I have found that students become involved, energized, and enthusiastic when I give them opportunities to explore topics in my classes using their own creative approaches and interests. So this semester, in my Biology 111 course at the University of Puget Sound, I found that students explored f... Read More
Colony collapse disorder (CCD) has caused such a profound drop in honeybee populations that even the U.S. Congress is addressing the issue: Senator Jeff Merkley (D-Oregon) has proposed the Pollinator Recovery Act to preserve pollinator habitat. The rapid decline in these important pollinators af... Read More
This episode: Bacteria in hydrothermal vents that feed their host tubeworms evacuate when their hosts perish!
(9 MB, 9.8 minutes)
Bacteria acquire and spread genetic information through several means. Some bacteria form a long, thin tube called a pilus, mediating transfer of DNA by direct cell-to-cell contact, in a process known as conjugation. Some bacterial take up environmental DNA and incorporate it into their existing... Read More
Is the way to treat heart disease through a person's stomach? According to a new study, the answer is yes. Researchers have found that a compound found in red wine, resveratrol, reduces the risk of heart disease by changing the gut microbiome.
Cardiovascular disease remains the leading cause ... Read More
Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years.

A central pursuit of microbial ecology is to accurately model changes in microbial community composition in response to environmental factors. This goal requires a thorough understanding of the drivers of variability in microbial populations. However, most microbial ecology studies focus on the ... Read More
Pneumonia remains a serious worldwide problem, especially among the young, elderly, and immunocompromised. Over 900,000 children die each year due to the disease, and respiratory syncytial virus (RSV) is the most common viral cause (Streptococcus pneumoniae and Haemophilus influenzae type b bein...
