Blue Light Emitted From Digital Devices May Accelerate Blindness

By on

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.

Japan Makes History By Landing Robots On An Asteroid

By on

The Japanese Aerospace Exploration Agency, or JAXA, made history on September 21, 2018, when its unmanned probe Hayabusa2 successfully landed two moving robots, collectively called MINERVA-II1, on asteroid Ryugu’s surface. A few weeks later, on October 2, the spacecraft repeated the feat by deploying a third, slightly bigger, rover called the Mobile Asteroid Surface Scout (MASCOT). The information collected from the primitive asteroid could help shed light on the origins of our solar system and how the first life forms arose on Earth.

British Artist Banksy's Painting Self-Destructs Minutes After Being Auctioned For $1.4 Million

By on

The sale of a Banksy painting for $1.4 million, the highest-ever paid for the British street artist’s solo work, was the perfect finale for Sotheby’s “Frieze Week” evening contemporary art auction on October 5, 2018. But before the auctioneers had time to celebrate, an alarm sounded and then, to everyone’s dismay, the artwork began to self-shred while sliding down the frame.

Perfectly Preserved Ice Age Animals Still Have Skin, Muscle, and Hair

By on

The Klondike region in Canada’s Yukon territory, which is famous for its gold mines, was once home to a large variety of animals. They included the long-extinct saber-toothed cats and woolly mammoths, as well as creatures like gray wolves, whose descendants still roam the Arctic territories. Hence, it is not uncommon for miners to stumble upon fossilized remains of the Ice Age inhabitants while unearthing the precious metal. However, the mummified remains of a caribou calf and wolf pup, unveiled in Dawson City, Yukon on September 13, 2018, are among the oldest-known specimens found with perfectly preserved skin, muscle, and hair. The wolf pup is also the only one of its kind discovered to date.

World's First Virtual Reality Water Slide Opens In Germany

By on

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.

K-pop Sensation BTS Urges The World's Youth To "Find Your Voice"

By on

A few years ago, the idea that a Korean pop, or K-pop, group would perform to sold-out shows worldwide, top the Billboard 200 charts, and dethrone global phenom Taylor Swift's YouTube record for the biggest music video debut, would have been met with some skepticism. But the Bangtan Boys, or BTS as they are popularly called, have managed to accomplish all three feats, proving beyond doubt that music is a “universal language” which transcends across countries, languages, and cultures.

Powerful Earthquakes Trigger Deadly Tsunami in Indonesia

By on

The Southeastern nation of Indonesia, which sits on the Pacific Ring of Fire, is no stranger to earthquakes, many of which trigger tsunamis – powerful waves capable of immense destruction. However, the towering 18-foot wave that crashed into the island of Sulawesi on September 28, 2018 is one of the deadliest to hit the country in recent years.

Rare Two-Headed Copperhead Snake Found In Virginia Is A Social Media Sensation

By on

Found all the way from New England to West Texas and northern Mexico, copperhead snakes, which get their name from their reddish-brown heads, are the most commonly seen snakes in North America. Hence, a sighting of the venomous reptile is not earth-shattering news, unless, of course, you happen to find one with two heads! Believe it or not, that is what a Woodbridge, Virginia homeowner stumbled upon while tending to her flowerbed on September 20, 2018.
