Every year, on the second Sunday of May, Americans show their appreciation for the real-life heroes in their lives — moms — with special treats and lavish gifts. This Mother's Day will be no exception. A National Retail Federation (NRF) survey of 7,818 people revealed that the approximately 83 percent of US adults who plan to celebrate the holiday on May 9, 2021, will each spend an average of $220.48. The total, an astounding $28.1 billion, is the highest amount in the survey's 18-year history and easily topples 2020's record spend of $26.7 billion....

British sculptor Jason deCaires Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has submerged over 850 massive artworks in numerous site-specific "sculpture parks" worldwide. On February 1, 2021, Taylor unveiled his latest endeavor — The Underwater Museum of Cannes....

When famed archeologist and former minister of antiquities, Zahi Hawass, and his team set out to excavate an area near the Egyptian city of Luxor in September 2020, all they were hoping to find was King Tutankhamun's mortuary temple. Instead, the archeologists stumbled upon the largest ancient city ever found in Egypt. Hawass, who revealed the discovery on April 8, 2021, believes the enormous, well-preserved metropolis is the “So’oud Atun,” or the "Rise of Aten," whose location has eluded scientists for decades....

NASA made history on April 19, 2021, by conducting the first controlled flight of an aircraft on another planet. In what is being described as a "Wright brothers moment," the tissue-box-sized Ingenuity gradually ascended to an altitude of 9.8 feet (3 meters) above the surface of Mars and hovered for 30 seconds before gracefully descending to land on its four legs....

Every April 22, over a billion people around the world celebrate Earth Day by participating in neighborhood clean-up activities and environmental teach-ins. The planet's largest civic event began in 1970 when twenty million Americans poured out onto the streets to urge lawmakers to take action to protect the environment before it was too late. Now boasting over 50,000 partners in 195 countries, the Earth Day Network (EDN) has led to the establishment of numerous environmental policies, including the Clean Air Act, the Clean Water Act, and the Endangered Species Act....

On Saturday, April 17, 2021, Queen Elizabeth II bade her final farewell to Prince Philip— her husband of over 70 years. The solemn 50-minute service was limited to just 30 senior royals due to the COVID-19 pandemic. The Duke of Edinburgh was laid to rest inside the Royal Vault at St. George’s Chapel alongside the remains of 24 other royals, including three kings of England....

Fifteen US states, including New York, Illinois, Georgia, Virginia, Maryland, New Jersey, as well as Washington D.C., will soon be buzzing with billions, and perhaps even trillions, of cicadas. The noisy, red-eyed members of Brood X, which have been hibernating underground for the past 17 years, will emerge unannounced as soon as the conditions are right: the soil is 64 degrees, and on a night that's humid enough but free of wind and rain....

For the more than a billion Muslims worldwide, there is nothing more sacred than the month of Ramadan, or Ramazan. It was during this ninth month of the Islamic lunar calendar that Jibril (the Archangel Gabriel in the Judeo-Christian faith) revealed the first verses of the Quran — Islam's holy text — to the prophet Muhammad. The auspicious month's start, based on the appearance of the super-slim young crescent Moon, is determined by moon-sighting committees in various Muslim countries, most notably in Saudi Arabia. This year, Ramadan will begin on Monday, April 12th, or Tuesday, April 13th....

While bioluminescence — the ability to glow in the dark — is a fairly common occurrence in fish and squid that live in the ocean's darkest depths, its presence in sharks is not as well-documented or understood. Now, the discovery of the largest-known luminous vertebrate — the six-foot-long kitefin shark — and two other glowing shark species has enabled researchers to gain valuable insights into the luminescent abilities of the deep-sea creatures....

When Christie's set out to auction its first-ever digital-only artwork — "Everydays: The First 5000 Days"— on March 1, 2021, they had fully expected it to fetch more than the minimum bid of $100. However, the 255-year-old British auction house had never in its wildest dreams envisioned that the unique masterpiece, minted by Mike Winkelmann, aka Beeple, would fetch a record $60.25 million ($69.3 million with fees)....

Easter, which will be observed on April 4, 2021, is the oldest and most important Christian festival. Many adults commemorate the holiday, which celebrates the resurrection of Jesus Christ on the third day after his Crucifixion, with prayers and fasting for 40 days before the event. For children in the US, Easter is largely about fun activities like seeking out candy-filled eggs, meeting the Easter bunny, and participating in spring parades. However, not everyone celebrates this all-important holiday with these traditions....

