The natural breakdown of some rocks sucks carbon dioxide out of the atmosphere. Knowing how quickly it happens could help scientists engineer solutions to the climate crisis.
Unraveling the Mystery of a Rare Mineral on Mars
The discovery of tridymite in Mars’s Gale Crater triggered debate about the rare mineral’s origins. A research team recently suggested a scenario with explosive implications.
Ocean Acidification May Drive Diatom Decline
Diatoms contribute to global oxygen production, marine food webs, and carbon sequestration, but scientists predict that diatom populations will decline due to ocean acidification associated with climate change.
Small Catchments Sustain Silicon Signatures Following Storms
Watersheds have unique patterns of silicon export due to differences in subsurface water routing and biogeochemical reactions.
Better Together: Perovskites Boost Silicon Solar Cell Efficiency
Scientists engineer a way to layer materials to boost efficiency without interrupting manufacturing processes.
State-of-the-Art Technology, Serendipity, and Secrets of Stonehenge
The first comprehensive analysis of what the sarsen stones are made of came about with new technology—and good old-fashioned luck.
New Recognition for Major Players in the Ocean’s Silicon Cycle
Tiny, shelled protists known as Rhizaria may be responsible for up to one fifth of the total amount of silica produced by the world’s oceanic organisms.
Crystals Connect Bubbles in Explosive Magmas
Hydrous silica-rich magmas can degas through connected bubble pathways when as little as 20% crystals are present, influencing transitions from explosive, Vulcanian-style eruptions to lava effusion.
The Tiny Organisms That Transport Silica Across Earth’s Oceans
Phaeodarians play a major role in marine nutrient cycle.
One of World’s Oldest Animals Records Ocean Climate Change
Researchers probe millennia-old deep-ocean sponges for links between ocean nutrients and climate.
