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....

On Sunday, March 20, Amazon CEO Jeff Bezos, was observed behaving like a kid in a candy store — and for a good reason too. The beaming billionaire was among the first to be given the opportunity to pilot a 14-foot-tall mechanical robot, dubbed Method-2, at the opening of the Amazon-hosted MARS 2017 conference. Dedicated to Machine learning, home Automation, Robotics, and Space Exploration (hence the acronym MARS), the three-day invite-only event was attended by 130 guests from the business, entertainment, and robotics sectors....

American historian Laurel Ulrich once said, “Well-behaved women rarely make history.” In celebration of Women’s History Month, here are a few of the millions of brave women that have broken all conventional rules to make a difference in the world....

Always wanted to help fight climate change? Then join the Earth Hour party on Saturday, March 25 by turning off all lights from 8:30 — 9:30 PM local time. This small action, taken by hundreds of millions of people around the world, will make a dent in our efforts to reverse global warming. More importantly, it will demonstrate what can be achieved if we all unite to protect our planet....

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....

On March 10, Professor Robert Kelly was doing what the expert on South Korea does regularly — discussing a political situation on live television with a BBC News reporter via Skype. In this case, the topic was South Korean President Park Geun-hye's unprecedented March 9th impeachment for committing “acts that violated the Constitution and laws.”...

Residents of the US East Coast still recovering from last week’s record snowstorms will be happy to know that today is not just the first day of spring, but also the International Day of Happiness. First celebrated in 2013, this fun holiday was established by the United Nations (UN) to remind us that "the pursuit of happiness is a fundamental human goal."...

With its wide canopy of leaves, the majestic 50-feet tall manchineel tree that is native to the Caribbean, Florida, the northern coast of South America, Central America, and the Bahamas, looks particularly inviting, especially on a hot summer day. But you may be wise to heed the warning signs given that the deceptively innocuous tree holds the Guinness World Record for “the world’s most dangerous tree.”...

Every year on March 17, millions of people worldwide celebrate St. Patrick’s Day by participating in parades, wearing green, and searching for leprechauns in the hopes of finding gold. So who was this clergyman whose death anniversary is celebrated with such gusto, and how did the fun traditions associated with the holiday begin? Read on....

Even if math doesn’t rank high on your list of favorite subjects, chances are you still look forward to Pi Day. That’s because though the discussions may begin with Pi — the ratio of the circumference of a circle to its diameter — they invariably end with a piece or two of yummy pie! The event is commemorated on March 14 because though the irrational number (its decimal representation never ends and never repeats) has been calculated to over ten trillion digits, it is widely recognized as 3.14....

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!...

After a relatively calm 2016, Europe’s most active volcano — Mount Etna in Sicily, Italy — came to life on February 27. The eruption that occurred at about 6:00 pm local time from the relatively new Southeast Crater formed by a 1978 eruption lit up the dark Sicilian skies with fountains of bright orange lava. As is characteristic of all Mount Etna ejections, the lava stream was accompanied by Strombolian eruptions. The short-lived, explosive outbursts that are caused by trapped bubbles of gas escaping through the lava can reach heights of several hundred meters, making for a spectacular show....

On Sunday, March 12, most Americans will ‘lose’ an hour by moving their clocks forward sixty minutes. This small sacrifice that marks the start of Daylight Saving Time (DST) is designed to allow residents to enjoy longer days during the upcoming spring and summer months....

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....

About forty light years, or 235 trillion miles, away in the constellation Aquarius lies a planetary system with seven Earth-sized planets, at least three of which could be habitable. The exciting news was revealed to the public at a NASA press briefing and through the release of a study in the journal Nature on February 22....

In January 2016, Professor Mike Brown, the California Institute of Technology researcher who demoted Pluto to dwarf status, reported that he and some colleagues had discovered evidence of a ninth planet in our solar system. Dubbed Planet X, the gaseous giant believed to be two to three times the size of Earth, purportedly has a highly elliptical orbit and takes over 20,000 earth years to revolve around the sun. Though exciting, the find was based on computer simulations, which means that no one has ever seen this mysterious planet....

Two days before Valentine’s Day, 40 couples dressed in gorgeous wedding gowns and black tuxedos tied the knot at a mass wedding ceremony in Peru’s capital, Lima. Not impressed? How about if we tell you that the brides and grooms were dogs?...

A large otter the size of a wolf, roamed the wooded marshlands of China’s Yunnan Province about six million years ago. Xiaoming Wang, curator of vertebrate paleontology at the Natural History Museum of Los Angeles County in California, and her team arrived at this conclusion after an extensive study of fossils found in the 6.2 million-year-old sediment of the Shuitangba coal mine in Yunnan, China in 2010 and 2015....

Unmanned aerial vehicles, or drones, have tremendous potential to deliver emergency supplies to remote or disaster-struck regions. However, they are expensive to mass produce and often require special pads to launch and land safely. Additionally, the need for the aircraft to maintain enough battery life to return, cuts the delivery distance to half. But these issues may be history, thanks to an affordable and disposable drone that is designed for a one way journey....

Move over, Atlantis! A real lost continent has been discovered by a team of geologists led by Lewis D. Ashwal from the University of the Witwatersrand in South Africa. The scientists, who have named it Mauritia, believe that the landmass was once part of Gondwana, the supercontinent that included most of the landmasses in the modern-day Southern Hemisphere, and the Arabian Peninsula and the Indian subcontinent that are now part of the Northern Hemisphere....
