Sarah Crespi: 我对气候工程持谨慎态度,但承认未来可能需要采取此类措施。我们需要了解不同方法的有效性和潜在副作用。 我关注的是公众的抵触情绪,以及在如此大规模的干预措施面前,我们如何获得公众的认可和支持。 我们需要更多地了解气候工程的潜在影响,以及如何与公众进行有效的沟通和协商,以确保在采取任何行动之前,充分考虑所有利益相关者的观点和担忧。 Rebecca White: 气候工程包含两个不同的领域:碳移除和太阳能地球工程。碳移除更易被公众接受,而太阳能地球工程则存在争议,因为它不解决气候变化的根本问题。 在加利福尼亚州的太阳能地球工程测试中,由于缺乏与当地社区的沟通,导致项目遭遇了负面反应。 成功的公众参与需要持续的双向沟通,并重视公众的担忧。在康沃尔郡和哈利法克斯的海洋碳移除测试中,Planetary公司获得了不同的公众反响,这突显了沟通和社区参与的重要性。 对于大型碳移除设施或新技术的测试,需要与受影响的社区进行沟通。太阳能地球工程的影响范围更广,需要大规模的公众参与和讨论。 Marlena Fejzo: 我通过自身经历,研究了妊娠剧吐的遗传因素,并发现了两个相关的基因:GDF-15和IGF-BP7。 GDF-15基因的变异会导致该激素水平降低,从而增加妊娠剧吐的风险。胎儿遗传的GDF-15基因变异会影响母亲妊娠剧吐的严重程度。 我们可以通过增加或降低GDF-15激素水平来进行干预。例如,二甲双胍可以增加GDF-15的水平,而NGM 120则可以阻断GDF-15信号通路。这些方法为妊娠剧吐的治疗提供了新的希望。

Geoengineering experiments face an uphill battle, and a way to combat the pregnancy complication hyperemesis gravidarum

First up on the podcast, climate engineers face tough conversations with the public when proposing plans to test new technologies. Freelance science journalist Rebekah White) joins host Sarah Crespi to discuss the questions people have about these experiments and how researchers can get collaboration and buy-in) for testing ideas such as changing the atmosphere to reflect more sunlight or altering the ocean to suck up more carbon dioxide.

 

Next on the show, hyperemesis gravidarum—severe nausea and vomiting during pregnancy—is common in many pregnant people and can have lasting maternal and infant health effects. This week, Marlena Fejzo wrote about her path from suffering hyperemesis gravidarum to finding linked genes and treatments for this debilitating complication). For her essay, Fejzo was named the first winner of the BioInnovation Institute & Science Translational Medicine Prize for Innovations in Women’s Health). Fejzo) is a scientist at the Center for Genetic Epidemiology in the department of population and public health sciences at the University of Southern California’s Keck School of Medicine.
