This is a lightly edited version of a keynote presentation I gave on 26 October 2022 at the Massachusetts Science Education Leadership Association meeting in Marlborough, MA. Thanks again to Liz Baker for inviting me, and the whole group for being such wonderful hosts. I really like the theme of this conference, “developing intelligent consumers of science.” I’m not normally a big fan of the term “consumers,” but in this case I think it makes sense.

When I started my journalism career 25 years ago, I had some major worries: how to expand my client list, how to keep paying the rent, whether I was even qualified to be doing this kind of work. Amid those existential concerns, seemingly minor issues of file organization didn’t even register. My workflow then was expedient, but not sustainable. I did all of my writing in a semi-legitimately acquired copy of Microsoft Word, saved the files on my Mac Powerbook in whatever folders seemed convenient at the time, and didn’t think the concept of an archive was relevant to my life.

In the process of a major overhaul of my blogs, the details of which I describe on my personal site, I revisited all of my old posts. I’ve been publishing these little essays online since 2006, and my very first science blogging post was a discussion of the then-new hypoallergenic cats from Allerca: Specifically, they’re cats that don’t express the gene for the most significant feline allergen protein. They are not clones, nor are they genetically modified in the same way many of our crops are these days, but they’re also not quite “natural.

Think of a disaster movie. Any disaster movie. Whatever the central threat, from Godzilla to malevolent extraterrestrials to climate catastrophe, there will be at least one scene full of people behaving at their worst: looting expensive luxuries from abandoned stores, smashing windows, screaming in panic, shooting at their neighbors. According to Hollywood, society is just one bad event away from near-total collapse, unleashing the Hobbesian wolves of our worst impulses and setting everyone against everyone else.

A few days ago, the World Health Organization caused a stir by saying that antibody tests may not indicate whether someone is immune from SARS-CoV-2. This led to some understandable confusion, and WHO spokespeople have subsequently walked the comments back a bit. While the messaging might’ve been handled better, the public health experts at the WHO were trying to make a very important point. Several prominent politicians have advanced the idea of issuing “immunity passports” to people who’ve recovered from SARS-CoV-2 infection.

On a blustery day in mid-December, TWiV co-host Vincent Racaniello and I, along with friend-of-the-show Islam Hussein, visited the picturesque campus of the Tufts University School of Veterinary Medicine in Grafton, MA. Our primary job there was to record an episode of TWiV in front of a live audience, featuring Tufts researcher Jon Runstadler and members of his lab. You can check out that episode now on the TWiV site. Before the recording session, though, we got to tour New England’s only veterinary school, which occupies the former site of a state mental hospital.

In the November 1943 issue of the journal Genetics, Salvador Luria and Max Delbrück settled a long-running but arcane debate among bacteriologists. The original paper is freely downloadable, and is an amazing document to read today. There’s a delightful innocence in the simplicity of the experimental design, the lengthy explication of the theory behind the work, and the humbleness of the authors’ conclusions. There is no hint that the paper is describing the dawn of molecular biology, a field that would revolutionize humanity’s relationship with nature in ways that are still unfolding 75 years later.

Which contains more information: a five-minute video or a five-page document? As anyone who’s had to pay for excess cellular bandwidth knows, the video contains far more raw data than the text file. That doesn’t mean it has more information, though. What if the video shows someone reading a Dr. Seuss book aloud? Most of the raw data in the video would just be a binary encoding of the speaker’s picture, and a tiny bit of motion around their mouth.

The first time it happened was a hot August day in Maryland, the kind where the nicotine-saturated air inside the tiny, heavily air-conditioned house seemed to vie with the humidity and traffic haze outside, each competing to be more noxious than the other. Late in the afternoon, as I left for my night shift summer job, the steamy transition zone at the front door hit me with a silent thud. Sweat was already starting to bead on my back as I rolled down the windows in my Datsun.

For a modern reader, the most surprising thing about the Galàpagos Islands chapter in Charles Darwin’s Voyage of the Beagle is probably its brevity. Darwin describes the apparently recent volcanic origin of the place, runs through a quick list of its notable species, includes a figure of some finches’ beaks, and then departs for Tahiti. His entire visit to the islands lasted only five weeks, during a voyage of nearly five years.

Modern parents have a fraught relationship with video games. The popular view, at least among many parents I’ve talked to, is that these games are harmful and that we’re supposed to feel guilty about letting our children play them. High-profile violent titles like the Grand Theft Auto series feed this perception, even though those games are clearly identified as being for adults only. Not everyone subscribes to the “video games are a barely tolerable evil” view, though.

I follow news about the science job market pretty closely, but perhaps the most reliable indicator I have of it isn’t in my RSS folder or Twitter feed. It’s my inbox. When graduate students and postdocs start to think their future is especially bleak, I start getting more notes from them asking about my choice of an “alternative” career. Many scientists have the naive impression that anyone with a PhD and a laptop can just take up science writing and make a decent living freelancing.
