I’ve followed with interest your coverage of Michael’s research into use of copper to fight hospital infection. Of all the interesting papers covered in 2013, I think the one most actionable is episode 55, The Copper Room. His res... Read More
Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.
“This clearly shows that there is an association between oral bacte... Read More

When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More
