Birding experts say your outdoor space could be missing several key elements.

Las Vegas is not a good environment for a toucan to be in the wild with its too-hot summers and cold winters, said Donald Price, a professor and biologist at the University of Nevada in Las Vegas who studies how winged animal species adapt to different environments.

Red Rock Canyon draws climbers from around the world, offering towering sandstone cliffs just minutes from the Las Vegas Strip. However, after rainfall, those iconic red walls can be more dangerous than they appear — even when the rock looks dry. According to Zach Perzan, an assistant professor of geology at the University of Nevada, Las Vegas, the sandstone at Red Rock — known as Aztec sandstone — is made up mostly of quartz grains held together by a relatively small amount of natural cement.

Rising temperatures, diminished rainfall and steadily increasing usage have taken a serious toll on the Colorado River and the water it contains. Some question whether the Las Vegas Valley will have enough water to last into the future.

When someone talks about frozen water, they typically mean the ice cubes in a cold drink or the vast glaciers in Earth’s coldest corners. What most people don’t know, however, is that H2O molecules can arrange themselves into many different types, or phases, of ice with various structures. Researchers have discovered more than 20 of these phases, the latest of which—called Ice XXI—a team recently created under extreme pressure, allowing water to turn to ice at room temperature.

Gold briefly topped $5,100 per ounce for the first time Monday, and as the fifth-highest gold producer in the world, this is good news for Nevada. With gold hitting a record on the global market, for Nevada, this means more jobs, more tax revenue and more gold exploration, according to mineral and mining experts.

Chances are that all your encounters with frozen water—while trudging through slushy winter streets, perhaps, or treating yourself to cool summer lemonades—have been confined to one structural form of ice, dubbed Ih, with the h referring to its crystal lattice’s hexagonal nature. But there is so much more to ice than that.

At the start of the year, Earth will quietly reach a milestone in its orbit around the sun. Known as perihelion, this is the moment when our planet is closer to the sun than at any other point in the year.

Water is all around us, yet its surface layer—home to chemical reactions that shape life on Earth—is surprisingly hard to study. Experiments at SLAC's X-ray laser are bringing it into focus.

If you’ve been following astronomy headlines, you might have noticed a curious new arrival to the neighborhood: Comet 3I/ATLAS. It’s not just another “regular” comet from the outer solar system–this one’s an interstellar visitor, meaning it was born around another star entirely.

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of cosmic collisions. The twin discoveries, labeled GW241011 and GW241110, were announced by the international LIGO, Virgo, and KAGRA collaborations—teams that have been tuning their instruments to detect the faintest ripples in space and time. Each signal, lasting less than a second, was a final whisper from black holes that collided billions of years ago.
