What to post in r/biology

What fits the room, and what gets removed.

Works well

  • Sharing detailed, non-opinionated analyses of complex biological processes.
  • Presenting original, peer reviewed findings from a biological study.
  • Asking thoughtful, informed questions about specific biological mechanisms.
  • Starting a discussion about a recent development in a specific field of biology.

Avoid

  • Asking the community to identify insects, molds, or other specimens, as this violates the survival tip against ID requests.
  • Posting any content that attempts to sell or advertise goods or services, which is strictly forbidden under “No Spamming”.
  • Submitting any posts or comments that contain AI generated content, as this is explicitly banned under “Quality control”.
  • Asking personal health questions or trying to interpret medical results, because this violates “No medical questions”.
  • Posting without having accumulated a reasonable amount of post and/or comment karma on your account, due to the “Low Karma” rule.
  • Submitting pseudoscience or opinion articles, as these are prohibited under “Quality control”.

No pattern yet. r/biology does not have enough top posts from the last 90 days to name its best hours.

What r/biology Is For

This sub is where people talk about all things biology. Content and people from every related field are welcome.

Rules That Matter Before Posting

The rules that decide whether your marketing adjacent post survives are "No Spamming", "Quality control", "No Trolling", "No Hate Speech or Bigotry", and "Low Karma".

What To Post

A good post here is a detailed, accurate, high quality discussion of a biological topic. The community welcomes content from all related fields, so sharing insights or findings from your work is fine as long as they relate to biology. Contribute to the discussion. Don't make the post about promoting yourself.

What To Avoid

Don't submit anything that counts as spam, and that includes crossposting into more than five subs at a time. Don't troll in any form, and baiting other users counts as trolling. Also skip anything low effort or pseudoscience.

A note from Anthony

It's clear to me this community wants deep, accurate discussion over casual interaction. The "Quality control" rule is huge, covering everything from low effort posts to AI content, so prepare before you post. I didn't see any top posts, which tells me the quality bar is very high. Focus on giving genuine value.
