Field and lab conditions alter microbial enzyme and biomass dynamics

Field and lab conditions alter microbial enzyme and biomass dynamics driving decomposition of the same leaf litter SUMMARY: This study looked at the rate of decay between litter in lab conditions and natural conditions. They used fallen leaves from dogwood trees, oak trees, maple trees, and maple-oak tree mix. Results showed quite a difference in… Continue reading Field and lab conditions alter microbial enzyme and biomass dynamics

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

Environmental impacts on the diversity of methane-cycling microbes and their resultant function

Environmental impacts on the diversity of methane-cycling microbes and their resultant function SUMMARY: There are two types of microbes that are involved in methane cycling: ones that produce methane (methanogens) and ones that use methane as a source of energy and convert it to carbon dioxide (methanotrophs). This article review looked at all the different… Continue reading Environmental impacts on the diversity of methane-cycling microbes and their resultant function

Beaming Purines

The Formation of Nucleobases from the Ultraviolet Photoirradiation of Purine in Simple Astrophysical Ice Analogues SUMMARY: Purines were combined with water and ammonia and beamed with UV photons similar to the pyrimidines in “Beaming Pyrimidines Part 1”. Researchers found many purine compounds in the products including adenine and guanine (at different concentration levels). The discussion… Continue reading Beaming Purines

Beaming Pyrimidines Part 5

Mechanisms for the formation of thymine under astrophysical conditions and implications for the origin of life SUMMARY: This article talks about different ways thymine can form under the conditions given in Part 4 of the Beaming Pyrimidines series. By adding hydroxyl and methyl groups to pyrimidine and beaming the mixture, thymine can form. The role… Continue reading Beaming Pyrimidines Part 5

Beaming Pyrimidines Part 4

The Photochemistry of Pyrimidine in Realistic Astrophysical Ices and the Production of Nucleobases SUMMARY: To mimic the conditions on a comet or space clouds, the gas mixture beamed in this experiment was a mixture of: water, methanol, ammonia, methane, and pyrazine. Pyrazine is an isomer of pyrimidine (both have the chemical formula C4H4N2). This mixture… Continue reading Beaming Pyrimidines Part 4
