Mini robots that can roll, fly, float, swim, and even come together to morph into a single machine, may seem like something straight out of a science fiction movie. However, if a team of NASA scientists has its way, the self-assembling Shapeshifter may soon be exploring treacherous distant worlds in search of alien life....

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....

Astronomers have long suspected that celestial bodies from other solar systems traverse through ours frequently. However, it is only recently that they have been able to identify some of these interstellar objects. The first, a remarkably fast-moving comet dubbed 'Oumuamua, was already making its way back home by the time it was spotted in October 2017, giving scientists little chance to study it in detail. Now, thanks to the sharp eyes of an amateur astronomer in Crimea, scientists will get a second chance to investigate similar comets with C/2019 Q4 (Borisov), which is currently making its way to our solar system....

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. The incident occurred on September 18, 2019, when a team of sailors and scientists from Russia's Northern Fleet and Geographical Society were sailing to Wilczek Island in the Arctic Ocean....

Shipworms, which munch through wood and help release essential nutrient stored within it, are incredibly beneficial for other marine animals. However, the saltwater bivalve mollusks have been known to sink boats and cause extensive damage to docks, piers, and other wooden structures. Now, researchers have uncovered a shipworm species of a different kind — one that has the potential to change the course of a river by gnawing through its limestone bedrock!...

With self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the final leg — the so-called last mile — of the delivery process, from the store or local distribution center to the customer. The latest to join the trend is e-commerce giant Amazon. Following a successful eight-month test run in Snohomish County, Washington, the company's Scout robots have been making the rounds of Irvine, California, since August 6, 2019....

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....

Princess Louisa Inlet, a fjord located 60 miles from Vancouver, Canada, is a spectacular stretch of remote wilderness. Accessible only by boat or plane, the 3.7-mile-long (6-kilometers) area is popular with outdoor enthusiasts who flock to admire the 120-foot-high Chatterbox Falls or to hike the numerous trails to other scenic features. Its dense forests are home to a wide variety of wildlife, including grizzly bears, mountain goats, and eagles. Now, thanks to an unprecedented crowdfunding campaign, the pristine land will be preserved forever for future generations to enjoy....

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....
