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....

Mourning the loss of a loved one was initially thought to be just a human characteristic. However, over the years, experts have observed similar behavior in terrestrial social animals like gorillas and elephants. In one case, a herd of wild elephants spent hours trying to lift the body of their dead matriarch. After accepting her death, the elephants covered the body with leaves and tree branches and kept vigil for two days before finally dispersing. Now, scientists have discovered that even whales undergo tremendous sorrow when they lose an offspring or companion....

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....

The great frigatebird, a species of seabird found across the world’s tropical seas, has a 7 foot wingspan — the largest of any bird species its size. Past research had indicated that these adept pilots could stay aloft as long as a week at a time. It turns out, that the experts and even Christopher Columbus, who noticed the birds on his 1492 voyage to the Americas — and remarked “does not alight on the sea nor depart from land 20 leagues (70 miles)” — had vastly underestimated the magnificent bird’s flying prowess and smarts!...

As predicted, the first debate between US presidential candidates, Hillary Clinton and Donald Trump, that took place at New York’s Hofstra University on September 26, drew a record audience. According to initial estimates, between 70 – 80 million people tuned in to watch the first face-off between the Democratic and Republican presidential nominees. The last time a US presidential debate generated this much interest was in 1980, when incumbent president Jimmy Carter was pitted against former California governor Ronald Reagan....

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....

In 1974, American stuntman Evel Knievel attempted to cross Idaho’s Snake River Canyon aboard a steam-powered rocket. Unfortunately, a parachute deployed prematurely and caused the rocket and its occupant to drift to the canyon’s bottom. While Knievel emerged relatively unscathed from the incident, he never got a chance to attempt the stunt again....

On September 10, 2016, a meteorite weighing more than 30-tons (68,000 pounds) was unearthed in Argentina’s Campo del Cielo (Spanish for “Field of Heaven”) region. The space rock that is amongst the largest intact meteorites discovered thus far, is believed to be part of a massive meteor that disintegrated as it entered Earth's atmosphere approximately 4,000 — 6,000 years ago....

Three-year-old Bailey suffers from Spinal Muscular Atrophy (SMA), a medical condition that affects the spinal cord’s motor nerve cells. As a result, she is unable to sit, stand, crawl, or walk on her own. She also can’t swallow food efficiently or breathe without the help of a machine. But thanks to Surf Dog Ricochet (and some human volunteers), Bailey and a few other kids suffering from SMA recently did what most children their age only dream of — go surfing!...

Monday, August 8, was Earth Overshoot Day. Calculated annually by the environmental advocacy group, Global Footprint Network, it is the day when humanity has consumed all the natural resources — produce, meat, fish, water, and wood — that our planet can regenerate in a single year. This means that for the rest of 2016, we will be using natural resources that are impossible to replace....

When it comes to currency innovation, very few nations can outdo Australia. In 1988, it became the first country in the world to replace paper money with polymer banknotes. Now, the officials have done it again with a five-dollar bill that is not just cool to look at, but also so technologically advanced, that many experts are dubbing it the money of the future!...

Water, or rather the lack of it, is one of the most pressing issues of our times. Unprecedented droughts and growing populations have left many countries struggling to keep up with demand. Given that agriculture is the largest single user of freshwater, providing farmers with new conservation techniques would go a long way in alleviating our water woes. It turns out that a “miracle” powder has been helping drought-stricken Mexican farmers do exactly that for over a decade!...

Any member of the five species of the Prasinohaema (Greek: “green blood”) skinks that that live on the island of New Guinea in the South West Pacific, would have been a shoo-in for J.K. Rowling’s wildly imaginative Harry Potter book series. That’s because besides being the only known land vertebrates to have “vivid lime green” blood, the reptiles also sport green bones, green muscles, and even a green tongue!...

In July 2016, much to the dismay of environmentalists and the Standing Rock Sioux tribe, the US Army Corps of Engineers (USACE) — the federal government body in charge of the nation's waterways — granted the final permits to allow construction of the Dakota Access Pipeline (DAPL). When completed, the 1,172-mile-long, $3.8 billion USD pipeline that snakes through four states will be able to transport up to 500,000 barrels of crude oil from the Bakken Formation area of North Dakota to refineries in Illinois, daily. The builder, Dakota Access, LLC, a subsidiary of Texas-based Energy Transfer Partners, asserts that the underground pipeline is a more direct, cost-effective, safer, and environmentally responsible way to transport crude oil....

Shortly before the school year ended in June, 1,700 American kids got to do what most students can only dream of — play video games in class. No, the 100 educators that allowed this were not slacking off. They were helping Microsoft beta test a new Minecraft Education Edition, which the company plans to offer to schools across the globe within the next few weeks....

At the end of the spring semester in May, students taking Georgia Tech’s online Knowledge-Based Artificial Intelligence course received some stunning news. Jill Watson, one of the nine teaching assistants (TA’s) that had helped them navigate the challenging course for the past five months was not a “she,” but an “it” — an intelligent robot to be precise!...

In 1924, two years after he began excavating Egyptian King Tutankhamun’s (Tut) burial chamber, British archaeologist and Egyptologist Howard Carter finally discovered what he had been seeking: The young pharaoh’s well-preserved sarcophagus. In addition to the scores of precious jewels, amulets, and bracelets that had been buried alongside, Carter also unearthed two daggers wrapped around the boy king’s body. The other also featured a gold handle, but its blade appeared to be made from iron....

Sunday, September 11, 2016, marks the 15th anniversary of the most daring and deadliest terrorist attack on American soil. Planned and executed by Islamic extremist organization Al Qaeda, the unprovoked act of violence is what led to our ongoing "Global War On Terrorism” and changed life as we knew it, forever....

It may appear strange to hear that crops are making headlines. But this is no ordinary produce — these fruits and vegetables have been grown in simulated Martian and lunar soil! While that in itself makes them special, what makes this batch even more so is that it is safe for human consumption!...

In 1979, the Voyager 1 spacecraft discovered that Alaska, Canada, Siberia, and Antarctica were not the only places with spectacular auroras or “polar lights” — Jupiter, the largest planet in our solar system, has them as well. While the lights have been studied intensely since, a recent month-long observation of Jupiter’s north pole by the Hubble Space Telescope has resulted in some beautiful, never before seen images of the planet’s northern lights....
