When Robert F. Smith rose to address the 400 graduates of Atlanta's Morehouse College on May 19, 2019, the students expected the commencement speaker to be entertaining, inspiring, and encouraging. What they did not expect, however, was that he would change their lives forever by pledging to pay off all their student debt....

Jeff Bezos, the founder of Amazon and the world's wealthiest person, was just five years old when Neil Armstrong and Buzz Aldrin stepped on the lunar surface on July 20, 1969. However, he has never forgotten the grainy black-and-white footage from the historic moment. Since then, the moon has always been the center of the entrepreneur's space-faring ambitions which are channeled through his self-funded spaceflight company, Blue Origin....

In most democratic countries, all voters go to the polls on a single, predetermined day. However, this is not the case in India, the world's largest democracy and the planet's second most populous country after China. In this diverse subcontinent — which boasts 22 official languages, 200 regional languages, and over 6000 dialects across its 29 states and 7 Union territories — voting is an elaborate process, conducted in seven stages over a period of 39 days. Held every five years, this year the general elections began on April 11, 2019 and will continue until May 19, 2019, with the final results announced on May 23, 2019....

Though Thailand has been a constitutional monarchy since 1932, the country's king is considered the spiritual protector of its people and culture. For seventy years, that role had been fulfilled by King Bhumibol Adulyadej. When the beloved monarch passed away in October 2016, his second child, and only male heir, crown prince Maha Vajiralongkorn, ascended to the throne. However, in respect to the highly-revered former king, the country observed a three-year mourning period, postponing the new monarch's coronation ceremony until early May 2019....

Mention the word spy, and the images that come to mind are those of secretive, stealthy fictional characters like British Secret Service agent James Bond and former CIA assassin Jason Bourne. However, the alleged Russian mole, who recently "defected" to Norway, fits none of those descriptions. In fact, it is not even a person, but a friendly Beluga whale who loves to interact with humans!...

As if being downgraded to dwarf planet status was not enough, Pluto may now be in danger of losing its wispy atmosphere by 2030. The dire prediction comes from a 28-year study of the small celestial body, which lies at the edge of our solar system, by a team of international researchers led by University of Tasmania astronomer Andrew Cole....

Every year on Mother's Day, which will be celebrated on Sunday, May 12, 2019, Americans honor the real-life superheroes in their lives with special treats and extravagant gifts. Hence, it is not surprising to hear that Mother's Day is the third-largest US retail holiday, behind only the winter holidays and back-to-school season. According to a survey conducted by the National Retail Federation (NRF), this year, the spending will escalate to a record $25 billion, up substantially from the $23.1 billion earned by retailers in 2018....

After being eradicated for over 19 years, measles is making a comeback in America. Since January 2019, the highly-contagious disease has infected more than 700 people, mostly small children. The cases have emerged across the country, all the way from New York, which is facing its worst measles crisis since 2000, to Washington and California. According to the American Red Cross, as of April 26, 2019, 22 states have reported measles cases, and the number seems to be increasing daily. So what is measles, and why is the outbreak causing such anxiety? Read on . . ....

Teachers don't just educate students — they also act as counselors, problem-solvers, and in some cases, even social workers to help kids in need. Yet, these incredible individuals, who inspire kids to dream big and help them reach their potential, are often unappreciated and overlooked. To change that, since 2014, the Varkey Foundation — established to improve standards of education and raise the status and capacity of teachers worldwide — has been honoring the world's "real superheroes" with an annual $1 million Global Teacher Prize. This year's award, presented in a star-studded ceremony hosted by Hollywood actor Hugh Jackman in Dubai, UAE on March 24, 2019, went to Peter Tabichi from Kenya, Africa....

While rain on Earth is associated with water, precipitation on the Sun comes as giant clumps of plasma, or supercharged gas, which drizzle down from the star's atmosphere on to its surface. Though coronal rain has been observed on numerous occasions, its source, which researchers believed would help them better understand how the Sun's outer atmosphere, or corona, gets so hot, had never been discovered. Now, thanks to Emily Mason, a graduate student at The Catholic University of America in Washington, D.C., the mystery has finally been solved....

Given that even a six month stint at the International Space Station (ISS) causes astronauts to lose bone density and, in some cases, results in visual impairment, researchers have wondered if the human body can withstand a mission to Mars, which could take up to three years. Now, a groundbreaking study involving American twin astronauts Mark and Scott Kelly has found that while the body undergoes drastic changes when exposed to the weightless environment and space radiation for long durations, it mostly reverts to normal upon returning to Earth. This has led the experts to conclude that astronaut health can be "mostly sustained" for a year in space....

