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.

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.

The finding is particularly exciting given that this is the first new predatory plant to be discovered in 20 years....

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.

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.

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 2021 Atlantic hurricane season began with a bang for the residents of Louisiana. On August 29, 2021, the Gulf Coast state was battered by Hurricane Ida, a powerful Category 4 storm that officials believe was the strongest to hit the area in 165 years. To make matters worse, Ida arrived on the sixteenth anniversary of the devastating Hurricane Katrina and made landfall twice....

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....

The social distancing mandates, imposed due to the COVID-19 pandemic, isolated family members from each other in 2020. However, it also resulted in some lifelong friendships between people who would have otherwise never met. In the case of 99-year-old Minnesota resident Mary O'Neill, that person happens to be her two-year-old neighbor, Benjamin Olson....

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.

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....

The historic flights kicked off a new era of space tourism — for anyone who can afford it....
