    人工智能合成生物学具有巨大的潜力,但也显著增加了生物多样性,并带来了一系列新的双重用途问题。考虑到通过结合新兴技术而设想的巨大创新,情况很复杂,人工智能合成生物学有可能将生物工程扩展到工业生物制造。然而,文献综述表明,诸如保持合理的创新范围等目标,或者更雄心勃勃地培育巨大的生物经济不一定与生物安全形成对比,但需要手牵手。本文介绍了有关问题的文献综述,并描述了跨命令与控制选项的新兴政策和实践框架,管理,自下而上,和自由放任的治理。如何实现预警系统,使实验室能够预防和缓解未来人工智能生物危害,从故意滥用,或者来自公共领域,会不断需要进化,和适应性,交互式方法应该出现。尽管Biorisk受既定治理制度的约束,科学家们普遍遵守生物安全协议,甚至是实验性的,但是科学家的合法使用可能会导致意想不到的发展。由生成AI实现的聊天机器人的最新进展重新引发了人们的担忧,即先进的生物洞察力更容易落入恶性个人或组织手中。鉴于这些问题,社会需要重新思考人工智能合成生物学应该如何管理。想象当前挑战的建议方法是打痣治理,尽管新兴的解决方案可能也没有太大不同。
    AI-enabled synthetic biology has tremendous potential but also significantly increases biorisks and brings about a new set of dual use concerns. The picture is complicated given the vast innovations envisioned to emerge by combining emerging technologies, as AI-enabled synthetic biology potentially scales up bioengineering into industrial biomanufacturing. However, the literature review indicates that goals such as maintaining a reasonable scope for innovation, or more ambitiously to foster a huge bioeconomy do not necessarily contrast with biosafety, but need to go hand in hand. This paper presents a literature review of the issues and describes emerging frameworks for policy and practice that transverse the options of command-and-control, stewardship, bottom-up, and laissez-faire governance. How to achieve early warning systems that enable prevention and mitigation of future AI-enabled biohazards from the lab, from deliberate misuse, or from the public realm, will constantly need to evolve, and adaptive, interactive approaches should emerge. Although biorisk is subject to an established governance regime, and scientists generally adhere to biosafety protocols, even experimental, but legitimate use by scientists could lead to unexpected developments. Recent advances in chatbots enabled by generative AI have revived fears that advanced biological insight can more easily get into the hands of malignant individuals or organizations. Given these sets of issues, society needs to rethink how AI-enabled synthetic biology should be governed. The suggested way to visualize the challenge at hand is whack-a-mole governance, although the emerging solutions are perhaps not so different either.

    早期育儿经验对母婴依恋关系发展的作用已得到广泛研究。然而,没有关于早期儿童保育的前瞻性研究探讨这些经历如何反映在青春期及以后的依恋表征内容中.这项研究的目的是估计儿童护理质量之间相对精确的关联,儿童保育数量,以及生命最初54个月的护理类型和18岁左右青少年依恋陈述的内容(N=857;51%女性;78%白人,非西班牙裔;M收入需求比=4.13),利用NICHD早期儿童保育和青年发展纵向研究(SECCYD)的数据。我们发现观察到的早期儿童护理质量(但不是护理的数量或类型)与18岁时通过成人依恋访谈(但不是依恋脚本评估)测量的安全依恋状态之间存在小的正相关,这对于人口统计学协变量和童年时期母亲和父亲敏感性的观察是稳健的。我们观察到儿童护理变量之间没有显著的相互作用。从婴儿期到青春期中期的母亲敏感性或幼儿时期的母亲对儿童气质的报告也没有调节早期育儿经历与青少年依恋指标之间的关联。
    The role of early child care experiences on the development of the mother-child attachment relationship has been studied extensively. However, no prospective studies of early child care have addressed how these experiences might be reflected in the content of attachment representations during adolescence and beyond. The goal of this study was to estimate relatively precise associations between child care quality, child care quantity, and type of care in the first 54 months of life and the content of adolescents\' attachment representations around age 18 years (N = 857; 51% female; 78% White, non-Hispanic; M income-to-needs ratio = 4.13), leveraging data from the longitudinal NICHD Study of Early Child Care and Youth Development (SECCYD). We identified a small positive association between the observed quality of early child care (but not quantity or type of care) and secure attachment states of mind as measured by the Adult Attachment Interview (but not the Attachment Script Assessment) at age 18 years that was robust to demographic covariates and observations of maternal and paternal sensitivity during childhood. We observed no significant interactions among child care variables. Associations between early child care experiences and indicators of adolescent attachment were likewise not moderated by maternal sensitivity from infancy to mid-adolescence or by maternal reports of child temperament in early childhood.

    A large body of evidence has shown that stress throughout life is associated with health trajectories, but the combination of adverse experiences at different stages of the life course is not yet well understood. This study examines the interactions between childhood adversity, adulthood adversity, and adult physical and mental health. Using data from The Childhood Retrospective Circumstances Study (CRCS) supplement to the Panel Study of Income Dynamics (PSID), we created indices of early life adversity (EAI) and adult adversity (AAI). We used logistic regression to examine the effects of EAI and AAI, adjusting for age, sex, race/ethnicity, health behaviors, and childhood health as covariates in all models. We repeated this analysis for the outcomes of fair/poor health, two or more chronic conditions, and psychological distress in adulthood. For all the three outcomes, our findings suggest increasing salience of adult adversity among those who experienced higher levels of early adversity. Individuals with high EAI and high AAI exhibited the highest odds of fair/poor health (OR = 5.71), chronic conditions (OR = 3.06), and psychological distress (OR = 13.08) compared to those with low EAI and low AAI. These findings are consistent with the accumulation of risk or dual risk model of stress and health. Adversity in childhood amplifies the health risks associated with stress in adulthood for multiple health outcomes.
