@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.

The technique, developed by Marine Biological Laboratory (MBL) scientists, provides high taxonomic resolution of bacterial communities and has the capacity […]

Contact: Diana Kenney dkenney@mbl.edu; 508-289-7139 WOODS HOLE, Mass.— As forests age, their ability to grow decreases, a new study by Marine Biological Laboratory (MBL) scientists and colleagues has determined. Since most U.S. forests are maturing from regeneration that began about 100 years ago when extensive clear-cutting occurred, the study suggests the future growth of U.S. […]
