Divergent Mechanisms of Rhizosphere and Non-Rhizosphere Soil Organic Carbon Sequestration Under Precipitation Variability: Evidence from Microbial Life-History Strategies

Divergent mechanisms of rhizosphere and non-rhizosphere soil organic carbon sequestration under precipitation variability: Evidence from microbial life-history strategies Abstract Background: Climate change-induced precipitation variability has profound impacts on soil carbon dynamics in agricultural ecosystems in arid regions. Methods: To elucidate the carbon retention mechanisms of rhizosphere and non-rhizosphere soils under precipitation variability, we conducted an … Read more

3D Printed Living Materials: A Solution for Carbon Dioxide Absorption in Construction

Scientists are combining traditional materials with bacteria, algae, and fungi to create bio-materials that can acquire practical properties through microbial metabolism. “For example, the ability to absorb carbon dioxide from the air through photosynthesis,” says Mark Tibbitt, a professor of macromolecular engineering at ETH Zurich. Currently, the interdisciplinary team led by Tibbitt has turned this … Read more

The Myth of DAC Shattered! The Cost Reduction Logic of Photovoltaic Cells Does Not Apply to Direct Air Capture, Physical Limits Prevent Dramatic Cost Drops

In recent years, the astonishing drop in costs of photovoltaic (PV) and lithium batteries has sparked strong expectations in the climate policy and investment communities. Many hope that “Direct Air Capture” (DAC) technology can follow a similar trajectory of cost reduction. However, this analogy overlooks the fundamental differences in physical realities and market structures, necessitating … Read more
