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.
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.
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.
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.
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.
Scattered across the ocean bed, and often hidden from the human eye, are hundreds, or perhaps even thousands, of "blue holes." The massive underwater sinkholes, which host a diverse biological community — ranging from coral to sponges to sharks to sea turtles — were formed thousands of years ago when groundwater dissolved karst, a type of porous limestone rock found on ocean floors.
Over the years, there have been numerous attempts to create "glow-in-the-dark" plants. However, none of the approaches — which included infusing plants with nanoparticles of the luciferins and enzymes needed for the phenomenon to occur, or incorporating them with bacterial bioluminescence genes – proved feasible.
