Introduction to your microbiome

From the NYT--most of the cells that comprise you do not contain your DNA:

I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a laboratory located at the BioFrontiers Institute at the University of Colorado, Boulder. As part of a new citizen-science initiative called the American Gut project, the lab sequenced my microbiome — that is, the genes not of “me,” exactly, but of the several hundred microbial species with whom I share this body. These bacteria, which number around 100 trillion, are living (and dying) right now on the surface of my skin, on my tongue and deep in the coils of my intestines, where the largest contingent of them will be found, a pound or two of microbes together forming a vast, largely uncharted interior wilderness that scientists are just beginning to map.

Ressurrecting the F1 rocket

Wired has published an article that ties the present space program to the highly successful Apollo program many decades ago. We might be on the verge of recreating the F1 rocket engine. Lots of amazing facts and figures here:

There has never been anything like the Saturn V, the launch vehicle that powered the United States past the Soviet Union to a series of manned lunar landings in the late 1960s and early 1970s. The rocket redefined "massive," standing 110 metres in height and producing a ludicrous 34 meganewtons of thrust from the five monstrous, kerosene-gulping Rocketdyne F-1 rocket engines that made up its first stage.

Even scientists tend toward magical (teleological) thinking

In his new book, psychologist Matthew Hutson has documented many instances in which all of us latch onto what he terms "magical thinking." Hutson argues that this is not necessarily a bad thing--we do it to keep our sanity in this crazy dangerous world, in which our final destiny is certain death.  Nor is magical thinking aways a good thing.  Hutson's book is an excellent read full of intriguing and often counter-intuitive observations, many of them based on rigorous experiments. Hutson is also authors a blog at Psychology Today.  In a recent post, he notes that even scientists are susceptible to "magical thinking," which often takes the form of teleological thinking:

Over the years, a number of psychologists have suggested that we are promiscuously teleological. Telos is Greek for end or purpose, and teleology is the belief that an object was created or an event occurred to fulfill some purpose. You believe there’s not just a how but a why to its origin, that there’s a mind with intentions behind it. And when an event seems especially meaningful (such as a hurricane destroying your home) or an object seems especially complex (such as the human body) the prospect of a designer appears all the more likely. Some things really are designed—watches do come from watchmakers—but most of the universe isn’t.
