The second Monday in October has traditionally been known as Columbus Day in honor of the Italian explorer's "discovery" of the Americas on October 12, 1492. However, the US federal holiday, which will be celebrated on October 11 this year, has always been controversial due to the European settlers' cruel treatment of the Native American people....

Many superheroes wear capes. But Batman's imposing floor-length cloak is legendary. The twisting sheath not only adds to the Dark Knight's mystique but also transforms into a rigid fabric that allows him to fly for extended periods. Now, engineers at the California Institute of Technology (Caltech) and Nanyang Technological University (NTU) in Singapore have replicated the shape-shifting material in real life....

La Palma, one of Spain's Canary Islands, has been feeling the wrath of the Cumbre Vieja volcano since September 19, 2021. The explosive volcano, which came to life shortly after 3:00 pm local time, has been spewing out large amounts of molten lava, sometimes up to 20 feet (6 meters) high. The slow-moving rivers of magma have destroyed nearly 400 homes, buried dozens of kilometers of roads, and consumed hundreds of acres of farmland....

Humans have flown to the Moon and may even make it to Mars. But providing clean water to all remains a challenge. The World Health Organization estimates that one in three people globally still do not have easy access to clean water. While desalinating ocean water is an obvious solution, the current process is both expensive and harmful for the environment. Now, some Malaysian students may have found a cheaper, more sustainable way to transform seawater into drinkable water....

The school day had just ended at Isaac Dickson Elementary School in Asheville, North Carolina. Most students had left, and the ones in the school's "supervised homework help" program were inside the campus. Fifth-grade teacher Betsie Stockslager Emry was also heading home when she noticed two playful black bears entering the empty playground. What happened next will bring a smile to your face....

One of the world's most iconic landmarks just got transformed into a work of art. From September 18 to October 3, 2021, the Arc de Triomphe in Paris, France, will be embellished with 25,000 square meters of shimmering silvery-blue plastic fabric, held in place by 9,842 feet (3,000 meters) of red rope. The installation, dubbed "L'Arc de Triomphe, Wrapped," is the brainchild of the late artist duo Christo and Jeanne-Claude....

Hawthorne, California-based SpaceX is known for making history. It was the first private spaceflight company to transport astronauts to the International Space Station and the first to develop a reusable rocket booster. On September 18, 2021, the American aerospace company did it again by completing the world's first-ever all-civilian mission to space....

The Sequoia National Park in California's southern Sierra Nevada mountains is best known for its namesake giant sequoias. The park boasts 40 groves of the massive trees, which occur naturally only on its western slopes. But the most beloved is the Giant Forest, a collection of 2000 trees that includes half of the Earth's largest and longest-living trees. This past weekend, the ancient wonders came dangerously close to being scorched by the KNP Complex Fire. But thanks to quick-thinking firefighters, the precious grove has been saved....

After years of intense public pushback, the now-shuttered Ringling Bros. and Barnum & Bailey Circus finally announced the retirement of their Asian elephant performers in 2016. While the decision was a resounding victory for animal lovers and activists, it raised a new issue. The mighty pachyderms were raised in captivity and lacked the skills to survive in the wild. Now, thanks to Florida-based White Oak Conservation, the animals have a new home — one where they can roam freely....

The western false asphodel — an herb-like plant found in abundance along North America's West Coast — has been known to science since 1879. But it is only recently that researchers from the University of British Columbia discovered the innocent-looking plant's penchant for insects. The finding is particularly exciting given that this is the first new predatory plant to be discovered in 20 years....

National Hispanic Heritage Month is observed annually in the US from September 15th to October 15th. The event honors the histories, cultures, and contributions of American Latinx and Hispanic communities. This includes all residents from — or descendants of someone from — Spain, Mexico, the Caribbean, and Central and South America. The commemoration began in 1968 as Hispanic Heritage Week. It was expanded to a month by President Ronald Reagan in 1988....

The 2021 US Open Women's Singles final between 18-year-old Emma Raducanu and 19-year-old Leylah Fernandez was one of the most anticipated Grand Slam tournaments in recent history. It was the first all-teenage final since the 1999 US Open and the first major final — men or women — since 1968 to feature two unranked players....

