Turning crop waste into precision weapons against waterborne pathogens

Researchers have developed a novel class of biomass-derived carbon dots that selectively eradicate Staphylococcus aureus in water. The nanomaterials preferentially bind to pathogen-specific cell wall components, triggering localized oxidative stress and membrane damage while sparing non-target bacteria. This approach offers a sustainab...

Antibiotics in sediments may quietly boost greenhouse gas emissions

The study reveals that SMX enhances nitrous oxide emissions, which are nearly 300 times more potent than carbon dioxide. This increase occurs due to the suppression of nitrogen removal and stimulation of incomplete denitrification in sediments, leading to a significant impact on coastal ecosystems.

Peptide hormones and bile acids shaping immune tolerance of the liver: implications and applications

The liver's unique immune tolerance is driven by peptide hormones and bile acids, which activate anti-inflammatory responses and foster a tolerogenic phenotype in resident immune cells. This mechanism may explain the liver's reduced rates of transplant rejection but also poses challenges for treating liver infections.
