Biomass from microalgae

Biomass from microalgae: the potential of domestication towards sustainable biofactories SUMMARY: Microalgae could potentially be a renewable source of energy for people. Unfortunately, there are many issues right now with growing enough algae and keeping the process affordable (aka: it’s too expensive to grow and use algae commercially). The article is divided up into several… Continue reading Biomass from microalgae

Microgravity and the Respiratory System

Microgravity and the Respiratory System SUMMARY: What are the effects of gravity on lung function? This study first breaks down how gravity works and its effects on living organisms. The second section explains lung function with and without gravity. Finally, the last sections look at the difference in lung function during and after short and… Continue reading Microgravity and the Respiratory System

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

Using ciliates as indicators

Protozoa ciliates community structure in urban streams and their environmental use as indicators SUMMARY: Three urban stream samples were collected during both dry and rainy seasons in Brazil. Ciliates were classified and identified in each stream. The relationships between the ciliates, abiotic factors, and biotic factors are discussed in the last section of the paper.… Continue reading Using ciliates as indicators

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

Conservation of biodiversity to improve human well-being

Conservation of biodiversity as a strategy for improving human health and well-being SUMMARY: This article looks at the concept that increasing biodiversity in an ecosystem can decrease the prevalence of diseases. While the idea seems simple (more hosts for the disease, less incidences of the disease spreading to people), the issue is much more complicated.… Continue reading Conservation of biodiversity to improve human well-being
