In case it has slipped your mind, this Saturday is April 1st, or, as is popularly called, Fools’ Day. The origin of this fun day, when pranking people is encouraged, is hazy. Some believe the tradition began in 1582 when the world transitioned from the Julian calendar, which started the year in April, to the currently used Gregorian calendar. Others think it was to celebrate the start of spring. Though individuals often prank each other, it is corporations that really get into the spirit with elaborate gags. Here are a few that were credible enough to fool people for days....

While campaigning to be the 45th President of the United States, Donald Trump often referred to global warming as a “hoax” and promised Americans that, if elected, he would lift all “job-killing (climate change) restrictions.” On Tuesday, March 29, the US leader made good on his promise with an executive order that reverses many of the regulations the Obama administration put in place to protect the environment....

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....

Researchers have long maintained that we sleep to accomplish a neural or physiological function that cannot be completed when awake. Why else would higher animals waste a third of their lives sleeping when they could be doing more important things like looking after their families, working, or hunting? Some scientists believe sleeping helps recharge the body, while others think it is important for consolidating newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day....

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.”...

If some geologists have their way, world maps will soon be altered to reflect an eighth continent. Dubbed “Zealandia,” the landmass that lies east of Australia covers 1.9 million mi2 (4.9 million km2), or an area larger than the Indian subcontinent. The only catch? Over 94 percent of it is submerged in the southwest Pacific Ocean, with just the islands of New Zealand and New Caledonia, visible above sea level....

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....

The phrase “good things come in small packages” certainly appears to hold true when it comes to ants. The tiny creatures can survive floods by morphing into rafts, find their way home using an internalized GPS system, and even lift up to 20 times their body weight. In 2013, scientists discovered that the insects, whose brains are smaller than a quarter of a small pin’s head, could even use tools, a skill that was once believed to be the realm of “intelligent” species like humans and a select number of animals. Now, researchers from the University of Szeged in Hungary have discovered that when given a choice, the clever insects even have the smarts to select the most efficient tool for the job....

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....

In August 2013, billionaire entrepreneur Elon Musk released a 57-page white paper concept for Hyperloop — a supersonic mass transit system between high-traffic cities that lie within short distances. The founder of Tesla Motors and SpaceX envisioned it to be a frictionless system where pods inside low-pressure, vacuum-sealed tubes would transport passengers and cargo at up to 760 miles an hour — approximately the speed of sound. Powered by solar energy, it would be strong enough to withstand extreme weather and earthquakes....

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....

The steady increase in global temperatures has been particularly disastrous for the polar ice caps. Experts warn that if this trend continues, there will be no late summer ice in the Arctic region by the 2030’s. The most effective solution, of course, is to reduce our greenhouse gas emissions before it’s too late. But since that is not happening, scientists are frantically trying to come up with alternative ways to try to reverse the situation....

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....
