Imagine going to the beach and finding thousands of perfectly shaped snowballs scattered around. That is exactly what the lucky residents of Nyda in Siberia’s Yamal Peninsula have encountered since late October....

While ancient scrolls hold many secrets, opening the delicate manuscripts is always a tricky endeavor. The situation becomes even worse when they are charred as was the case with the Ein Gedi scroll discovered by archeologists at the site of an ancient synagogue in Israel in the 1970’s. The animal skin document that resembled a lump of coal was extremely fragile, and therefore, never opened. However, the curators of the Israel Antiques Authority (IAA) preserved it in the hopes that some day, advances in technology would allow them to read what lay inside. Now thanks to a team led by University of Kentucky professor Brian Seales, that has become a reality....

NASA scientists can build rockets, send men to the moon, and may soon even help establish a colony on Mars. But can they carve pumpkins? That was the challenge posed to the brilliant engineers at NASA’s Jet Propulsion Lab in Pasadena, CA six years ago, during Halloween. The friendly competition has since become an annual tradition with teams trying to outdo each other with increasingly hi-tech carvings....

In a reversal of roles, a humpback whale calf was recently seen nudging its stranded mother to safer, deeper waters off the east coast of Australia. The chain of events leading to the heartwarming rescue unfolded near North Stradbroke Island, 62 miles southwest of Brisbane, on Friday, October 7....

On August 27, NASA’s Juno mission completed the first orbital flyby of Jupiter. Traveling at a speed of 130,000 mph, the spacecraft passed about 2,600 miles above the gas giant’s swirling clouds. Though the space probe will be conducting 35 additional flybys before the mission ends on February 2018, this was its closest approach and hence, the most important for data collection. Juno did not disappoint....

If you visit Smithsonian’s National Zoo in Washington DC, you may notice one of the zoo’s resident elephants, Shanthi, strolling around in stylish Teva boots. While the footwear makes the 9,000-pound pachyderm stand out among her peers, its primary purpose is to provide the 41-year-old relief from the side effects of arthritis, a chronic condition that causes painful inflammation and stiffness of joints....

Robots have come a long way since ancient Greek mathematician, Archytas, released a steam-powered wooden dove dubbed “The Pigeon” in 350 B.C. However, the terminator-type rigidity of the machines has hindered them from being useful at tasks like search and rescue operations. While researchers have recently created softer and more flexible robots, they still contain hard electric power and control systems — such as batteries and circuit boards....

What do circles, squares, and triangles have to do with making movies? According to a new video from Now You See It, a YouTube channel that explores film concepts, it is one of the several ways used by directors and cinematographers to influence the audience about a character or a situation....

Looking for some inspiration for your Halloween pumpkin? Then you might want to check out American sculptor and artist, Ray Villafane’s masterpieces. The two-time winner of the Food Network show, “Outrageous Pumpkins,” does not just “carve” pumpkins. He transforms them into 3-D sculptures — ghoulish ones of course!...

Polish explorer Krzysztof Starnawski’s fascination with the Hranická Propast, or Hranice Abyss, an underwater cave in the Czech Republic, began in 1999. The diver, who once held the record for the deepest dive (283-meters) with a closed circuit rebreather, says the cave’s limestone unusual formation led him to suspect that it was a lot deeper than his dives had taken him....

Legendary artist and scientist Leonardo da Vinci, who conducted the first systematic study of friction, has always been credited as the pioneer in Tribology. But while his famous machinery design sketches reflected the inventor’s knowledge of the benefits and drawbacks of friction, precisely when and how Leonardo developed these ideas, has remained a mystery....

The first clue that the 2016 Atlantic hurricane season would be an active one came in January, when Alex, a Category 1 hurricane, arrived six months before the season’s official June 1st start date. Since then, there have been 13 named storms and three hurricanes. However, none have been as devastating as Hurricane Matthew, which has left a trail of destruction all the way from Haiti to North Carolina....

On Wednesday, October 5, Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa won the Nobel Prize in Chemistry for creating machines that are a thousand times thinner than a hair strand! What is even more impressive is that the nanomotors are not made of pistons or gears — just a handful of molecules!...

In August, a team of Mongolian and Japanese researchers unearthed the world’s largest dinosaur footprint in Mongolia’s Gobi Desert. The print that measured 3.6-feet long and 6.4-feet wide, is believed to be that of the titanosaur, a diverse species of sauropod dinosaurs that inhabited Earth during the Cretaceous period, between 70 and 90 million years ago....

Researchers have long attributed the evolution of human intelligence to the size of the brain. It turns out that while a larger skull certainly helped, it was the extra blood sucked in by the brain that transformed humans into one of Earth’s smartest species. The surprising revelation that overturns the previous, long-standing theory comes from a team of scientists at the University of Witwatersrand in South Africa and the University of Adelaide in Australia....

Turkish technology company Letvision recently revealed a working prototype of a real-life transformer that will make all Autobot and Decepticon fans swoon!

It took the team of twelve engineers and four supporting technicians, eight months to build the first prototype, unveiled in late September....

Five years ago, Finland resident Rami Adham embarked on a mission to help the Syrian refugees in his former hometown of Aleppo. The father of six used all his savings to buy food and medicine. As he was leaving for Syria, his three-year-old daughter, Yasmin, offered to donate her toys, in exchange for a new Barbie doll. A deal was made, and the aid worker added 25 teddy bears and 36 Barbie dolls to his already heavy load....

Here is some exciting news for those living in the Western Hemisphere — today, September 30, marks the emergence of the black moon. While that may sound sinister and is even dubbed apocalyptic by some; it is just the moniker given to the second new moon in a month. And like all new moons, this one too will be invisible to the naked eye....

If you think winter luge, where athletes lying on tiny sleds hurtle down slippery icy tracks is dangerous, you probably have never seen the “summer” version of the sport. Street luge is similar to its winter counterpart, except for one thing – competitors do not have the safety of a chute. Instead, they lay on their sleds and zip down paved streets to what seems like certain death!...

Like most bees, the ground nesting Anthophora squammulosa, that are native to parts of North and Central America, are a solitary species. The females lay their eggs in little underground nests and then head out to search for nectar to feed their developing larvae. This process usually takes place in environments with plenty of flora, to ensure a reliable supply of food....
