Full Story

To help control the spread of COVID-19, the Centers for Disease Control and Prevention has recommended getting a COVID-19 test for people who show symptoms of the disease, have come into contact with someone known to have the disease, or are in vulnerable groups. 

The most common form of testing for the novel coronavirus involves the use of a nasopharyngeal, or nasal, swab. The swab reaches deep into the back of a person’s nose and mouth to collect cells and fluids from the upper respiratory system, which can then be checked with diagnostic tests for the presence of the novel coronavirus known as SARS-CoV-2.

The testing procedure involves inserting a 6-inch-long swab into the cavity between the nose and mouth for 15 seconds and rotating it several times. The swabbing is repeated on the other side. The swab is then inserted into a container and sent to a lab for testing.

Dr. Shawn Nasseri, an ear, nose and throat surgeon based in Beverly Hills who has conducted many COVID-19 swab tests, told us in an email that the nasal swab “follows the floor of the nose and goes to where the nose meets the throat, or naso-pharynx.”

Asked if the swab test is safe, Nasseri said, “Absolutely. The biggest risk is discomfort. The rare person — 1 in thousands — passes out from being super sensitive or gets a mild nosebleed. It’s estimated that close to 40 million or more swabs have been performed safely in the U.S. alone.”

But in recent weeks, viral posts on Facebook falsely claim that the nasal swab test can cause serious health issues. One post says, “The stick deep into the nose causes damage to the hamato-encephalic barrier and damages endocrine glands. This test creates an entrance to the brain for every infection.”

The hamato-encephalic barrier, also known as the “blood-brain barrier,” protects the brain from toxins that could be present in the blood.

Dr. Yvonne Maldonado, a professor of epidemiology at the Stanford University School of Medicine, told us in an email that the Facebook claim “is not true.”

The website claims that "the more you sip, the smarter you (and the bottle) get," but in reality the more you sip, the drunker you get and the less information you'll retain.

Nasseri said that “it is incredibly implausible, if not impossible, to cross the skull base and blood-brain barrier with a swab unless someone uses a rigid metal instrument and is pointing the metal object 90 degrees in the wrong direction.”

Dr. Morgan Katz, an infectious disease expert at Johns Hopkins University, told the Associated Press that the Facebook posts misunderstand what’s happening when the swab test is performed.

根据中国海关总署(General Administration of Customs)的数据,在经历了此前一个月的同比下跌1.4%之后,11月份中国的进口同比增长6.7%,至1522亿美元,远高于同比收缩1.9%的预测中值。
那么多的人视而不见,不承认事实。真相是泡沫无处不在,随时准备爆掉。证据越来越多,结论只有显而易见的一个:泡沫破灭的风险最高可达98%。2014年这次崩盘几乎是铁定要发生的,躲过这枚子弹的概率只有区区2%。
首先,Bitstamp遭遇黑客袭击,以及2011年黑客袭击比特币交易平台Mt. Gox(此次黑客袭击要严重得多,其损失当时约合4亿美元),往往被误解为比特币本身存在安全问题。但事实上,这只能表明上述比特币交易平台存在缺陷,而非比特币技术本身存在问题。而最令人激动的,正是比特币背后的底层技术。正如《财富》杂志2015年1月刊《打造未来》系列报道中所写,大部分极为看好比特币、为其大声疾呼的狂热粉丝(包括马克o安德森这样的大牌企业家,也包括花大把时间更新比特币REDDIT页面的开发者和比特币“矿工”),更感兴趣的是能建立在比特币“区块”(该货币基本骨架)上的应用,而非比特币货币体系。两个实体间可通过“区块”安全交换任何形式的价值。
