The fact that ants are fascinating insects has been known for some time. The tiny creatures that make their way around using their built-in GPS, survive floods by morphing into living rafts and are even reputed to predict earthquakes. Now, scientists have discovered a colony of wood ants living in a dark underground barren bunker despite having no apparent source of food....

When the international team of sailors and researchers led by Professor Jon Adams from the University of Southampton established the Black Sea Maritime Archaeology Project, their primary goal was to map the sea floor and study the prehistoric landscapes flooded during the last Ice Age. So you can only imagine their delight, when they stumbled upon an unexpected treasure trove of perfectly preserved shipwrecks, many of which are known from historical sources, but have never been seen before....

On Friday, November 11, Americans will celebrate Veterans Day. The federal holiday honors the brave men and women of the armed forces who risk their lives to protect our freedom. They include members of the US Army, Navy, Marine Corps, National Guard, Air Force, and the Coast Guard....

Researchers had long known that Aboriginal Australians once used boomerangs for hunting and digging. Now, a new study suggests that the natives created ‘killer’ versions of the iconic Australian souvenirs to fight internal battles as well....

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....

Though not mandatory, it has become customary for the US Presidential nominees of the two largest political parties — currently the Democratic and Republican parties — to face off against each other in a series of live debates. While the primary purpose is to convince undecided voters, hearing the candidate’s views on issues ranging from the US economy to foreign policy sometimes sways even staunch party supporters. Given that the nominees get just three chances to present their ideas, the discussions are often contentious. However, the arguments are usually restricted to differences in policies. But this time the rhetoric has been personal. Both Hillary Clinton and Donald Trump spent the first two debates talking more about each other’s character flaws than discussing America’s future. Last night was no different....

Coral reefs are one of the most diverse and important ecosystems on Earth. Not only do they provide food and habitats for the fish and seafood we eat, but they also shelter many other organisms that are crucial for ocean food chains. Experts estimate they contribute about $30 billion USD to the global economy annually, through tourism, fisheries, and coastal protection. Unfortunately, warming ocean waters, acidification, and over-fishing are killing the beautiful reefs at unprecedented levels....

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....

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....

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....

September is usually a month when the atmospheric concentrations of carbon dioxide (CO2) are at their lowest levels in the northern hemisphere. That’s because plants suck up a lot of the gas as they grow during the summer. But this year, the level of the greenhouse gas has remained stubbornly above the symbolic “red line” of 400 parts per million. This has caused scientists to predict that CO2 levels will not return to environment-friendly levels "ever again for the indefinite future.”...

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!...

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....

Earlier this year, a team of engineers led by China’s Song Youzhou suggested that a massive elevated bus that straddled above normal-sized vehicles was the key to easing the world’s traffic woes. Though the concept of the Transit Elevated Bus (TEB) unveiled at the 19th China Beijing International High-Tech Expo on May 22 generated a lot of excitement, most people were skeptical that it would ever become a reality. But they were wrong....

Italian shoe manufacturer Vibram is well known for its minimalist shoe designs. In 2005, the company revolutionized the footwear industry with the introduction of FiveFingers. Designed to replicate being barefoot, the shoes featured thin flexible soles that molded the wearer’s feet. Now, the company has done it again by collaborating with Japanese designer Masaya Hashimoto to create the wrap-around Furoshiki shoes....

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!...

On Wednesday, August 24, the residents of the Apennine regions in central Italy were jolted awake at 3.36 a.m. by a 6.2 magnitude earthquake. To make matters worse, it was followed by over 80 aftershocks, including a 5.5 magnitude tremor that hit Umbria an hour later, at 4.33 a.m....

Scientists have long suspected that the elusive Greenland sharks lived for a long time. It turns out they were right! A new study has revealed that the world’s second largest carnivorous fish may have a lifespan of as long as 400 years. To put it in perspective, that is about twice that of the previously known longest-living vertebrate, the Bowhead whale, which is known to live for up to two centuries....

Do you spend hours studying for a test only to draw a blank when you see the questions? It turns out you are not the only one. For though the human brain may be more powerful than a computer, recalling information is a problem experienced by even the most prepared of students. The lapse in memory can be attributed to various factors, including fatigue, distraction, and nerves....

The Rio 2016 Olympics will be remembered for many things — Katie Ledecky’s dominating performance in the 800-meter freestyle, Simone Biles’s flawless gymnastic routines, Abbey D'Agostino’s and Nikki Hamblin’s sportsmanship during the 5000-meter qualifying run, and the list goes on. However, the moments that will be forever etched on everyone’s minds will be the events that featured two of the world’s greatest athletes — Jamaican sprinter Usain Bolt and American swimmer Michael Phelps — who both declared their retirement following the Rio Games....

While your pet fish may appear to be oblivious of your presence, chances are it knows you extremely well and can probably even identify you from a crowd of humans! At least, that is the conclusion reached by scientists the University of Oxford in the U.K. and the University of Queensland in Australia, following an extensive study of the archerfish, a species of tropical fish that can be found all the way from India, to Indonesia, the Philippines, and Australia....

Remotely Operated Vehicles (ROVs), have been used to conduct undersea tasks, deemed unsafe for humans, for many years. But while they have been very successful at tackling projects like oil rig repairs, the vehicles lack the finesse and dexterity required to handle fragile missions like monitoring coral reefs. Their traditional boxy shape also makes it difficult for the robots to penetrate small areas without damaging the surrounding flora. Now thanks to Stanford University's mermaid robot, OceanOne, these shortcomings may be a thing of the past....
