestic animal, who appeared to be searching for a tasty morsel, calmly explored the various areas of the restaurant. Fortunately for the humans, nothing on the "menu" seemed to catch the leopard's fancy, and it left as abruptly as it had arrived....

On September 5, 2020, almost 800,000 fans worldwide tuned into American illusionist and endurance artist David Blaine's YouTube channel to witness his first major live event since 2012.

Bei Bei's 2019 departure from the Smithsonian's National Zoo, to join the giant panda breeding program in China's Wolong Nature Reserve, left a big void for fans. What made the loss of the adorable cub even more poignant was the belief that his mother, Mei Xiang, was too old to have more offspring. However, on August 21, 2020, the 22-year-old proved experts wrong by giving birth to a healthy cub....

The San Francisco Zoo's annual "March of the Penguins," to celebrate the graduation of their Magellanic penguin chicks from "fish school," is usually attended by hundreds of cheering fans. Unfortunately, COVID-19 restrictions forced this year's ceremony, held on August 8, 2020, to be limited to a handful of lucky guests and officials. However, the lack of fanfare did not appear to bother the six adorable graduates proudly waddling over to their permanent home on Penguin Island....

Stephen Wamukota, a nine-year-old from Mukwa village in Western Kenya, is making headlines worldwide for his ingenious hand washing machine.

Over the years, there have been numerous attempts to create "glow-in-the-dark" plants. However, none of the approaches — which included infusing plants with nanoparticles of the luciferins and enzymes needed for the phenomenon to occur, or incorporating them with bacterial bioluminescence genes – proved feasible....

Spain's three-month-long lockdown order imposed to curb the spread of the COVID-19 pandemic was finally lifted on June 22, 2020. To celebrate the joyous occasion, the Gran Teatre del Liceu in Barcelona, Spain — one of Europe's oldest and most famous opera houses— staged its first live performance since mid-March. While every seat was occupied, there was not a human to be found. Instead, the sold-out audience comprised 2,292 potted plants carefully selected from local nurseries....

Since early May, visitors to the Padre Island National Seashore off the coast of South Texas have been discovering specimens of the rare blue dragon, or Glaucus atlanticus. Though the name evokes images of flying, fire breathing monsters, the delicate creatures are a type of sea slug that spend their lives in the temperate and tropical waters of the Atlantic, Pacific, and Indian Oceans....

Christie's is well-known for selling expensive, one-of-a-kind items. However, its latest offering is literally "out of this world." On April 30, 2020, the British auction house announced that the fifth-largest chunk of the Moon — a 29-pound (13.5-kilogram) rock dubbed NWA 12691 — was being offered for private sale for a "reasonable' $2.5 million!...

NASA's ambitious plans to land humans on the Moon by 2024 just got one step closer to becoming a reality thanks to the first comprehensive map of our satellite's surface. Unveiled on April 23, 2020, the colorful 1:5,000,000-scale "Unified Geologic Map of the Moon" is the result of decades of painstaking work by scientists from the United States Geological Survey (USGS), NASA, and the Lunar and Planetary Institute....

On March 16, 2020, researchers aboard the Schmidt Ocean Institute's ship Falkor stumbled upon a beautiful *giant* Apolemia, a type of siphonophore, in the Indian Ocean off western Australia. The scientists are not sure of the exact length of the silly string-like creature, which was found in the Ningaloo Canyons at a depth of 2,070 feet (631 meters). However, based on the measurement of its outer ring by a laser-equipped drone, they estimate it was 150 feet (46 meters) long....

On April 7, 2020, the skies will be lit up with a Super "Pink" Moon — the brightest and biggest full moon we will encounter all year! Though Earth's natural satellite promises to be spectacular, that night, those hoping for a pink hue will be disappointed. April's full moon gets its name from pink wildflowers called phlox that bloom in early spring. Though the moniker is misleading, it is undoubtedly better than the alternative nicknames, which include sprouting grass moon, fish moon, and hare moon!...

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....

On Wednesday, February 5, 2020, the US Senate acquitted President Donald Trump of charges that he had abused the powers of his office and obstructed Congress as it investigated his attempts to pressure Ukraine for his political gain.

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.

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....
