NewsEngineered yeast gives the US a green edge in the critical minerals market
A new, U.S.-based, environmentally friendly method for mining rare-earth elements used in consumer electronics, clean energy, defense and biomedical imaging uses oxalic acid made by sugar-eating engineered yeast, extracting almost all the rare-earth elements from low-grade ore.

NewsWhen waste becomes fertilizer: Can sludge-derived liquids reshape aquatic life in farmlands?
Hydrothermal carbonization has been proposed as a soil amendment to reduce synthetic fertilizer inputs and enhance crop productivity. Research finds it reshapes community assembly, trophic interactions, and functional expression in periphyton, with network integrity emerging as the primary driver of ecosystem functioning.

NewsGrowing buildings in space: researchers test fungi as construction material for moon, Mars
A NASA-funded project will investigate whether certain fungi can be combined with regolith — loose rock and soil found on the surface of the moon and other planets — to create materials that could one day support construction in places other than Earth.

NewsFungi could transform leftovers into lifelines
A new paper outlines an ’emerging circular fungal biorefinery’ – a system in which low-value agricultural byproducts are converted through fungal fermentation into high-protein, nutrient-rich foods.

News How recycled sewage could make the moon or Mars suitable for growing crops
Scientists are investigating how a solution of recycled sewage interacts with simulated lunar and Martian regolith to see if the result provides a suitable medium to grow crops. Bioregenerative life support systems consist of a series of bioreactors and filters that transform sewage into a nutrient-dense solution.

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.

NewsFungus unlocks hidden phosphorus from massive industrial waste
Researchers have shown that Aspergillus niger can extract large amounts of residual phosphorus from phosphogypsum, a byproduct of phosphoric acid production that is generated in enormous quantities worldwide. More than 40 per cent of the phosphorus locked inside this waste material can be recovered.
