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....

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....

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....
