Impacts of Beach Oiling on Coastal Microbes

April 17th, 2014 @

The beach ecosystems along the northern Gulf Coast underwent a major disturbance in the months following the blowout of the Deepwater Horizon drilling rig and its release of the equivalent of 4.9 million barrels of oil.  In 2013 Bay Paul Center scientists published a study of the changes in microbial community composition from oil hydrocarbon contaminated sands at 7 coastal sites that experienced […]

New Methods for Detecting Variation in Microbial Communities

April 8th, 2014 @

Bacteria comprise the most diverse domain of life on Earth, where they occupy nearly every possible ecological niche and play key roles in biological and chemical processes. Studying the composition and ecology of bacterial ecosystems and understanding their function are of prime importance. Standard methods of analyzing microbial communities often fail to resolve ecologically meaningful […]

Huber Lab Research Update

April 8th, 2014 @

The laboratory of Julie Huber is investigating the microbial communities of the rocky subseafloor at Axial Seamount, an active submarine volcano that is part of the NSF Oceans Observatory Initiative seafloor cabled observatory.  In 2013 they reported the first combined molecular and microscopical analysis of microbial communities in a “snowblower vent,” an ephemeral and uncommonly observed […]

Uncovering the Secret World of the Plastisphere

February 28th, 2014 @

HONOLULU – Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals. New research being presented here today delves deeper into the largely unexplored world of the “Plastisphere” – an ecological community of microbial organisms living […]

Susie Theroux awarded her Ph.D.

December 28th, 2012 @

Speaking to a live audience in Providence and over videolink to Woods Hole, Susanna Theroux defended her dissertation on November 28th, 2012. Theroux described her doctoral research that was completed in collaboration between the labs of Dr. Yongsong Huang at Brown University’s Department of Geological Sciences and Dr. Linda Amaral-Zettler at the MBL’s Bay Paul […]

Anupriya Dutta awarded her Ph.D.

December 28th, 2012 @

On December 5, 2012, Brown-MBL Graduate Student, Anupriya Dutta, successfully defended her PhD dissertation, ‘Recognizing microRNAs (miRNAs) in Microinvertebrates and Confirming their Absence.’ Bdelloid rotifers are aquatic microinvertebrates that have several outstanding qualities among metazoans. They make up the only ancient asexual animal lineage. Bdelloid rotifers are also incredibly robust to DNA damage, which is […]

Systems-level analysis of microbial community organization through combinatorial labeling and spectral imaging

December 7th, 2012 @

Valm, Alex M., Jessica L. Mark Welch, Christopher W. Rieken, Yuko Hasegawa, Mitchell L. Sogin, Rudolf Oldenbourg, Floyd E. Dewhirst, and Gary G. Borisy (USA) 108: 4152-4157 Bacteria in nature live not as isolated cells, but as members of a community in which many different kinds of bacteria live intermingled in complex associations. The spatial […]

Microbial community composition in sediments resists perturbation by nutrient enrichment

December 7th, 2012 @

A paper from Mitch Sogin and Hilary Morrison et al A microbial community’s functional capability—what it eats, what it produces—is thought by some to be more meaningful than the identities of its members.  Functional redundancy in bacterial communities thus allows communities to survive environmental disturbance even if the membership changes.  Others believe that microbial communities […]

A widespread class of reverse transcriptase-related cellular genes

December 7th, 2012 @

Publication by Eugene A. Gladyshev, Irina R. Arkhipova We describe a novel class of single-copy reverse transcriptase (RT)-related genes that do not constitute part of any mobile genetic element, and are clearly distinct from the only known non-mobile RT genes, the telomerases, which maintain chromosome ends in eukaryotes. These RT-like genes are of ancient origin, […]
