主题：【转发】以色列暗网情报:美国科学家研究并泄漏新冠病毒 -- 菜根谭

在新冠致死率逐渐降低，全球开始寻找方法如何与病毒共存的时候，美国波士顿大学的科学家因在实验室中制造出更致命的新冠新毒株而被谴责在“玩火”！

波士顿大学的研究人员表示，他们开发出了一种新的新冠毒株，将目前占主导地位的奥密克戎（Omicron）变种和2019年底在中国首次发现的原始毒株进行结合，经过一系列类似的实验后，该毒株的传染性是奥密克戎的五倍，致死率达到了80%！

在这项未经同行评审的新研究中，来自波士顿和佛罗里达州的一组研究人员提取了奥密克戎变种的刺突蛋白，附加到疫情刚开始时的原始新冠毒株上，将其命名为奥密克戎 S（Omicron S）。

研究人员在实验鼠身上对这种杂交毒株进行了实验，并与奥密克戎毒株进行了对比。

他们在论文中写道：“在K18-hACE2小鼠中，虽然奥密克戎会导致轻度、非致命的感染，但奥密克戎 S 的病毒会导致严重的疾病，死亡率为 80%。”

在只接触奥密克戎毒株的组里，这些老鼠都活了下来，并且只出现了“轻微”症状。

Abstract

To prevent future pandemics, it is important that we understand whether SARS-CoV-2 spilled over directly from animals to people, or indirectly in a laboratory accident. The genome of SARS-COV-2 contains a peculiar pattern of unique restriction endonuclease recognition sites allowing efficient dis- and re-assembly of the viral genome characteristic of synthetic viruses. Here, we report the likelihood of observing such a pattern in coronaviruses with no history of bioengineering. We find that SARS-CoV-2 is an anomaly, more likely a product of synthetic genome assembly than natural evolution. The restriction map of SARS-CoV-2 is consistent with many previously reported synthetic coronavirus genomes, meets all the criteria required for an efficient reverse genetic system, differs from closest relatives by a significantly higher rate of synonymous mutations in these synthetic-looking recognitions sites, and has a synthetic fingerprint unlikely to have evolved from its close relatives. We report a high likelihood that SARS-CoV-2 may have originated as an infectious clone assembled in vitro.
