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 . . .
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!
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.
When the curators at the National Gallery in London, England, applied imaging technology to Leonardo da Vinci's famous painting, The Virgin of the Rocks, they fully expected to see a sketch underneath. What they had not anticipated, however, was a drawing that was substantially different from the final masterpiece.
Swimming across the English Channel — the 21-mile-long body of water separating southern England from northern France — is no easy feat. In addition to the strong ocean currents, swimmers also have to endure temperatures that can range from a chilly 64 degrees Fahrenheit (18 degrees Celsius) to a near-freezing 42 degrees Fahrenheit (6 degrees Celsius). However, don't tell that to Sarah Thomas. The 37-year-old American recently became the first person ever to swim across the length of the treacherous stretch of water, which links the southern part of the North Sea to the Atlantic Ocean, not once, but four times non-stop!
Bees are essential for the pollination of flowers, fruits, and vegetables. Sadly, over the past 15 years, the global population of the industrious insects has been declining at alarming rates. Bee Informed Partnership, a collaboration of American insect experts, estimates that between April 1, 2018, and April 1, 2019, the country's managed bee population decreased by 40.7 percent. The numbers are as dire worldwide. Now, some cities in the Netherlands are coming up with innovative ideas to help stem the population decline of these all-important insects.
Sending a distress message in a bottle would not typically be considered a sensible strategy. However, it miraculously worked for three hikers from Morro Bay, California, who found themselves stranded atop a 40-foot waterfall at the Pfeiffer Big Sur State Park on California's Central Coast.
Australia’s Great Barrier Reef, home to over 1,500 fish species and countless other marine animals, is in trouble. Rising ocean temperatures, attributed to climate change, have destroyed about half of its coral since 1998. On August 30, 2019, the Great Barrier Reef Marine Park Authority downgraded the ecosystem's condition from "poor" to "very poor" and warned that the window of opportunity to save it was rapidly closing. Now, some scientists are hoping that a gigantic piece of pumice stone currently floating towards Australia will aid in the recovery of the world's largest coral reef system.
