Ever since the US shuttle program ended in 2011, astronauts - both American and those from other nations - have been dependent on the Russian Soyuz spacecraft to go to and from the International Space Station (ISS). The reliance, which costs NASA $70 million for each trip, is expensive and also leaves astronauts in danger of being stranded in the event of a like the one experienced in October 2018. Now, thanks to SpaceX's successful Crew Dragon test mission, astronauts may soon have an alternate, more affordable, mode of transportation to the ISS....

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!...

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....

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....

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....

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....
