Fluorescent Controversy...

After conducting a bacterial transformation lab with my students, where we genetically engineer the bacteria to make a jellyfish protein that fluoresces, we always jump into the discussion of why this technique is important.  I always try to get the students to think of ways that this could benefit them.     Among other uses, we finally get to the idea that these bacterial cells can be used as...

Human Genome Project...

The initial goal of the Human Genome Project was to find, map and sequence all of the genes within the human genome.  Since the completion of the initial draft back in 2000, the White House predicted that this would lead to a new era of molecular medicine, bringing new ways to prevent, diagnose, treat and cure disease.  It has been amazing to see what we have learned since then, but even more interesting...

Pharm Crops...

What if vaccines could be eaten instead of injected?  Scientists began developing subunit vaccines in the late 1980s; these are vaccines which contain isolated pathogen proteins.  It seems that proteins from viruses, bacteria, and parasites can trigger an immune response (are antigenic) even when the pathogens are not present.  Furthermore, these proteins can be antigenic when eaten, which has led...

Sexual Selection...

When we think about all of the living things on Earth, we immediately see how different we all are from each other.  Many of these traits that might seem bizarre to us, evolutionarily speaking, have a tremendous amount to do with the survival.  Many traits have been selected for by the opposite sex, because it will help the passing on of their design information.  One very amazing example of this...

Whole Genome Sequencing: Mutation Diagno...

Two Scientific teams independently attempted a new approach to discovering the cause for certain diseases by sequencing the whole genome of their patients. This technique was done not only to help their current patients but hopefully to shed light on other common killers such as heart disease, diabetes and Alzheimer’s. One Scientist from Baylor College of Medicine in Houston Texas, Richard A. Gibbs,...
