Sleep, considered a luxury by many, is essential for a person's wellbeing. Researchers have found that insufficient sleep increases a person's risk of developing severe medical conditions, such as obesity, diabetes, and cardiovascular disease. Now, a new study by Boston's Massachusetts Institute of Technology (MIT) has found that getting sufficient sleep is also the key to improving academic performance.
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.
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!
On September 24, 2019, Nancy Pelosi, the Speaker of the US House of Representatives (House), launched a formal impeachment inquiry into President Donald Trump. The investigation was triggered by allegations that Mr. Trump had asked Ukrainian President Volodymyr Zelensky to look into the business ties of 2020 Democratic presidential candidate Joe Biden's son, Hunter. Allegedly, in order to persuade Zelensky to agree, the US president withheld federal military aid from Ukraine. So how will the impeachment process work, and what are its potential long-term implications for the president? Read on . . .
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.
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.
