●国家卫健委：发热门诊就诊患者需进行核酸检测

National Health Commission: Nucleic acid test is required for patients in fever clinic

6月11日，国家卫健委官网发布通知：对于所有到发热门诊就诊的患者，必须扫“健康码”，并进行核酸检测。对于待排除和疑似病例要第一时间进行隔离医学观察，提供基本医疗服务。（医政医管局）

On June 11, the National Health Commission issued a notice on its official website: all patients who go to the fever clinic must be scanned for the "health code" and tested for nucleic acid. Quarantine medical observation and basic medical services should be provided as soon as possible for excluded and suspected cases. (nhc.gov.cn)

●张文宏：全球第二波疫情在路上，力度或超第一波

Zhang Wenhong: The second wave of the pandemic is on its way, and it may be stronger than the first wave

张文宏在接受采访时指出，国际上第二波疫情已呼之欲出，很多国家的高峰都不知道什么时候到来，例如巴西、印度、俄罗斯。至于疫情最严重的美国，复工复产以后，很多州的疫情又开始出现反弹迹象。面对输入性风险和压力，中国的目标是不受全球第二波疫情影响。经过此次抗疫，我国的公共卫生体系比原来更加强大，可以应对输入性风险。（科普中国）

In an interview, Zhang Wenhong pointed out that the second wave of the epidemic of COVID-19 is imminent in the world, and many countries do not know when the peak will come, such as Brazil, India and Russia. As for the US, the worst-hit country, many states are showing signs of a rebound after returning to work. Faced with imported risks and pressures, China aims to be immune to the second wave of the global epidemic. After the outbreak, China's public health system is stronger than before and can cope with imported risks. (kepuchina.cn)

●新冠病毒靠会导致血栓并致人死亡

Novel Coronavirus can cause a blood clot and death

《柳叶刀-血液病学》（The Lancet Haematology）近日发表社论，文章指出，随着病情的发展，COVID-19重症患者可发生弥散性血管内凝血。早期预防血栓可能是控制凝血病的关键。由于抗病毒治疗在疾病早期通常是有效的，针对炎症和凝血的治疗策略可能对COVID-19重症患者更有意义。（柳叶刀）

An editorial in The Lancet Haematology recently noted that patients with severe COVID-19 can develop disseminated intravascular coagulation as the disease progresses. Early prevention of thrombus may be the key to control clotting. Since antiviral therapy is often effective in the early stages of the disease, treatment strategies targeting inflammation and clotting may be more meaningful for patients with severe COVID-19.

●英国科学家建议用铜抗疫

British scientists have suggested using copper to fight Novel Coronavirus

据《每日邮报》报道，英国科学家建议使用铜对抗新冠病毒感染的蔓延。南安普敦大学高级微生物学家威廉•基维尔称，在门把手、公共交通中的扶手和超市的手推车上都需要覆盖一层铜：这能阻止新冠病毒的传播。先前的研究表明，病毒可以在钢和塑料上“停留”三天，同时具备危险性。不过，新冠病毒在铜皮外层只需几个小时就会死亡，因为铜离子会攻击其保护壳，然后会进入病毒细胞并破坏其DNA，最终导致病毒死亡。（俄罗斯卫星通讯社）

According to the Daily Mail, British scientists have proposed using copper to combat the spread of novel Coronavirus. According to William Kivell, senior microbiologist at the University of Southampton, copper should be covered on doorknobs, handrails on public transport and supermarket trolleys: this will stop the novel Coronavirus from spreading. Previous studies have shown that the virus can stay on steel and plastic for up to three days and can be dangerous. But the novel Coronavirus will die within a few hours on the copper shell, because the copper ions will attack the protective shell of the virus, then enter the viral cell and destroy its DNA, ultimately killing it.

●Cell：熬夜致死，问题不在大脑或心脏，而是肠道

Cell: Long-term late nights were linked to premature death because of the build-up of oxides in the gut

美国哈佛大学医学院 Dragana Rogulja 教授带领的研究团队《细胞》（Cell）杂志上发表研究成果，研究人员发现长期熬夜之所以会引发过早死亡，是源于氧化物在肠道内的堆积，大量破坏 DNA 以及细胞内的其他成分。而且研究人员通过实验进一步证实，通过主动清除动物肠道内的氧化物，即使长期熬夜，其寿命也和保持正常作息的动物没有差异。（学术头条）

Writing in the journal Cell, the researchers, led by Professor Dragana Rogulja of Harvard Medical, found that long-term late nights were linked to premature death because of the build-up of oxides in the gut, which destroy DNA and other components of the cells. And the researchers further confirmed that by actively removing the oxides from the animals' guts, even those that stayed up late had the same lifespan as those that stayed up late. (acheadline.com)

JD Digits independently developed wearable Al bionic hands that can quickly identify and respond to myoelectric signals within 0.5 seconds, with an accuracy rate of nearly 100%. The bionic hand can realize multi-joint cooperative control and fine operation, as well as automatic operation through built-in intelligent perception module and Al algorithm. Based on this, the labor effciency of special groups was greatly increased by 50%. (eastmoney.com)

●普林斯顿大学发现不会耐药的“超级抗生素”

Princeton University finds a super antibiotic that won't resist drugs

近日，普林斯顿大学的一个研究小组在 Cell 杂志上发表报告称，他们 发现了一种具有双机制的抗生素 SCH-79797 ，如一支 “带毒的箭” 刺穿细菌的细胞壁，靶向破坏细胞内的叶酸，且几乎不会产生耐药性。（学术头条）

Recently, a team of researchers at Princeton University reported in the journal Cell that they have found a dual-mechanism antibiotic, SCH-79797, such as a "poisonous arrow" piercing through the cell wall of bacteria, targeting the destruction of folic acid in cells with little resistance.

●科学家：焦虑导致的头发变白现象可自行消失

Scientists: Hair graying caused by anxiety can go away on its own

据《每日邮报》报道，哥伦比亚大学研究人员发现，头发变白可能直接与焦虑有关，同时头发可以自己恢复颜色。试验过程证明，生活中焦虑程度变轻不仅可以中断头发变白过程，还能令这一过程倒转，头发可以恢复为最初的颜色。但头发变白现象只能是在不久之前发生的才可以。（俄罗斯卫星通讯社）

Researchers at Columbia University have found that hair going gray may be directly linked to anxiety and that it can regain its colour on its own, the Daily Mail reported. It turns out that lightening your anxiety in life not only interrupts the greying process, but also reverses it and returns hair to its original colour, yet this only happenes when graying was not too long ago.
