6New study reveals that sleep prevents unwanted memories from intruding: « Sleep problems play an important role in the onset and maintenance of many mental health problems, but the reason for this link is elusive. »
- A new study from the University of East Anglia reveals that sleep helps prevent unwanted memories from intruding into consciousness by engaging brain regions that control memory suppression. Research shows that well-rested individuals have better ability to control unwanted thoughts, with REM sleep playing a crucial role in restoring prefrontal control mechanisms.

7Women’s bodies are moralized more than men’s, study finds | This tendency to moralize women’s bodies could help explain why society often places stricter controls and judgments on women’s bodies compared to men’s.
- Research shows that society tends to view women's bodies through a moral lens more than men's bodies, leading to stricter controls and judgments on women's bodily autonomy. This moral scrutiny extends to various behaviors like public toplessness and is influenced by sexist beliefs.
Study methodology criticism
Multiple users critique the small sample size (470), biased participant selection, and questionable methodology. Scientists express concern about weak peer review standards in social sciences.Reproductive biology impact

Users debate whether studying obvious social phenomena has value, with some arguing for importance of scientific documentation while others dismiss it as unnecessary.
8Men who reported higher levels of socially-prescribed perfectionism had partners who reported higher levels of sexual distress. This suggests that when men feel pressured to be perfect by others, it may contribute to negative sexual experiences for their partners.
- A study in The Journal of Sex Research found that individuals with high personal standards experience stronger desire for their partners, while those feeling pressured by others' expectations show lower sexual function and higher distress, with potential spillover effects on their partners.

9Reintroducing wolves to Scottish Highlands could help address climate emergency | Control of red deer by wolves could lead to an expansion of native woodland that would take up - or sequester - one million tonnes of CO2 each year - equivalent to approximately 5% of the carbon removal
- A University of Leeds study suggests reintroducing wolves to the Scottish Highlands could help expand native woodlands and store one million tonnes of CO2 annually. The research estimates 167 wolves could control red deer populations, enabling natural tree regeneration and contributing to UK's 2050 net-zero goals, with each wolf potentially providing £154,000 worth of carbon storage benefits.
Yellowstone comparison
While wolves helped restore Yellowstone's ecosystem, Scotland's situation differs due to smaller wilderness areas, more human settlements, and infrastructure built assuming wolves' extinction.Sheep predation concerns
Farmers oppose wolf reintroduction fearing sheep losses. Solutions like compensation schemes and guard dogs are proposed, with Dutch experience showing significant livestock attacks.Hunting alternative
Suggestions to manage deer through hunting face resistance from locals opposed to American hunters, while others note hunting differs from natural predation in target selection.
10Water chlorination levels in US and EU likely increase cancer risk, study finds - Bladder cancer risk increased 33% and colorectal cancer by 15% in using chlorine to disinfect water.
- A systematic review and meta-analysis examined links between drinking water trihalomethanes (THMs) and cancer risk. Analysis of multiple studies found increased risks for bladder and colorectal cancers associated with THM exposure, with significant risks for bladder cancer above 41μg/L. The findings suggest current US and EU regulatory limits may not adequately protect against cancer risk in the general population.
Title accuracy correction
Multiple experts point out the study examines trihalomethane byproducts of chlorination, not chlorine itself, making the post title misleading. THMs are already monitored and regulated.Risk vs benefit analysis
Discussion weighs slight increased cancer risk (1% to 1.33%) against major benefits of preventing waterborne diseases. Consensus that chlorination's benefits outweigh risks.Water treatment methods
Experts discuss alternatives like UV treatment and home filtration, noting chlorine remains most practical for maintaining water safety through distribution systems due to its residual disinfecting properties.
