Suspended liquids and inverted floating boats may seem like something straight out of a Harry Potter novel. However, as a team of scientists at the ESPCI in Paris, France, recently demonstrated, the gravity-defying feats do not require magical spells — just the knowledge of some basic laws of physics!...
Read news articleIt's been only a week since October began, and skywatchers have already been treated to a gorgeous, full Harvest Moon and the opportunity to observe Mars at its brightest since 2003. As it turns out, the two events were only a precursor to the other thrilling celestial treats in store for us for the rest of the month. They include two meteor showers, a rare chance to see the Red Planet in opposition, and a "Blue Moon."...
Read news articleThough it has been retired since 2018, the observations made by NASA's Kepler Space Telescope during its decade-long mission continue to allow researchers to identify new worlds in our galaxy. The latest to make headlines is an Earth-sized exoplanet that rotates around its dwarf star in just 3.14 days. The similarity to the close approximation of the mathematical constant pi — the ratio between a circle's circumference and its diameter — has earned the alien world the nickname "Pi planet."...
Read news articleKiller whales, or orcas, are the largest members of the oceanic dolphin family. While the intelligent mammals, which hunt in large pods, are known for their orchestrated attacks on unsuspecting marine animals, they have never posed a threat to humans. However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal. The unusual hostility is puzzling scientists worldwide....
Read news articleHuman 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....
Read news articleFaced 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....
Read news articleResearchers 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....
Read news articleVisitors 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....
Read news articleAndean 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....
