This study compared two commercial shower filters and three individual filtration media to evaluate their ability to reduce total residual chlorine under household flow conditions. By identifying which materials most effectively reduce chlorine during regular shower use, this research provides practical information for consumers and offers guidance for designing more affordable and reusable shower filtration systems.

Using machine learning to predict the risk of algae bloom

The authors looked at different treatments to clean up rainwater collected at home. They found that chlorine treatment and treatment with hydrogen peroxide catalyzed by yeast showed similar potential for cleaning up contaminated rainwater, but that further studies are needed to better assess impact on specific contaminant levels still present.

Here, in an effort to develop a model to predict future groundwater levels, the authors tested a tree-based automated artificial intelligence (AI) model against other methods. Through their analysis they found that groundwater levels in Texas aquifers are down significantly, and found that tree-based AI models most accurately predicted future levels.

The authors test the effect of caffeine on the behavior of the Siamese fighting fish Betta splendens.

The authors investigated the efficacy of functionalized graphene oxide nanoparticles for turning saltwater to freshwater.

The study explored converting Gracilaria seaweed waste—known for releasing toxic hydrogen sulfide when decomposed—into biochar as a sustainable solution for waste management and soil improvement.

The authors looked at the ability of Spirulina platensis to reduce contaminants in wastewater in order to develop a more accessible treatment option. They found that S platensis did reduce the concentration of pollutants present within simulated agricultural wastewater.

In this article, the authors investigate the shear modulus of different types of paper in the setting of the crumpling effect.

Previously established data indicate that cemeteries have contributed to groundwater and soil pollution, as embalming fluids can impact the microbiomes that exist in decomposing remains. In this study, Caputo et al hypothesized that microbial variation would be high between cemeteries from different eras due to dissimilarities between embalming techniques employed, and furthermore, that specific microbes would act as an indication for certain contaminants. Overall, they found that there is a variation in the microbiomes of the different eras’ cemeteries according to the concentrations of the phyla and their more specific taxa.
