World’s first COVID-19 vaccine production line wins approval

China made another breakthrough in battling the coronavirus pandemic, with China National Biotec Group (CNBG) announcing Wednesday that an inactivated COVID-19 vaccine production workshop of its affiliated Beijing institute of biological products, the first and largest of its kind in the world, has passed national examination.

The facility was granted a production certificate and it is now available for use, CNBG, an affiliate of the state-run China National Pharmaceutical Group, said in a statement sent to the Global Times. 

The Beijing institute took only two months to finish building the facility on April 15. Related government departments conducted a thorough biosecurity examination of the production workshop in July, and concluded the facility met national standards, and could go into operation for mass production of COVID-19 vaccines, read the statement. 

After the Beijing manufacturing workshop and another production facility belonging to CNBG’s Wuhan institute of biological products begin operations, CNBG will be capable of ensuring an annual capacity of 220 million doses of vaccines, according to its developer.

The 220 million doses are large to first immunize medical staff and personnel working at airports and border checkpoints, Tao Lina, a Shanghai-based vaccine researcher, told the Global Times Wednesday. 

“It is possible that China could have a COVID-19 vaccine as early as the end of October as some domestically made COVID-19 vaccines have entered phase three clinical trials and needs about a month to observe their effects on samples,” Tao said. 

After securing a certain amount of vaccine for China’s strategic reserves, exports can be considered, Tao noted, adding countries such as the Philippines and Brazil are potential destinations. 

Sinopharm is launching the fourth major COVID-19 vaccine trial in Brazil and will seek regulatory approval soon, Reuters reported on July 30. 

The company’s candidate vaccine is already being tested in the United Arab Emirates with 15,000 local volunteers, including UAE nationals and expatriates there, since middle July.

In another major step, German firm BioNTech and its Chinese partner Shanghai Fosun Pharmaceutical announced Wednesday that 72 trial participants have been dosed with BNT162b1, a COVID-19 vaccine candidate based on BioNTech’s mRNA technology, following the Chinese regulators’ examination and approval. The two firms are jointly developing the coronavirus vaccine candidate in China too.

In another sign of progress, scientists from the Hong Kong and Macao special administrative regions announced Monday a breakthrough in the development of a recombinant COVID-19 vaccine, envisioning the vaccine’s mass production to be feasible at a low cost in the future.

A spokesperson for Ministry of Industry and Information Technology said in late July that China has 13 firms that have begun capacity building for COVID-19 vaccines, and nine have been approved to start clinical trials.

Four of the nine firms are pushing for an inactivated vaccine technical route, three are focusing on nucleic acid vaccines, one is based on adenovirus vector vaccines and one has opted for recombinant protein vaccines, media reports say.

The nation’s advances in the research and manufacture of COVID-19 vaccines have been translated into remarkable gains in vaccine-related stocks on the A-share market. 

Shares in the Shanghai-listed Fosun Pharmaceutical soared by the 10 percent daily trading limit to close at 74.01 yuan Wednesday, having rallied 182 percent for the year. 

In another sign that the nation’s capital market is expected to fund its biotech capability, Hong Kong-traded CanSino Biologics is set to debut in the STAR Market tech board in Shanghai , making the vaccine maker the first dual-listed vaccine company in China .

CanSino Biologics revealed in late June that a recombinant novel COVID-19 vaccine it developed with a military research team has been granted a special one-year military drug approval.

A giant katydid with a body length of 8cm

Sichuan Chengdu Hua Xi Insect Museum curator Zhao Li recently found a giant katydid 螽(音“中”)斯 with a body length of 8cm in Qingcheng Mountain 青城山, which is twice as big as the common katydids of Sichuan past, refreshing the record of Sichuan’s largest katydid.

  ”Its wings look very broad from the front and back, more like a leaf,” The katydid is the largest katydid in Sichuan, and the largest katydid in China is the giant leaf katydid 巨拟叶螽

from Xishuangbanna 西双版纳 , which can be more than 12.5cm in length.

  Zhao Li introduced, this katydid belongs to the subfamily Pseudophyllinae of Arabidopsis katydids, belongs to the insectoid Insecta Orthoptera Orthoptera katydids Tettigoniidae. currently the world records 19 families 260 genera (subgenera) 998 species (subspecies), mainly distributed in the neotropics, paleotropics and subtropics. “A total of 16 genera and 39 species (subspecies) have been recorded in the Chinese subfamily Orthoptera Tettigoniidae.” “All the katydids found in the Sichuan region in the past were small and medium-sized species, the largest being the large katydid that is no more than 7cm in length,” Zhao Li said, “This mountain subleaf katydid has a very fat abdomen, while the abdomen volume of the large katydid with a length of 7cm is only a fraction of its size.” Compared to the carnivorous katydids, the mountain subleaf katydid is a ‘gentle giant’ that is vegetarian and catches insects.” Zhao Li said that when reared so far, it has been found that it not only feeds on the leaves of the Nanmu tree 楠木树 , but also the leaves of plants in the chitin 壳斗科 family.

