Science is often remembered through its great papers and landmark discoveries, but much of the thinking that shaped those discoveries travelled in a different way.
Over time, scientific communication evolved into the highly structured system we know today. The development of peer-reviewed journals created an essential framework for validating and sharing research. That structure has brought enormous benefits to science and remains fundamental to the credibility of modern research.
But in the process, something quieter was gradually lost.
Before the modern era of scientific publishing, many ideas moved through letters between researchers. Scientists wrote to one another about observations, questions, unexpected results, and emerging theories. Some of these exchanges were brief notes. Others were thoughtful reflections on problems that were still unfolding.
Many of the scientific ideas we now recognise as milestones were first shared in this way, through correspondence between individuals exploring the same questions from different perspectives.
Researchers such as Isaac Newton, Robert Hooke, Maria Sibylla Merian and later Jane Goodall exchanged observations, arguments, and insights through letters that circulated among small scientific communities. In many cases these exchanges later informed publications or were preserved as part of the scientific record.
This style of communication allowed something that modern scientific publishing sometimes struggles to accommodate the sharing of ideas while they were still developing.
Researchers carry valuable insights that do not fit easily within the format of a formal publication:
- observations that reshape how a problem is approached
- lessons learned during the development of a project
- reflections on emerging areas of science or technology
- practical insights that may help others navigating similar work
Many platforms, including social media, have made communication faster and more visible. At the same time, they can make thoughtful contributions difficult to sustain. High-quality insight often disappears quickly as new material flows through the stream.
The Chronicles are short pieces that allow scientists to step back from the technical detail of a specific paper and discuss the broader insight surrounding their work, the ideas, questions, or experiences that shape how research evolves.
Alongside them sit the ”42s”, a lighter format inspired by the well-known answer to life, the universe, and everything in The Hitchhiker’s Guide to the Galaxy. As brief contributions they can capture a single observation, piece of advice, or perspective that may be useful to others working in related fields.
Scientific progress is rarely the result of a single moment of discovery. More often it emerges through the gradual accumulation of insights shared between people who are exploring similar problems from different angles.
Together, these formats aim to recreate something that has long been part of scientific culture: the exchange of ideas between researchers who are curious about the same questions. Where scientists wrote to each other, shared ideas freely, and allowed curiosity to guide the conversation.
In some ways it represents something new. In other ways, it is simply a return to an older tradition.
