Six research teams win Carbon Hub funding

Rice University's Carbon Hub has awarded seed grants to six research projects aiming to transform the oil and gas sector into a leading provider of clean hydrogen energy and solid carbon products. The selected teams will investigate various applications, including cement reinforced with carbon fibers, urban smog reduction, and replacin...

Measuring carbon nanotubes taken up by plants

Researchers developed a way to measure levels of specific carbon nanotubes in plant tissues using programmed thermal analysis. This method can detect small amounts of carbon nanotubes in leaves, stems, and roots, providing crucial insights into their environmental fate and potential human exposure.

Earth's terrestrial ecosystems may transition from carbon sinks to carbon sources within decades

The study suggests that up to half of land ecosystems could reach a tipping point where they release more carbon than they absorb by 2100 under a business-as-usual emissions scenario. Biomes with high carbon storage, such as rainforests and Taiga forests, may lose over 45% of their carbon sink capabilities by midcentury.

Faster, greener way of producing carbon spheres

Researchers at Swansea University have developed a faster, greener way to produce porous carbon spheres, which are crucial for carbon capture technology and renewable energy storage. The new method produces spheres with high carbon capture capacity and works effectively at large scales.

Oceans without oxygen

Researchers have discovered that ocean anoxic zones, which lack dissolved oxygen, are teeming with life and play a crucial role in the Earth's carbon cycle. The study found that microbes can still eat organic carbon but respiring sulfate, known as cryptic sulfur cycling, leading to more organic carbon deposits in sediments.

Bacteria in iron-deficient environments process carbon sources selectively

Researchers at Northwestern University found that bacteria in low-iron environments reroute their metabolic pathways to favor producing iron-scavenging compounds. This study provides insights into the impact of iron on carbon cycling in bacterial cells, with implications for ecosystem health and environmental biotechnology.

Lessons from a cooling climate

A team of researchers has applied their model to the emergence of Southeast Asia, finding that volcanic rock provinces in the tropics are a major factor in determining CO2 levels. This discovery sheds light on our current climate crisis and provides insights into how geological processes can help mitigate its effects.

North American cold-climate forests are already absorbing less carbon, study shows

A new study reveals that cold-climate forests at high latitudes are already absorbing less carbon, casting uncertainty on their ability to continue doing so. In contrast, Siberian forests have increased their carbon uptake four times more than other North American forests, suggesting stark divergent responses across regions.

Solving the jigsaw puzzle of regional carbon budgets

A new study has provided the first global 'bottom-up' terrestrial carbon budget, estimating a net sink of -2.2 ± 0.6 Pg C y-1 between 2000 and 2009. The study reveals that a significant portion of carbon fixed in terrestrial ecosystems is lost through fires, emissions, and export to rivers, rather than being retained in the soil.

The best things come in small packages

A miniaturized carbon dioxide monitoring instrument based on non-dispersive infrared technology has been developed to observe carbon dioxide concentrations in the boundary layer. The instrument provided consistent results with conventional gas chromatography analyzers and revealed that CO2 concentration decreases with increasing altitude.
