Student Centered Learning, Part I: Nanobiographies

Students learn in many different ways than simply taking tests. In my Microbiology course, I have students write a length term paper (a "Microbiography"). As part of this process, students create one page "summaries" of their microbial topic, which I call "Nanobiographies." In this blog post,... Read More

Antimicrobial peptides induced by herpesvirus enhance HIV-1 infection

The risk of being infected with human immunodeficiency virus type 1 (HIV-1) is substantially enhanced in individuals with other sexually transmitted diseases. For example, infection with herpes simplex virus type 2 (HSV-2) increases the risk ratio of acquiring HIV from 2 to 4. Explanations for t... Read More

Early Origins

Archaeans are among the earliest forms of life that appeared on Earth billions of years ago. It’s now generally believed that the archaea and bacteria developed separately from a common ancestor nearly 4 billion years ago. Millions of years later, the ancestors of today's eukaryotes split off... Read More

Porcine circovirus DNA in rotavirus vaccine

The US Food and Drug Administration has recommended that administration of the Rotarix vaccine, which protects against rotavirus infection, be suspended. This action comes after an independent research group found that the vaccine contains DNA of porcine circovirus type 1. Read More

Rating Pandemics: Tweaking the WHO Scale for Next Time…

The title pretty much sums up the main thrust of the post, which also includes section on cheap, rapid diagnostic tests that not only can identify known pathogens, but provide quite a bit of information about novel pathogens (link to a great Pop!Tech video lecture by Ian LIpkin). There's also a ... Read More

Effectiveness of this season’s influenza vaccine

The Centers for Disease Control and Prevention has released early estimates of the effectiveness of this season’s influenza vaccine in preventing influenza infection. Estimated vaccine effectiveness is 62%. But even if you get infected after immunization, you are likely to have reduced illness, ... Read More

Evidence-based antibiotic usage

New recommendation encourages physicians to prescribe _antibacterials_ instead of antibiotics for bacterial infections. This recommendation is based on compelling evidence that the word "antibiotic" confuses almost everyone, including some doctors. The confusion leads to strong patient demands... Read More

Receptor for new coronavirus-EMC identified

Viruses are obligate intracellular parasites, which means that they must enter a cell to reproduce. As virions are too large to diffuse passively across the plasma membrane, cellular pathways for uptake of extracellular materials provide entry routes. The first step in entry is adherence of viru...

Using Wordcloud-Reponses to Discover How Students Perceive Concepts in the Classroom

In this blog, I share some "first word that comes to mind" responses of my freshman biology class to the words "germ," "bacteria," "cell," and "DNA." The way that we perceive an idea or concept definitely impacts our relationship with it. Thus, finding out what students think, coming into our ... Read More
