Bracing: A military brat remembers 9/11/01

It’s a blue sky day and I’m looking out on an ocean of rolling green hills. All is calm, until suddenly I hear a  jet approaching from behind. The moment I sense the plane, I know that it is going to crash. I brace myself for the inevitable. The plane is careening toward the ground. […]

A botched battle in the vaccine safety wars

Doctors and scientists have lost yet another battle in the war over vaccines. On 25 August, the US Institute of Medicine released a report on the “adverse events” of eight childhood vaccines. The report summarized the exhaustive evidence on the possible negative health consequences of eight vaccines recommended for children, including the vaccines that prevent […]

What’s in a Name

The best thing that ever happened to the Big Bang is its name. For scientists, the acceptance of a scientific concept depends on its explanation of existing data, its prediction of observable phenomena, the observation of those phenomena, and the duplication of those results. But for non-scientists—well, for scientists, too—the popularity of a concept can come […]

Found Photos

I don’t know where you’re sitting right now, but do me a favor: zoom out to a space shuttle’s eye-view of your spot on the blue marble. Now spin the globe until you’re looking at exactly the opposite side. If you were here with me in London, our antipodal opposite would be (approximately) New Zealand. […]

An Arctic Land without Its Top Predator

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 […]

Dose Response

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 […]

My mother, on the bleeding edge of health care reform

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 […]

On anglerfish, scrub jays, and the menageries of childhood

The anglerfish was the iconic animal of my childhood. This eerie creature lives miles under the ocean’s surface and – as you probably know, if you were ever an animal-obsessed kid like me – dangles a fleshy, glow-in-the dark “bait” in front of its monstrous jaws. The dangling bait attracts prey and gives the animal […]
