Designing proteins that can sequence DNA

Sinduja Marx has long been interested in developing miniaturized, parallelized and personalized sequencing and diagnostics tools. As a molecular engineering grad student in the labs of physics professor Jens Gundlach, and Institute for Protein Design director David Baker, Marx is designing synthetic biological channels for nanopore DNA sequencing and molecular diagnostics. In this Q&A, Marx talks about her research and advice for prospective grad students.

Pacific oysters in the Salish Sea may not contain as many microplastics as previously thought

Using advanced instrumentation in the Molecular Analysis Facility, researchers in the lab of MolES faculty member and materials science & engineering professor Christine Luscombe have discovered that Salish Sea oysters may not contain as many microplastic contaminants as previously thought.

Researchers identify rules for effectively regulating gene expression in bacteria

Jason Fontana, a molecular engineering Ph.D. student in the labs of chemical engineering professor James Carothers and chemistry professor Jesse Zalatan, has identified features of bacterial genes that impose strict requirements on CRISPR-Cas transcriptional activation tools. This work defines new strategies to effectively regulate gene expression in bacteria, bringing researchers closer to their goal of using bacteria to produce valuable biosynthetic products. Read this Q&A with Jesse Zalatan featured on the Science in Seattle blog.

New system outcompetes traditional biofactories with on-demand, remote chemical production

A team was led by Dr. Alshakim Nelson, an assistant professor of chemistry at the UW, and Dr. Hal Alper, a professor of chemical engineering at the University of Texas, developed a new method that combines the bioactivity of microbes and a 3D-printed, synthetic hydrogel "” a water-based gel structure "” to create desired chemical compounds. The products can vary from pharmaceuticals to nutraceuticals, alluding to the vast potential for this new finding.

First-of-its-kind hydrogel platform enables on-demand production of medicines and chemicals

Researchers in the lab of MolES faculty member and professor of chemistry Al Nelson along with collaborators at the University of Texas unveiled a new way to produce medicines and chemicals and preserve them using portable "biofactories" that are embedded in water-based gels known as hydrogels. The approach could help people in remote villages or on military missions, where the absence of pharmacies, doctor's offices or even basic refrigeration makes it hard to access critical medicines and other small-molecule compounds.

PECASE Honoree Elizabeth Nance highlights the importance of collaboration in nanotechnology
