A new material created by Massachusetts Institute of Technology (MIT) researchers is being hailed as revolutionary. 2DPA-1 is as light as plastic and two times stronger than steel. Unlike currently available polymers, it can conduct electricity and block gas. The scientists believe 2DPA-1 can help lower our carbon footprint and perhaps even reduce the rampant use of disposable plastics....

A holiday associated with a math constant may not seem very exciting. But Pi ("π") Day, observed annually in the US on March 14 (3/14), is an exception. That's because the celebrations may start with math activities centered around pi — the ratio of the circumference of a circle to its diameter, widely recognized as 3.14. But they inevitably end with a slice or two of delicious pie!...

A neatly-laid out sequence of five handprints and five footprints found near the village of Quesang in Tibet is being hailed as the world's oldest human art. The fossilized indentations were etched on travertine — pliable limestone formed by deposits from natural springs that harden over time. Based on the dimensions, the researchers believe the footprints belonged to a seven-year-old, while the handprints were those of a 12-year-old....

February 13, 2022, marked the 25th anniversary of the Great LEGO Spill — the worst toy-related environmental disaster of all time. On this fateful day in 1997, the Tokio Express was battered by a massive, 28-foot rogue wave off the United Kingdom's southwestern coast. The force tilted the cargo ship — en route from Rotterdam to New York — by 60 degrees, causing it to drop 62 containers into the sea. One was filled with about 5 million colorful LEGO bricks!...

The Weddell Sea, an extension of the Southern Ocean off the coast of Antarctica, is known for its abundant wildlife. The 1,242-mile (2,000-km) bay's nutrient-rich waters are home to large populations of seals, penguins, and baleen whales. Now, researchers have uncovered a trove of 60 million icefish nests sprawled across 93 square miles (240 square kilometers) of the seafloor. The nurseries — each guarded by a ghoulish-looking adult — constitute the fish's largest-known breeding colony....

On February 6, 2022, Queen Elizabeth II celebrated her Platinum Jubilee — 70 years to the day she became queen. The 95-year-old is the first British monarch and one of only four documented monarchs, worldwide — Louis XIV of France; Johann II of Liechtenstein, and, most recently, Bhumibol Adulyadej of Thailand — to mark the extraordinary anniversary. The historic milestone will be celebrated with events and initiatives throughout the year, but the main festivities will be held during a four-day holiday weekend in June....

Chimaeras, or ghost sharks, have been around for millions of years. However, the elusive fish, which live at depths of up to 6,000 feet, are largely unknown to science. The lack of crucial information — like how long they live or how often they reproduce — makes it challenging to monitor and protect the 52 known ghost shark species. Now, a rare newborn chimaera, discovered off the coast of New Zealand, may help scientists better understand the mysterious deep-water creatures....

Celebrated annually on February 14, Valentine's Day is one of those rare holidays enjoyed worldwide. After all, what is there not to like about a day when loved ones shower each other with cards, flowers, chocolates, and jewelry? The holiday, which ranks as the fifth highest-spending event in the United States, is also a favorite among retailers....

Want to enjoy the Super Bowl Sunday celebrations, but pass on the NFL game? Then you may want to check out Puppy Bowl XVIII, which will air on Animal Planet and Discovery+ a few hours before the big game. It features adorable puppies competing for the "Lombarky" trophy in a chaotic, but insanely cute, "football" game. The best part is the "players" — selected from animal shelters around the country — all find permanent homes before the game ends....
