The Best Australian Science Writing 2012 (3 page)

Science continues to make amazing discoveries in a wide variety of fields. While new media provide almost instantaneous coverage of emerging events, and innovative ways to explain the basics of each discovery, the written word continues to provide the most detailed and in-depth descriptions of these discoveries, and I do not see that changing anytime soon. Enjoy reading
The Best of Australian Science 2012

Introduction:
Masters of the popular treatise

Elizabeth Finkel

‘I sometimes think that general and popular treatises are almost as important for the progress of science as original work,' opined Charles Darwin.

Indeed Darwin was a master of the popular treatise. His
On the Origin of Species
, published in 1859, was a best-seller. Take a look at his closing paragraph and you get an inkling why:

There is grandeur in this view of life, with its several powers, having been originally breathed by the creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.

Look at the passion and poetry of his writing.
Origin
was a 650-page tome meticulously detailing the evidence for evolution from examples gathered from the natural world and from domestic breeding. Yet the tome does not weigh you down. Neither his weighty knowledge nor the passage of two centuries presents
any barrier to the modern reader. Darwin's voice is vibrant, and astoundingly ‘present'.

Clear explanation, storytelling and passion are the pillars of great science writing. And in this anthology of Australian science writing you'll find many examples. Of course the stories selected here reflect my own inevitable quirks, interests and biases. So before we go on, let me give you a bit of the backstory to your editor.

I spent a decade in labs doing research in biochemistry and genetics and another couple writing about other people's research. I write for scientific audiences, mostly for the US magazine
Science
, and for lay audiences, mostly in the journal
COSMOS Magazine
, which I co-founded. I've also written two popular science books. Because of my association with
COSMOS
Magazine
and the inescapable fact that many Australian science writers are friends and colleagues, there is a potential ‘conflict of interest' in the selection of these stories. That's been addressed by vetting the stories with the advisory panel. I relied on my august advisors to detect any second-rate material that might have breached my subjective filter.

If I do have a bias, it is for muscular writing – the well-researched, well-told tale. Because like Darwin, I believe science writing has a hefty job to do. It must translate the often controversial and confronting science of the times, bringing it to a community that includes not only the curious layperson but also politicians and policymakers. As in Darwin's time, it is no trivial matter. Scientific ideas shape everything from understanding how we became
Homo sapiens
to passing laws on genetic privacy, gene patents, carbon taxes, cloning, GMOs, nanotechnology, germ warfare … to name just the ones kicking around my head at this very moment.

And of course science writers also have to titillate, to make people
want
to read their stories. Otherwise what's the point?
All the storyteller's crafts need to be put into play, just as Darwin instinctively knew to do.

Among the storytellers featured here, you'll hear two main types of voices. One is the journalistic voice, the traveller in an unknown country who reports earnestly and colourfully on their findings and who, as our proxy, asks and answers the questions we would like to ask: brave travellers such as Corey Butler enduring close encounters with creepy crawlies while tagging along on a wildlife inventory of a vast former South Australian cattle station, or Wendy Zukerman, who after encountering fornicating cockroaches in her midnight kitchen, explores the secret of their success. Or there's Ashley Hay taking us along for the ride in Cairns with a team who are releasing mozzies infected with
Wolbachia
bacteria. A gift from nature,
Wolbachia
, once lodged in its mozzie host, stops it from spreading dengue virus.

Leaving the very popular realm of creepy crawly science, Wilson da Silva delivers a thrilling eyewitness account of the launch of the space shuttle at Cape Canaveral. No one but da Silva could have authored this piece. It's a fulfilment of his life-long dream to witness a space shuttle launch. But it's tempered with pathos: this was the last launch. With Christine Kenneally, the CSI lab meets the stuff of legend. Ned Kelly's bones were lost in the dark mists of time, but the passage of one and a third centuries is no impediment to the modern DNA test. It nailed the long-lost bones, bringing Kelly to life once more.

Harrowing, but with deadly accuracy, the 2011 Hollywood blockbuster
Contagion
painted a picture of what a killer flu pandemic would be like. Nick Miller takes us behind the scenes to the real-world drama of battling viral pandemics. We get a closeup view of American virus hunter Ian Lipkin, who served as the model for one of the key characters in the movie.

Jo Chandler, brave soul that she is, travels to the Antarctic to experience climate science in the raw. For anyone jaded by climate
science, her insider's perspective – she is a senior writer for
The Age
– on the media's treatment of this science is galvanising. Freed from the constraints of the broadsheet we hear Chandler in full voice, setting the standard for long-form science journalism.

Richard Lovett takes us to Saturn's icy moon Enceladus, whose tantalising chemical signature was read for the first time by the Cassini space probe in 2005. It turns out Enceladus is the solar system's best candidate for finding alien life!

Adrian Hyland travels the still raw emotional landscape of Black Saturday, 7 February 2009, when the state of Victoria ignited into an inferno that claimed 173 lives. As any therapist will tell you, ‘analysis' is a key part of recovering from trauma. In this case Hyland does it though a scientific prism. Why is Australia the most fire-prone nation on Earth?

Fire yes, but earthquakes? Emma Young reveals that Australia – though not fractured by a tectonic plate – experiences far more than it should and scientists are not sure why. Part of the reason is that the capacious Indo-Australian plate on which Australia rides is colliding with the Eurasian, Philippines and Pacific plates to the northeast. Startlingly, another reason may be mining – perhaps it was a contributor to the level 5 quake that rocked Kalgoorlie in 2010?

