Though plastic shopping bags are incredibly cheap and useful, their disposal causes widespread pollution. That's because the non-biodegradable polyethylene takes centuries to decompose and is also detrimental to wildlife who often mistake the colorful debris for food. Now, we may have an unlikely ally to help clean up our trash – a small wax worm bred primarily for use as premium fish bait....

Memorial Day, which will be celebrated on Monday, May 29 this year, is one of the most important holidays in the American calendar. Observed annually on the last Monday of the month, it honors the men and women who have died while serving in the United States Armed Forces. Though the tradition is believed to have been started by local communities in the late 1800’s, the first official Memorial Day celebration is credited to Waterloo, New York. On May 5, 1866, the town’s residents organized a community-wide event to pay respects to perished soldiers by decorating their graves with flowers and flags....

As you are firming up your summer plans, you may want to pencil in the total solar eclipse on August 21. Dubbed the ‘Great American Eclipse,' it is not just the first total solar eclipse visible from the contiguous United States since February 26, 1979, but also the first that can be seen across the country, from the Pacific to the Atlantic, in almost a century. The last time the celestial phenomenon was experienced coast-to-coast was on June 8, 1918!...

Forty-seven years ago, on April 22, 1970, twenty million Americans took to the streets to voice their concern about the deteriorating environment and urge the government to take action before it was too late. The grassroots movement, which is now celebrated by over 2 billion people in 192 countries, led to the enactment of numerous environmental laws, including the Clean Air Act of 1970 and the Endangered Species Act of 1973....

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."...

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....

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....

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....

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!...

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....

Chronic or compulsive lying has largely been considered a mental illness. However, a new study from the University College London suggests that there may be a biological explanation as well. The researchers believe that small, self-serving lies desensitize our brains to the negative emotions connected to dishonesty, paving the way for bigger lies....

The thorny devil, named for the sharp spikes that cover its head and body, is a lizard that dwells in the Australian Outback’s hot and arid desert. Though its scary appearance has earned it other equally alarming names like the thorny dragon or the mountain devil, the palm-sized reptile is a harmless, slow-moving animal that has managed to adapt to one of the world’s most inhospitable environments. While researchers know a lot about these hardy lizards, the one mystery that had never been completely solved, is how they keep hydrated....

On Sunday, December 4, Fidel Castro, Cuba’s former President and leader of the Communist revolution, will be laid to rest at the Santa Ifigenia cemetery in Santiago de Cuba, the island's second-largest city. Fidel, who passed away on Friday, November 25 at age 90, ruled the country with an iron fist for 47 years (1959-2006) and was one of the most controversial leaders of our time. Supporters maintain that Fidel was a champion of socialism and think his revolutionary regime protected Cuba from American imperialism. Critics, which include his daughter Alina Fernández, considered him a dictator who allowed human rights abuses and impoverished the country’s economy....

The Hubble Space Telescope that has been orbiting the Earth since 1990, has and continues to reveal the secrets of planets, stars, and galaxies that lie trillions of miles away. In 2018, it will finally be retired and replaced by the larger, and more powerful, James Webb Space Telescope (JWST). The announcement, made by NASA on November 2, culminates a 20-year quest to build a state of the art telescope that cost $8.7 billion and required the construction of new assembly and testing facilities...

The last time Chicago Cubs fans had something to celebrate about was in 1908 when the baseball team won the World Series for the second consecutive year against the Detroit Tigers. Though the Cubs went on to appear in seven World Series thereafter, they came up empty each time. The 108-year drought, the longest by any major American sports team, finally came to an end after an 8-7, 10-inning victory over the Cleveland Indians in a thrilling Game 7 that began on Wednesday night (Nov 2) and ended early Thursday morning (Nov 3)....

With Halloween falling on a Monday this year, chances are you are feeling a little sleep-deprived. Here is some good news at least for those that live in North America.