The Henan Province in central China is a treasure trove of dinosaur eggs. However, the odd-looking black orb with a blue tint, presented to Fenglu Han and Haishui Jiang by a farmer in 2018, was unlike any dinosaur egg the experts had encountered before. The paleontologists from the China University of Geosciences initially thought the egg might belong to a new species of the prehistoric giants....

The pandemic-delayed Tokyo 2020 Paralympic Games, which took place from Aug. 24 to Sept. 5, 2021, attracted a record number of competitors. A total of 4,403 athletes — 2,550 male and 1,853 female — competed across 22 sports and 23 disciplines. Here are a handful of the incredible men and women whose determination and grit shattered stereotypes and exhibited the amazing opportunities that can come from following your dreams....

The longest war in American history has ended. On August 31, 2021, a US aircraft carrying the remaining US officials in Afghanistan lifted off from Kabul, ending the nation's almost 20-year presence in the country. The chain of events leading to the long, drawn-out war began early on September 11, 2001....

Mattel's Barbie Role Models series, designed to inspire young girls to pursue their dreams, has highlighted the work of many incredible women. On August 4, 2021, the US toymaker revealed the latest additions to the collection — custom, one-of-a-kind dolls modeled after six female COVID-19 frontline workers....

Wildlife filmmaker Kim Wolhuter was just hoping for some authentic footage of an elephant herd climbing a steep path out of the Majale riverbed in the Mashatu Game Reserve in Botswana. Instead, she was able to capture a heartwarming video of a stranded baby elephant being helped up a cliff by the herd's matriarch....

Rosh Hashanah, or Jewish New Year, will be celebrated from sundown on September 6, 2021, through sundown on September 8, 2021. The two-day observance, which starts on the first day of Tishrei — the seventh month on the Jewish calendar — commemorates the creation of the world....

Even those that do not particularly care for math will agree that pi, or “π," is fascinating. The numerical constant — defined as the ratio of the circumference of a circle to its diameter— is recognized by most as 3.14. However, Pi is an irrational number. This means it can't be written as a fraction. Instead, it is infinitely long and never forms a repeating pattern. While individuals attempt to break records by memorizing pi's decimal points, scientists strive to find its most accurate value using new algorithms and powerful computers....

Clothing made from synthetic materials, such as polyester and nylon, has many positive attributes. It is cheap to produce, lasts for a long time, and is comfortable to wear. However, the fabric, made from petroleum, has one major downside. The tiny polymer strands — or what we call lint — that shed from the textiles during each laundry cycle are big contributors to plastic pollution. Now, some scientists from Lithuania have found a way to recycle the textile waste into clean energy....

On August 8, 2021, the United Nations' Intergovernmental Panel on Climate Change (IPCC) released its first assessment of climate science since 2013. The news was not good. The report stated that this past decade was the hottest in 125,000 years and that the atmospheric carbon levels are the highest in at least 2 million years. Glaciers are melting faster than any time in over 2,000 years, and ocean levels are rising at twice the rate since 2006....

The COVID-delayed 2020 Tokyo Olympics ended on August 8, 2021, with a spectacular closing ceremony and a fireworks show. To mark the occasion, the seven astronauts aboard the International Space Station (ISS) organized the first-ever space Olympics. The four events, modeled after classic Summer Games competitions, included fun twists to account for weightlessness....

Snipping off the sides of an acclaimed painting to fit an assigned space would be unheard of in modern times. But that is exactly what was done to one of Rembrandt van Rijn's most famous works, The Night Watch, almost 300 years ago. Now, Amsterdam's Rijksmuseum has finally managed to restore the painting to its original glory with the help of artificial intelligence (AI)....

For most people, Friday the 13th is just another day on the calendar. However, for the superstitious, it is the unluckiest day of the year. The irrational fear of Friday the 13th is called friggatriskaidekaphobia. It affects over twenty million people in the US and many more worldwide. Some of the anxiety can be blamed on the namesake movie series. However, the day's bad reputation began long before the film's hockey-masked villain, Jason Voorhees, made his debut in 1980....
