Biotech Basics: Accuracy and Precision in Measurements (and a #SciArt Project!)

  What is the difference between accuracy and precision? Accuracy describes how close a measurement is to the true value of a given quantity.  Precision describes the reproducibility of the measurement. Accordingly, measurements can be categorized as follows: Neither accurate…

Why is C. elegans so popular in the biology laboratory? 

For centuries, scientists have used model organisms from the three domains of life, bacteria, archaea, and eukaryotes, to understand biological functions. For example, the bacterium Escherichia coli (E. coli), which has been studied for more than 60 years, has provided important…

DNA Sequencing to Save Endangered Species

Since the 1980’s, DNA evidence has been used in the criminal justice system to help convict violent offenders and, just as importantly, exonerate innocent individuals. An approach often used is DNA profiling, a technique where investigators compare the base pair…
