Urban versus rural nature

14 Sep

Maybe it’s in the zeitgeist: this week’s New York magazine waxes poetic about ecology in  The Concrete Jungle. Not what I was expecting when the city has been teeming with fashionistas and urban wildlife on the pop edge of culture. But, there it is in the first photo: Staten Island turkeys!

In our heat island, enveloped by concrete and lush parks engineered to look natural, the nuance here goes beyond rabid coyotes and bears in the suburbs.

An ecological feedback loop is a natural extension of the idea that nature exists in the city, but it requires a change of thinking that is equally profound: There is no difference between urban nature and rural nature. It is all one ecology, adjusting and cross-pollinating in the face of change. This can be disturbing, since local stresses threaten to disrupt wildlife hundreds of miles away. But it is, in fact, a hopeful idea. If New York City’s ecology has taught us anything, it is that nature likes intrusions—counts on them, even. Change makes for vibrancy. We are not just a city of bedbugs and rats; we are a wellspring for regional vitality.

But it’s a challenging metaphor for the City and our global community. As urban dwellers, we’re both part of the problem and part of the solution.

Scientists believe genetic diversity is as important to species survival as sheer numbers. It has a lot to do with the mix, in other words, and if it is characteristic of human nature to look at things metaphorically, then it turns out that the city serves the same function for nature as it does for human beings. It is an intersection, a place where outsiders arrive to set up camp anew, to commingle, to move on, carrying influences and encouraging dynamism elsewhere. Like cities in the seventies, our global ecosystem is in trouble; we are flirting with environmental bankruptcy. If we are to save nature—which is to say, save ourselves—then we need to embrace that which is around us.

Over Labor Day weekend, I got to spend time on a friend’s farm in western Colorado– a wonderful experience that left me more than a wee-bit jealous of wide-open rural spaces. I love my city, too, and I’m glad to appreciate it as nature, too.

UPDATE Sept 30th: This post got a nice shout-out in New York magazine’s comments.

Molecule of the Week: Water

It’s been a rainy week in New York City, and my office next to our front porch and my container garden has me thinking about that ubiquitous wetness. It’s been soaking my plants, and after a quick errand on Friday afternoon, its dampness lurked for hours on the hem of my jeans.

It’s easy to take the wonder of water for granted because it’s everywhere, but its physical properties are anything but ordinary. Almost all solids of any substance are more dense than their liquid counterparts. But if ice were more dense than liquid water, ice cubes wouldn’t float in cool drinks on a summer day. Ice wouldn’t freeze at the tops of cold lakes (no ice skating), and polar ice caps would be more like suboceanic ice cushions. If water were a normal liquid, the Earth would look really weird.

The molecule itself is bent, lending hexagonal elegance to snowflakes. In a liquid the molecules glom to each other, not quite like superglue. But that watched pot (that seemingly never boils) needs lots of energy to release water into steam.

For those of us who’ve built molecules for a living, water is often our enemy, something that can get in the way and keep the right components from getting together. But Nature incorporates water beautifully, using the molecule as a structural tool and as a critical player in the reactions that make life work. Forced to take some tricks from Nature in my own graduate work (my highly charged molecules wouldn’t dissolve in any other solvent), working in water was like learning a related foreign language. I learned some basic grammar and vocabulary, but fluency of water chemistry is a challenge beyond the synthetic lab. By Nature’s standards, I was, perhaps, third rate.

I missed the AMNH’s exhibit on Water when it was in NYC (but I think it’s still touring, check your local science museum). As climates change, ice melts, sea levels rise, more intense storms brew in the oceans, water sits at the heart of the environmental challenge. According to the World Health Organization, as of 2002, nearly 20 percent of the world’s population didn’t have access to healthy, sanitized drinking water supplies.

Three atoms hooked together connect to the inner workings of life, health, the environment and public policy.


The Webbys of Science

5 May

Daily blogging this month made for an excellent excuse to browse the 2009 Webby nominees and winners.

The science nominees included Nature, Scientific American, and Wired Science. As a science journalist, these three are already on my regular web diet, so I didn’t feel the need to take a closer look.

The Webby winner, NASA JPL’s Cassini site, has been redesigned since I last looked at it. It’s visually stunning, smooth and intuitive, with beautiful graphics and clear explanatory information. And, honestly, I don’t know of anyone who doesn’t think that Saturn and its rings are cool.

But, my favorite is another nominee, The Exploratorium’s Evidence: How do we know what we know?. This site completely blew me away with it’s explanatory clarity, its beauty, and its ability to boil the tough topic of how scientific evidence works into a clear set of questions and a process. It’s interactive– it lets participants map how they gather and weigh evidence, and it illustrates a great scientific question, the origin of human beings. It brings the best of the Exploratorium‘s interactive approach to understanding science to the web.

The beauty of science is that evidence isn’t static: scientists are constantly making new discoveries and shifting their notions of what data means based on the greater context of available information. That intellectual give and take is the life-blood and culture of science. How science works, a series of questions illustrates the scientific method in the clearest, most intuitive way that I’ve ever seen.

I often have a conflicted relationship with scientific information on the internet (she says, ironically, as she writes about science on the web). I love that I have access to so much information so easily, and the internet makes my job possible. I’m also frightened by the massive amounts of inaccurate, outdated or even misleading information that I sometimes find on websites and blogs.

However, scientific information presented this well on the internet is a true masterpiece. Congratulations Science Webby nominees and winners!
