Researchers have demonstrated prototype windows that switch from reflective to clear with the simple addition of a liquid. The new switchable windows are easy to manufacture and could one day keep parked cars cool in the sun or make office buildings more energy efficient.
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet). It's also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink. New research published on Dec. 14 in Nature and led by the University of Texas at Austin and the University of South Florida found that the East Antarctic Ice Sheet may not be as stable as it seems.
It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new Rutgers University-New Brunswick-led analysis. The study is the first to link global and local sea-level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet.
In a new study led by Dr. Danilo Di Genova, from the University of Bristol's School of Earth Sciences, an international team of scientists provide evidence, for the first time, that a subtle tipping point of the chemistry of magmas clearly separates effusive from explosive eruptions worldwide.
Geomagnetic disturbances from solar storms or electromagnetic pulse weapons pose a high risk to the electrical power grid. This project examines a real-world example of 3-D mapping of the crust and mantle in the northwestern US from EarthScope data to determine risks posed by ground conductivity that could amplify or change how geomagnetic disturbances affect power lines. This new 3-D method detected surprising effects that the current 1-D method of risk assessment fails to detect.
Researchers at the University of Pittsburgh, Pennsylvania have created glass that lets through a large amount of light while appearing hazy, a combination of properties that could help boost the performance of solar cells and LEDs.
Why do the Andes exist? Why is it not a place of lowlands or narrow seas? Wouter Schellart, a geophysicist at the Vrije Universiteit Amsterdam, has been pondering these questions for more than a decade. Now, he has found the answers using an advanced computer model. 'It's a matter of enormous size, longevity and great depth,' he said. 'These aspects made the Andes the longest and second highest mountain belt in the world.'
The strong atmospheric pressure of hurricanes also generates detectable seismic waves. Using seismic waves to track hurricanes might provide a new tool for monitoring hurricanes from a distance.
Kyushu University (Japan) researchers analyzed high-resolution seismic velocity data from 36 seismograph stations across the island of Kyushu to identify variations before, during, and after the MW 7.0 2016 Kumamoto earthquake. Velocity decreased in the region of the rupture fault when the earthquake struck, and then gradually recovered, although this recovery showed spatial variability. This variability corresponded to aftershock concentration and volcanic activity. The findings may be useful for disaster prediction and preparedness.
Scientists have found the halogen levels in the meteorites that formed the Earth billions of years ago are much lower than previously thought.
