Jon Wilker shows us some of his latest chemistry projects and what his typical day is like inside and outside the lab.

Mary Ann Moran of the University of Georgia on "Metatranscriptomics of Marine Microbial Communities" at the 6th annual Genomics of Energy & Environment Meeting on March 24, 2011.

In episode 50 of MicrobeWorld Video, Vincent, Michael, and Stanley recorded episode #8 of the podcast This Week in Microbiology live at the 2011 ASM General Meeting in New Orleans, with guests Andreas Baümler, Nicole Dubilier, and Paul Rainey. They spoke about how pathogens benefit from disease, symbioses between chemosynthetic bacteria and marine invertebrates, and repetitive sequences in bacteria.

DOE JGI Deputy Director Jim Bristow on the Community Sequencing Program at the 6th annual Genomics of Energy and Environment Meeting on March 23, 2011.

Peer Bork of the European Molecular Biology Laboratory on "Comparative Metagenomics of Gut and Ocean: Identification of Microbial Marker Genes for Complex Environmental Properties" at the 6th annual Genomics of Energy & Environment Meeting on March 23, 2011.

Rex Malmstrom of the DOE Joint Genome Institute discusses single-cell sequencing of Prochlorococcus on June 4, 2010 at the "Sequencing, Finishing, Analysis in the Future" meeting in Santa Fe, NM.

Topsail Island, North Carolina is a northern nesting beach of threatened Loggerhead Sea Turtles. Here the residents have helped protect the turtles that visit the island during the nesting season. Beach walkers watch for turtle nests, pick up trash and report injured turtles. The island commerce has decided not to import new sand like most beaches, so the composition of the sand for incubation of turtle eggs doesn't change. The Karen Beasley Sea Turtle Rescue and Rehabilitation Center was...

Unicellular eukaryotes are responsible for a massive amount of photosynthetic carbon fixation in marine systems. The smallest among these fall within the “pico” size fraction (<2 micrometers in diameter), are broadly distributed – from coastal to open-ocean environments – and are highly diverse. Picoeukaryotes contribute a significant proportion of the biomass and primary production within this size fraction, often rivaling their cyanobacterial counterparts Prochlorococcus and...

Sequencing the expressed genetic information of an ecosystem (metatranscriptome) can provide information about the response of organisms to varying environ mental conditions. Until recently, metatranscriptomics has been limited to microarray technology and random cloning methodologies. The application of high-throughput sequencing technology is now enabling access to both known and previously unknown transcripts in natural com munities. We present a study of a complex marine meta...

Ichnology for the 21st Century: Understanding the differences between continental and marine trace fossils, with implications to the diversity, distribution, and evolution of soil biota ; Department of Geological Sciences, San Diego State University, Seminar Series ; The study of ichnology has come a long way since its inception and it continues to evolve. In particular, progress is being made in understanding the implications of trace fossils in the continental realm and how they can be...
