ROAM: an interview with Hillary Rosner

By: | October 15, 2025

Hillary Rosner is a science journalist and editor who teaches journalism at the University of Colorado, Boulder. She is also a friend and fellow member of Scilance, a network of 30+ science writers that has been meeting up online for 20 years. Over the years, I’ve loved following Hillary’s thoughtful, adventurous reporting on wildlife conservation, whether she’s writing about orangutans in Borneo or the Devils Hole pupfish in the Mojave Desert. Now, she’s written a wonderful book, which was published yesterday by Patagonia. It’s called Roam: Wild Animals and the Race to Repair Our Fractured World.

In Roam, Hillary writes about conversation projects around the world that are studying how wild creatures move across landscapes and working to support species by reconnecting fragmented habitat. I was lucky enough to talk with Hillary last week. Here’s our (lightly edited) conversation about Roam.

The Black Locust

By: | October 13, 2025

Our neighbors of ten years moved away about a month ago. They were an older couple; L., the husband, was the one we interacted with the most. He was a commercial contractor and drove a big black pickup, but he also made sure to let my wife and me know he had never once voted for Trump. This is Seattle, after all.

As neighbors we were friendly but not overly so. (Again, Seattle.) L. was jocular in a Hail-Fellow-Well-Met kind of way, and we enjoyed occasional chitchat over our shared fence. Once when that fence needed to be replaced, L. was able to leverage his contacts and get us all a discount. For that I was grateful.

This placid cordialness would have been the defining feature of our relationship but for an incident a couple of years ago. One spring afternoon I was doing some yard work when L. came outside and leaned over the fence. “Hey, Eric, got a question for ya,” he said. “What do you think of your tree here?” He gestured to the tree I was at that moment standing under.

I looked up and considered the tree. It was about forty feet tall. Thin. Small green leaves and white blossoms bedecked its branches.

“I don’t know,” I said. “It’s nice enough.”

L. nodded. “Have you ever thought about cutting it down?”

I smile-grimaced in a way I do when I’m not sure how to respond. “Have I thought about cutting it down?” I said. “No. Why?”

L. explained his thinking. After the tree was done blossoming, its petals fluttered down into his backyard. They were a pain to sweep up. They also had a powerful fragrance, and his wife did not like the way they smelled. So if I didn’t have strong feelings about the tree, it wouldn’t be a huge deal just to, you know, get rid of it.

“Think about it,” he said, and went back inside.

Did You Know

By: | October 10, 2025

The Moon is closer during a supermoon and you will be able to tell, because it looks so much bigger and brighter, but your photos of it will still suck.
You can still send me the photos you took, and I will appreciate them, as well as appreciate that you thought of me when you saw the Moon. No, I am not tired of talking about it.

It is a long road that has no turning.

If you hit glue three Lego bricks along the side of your desk, and then attach three Lego mini figures on them, they can hold your charging cords and you can have Darth Vader or whoever holding your iPhone charger. This will be so much more work than just letting the chargers fall to the floor, and you will need to make a video about it to put on Instagram so you can tell people about it and hope to justify the time and effort you expended. It will not be worth it.

You don’t need a bread basket. You can just put your bread in the pantry, with the peanut butter and other ingredients. It will be ok.

If you buy a seasonal bath mat your kids picked out, the citrus fruits motif with the phrase “welcome summer” will feel weird by the end of September.

Enough is as good as a feast.

If you add a bunch of unnecessary stuff to your Amazon cart, you can check the prices each morning instead of reading the headlines, and feel a little better but somehow also a little worse about the course of your day.

The sun is important to your wellbeing. You should do whatever you can to see it as often as possible, and ideally to feel it on your skin at least once a day. This is hard to achieve when you are sad, but it is even more important then.

Health is better than wealth.

If you go for a walk, you will feel better, but you will not feel the truth of this until after the walk has begun. The improved mood that results from a walk can happen or not happen depending on whether you are wearing your shoes. This superposition of emotional states is a fact of quantum physics.

The road to hell is paved with slick grease sold by absolutely idiotic ill-intentioned liars, and many things are sliding down it, even now, but we have ways to stop this slide, which not enough of us are using. We must stop the paving and slickening of the road to hell by using every tool and skill at our disposal.

Vaccines prevent communicable diseases.

No matter how long the day, the evening comes.

The Stubborness of Women

By: | October 8, 2025

This post first appeared in November 2023.

For reasons I didn’t fully understand myself (marriage? the cat? surely someone or something else was to blame), I was feeling more than usually lazy, or maybe just unwilling to tolerate the discomfort of writing. It felt like a dangerous malaise, and the only remedy I could think of was to try to soak up some other people’s bravery. So a couple of months ago, I asked our Ann for her recommendations of favorite essayists.

