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

Relationship between the flagellates and the ciliates

Relationship between the flagellates and the ciliates SUMMARY: This is an article comparing the structural and genomic differences between ciliates and flagellates. Dinoflagellates seem to be the ancestors of ciliates based on similarities in various cell structures and rRNA sequencing. Structures compared in this article include: mitochondria, mechanisms of cilia and flagella, nucleus, and how… Continue reading Relationship between the flagellates and the ciliates

Meiotic Genes in Colpodean Ciliates Support Secretive Sexuality

Meiotic Genes in Colpodean Ciliates Support Secretive Sexuality SUMMARY: Researchers compared the genomes of two ciliates: one known to have sex, and another that has not been observed to have sex under laboratory conditions. Genes for meiosis were found in both classes of ciliates. Also, structures such as the micronuclei and macronuclei indicate that perhaps… Continue reading Meiotic Genes in Colpodean Ciliates Support Secretive Sexuality

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

The evolution of diatoms and their biogeochemical functions

The evolution of diatoms and their biogeochemical functions SUMMARY: This article talks about the evolution, cell structure, and ecological role of diatoms. The first section is an introduction to what diatoms are. The second section talks about the evolution of photosynthesis (from cyanobacteria to eukaryotes with chloroplast). The third section explains the significance of the… Continue reading The evolution of diatoms and their biogeochemical functions

Serotonin as a link between the gut-brain-microbiome axis in autism spectrum disorders

Serotonin as a link between the gut-brain-microbiome axis in autism spectrum disorders SUMMARY: This paper reviews the studies looking at the connection between serotonin production, microbiome, and autism. The first two sections give some basic information on serotonin, its reuptake transporter, and the gut-brain connection. Sections three and four talk about changes in serotonin (either… Continue reading Serotonin as a link between the gut-brain-microbiome axis in autism spectrum disorders
