Anhydrobiosis without trehalose in bdelloid rotifers

Anhydrobiosis without trehalose in bdelloid rotifers SUMMARY: There are many types of organisms that can dry out, rehydrate, and then go about their lives with no problems. Many of the larger ones use trehalose or sucrose as an antifreeze. Bdelloid rotifers (tiny microscopic animals) do not. This study looked at the carbohydrate content in desiccated… Continue reading Anhydrobiosis without trehalose in bdelloid rotifers

Enzyme Catalysis To Power Micro/Nanomachines

Enzyme Catalysis To Power Micro/Nanomachines SUMMARY: Is it possible to make nanomachines out of enzymes? This review looks at the ways we can harness enzymes to self-propel or use them as tiny machines. Doing so would have many implications in nanotechnology and drug delivery. There were a few ways to use enzymes. First, there was… Continue reading Enzyme Catalysis To Power Micro/Nanomachines

Genetic diversity of Entamoeba in cockroaches

Genetic diversity of Entamoeba: Novel ribosomal lineages from cockroaches SUMMARY: Researchers in this study looked at the diversity of Entamoeba in 3 different species of cockroaches (the American roach, the Dubia roach, and the Madagascar hissing roach) by looking at SSU rDNA in the ground up intestines of the cockroaches. They found that the Entamoebas… Continue reading Genetic diversity of Entamoeba in cockroaches

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers SUMMARY: This article talked about using soil eutardigrades and bdelloid rotifer primers to quickly and easily identify these organisms directly. Due to the fact that there are so many types of microorganisms in soil, many of which are still unidentified and unable to be cultured in… Continue reading Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression in a mouse via the vagus nerve SUMMARY: This study looked at the effect of Lactobacillus rhamnosus on GABA receptors in the brain as well as the role of the vagus nerve in communicating between the gut and the brain. Results showed that… Continue reading Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

Variation in the human immune system is largely driven by non-heritable influences

Variation in the human immune system is largely driven by non-heritable influences SUMMARY: This study was a twin study (identical twin). The researchers looked at different elements of the immune system: T-cells, NK cells, B-cells, cytokines, etc. and saw that the development of these cells were influenced by non-heritable factors such as the environment and… Continue reading Variation in the human immune system is largely driven by non-heritable influences
