Summertime in the Peck Lab!

The laboratory is hoppin’ this summer! Kate and Hoang are continuing their work from the spring semester, Anna has returned from study abroad, and Matthew is getting started. Serena continues her research work before she moves on to her laboratory instruction position in the fall semester.

Anna excited to properly practice sterile technique!

Kate thrilled to be checking DNA concentration!

Matthew intently preparing to conduct gel electrophoresis!

Serena and Hoang preparing to analyze genotypes!

Peck Lab presents at CLAS

The Peck lab is well represented at the Colby Liberal Arts Symposium (CLAS)! Em Shaw is presenting her work on identifying structual features of opsins that allow inhibition of lycopene elongase (link to poster). Abby Gregory is presenting more work figuring out how those hardy halophiles survive stress events (link to poster). In addition, Kiara Reed and Sammy Scofield (as part of their project in Applied and Environmental Microbiology) examined how we can crank up the pigment production by hacking the metabolism of H. volcanii.

Abby Gregory presents at the Experimental Biology meeting!

Abby (recently elected to Phi Beta Kappa) is presenting work examining how Haloferax volcanii respond to osmotic shock. This work was initiated by lab alum Margot Miranda-Katz. Abby and others in the lab have been hard at work testing how gene knockouts affect the ability of these critters to survive their dynamic environment.

Welcome to those following the QR code from the EB meeting! Here are the links:

Slides with a little more detail about the project

Paper in preparation with all the details about the analysis of the RNA sequencing data

Liked the format of the poster? – we used @mikemorrison’s template

Halophiles (our extreme favorites) live in the saltiest places on Earth. The Dead Sea, Utah’s Great Salt Lake and desiccating salt pans around the world are home these prokaryotes.

Extremophiles are organisms that live in environments that are toxic to most others. For example, thermophiles tolerate heat to the boiling point, acidophiles thrive in acid of pH 3.0 or below, xerophiles tolerate desiccation.
