The making of natural iron sulfide nanoparticles in a hot vent snail

https://www.pnas.org/content/116/41/20376 SUMMARY: The scaly-foot snail also known as Chrysomallon squamiferum is unique in that it makes iron sulfide nanoparticles. Chemically, most creatures who are only able to make minerals (biomineralization) using oxygen. The scaly-foot snail is able to do this in the absence of oxygen, a method that scientists are keen on understanding as it… Continue reading The making of natural iron sulfide nanoparticles in a hot vent snail

Rotifers Paralyzing Schistosomes

A rotifer-derived paralytic compound prevents transmission of schistosomiasis to a mammalian host SUMMARY: Researchers discovered that a new molecule produced by the rotifer, Rotaria rotatoria, paralyzes cercariae. Cercariae are the free-living/infectious stage of the flatworm Schistosoma, the cause of schistosomiasis. R. rotatoria live on the shell of freshwater snails and secrete a compound scientists have… Continue reading Rotifers Paralyzing Schistosomes

A Review of Microbial Biosorbents

A New Strategy for Heavy Metal Polluted Environments: A Review of Microbial Biosorbents SUMMARY: Heavy metal pollution is a serious environmental problem and the chemical/physical means of getting rid of them are either too expensive, not effective for low quantities of pollutants, or produce a lot of toxic waste. One solution is to use microbes… Continue reading A Review of Microbial Biosorbents

Impacts of Biogeochemical Redox Processes

Biogeochemical Redox Processes and their Impact on Contaminant Dynamics SUMMARY: Reduction and oxidation reactions are the drivers behind many biological processes. Energy is both stored and transferred through these reactions. This article talks about the various redox reactions that can occur, both biotically and abiotically, and how that affects both biogeochemical cycles and contaminants. The… Continue reading Impacts of Biogeochemical Redox Processes

Altered gut microbiota in Autistic Chinese children

Altered gut microbiota and short chain fatty acids in Chinese children with autism spectrum disorder SUMMARY: After looking at the fecal samples of 30 autistic children and 20 neurotypical children, researchers found that the autistic group had more instances of constipation, higher valeric acid (a type of short chain fatty acid), lower butyric acid, and… Continue reading Altered gut microbiota in Autistic Chinese children
