NewsNameko mucilage: An eco-friendly solution for microplastic pollution
Researchers use natural mucilage from nameko mushrooms for the removal of micro- and nano-plastics from water. The mucilage is rich in polysaccharides, particularly pectin—a naturally occurring plant-based compound—which is known for its particle-binding properties.

NewsScientists discover ‘consortium’ of bacteria cooperating to eat phthalate plasticizers that single microbes can’t stomach
Researchers have discovered a synergistic ‘consortium’ of plastic-eating bacteria, which can eat phthalate esters (PAEs) – plasticizers which are often found in building materials, food packages, and personal care products, but have been implicated in hormonal, metabolic, and developmental disorders and some cancers.

NewsPig farm ammonia pollution may indirectly accelerate climate warming, new study finds
A new study shows that ammonia released from intensive livestock farms can significantly increase nearby soil emissions of nitrous oxide, a powerful greenhouse gas that contributes to climate change and ozone depletion.

NewsThe new ‘forever’ contaminant? Study raises alarm on marine fiberglass pollution
Researchers investigating fibreglass contamination of an estuary looked at the biofilm and the deeper sediment layer where sediment‑dwelling invertebrates live and feed. They found fibreglass particles at several of the surface biofilm testing sites and 96 per cent of the sediment testing sites.

NewsSelf-repairing biohybrid system uses sunlight to purify uranium-contaminated water
The efficiency of microbial remediation technologies is often limited by the slow electron transfer rate of microorganisms themselves. Scientists have successfully constructed a novel, self-regenerating “bacteria-mineral” biohybrid system that can utilize light like a solar cell, greatly enhancing the purification efficiency of uranium pollution.

NewsMineral dust accelerating melting of Greenland ice sheet
Scientists have found that airborne mineral dust and other aerosols are directly connected to how much algae grows on the ice. The algae interfere with albedo, or the reflection of the sun’s rays, exacerbating melting.
