(Press-News.org) Scientists are highlighting biochar, a carbon-rich material produced from biomass, as a promising solution to help soils store carbon and reduce greenhouse gas emissions, offering new hope in global climate mitigation efforts.
In a new comprehensive review, researchers synthesized current knowledge on how biochar improves soil carbon storage, reduces greenhouse gases, and provides practical frameworks to measure its climate benefits. The findings demonstrate that biochar could play a crucial role in transforming soils into long-term carbon sinks, supporting agricultural sustainability and carbon neutrality goals.
Biochar is created by heating organic biomass such as crop residues, wood, or agricultural waste in low-oxygen conditions. This process converts unstable organic carbon into a stable form that can persist in soil for hundreds to thousands of years. According to the study, biochar not only stores carbon directly but also protects existing soil organic carbon from decomposition, creating a dual carbon sequestration effect.
“Our analysis shows that biochar can simultaneously lock carbon into soils and regulate microbial processes that reduce greenhouse gas emissions,” said the study’s corresponding author. “This dual function makes biochar a unique and scalable tool for achieving soil carbon neutrality.”
The review reveals that biochar improves carbon storage through several interconnected mechanisms. Its highly porous structure physically shields soil organic carbon from microbial breakdown while also promoting the formation of soil aggregates that stabilize carbon. In addition, biochar can stimulate what scientists call a negative priming effect, meaning it slows the decomposition of native soil carbon, further enhancing carbon retention.
Beyond carbon storage, biochar also helps reduce emissions of nitrous oxide and methane, two potent greenhouse gases produced by soil microbial activity. The researchers found that biochar alters soil chemistry, microbial communities, and redox processes, encouraging microbial pathways that convert harmful greenhouse gases into less harmful forms.
“Biochar functions like an electron shuttle in soil,” explained the researchers. “It helps regulate microbial reactions that convert nitrous oxide into harmless nitrogen gas, significantly lowering greenhouse gas emissions.”
However, the effectiveness of biochar depends strongly on how it is produced and applied. Factors such as feedstock type, pyrolysis temperature, soil characteristics, and application rate all influence biochar’s performance. For example, biochar produced at higher temperatures typically has greater stability and carbon sequestration potential, while matching biochar properties to specific soil conditions can maximize environmental benefits.
The study also emphasizes the importance of accurately measuring biochar’s climate impact. The authors evaluated multiple carbon accounting approaches, including isotope tracing methods to measure soil carbon changes and life cycle assessments that track emissions across production and application stages. These integrated frameworks are essential for verifying carbon neutrality claims and supporting carbon credit systems.
Large-scale field studies show encouraging results. Biochar applications have been linked to increased soil organic carbon, improved crop yields, and significant reductions in greenhouse gas emissions. The review suggests that optimized biochar deployment could provide both environmental and economic benefits, including reduced fertilizer use and potential revenue from carbon markets.
Despite its promise, the researchers highlight remaining challenges. Long-term field studies are needed to better understand biochar aging, soil interactions, and large-scale implementation strategies. The authors also suggest that advanced engineered biochar materials could further enhance carbon storage while simultaneously remediating soil pollutants.
“Our findings demonstrate that biochar has moved beyond a theoretical concept and is becoming a practical tool for climate-smart agriculture,” the authors said. “With proper optimization and verification, biochar could become a cornerstone technology for sustainable soil management and global carbon neutrality.”

Tiny cell messengers show big promise for safer protein and gene delivery
2026-02-13
Ikoma, Japan—
Extracellular vesicles (EVs) are tiny membrane-bound particles released by cells to transport proteins and other molecules to neighboring cells. Because of this natural delivery ability, EVs have attracted growing interest as potential vehicles for therapeutic protein and genome-editing enzyme delivery. However, EVs can originate either from intracellular endosomal compartments or directly from specialized protrusions on the cell surface, and until now, it has remained unclear which EV type is more effective at delivering functional protein cargo.
To address this question, researchers in ...
AMS releases statement regarding the decision to rescind EPA’s 2009 Endangerment Finding

The American Meteorological Society has released the following Rapid Response Statement in response to the repeal of the EPA’s 2009 Endangerment Finding.
A Response to the Decision to Rescind EPA’s 2009 Endangerment Finding
The American Meteorological Society (AMS) is deeply concerned by the repeal of EPA’s 2009 Endangerment Finding, which correctly concluded that greenhouse gas emissions harm health and well-being for current and future generations.
AMS reaffirms key scientific conclusions of climate change that relate to the Endangerment Finding:

Parents’ alcohol and drug use influences their children’s consumption, research shows
2026-02-13
“Like father, like son? Can parenting styles break the intergenerational pattern of alcohol and drug use?” A group of Brazilian researchers analyzed data on the behavior of 4,280 adolescents and their guardians based on this question, arriving at two important conclusions.
Yes, parental attitudes are one of the most relevant factors in preventing alcohol and drug use among young people. However, the way guardians educate their children can significantly mitigate the risk, even in families where caregivers use these substances, including cigarettes, vapes (which are banned in Brazil), and marijuana.
The reduction in risk is more significant when the relationship ...

Deforestation in the Amazon raises the surface temperature by 3 °C during the dry season
2026-02-13
Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface temperature, a decrease in evapotranspiration, and a reduction in precipitation during the dry season and in the number of rainy days.
The results are part of a study based on satellite data published in late November in the journal Communications Earth & Environment.
The study points out that highly deforested regions (with forest cover below 60%) share climatic similarities with areas of transition between rainforest ...

Sour grapes? Taste, experience of sour foods depends on individual consumer
2026-02-13
UNIVERSITY PARK, Pa. — Biting into a tart green apple is a different taste and sensory experience than sucking juice from a lemon — and both significantly vary from accidentally consuming spoiled milk. Each of these foods contains a different organic acid that gives rise to the flavor commonly referred to as “sour,” even when the taste and related mouthfeel sensations such as puckering and drying vary drastically from food to food and person to person. Now, Penn State researchers have found that while some of that difference comes from individual perceptions, the acids themselves vary in sourness, even at the same concentrations.
The researchers, ...