She recommended Montaigne: “I haven’t read him in a while but I loved him,” she wrote. “He was so smart and funny and open.” I trundled off to a used bookstore and picked up a copy of The Essays: A Selection, translated by M.A. Screech. I’m only about three quarters of the way through the book, but I’ve been taking notes and sending them to Ann as I go. She suggested they might make a decent post, strung together. So, in the provisional spirit of Montaigne, I share them with you, dear LWON readers.

To philosophize is to learn how to die

I read this essay while waiting for a big vegetable lasagna to bake. I was in the middle of Montaigne’s exhaustive list of ways to die (killed by a bump from a pig!) and his instructions to continuously keep death at the forefront of our minds, when the timer beeped.

I went to pull the lasagna out and dumped the whole thing upside down onto the oven door, barely missing my feet. After screaming for help, then scooping the charred noodles back into the dish, I went back to the couch and read the following: “I want death to find me planting my cabbages, neither worrying about it nor the unfinished gardening.” The lasagna looked terrible but tasted great.

Lions and Tigers and Bears, Oh My!

By: | October 6, 2025

Our little farm is nestled in a pinyon juniper habitat that we share with lots of other creatures. Often enough, we encounter these animals close up. Sightings of foxes, coyotes, deer, elk and turkeys are so commonplace as to have become almost (but not quite) uninteresting.

Other creatures we see mostly by the signs they leave behind — paw prints, scat, feathers, fur, or partially eaten prey.  Sometimes they invade our garden, compost pile or orchard. One year, a bear climbed up into a young Honeycrisp tree that was loaded with apples and nearly destroyed it while devouring all the fruit. 

We have a game camera near the back of our property where we can observe creatures coming and going. It’s been a busy summer on the game cam. 

Here’s our neighborhood bear.

A mountain lion has also been hanging around. We’ve been seeing him a lot on the game cam, though never face-to-face (and I’m ok with that).

Oh, and the tigers! Ok, tiger striped cats, but they think they’re tigers. Sometime this summer a mamma cat started hanging around our winery. They were hungry, so I gave in and began feeding her and her five kittens — two black, one gray and two tiger striped tabbies. We have managed to trap all but one of them (still working on it!) to vaccinate and spay or neuter, which I’ve learned is no easy task. 

My Hard-Won, Useless Knowledge

By: | October 3, 2025
Hand holding up train ticket with platform and tracks in background

Let me share a travel tip with you.

You will not use it.

The tip: When you come home from visiting a country with different currency from your own – say, in Europe – hang onto your change. You could spend all your centimes or marks or groschen on airport chocolates, to lighten your wallet. But someday, maybe you’ll come back and you’ll be standing, bleary-eyed, at an airport public transit hub, in front of a ticket machine that only takes coins, and you’ll be a lot happier if you have some of those coins with you.

You see why you won’t be using this advice? First of all, those currencies don’t exist. But much more galling, to me: those damn ticket machines now take my American credit cards. In some places I can even tap my credit card when I get on. I may never have to keep track of a charming foreign subway ticket again. Last year I went to the UK for a week and never even felt the need to get cash.

I used to be an expert of Western European transit ticket buying. What am I supposed to do with my obsolete knowledge now?

It isn’t just tickets. I have a lot of knowledge that I painstakingly acquired and can no longer use. Like knowing how to get to places. I love maps! I know all the good routes in my hometown! But, over the last 20 years, my expertise has been gradually usurped, first by Mapquest and then by various apps.

Even my language skills are losing their value. For a whole year of my life, in the previous century, I spent 20 hours a week in language class in southwestern Japan. A few years ago, I sat down with American friends in a cafe in the western reaches of Tokyo, picked up a menu, began to read out loud – this says black tea, this says green tea, this one has strawberries – and was shocked, even a little crestfallen, when one of them got out her phone, pointed it at the menu, and read it for herself. Google Translate trounced my weak reading skills.

My feelings about all of this increased convenience are complicated. I love when I go to an unfamiliar city and can ride public buses with ease, because my phone tells me where to stand and what number to look for. It’s not really fair that I got to spend a year in my 20s studying a language full-time; that’s an extremely high, expensive barrier to engaging with another society, and it’s nice that other people can do it more easily. And the other day I wanted to read some instructions in Japanese and, yeah, I whipped out my phone.

But, at the same time, acquiring these bodies of knowledge is part of what makes life great. Learning a new language is brain-melting, soul-enlarging. Learning your way around a town builds a mental map of surprises and one-way streets. Hoarding coins for next time means you have happy little envelopes and baggies of metal tucked away in a drawer, carrying hopes of future travels, for your children to find after you die.

