The force of a volcanic eruption is closely tied to how many gas bubbles appear within rising magma, as well as the timing of their formation. For many years, scientists believed that most bubbles developed only when magma ascended and the surrounding pressure fell. In deeper layers, high pressure keeps gases dissolved in the molten…

Earthquake faults located deep within the planet can reconnect after a seismic disturbance, according to new research from the University of California, Davis. The study, published Nov. 19 in Science Advances and supported by National Science Foundation grants, introduces a new factor that could reshape how scientists interpret fault behavior linked to major earthquakes. “We…

Around 115 million years ago, the waters north of Australia supported a massive shark that can be viewed as an early relative of the creatures made famous by “Jaws.” Newly examined fossils show that modern sharks began developing extremely large body sizes far earlier in their evolutionary timeline than scientists once thought. These remains indicate…

Scientists have known for many years that hormones can shape how the brain works, affecting emotions, mental energy, and everyday choices. What remains unclear is exactly how these chemical signals bring about such changes. A recent investigation offers new insight by examining the role of estrogen, a hormone central to the female reproductive cycle. Through…
