Face it
In much of the western world, governments now require people to wear masks when they are in crowded public spaces. That is good news, for masks could both save lives and allow people to get back to work. And to help economies restart safely, government should require people to wear face coverings in crowded public spaces.
People think of masks as something protecting them from dirty things in the air. But in the case of COVID-19, their more important job is to protect others from an infected wearer. That is because of one of the unusual characteristics of this disease: it seems likely that infection by people who have not, or not yet, developed symptoms(症状) makes up about a third to a half of the cases. So even if everybody with symptoms stays at home, the virus will still spread. Masks block the respiratory droplets(呼吸道飞沫) that carry the virus, so make risky situations safer.
There are signs that masking is useful. Even home-made face coverings can block droplets.
Experiments show that a piece of cloth over the mouth and face can block 60% of droplets—not as good as a medical mask, but much better than nothing.
East Asian countries’ success in controlling the disease argues in favour of masks. Wearing masks to protect against pollution or disease is common there, so people covered their faces as soon as they were informed of COVID-19. In the West, mask-wearing is alien. And in all of the countries where mask-wearing is common practice, the epidemic (流行病) was quickly controlled. This is not unquestionable evidence in favour of masks. Other factors distinguish those mask-wearing countries from bare-faced Western nations: some, such as China and South Korea, have strict track-and-trace systems and carry out mass coronavirus testing.
Yet the combination of this natural global experiment, laboratory studies and asymptomatic transmission(无症状传播) suggests that masks can help keep people safe. Lockdown destroys economies. Social distancing damages them. Masks cost next to nothing. They will not by themselves stop an epidemic. Hand-washing, track-and-trace systems and widespread testing are all crucial, too. But masks can do their bit to protect people and rebuild economies.

3 . Improve Cloud Security
Sensitive customer data has constantly been found exposed on cloud servers without password protection. To ease the problem, database software makers have been trying to make security easier for cloud database managers. At the Enigma Conference in San Francisco, Kenn White, a security manager at database software maker MongoDB, will describe a new technique, called field level encryption, to make data safer on the cloud.
Field level encryption works by scrambling data before it’s sent to a cloud database and rearranging it in order when the data is needed for use. The promise of the product is to protect the contents of a cloud database, even if bad guys access it.
MongoDB’s new feature comes as more and more companies move user data to cloud servers, rather than run their own costly data centers. It was predicted that cloud computing would be a $214 billion industry by the end of 2019. That would be up more than 17% from 2018, when it was $182 billion.
Companies have rushed to the cloud without understanding all of the possible security consequences. Many companies have left countless databases exposed, revealing personal data. A database containing details about who lives in 80 million US households was left unprotected in 2019, just like the data on Facebook users.
Database managers want to store their data in an unreadable form, but they also want to be able to find specific pieces of information in the database with a simple search term. For example, someone might want to look up health care patients by their Social Security numbers, even if those numbers are stored as random characters. To make this possible, field level encryption lets database managers encrypt a search term on their machine and send it to the database as a query. The database matches the encrypted version of the search term with the record it’s storing and then sends it back to you.
This approach only works with specific kinds of data. For example, field level encryption isn’t useful for long text entries, like notes in a patient’s medical chart, because you can’t search for individual words.
Still, for data like account numbers, passwords and government ID numbers, field level encryption protects data and maintains a usable database.
Most importantly, White said, it’s simple to set up. Database managers turn it on with a one-time configuration change when they set up the database. “That’s really powerful,” he said in an interview.

4 . Huang Danian, the well-known Chinese geophysicist, was born in 1958 in Guangxi, China. As a keen and able student, Huang went to the UK in 1993 to further his studies.
By the time Huang moved back to China in 2008, he had been living and working in the UK for 15 years. He had a good job and a life there, but he gave it all up to return to home driven by the idea that he needed to contribute to his country. As one of the world’s leading experts in deep earth exploration technology, Huang was invited to participate in the “Thousand Talent” programme. He took up a position at Jilin University, Changchun.
Huang was named lead scientist on China’s deep earth exploration programme, developing advanced cameras that can see through the Earth’s crust(外壳) so that it can be analysed without having to dig into it. He set up an advanced lab, sometimes paying for equipment with his own money. Some described him as a “lunatic” (a “madman”), but this passion and drive enabled Huang to push forwards China’s deep earth exploration technology into a world-leading position. Huang’s devotion contributed to China’s lunar probe(月球探测器) Yutu being landed on the moon in 2013 and the launch of the spacecrafts Shenzhou-11 and Tiangong-2 in 2016.
Huang's health also paid the price for his commitment to his work. He began having fainting fits(昏厥) in 2012, but paid them little attention, stating he did not have time to go to see a doctor— his work always came first. In November 2016, Huang fainted and was taken to hospital, where he was diagnosed with cancer. The disease was so advanced that he had just a couple of months to live.
Like the true scientist he was, Huang never gave up, but always tried to push forwards. Even from his hospital bed, he continued his work, writing letters of reference for his colleagues and replying to questions from his students. Huang died in January 2017, aged just 58. More than 800 people attended his funeral to celebrate a life that burned so bright, but was so short.
