A massive dust cloud that had been journeying 5,000 miles from the Sahara Desert across the Atlantic Ocean since June 15, 2020, finally hit the United States mainland on June 26, 2020. Nicknamed "Godzilla," the 3,500 mile-long plume broke into two chunks, thanks to the split in the mid-levels of the atmosphere....

With less than 55,000 grizzly bears left in the wild across North America, the sighting of even one is a cause for celebration. Hence you can only imagine how delighted Cara Clarkson and her family were when they spotted two young grizzlies — one with rarely seen all-white fur— foraging alongside the Trans-Canada Highway near Banff, Canada, on April 26, 2020....

June 19, 2020, marks the 155th anniversary of Juneteenth — a mashup of June and nineteenth — the oldest-known celebration commemorating the end of slavery in the United States.

With the days getting increasingly longer and warmer, the Northern Hemisphere summer may seem to be well on its way. However, though the meteorological season, which evenly splits the 12 months of the year into four seasons, started on June 1, 2020, the astronomical summer will not begin until June 20, 2020. Called summer solstice, it is the day when the North Pole is most inclined towards the Sun, allowing residents of the Northern Hemisphere to enjoy the longest day (and shortest night) of the year. Conversely, Southern Hemisphere residents will celebrate the astronomical start of winter, or winter solstice, with the shortest day (and longest night) of 2020....

Identifying the chemical makeup of pigments used in ancient documents, paintings, and watercolors is critical to restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color manuscripts in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers from Portugal has finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple tint that helped bring ancient illustrations and texts to life....

As if the COVID-19 pandemic has not been difficult enough, 2020 has another "trick" in store for the residents of Southwest Virginia, parts of North Carolina, and West Virginia. This one will come in the form of millions and millions of noisy cicadas who are gradually emerging from their 17-year underground hibernation to spend the final few weeks of their lives mating and breeding. Dubbed Brood IX, the alien-like insects are expected to peak in mid-June, with as many as 1.5 million specimens emerging per acre. The visit, however, will be short-lived, and most will be gone by July....

Astronauts aboard the International Space Station (ISS) are always thrilled to welcome new crew members to the orbiting laboratory.

Here are a few innovative festivities planned for the holiday, which will be observed on May 25, 2020....

Given that each light-year — defined as the distance light travels in one Earth year — is about 6 trillion miles (9 trillion km), a black hole that lies 1,000 light-years away may not seem very close. However, to astronomers who are accustomed to cosmic distance scales, the recently-discovered HR 6819's black hole, which lies in the constellation Telescopium, is an extremely close neighbor....

British street artist Banksy is well-known for his controversial and often politically-themed artwork. However, his latest creation can only be described as heartwarming. The mostly black-and-white stenciled sketch, dubbed "Game Changer," features a young boy playing with a British National Health Services (NHS) nurse superhero toy. In the background, Batman and Spiderman action figures lie in a waste bin, indicating that the boy's new superheroes are the "game changers" of today — the millions of COVID-19 medical workers worldwide who are risking their lives daily to keep the rest of us safe....

Historians have long suspected that the Eastern Mediterranean Sea, a popular ancient shipping route, is home to numerous shipwrecks. However, seven decades of search by marine archeologists had failed to unveil any traces of the boats. That changed on April 21, 2020, when the Enigma Shipwrecks Project (ESP) team revealed the discovery of a dozen ancient trading vessels in the Levantine Basin, the easternmost part of the Mediterranean Sea....

The COVID-19 pandemic shelter-in-place mandates and the need for social distancing has changed our lives in unprecedented ways and put a damper on everything — from graduations to proms, milestone birthdays and even summer vacations. However, it has also helped raise awareness of the importance of family. Hence, it is not surprising that many Americans plan to go the extra mile to demonstrate their love and appreciation for the real-life superhero in their lives on Mother's Day, which will be celebrated on May 10, 2020....

The negative health impacts of plastic on both wildlife and humans have been well-documented. However, the versatile material, which is used for everything from grocery bags to drink bottles to food packaging, is hard to avoid. Experts estimate that of the 359 million tons of plastics produced annually worldwide, about 150–200 million tons end up in landfills or the environment. To make matters worse, the material derived from the small percentage of plastic that is recycled is of lower quality and can only be used a few times for items like clothing or carpets before it has to be discarded....

While the novel coronavirus is dangerous for everyone, it is particularly so for the first responders who are being exposed to the illness daily. In the US alone, almost 5,500 nurses, doctors, and other healthcare professionals have been infected with COVID-19. Of these, dozens have succumbed to the disease. Now, hospital workers worldwide may get some reprieve thanks to Spot, a semi-autonomous four-legged robot developed by Waltham, Massachusetts-based robotics company, Boston Dynamics....

Though considered a waste of time by some, sleep is essential for the health and wellbeing of humans. Over the years, researchers have found sleeping allows the body to repair and restore cells, get rid of irrelevant memories, and even help kids grow taller and obtain better grades. Now, it appears that snoozing for an average of 8 hours daily enables the brain to cleanse itself and get rid of harmful toxins....

When Robert Sullivan, a research associate at the New Mexico Museum of Natural History and Science in Albuquerque, found some dinosaur bones in 67-million year-old Cretaceous rocks in New Mexico's San Juan Basin, in 2008, he had little idea they belonged to a new raptor species. More significantly, the feathered dinosaur roamed southern North America just prior to the mass extinction event, when most raptors had already disappeared from the fossil record....

Earth Day, which is celebrated annually on April 22, is usually commemorated with outdoor activities demonstrating support for environmental protection. These include planting trees, collecting roadside or beach trash, and conducting, or participating in, recycling and conservation programs....

Over the years, paleontologists have been able to uncover many mysteries about human ancestors from unearthed skeletal remains. However, not much is known about their development and growth. because most hominin fossils are those of adults, and remains of developmentally young hominins are uncommon. Now, a perfectly-preserved partial skeleton of a Homo Naledi juvenile, who lived on Earth between 335,000 and 226,000 years ago, ​ is providing insights into how our ancient relatives may have aged....

The orbital spacecrafts, landers, and rovers sent to Mars under NASA's Mars Exploration Program (MEP) have provided invaluable insights into the red planet's topography, climate, and natural resources. However, finding any evidence of life has proved elusive. Now, the discovery of microbial growth found inside ancient, cold oceanic crust in the middle of the South Pacific is giving scientists hope that the proof may already be with us — we just need to know where to look!...