A 200,000 metric ton cargo boat blocking the Suez Canal for six days has finally been freed, clearing the way for over 300 ships waiting to cross one of the world's busiest waterways. The Japanese-owned Ever Given has been wedged sideways into the sandy banks of the 120-mile-long (193-kilometer-long) and 78-feet-deep (24 meter-deep) channel since March 23, 2021. It was dislodged on March 29, 2021, by a fleet of tugboats that worked all night to take advantage of the king tides — high tides that occur during a full moon when the Sun, Earth and the Moon are aligned....

The idiom “shoot for the stars” has just taken on a literal meaning for cancer survivor Hayley Arceneaux. On February 22, 2021, the Memphis, Tennessee, native was selected to be one of four crew members of the SpaceX Inspiration4 — the world's first civilian astronaut mission. The 29-year-old will make further history as the youngest American — and the first with a prosthetic limb — to travel to space....

India is home to a wide variety of festivals, each of which is celebrated with much gusto. However, few are as exciting or as anticipated as Holi, the spring festival of colors. The fun holiday, observed annually on the last full moon day of Phalguna — the 12th and final month of the Hindu year — falls on March 29th this year....

A well-known Chinese proverb states: "A journey of a thousand miles begins with a single step." On March 27, 2021, millions of people worldwide will take the first step towards reversing climate change by turning off all lights and electronics from 8:30 - 9:30 PM local time. The hour-long voluntary rolling blackouts, also observed by landmark structures such as the Eiffel Tower and the Empire State Building, are more than symbolic gestures. They are catalysts for urgent change....

Though it is not unusual to find marine animals thriving under the Antarctica seafloor, researchers had always assumed that all life would become less abundant farther away from open water and sunlight. However, the discovery of filter-feeding organisms — 160 miles (260 km) away from the open ocean, with temperatures of −2.2°C and under complete darkness — suggests that life in the world's harshest environment may be more adaptable and diverse than previously thought....

Mount Etna, Europe's most active volcano, has been erupting regularly since 2011. However, the latest series of explosions, which began on February 16, 2021, has been particularly noteworthy. Emanating from the youngest of the volcano's four craters — the Southeast Crater— they have spewed spectacular fountains of lava as high as 0.9 miles (1.5 kilometers). To put it in perspective, that is about three times the height of One World Trade Center, the tallest building in the United States....

St. Patrick may have been an Irish clergyman, but his death anniversary — observed annually on March 17 — is celebrated worldwide, even in cities and towns with few or no ethnic Irish people. Here is a brief history of the man behind the holiday and the origins of some of the fun traditions associated with the commemoration....

A team of Swedish scientists has successfully extracted and reconstructed the world's oldest DNA from the tooth of a Siberian mammoth, which roamed Earth over a million years ago. Also known as deoxyribonucleic acid, the all-important molecule — which contains the genetic instructions for the development and function of living things. — provides new insights into the evolution of the ancient Ice Age giants. Prior to this, the oldest DNA sequenced came from the bone of a horse that trotted around Canada about 700,000 years ago....

King penguins, the second-largest penguin species, typically sport a distinct black-and-white coat with a yellowish-gold dash of color on their collar. However, one young penguin in the South Atlantic appears to have missed the memo on the dress code. It decided to forgo the black feathers and retain just the bright yellow plumage....

On March 14, 2021, millions of Americans and Canadians will mark the start of Daylight Saving Time (DST) by moving their clocks forward an hour. The time manipulation — which will result in the loss of sixty minutes of precious sleep or leisure time on Sunday — is designed to enable North Americans to enjoy longer days during the upcoming spring and summer months....

In 2011, conservationists moved eight Rothschild's giraffes to Longicharo Island, a rocky peninsula on Lake Baringo in Western Kenya. The scientists hoped the isolated area would save the endangered animals from poachers and allow their numbers to multiply. However, intense rainfall in August 2020 caused the lake water levels to rise substantially, cutting the area off from the mainland and reducing the once lush, 100-acre habitat to about eight acres....

The 1984 discovery of the Whydah Galley — the only fully verified and authenticated pirate shipwreck of the Golden Age of Piracy (1650-1720) ever found — has yielded an enormous treasure trove of artifacts. However, any evidence of its legendary captain Samuel, or "Black Sam," Bellamy has proved elusive. That may change soon thanks to the recent discovery of six skeletons found embedded in the ancient wreck's compacted masses of matter....

The NASA Perseverance rover's 293 million mile (472 million km) journey to Mars ended successfully on February 18, 2021, with a picture-perfect landing inside the Jezero Crater. The car-sized, six-wheeled rover, nicknamed Percy, is the US space agency's biggest and most advanced explorer to date. Its primary mission is to search for signs of ancient microbial life on Mars....
