Telling a Science Story

One of the things I do is help scientists describe their work to the public. Sometimes this means writing a press release or reading over an article someone has written for a publication. Whatever it is, my job is to find the most important parts of the story and bring them forward so that the scientist and the public (reporters, usually) can have a meaningful discussion about the work. That’s not always easy, since there are stark differences in the way scientists write up their work for their peers and the way they might tell their story to the public. You can chalk those differences up to the rigors of scientific publishing, where the methods of doing a science experiment are as an important part of the story as the results.

Every discipline in science has its jargon, its ways of communicating among the participants. For example, if you go to the doctor and have an examination of your right side above your waistline, your doctor might write up that the examination centered on the abdominal RUQ. Jargon, to be sure, but it’s a shorthand that describes exactly what was examined. Or, let’s say you go to a talk about the early universe, as given by one astronomer to a group of colleagues. You might hear the following: “We’re using long-period gamma-ray bursts as a probe of the intergalactic medium neutral fraction at z=6.3.”

Translated, that means that they’re looking for long-period gamma-ray bursts (longer than a few seconds, typically), which scientists think happen when a huge star explodes and emits a jet, or when a white dwarf star merges with either a neutron star or a black hole. The action emits a huge burst of radiation, which speeds across the universe. As it goes along, it passes through clouds of gas, clouds of gas and dust, and through clusters and possibly other galaxies. As it does, that radiation (light) is absorbed by whatever is in the way. You can see that absorption when you study the light with special instruments called spectrographs. The results tell you the chemical makeup of any clouds of cold gas, or gas and dust in the space between galaxies back in the early universe (more than about 9 billion years ago). So, in that one sentence, the scientist says a lot, but it’s buried in specialized language.

In a science paper, the typical form is to describe (briefly) a finding, and then go into details about how that finding was made (equipment, constraints, etc.), and then go into the details of the finding. Often this means that the “news” of a paper is buried IN the paper, and not up in the first few sentences, as you’d see in a newspaper story. This is perfectly normal and nothing to be worried about—unless you’re also trying to explain the “newsworthy” part of a science discovery to the public. Then you have to find the “meat” of the story, and lead with it in the first few sentences. So, a story about the gamma-ray bursters might read like this if you saw it in the paper: “Scientists at Gemini Observatory are using the 8-meter telescope to peer back about 9 billion years to study bright flashes of light called gamma-ray bursters. The light, which passes through clouds of gas and dust on its way across the universe, can tell astronomers the makeup of that gas and dust, as well as how quickly it’s moving.”

That’s my job—to identify the news in a story and help tell that story. I might do it for a press release or a newspaper article or a magazine article, or (my favorite) for a planetarium show or documentary.

So, a few weeks ago I was talking to a scientist who studies the effects of space weather on our communications systems. Spaceweather (which you can learn more about here, and here, and most especially here) is basically a catch-all term for interactions between material that has been belched out from the Sun and our planet’s magnetic field and upper atmosphere. Auroral displays (northern and southern lights) are the most obvious manifestation of space weather that we can see.

There’s another side to space weather, however. A strong event can knock out telecommunications systems, power grids, and GPS satellite service. This last is important because we depend on GPS timing signals for an incredible number of things in our daily lives.

So, back to the scientist. She was asked to give a presentation at last week’s Spaceweather Enterprise Forum in Washington, D.C. She came to me for advice on how to identify some strong talking points for her presentation. So, we set to work on her statement. The science is very compelling, very straightforward: spaceweather can harm GPS systems. We need to know that and construct backup systems as well as harden the systems we have. Otherwise a strong solar burst could knock out more than just communications. I asked her for some examples of what GPS effects are in our daily lives. She mentioned a few, including one I hadn’t thought about: financial transactions. Bank transfers depend on accurate timing from GPS. So, I said to her that this was a point that would grab people right in the wallet. To me it was a point that would grab the attention of bottom-liners in business as well as government. So, I suggested that she make that one of her talking points.

We quickly came up with a few more talking points, such as how we can’t predict when large solar outbursts are going to take place. We were totally surprised by one last December that partially shut down GPS systems for (as she put it) tens of minutes. That’s a long time in communications and financial circles.

We honed her statement down and off she went to the meeting. And, lo and behold, her statements got picked up by nearly every news agency in attendance. Even though she was the last speaker on the podium, she got maximum “sound bite” out of a simple truth: space weather can and does affect things on this planet. (If you’re interested in what she had to say, go here and click on the link for Anthea Coster of MIT’s Haystack Observatory. Heck, listen to all of them!)

It’s a lot of fun being a space writer and doing what I do. Sometimes it gets me in on a story before it hits the news!

Speeding Through the Universe

For those of you (family AND friends) who wonder what I do sometimes, this picture is where I spent some of my time the past few days. It’s an image of wakes created by supersonic-speed “bullets” of gas boring through a starbirth region in the Orion Nebula. It was taken at Gemini Observatory North on Mauna Kea in Hawai’i, using a laser guide star-equipped adaptive optics system to help remove the effects of atmospheric turbulence. (You can read more about this system here.)

I work with Gemini Observatory as a writer and I am the associate editor for their twice-a-year GeminiFocus magazine. When their public affairs office sent me this image last week, I started immediately working on some language for a press release, along with Peter Michaud (their Public Affairs Officer). It was a whirlwind of activity, involving the two of us, several scientists, and astronomerTravis Rector (University of Alaska at Fairbanks), who did the major work on the image. We worked on the language over the weekend and went through several iterations of the language. Finally the directors of the observatory gave their blessing on the version you can see here.

For me, the project entailed doing a little bit of a literature search to see just when these “bullets” were first discovered (1983, defined in 1992), and then figuring out how much of the science background was relevant to put in the story. Peter and I swapped several versions via email and chat, then sent the story on to one of the scientists (Tom Geballe) for a sanity check. Another scientist, Michael Burton of the University of New South Wales in Australia, had done some work on the bullets a few years back, and his advice was also thrown into the mix. In addition, we had Gemini astronomer Scott Fisher and Jean-Rene Roy, Deputy Director and Head of Science, look it over as well. (It’s always best to have as many eyes as possible look these things over before they go out.) By late yesterday (Wednesday, March 21), we had a version we could all live with. It went to the webmaster in Hilo, who posted the final version late last night.

It’s a lot of fun to work with these stories “behind the scenes” and talk with the people who are doing the research in the areas the Gemini images cover. Hope you enjoy the image and story!
