On June 23, 2016, the residents of the United Kingdom (UK) shocked the world by voting for the country’s exit from the European Union (EU), or “Brexit.” On March 29, almost nine months after the historic referendum, the country’s Prime Minister, Theresa May, began the official separation process with a letter to EU President Donald Tusk. It urged the remaining member states to allow the UK to leave “in a fair and orderly manner, and with as little disruption as possible on each side.”...

In 2006, the International Astronomical Union (IAU), which promotes and safeguards the science of astronomy, passed a resolution that classified all celestial bodies, (except satellites) in our solar system into three distinct categories – planets, dwarf planets, and small Solar System Bodies. To qualify as a planet, the body had to orbit around the sun, have sufficient mass for its self-gravity to pull it into a round shape, and have cleared the neighborhood around its orbit. Since Pluto did not meet the third criterion, it was downgraded to a dwarf planet....

Like the rest of their species, the Southern Hemisphere humpbacks, or Megaptera novaeangliae, are not social animals. The baleen whales typically prefer to remain solo or amalgamate in small groups which disperse quickly. However, since 2011, researchers from the Cape Peninsula University of Technology in Cape Town have been observing a new phenomenon off the coast of South Africa — large swarms of whales, comprising anywhere from 20 to 200 individuals. Professor Ken Findlay and his team reported seeing 22 instances of the large groups on three different occasions in 2011, 2014, and 2015....

As most people age, the crystalline lenses in their eyes start to stiffen and are unable to change shape as easily. As a result, objects in close range start to look blurry, forcing many middle-aged adults to carry reading glasses either around their necks or tucked away in a handbag. Those already suffering from nearsightedness, or myopia, a condition where distant objects appear blurry, have to depend on bifocals or, even worse, switch between two pairs of glasses. However, thanks to some Utah researchers there may finally be a solution — self-adjusting “smart” glasses....

Holi, the spring festival of colors that will be celebrated on Sunday, March 12, is one of India’s most anticipated events. Observed annually on the last full moon day of the Hindu calendar month of Phalguna, the two-day holiday entails taking to the streets early in the morning to douse strangers and friend alike, with colored powder and water. However, unlike the copycat color runs in the US, revelers do not have to race five or ten kilometers to participate!...

On February 21, after a week of feasting on her favorite treats that included a multi-tiered ice cake, giant panda Bao Bao started preparing for her one-way journey to China. The National Zoo resident began the morning with a hearty breakfast comprising 17 pounds (8 kg) of bamboo and 5.4 pounds (2.4 kg) of leafeater biscuits before heading out for some fresh air. Shortly after, she was put inside a custom-made, four-by-six, steel travel crate and transported to the Washington Dulles International Airport....

Winter means different things to different people. For some, it is the chance to cozy up to a warm fire, for others, a time to frolic in the snow. Then there are those that head to the Takhini Hot Springs in Yukon, Canada to participate in the wacky and hilarious International Hair Freezing Contest....

The about million species of insects known to humanity thus far have managed to neatly fit into one of 31 existing scientific orders. However, when George Poinar, Jr., the world’s leading expert on plant and animal life forms, found preserved in amber, saw the carcass of this 100-million-year-old insect, he knew it would require its own scientific order – an incredibly rare event....

While the world is still debating the safety of self-driving cars, the futuristic city-state of Dubai, in the United Arab Emirates, is preparing to launch an autonomous aerial taxi. Starting in July, commuters will be able to summon the world’s first passenger drone, the EHang 184, to transport them to their desired destination without having to deal with Dubai’s congested freeways....