Obviously I’m part of a long tradition of people complaining about technological change. The kids these days, they just go out and buy a shirt! In my day, we had to harvest the flax and weave it ourselves! And anyone who’s spent the last few decades chasing computer technology probably knows the feeling. My dad did the data analysis for his PhD with stacks of punch cards; no wonder he struggled to understand how to interact with an app. I still use keyboard shortcuts from an old version of Microsoft Word and live in mild dread of the day when my brain is too creaky to navigate the implants we’re using to order our sub-orbital rocket taxis or whatever.

I’m reminded of Our Tom’s essay In Praise of Crap Technology, in which he lovingly describes his $20 digital music player. Should I take inspiration from Tom? Boycott contactless credit cards in favor of pockets full of euros? Lug around my 4-pound Japanese-English Character Dictionary, just in case I need to decipher a sign? Maybe I should find a paper map of my area, if any still exist, and find my own route to a new destination, current traffic conditions be damned?

But these seem like really pointless protests. Maybe I should just sit back, play a game on my phone, and remember the glory days when I knew something useful.

–Hiring Manager, Esteemed Organization That Doesn’t Want You, You Loser

What does rejection do to the human brain? How about repeated rejections? Let’s say, four? Or 12? How about 29? It does something, I’ll bet.

As one of thousands recently torn from their jobs and tossed into a pit of talent, where truly good, skilled people are trying to claw their way back to employment without elbowing colleagues in the eye, I looked it up.

It’s a form of social rejection, this “thanks but no thanks” letter many of us keep receiving from potential employers. Evolution tells us to care about it: Social acceptance, in this case being told you are “good enough” (and better than the rest, in fact) to join a particular team, represents safety and access to resources. It makes sense that it would matter.

Apparently, there are “positive” aspects to rejection—it can motivate you to try harder, to reframe your thinking, to set aside your ego, to learn to be patient, yadda yadda. Sort of obvious things that are a little hard to take seriously right now. But make no mistake, social pain is real pain; scientists suggest the brain systems that underlie that ache of rejection likely co-opted the brain circuits supporting physical hurting. That means the two kinds of pain share activity in our somatosensory systems, and that intense social pain (e.g., the deep ache after a romantic breakup plus the crush of spying your ex on a hot date) may glom onto sensory-pain processing regions. It’s messy, this pain thing, and there’s a lot of crosstalk between ache and heartache, between “ouch” and “daaaaaaamn.”

Social pain reaches deep within us in other ways. A relatively new field called social genomics reminds us that the genome isn’t a fixed blueprint but a dynamic system that reacts to human experience. It’s known that negative social interactions can and do affect our health, not just the mental but the physical; more recently, scientists have discovered how our experiences as social beings can even meddle with our gene expression, by way of a host of biological and molecular mechanisms. The brain, the body, the genome…it’s a partnership for better or worse.

If you get rejected enough times, though, I’ve found you start to care less and the physical yearning for acceptance dulls a bit. Especially when you know you’re in good company, which I certainly am in this case, you learn to take the blame off your own shoulders. I like to think this shirking of responsibility gives our fragile egos a fighting chance for a comeback. And more important, that it keeps the message “I’m not good enough” from chipping away at our health and telling our genes what to do.

Male Rain

By: | September 29, 2025


In the Navajo vernacular, this time of year we often get what is called male rain, níłtsą́ bikąʼ. These are drenchers that come on strong and swift, rutting out driveways, turning the river a sudden brown, and they’re usually finished just as fast as they started. This happens when upwellings of heat from the ground collide with cool, moist skies. Other times of the year and in more stable conditions, you get what in Navajo is called female rain, níłtsą́ biʼáád, which falls soft and long, the kind of precipitation that saturates the ground and wets the roots of plants. I’d take either any day, but in the high summer into fall, male rain rules.

Driving a lonely two-lane home from Wyoming, I noticed a silver slash across the highway ahead. Wyoming was just as hot as Colorado, just as hot as about everywhere, and I saw no rain in its scattered clouds. Knife blades of virga reached toward the ground but didn’t make it all the way. As I drove closer to this line across the asphalt, slowing from 70, I could see the air three feet above it misted from exploding raindrops. It wasn’t only rain, it was a fierce rain, and it occupied a space that looked to be fifty feet wide at most, the highway dry to either side. I craned under my windshield and saw a faintest band of gray overhead where a slice of precipitation had fallen out of its cloud. The rain didn’t begin with a drop or two. It came all at once. I sped into a blinding downpour, double-fisted on the steering wheel, eyes dead ahead. My roof and hood sounded like a hail of pea gravel, windshield wipers throwing water everywhere. In another second I broke out the other side trailing a rooster tail of haze. The roar ceased and I kept driving into a dry, sunny day. That was the níłtsą́ bikąʼ, male rain.
