NASA's Landmark Twins Study May Pave The Way For A Mars Mission

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.

Fossils Of New Human Species Unearthed In The Philippines

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.

Corporations With Green Initiatives That Go Beyond Earth Day

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.

French President Emmanuel Macron Promises To Rebuild Fire-Ravaged Notre Dame Cathedral

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.

Beyond the Bunny: Easter Traditions From Around The Globe

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.

Remains Of Four-Legged Whale That Walked On Land Found in Peru

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.

Plogging: A Fun Activity For Earth Day And Every Day

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 First-Ever Image Of A Black Hole Is Stunning

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.