The other voice, well represented here, is the authoritative voice of the scientist. He or she has a head start. Knowledge is theirs – and passion too; otherwise why would they put up with the poor pay and tyranny of incessant research grant deadlines? But do they have the storyteller's gift? Some do. And thanks to publications like
The Conversation
, more and more of their voices are spilling out of the labs. Take a look at the exuberant tone of Helen Maynard-Casely, writing about the alien life that might be
discovered in Antarctica's Lake Vostok. Its icy 4km crust has just been breached after 20 years of drilling! Below lies an environment not unlike the ocean beneath the icy crust of Europa – one of the ‘lover' moons of Jupiter. If life is indeed discovered in Lake Vostok, it will cue exobiologists for what to search for on Europa. Or join Jonathan Carroll, trying to make sense of the faster-than-light neutrinos reported this year. It was the most extraordinary science story of the year! And it is intriguing to hear his perspective. How does a working physicist respond when one of the pillars of his discipline is rocked? Then there is Peter McAllister, having some fun with his anthropology. He ponders (as I must confess I have) what it was like in the days when men were men. How well-endowed, for instance, were the rowers of the Ancient Greek triremes? With superhuman strength, it seems. Modern athletes can manage 6 knots for an hour; the Athenians could keep up 7–8 knots for a 12 hour sea crossing!

In a more serious tone we hear from Frank Bowden, an infectious diseases physician who chose a really bad time for his sabbatical: Australia's 2009 H1N1 influenza outbreak. While his wife – an infection control practitioner – battled at the frontline, Bowden stayed at home to observe the epidemic at arm's length. His report paints an unsettling picture. In the aftermath, a common criticism was that institutions over-reacted and that millions of dollars were wasted in unused vaccines. Bowden reminds us that 722 people had to be admitted to intensive care and 103 of them died, including seven pregnant women and seven children. If the flu strain had been just a little more virulent (and it was impossible to predict at the time) those dollars would be ‘petty cash'.

Which brings us to yet another type of voice: the science writer on a mission. The pen is powerful. And some of the voices in this anthology – both scientific and journalistic – are using it for all it's worth.

Journalists Craig Cormick and Cassandra Wilkinson take on the irrational element in their diatribes. Cormick explores why it is that clever people believe in silly things such as, for instance, not vaccinating their children. Dismayingly, his analysis seems to affirm Jonathan Swift's aphorism: ‘You can't reason someone out of something they didn't reason themselves into.' Vaccination refusers are likely to spend lots of time educating themselves on the internet – but by reading material that supports their position. Feisty Cassandra Wilkinson pulls no punches in her argument that the public health dollar should not be squandered on treatments with no proven benefit, like homeopathy. Pharmacologist Ian Musgrave explains why: homeopathy, a relic of mediaeval alchemy, is a practice at odds with the laws of physics and chemistry.

But mainstream medicine is not perfect either.

GP Pamela Douglas admits us into her world for a closeup view of how medicine is susceptible to fashions that are
not
based on proven effectiveness, safety or common sense. Her case study is ‘infant reflux', or colic. She observes how doctors went from offering barley water and reassuring mums that their babies would outgrow it, to the widespread treatment of newborns with drugs in the 1990s – a practice that has since been abandoned. Tim Bohane, a Sydney-based paediatric gastroenterologist, commented, ‘I would love all medical students, and indeed budding paediatric gastroenterologists, to digest this article.'

Oncologist Ranjana Srivastava also takes us into her consulting room. Textbooks do not help her counsel her dying patients. Their journeys are unique and uniquely challenging for the young doctor. But writing does help. Srivastava writes because she is ‘unable to close the door to the mind'.

In a more light-hearted tone, evolutionary biologist Michael Kasumovic goes on the warpath in defence of video games. Tired of the reigning wisdom that video games are likely to leave
a child with the sensory and moral development of a mole rat, he surveys the scientific literature to show that on the contrary, gamers are
not
more likely to become sociopaths – many of them are college professors, bankers … and even evolutionary biologists.

Rob Brooks, another evolutionary biologist, has a more serious mission in mind: saving the planet. He is terrified by the birth of the seven billionth person – an event that happened on 30 October 2011. How will we sustain the growing population when over a billion already live on less than a dollar a day? Empower women, says Brooks. Give them access to contraception, education and employment and they will have fewer, bettertended children.

William Laurance, a conservation biologist, is on a mission to save the planet's rainforests. Not only are they home to endangered species like orangutans and tree kangaroos; they also keep the planet cool by locking up carbon and exhaling water vapour to make clouds. He champions economic instruments like REDD (Reducing Emissions from Deforestation and forest Degradation) as a way to trade forests for carbon credits. True, such instruments are too often rorted, but they can be policed through satellite surveillance and the upside is huge. For developing nations, rainforests could become even more valuable than the farmland that's replacing them.

Journalist Julian Cribb wields his pen for the planet in a way that might have been inspired by Gandhi's admonition: ‘Be the change you want to see in the world.' Cribb pens a picture of Australia's golden age in 2050 when science and sustainability are the driving forces behind a thriving economy, agriculture, medicine and the arts.

Astrophysicist Matthew Bailes makes it his mission to expose the fickleness of the media. After discovering a new ‘diamond' planet last year, Bailes suddenly became a media darling: the
journalists were wowed by the idea of a diamond planet. But he reflects that when it comes to climate science, the sexier spin is to cast doubt on the findings. Bailes' story certainly struck a chord. It's had over 69,000 readers, 2600 tweets, and been ‘liked' 6700 times on Facebook!
