The health impacts of outdoor air pollution are well-known. But indoor air pollution, caused by emissions from building materials or even air fresheners, can be just as harmful. Yet, there are no widely-accepted methods to detect the toxins. But researchers at the University of Turku in Finland hope to change that with the help of tiny glowing worms....

Water is essential for life on Earth. Yet, scientists currently have comprehensive information on just a few thousand lakes worldwide. A NASA-led international mission plans to change that with the first-ever global survey of nearly all water on Earth's surface....

Egypt's Great Pyramid of Giza, which stands 481 feet (147 meters) high, is the world's tallest pyramid. But the world's largest pyramid lies half a world away in Cholula, Mexico. Tlachihualtepetl, or the Great Pyramid of Cholula, is about 217 feet (66 meters) tall with a base of 1,476 by 1,476 feet (450 by 450 meters). The pyramid boasts a total volume of 157 million cubic feet (4.45 million cubic meters). This is almost twice that of the Great Pyramid of Giza....

California's Yosemite National Park is famous for its ancient giant sequoia trees and massive rock formations. These include tEl Capitan and Half Dome. However, from mid-to-late February, the main draw is the Horsetail Fall. The seasonal waterfall flows over the eastern edge of El Capitan every winter. During the last two weeks in February, it often transforms into a stunning "Firefall." The natural phenomenon occurs around 5 to 15 minutes before sunset. It lasts just a few minutes....

A "replica" sword that had been gathering dust at Chicago's Field Museum for about a century was recently found to be an authentic artifact from the late Bronze Age. The 3,000-year-old weapon was found in the Danube River in Budapest, Hungary, in the 1930s. It was given to the Hungary National Museum but later acquired by the Field Museum. Here, the sword was mislabeled as a copy and placed in storage....

The first phonetic alphabet — where each symbol stands for a certain sound — is credited to the Canaanites. They lived in the Eastern Mediterranean over 2000 years ago. Over the years, archaeologists have found some of these symbols on old pottery pieces. Now, they have discovered the oldest complete sentence written in this alphabet on an ancient lice comb....

Despite technological advances, modern concrete structures start to crumble in just 50 years if not maintained. This contrasts sharply with Italian monuments that remain standing after over 2,000 years. Now, an international research team has finally uncovered how Roman concrete wonders continue to survive to this day....

A remote area in Antarctica has been identified as the "coldest place on Earth." According to NASA, the temperatures in the East Antarctic Plateau can dip to a bone-chilling -136° F (-93.3° C). That is several degrees colder than the previous low of -128.6° F (-89.2° C) set in 1983 at the Russian Vostok Research Station in East Antarctica....

Starting January 12, 2023, stargazers will get a once-in-a-lifetime chance to see a rare comet with a greenish hue. Astronomers discovered Comet C/2022 E3 (ZTF) in March 2022 when it was inside Jupiter's orbit. NASA scientists believe this may be the comet's first sighting. If the icy body did pass our planet previously, it was probably thousands of years ago....

Over the years, scientists have collected substantial information on the tiny-armed reptile itself. However, very little is known about how the vicious predator evolved. Now paleontologists at the Badlands Dinosaur Museum in North Dakota believe they may have found an essential missing link to the T. rex's lineage....
