Columbus Day, which is commemorated annually on the second Monday in October, has been a US federal holiday since 1934. However, the celebration, honoring Christopher Columbus's arrival to the Americas, has always been somewhat controversial due to the European settlers' brutal treatment of the Native American people. It has also been argued that the indigenous people had already "discovered" America by the time Columbus landed on the Bahamian island he named San Salvador on October 12, 1492....

Human hair is about 50 times softer than a razor blade, which is made using heat-hardened stainless steel and often reinforced with diamond-like carbon. Yet, a few wisps of hair are powerful enough to dull a blade's sharpness within a few weeks of use. To understand how this impressive feat occurs, a team of researchers from the Massachusetts Institute of Technology (MIT) decided to take a closer look at what happens when the sharp edge of a blade slices through human hair....

A rat may seem like an unlikely candidate to receive a gold medal for bravery and devotion to duty. However, six-year-old African giant pouched rat Magawa, who was honored with British Veterinary Charity PDSA's highest animal award on September 25, 2020, is no ordinary rodent. Over the past five years, the "HeroRAT" has saved hundreds of lives by detecting 39 landmines and 28 unexploded items in Cambodia....

Over the years, the androids have been deployed to perform a large number of human tasks, including building products and providing care and companionship for the elderly. The latest addition to the Japanese "workforce" may be Model-T. This seven-foot-tall robot is currently undergoing trials restocking sandwiches, drinks, and ready meals on shelves at select locations of local convenience store chains Lawson and FamilyMart....

Most people would shudder at the idea of getting caught up in a 73.5-foot wave. But for Brazilian pro-surfer Maya, it presented the perfect opportunity to break her 2018 world record for the largest wave surfed by a female. The athlete skillfully maneuvered the massive swell earlier this year, at the inaugural World Surf League (WSL) Nazaré Tow Surfing Challenge in Praia do Norte, Portugal. It was the same site where she established her first world record by riding an equally-intimidating 68-foot wave....

Experts have long predicted that 3D printing will revolutionize the construction industry by making home builds cheaper, faster, and more environmentally-friendly. However, the uptake has been slower than anticipated because 3D technology to create fully-functional homes has been considered lacking. That perception may change soon with the recent unveiling of the world's first two-story home printed in a single piece in Antwerp, Belgium....

A perfectly-preserved silver dollar, which set a new world record for coin sales when it auctioned for $10,016,875 in 2013, is back on the market, and experts believe it might fetch even more this time! The rare "Flowing Hair" coin, which features a portrait of Lady Liberty on one side and an eagle on the other, will be sold to the highest bidder by Legend Auctions on October 8, 2020, at The Venetian Hotel in Las Vegas....

Andean Condors, which weigh between 20 to 30 pounds (9 to 13 kilograms) and boast a wingspan of more than 10 feet, are one of the world's heaviest and largest flying birds. Yet the majestic vultures, which spend their days circling the Andes mountains and nearby Pacific coasts of western South America in search of carcasses, manage to stay afloat for hours....

Every summer, the Israel Antiquities Authority (IAA) invites teenage volunteers to work alongside archeologists at one of several dig sites across the country. The program, designed to provide the youth with an authentic archeology experience and to help them connect with Israel's history, usually results in the discovery of ancient tools or pottery. However, two teenagers at an excavation site in Yavneh, south of Tel Aviv, struck gold — literally— when they unearthed a clay jar filled with gold coins on August 18, 2020....
