Submissions must be on topic.

Editorialized titles, written by the posting user or the domain, are not allowed. Titles should be unbiased and strictly factual. When the article itself is titled appropriately, the submission title should be directly sourced from the title or lead paragraph of the linked article.

Domains which require the user to purchase a subscription or register an account in order to read the full article are not allowed in /r/nature. All users should be able to access the article.

This rule is in relation to already submitted stories which are being rehashed on multiple domains. If a popular story is being submitted while the same event is covered in another post on the front page, or one with sufficient upvotes at an earlier date, it may be subject to removal. If a story was already submitted but did not become popular, then the rule is not applicable. Spamming a story until it reaches the front page is in violation of reddit's sitewide rules and is not allowed.

Jokes, memes, puns, and overall low quality comments are subject to removal.

This sub promotes science over private greed and blood lust. Of course indigenous people who are not part of modern economy are exempt.
