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....

Imagine being able to visit any foreign country without having to worry about the language barrier. Until recently, universal translating devices only existed in science fiction movies and TV shows. But technology is finally catching up with human imagination, and companies worldwide, are feverishly working to introduce universal translators. Among them is New York-based startup Waverly Labs....

The next time you shriek at the sight of a spider, be aware that the arachnid can hear you loud and clear from as far away as 10-feet! The surprising discovery by Cornell University researchers adds to the already impressive list of arachnid attributes that includes superior vision and ability to weave intricate webs....

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....

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....
