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....

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....

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....

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....

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....

New Zealand is no stranger to beached whales. Every year, rescuers help refloat many disoriented mammals that get stuck in the coastal waters or sand during low tide. However, last week’s simultaneous stranding of two pods, totaling over 650 pilot whales, in the shallow muddy waters of Golden Bay at the northwest tip of South Island is almost unprecedented. Local marine experts say it is the largest known whale stranding since 1985 when 450 of the mammals were found beached in Auckland, and the third largest on record....

Every February 14, people worldwide demonstrate their affection for family members, friends, teachers, and significant others with a gift or two. However, this display of love does not come cheap. The National Retail Federation say that 55% of Americans will celebrate Valentine’s Day this year, spending an average of $136.57 USD each. Though lower than the $146.84 USD expended in 2016, it will add a respectable $18 billion USD to the economy! It is no wonder that retailers love the holiday....

Wish to enjoy Super Bowl Sunday celebrations, but skip the NFL game? Then tune into Animal Planet’s Puppy Bowl! The idea to create a show that features puppies “playing” ball came about in 2005 when the programming team was brainstorming ways to attract viewers on Super Bowl Sunday. While filming the animals on a football field was initially suggested in jest, it resonated with the team. After all, who doesn't like watching cute puppies frolicking around?...

On February 5, an estimated 188.9 million Americans will tune in to watch the Atlanta Falcons and New England Patriots compete for the coveted title of National Football League Champion. Some will do it for the genuine love of the game, others to watch the half-time show or commercials that are a spectacle in their own right. However, for most people, it is an opportunity to either host or attend a party and socialize with family and friends....

For many of us, the mere thought of wiggling fingers approaching our rib cage or moving towards our underarms is enough to elicit squeals of laughter and giggles. However, while we all know that tickling makes us happy, Michael Brecht, a professor at Berlin’s Humboldt University, says, it is “one of the most poorly understood forms of touch.”...

When geologists from the University of Toronto discovered water dating back 1.5 billion years at the Kidd Mine in Ontario, Canada, in 2013, they thought they had hit the jackpot. However, digging further inside the world’s deepest base metal mine led to an even bigger discovery — water that has been locked in the earth’s crust for at least 2 billion years!...

At the recent Consumer Electronic Show in Las Vegas, Korean car manufacturer Hyundai unveiled three battery-powered Iron Man-inspired robotic suits. Though the stylish exoskeletons developed as part of the company’s “Next Mobility” initiative, will not enable users to soar in the skies like the superhero, it will give them earthly “super powers” like mobility, strength, and endurance....

Mention the word refugees, and the image that comes to mind is that of humans that have been forced to leave their countries due to war, persecution or natural disaster. Botswana, a landlocked country in Southern Africa, is facing a different kind of refugee crisis – one caused by the hundreds of thousands of elephants that have fled their homelands to escape ruthless poachers....

On Saturday, January 28, Chinese communities around the world will begin a two-week celebration to usher in the Chinese New Year. Also called the Spring Festival, the holiday whose dates are determined by the lunar calendar, is the grandest and most famous of all Chinese festivals. To enable residents to be with their families and friends, most employers in China give their workers at least seven days of vacation. Schools and universities are closed for an entire month....

On Friday, January 20, thousands of supporters gathered at the US Capitol in Washington D.C to witness the inauguration of Donald Trump as the 45th President of the United States. The 35-word oath of office to “preserve, protect and defend the Constitution of the United States” culminated Mr. Trump’s stunning trajectory from real-estate tycoon to holding the country’s highest office....

On January 20, after eight years in office, President Barack Obama, his wife, Michelle, daughters, Malia and Sasha, and dogs, Bo and Sunny, will leave the White House to President-elect Donald Trump. In his January 10 farewell address, the US leader reflected on his legacy and encouraged Americans to remain optimistic about the country’s future....
