Healthcare Consulting: A Door to the Business of Life Sciences

Posted by Guest Blogger on Oct 13, 2016 10:30:00 AM

This post was contributed by guest blogger Gairik Sachdeva.

Healthcare consulting is a fast-paced field, requiring people who are willing to quickly learn, and apply their knowledge to a variety of problems. In this post, I’ll share what I’ve learned as a healthcare consultant and give you an idea of what a career in this field involves, and why you might enjoy doing it. I’ll also talk about the skills you’ll need to do well as a healthcare consultant and what you could do to break into the field.

CRISPR 101: Engineering the Plant Genome Using CRISPR/Cas9

Posted by Joel McDade on Oct 11, 2016 10:30:00 AM

CRISPR has taken the genome engineering world by storm owing to its ease of use and utility in a wide variety of organisms.  While much of current CRISPR research focuses on its potential applications for human medicine (1), the potential of CRISPR for genome engineering in plants is also being realized. There are a variety of reasons to consider using genome editing to change the genetic code of plants, including the development of crops with longer shelf life and the development of disease-resistant crops to increase agricultural yield (2,3). While it is certainly possible to select for desirable traits using traditional plant breeding approaches, these techniques are cumbersome, often requiring several rounds of selection to isolate plants with the phenotype of interest. Genome engineering, on the other hand, allows for targeted modification of known or suspected genes that regulate a desired phenotype.  In fact, CRISPR has already been used to engineer the genome of many plant species, including commonly used model organisms like Arabidopsis and Medicago truncatula and several crop species including potato, corn, tomato, wheat, mushroom, and rice (4). Despite the almost universal functionality of the CRISPR system in most organisms, some plant-specific changes to CRISPR components are necessary to enable genome editing in plant cells.

Grad School Advice Part 2: Building Community

Posted by Tyler Ford on Oct 6, 2016 10:30:00 AM


In this second episode of our two-part series, we continue our conversation with Niroshi Senaratne and Ben Vincent from the Biological and Biomedical Sciences program at Harvard University and pick their brains on how they've managed to keep themselves happy during their time in grad school
. As you'll learn, grad school has its ups and downs for everyone but you can come out on top if you leverage your community, think hard about picking a good mentor, and begin considering career options early. Tune in for great advice on all of these topics.

Sequencing Options for CRISPR Genotyping

Posted by Guest Blogger on Oct 4, 2016 10:30:00 AM

This post was contributed by guest blogger Søren Hough, the Head Science Writer at Desktop Genetics.

One of the most important steps in the CRISPR experimental process is validating edits. Regardless of which CRISPR genome editing system you use, there remains a chance that the observed phenotype was caused by an off-target mutation and not an edit in the target gene.

The validation process, also known as CRISPR genotyping, is critical to demonstrating causal relationships between genotype and assayed phenotype. Verifying these connections can help alleviate the reproducibility crisis in biology. It is key to address these concerns as CRISPR use grows across the life sciences and to establish standardized validation techniques for academia, industry, and especially the clinic.
