Linda Wegley Kelly, PhD, a marine microbial ecologist in the Department of Biology at San Diego State University, talks to contributing editor Tanuja Koppal, PhD, about what has changed in the field since 2001, when she started working in the lab. While genomic and sequencing technologies have become easier and cheaper, the work on the bioinformatics side has now become more tedious in terms of the volume of data that needs to be analyzed. While systems for sample collection and storage have become convenient and customizable, the use of automation in microbiology remains fairly limited. Contamination still remains a cause for concern, and protocols have to be rigorously outlined and implemented.

Forest Rohwer, PhD, is a professor in the Department of Biology at San Diego State University. He is a fellow of the American Academy for Advancement of Science (AAAS), American Academy of Microbiology
(AAM), and Canadian Institute for Advanced Research (CIFAR). He led the development of viromics,” which involves isolating and sequencing the RNA/DNA from all the viruses in a sample. From this data, it is possible to determine what types of viruses are present and what functions they are encoding. Dr. Rohwer uses viromics to study ecosystems ranging from coral reefs to the human body and has shown that most genomic diversity on the planet is viral. Dr. Rohwer has published more than 150 peer-reviewed articles, was awarded the International Society of Microbial Ecology Young Investigators Award in 2008, and is listed as one of the World’s Most Influential Scientific Minds (Thomson Reuters 2014).

Freeman Technology has published a new white paper that describes extensive experimental studies examining the multiple mechanisms that lead to powder caking. Caking is a routinely encountered problem within powder handling applications which compromises productivity and increases waste.

Malvern Instruments has released new guidance on using automated image analysis to detect and quantify agglomerates. The ability of uncontrolled agglomeration to substantially impact the performance and value of powder products makes efficient agglomerate detection vital across a number of industries.
