FOR IMMEDIATE RELEASE Contact: Diana Kenney, Marine Biological Laboratory 508-289-7139; dkenney@mbl.edu WOODS HOLE, Mass.— Proteomics, the study of large groups of proteins, can enhance our understanding of a wide range of organisms, with applications in medicine and developmental biology. Such analyses traditionally require a complete genome for the organism being studied in order to obtain […]

@MBL: Renewing the Joy of Discovery in the Embryology Course

Male stolon (ventral view, anterior up) of the annelid, Proceraea sp., fluorescently stained for acetylated tubulin (green), serotonin (yellow), F-actin (red; phalloidin), and nuclei (blue; DAPI).  Confocal z-stacks were viewed as maximum  projections and tiled together to cover the entirety of the animal (body length approximately 7.5 mm).

New Analysis Reveals Previously “Hidden Diversity” of Mouth Bacteria

This network analysis shows the distribution of oral sites in the human mouth based on the taxonomic units identified in ~6 million bacterial 16S rRNA gene reads by oligotyping. Samples were obtained from 148 healthy individuals; the oral cavity of each individual was sampled at 9 locations. Each circle represents a sample and is colored based on which oral site it is from. Clustering of the oral sites shows that samples from the same oral site across individuals are more similar to each other than samples from the different oral sites in a single individual.

Printable version (pdf) Contact: Gina Hebert 508-289-7725; ghebert@mbl.edu   MBL, WOODS HOLE, MA—A new computational method for analyzing bacterial communities has uncovered closely related, previously indistinguishable bacteria living in different parts of the human mouth. The technique, developed by Marine Biological Laboratory (MBL) scientists, provides high taxonomic resolution of bacterial communities and has the capacity […]
