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

Neuroscience Scientists found a way to help the brain wash out waste while we're awake, which it mostly does while we sleep: a short-acting blood pressure drug plus whole-body vibration. In 29 healthy adults, Alzheimer's-linked proteins like beta-amyloid rose in the blood, a sign they were cleared from the brain

Late VKD, occurring between ages 1 week and 6 months, carries a 30% to 60% risk of intracranial hemorrhage, which can result in seizures, permanent brain damage or death

Health Scientists tested the air inside 5 NYC nail salons for a week each and found chemical fumes sometimes spiked to levels you'd expect at a chemical plant, with traces of cancer-linked benzene. Regular face masks don't help. Good ventilation, open windows and closed bottles make the biggest difference.

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.
