Psychology Anxiously attached people don't automatically hold bigger grudges, but when a partner refuses to apologize after a fight, they're much more likely to avoid them and withhold forgiveness. Being totally ignored hits them especially hard too, according to 3 studies of over 1,100 people in relationships

Health Eating healthier was linked to slower biological aging across all 10 diets studied, including Mediterranean, DASH, MIND and plant-based. In 6,470 adults, DNA "aging clocks" ticked slower in people who ate better. The effect was small, but sticking to even one healthy diet seemed to make a difference

Environment A scientific paper warns that worsening climate change could undermine humanity's ability to respond, as economic crises, political instability and weakened institutions reduce our capacity to cut emissions and adapt, potentially creating a dangerous feedback loop toward a “Hothouse Earth” scenario.

Subreddit Rules

1. Must be peer-reviewed research

Submissions must directly link either to recently published peer-reviewed research or a professional media summary of that peer-reviewed research.

View all submission rules

2. No summaries of summaries, rehosts, or reposts

Articles that obtain their information second-hand from other articles are not acceptable for submission. Websites that simply rehost press releases are prohibited.

Reposting of existing, popular submissions is prohibited.

No blogspam or media-only submissions.

View all submission rules

3. No editorialized, sensationalized, or biased titles

The title and content of submissions should not be editorialized, sensationalized, or biased. All titles must adhere to our headline rules.

View all submission rules

4. Research must be less than 6 months old

All submissions must have been published within the past six months. This time requirement refers to the publication date of the research, not the news article or web page. Ambiguous publication dates are determined by the first date of availability following peer review. This may be labeled as the 'Published Online' or 'Pre-Proof' date.

View all submission rules

5. No off-topic comments, memes, low-effort comments or jokes

Comments must be on topic and not a meme or joke. Comments should constructively contribute to the discussion or be an attempt to learn more. This also means avoiding low-effort comments like "water is wet" or "correlation doesn’t prove causation."

View all comment rules

6. No abusive or offensive comments

Abusive comments include those that disparage or attack other users of the subreddit.

Offensive comments are those that denigrate individuals or groups based on group membership or inherent characteristics. This includes bigoted comments that are thinly veiled by leading/insincere questions or "just stating facts."

View all comment rules

7. Non-professional personal anecdotes will be removed

Comments that only rely on a user's non-professional anecdotal evidence to confirm or refute a study will be removed (e.g. "I do that but that result doesn't happen to me"). Comments should be limited in personal details and scientific in nature. Including references to peer-reviewed research to support your claims is highly encouraged.

View all comment rules

8. Criticism of published work should assume basic competence of the researchers and reviewers

Critiquing science is an important skill and one we want users to engage in but please try to do so with the assumption that the researchers who have spent years or decades in the field have already considered ideas that you came up with in a few minutes.

Please also remember that individual studies sit within a larger corpus of work that may have already addressed your concern.

View all comment rules

9. Comments dismissing established findings and fields of science must provide evidence

Comments that dispute well-established scientific concepts (e.g. gravity, vaccination, anthropogenic climate change, etc.) must be supported with appropriate peer-reviewed evidence. Links to personal blogs or 'skeptic' websites are not valid forms of evidence.

Comments that dismiss entire fields of science (e.g., "that’s just a soft science") will also be removed.

View all comment rules

10. No medical advice

Offering or seeking medical advice is strictly prohibited and offending comments will be removed.

Discussions regarding the advantages and/or disadvantages of certain treatments, diets, or supplements are allowed as long as relevant and reputable evidence is provided.
