Your Daily Time Machine

For me, geography is a time machine. The shape of the land sets the dials. Artifacts are keys. A few days ago I was watching for mammoth hunters out a train window. Climbing through the Rocky Mountains on the California Zephyr, I looked for spear bearers in the bony canyons and pine woods along the […]

Snark Week: The Wrath of the Sloth

If there’s a landmass that has them, get off of it now. As you’ll learn in this blog post, the last thing you want to do is find yourself trapped in a confined space with sloths, and I consider a continent a confined space. For starters, the sloth is the only animal listed as one […]

The Dragons’ Third Stir: the Next Bigge One

In keeping with the brave tradition of gullible, single-source reporting, here’s an astounding science news report.  It ran in the News and Views section of the prestigious journal, Nature, a couple weeks ago, I don’t know how I missed it, and it surely deserved more than the brief flurry of attention it got on Twitter.  […]

Redux: The Beginning of the End of Science

Some things never change. And sometimes the things that never change still somehow change for the worse. This post originally ran on January 5, 2011—an anti-science era that now seems almost quaint. Those were the days! I blame David Letterman. Less than a month before the 2000 U.S. Presidential election, one of the guests on his show was the governor of Texas, George W. Bush. […]

Ye Olde Scientific Writing

A few weeks ago, biologist Stephen Heard blogged about beauty in scientific writing. Among his examples, he cited an elegant explanation of quantum mechanics research and a playful description of a snake surveying a “disconsolate line” of frogs. More details can be found in Heard’s paper on the subject, which calls for scientists to strive […]

Hard Times in the Younger Dryas

This time last year, most of North America was buried in an unusual cold period. The jet stream had hemorrhaged in early January and the Polar Vortex that usually sits atop the hemisphere like a halo came pouring down. Known as the 2014 North American Cold Wave, temperatures plummeted, particularly in the Northeast and Upper […]

Gender in the Paleolithic

Camped with seven adults and five children on the south-central coast of Alaska, I was doing a little writing experiment. I had been following possible Paleolithic routes, taking off with adventurers across glaciers and mountains to get a sense of living and traveling in the same landscapes people faced tens of thousands of years ago. […]

Holiday Redux: The Ceremonial Stone

LWON is celebrating the holidays by re-running some of our favorite posts. This post originally appeared in slightly different form in July 2014. Sarah dipped her fingers in a red mineral paint and lifted them to her face. She put streaks above her cheekbones and up her chin, her design standing out against a backdrop […]
