Behind the Scenes of Creatures of Light

On Exhibit posts

Curator John Sparks will be blogging weekly about the upcoming exhibition, Creatures of Light, which opens on Saturday, March 31.

In just a little over a month, on March 31, the American Museum of Natural History will open our latest exhibition, Creatures of Light: Nature’s Bioluminescence,which focuses on the amazing diversity of organisms that produce light across every conceivable habitat. Every exhibition we produce is a collaboration between the Museum’s research scientists and the exhibition team, which includes writers, designers, artists, and media specialists. I’m the curator for this exhibition, which means that I oversee the scientific content and bring expertise from my research—in this case, on the evolution of bioluminescent signaling systems in marine fishes.We’re hard at work on the show this month, and I’ll be writing weekly posts from behind the scenes to offer some glimpses of what goes into producing a major exhibition. Here’s my first dispatch:

Podcast: Ray Jayawardhana: Strange New Worlds

Podcasts

In the past 16 years, astronomers have discovered more than 700 exoplanets, or planets that orbit other stars. If scientists find signs of life on these planets, it will profoundly impact everything from religion and philosophy to art and biology. In this podcast from the fall, astronomer Ray Jayawardhana shares some of the ideas from his book, Strange New Worlds, about life beyond our solar system.

Dr. Jayawardhana’s talk was recorded at the Hayden Planetarium on October 3, 2011.

Science Writer Carl Zimmer on Blogs, Books, and Tattoos

Q&As

When science writer Carl Zimmer noticed some scientists sporting serious tattoos, he wondered how many others enjoyed highbrow body art. After posing the question on his blog, Zimmer received a flood of responses and photos, many of which he recently compiled in his book Science Ink: Tattoos of the Science Obsessed. On Thursday, February 16, Zimmer will be one of four panelists at the Museum’s Beyond a Trend: Enhancing Science Communication Through Social Media, part of Social Media Week NYC. Zimmer recently answered a few questions about how new media are shaping his writing.

What could you do with a blog about science tattoos that you couldn’t do in a book, and vice versa?

Carl Zimmer: Blogs and books are different media, with different strengths and weaknesses. With a blog, you can spontaneously add things and make corrections. And people can make comments. Sometimes, people would point out that the equation in someone’s tattoo had a plus sign instead of a minus, which was probably pretty embarrassing. But since the blog was happening in real time, it was more disorganized. For the book, I was able to create miniature essays for various tattoos and arrange the tattoos in a logical progression from math to physics to chemistry and so on.

German-wasp

Digital Dossier

Research posts

Each of the 41 intriguing images in Picturing Science: Museum Scientists and Imaging Technologies tells a fascinating story about research or conservation projects. Here’s the last in a series of four snapshots.

New imaging technologies have revolutionized the age-old scientific tasks of observation and classification. And for James Carpenter, a curator in the Division of Invertebrate Zoology, they’ve opened up a new way of seeing.

Dr. Carpenter is tracing the ancestry of various wasps, which he does by examining the insects’ physical features to identify them and place them in their evolutionary context. His lab’s current project, funded by the National Science Foundation, is to reconstruct the phylogeny, or evolutionary history, of Vespinae, a subfamily of wasps consisting of hornets and yellowjackets.

Carpenter’s methods include photomontage—essentially digital photography—which allows him to stack images to focus on specific features. A head shot of a German wasp, part of the ongoing exhibition Picturing Science: Museum Scientists and Imaging Technologies now on view in the Akeley Gallery and curated by Mark Siddall, uses this technique to bring selected areas into sharp focus. These snapshots enable Carpenter to place the insect in the tree of life.

His lab also uses a variety of high-tech microscopes, including an environmental scanning electron microscope. This instrument highlights minuscule features without destroying the specimen, as often happened with earlier versions of the technology. Once Carpenter has the traits, he plugs the data into a computer program that synthesizes them at rapid speed.

A Universe from Nothing with Lawrence Krauss

Podcasts

The question “Why is there something rather than nothing?” has been asked for millennia by people curious about the universe’s origins. Today, exciting scientific advances provide new insight into this cosmological mystery. In this recent podcast, join Dr. Lawrence Krauss, professor of physics at Arizona State University, in a mind-bending trip back to the beginning of the beginning and the end of the end.

Hayden Planetarium Director Neil deGrasse Tyson introduces Dr. Krauss’s talk, which was recorded at the Museum on January 23, 2012.
