Here are an array of different formats that your work may potentially take. If you have an idea or a story but are feeling stumped about the best way to tell it, have a look through this list. You may even want to include a proposed format with your pitch.
Research paper translation article
This is a timely, short, opinionated reaction to something happening in the news cycle. For example: "The Science Nobel Prizes are sexist, racist, and misleading. Let's rethink them."
This can be in any medium – video, audio, written. Read co-founder Nadja Oertelt's great Q&A with Max Tegmark here.
Read Massive's first-person theme, "It's All Subjective," here.
Another word for this is longform. It compiles a group of scenes to tell a larger story, with a narrative arc, characters, and deeper themes. Getting all these pieces requires interviewing sources, visiting sites, and doing whatever else needs to happen for you to experience or hear everything that ends up in your work. Scientists that do this well include physician-researchers Atul Gawande and Siddhartha Mukherjee (both, in this case, in The New Yorker).
First-person video journal/vlog
The Green brothers have elevated this format to an art. It would be a great personal essay alternative.

Sometimes the best way to articulate something is in gifs. Yes, really.
