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....

Finding a rare or unusual coin in the spare change you receive from your local grocery store, gas station, or restaurant may sound a little far-fetched and even absurd. However, don't rule out the possibility, at least until the over one million collectible coins given to retailers across the country by US coin dealers in honor of the 96th National Coin Week (April 21, 2019 to April 27, 2019), have been discovered. Called the Great American Coin Hunt, this first-of-its-kind treasure hunt is designed to inspire a new generation of kids and adults to start coin collections of their own....

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....

Paleontologists had long believed that ancient humans used land bridges to migrate from one country to another. Hence, Luzon, the largest of the 7,641 islands that comprise the Philippine archipelago in the Western Pacific Ocean, appeared to be entirely out of reach for our ancestors. Now, there is evidence that a previously unknown human species managed to overcome the ocean currents and settle on the island between 50,000 and 67,000 years ago — around the same time as our species, the Homo sapiens and our closest ancestors, the Neanderthals, dwelled on Earth....

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....

Looking for a fun Earth Day activity? You may want to try plogging, or picking up litter while jogging. Odd as it may sound, the new "sport" is becoming extremely popular with runners worldwide, many of whom are posting images of themselves and friends holding bags of trash on social media....

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....

After almost twenty years in space — thirteen of which were spent making extraordinary discoveries about the Saturn system, including its rings and natural satellites — NASA's Cassini spacecraft finally ran out of fuel. However, shortly before plunging into Saturn's atmosphere on September 15, 2017, the probe completed one final important mission: six close flybys of tiny moons located inside, or near, Saturn's rings....

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.

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....

When a university intern stumbled upon a seven-foot fish washed up on the beach at the University of Santa Barbara's (UCSB) Coal Oil Point Reserve on February 19, 2019, scientists assumed it was the mola mola sunfish. One of the world's heaviest known bony fishes, the species, found in tropical and temperate waters around the globe, is common in the Santa Barbara Channel....

Over the last week, both the academic and celebrity worlds have been roiled by a college admissions scam, involving famous Hollywood actors, tech executives, and college coaches. On March 12, 2019, the US Department of Justice charged 50 individuals, including 33 affluent parents, with bribery, fraud, and false information, to get their kids admitted into some of the nation's most elite universities, including Stanford, Yale, and the University of Southern California (USC)....
