Celebrated annually on the second Monday in October, Columbus Day honors Italian explorer Christopher Columbus's discovery of America. However, the federal holiday, which will be observed on October 14, 2019, has long drawn criticism due to the European settlers' brutal treatment of the Native American people. It has also been argued that America had already been "discovered" by the indigenous people when Columbus arrived....

Octopuses in the wild have often been observed changing their skin color and texture to avoid predators or to catch unsuspecting prey. Now, for the first time, a researcher has captured a spell-binding video of a cephalopod called Heidi rapidly changing into a multitude of colors while sleeping....

The Masai Mara Reserve is one of Kenya's most popular tourist attractions. Every year, thousands of people flock to the national park to glimpse of a variety of wild animals, such as lions and cheetahs, or to witness the majestic annual migration of over 1.5 million wildebeests to and from neighboring Tanzania. However, this September's human "stampede" is due to an unexpected animal — a zebra foal with polka dots!...

A female walrus demonstrated the lengths moms — animal and human alike — will go in order to protect their offspring when she sank a Russian research boat that came close to her calves.

An estimated four million people worldwide took to the streets on Friday, September 20, 2019, for the youth-instigated Global Climate Strike. The young protestors, and their adult supporters, marched along city streets or lobbied outside government buildings to urge leaders to take aggressive action against climate change. Some US companies, such as Ben & Jerry's, Etsy, and The North Face, also joined in the effort by closing their stores to allow employees to participate. Believed to be the largest-ever climate change rally, the September 20 strike will be followed by a similar event on September 27....

Fans of Scotland's mythical Loch Ness Monster, or Nessie, will be thrilled by the discovery of the remains of a massive look-alike elasmosaurus. Measuring 36 feet long (11 meters), from snout to tail, it is the largest specimen of the four-flippered sea giants — which inhabited Earth between 55 to 66 million years ago — on record....

Russia's Soyuz spacecraft, which has been ferrying all astronauts to and from the International Space Station (ISS) since NASA retired the space shuttle in 2011, typically carries a crew of three. However, the MS-14 capsule that blasted off from a Russian spaceport in southern Kazakhstan on August 22, 2019, had just one passenger — a humanoid robot named Skybot F-850....

When Leigh Love stumbled upon a bird's leg bone at the Waipara Greensand fossil site in New Zealand's South Island in 2018, he suspected that they might be those of an ancient penguin. With four other species discovered there, the area has been a hotbed for penguin remains from the Paleocene Epoch, which spanned between 66 million and 55 million years ago. What the amateur paleontologist did not realize was that the fossil belonged to the largest, hitherto unknown, penguin species ever found....

Artists are continually striving to find innovative ways to showcase their talent. Some, like Jackson Pollock, produce masterpieces by flinging pigments across the canvas, while others, like Iris Scott, paint with their bare fingers.
