The Stuff of Hot

Late Saturday evening, I was cutting jalapeños for the salsa for the next day’s barbeque party. I had a few other things on my mind — like my bean salad, and cleaning the bathroom, and figuring out what to write for this post — and so I forgot the lesson learned the last time I […]

My Coffee Problem

On Friday I woke up too early with a splitting headache and chest pain. This was alarming. In the shower, I tried to come up with a list of plausible explanations, but my mind found only one: the four cups of coffee I drank the day before. I wondered, is this how a heart attack […]

Guest Post: Bottle Insouciance

Are scientists who work with living organisms less germ phobic than civilians? When a science-writing colleague (okay: LWON’s own Ann Finkbeiner) apologized to an infectious disease specialist for giving him an insufficiently rinsed coffee cup, he responded, “Nothing in there I’m worried about.” I once watched a microbiologist cut her bagel with a butter knife […]

The economics of extinction, one tuna at a time

There are many ways to celebrate a new year—for me, it’s by becoming a “person of LWON” and joining some of my favorite science writers at this commodious corner of the web. For fishmongers at the massive Tsukiji market in central Tokyo, however, there’s no more festive way to ring in the New Year than […]

A New Year’s Diet: Mind Control

First week of January. Like everybody else in America, I’m on a diet. I’ve tried lots of diets over the years, and no matter how simple the particular rules — Fat is bad: stick to salads, whole grains and fruit! No no no, fat is good: lay off carbs, and eat lots of meat. Count […]

The Secrets in a Neanderthal’s Smile

Every time I see a new scientific paper bearing the name of Dolores Piperno, I sit up and pay very close attention. Piperno is a force to contend with in the world of archaeology, a researcher whose work is so unconventional and yet so rigorous that she has won over a small legion of skeptics […]

All I want for Christmas . . .

Each year my mother asks for my Christmas list. No, I’m not eight. I’m more than two decades older than that. Yet she still asks. And I still send one. (I also cc Santa just to be on the safe side.) This year, I’m inclined to ask for a kitchen thermometer. It’s not that I […]

Spuds, Spuds, Glorious Spuds

An old Yiddish joke: A poor yeshiva student visits a local family every evening for dinner. Each night, the family serves him potatoes: boiled potatoes, fried potatoes, potato soup, potato pancakes, potato kugel, and so on. After a week or two of this splendid spud-fest, the student asks his hosts to tell him the correct […]
