Get that next job-how to break out of the postdoc trap.

In the past, the majority of graduate students and postdoctoral researchers were focused on careers in academia. Times have changed, and many are now considering careers outside of academia and are aware of numerous exciting career opportunities in industry and nonprofit and government organizations. However, although it is easy to find resources about academic careers, the same cannot be said for positions outside the ivory tower.

Simple system for isothermal DNA amplification coupled to lateral flow detection.

Infectious disease diagnosis in point-of-care settings can be greatly improved through integrated, automated nucleic acid testing devices. We have developed an early prototype for a low-cost system which executes isothermal DNA amplification coupled to nucleic acid lateral flow (NALF) detection in a mesofluidic cartridge attached to a portable instrument. Fluid handling inside the cartridge is facilitated through one-way passive valves, flexible pouches, and electrolysis-driven pumps, which promotes a compact and inexpensive instrument design.

Biochemical analysis and scanning force microscopy reveal productive and nonproductive ADAR2 binding to RNA substrates.

Scanning force microscopy (SFM) can be used to image biomolecules at high resolution. Here we demonstrate that single-molecule analysis by SFM complements biochemical data on RNA protein binding and can provide information that cannot be obtained by the usual biochemical methods. We have used this method to study the interaction between the RNA editing enzyme ADAR2 and RNA transcripts containing selective and nonselective editing sites.

Analysis of RNA flexibility by scanning force spectroscopy.

Scanning force spectroscopy was used to measure the mechanical properties of double stranded RNA molecules in comparison with DNA. We find that, similar to the B-S transition in DNA, RNA molecules are stretched from the assumed A' conformation to a stretched conformation by applying a defined force (plateau force). The force depends on the G + C content of the RNA and is distinct from that required for the B-S transition of a homologous DNA molecule.
