With over 4.1 billion people, or around 55 percent of the world's population, living in urban areas, cities and towns worldwide are getting increasingly congested. In addition to spending an excessive number of hours stuck in traffic, residents are also exposed to high air pollution levels caused by transportation emissions. Now, Saudi Arabia hopes to revolutionize urban living with "The Line" — a futuristic city designed around nature, without cars and roads!
After erupting almost continuously for over three decades — from 1983 to 2018 — Hawaii's Kilauea volcano finally seemed to lose steam, producing no lava for nearly two years. The slumber ended on the night of December 20, 2020, when the active volcano began spewing out dramatic lava fountains and giant puffs of gas and steam from a fissure in the northwest wall of the Halemaʻumaʻu crater.
The cameraman zooms in on the anxious elephant, who paces back and forth. However, the pachyderm's demeanor instantly calms down upon hearing a soothing ballad from Disney’s Cinderella, “A Dream is a Wish Your Heart Makes," sung to him by none other than American singer and actress Cher. The now-viral poignant video, published on YouTube on November 30, 2020, was the culmination of the pop singer and animal activist's four-year-long quest to save Kaavan, “The world's loneliest elephant."
Killer 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.
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.
