Over the years, researchers have unearthed fossils of many of the estimated 2,468 dinosaur species that roamed Earth during the Mesozoic era, which spanned from between 252 million years ago to about 66 million years ago. However, few can compare to the discovery of Oculudentavis khaungraae, the smallest dinosaur ever known to live on the planet....

Celebrated annually on March 14, Pi ("π”) Day is a universal favorite with students and teachers. Though the American holiday, which honors the numerical constant representing the ratio of a circle's circumference to its diameter, typically begins with a classroom discussion of the symbol, it usually ends with a slice or two of delicious pie. The event is commemorated every March 14 because the irrational number, which continues infinitely without repetition or pattern, is widely recognized as 3.14....

March 3, 2020, marked the most significant day of voting in the Democratic Party's 2020 presidential nomination fight.

It might be our closest star and absolutely essential for our existence, but, for the most part, the inner workings of the Sun remain a mystery to scientists. However, if the inaugural close-up of our star captured by the world's most powerful telescope — the Daniel K. Inouye Solar Telescope (DKIST) — is any indication, that may soon be a thing of the past....

If you have felt the skies above you seem increasingly empty of chirping birds, you are not alone. A 2018 study by BirdLife International revealed that 40 percent of the world’s 11,000 bird species are in decline, and one in eight bird species is threatened with global extinction. Now, some scientists are using cutting-edge technology to revive the critically-endangered kākāpō; if successful, the techniques used may help save other bird species as well....

Though bushfires are a common occurrence in Australia during the summer, they have never been as devastating or as widespread as the ones currently burning across the country. Since September 2019, the blazes, fueled by dry foliage and strong winds, have scorched over 15.6 million acres (24,000 square miles) — an area larger than the state of West Virginia. Even worse, officials warn that Australia's wildfire season — which generally lasts through March — is nowhere near its end....

However, the impeachment process is far from over. Here is how we got to this moment and what to expect next....

The low percentage of women in science, technology, engineering, and mathematics (STEM) careers is often attributed to men being believed to be better at the sort of thinking those fields require. Though several studies have debunked the myth, they have largely been based on results acquired from various standardized tests. Now, researchers from Pennsylvania's Carnegie Mellon University have found evidence that is hard to overlook: brain scans proving that young girls and boys use the same mechanisms and networks in the brain to solve math problems....

While an estimated 46 million turkeys will be taking center stage at Thanksgiving dinner tables around the US on November 28, 2019, two lucky birds will be happily cackling in retirement. On November 26, 2019, President Donald Trump used his executive powers to pardon North Carolina-born fowls "Bread" and "Butter" from the chopping block. The Presidential Turkeys will spend the rest of their lives with Peas and Carrots, last year's pardoned birds, at Gobblers Rest at Virginia Tech in Blacksburg....

Venice, which is built on 118 small islands in the middle of the Venetian Lagoon at the tip of the Adriatic Sea in Northern Italy, is no stranger to floods. The picturesque city experiences water surges from the rising tides at least four times a year, usually during winter....

Though thousands of adventurers have scaled Mount Everest, the highest and most famous of the world's 14 tallest mountains, only 40 climbers have conquered them all. Located in Asia's Himalayan and Karakoram ranges, the "eight-thousanders" each stand over 8,000 meters (26,247 feet) tall, above the so-called "death zone," where the amount of oxygen is insufficient to sustain human life for an extended period....

California's relatively calm fire season ended in mid-October with several simultaneous blazes that have since scorched thousands of acres and destroyed hundreds of structures. The largest fire, the Kincade Fire, has burned through 80,000 acres and obliterated 370 structures, including 141 homes, in Northern California since October 25, 2019. In Southern California, the Maria Fire, which broke out in Santa Paula, Ventura County, shortly after 6 p.m. on October 31, 2019, has chewed through 10,000 acres and threatened the area's tens of millions of dollars' worth of avocado and lemon crops....

On Sunday, November 3, 2019, most North Americans will mark the end of Daylight Saving Time (DST) by moving their clocks back an hour.

In 1893, Arctic explorer Fridtjof Nansen deliberately lodged his wooden ship in the sea ice north of Siberia, hoping that its natural drift would take him to the North Pole. Though the Norwegian scientist failed to reach his desired destination, his three-year-long, 2,000-kilometer journey into the North Atlantic Ocean revealed important data about the then-mysterious Arctic Ocean. Now, an international team of researchers have embarked on a similar journey for a groundbreaking climate change study of the Arctic....

Boyan Slat has been dreaming of cleaning up the world's oceans ever since he was a teenager. On October 2, 2019, the now 25-year-old announced that System 001/B, an autonomous retrieval system developed by his non-profit Ocean Cleanup, had successfully trapped plastic debris floating in the Great Pacific Garbage Patch. Located between Hawaii and California, the approximately 617,763 square-mile mass of waste is the largest accumulation of ocean plastic in the world....

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 . . ....
