Death in the Line of Treasure Hunting

A treasure hunter recently died near the Rio Grande in New Mexico. His body turned up in the backcountry after he was reported missing. This is the second death of a treasure hunter looking for an ornate bronze chest said to be hidden somewhere between Santa Fe and Canada by multi-millionaire artifact collector Forrest Fenn. […]

Doom and the dogmometer

One way to understand a really big problem is to break it down into more manageable parts. That’s why scientists use specific, smaller systems to help them grasp the overall health of the planet. The Arctic, for example, is regarded as a bellwether for the catastrophes of climate change that will soon afflict us all, […]

Redux: The Unknown Grizzly

This post originally appeared March 7, 2013. In the mail yesterday I received a grizzly bear skull from an acquaintance and taxidermist in Soldotna, Alaska. Expertly cleaned down to chalk-white bone and glistening, thumb-sized canines, it was the size and general shape of a football, and as smooth as sanded wood. My friend had apologized […]

Mrs. Whitcher and the Renegade Numbers

In 1938 a wallet manufacturer called the E.H. Ferree company had a genius idea: to show people just how well cards would fit in the wallet, by using a placeholder. This was before credit cards and before many drivers licenses were small enough to fit into wallets. So the thing they used to showcase the […]

Where is here; here is where

Isaiah grins at me across the dining room table and more than 1,000 miles. In my nephew’s small, pale hand is an outsized Crayola marker, to match the pencil in my more gnarled fingers. We both lean over rectangles of paper—his in Colorado, mine in Oregon, now occupying the same virtual space, thanks to a […]

My Liver’s Bloody Buddy

Periodically, I get an MRI to confirm that all is well with my internal organs. It’s because at one point some years ago all was not well. As a result of my bodily dysfunction, I now have no spleen, a tailless pancreas, plus ulcerative colitis and weird chronic pain and the beginnings of arthritis in […]

The Quaking Giant

On the western edge of the Colorado Plateau, in the mountains of central Utah, is a tree that weighs an estimated 13 million pounds—as much as three giant sequoias, or 55 blue whales, or 10,000 grizzly bears. (Hey, I just thought you might like to imagine a pile of 10,000 bears.) This tree is the […]

Truth + Beauty

A couple of Harvard astronomers just wrote an essay in a new journal called Nature Astronomy.  That’s not the most riveting opening sentence you’ve ever read; I apologize. But the essay was odd, a kind of rumination-with-examples about how things in astronomy on vastly different scales nevertheless have similar structures.  That is, electrons orbit atomic […]
