The Mark We Leave

Rounding a corner in Manhattan last week, I saw a handprint spray-painted on a wall. It was my hand. I had put it there last summer, my first and only piece of graffiti. It was nothing special, no artistic flair other than my five fingers. I had gloved my hand in plastic wrap and waved […]

Searching for the First Americans in the Smithsonian

In the quarter light of a few remaining bulbs in a decommissioned hall of the Smithsonian, Kirk Johnson, the museum director, pushed back drapes of clear plastic. The National Fossil Halls was being undressed for demolition, dioramas and murals half torn down, everything had to go. In his business outfit, a coat and tie and […]

“The Martian” and Ice Age Astronauts

Two nights ago I sat in a theater watching the film “The Martian.” I loved seeing a viable spacecraft making gravitational slingshots around planets while a stranded, potato-growing astronaut claimed himself the first colonist on Mars. What’s there not to love? Meanwhile, in my coat pocket I carried an object from an entirely different age […]

Seeing Through Time

In the bespangled Pioneer Saloon in Paisley, Oregon, hangs a picture on a wall of a fit, gray mustached archaeologist out in the field. Written in pen, the name at the bottom of the photo is Dr. Poop. Dennis Jenkins is his actual name, a senior archaeologist at the University of Oregon. Jenkins leads paleo digs in […]

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 […]

My Mom on the Bering Land Bridge

All this week Last Word on Nothing is geared toward Mother’s Day, which is next Sunday. Tell your mother you love her and share some of our posts, things are about to get maternal. Pictured above: my mother. I held her cold hands in mine, rubbing warmth into them as she crouched behind a rock […]

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.  […]