On Monday, April 22, 2019, corporations worldwide will encourage employees to celebrate Earth Day by participating in activities like neighborhood or beach clean-ups, planting trees, or biking/walking to work. While the one-day enthusiasm to care for our planet certainly helps, to make a real difference, companies have to incorporate sustainability into their everyday operations. Here are a few businesses that are making an impact beyond Earth Day....

No visit to the beautiful city of Paris, France is complete without a visit to the Notre Dame de Paris or, as it is commonly called, Notre Dame. The medieval cathedral, built over 180 years — from 1163 to 1345— is one of the world's most stunning examples of Gothic architecture. Unfortunately, on April 15, 2019, the 850-year-old monument, which is visited by over 13 million people annually, was engulfed in a massive blaze that caused widespread damage to the iconic structure....

Easter, which falls on April 21, 2019 this year, is the oldest and most important of all Christian festivals. Many adults commemorate the holiday, which celebrates the resurrection of Jesus Christ, with prayers and by fasting for 40 days prior to the event. However, for most American kids Easter is all about feasting on delicious food, enjoying springtime parades, and, best of all, participating in neighborhood egg hunts. But while these traditions are a norm in the US and other countries, such as the United Kingdom and Canada, not every country observes the occasion by looking for candy-filled eggs. Here are a handful of fun rituals that you may be tempted to incorporate into your own Easter celebrations this year....

Researchers have long known that the ancestors of the mighty whales were nimble, four-legged creatures that were comfortable both on land and in the sea. However, given that the only evidence of the early mammals had been found in present-day Pakistan, India, and parts of Africa, scientists were unsure of how the mammals had dispersed to the Western Hemisphere. Now, thanks to the aptly-named Peregocetus pacificus (P.pacificus), or "traveling whale that reached the Pacific," paleontologists finally have an answer to this all-important migration mystery....

The existence of black holes, first proposed by Albert Einstein in his 1916 general theory of relativity, has been known for decades. However, astrophysicists have thus far relied on indirect evidence, such as the stars orbiting a large and invisible object in the center of the Milky Way galaxy, to prove their presence. That changed on April 10, 2019, with the release of the first-ever direct visual evidence of a black hole in the center of the galaxy M87, located 55 million light-years from Earth....

While even the mention of a shark swimming close to shore is enough to send residents scurrying for cover, the "WasteShark" is being welcomed with open arms. The brainchild of South African entrepreneur Richard Hardiman, the aquatic drone is designed to devour all floating debris, including plastic and other non-biodegradable trash, that has accumulated along coastal waters, before it drifts out to sea....

Over the years, NASA has successfully deployed several rovers, landers, and orbiters to Mars. While the science laboratories continue to provide invaluable data about the Red Planet, their limited, or zero — as is the case with landers — mobility, restricts the space exploration vehicles to areas close to the original landing site. To obtain a more comprehensive view of Mars, the US Space Agency plans to send a fully-autonomous miniature test helicopter with the Mars 2020 rover, scheduled for launch in July 2020....

Termites are famous for their superior architectural skills. The mounds created by the industrious insects contain an elaborate network of tunnels with a series of chimneys that help regulate oxygen levels, temperature, and humidity to ensure the queen, who sits in a chamber underneath, is comfortable....

On March 10, 2019, eight-year-old Tanitoluwa "Tani" Adewumi defeated 73 young competitors to win the New York State Scholastic Chess Championship in his age category — kindergarten to third grade — with five wins and one draw. While the achievement is remarkable in itself, what is even more so is that the youngster, who was homeless at the time, began learning the game less than a year ago....

For pranksters and joke lovers, there is no better day than April 1. Often called April Fools' Day, it is the one day of the year when light-hearted tricks are not only expected but also welcomed by all. Some believe the fun holiday began in 1582 when the world transitioned from the Julian calendar, which celebrated the New Year on the last week of March, to the current Gregorian calendar. Those unaware of the change, or refusing to accept the January 1 start date, were often mocked and had jokes played on them on or around the old New Year. Others speculate the holiday began as a joyful way to welcome spring....

Female mosquitoes, which feed on human blood to obtain iron and amino acids required to produce eggs, are notorious for transmitting viruses responsible for deadly diseases, such as yellow fever, Dengue, and Zika. Over the years, researchers have devised various solutions, ranging from repellents to vaccines to genetic engineering, to combat the vectors. Now, a team at New York's Rockefeller University has come up with a unique solution to fend off the dangerous insects - filling their little bellies with diet drugs to curb their appetite for human blood....

Swimming in water temperatures of 41 degrees F and below, with air temperatures between 6.8 degrees F to -4 degrees F, wearing just a swimsuit, cap, and goggles, may sound foolhardy to some. But that is precisely what 400 athletes from 33 countries had to endure in the 3rd biennial International Ice Swimming Championships, held in Murmansk, Russia from March 14, 2019 to March 17, 2019....
