A lot of our colleagues are interested in bioinformatics and data science. While it is clear that bioinformatics is important, even essential, in modern biology research, there is the question about the levels of programming and computer skills needed for different jobs. I'm not going to answer that question here. Instead I'm going to focus on one end of the problem, that is, how is a bioinformatician similar to a data scientist? I'll illustrate the kinds of skills that are needed for this role by sharing my recent experience of how we moved the Discovering Biology in a Digital World (DWB ... Read more

A simple web search says biotech is really big. One estimate indicates that the industry will have $400 billion in sales in 2017 with growth to over $775 billion by 2024 [1]. Another report suggests there are over 77,000 employers [2]. That’s big, but is it real, and what you can do with this information?

At Biotech-Careers.org we're interested in helping students and graduates of biotech programs at community and four-year colleges learn about the multitude of opportunities available in the biotech industry. To be helpful we ... Read more

Last fall, Dr. Thomas Tubon and I presented a Bio-Link webinar on Genome Engineering with CRISPR-Cas9. Since my part will be to help our audience understand the basics of this system, I prepared a short tutorial with Molecule World . Enjoy!

For many years, many of you have been using our popular BLAST for beginners tutorial and the BLASTing through the kingdom of life activity. We decided with the recent updates to the NCBI BLAST pages that it was a good time to update the tutorial and some of the sequences as well. In the tutorial, we've added images that represent the current web pages at the NCBI. For our data set of sequences, we made a couple of the sequences longer, to remove the ambiguity in determining which sequence matches the query best.

Of course, this meant that we also needed to update the answer key. ... Read more

Scale, proportion, and quantity belong to one of the cross cutting concepts in the next generation science standards (NGSS). According to Volume 2 of the NGSS, "in engineering, no structure could be conceived much less constructed without the engineer's precise sense of scale." The authors go on to note that scale and proportion are best understood using the scientific practice of working with models. Read more

We feel interesting and sometimes painful sensations when capsaicin, from chilis, and the allyl isothiocyantes from wasabi,bind to receptors in our mouths. In this article, we look at the structures that communicate information to the cell. How do they tell the cell that capsaicin or wasabi compounds are bound? Read more

Digital World Biology is happy this summer to be partnering with Shoreline Community College and NWABR to help students attending their summer camps, Project Biotech and Camp BIOmed , explore 3D structures of proteins, DNA, chemicals and other substances, in Molecule World.

At one time, scientists didn't even consider working ... Read more
