Fauci Says He Didn’t Play Down China Lab-Leak Theory of Covid-19 Origins


“This is not a major threat that the people of the United States should be worried about.” Dr. Anthony Fauci, January 21, 2020.
“I think you are going to see a dampening down of U.S. cases.” Dr. Anthony Fauci, February 3, 2020.
“In order to get a vaccine that’s practically deployable for people to use, it’s going to be at least a year to a year and a half at best.” Dr. Anthony Fauci, February 26, 2020
“There’s no reason to be walking around with a mask.” Dr. Anthony Fauci, March 8, 2020

Dr. Fauci was informed as early as February 2020 that Covid-19 exhibited unusual viral characteristics that suggested it could have potentially been engineered in a lab, according to emails recently obtained by the Washington Post and BuzzFeed.

Some Republican lawmakers have used the emails to accuse Dr. Fauci of having played down the lab-leak theory.

“Most of the people thought what all of us were thinking at the time—that it was very likely a natural evolution. But we never ruled out the possibility. We were very open about it. It wasn’t like we were trying to hide anything,” he said.


Dr. Fauci said misinformation that has been circulated about the virus, particularly around it being a hoax, has ultimately cost lives, because some people didn’t wear masks or social-distance as a result.

这项研究是由加利福尼亚州劳伦斯利弗莫尔国家实验室(Lawrence Livermore National Laboratory) 2020年5月筹备的,美国国务院在特朗普政府任期的最后几个月调查疫情起源时借鉴了这项研究。









美国国务院的上述结论经过了美国情报机构的审查,今年1月15日通过一份资料概览(fact sheet)公布,这份资料概览列出了认为新冠疫情可能源于一场实验室事故的一系列间接理由。其中包括这样的论断:“美国政府有理由认为,武汉病毒研究所内部的数名研究人员在2019年秋天生病”,症状与2019冠状病毒病或季节性流感相符。

Researchers rewire the genetics of E. coli, make it virus-proof


Many of the fundamental features of life don’t necessarily have to be the way they are. Chance plays a major role in evolution, and there are always alternate paths that were never explored, simply because whatever evolved previously happened to be good enough. One instance of this idea is the genetic code, which converts the information carried by our DNA into the specific sequence of amino acids that form proteins. There are scores of potential amino acids, many of which can form spontaneously, but most life uses a genetic code that relies on just 20 of them.

Over the past couple of decades, scientists have shown that it doesn’t have to be that way. If you supply bacteria with the right enzyme and an alternative amino acid, they can use it. But bacteria won’t use the enzyme and amino acid very efficiently, as all the existing genetic code slots are already in use.

In a new work, researchers have managed to edit bacteria’s genetic code to free up a few new slots. They then filled those slots with unnatural amino acids, allowing the bacteria to produce proteins that would never be found in nature. One side effect of the reprogramming? No viruses could replicate in the modified bacteria.

Early adopters of Chinese vaccines see case surges; China plows ahead anyway


The dramatic ramp up comes at an awkward time, however. Early adopters of China’s vaccines have seen dramatic surges in COVID-19 cases—despite high vaccination rates—and are now backing away from the country’s offerings.

In Bahrain, for instance, officials are now offering high-risk people who have already received two doses of China’s Sinopharm vaccine a third vaccine dose—but one made by Pfizer-BioNTech. The apparent vote of no confidence by officials is striking: Bahrain was one of the first countries to back and rollout Sinopharm’s vaccine, and it has had a highly successful vaccination campaign. Nearly 58 percent of the Persian Gulf country has received at least one dose of a vaccine, and most of the vaccines given in Bahrain are from Sinopharm. But the country is now seeing its worst wave of COVID-19 yet and the government has recently issued a two-week lockdown to try to get transmission under control.

The Seychelles went through a similar struggle. The archipelago saw a dramatic spike in cases in mid-May, despite having around 70 percent of its population vaccinated with at least one dose. Like Bahrain, the Seychelles had largely relied on the Sinopharm vaccine.

Dubai, which has also relied on Sinopharm’s vaccine, is now quietly offering residents who have been fully vaccinated with the Sinopharm vaccine the opportunity to get re-vaccinated with the Pfizer-BioNTech vaccine, according to The Wall Street Journal.

  此次争论来自于一篇题为《抗体靶向的新冠病毒刺突蛋白上的感染增强位点》(An infectivity-enhancing site on the SARS-CoV-2 spike protein targeted by antibodies),5月24日发表在《细胞》杂志上。作者为大阪大学微生物疾病研究所免疫化学系Hisashi Arase等人。


  前述研究分离了74株新冠康复者的单克隆抗体,在体外细胞实验中进行测定后,发现其中6株抗体可增强新冠病毒与人体细胞的结合、4株抗体可加剧新冠病毒对细胞的感染。研究团队由此得出结论,在感染新冠病毒的过程中,具有抗病毒效力的“中和抗体”(neutralizing antibodies)和可以加剧病情的“增强抗体”(enhancing antibodies)都会产生。

美国以游说遣返郭文贵为由要求博彩业大亨Steve Wynn登记为外国代理人


据知情人士透露,美国司法部要求博彩业大亨Steve Wynn注册为游说者,这与他在2017年争取中国当局长期寻求的外交帮助有关,司法部还准备诉诸法庭迫使他遵守规定。

知情人士说,检方已收集了有关Wynn近几个月工作的证据,以便为如果他不提交任何此类登记,可能提起的诉讼做准备。如果提起诉讼,此案将成为一场罕见的根据《外国代理人登记法》(Foreign Agents Registration Act)进行登记的民事法庭之争。该法律没有规定民事处罚,但它赋予了司法部寻求法院命令强制某人遵守的权力。

去年7月,时任美国司法部长的巴尔(William Barr)警告说,按照中国有关部门的要求推行政策的公司高管可能会被要求依法登记,但司法部尚未提起任何此类诉讼。
