River erosion can shape fish evolution

Metamorphosed banded iron formation from southern Wyoming showing deformation and folding. The rock is approximately 2.7 billion years old. Dark bands are iron oxides (magnetite, hematite) and yellow-orange bands are chert with iron oxide inclusions (jasper). (Photo by Linda Welzenbach-Fries/Rice University)

Iron-rich rocks unlock new insights into Earth’s planetary history

A microscope image from an experiment conducted for this study. The image contains glass (brown), large garnets (pink) and other small mineral crystals. The field of view is 410 microns wide, about size of a sugar crystal. Credit: Science (2023). DOI: 10.1126/science.ade3418

Study presents new clues about the rise of Earth’s continents

An illustration showing how some Earth’s signature features, such as its abundance of water and its overall oxidized state could potentially be attributable to interactions between the molecular hydrogen atmospheres and magma oceans on the planetary embryos that comprised Earth’s formative years.
