科学者チームが、米国の地下深くに長年隠されていたジュラ紀に遡る地質構造を特定した。この「失われた基盤」と呼ばれる構造が、将来の太陽嵐が送電網に与える影響を増幅させる可能性がある。
研究者らは、近年の地質学的分析を通じてこの構造を特定した。2026年5月9日に報告された調査結果によると、この構造は地下深くに位置しており、ジュラ紀に由来するものだという。

The Chicxulub asteroid impact that ended the dinosaur era left the site in what is now Mexico hot enough to sustain underground microbial life for at least 8 million years. New analysis of rock cores shows the hydrothermal system lasted far longer than earlier estimates suggested.

Researchers have mapped a massive fan-shaped network of basins beneath the East Antarctic Ice Sheet, linking several previously studied features into one large geological structure. The discovery, published in a 2026 study, offers new insights into the continent's tectonic past and its influence on current ice movement.
Researchers have traced the origins of diverse early space rocks to a dust trap just outside Jupiter's orbit. The findings come from computer simulations matching meteorite compositions found on Earth. They suggest this region produced multiple generations of planetesimals over millions of years.

A massive body of magma surged upward beneath São Jorge Island in Portugal's Azores archipelago in March 2022, triggering thousands of earthquakes before stalling underground. The event, detailed in a new study, represented a failed eruption that raised but ultimately eased fears of volcanic activity.
Scientists have determined that structures once seen as traces of tiny animals in 540-million-year-old Brazilian rocks are actually fossilized communities of bacteria and algae. The reexamination uses advanced imaging to reveal preserved cells and organic material.
