Even a single person in the snow can exert enough pressure on it to cause a buried weak layer of snow to collapse and the snow cover to slide away. In this case, experts speak of anticracks. The fundamental fracture properties that can lead to powerful slab avalanches are still largely unknown, but crucial in…
Floods and landslides killed 11 people after a fierce tropical storm dumped heavy rain on the Philippines for a second day, officials said Monday.

Securing the world’s water supply is one of the greatest challenges of our time. Research at Stockholm University is now presenting an alternative method for quantifying the global risk of water scarcity. Results indicate higher risks to water supply than previously expected if accounting for the environmental conditions and governability where rain is produced. Securing the…
Our sun drives a constant outward flow of plasma, or ionized gas, called the solar wind, which envelops our solar system. Outside of Earth’s protective magnetosphere, the fastest solar wind rushes by at speeds of over 310 miles (500 kilometers) per second. But researchers haven’t been able to figure out how the wind gets enough…
Moiré superlattices, structures that arise when two layers of two-dimensional (2D) materials are overlaid with a small twist angle, have been the focus of numerous physics studies. This is because they have recently been found to host novel fascinating unobserved physical phenomena and exotic phases of matter. Moiré superlattices, structures that arise when two layers of…
Zion National Park is home to a California condor, an endangered bird with a wingspan of more than 9 feet, that soars the same skies she shared with her brother before he died. Zion National Park is home to a California condor, an endangered bird with a wingspan of more than 9 feet, that soars the…
Yosemite National Park is famous for towering waterfalls, giant sequoia trees and massive granite cliffs. But at an out-of-the-way spot near the park’s western boundary few visitors ever see, a landmark of a different type is taking shape. Yosemite National Park is famous for towering waterfalls, giant sequoia trees and massive granite cliffs. But at an…
Over the last three decades, California has seen increasing erosion after major wildfires—a phenomenon that not only endangers water resources and ecosystems, but is also likely to worsen with climate change, according to researchers.

SpaceX got the OK to fly again from the Federal Aviation Administration and didn’t waste any time knocking out launches from both Florida and California early Saturday, but the crewed Polaris Dawn launch remains on hold because of weather.
