The blast of Arctic air, which has caused a once-in-a-generation deep freeze across the US Midwest, has paralyzed the region’s cities and towns. Hundreds of schools are closed, thousands of flights and trains have been grounded, and most businesses were forced to shut. Authorities are cautioning residents to stay indoors during this unprecedented chilly weather pattern, which is cold enough to freeze boiling water in midair and can result in frostbite in as little as 5 minutes. The polar vortex’s only silver lining? The beautiful sun dogs being observed at many of the affected areas....

This year’s winter has been particularly harsh on the residents of the central and eastern United States, who have had to endure an abnormally cold weather pattern since the second week of January. Unfortunately, things are going to get even worse starting Tuesday, January 29, 2019. According to the National Weather Service (NWS), the extreme Arctic cold sweeping across the Midwest and Great Lakes will result in dangerously cold wind chills and cause temperatures in some cities to drop to their lowest levels in over two decades....

Most of us have, at some point, experienced travel congestion, especially during major holidays such as Christmas and Thanksgiving. However, nothing compares to the crowds triggered by the Chinese Lunar New Year, or Spring Festival, when millions of people make their way home – usually from cities to rural areas – to celebrate the all-important holiday with friends and family. The spring travel rush, or Chunyun, begins 15 days before the festival – which falls on February 5 this year – and ends 25 days after. The 40-day period collectively results in the world’s largest seasonal human migration. This year will be no exception....

A giant spinning wheel of ice on the surface of the Presumpscot River has enthralled crowds in Westbrook, Maine since Monday, January 14, 2019. Many locals have likened it to crop circles –strange patterns that appear mysteriously overnight in farmers' fields, which have long been theorized to be markers of extraterrestrial communication – and speculated that the icy ring is a landing site for an alien ship. Unfortunately for UFO enthusiasts, experts say that the rare winter phenomenon is a natural occurrence....

Coral reefs are some of the most diverse and vital ecosystems on Earth. The colorful underwater colonies of coral polyps, held together by calcium carbonate, provide homes for many marine plants and animals and help keep the ocean's nitrogen levels balanced. But while scientists are aware of where the world’s reef systems are located, there is no complete record of all the different types of coral that live there. Now, NASA researchers are hoping to entice nature lovers, both experts and amateurs, to help them create a comprehensive database of these all-important ecosystems by playing a fun, interactive video game!...

The eyes of Leonardo da Vinci’s iconic Mona Lisa have long been thought to follow viewers around the gallery of the Louvre Museum in Paris where it is exhibited, as well as those looking at photographs and reproductions of the famous painting. Now, researchers from Germany's Bielefeld University assert that while “The Mona Lisa Effect,” – the impression that the eyes of the subject in a portrait are following the viewer – is real, it is not true for its namesake painting....

Happy 2019! As is the tradition each year, at the stroke of midnight on December 31st, 2018, cities and towns worldwide ushered in the new year with elaborate fireworks displays. Here are a few that we thought were particularly noteworthy....

Though we are treated to several meteor showers throughout the year, most pale in comparision to the grand finale – the Geminids. Expected to be at their peak on Thursday and Friday night (Dec. 13-14, 2018), the dependable meteors rank high in both quantity and quality. Nicknamed the “900-pound gorilla of meteor showers” by NASA, they outweigh other dust streams by factors of between 5 to 500!...

With less than two weeks left until Christmas, cities and towns across the world are aglow with stunning light displays. Though each is special in its own way, some are truly outstanding. Here are a few that made our list of 2018’s most noteworthy....

Dolphins have been known to demonstrate many human-like behavioral traits. These include forming complex relationships to accomplish common goals, teaching one another survival skills, and even “babysitting” each other's kids. Now, some researchers at the Dolphin Plus Marine Mammal Responder in Key Largo, Florida have discovered another thing the intelligent mammals share with humans – a love for television!...

Most dog owners are convinced that their four-legged friends know exactly what they mean when they use certain words like sit, stay, or treat. However, researchers have always wondered whether canines really understand human speech or if they rely on other clues to deduce the meaning. For example, does the word “fetch” conjure up an image of a stick or ball in the dog’s mind, or does the pooch retrieve the object based on cues such as the owner’s tone or gesture? A new study by scientists at Atlanta’s Emory University seems to indicate that “man’s best friend” is not faking it – he/she does indeed know what the owner is saying....

The residents of Ashwaubenon, Wisconsin are no strangers to wild turkeys. However, “Smoke,” a lone bird who has been a fixture in the town since spring this year, is like none other they have encountered before. The renegade turkey pursues moving vehicles, “controls” traffic flow by parking himself in the middle of the road, and even chases after children as they descend from school buses. He is also known to boldly approach residents and gobble at them, as though sharing some pertinent information....

US gymnast Simone Biles, who has dominated the sport since the 2013 World Championships, is often described as “the greatest gymnast of all time” and “superhuman.” The 21-year-old phenom proved herself worthy of both labels at the recently held World Championships in Doha, Qatar when she won a medal in every discipline, including four golds, while battling a painful kidney stone....

