Mitochondrial respiration during sepsis

Variability of mitochondrial respiration in relation to sepsis-induced multiple organ dysfunction SUMMARY: This is an article review on how oxygen is used by the mitochondrion during sepsis. The role of mitochondria play during sepsis is still inconsistent, despite the various studies that have been done. There are three hypotheses for mitochondrial dysfunction. 1. Mitochondria are… Continue reading Mitochondrial respiration during sepsis

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

Powered by Light

Powered by Light: phototrophy and photosynthesis in prokaryotes and its evolution SUMMARY: This article looks at the still-not-yet-fully-known evolution and history of photosynthesis. There were various types of photosynthesis, the main difference being the type of electron donor. Some organisms used water as an electron donor, while others used things like hydrogen and manganese. The… Continue reading Powered by Light

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

De novo origins of multicellularity in response to predation

De novo origins of multicellularity in response to predation SUMMARY: Chlamydomonas are common, single-celled green algae that are flagellated and can move around. They’re a strange cross between plants and protists. In this study, scientists subjected chlamydomonas to predation by paramecia (common freshwater ciliates) and observed that after about 750 generations, the chlamydomonas took on… Continue reading De novo origins of multicellularity in response to predation
