Really interesting--p. 7 stood out to me. "Across all three platforms, most teen users say it neither hurts nor helps their mental health...We asked parents how social media overall impacts their teen: About a quarter say they hurt their teen’s mental health, compared with 8% who say they help."

Are smartphones stressful for adolescents? 🤔 Using experience sampling and smartphone trace data, we found that for ~80% adolescents, screen time is neither stress‑inducing nor stress‑buffering. For ~20%, smartphone use is stress‑inducing, but usage patterns matter ⭐ doi.org/10.1177/1461...

TIL the original paper describing CRISPR, by Francisco Mojica, was rejected by 4 journals and took 2 years to be published
CRISPR as a microbial immune system

In 2003, Mojica wrote the first paper suggesting that CRISPR was an innate microbial immune system. The paper was rejected by a series of high-profile journals, including Nature, Proceedings of the National Academy of Sciences, Molecular Microbiology and Nucleic Acids Research, before finally being accepted by Journal of Molecular Evolution in February, 2005.[3][4]

New in JCMC with @bronwynec.bsky.social: People who feel more in control of their social media use tend to use it less and report better well-being. Seeing social media as positive was associated with more use, but not well-being. 👉 doi.org/10.1093/jcmc...
Abstract:

Building on the idea that subjective evaluations of social media use (SMU) may shape well-being effects, this study investigated how two “social media mindsets”—agency (perceived control over SMU) and valence (perceived effects of SMU)—relate to self-reported and logged SMU, and four well-being indicators (depression, anxiety, stress, and life satisfaction) in a South African sample of young adults (N = 1,858; M age = 21.01). Agency mindsets were negatively correlated with SMU and positively with well-being, while valence mindsets were associated with higher SMU but not with well-being. Logged SMU showed weaker associations with mindsets and well-being than self-reported SMU, suggesting differences between perceived and actual behavior. The findings replicate, extend, and in some cases contradict prior research, emphasizing how users’ sense of control is more important for well-being than SMU duration or perceptions of its effects, and that more work is needed to understand whether the “mindsets” concept is fruitful.

Lay summary:

This study investigated how young adults’ feelings about social media—whether they feel in control of their use (agency) or view it positively (valence)—relate to their actual use and mental well-being. The study involved 1,858 participants from South Africa using both self-reported and actual logged social media usage data. The results show that people who feel more in control of their social media use tend to use it less and report better mental well-being. In contrast, those who see social media as more positive spend more time on it, but this mindset did not directly relate to well-being. The data collected from logs of actual usage show weaker relations with well-being compared to people’s estimates and to their mindsets. These findings suggest that a person’s sense of control over social media plays a more important role in their mental health than how much time they spend on it.
