A new spin behavior has been found in the light-induced electron emission of tungsten ditelluride.
Through global-scale seismic imaging of Earth’s interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published today in Science Advances.
Seen only in isolated patches previously, the latest data suggests this layer of ancient ocean floor may cover the core-mantle boundary. Subducted underground long ago as the Earth’s plates shifted, this ultra-low velocity zone, or ULVZ, is denser than the rest of the deep mantle, slowing seismic waves reverberating beneath the surface.
“Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought,” said Dr. Samantha Hansen, the George Lindahl III Endowed Professor in geological sciences at UA and lead author of the study. “Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet.”
The concept for the CARAPACE yacht is sent straight from the future.
The 78m vessel has been conceptualized to double as a submarine that can dive to 985 feet.
Elena Nappi, an Italian based naval architect, has dreamed up this futuristic vessel.
The hybrid is designed for cruising the high seas and exploring the underwater world with its marine capabilities.
Scientists believe they may have found the secret to living past the age of 100. To some, the thought of living into your hundreds is a dream, while for others, it’s the complete opposite. But it seems that 70 percent of American adults actually want to live to 100, a 2022 poll by Edward Jones and Age Wave of 11,000 people revealed.

China and Brazil have struck a deal to trade in their local currencies instead of the US dollar. They joined a long list of countries including Saudi Arabia, Kenya and India. Why is the world attempting to de-dollarise? Palki Sharma decodes.
