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....

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!...

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!...

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!...

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....

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....

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....

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....

There are few celestial events as reliable or as anticipated as the annual Perseid meteor showers. The shooting star show typically begins in mid-July and continues until the end of August. However, it is most visible around mid-August. According to astronomers, this year the best time to watch nature’s fireworks will be the evening of Thursday, Aug 11 and the early hours of Friday, Aug 12....

Always wished we had a second Moon? Then you are in luck! NASA scientists from the Planetary Defense Coordination Office (PDCO) on Mount Haleakala in Maui, Hawaii recently discovered a small asteroid that they believe has been looping Earth for at least a century. But despite its unwavering loyalty to our planet, the researchers have no intention of calling it a moon. Instead, they refer to the asteroid, which has been dubbed 2016 H03, as a “quasi-moon” or “near-earth companion.”...

A contest to crown “The World’s Ugliest Dog” may appear to be derogatory to dogs. However, that is not the intention of the organizers of the Sonoma-Marin Fair where the popular event has been held for the past 28 years. They view the unusual event as a celebration of the spirit and imperfections that make the dogs loveable and adoptable....

The phenomenal success of Finding Dory, the much-awaited sequel to the 2003 film, Finding Nemo, is being met with mixed feelings by marine experts. That’s because though the animated movie is the perfect platform to draw attention to the precarious state of our coral reefs, it may instead result in endangering both the reef and its inhabitants further....

Though “sliced bread” gets the credit, we all know that it is ice cream that deserves the honor of being the world’s best invention. That is probably why on July 9, 1984, former US President Ronald Reagan declared July, National Ice Cream Month, and the third Sunday of the month, National Ice Cream Day. According to Proclamation number 5219, the event should be observed “with appropriate ceremonies and activities.” This, of course. means eating as much of the creamy treat as possible....

To state that China has traffic issues is an understatement. A 2015 study conducted by navigation system maker TomTom revealed that the country is home to five of the top twenty most traffic congested cities in the world. Though Chinese authorities have tried to control the traffic flow with tactics that range from charging road tolls to building expressways with 50 lanes, nothing appears to be working. Now, some engineers are proposing an ingenious solution to ease the country’s traffic woes — An elevated bus that glides over cars!...