The Black Sea MAP (Maritime Archaeological Project) was established to survey the floor of the Black Sea to determine the impact of sea-level changes on early human settlements at the end of the last ice age. The search for answers has led to an unexpected bonus for historians – ancient shipwrecks which provide invaluable information about civilizations of the past. Since the project began three years ago, over 67 old vessels, most from the 14th to 19th centuries, have been found. On October 23, 2018, the team of international sailors and researchers led by University of Southampton Professor Jon Adams announced their most exciting find yet: an intact shipwreck that dates back over 2,400 years!...

While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world’s first kids to be “taught” by a digital teacher. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that pops up on the student’s desktop, tablet, or smartphone screen, when summoned....

With the Halloween festivities over, most people will spend the next few days taking down the spine-chilling decorations and tossing the pumpkin Jack-o’-Lanterns, or scary monsters, that they spent hours creating. While the millions of gourds that end up in landfills every November is alarming, even more so is the massive amount of food waste generated since most people fail to take advantage of the fruit’s edible flesh and seeds....

From creating crazy mnemonics to constructing elaborate mind maps, all of us have at some point experimented with techniques to help us recall relevant information during tests and exams. Now, a group of researchers at the RMIT University in Melbourne, Australia have devised a new trick to help boost our memories – a gap-ridden, and oddly slanted, typeface that they ironically called Sans Forgetica!...

It’s creepy, spooky, and scheduled to rendezvous with Earth shortly after Halloween, on November 11, 2018. Before you get your hopes up, we are not talking about an alien, but asteroid 2015 TB145, a skull-shaped space rock nicknamed ”Death Comet.” This is the second appearance of the eerie-looking asteroid that was first observed by the University of Hawaii's Pan-STARRS-1 (Panoramic Survey Telescope and Rapid Response System) telescope on October 10, 2015....

While the discovery of a new species is always newsworthy, that of a fish spectacular enough to be named Tosanoides Aphrodite, after the Greek goddess of love and beauty, is even more so! Hudson Pinheiro and Luiz Rocha were exploring the deep-sea coral reefs, nearly 400-feet underwater, around Brazil’s Saint Paul’s Rocks archipelago, when they spotted the dazzling pink and yellow fish. The California Academy Of Sciences researchers were so mesmerized by the colorful ocean-dweller that it was only later, when viewing the video footage, that they noticed the 10-foot sixgill shark that had been hovering above....

Natural blue light, which lies in the portion of the electromagnetic spectrum that is visible to the human eye, has several health benefits. These include regulating the body’s circadian rhythm, boosting alertness, and increasing one’s overall feeling of wellbeing. However, the same cannot be said about the stronger artificial blue light, which has permeated our households by way of digital devices such as televisions, smartphones, laptops, and gaming systems. Previous studies have shown that extended exposure causes eye strain, fatigue, headaches, and sleeplessness. Now, new research by Ohio’s University of Toledo (UT) has found that the blue-tinted screens of our addictive gadgets may be accelerating macular degeneration – a condition that results in significant vision loss, eventually leading to blindness....

Yellowstone Park officials were thrilled when the Ear Spring geyser suddenly came to life on September 15, 2018. Visitors fortunate enough to be in the area, watched in awe as the hot pool’s largest eruption since 1957, caused sprays of steaming 200 degree Fahrenheit (93 degree Celsius) water to leap as high as 30 feet (9 meters) in the air. However, the joy turned to shock when employees discovered that in addition to the expected rocks and dirt, the geyser had also ejected human-generated trash....

Every October, farmers across the US harvest millions of pumpkins. Some make it to the dinner table in the form of delicious soups or pies, while others get transformed into scary Halloween monsters. Then there are the select few whose only purpose is to win contests like the Safeway World Championship Pumpkin Weigh-Off held annually in Half Moon Bay, CA – the self-proclaimed “World Pumpkin Capital.”...

Virtual reality (VR)-enhanced roller coasters that keep fans at the edge of their seats are not a new concept. Visitors aboard the Superman: Ride of Steel coaster at Six Flags in Maryland have been immersing themselves in the superhero’s world since 2016, while those aboard Cedar Point, Ohio’s suspended Iron Dragon ride have been dodging ogres and orcs since 2017. But given that water does not bode well for the sensitive electronics, the experience has been harder to offer for water slides. That, however, changed recently with the opening of the Space Glider, the world’s first virtual reality water slide....

Every summer, the beautiful coastal city of Vancouver, Canada hosts a “Car Free Day” Festival. On this day, neighborhoods close their streets to vehicles so artists and local businesses can showcase and sell their wares to the thousands of fairgoers that flock to the event. At this year’s festival on June 17, 2018, visitors seeking something unique and healthy were in for a special treat – unfiltered hot dog water!...
