Excessive use of fertilizers has fueled global food production, but it has also left behind a serious problem: nitrate pollution in soil and water. High nitrate levels threaten drinking water safety, aquatic ecosystems, and public health. Now, a new review published in Biochar highlights how biochar, a carbon-rich material made by heating plant or waste biomass, could provide an effective, low-cost, and sustainable solution.

When it comes to clean energy, solar and wind often dominate the headlines. But in the lush, river-rich landscapes of Southeast Asia, another renewable powerhouse is quietly making waves—hydropower. A major new study published on August 4, 2025, in Carbon Research proves that hydropower isn’t just a side player in the region’s energy mix—it’s a leading force in cutting carbon emissions, with the potential to reshape the future of sustainable development.

Proper maintenance of underground infrastructure is crucial for a city’s sustainable development. However, with its high-density underground utilities, such maintenance work is particularly challenging in Hong Kong. A research team from The Hong Kong Polytechnic University (PolyU) has leveraged advanced underground exploration technologies to develop underground utilities inspection systems that support early detection of urban infrastructure anomalies, including voids and pipe leakages, for enhanced urban management.

Potato tuber dormancy and sprouting are pivotal to crop yield, storage, and market value. 

Aging brain shows deterioration of blood-brain barrier (BBB), but the underlying mechanisms are unclear. Guo et al, from Massachusetts General Hospital, reported that the effects of astrocytes on endothelial cell permeability depend on the “age” of astrocytes, and increased angiotensinogen expression in senescent astrocytes may be one of the mediators. These data suggest the importance of cell-cell interaction in neurovascular unit, and point towards a potential therapeutic approach to rescue BBB in aging brain.

Phospholipids, essential components of cell membranes, are increasingly recognized for their active roles in regulating innate immunity and inflammation. A new review is published to outline how phospholipid metabolism shapes immune cell behavior, influences the outcome of host defense and tissue homeostasis. The authors also discuss how dysregulation of phospholipid metabolism contributes to inflammatory diseases, such as autoimmune diseases, cardiovascular diseases and cancers, and highlight the potential strategies of restoring phospholipid homeostasis for disease treatment.

A new review published in Environmental and Biogeochemical Processes reveals how tiny iron oxyhydroxide nanoparticles, among the most abundant nanoparticles in soils and water, form and interact with metals, organic matter, and microbes, profoundly shaping Earth’s environment.

Scientists have unveiled a pioneering method that could help farmers reclaim lands blighted by toxic metals and boost the safety of crops grown in contaminated soils. The study, led by a research team in China, reveals that phosphorus-modified biochar, a carbon-rich material derived from apple tree branches, can dramatically reduce the threat posed by heavy metals in agricultural soils near mining areas.

You might think adding crop straw to soil is a no-brainer: it enriches the earth, boosts organic matter, and supports sustainable farming. But what if the weather could turn this green practice into a hidden risk for heavy metal pollution? A groundbreaking new study, published on August 1, 2025, in Carbon Research—has uncovered the complex, climate-driven dance between straw incorporation, soil organic matter, and lead (Pb) mobility. And the results are reshaping how we think about safe soil remediation in a changing climate. Led by Dr. Song Cui from the International Joint Research Center for Persistent Toxic Substances (IJRC-PTS) and Research Center for Eco-Environment Protection of Songhua River Basin, Northeast Agricultural University, Harbin, China, in collaboration with Dr. Yongzhen Ding from the Agro-Environmental Protection Institute, Ministry of Agriculture and Rural Affairs, Tianjin, China, this research dives deep into the invisible world of dissolved organic matter (DOM)—and how it can either lock away or unleash toxic metals.

In order to efficiently dehydrogenate propane to propene over CoO_x/Silicalite-1, supported CoO_x species no larger than 2 nm should be reduced in situ to metallic Co⁰ and then become decorated with carbon deposits.
