Prologue – Why is there a conference about sea urchins?
This year I went to my first multi-day conference as a graduate student, the Developmental Biology of Sea Urchins conference at the Marine Biology Laboratory, located in Woods Hole, Massachusetts. I was a little nervous, because I didn’t feel like I knew all that much about the field, and also because I had no idea how it was possible to spend four days talking about sea urchins. Then I realized that every researcher will have to attend their first conference at some point, so I decided to write about the experience for all of you who want to know what happens when you get 100 scientists together who all work on the same problems.

“I could exceedingly plainly perceive it to be all perforated and porous, much like a Honey-comb, but that the pores of it were not regular. . . . these pores, or cells, . . . were indeed the first microscopical pores I ever saw, and perhaps, that were ever seen, for I had not met with any Writer or Person, that had made any mention of them before this. . .”1 With these words, 17th century scientist and professional British person Robert Hooke realized there is literally more to life than we can see with our eyes.

Last time, we went through two reasons why antibiotics may not be necessary in hand soaps. First, there has not been very much study about how safe these antibiotics are, especially Triclosan. Because we don’t know for sure, the FDA wants antibiotic manufacturers to be certain that their soaps are safe. But the second argument went into reasons why the antibiotics may not be needed at all. Research from Columbia and the University of Michigan reviewed papers back to the 1960s and found that the best way to reduce the risk of infection is to wash your hands, but what kind of soap is used is much less important than the duration1. So the antibiotics may be unsafe, particularly to the environment, and they may not be necessary. Today, the final part of the argument will show how antibiotics in consumer hand soaps may, paradoxically, be detrimental to health. Continue reading
Recently, I saw an article about how the FDA wants to remove antibiotics from hand soap1. To most people, this sounds silly. Antibiotics kill bacteria, and bacteria make you sick, so why should we get rid of this? In fact, reviewers from Rutgers read past papers in late 2011 and found that antibacterial soaps (soaps containing antibiotics) significantly reduce the amount of bacteria on a person’s hands2. As it turns out, the world of bacteria is a very active area of science, and we are learning more about how bacteria interact with us and each other every day. Recently, evidence has suggested a few problems with the most common antibacterial soaps. What are some of these problems, and why are they resulting in new FDA regulations?
