Today’s r/science threads kept puncturing comforting narratives: bodies are not simple, tech isn’t a singular villain, and nature refuses our tidy labels. The data leaned contrarian—complicating popular fears while exposing overlooked risks and incentives shaping public health and work.
Bodies, biology, and the lucrative business of worry
Health outcomes are less about individual willpower than structural gaps, as a large longitudinal analysis of 10,900 participants showed that childhood ADHD traits predict higher midlife multimorbidity and delayed access to care. When science highlights slow-burn vulnerabilities, it also exposes a system that still treats neurodiversity as an afterthought in screening and support.

That urgency contrasts sharply with the influencer economy, where a study of digital masculinity found testosterone-test hype convinces healthy young men they’re broken, just as evolutionary work reframes physique status-signaling through female choice and male competition shaping penis size and V-shaped bodies. Meanwhile, hard biology reminds us that the most consequential risks can be microscopic, with Fusobacterium nucleatum implicated in breast cancer initiation and spread, and therapeutics are edging toward non-benzodiazepine options via a trial where plant-derived cannabis matched lorazepam for insomnia.

AI anxiety meets uneven gains
The platform’s tech threads converged on a blunt truth: risk perceptions map onto power, exposure, and uncertainty. A survey-driven analysis reported that women are more skeptical of AI than men under economic uncertainty, while production data suggested AI boosts senior developers’ output but leaves early-career coders behind, threatening to widen skill gaps rather than democratize them.
"I see this in my classroom as well… AI misuse skews male, and I suspect the bias may widen the performance gap further." - u/mistephe (1701 points)
And the broader moral panic has shaky footing: a multi-year cohort tracking 25,000 adolescents found little evidence that time on social media or gaming drives psychological distress in early adolescence. If the worry is real but misdirected, policy should pivot from policing screen-time to the offline fundamentals—sleep, family stress, and socioeconomic stability—that the data keep elevating.
Urban canopies and prehistoric towers
“Green is good” is too lazy for public health planning. A massive image-analysis study revealed city residents benefit from tree canopies linked to lower cardiovascular risk, while visible grass correlated with higher risk—an inconvenient finding for cosmetic landscaping that ignores heat, pollution trapping, and chemical inputs.
"The more we learn the more things don’t fit in our neat organizational labels." - u/TazBaz (51 points)
That appetite for complexity extends to deep time: the giant, pre-tree Prototaxites may not be fungal after all, as evidence points toward a potential new lineage that breaks our taxonomic molds. Whether planning a block or rewriting the history of life, r/science’s best threads forced the same discipline—replace vibes with measured, sometimes uncomfortable evidence.
