$Facebook(FB)$有利空的涨最多，没利空的高开低走，美股这操纵得太畸形了

$标普500ETF(SPY)$做空真是会亏到裤衩都没

2020-06-04

$标普500ETF(SPY)$美联储无限量印钞托底，股市只跟流动性有关，跟基本面已经没什么关系了，只要美联储不收紧政策，股市就没什么理由跌。

$美国原油ETF(USO)$这是什么情况，比两倍杠杆的还高两倍多涨幅，这不是持仓多月份原油合约的组合吗？怎么走势也奇葩了

2020-05-06

$标普500ETF(SPY)$所有人都说空的时候就是庄家拉升的时候

2020-01-27

病毒来源是野生动物不代表着是自然起源的病毒，正常的自然起源病毒不可能在大城市里起源而乡村里没有的

蛇、水貂、蝙蝠，新型冠状病毒究竟来自哪种野生动物？

of Medical Virology）的一篇论文指出，与刺猬、穿山甲等其他动物相比，2019-nCoV的密码子使用偏好与蛇类似，因此蛇最有可能是携带新型冠状病毒的动物。关于蛇是此次新型冠状病毒中间宿主的说法一经发布便遭到质疑。1月23日，《自然》杂志发布的一篇评论指出，“他们没有证据表明蛇可以被这种新的冠状病毒感染并作为宿主，除了哺乳动物和鸟类以外，不存在一致的证据证明其他宿主中存在beta冠状病毒。”科研自媒体《知识分子》发表文章质疑，此前流行的SARS和MERS病毒的自然宿主均是蝙蝠，通过果子狸和骆驼传染给人，也就是说，病毒的传递是在哺乳动物之间进行的。但蛇不是哺乳动物，而是爬行类。质疑文章认为，“好比一个人从武汉出发去北京，如果中间必须转一次车，他最合理的选择是在武汉到北京之间的一站，比如郑州。但如果有人建议他到贵阳去转车，就会让人感到意外了。”“很多病毒是存在跨种族直接传播的可能性，病毒通过蛇传染给人也是一样。不过，生物信息学研究只能推测，需要动物实验进行验证。”罗光湘举例称，1997年的禽流感大流行已经证明病毒可以跨族属传播，高致病性的H51N1禽流感病毒可以直接传染给人，不需要通过哺乳动物作为中间宿主。值得注意的是，1月26日，中国疾控中心病毒病所首次从华南海鲜市场的585份环境样本中，检测到33份样品含有新型冠状病毒核酸，并成功在阳性环境标本中分离病毒，提示该病毒来源于华南海鲜市场销售的野生动物，但研究并未锁定是哪一种具体的动物。寻找中间宿主有利于切断病毒传播链，但病原追溯过程可能会长达数十年。2003年SARS时期，专家通过前期的流行病学调查，很快将目标瞄准广东野生动物市场，并从市场上售卖的果子狸体内分离和检测到了和SARS病毒完全一样的病毒。在政府下令全面捕杀果子狸，并关闭野生动物市场后，广东再没有出现SARS新增病例。然而，果子狸只是SARS病毒传播的“中间站”。石正丽团队调查了全国各地的养殖果子狸和野生果子狸，却发现它们并没有被SARS病毒感染的证据。经过13年的追踪，研究团队在云南山洞中确定了SARS病毒的蝙蝠起源。不过，此次武汉新型冠状病毒的溯源，可能很难像SARS期间锁定果子狸那样高度确认。宾夕法尼亚大学医学院微生物学系副研究员李懿泽此前对媒体表示，如果现场已被破坏，没有及时采集当时所售的野生动物样品，那就只能通过大规模筛查野生动物的方式找到中间宿主，难度极大。除了病原追溯，新型冠状病毒感染人体的确切途径也在研究中。北京大学免疫学教授王月丹撰文指出，利用获得的新型冠状病毒毒种，可以建立动物传播与感染模型。一方面可以对新型冠状病毒进行追踪溯源，找到其可能来源的野生动物；另一方面，也可以利用毒种进行动物的染毒研究，阐明其确切的感染途径，找到可以完全阻断新型冠状病毒传播的方式，指导临床的预防与隔离工作。“目前防控和治疗的重点应该集中放在早发现，早诊断，早治疗，防止病毒继续扩散。”罗光湘认为，今后至少要让任何野生动物不能够在市场上交易，不能让这种携带病原的野生动物来到大城市，同时教育公众不要吃野生动物，“这对以后的疫情控制都很重要”。（实习记者刘世龙对本文亦有贡献。）","news_type":1},"isVote":1,"tweetType":1,"viewCount":1857,"authorTweetTopStatus":1,"verified":2,"comments":[{"author":{"id":"3527667803686145","authorId":"3527667803686145","name":"社区成长助手","avatar":"https://static.tigerbbs.com/2b7c7106b5c0c8b0037faa67439d898f","crmLevel":1,"crmLevelSwitch":0},"content":"终于等到了您的初发帖[比心][比心]希望您能在老虎社区玩得愉快、赚得开心！如果您想创作优质文章，请查看老虎社区创作指引","text":"终于等到了您的初发帖[比心][比心]希望您能在老虎社区玩得愉快、赚得开心！如果您想创作优质文章，请查看老虎社区创作指引","html":"终于等到了您的初发帖[比心][比心]希望您能在老虎社区玩得愉快、赚得开心！如果您想创作优质文章，请查看老虎社区创作指引"}],"imageCount":0,"langContent":"CN","totalScore":0}],"hots":[{"id":953048718,"gmtCreate":1590069670534,"gmtModify":1704191724071,"author":{"id":"311272067508640","authorId":"311272067508640","name":"周BB","avatar":"https://static.laohu8.com/default-avatar.jpg","crmLevel":1,"crmLevelSwitch":0,"followedFlag":false},"themes":[],"htmlText":"<a
