Explaining long-standing mysteries about Earth's formation and evolution

Earth’s mantle is the thick layer of silicate rock between Earth’s crust and its molten core. It makes up about 84% of our planet’s volume.

Rapid warming in the Gulf of Maine reverses 900 years of cooling

Rapid 20th century warming in the Gulf of Maine has reversed long-term cooling that occurred there during the previous 900 years, according to new research that combines an examination of shells from long-lived ocean quahogs and climate model simulations.

Volcanic super eruptions are millions of years in the making -- followed by swift surge

Researchers have discovered that super-eruptions occur when huge accumulations of magma deep in the Earth's crust, formed over millions of years, move rapidly to the surface disrupting pre-existing rock.

The many versions of a female scientist

Depictions of women in science, technology, engineering and mathematics (STEM) are powerful sources of inspiration for young women who aspire to a career in those fields. But stereotypes of female scientists persist, and we have some way to go to vanquish them, say the authors...

This microlab is helping Stanford researchers figure out where to store carbon dioxide

Scientists at Stanford University have developed a new solution for the challenge of making sure that when carbon dioxide (CO2) is injected underground, it actually stays put.For decades, climate models have predicted that...

We may finally understand how a strange, rare mineral on Mars came to exist

In 2016, the Curiosity rover came across something really peculiar in Gale Crater on Mars. On the slope of Mount Sharp, where Curiosity labored, were large quantities of a rare mineral; rare, at least, here on Earth. Tridymite, a...

Climate-driven rainfall impacts in the Sudd wetland may be a monstrous methane feedback loop.

Scientists at the University of Edinburg believe they have found the reason for a spike in methane from saturated soils - that microbes feed on. NOAA has found that for the years 2020 and 2021, the atmospheric methane had exploded since 1983, when measurements began.

Wood heating pollutes the air in mountain areas more than previously assumed

Around 30 million people in Europe live in mountain valleys. A large part of this population is more affected by air pollution than previously assumed. This is the conclusion of a Slovenian-German research team from measurements...
