电子屏幕的蓝光可损害脑细胞和视网膜

Blue light from electronic screens can damage brain cells and the retina

一项发表在《衰老与疾病机理》的研究发现，每天接受蓝光照射的果蝇，会出现闹细胞和视网膜受损的情况，运动能力也受到影响。人类可以通过佩戴过滤蓝光眼镜等手段尽量减少蓝光对人体造成的不利影响。（新华社）

A study published in the journal aging and the mechanism of disease found that flies exposed to blue light every day suffered damage to their cells and retinas, as well as motor sills. Humans can minimize the harmful effects of blue light by wearing blue-filtered glasses. (xinhua) 

空气污染与孕早期流产风险有关

Air pllution is linked to the risk of miscarriage in early pregnancy

在学术期刊《自然》子刊Nature Sustainability最新上线的一篇论文中，中国北京的一支研究团队，考察了近9年时间里超过25万北京孕妇的临床数据，结合空气质量数据的分析，发现暴露于空气污染与增加孕早期流产风险有关。

In a paper recently published online by Nature Sustainability, a team of researchers in Beiing, China, examined clinical data of more than 250,000 pregnant women in Beijing over a nine-year period, combined with analysis of air quality data, and found that exposure to air pollution was associated with an increased risk of miscarriage in early pregnancy.

在对孕妇年龄、职业、周围气温等多项潜在的混杂因素做出控制后，分析结果表明，PM2.5、二氧化硫、臭氧和一氧化碳这四种空气污染物都是孕早期稽留流产的风险因素。（学术经纬）

After controlling for potential confounders such as age, occupation and ambient air temperature, the analysis showed that PM2.5, sulfur dioxide, ozone and carbon monoxide were all risk factors for miscarriage in early pregnancy. (academic background)

默克尔政府允许华为向德国提供5g产品

The merkel government alowed huawei to provide5g products to Germany

10月14日，德国《商报》报道称，该报提前拿到了德国电信监管机构——联邦网络管理局最新版电信网络安全草案。德国总理默克尔允许华为参与到该国的5G网络建设中，最初计划阻止华为进入德国市场的条款未出现在草案当中。

报道称，联邦网络管理局会在未来几天公布这一最新草案。在与企业和协会进行商讨之后，相关规定将于今年年末或明年年初生效。（观察者）

On October 14, the German newspaper Handelsblatt reported that it had obtained the latest draft of telecom network security from the German telecom regulator, the federal network administration. German chancellor Angela merkel allowed huawei to participate in the country's 5G network construction.

The federal cyber administration is expected to release the latest draft in the coming days, the report said. The rules will come into force late this year or early next year after discussions with businesses and asociations. (Observer)

武大樱花十月就开了

The cherry in Wuhan University blossoms in October

近几年武大秋天都有零星樱花开放，但像今年成簇绽放的情况还比较少见。这到底是什么原因造成的呢？武汉大学生命科学学院老师杜巍介绍：其实植物反季节开花是比较常见的，一旦合适的环境因子诱导出花原基的分化，加上水分养分条件适宜，就很容易出现反季开花的现象。光照对植物开花起到很重要的作用，春秋季光照时间长短有时很相似，所以就导致植物误判。（江苏新闻广播）

In recent years, there have been sporadic chery blossoms in autumn, but clusters like this time are relatively rare. What is the cause of this?Wu wei, teacher of  school of life science in Wuhan university introduced: in fact, it is common for plants to flower against the season. Once the appropriate environmental factors induced flower primal differentiation, plus water and nutrient conditions are appropriate, it is easy that flowers blossom against the season. Light plays a very important role in the flowering of plants, and the length of light in spring and autumn is sometimes very similar, leading to the misjudgment of plants. (jiangsu news broadcast)

量子波动速读

Quantum wave speed reading

因为一段充满节奏感的“读书”视频，量子波动速读突然“走红”网络。培训机构宣称，只要掌握了量子波动速读方法，就能在10分钟内阅读一本10万字左右的读物，并准确复述80%以上内容。更有甚者，阅读者只需一遍遍翻阅手中书本，就能阅读并理解其中内容，这在常人看来简直就是天方夜谭。尽管“量子波动速读”打着“量子”科学的宣传噱头，但只要人们稍加理性分析，便不难看穿其违反科学、有悖常识的荒诞与虚假。（央广网）

Quantum wave speed reading has suddenly gone viral thanks to a rhythmic video. The institute claims that anyone who has mastered the quantum wave speed reading method can read a book of about 10,000 words in 10 minutes and repeat more than 80 percent of the content accurately. What's more, a reader can read and understand a book simply by fipping through it over and over again. Despite the publicity stunt of "quantum wave speed reading", it is not difficult to see through the absurdity and falsehood of "quantum wave speed reading"， which violates science and contradicts common sense.

煤气罐着火如何处理

What to do about a gas cylinder fire

在液化气钢瓶阀门完好的情况下，首选是关阀，阀门关了火就灭了。网上流传的“先灭火、后关阀，否则会回火导致爆炸”的情况，在液化气钢瓶着火时是不会发生的。

如果液化气钢瓶横向倒地燃烧，钢瓶容易被火焰加热，到达一定温度后，瓶内的液化气受热膨胀，瓶体容易发生物理爆炸。（微博@中国消防）

If the valve of the liquefied gas cylinder is in good condition, the first choice is to close the valve. Once the valve closed, the fire will be put out. The "put out the fire first, then close the valve, or it will backfire and cause an explosion" situation will not happen actually.

If the liuefed gas cylinder is burmed hoiontally on the ground, the cylinder is easy to be heated by the flame. After reaching a certain temperature, the liquefted gas in the cylinder will be heated and expanded, and the cylinder body is easy to be physically exploded. (weibo @fre China)
