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....

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....

The Atlantic hurricane season, which spans from June 1 to November 30, had been relatively calm this year, with just one major storm in July. That changed at the end of August, when Dorian, a Category 5 hurricane, came screaming through, leaving a trail of destruction all the way from the US Virgin Islands to the Bahamas and the US and Canadian east coasts....

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....

It is not uncommon for human-generated blazes — lit to clear the land out for farming or ranching — in the Amazon rainforest to get out of control. However, this year, the number of wildfires has been extraordinarily high. Brazil's National Institute for Space Research (INPE) has recorded over 73,000 fires in the world's largest tropical rainforest between January and August 2019, 2,500 of which are currently active. This is the highest number observed since the agency began keeping records in 2013, and an astounding 80 percent more than during the first eight months of 2018....

It is common knowledge that the droplets spread from sneezing are one of the key culprits responsible for transmitting infectious diseases between humans. Now it turns out that some plants have a similar ability to share the "love" and spread pathogens to each other. However, while sneezing in humans is an involuntary response to irritants along the lining of the nose, plants "sneeze" due to a quirk in fluid dynamics....

Japan, the host country of the 2020 Olympic and Paralympic Games, has promised to deliver "the most innovative Games ever organized." On July 24, 2019, a year before the competition begins in Tokyo on July 24, 2020, the Olympic Committee unveiled its first ingenious idea — medals made using precious metals extracted from discarded electronics....

BBC Earth host Lizzie Daly and underwater photographer Dan Abbott released several videos of exciting encounters with marine animals off the English coast from July 7 to July 13, 2019. The pair swam alongside gray seals off the coast of Northumberland, minke whales off the northwest coast of Scotland, and seabirds near Wales. However, the highlight came on the final day of the tour, when the underwater adventurers stumbled upon a massive barrel jellyfish off the coast of Falmouth, Cornwall. The sighting of the mesmerizing animal was a fitting way to end Daly's "Wild Ocean Week" campaign to raise ocean awareness and funds for the UK's Marine Conservation Society....

Since late March 2019, local fishers and sightseers on whale watching excursions along the Southern California Coast have been treated to a rare sight — dozens of school bus-sized basking sharks lumbering through the water. This is the first time the "gentle giants of the sea" have frequented the area in such large numbers in over thirty years....

After conquering the roads, Uber, the peer-to-peer ridesharing service, now has its eyes set underwater. On May 24, 2019 the American company launched scUber, “the world’s first ride-share submarine experience," which will take tourists on a memorable journey across the world's most extensive coral system — Australia's Great Barrier Reef....

Mention the word spy, and the images that come to mind are those of secretive, stealthy fictional characters like British Secret Service agent James Bond and former CIA assassin Jason Bourne. However, the alleged Russian mole, who recently "defected" to Norway, fits none of those descriptions. In fact, it is not even a person, but a friendly Beluga whale who loves to interact with humans!...

As if being downgraded to dwarf planet status was not enough, Pluto may now be in danger of losing its wispy atmosphere by 2030. The dire prediction comes from a 28-year study of the small celestial body, which lies at the edge of our solar system, by a team of international researchers led by University of Tasmania astronomer Andrew Cole....

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....

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....

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....

While even the mention of a shark swimming close to shore is enough to send residents scurrying for cover, the "WasteShark" is being welcomed with open arms. The brainchild of South African entrepreneur Richard Hardiman, the aquatic drone is designed to devour all floating debris, including plastic and other non-biodegradable trash, that has accumulated along coastal waters, before it drifts out to sea....

Termites are famous for their superior architectural skills. The mounds created by the industrious insects contain an elaborate network of tunnels with a series of chimneys that help regulate oxygen levels, temperature, and humidity to ensure the queen, who sits in a chamber underneath, is comfortable....

In early February 2019, 51-year-old Rainer Schimpf and his team set out to film South Africa's famous Sardine Run off the coast of Point Elizabeth. The annual migration of billions of Sardinops sagax, more commonly known as South African pilchards or sardines, is a big draw for predators, especially the Cape gannet, a beautiful, cream-colored seabird, and the common dolphin. The two species work together to herd the large group of fish and separate them into smaller shoals known as bait balls, which are then scooped up by not just the birds and the dolphins, but also other hunters such as copper sharks and Bryde's whales....

On Friday, March 15, 2019, hundreds of thousands of kids from over 80 countries, including the United States, Germany, and Malaysia, will skip school and take to the streets. However, the worldwide strike is not a protest against excessive homework or long school hours. It is a plea to government officials and business leaders to take immediate action against climate change....

A walnut-sized bee with a wingspan of two and a half inches – about the length of a human thumb – may seem like something straight out of a science fiction movie. However, the Megachile pluto, or Wallace's Giant Bee, is not a figment of a movie writer's imagination, but a real insect that dwells in the Indonesian forests. While a few dead specimens of the bee have been discovered over the years, researchers have not seen a living one since 1981. Now, thanks to a team of dedicated American and Australian biologists, the magnificent bee has been photographed live in its natural habitat for the first time....

Experts assert that if food were a country, it would rank third behind China and the US as one of the biggest greenhouse gas polluters. The reason is the ever-rising demand for meat. Livestock farming is responsible for 14.5 percent of global methane emissions. While cows are the worse offenders, pigs, sheep, and other animals contribute as well....

While any sighting of the critically-endangered leopard deserves mention, that of a black leopard is particularly newsworthy. What makes the specimen, recently captured on camera in Central Kenya by San Diego Zoo researchers and British wildlife photographer Will Burrard-Lucas, unique is that it is the first scientific documentation of such a creature in Africa in nearly a century. Prior to this, the only confirmed sighting was a 1909 photograph taken in Addis Ababa, Ethiopia....

Always wanted to experience the magical winter wonderland that Queen Elsa created in Disney's animated movie Frozen? Then you are in luck. Thanks to Utah-based company “Ice Castles,” acre-sized frozen fortresses are now a reality in six of North America's coldest regions: Dillon, CO, Excelsior, MN, Lake Geneva, WI, North Woodstock, New Hampshire, Midway, UT and Edmonton in Alberta, Canada....

Pesky as they may be, ants are truly incredible insects. The tiny creatures can survive floods by joining together to morph into living rafts, predict earthquakes, lift up to 20 times their body weight, and even select the best tool to complete a job efficiently. Now, it appears that the elusive Dracula ant (Mystrium camillae) can snap its jaws shut at a mind-boggling speed of 90 meters per second (more than 200 miles per hour) – the fastest-known animal movement on record....
