Hello, and welcome back.
My apologies for the long silence. The past few months have been wonderfully full, and more than a little overwhelming. At home, my older just finished middle school. It’s hard to believe that I’ll have a high schooler next year! At work the end of the semester brought an NIH grant application beginning the process of hiring a new lab manager, training our summer interns, conference travel, and all the usual juggling that comes with maintaining an academic research program.
And then there was… gestures broadly at science.
I attended a conference during what felt like an extraordinary week for research. Amid funding uncertainty, attacks on higher education and science in general, questions about public trust in science, wonderful ground-breaking, health-improving science was being shared. Yet in hushed conversations at every coffee break and dinner, we shared our concerns about our freedoms. Not just about our scientific funding or academic freedoms, but about our first amendment rights to free speech, our right to speak out about against the politicization of science. This left me thinking less about my science, and more about what it means to be a scientist right now.
Perhaps that's why I keep coming back to these essays. I've realized they're becoming something I never quite intended: they are my love letters to science. Not to science as a collection of facts, but to the process itself. To the curiosity, the uncertainty, the long history of discovery, and to the extraordinary people who devote their lives to understanding how the world works.
This issue reflects that. Each of these essays asks a different question, but they share a common thread: how scientific understanding is built, why it deserves our attention, and what our role is in carrying it forward. I'm grateful you're here. And I'm especially grateful when these pieces resonate with others who find themselves asking the same questions.

The Long Road to Scientific Consensus
How did we come to trust things we cannot directly observe? This became one of the most ambitious essays I've written so far, tracing more than two thousand years of scientific history, from Aristotle's theory of spontaneous generation to Louis Pasteur and the birth of germ theory.
This is a story about microbes, certainly. But more fundamentally it is a story about methods, evidence, and how scientific consensus slowly emerges over decades. This piece also made me think differently about today's conversations around vaccines, food safety, and public trust in science.

When Excellence Is No Longer Enough
For much of my career, I believed that doing careful, rigorous science was enough. That if we produced good evidence, it would eventually speak for itself. Increasingly, I'm not sure that's true. This essay reflects on the changing role of scientists, the growing importance of public engagement, and why communicating our work has become part of the work itself.

All At Once: This Past Week in Science
Occasionally, a single week makes years of underlying change impossible to ignore. I wrote this essay after an extraordinary week for science and higher education, this reflection steps back from individual headlines to consider the broader relationship between scientific institutions, public trust, and the responsibility of scientists to participate in the world beyond the laboratory.

From the Paper
The Metabolic Lessons of Pregnancy
Pregnancy is one of the greatest metabolic challenges the body ever experiences, making it a remarkable window into human physiology. In this latest installment of my From the Paper series, I revisit one of my published studies asking how skeletal muscle responds to that challenge. Rather than finding metabolic changes unique to gestational diabetes, we found something more surprising: many of the differences we observed were shared across pregnancies complicated by obesity, whether gestational diabetes was present or not.
Looking back at the study years later gave me an opportunity to reflect not only on what we found, but on how research questions evolve—and how unexpected results often become the most interesting ones.

Looking back through these essays, I’m drawn by a common thread: that science is much more than its conclusions. It's a way of asking questions, testing assumptions, changing our minds, and slowly building understanding over time.
That process feels more fragile, and more important, than it did even a few years ago.
Thank you for spending a little time with these essays and for making space for slower conversations about science. I hope you'll find something here that stays with you, sparks a new question, or helps you see a familiar idea in a different way.
Until next time,
Kristen
