Since landing on Mars on February 18, 2021, NASA's Perseverance rover has achieved numerous "firsts," including beaming audio sounds from the Red Planet's surface. It also made history as the first spacecraft to record sounds from another spacecraft — the Ingenuity helicopter — on another planet....

Geologists have long maintained that our Earth comprises four layers — the crust, the mantle, the outer core, and, the deepest layer, the inner core. However, a team of scientists led by Jo Stephenson, a doctoral student in seismology at Australian National University in Canberra, now asserts that our planet may be harboring a mysterious, fifth layer — an "inner-inner" core as well....

Researchers worldwide are celebrating the discovery of the fossil of an adult oviraptorosaur brooding over a nest of eggs containing unhatched babies. The unprecedented discovery confirms scientists' suspicions that the two-legged bird-like dinosaurs were doting parents, which not only incubated their eggs, but also guarded them —at times putting their own lives at risk....

When Jennifer Johnson and her team embarked on their annual quest to survey the sturgeon population in the Detroit River in mid-April 2021, they had fully expected to find some super-sized specimens. However, the U.S. Fish and Wildlife Service biologists had never anticipated luring in the granddaddy of all sturgeons — a massive, 240-pound, 6-foot, 10-inch long fish that they estimate is at least a century old!...

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....

Regeneration, or the ability to regrow body parts, is a fairly widespread phenomenon in the animal kingdom. However, the skill is usually restricted to growing a new tail or a new limb. Now, researchers have found two species of sacoglossan sea slugs — Elysia atroviridis and Elysia marginata — that deliberately detach their heads from their original bodies and grow brand new ones!...

The beauty of love is that it can happen with the most unexpected person in the most unlikely of places. In the case of a one-year-old stray puppy in Duplin County, North Carolina, that "person" happened to be a bright purple stuffed unicorn at a local Dollar General store. The good news is that this unusual love story has a happy ending!...

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....

When 36-year-old Andy Duran decided to return to his favorite high school hobby — skateboarding — in January 2021, the only obstacle he expected to encounter was his own ability to get back into the sport after the long hiatus. However, the 340-pound skateboarder from Oakland, California, soon realized that was the least of his problems....

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)....

With over 120 pasta sizes and shapes available, one would think there was a design to satisfy every palette. However, Dan Pashman, host of James Beard and Webby Award-winning podcast The Sporkful, was unhappy with the available options. So, the food-lover spent three years, and a substantial amount of his personal savings, to create cascatelli — a new pasta shape that is purportedly more functional than any available today....

The 2020 Summer Olympics torch relay is finally underway. The Olympic flame, which was kindled in Olympia, Greece, on March 12, 2020, and transported to Japan on March 20, 2020, spent a year at the Olympic Museum in Tokyo after the Games were postponed due to the coronavirus. It began its 121-day journey from Fukushima to Tokyo's National Stadium — the venue for the opening and closing ceremonies — on March 25, 2021....

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....

On most days, pulling a harmless prank, or two, on family members would result in a time-out. However, on April 1st, aka April Fools' Day, lighthearted tricks are both expected and welcomed. The origins of the tradition are hazy. Some believe the fun began in 1582 when the world transitioned from the Julian calendar — which ushered in the New Year on the last week of March — to the current Gregorian calendar. Those unaware of the change, or refusing to accept the January 1st start date, were often pranked on December 31st. Others maintain the ritual began as a joyful way to welcome spring....

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....
