To discuss these questions, I spoke by phone with Gary Ruvkun, a molecular biologist and professor of genetics at Harvard Medical School. Ruvkun has what he admits are somewhat unusual opinions about life’s origins, and about the possibility of finding life elsewhere. In short, he questions the common assumption that our form of DNA-based life began on Earth. What began as an interview about the methane discovery turned into a discussion about why he wants to send something called a DNA sequencer to Mars. (After our conversation, NASA announced that the methane concentrations had descended back to their usual levels, further confounding scientists.) During our conversation, which has been edited for length and clarity, we also discussed the ways in which scientific debates about the origins of life intersect with religious ones, the reasons he might be dead wrong, and what it feels like to hold a minority opinion in the scientific community.
Did the Internet community peak at bookmarks? Asked in a different and perhaps more complete way: just as technologies like RSS and email in their purest forms are hard to beat even as technology marches forward, what better technology exists to keep track of information on the ever-expanding Internet than bookmarks? Taken a step further, what better way to share the bookmarked information than a site of your own? As such, I‘ve been reading, which is why I write now.
Working in and having a passion for libraries, I am struck by the fact that the way bookmarks work in the physical world is not directly analogous to bookmarks in the digital world. Bookmarks in the digital world are instead like dog-eared pages or highlighted passages; if you think of the Internet as a single tome, that is. In any case, anything that moves you to deface a book should probably be shared or become immortalized in some other way than just a reference for a future version of yourself.
