An Arctic Land without Its Top Predator

By: | August 19, 2011

I’d just sat down when the first carver approached me. It was my second evening in Iqaluit on southern Baffin Island, 2000 kilometers north of Ottawa, and all around me well-heeled bureaucrats were tucking into Arctic char and steak. But the carver, a small weathered-looking Inuk, skirted them and made a beeline toward me. In his calloused hands, he held out a small sculpture for sale. It was a bear–a polar bear carved exquisitely from hard green serpentinite. With its long neck stretched and its head lifted, the carved bear tasted the air. Its maker, Jutai Noah, knew his subject intimately.

As it happened, I had just come back from a nine-day stay in a remote field camp on southern Baffin Island, and I’d just heard a lot about polar bears. Baffin forms a large part of the Canadian Arctic territory of Nunavut, and Nunavut is home, I’m told, to the largest population of polar bears in the world, as many as 15,000 of these large carnivores. But opinions vary wildly on how these legendary bears are doing in Nunavut these days. Continue reading →

Dose Response

By: | August 18, 2011

The college year in Japan starts in October, so in the fall of 1999 I had an extra month of summer vacation. It was going to be tough committing to a year in such a different place, while navigating a long-distance relationship with my boyfriend in Toronto, but life is for adventure. I arrived at Kansai International Airport in the last week of September, planning to take a week’s diversion to catch up with my friend Ian, who had taken a job teaching English in a small town in Fukushima Prefecture, roughly 75 miles (120 km) North-East of Tokyo. After that, I would head down to my new home in Ohbaku – a suburb of Kyoto – for my stint as a foreign student at Kyoto University, or Kyodai, as it’s known locally.

I was impressed that the local school had provided Ian and his girlfriend an entire house, with traditional tatami floors and sliding paper doors. It seemed like such a grown-up way to live, especially after our previous haunt at the university residence back in Canada. I happily settled in for the first night in my new country.

The next morning, 30 miles (50km) away, Hisashi Ouchi, Masato Shinohara and Yutaka Yokokawa were preparing a small batch of uranium dioxide fuel for a nuclear reactor, and they were under considerable time pressure. They opted for 10-litre stainless steel buckets rather than a dissolving tank, and then they poured their mixture, including about 16 kg of enriched uranium, directly into a precipitation tank, rather than the buffer tank designed to preclude the onset of criticality. Midway through pouring the seventh bucket, Cherenkov radiation flashed a brilliant blue, illuminating the workers, one leaning over the edge of the tank, another holding a pouring filter.

Science Metaphors (cont.): Resonance

By: | August 17, 2011

My mother was an old lady, she’d lived a good and useful life, and she died a year and ten days ago.  I hadn’t been keeping track of her death’s anniversary but I didn’t need to; I only had to figure out why I was walking around feeling, for no good reason, sad.  One of my cousins wrote to me, “I’m sorry you are sad, Annie. Thursday my new couch was delivered. I cried as my old one left – apparently I had an undiscovered attachment to it.”  My cousin recently moved to a new house with a new love; the old couch was from her old life, years ago, when her husband had died.  Sad in early August?  Crying over couches? Really? Science, as it often does, has a nice metaphor: resonance. Continue reading →

Abstruse Goose: A Brief History of Us

By: | August 16, 2011

AG’s sneaky caption this time is “. . . we are the universe made manifest, trying to figure itself out. — Delenn or Carl Sagan.”  It’s apparently a quote from Delenn who is apparently some scifi character who says portentous things.  Carl Sagan was real; also said portentous things; and undoubtedly said something like that, probably in a book called The Pale Blue Dot when he talked about the anthropic principle.

I’m fond of the anthropic principle because I published my first feature on it.  But it’s an Alice-in-Wonderland rabbit hole of an idea.  In its simplest form, it says that of all the possible ways the universe could have evolved, it must have taken the path that ended in us.  As astrophysicist, David Hogg, says, “No duh.”  Theorists use it to understand how the universe began:  the infant universe couldn’t have had, say, a gravitational force so small that we now wouldn’t stick to the earth.

Its more complex forms — even the ones that are more scientific than philosophical, let alone religious — just make my head hurt.  I’m steadfastly avoiding the the websites of the Wonderland.  I’m not even going to link to them.  You can google them if you like, but I don’t recommend it.  Ok, if you really have to, then here.  But don’t come complaining to me afterward.

My mother, on the bleeding edge of health care reform

By: | August 15, 2011

Among my fondest childhood memories are the hours my family spent discussing B cells and T cells while cruising the highways on our family car camping trips.

My mother, Irene Check, is a scientist; both she and my father got their doctoral degrees in microbiology, and my mother has a specialty in immunology – the study of the body’s defense against disease. What I remember most from our childhood conversations is my mom’s excitement about science: B and T cells are the main types of cells that do the work in the human immune system, but when my mom talked about them, they sounded like more than mere cells; they sounded like superheroes.

These days, however, my mom is a lot more than a scientist: she works on the front lines of health care reform. My mom directs an immunology laboratory in a hospital, which means that she runs tests to try to diagnose what’s wrong with patients’ immune systems. And while her love of science is what got her there, she now spends as much of her time cutting costs and trying to prepare for health care reform as she does using her scientific knowledge to help sick people.

Guest Post: Stranger on the Porch

By: | August 12, 2011

Last week my little black dog wandered off into the sloping hillside behind our Colorado home. Fifteen years old, deaf and suffering from congestive heart failure, she appeared to have succumbed to some primordial call to return to the wilderness to die.

She didn’t have far to go. My husband and I live in the foothills of the Rockies, at the quintessential intersection of wildland and suburban living. Houses and ponderosa pines alternately dot the rolling lots; ravines provide the perfect corridors for critters to journey down from higher elevations.

When we bought the house last year, one of the first discoveries we made on poking through local maps was that we were smack-dab in the middle of the local “summer bear concentration.” Next we read David Baron’s chilling The Beast in the Garden, about a mountain lion that in 1991 had killed and eaten an 18-year-old male athlete who was out jogging after a pepperoni pizza lunch. Within view of an interstate highway. Not too many miles from our new house.

Yet over time, we never saw a bear other than its scat or the occasional fur tuft on the barbed-wire fence. Cougars made not a single appearance. One may have made it from the Black Hills to Connecticut recently, but none have figured out how to parse the few miles from the high country to our back yard — at least while we were watching.

What we do, have, though, are foxes. Continue reading →

The Last Word on Nothing Jr. Edition, Part Two

By: | August 11, 2011

Last month, I recommended a few children’s books that I thought reflected the curious, adventurous, and humble scientific spirit of The Last Word on Nothing. Friends and readers have since added their favorite titles to the list — thank you! May these books bring all of you, and the young explorers in your lives, some late-summer reading pleasure.

A Log’s Life by Wendy Pfeffer, recommended by science journalist Jill Adams.

Bats at the Beach by Brian Lies, recommended by Colorado horsewoman and bon vivant Marla Bear Bishop.

The Magic School Bus series, recommended by science journalist Siri Carpenter and by Kim Todd (author of the terrific grownup science books Chrysalis and Tinkering with Eden).

Correcting Hollywood Science: Rise of the Planet of the Apes Edition

By: | August 10, 2011

I don’t have a problem with screenwriters fudging scientific truths as long as they: are internally consistent with their made-up science; and manipulate the facts in the name of telling a good story.

Rise of the Planet of the Apes, which came out on Friday, follows the first rule and tries to follow the second (more on that later), so I’m not upset that it gets a few things wrong about gene therapy. Still, I feel it’s my duty to tell you what was not quite right, and describe a few real advances in the field.
