Gases from hot springs in central Zambia show signs of mantle fluids rising to the surface, suggesting an early-stage continental rift. Researchers say this could mark the start of a new tectonic plate boundary. The findings come from samples collected in the Kafue Rift.

A team of scientists has identified a long-hidden underground formation beneath the United States dating back to the Jurassic period. The structure, described as a lost basement, may intensify the effects of future solar storms on the power grid.

Researchers from New York University Abu Dhabi have uncovered evidence that water flowed beneath Mars' surface billions of years ago, potentially sustaining habitable conditions longer than previously thought. Analysis of ancient sand dunes in Gale Crater, studied by NASA's Curiosity rover, shows minerals left by groundwater. These findings suggest subsurface environments could have protected microbial life after surface water vanished.

Researchers at Curtin University have developed a technique using krypton gas in microscopic zircon crystals to track the history of Earth's landscapes over millions of years. The method, which relies on cosmic rays striking surface minerals, reveals how erosion and sediment movement have shaped terrains in response to climate and tectonic changes. This approach could also aid in locating mineral deposits in Australia.

A recent analysis of clay pebbles from Mars' Jezero crater suggests the planet experienced a warm and wet climate during the Noachian epoch billions of years ago. This finding challenges the prevailing view of a cold and icy environment at that time. The evidence comes from NASA's Perseverance rover and points to conditions potentially suitable for life.

Simulations indicate that two massive hot rock blobs near Earth's core have played a role in generating and shaping its magnetic field, making it irregular over millions of years. Researchers analyzed ancient volcanic rocks and ran models to reach this conclusion. The findings suggest these blobs created uneven heat flow that affected the field's symmetry.
