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....

Faced with a declining population and shrinking workforce, Japan has been increasingly turning to robots for help. 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....

Researchers have long been aware of the presence of rust, or hematite, on Mars caused by the chemical reaction between the iron ore on the planet's surface and water and oxygen from the ancient past. However, they had never expected to find the reddish-brown iron oxide on the Moon, given that our satellite is missing two of the three key components — moisture and oxygen. Now, a new study, based on recent data from India's Chandrayaan-1 Moon-orbiting spacecraft, suggests that the Moon is displaying signs of rust and it may be Earth's fault....

Supreme Court Justice and feminist icon Ruth Bader Ginsburg died at her home in Washington, DC, on September 18, 2020, from complications of metastatic pancreatic cancer. The 87-year-old, who was appointed to the nation's highest court by President Bill Clinton in 1993, was the longest sitting Supreme Court Justice. She was also only the second woman, after Justice Sandra Day O'Connor, to serve in this position....

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....

Visitors enjoying a quiet breakfast at the Singita Ebony Lodge, a luxury hotel in South Africa's Sabi Sand Game Reserve, were treated to a rare encounter with a leopard in early September 2020. The handful of guests watched in awe —and a little trepidation — as the majestic animal, who appeared to be searching for a tasty morsel, calmly explored the various areas of the restaurant. Fortunately for the humans, nothing on the "menu" seemed to catch the leopard's fancy, and it left as abruptly as it had arrived....

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....

On September 5, 2020, almost 800,000 fans worldwide tuned into American illusionist and endurance artist David Blaine's YouTube channel to witness his first major live event since 2012. Called Ascension, the stunt involved Blaine strapping himself to 52 colorful helium balloons and soaring into the clear blue skies above Arizona's Great Basin Desert....

September 11, 2020, marks the 19th anniversary of the most brazen and deadly terrorist attacks on American soil. The unprovoked act of violence, planned by Islamic extremist organization Al Qaeda, killed 2,977 innocent people and changed life as we knew it forever....

When the United States formally entered World War II — the six-year-long global conflict that began in 1939 with Nazi Germany's attack on Poland — in 1941, millions of brave Americans helped to fight for the cause. Among them was New Orleans resident Lawrence Brooks, who served the country for five years as a soldier in the US Army's 91st Engineer Battalion. Fortunately for us, Brooks, who will celebrate his 111th birthday on September 12, 2020, is still around to share his exciting encounters....

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....

Invented by French teenager Louis Braille in 1824, braille has enabled millions of visually impaired kids worldwide to learn to read and write. However, the system of raised dots, representing individual alphabet and numbers, can be complicated for younger students to grasp. As a result, parents and educators are increasingly shunning the tactile literacy system, which is taught using special textbooks, in favor of online learning programs. Now, Denmark's LEGO Group hopes to reverse the trend with the help of braille bricks that allow children to learn through play....

Marvel fans and movie enthusiasts worldwide are mourning the sudden death of Hollywood star Chadwick Boseman. The 43-year-old actor, best known for his portrayal of T'Challa — the king and protector of the fictional African nation of Wakanda in Black Panther — passed away on August 28, 2020, after a four year battle with colon cancer. The news came as a shock to most people since the intensely private Boseman, who was diagnosed at stage 3 cancer in 2016 — the year King T'Challa debuted in Captain America: Civil War — never spoke publicly about his illness....

Scientists from the University of Texas at Austin have finally solved the mystery of a massive fossil that has been sitting unlabeled and unidentified at a Chilean museum for almost a decade. The relic, which resembles a deflated football, is the largest-known soft-shelled egg from a marine reptile that inhabited Earth over 66 million years ago — about the time of the mass animal extinction event. Measuring more than 11 by 7 inches it is also the second-largest egg belonging to any known animal, behind only the now-extinct elephant bird....

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....

Bei Bei's 2019 departure from the Smithsonian's National Zoo, to join the giant panda breeding program in China's Wolong Nature Reserve, left a big void for fans. What made the loss of the adorable cub even more poignant was the belief that his mother, Mei Xiang, was too old to have more offspring. However, on August 21, 2020, the 22-year-old proved experts wrong by giving birth to a healthy cub....

To the novice baker, the classic teardrop-shaped baking chip, created by Nestle in 1941, may appear like the perfect mechanism to introduce specks of chocolate to cookies and other treats. However, experts assert that the chip's dense bottom, which blocks the oven heat to retain some shape, prevents the consumer from fully experiencing the luxurious feel and taste of the melted chocolate. Now, Tesla engineer Remy Labesque has rectified the decades-old design flaw with a stylish, pyramid-shaped version that purportedly melts in your mouth, instead of sticking to the teeth like traditional chocolate chips....

North America's relatively calm summer weather ended last week when a powerful derecho swept across the Midwest — from South Dakota to Ohio — on August 10, 2020, and a rare firenado struck Northern California on August 15, 2020. If you are like most people, you have probably never heard of either of the rare natural phenomena. Here is a brief explanation of the incredible extreme weather events....

While astronomers have discovered evidence of thousands of exoplanets, obtaining direct images of the distant worlds has always been a challenge. That's because the planets tend to huddle close to the star they orbit and often get concealed by their star's dazzling light. Of the handful of images captured, most are of a single planet orbiting a Sun-like star. The only two multi-planet systems photographed feature brown dwarfs, or "failed stars," which are radically different in nature from the Sun. Now, an international team of scientists may have finally captured a young, Sun-like star with two giant Jupiter and Saturn-like planets in orbit....

The San Francisco Zoo's annual "March of the Penguins," to celebrate the graduation of their Magellanic penguin chicks from "fish school," is usually attended by hundreds of cheering fans. Unfortunately, COVID-19 restrictions forced this year's ceremony, held on August 8, 2020, to be limited to a handful of lucky guests and officials. However, the lack of fanfare did not appear to bother the six adorable graduates proudly waddling over to their permanent home on Penguin Island....

On August 11, 2020, presumptive Democratic presidential nominee Joe Biden made history by announcing California Senator Kamala Harris as his running mate for the upcoming election. Harris, who is the daughter of immigrants from Jamaica and India, is the first African American woman on a major party ticket and only the fourth woman in US history to run for vice president. She is also the first person of Asian descent to appear on a presidential ticket....

Over the years, researchers have made numerous attempts to make Harry Potter's invisibility cloak a reality. While each version has been slightly better, none have come close to the one donned by the young wizard. Now, scientists may be able to get some tips from an unlikely source — ultra-black deep-sea fish that have evolved the capability to hide in plain sight to avoid detection....
