A holiday associated with a math concept may not seem that exciting, especially for those not fond of the subject. However, America's Pi (“π”) Day – observed annually on March 14 (3/14) to honor the ratio of the circumference of a circle to its diameter, widely recognized as 3.14 – is an exception. That's because the celebrations don't just include fun math activities, but also a slice, or two, of yummy pie!...

Carbon dioxide (CO2), released by activities like burning of fossil fuels such as coal, oil, and natural gas, is one of the biggest contributors to the greenhouse effect, responsible for global warming. Over the years, scientists have come up with several innovative solutions to capture the polluting gas. However, none have been practical enough to implement on a large scale. Now, researchers at RMIT University in Melbourne, Australia believe they may have finally found a feasible way to reduce atmospheric CO2 – turning the gas back into coal!...

When a falling liquid droplet hits a surface, like a raindrop hitting pavement, it either flattens and spreads out evenly, or produces a sharp-edged splash. Now, a team of Chinese researchers has created a surface which allows the descending liquid to rebound and swirl around like a graceful dancer....

Shelby, who plays Bella in the recent Sony Pictures release A Dog’s Way Home, has all the traits of a celebrity pooch: bright, golden eyes, expressive eyebrows, and a big, brown nose. However, the pit bull mix did not always seem destined to be a movie star. About two years ago, Shelby was a stray puppy who lived on the streets and spent her days digging through trash for food scraps....

Here is some good news for the thousands of North Americans affected by this year's harsh winter - March 20, 2019 is the first day of spring! In anticipation of the season's start, on March 10, 2019, most residents will “spring forward” by moving their clocks an hour ahead. Though the start of Daylight Saving Time (DST) entails sacrificing sixty minutes of precious sleep or play time on Sunday, it allows for longer spring and summer days....

A walnut-sized bee with a wingspan of two and a half inches – about the length of a human thumb – may seem like something straight out of a science fiction movie. However, the Megachile pluto, or Wallace's Giant Bee, is not a figment of a movie writer's imagination, but a real insect that dwells in the Indonesian forests. While a few dead specimens of the bee have been discovered over the years, researchers have not seen a living one since 1981. Now, thanks to a team of dedicated American and Australian biologists, the magnificent bee has been photographed live in its natural habitat for the first time....

Virgin Galactic's founder, Sir Richard Branson, has been hoping to make space tourism a reality since 2008. While it has taken a little longer than the 18 months he had originally estimated, the company is getting increasingly closer to accomplishing its mission. On December 13, 2018, Virgin Galactic's suborbital spaceliner, VSS Unity, made history with the longest rocket-powered flight when it soared to the edge of space, 51.4 miles (82 km) above sea level. On February 22, 2019, the aircraft repeated the feat, this time with its first passenger – the company's astronaut trainer Beth Moses - on board....

The fact that the Earth's magnetic poles are continuously in flux has been known for over 400 years. However, scientists have usually been able to accurately predict their pace for five years. But earlier this year, when researchers at NOAA and the British Geological Survey conducted their annual check to gauge the accuracy of their forecast, they realized the north magnetic pole had moved much faster than expected. Fearing the unforeseen deviation would cause problems for military and ocean navigation, the experts updated the World Magnetic Model (WMM) on February 4, 2019, almost a year ahead of schedule....

Experts estimate that Earth gets bombarded with thousands of pieces of cosmic debris each year. While most burn up in the atmosphere, a few hundred survive and hit the planet's surface annually. While the impact of the space rocks, which come hurtling down at rapid speeds, has thus far been minimal, the possibility of an asteroid landing in a densely populated area and causing severe damage cannot be ignored....

The severe winter storm that pummeled parts of Washington, D.C. with as much as six inches of snow on February 20, 2019 had most residents scrambling for the safety and warmth of their homes. However, Smithsonian's National Zoo's giant panda Bei Bei was not among them. The adorable three-year-old had the time of his life playing in the mounds of fresh powder that helped Washington, D.C. retain its stature as the snowiest major city on the US East Coast this year....

Experts assert that if food were a country, it would rank third behind China and the US as one of the biggest greenhouse gas polluters. The reason is the ever-rising demand for meat. Livestock farming is responsible for 14.5 percent of global methane emissions. While cows are the worse offenders, pigs, sheep, and other animals contribute as well....

An elderly female, believed to have inhabited Earth approximately 3.67 million years ago, is causing a stir among paleontologists. If researchers from South Africa's University of Witwatersrand are right, the skeleton, nicknamed "Little Foot" due to its tiny ankle bones, represents a new species of an early human....

The budget battle between US lawmakers that led to the longest government closure in the country's history has finally ended. On Friday, February 15, 2019, President Donald Trump signed legislation, approved by Congress to fund the government through September 30, 2019, preventing a new shutdown set to begin on Saturday, February 16, 2019....

While any sighting of the critically-endangered leopard deserves mention, that of a black leopard is particularly newsworthy. What makes the specimen, recently captured on camera in Central Kenya by San Diego Zoo researchers and British wildlife photographer Will Burrard-Lucas, unique is that it is the first scientific documentation of such a creature in Africa in nearly a century. Prior to this, the only confirmed sighting was a 1909 photograph taken in Addis Ababa, Ethiopia....

Dutch designer Daan Roosegaarde has spent much of his career seeking artistic solutions to solve our environmental woes. His past projects include "Bioluminescent Trees" to light streets, a "Smog-Free Tower" to clean Beijing's polluted air, and "Gates of Light," which uses the headlamps of passing cars to illuminate the 60 floodgates of the Afsluitdijk, a major dam and causeway in the Netherlands. Now, the creative artist is hoping to use his skills to solve a pressing global issue - space junk!...

Venezuelan residents are in the midst of an unusual political crisis. Since January 23, 2019, the country has had two presidents: Nicolàs Maduro, the incumbent who was reelected in May 2018 and sworn into office on January 10, 2019, and Juan Guaidó, President of the National Assembly, an elected temporary parliament with the mandate to draft or reform the Constitution. The 35-year-old Guaidó, who leads the progressive Popular Will political party, proclaimed himself the country's interim leader on the grounds that the May 2018 elections were rigged, and hence the presidency was vacant....

In 2018, at the tender age of 12, Liu became the youngest to compete in, and win, the U.S. junior championships. That same year, she was also the youngest woman ever to land a triple axel in an international competition....

Last week’s record-breaking cold snap, which brought many US cities to a standstill, finally ended on February 2, 2019. Residents all the way from southern New England to the Upper Midwest breathed a sigh of relief as temperatures rose to a “balmy” mid-40s and low 50 degrees Fahrenheit. Even better, that same day, world-famous groundhog Punxsutawney Phil failed to see his shadow, which means that spring is a mere six weeks away!...

Pesky as they may be, ants are truly incredible insects. The tiny creatures can survive floods by joining together to morph into living rafts, predict earthquakes, lift up to 20 times their body weight, and even select the best tool to complete a job efficiently. Now, it appears that the elusive Dracula ant (Mystrium camillae) can snap its jaws shut at a mind-boggling speed of 90 meters per second (more than 200 miles per hour) – the fastest-known animal movement on record....
