一 | While scientists and science fiction authors alike have long dreamed of sending crewed missions to Mars, a new study suggests these plans may hit a snag – a big one.,The authors of a yet to be peer-reviewed study argue that the participants of such a mission to Mars would end up being exposed to radiation – namely, to “energetic charged particles from Galactic and Solar origin” – both while in transit and while on the planet itself, with the “thin spacecraft shield” and “rarefied Martian atmosphere” offering little in the way of protection.,The research team attempted to gauge the impact of a simulated 1,000-day mission to Mars on various organs of the human body, and concluded that astronauts may be exposed to radiation doses above one Sievert, which is over the safe limit set by most space agencies, New Scientist points out.,“We suggest mitigation strategies such as improved ways of shielding and dietary supplements, and make recommendations for the safety of astronauts in future crewed missions to Mars,” the team wrote in the abstract of their work available on the arXiv preprint server.,Ideas about how astronauts may be protected from radiation during a mission to Mars have already been proposed, such as the concept of a radiation shield comprised of a fungus found growing at the Chernobyl Nuclear Power Plant.,Last year, one architecture studio even unveiled a project for a self-sufficient and sustainable city that would be built on the red planet itself.。
二 | 华泰证券研报称，市场对港股中期走势受基本面影响的程度分歧不大，关键变量在全球流动性环境。华泰证券认为，美元因公信力挑战转弱、人民币升值强化，有助于港股AH溢价再度收窄及香港金融资产重估。但对总体市场而言，本轮弱美元所处背景并非去年全球金融条件宽松和risk-on环境，流动性环境偏紧方向并未改变。海外10年美债利率大概率高位震荡，日元再度外汇干预或加息都有可能发生，8月央行年会是关注重点。香港在海外提短端控长端思路及港元汇率偏弱的情况下，HIBOR有可能进一步上行。因流动性难有增量支持，财报季尚未被充分定价，盈利兑现度更为重要。配置上维持均衡：低波红利（如银行）为底仓；关注中报或确认经营底部的乳品、部分零售；AI链（如晶圆代工）定位进攻品种、小仓位参与超跌反弹；CXO和创新药龙头兑现度高但短期性价比下降，行情斜率或放缓。