  Nocturnal katydids lay eggs on tree trunks.

  ”This mountain subleaf katydid is nocturnal and hides in the canopy layer during the day and only goes to the trunk at night to lay its eggs, so its presence is rarely known.” When Zhao Li found it, it was on the trunk of a Nanmu tree , using a spawner to burrow into the bark to lay its eggs.

  Nanmu is a very tall tree, reaching up to more than 30 meters in height and up to 1 meter in diameter at breast height. “Because this katydid mimics the leaves of the Nanmu tree, it hides in the tree during the day and won’t be noticed.”

  Zhao Li lamented that the giant katydid has not been found because it is too rare, “I’ve seen its limbs before in Jiulonggou九龙沟 and Xiling Snow Mountain 西岭雪山 . All of them are wings or heads left over from being eaten by birds.”

  It is known that katydids lay their eggs on the shallow surface of the soil and some larvae die if they can’t get out of the soil, so will the mountain leaf katydid survive if it lays its eggs in the bark of a tree?

  ”It has a very specific way of laying its eggs and I think the purpose of laying its eggs in the bark is to keep them moist. Also the bark effectively protects its eggs from being damaged by other things.” Zhao Li said the insects have a low survival rate, so they use a strategy of laying large numbers of eggs. “Most katydids have a short lifespan, hatching in the spring and dying at the end of October. However, with artificial warmth, some species of katydids can live until the following spring.”

China builds world’s first high-speed train passing through sea tunnel

China is building the world’s first high-speed train that can travel through a sea tunnel at a speed of 350 kilometers per hour in Shantou Bay, South China’s Guangdong Province.

The 163-kilometer-long railway, which includes a 9,781-meter-long tunnel, has officially entered the substantive construction stage, with an investment estimated to be at 11 billion yuan ($1.6 billion), the China Central Television reported Tuesday. 

According to the report, the tunnel will pass through 17 fault rupture zones in a magnitude-8 earthquake zone, of which eight are active faults, the first underwater tunnel of its kind anywhere in the world.

Most parts of the tunnel are located in high water pressure areas. As a result, construction personnel have to adopt measures to ensure that the tunnel structure is safe, waterproof and reliable, and that operating costs are controllable.

Ant Group, ByteDance become world’s highest-valued unicorns: Hurun report

By the end of March China had the world’s second-highest number of unicorns, private companies whose valuations exceed $1 billion, according to the Hurun Global Unicorn Index 2020 list released by the Hurun Research Institute on Tuesday.

Among the world’s 10 highest-valued unicorns, six are Chinese companies. Alibaba’s financial arm Ant Group is the world’s largest unicorn with a valuation of $1 trillion. ByteDance, which has recently been facing a crackdown from the Trump administration, is the second highest with a valuation of $560 billion, the list showed.

Chinese tech firms Didi Chuxing and Kuaishou were also among the top 10. 

In total, there are 586 unicorn companies in the world, up 82 from the same time last year. 233 are US companies, making it the country with the most unicorns. China is in second with 227, followed by the UK and India. 

Unicorns in China and the US collectively account for about 80 percent of the world’s total.

The list also showed that Beijing is the “capital” of global unicorns, being home to 93, largely outnumbering San Francisco’s 68. 

Watch out for those Chinese stocks, ready for a prolonged surge.

There will only be six times in the 21st century

月亮何时最圆?常会听到的一种说法是“十五的月亮十六圆”,但是在庚子鼠年的农历六月里,十五的月亮却是“十四圆”,最圆时刻出现在8月3日23时59分。天文专家表示,“十五的月亮十四圆”这种现象比较罕见。21世纪这100年中,这种情况仅会出现6次。

  中国天文学会会员、天津市天文学会理事史志成介绍说,每逢农历初一,我们看不到月亮,叫“新月”,也叫“朔”;到了农历十五左右,我们可以看到圆圆的月亮,称为“满月”,也叫“望”。

  根据农历历法规定,“朔”所在这一天为每月初一。但同是初一,“朔”可能发生在凌晨,或者上午、下午,也可能发生在晚上,而且每个朔望月本身也有长有短。这样,月亮最圆时刻的“望”最早可发生在农历十四的晚上,最迟可出现在农历十七的早上。但由于“朔”一定在农历的每月初一,“朔”之后平均起来要再经过14天18小时22分才是“望”,所以月亮最圆时刻的“望”以出现在农历十五、十六这两天居多,其中又以出现在农历十六为最多。

  在21世纪的这100年中,“满月”出现在农历的十七、十六、十五和十四的次数统计结果显示,出现“满月”的次数共1241次。其中,出现次数最多的是农历十六,有579次;其次是农历十五,有468次;再次是农历十七,有188次;次数最少的是农历十四,仅有6次。
