I finally got around to reading Carl Zimmer's highly-recommended National Geographic
article about antibiotics and their effect on our microbiome, the "100 trillion microbes that live in our healthy bodies."
Scientists are only now beginning to get answers to those questions. In a paper just published online in the journal Gut, Andres Moya of the University of Valencia and his colleagues took an unprecedented look at a microbiome weathering a storm of antibiotics. The microbiome belonged to a 68-year-old man who had developed an infection in his pacemaker. A two-week course of antbiotics cleared it up nicely. Over the course of his treatment, Moya and his colleagues collected stool samples from the man every few days, and then six weeks afterwards. They identified the species in the stool, as well as the genes that the bacteria switched on and off.
What’s most striking about Moya’s study is how the entire microbiome responded to the antibiotics as if it was under a biochemical mortar attack. The bacteria started producing defenses to keep the deadly molecules from getting inside them. To get rid of the drugs that did get inside them, they produced pumps to blast them back out. Meanwhile, the entire microbiome powered down its metabolism. This is probably a good strategy for enduring antibiotics, which typically attack the molecules that bacteria use to grow. As the bacteria shut down, they had a direct effect on their host: they stopped making vitamins and carrying out other metabolic tasks.

Bikram Choudhury, the millionaire accused serial rapist who popularized hot yoga in America, sued other hot yoga studios in 2003, including “open source yoga” practicioners, asserting that he held a copyright over the sequence of poses conducted in his class.
Endorphins may have been getting too much credit for “runner’s high,” that euphoric lift we get when we exercise intensely.
When I was a kid, I was terrified of farting in class. At home, it was no big deal: it was a daily fart festival with my family. But at school? TOTAL FEAR OF FLATULENCE. But then it dawned on me: EVERYBODY FARTS. And that’s one of the reasons why I’ve decided to write a graphic novel about how our bodies work. It’s about all the stuff that goes on inside our bodies daily, or throughout our lives, and that this stuff – whether it’s digestion, or respiration, or defecation – is necessary for us to live. And it gives you excellent come-back material if anyone teases you for farting in school!
