The long battle between humans and infectious microbes has left its marks all over us.

It shows up most obviously in the way our bodies are constructed. The thousands of species of bacteria that swarm over us cannot penetrate our multilayered skin. Entry points, such as the eyes and nose, are bathed in moisture to help flush out pathogens. The lining of our lungs releases bacteria-killing compounds. Viruses that manage to infect cells are greeted by proteins that attempt to shred them into genetic confetti. Any pathogen that sneaks past all these defenses then faces an army of immune cells, which can devour and destroy the invaders. Immune cells can also manufacture antibodies, which allow them to launch swift attacks if they encounter the same infection elsewhere in the body.

Over the past two summers I’ve paid visits to the lovely Isles of Shoals to speak to students and scientists at the Shoals Marine Lab. (I wrote a post about my 2007 trip here, and last summer’s journey here.) This year I’ll be trying something new: I’m teaching a week-long college-credit course on science writing. It will run from August 10 to 17, and, like all classes at Shoals, it will be intense. We’ll read a lot, write a lot more, and take advantage of the unique environment of Appledore Island, where you should never be surprised to encounter an underwater archaeologist, an ornithologist banding migratory birds, or a vet dissecting a seal on a picnic table.

When I recently gave a talk at Rockefeller University, I met a remarkable grad student named Alexis Gambis, who has organized the Imagine Science Film Festival. Last year was its launch, and this year they’re at it again. Alexis asked me to be on the jury, and while I warned him that I think bad science makes for good science fiction, I signed on. They’re now eager for submissions–visit their web site for more details. I’ll be waiting to watch.

I had to spend a couple hours this morning footnoting my next column for Discover so that it can be fact-checked. I had to assemble the papers I read, the web sites I visited, and the contact information for scientists who helped me understand the subject. One of Discover‘s intrepid fact-checkers will then spend many hours following in my footsteps and discovering where I tripped. He or she will have no compunction about writing up a detailed report of my mistakes. I’m sure some mistakes will turn up, and I won’t be angry to see them in a fact-checking report. I’ll be grateful that my column won’t inadvertently misrepresent someone’s research. And I’ll be personally glad to have any misunderstanding of mine put straight.
