xy in the nearby Virgo galaxy cluster. It is 55 million light-years from Earth and has a mass 6.5 billion times that of the sun.

It was one example of the role that Tianma has played in international coordinated

observations. Its super sensitivity has made its observations useful as a reference by which other parti

cipants in the network can adjust their data, according to the Shanghai Astronomical Observatory.

“Tianma elevated the image quality of the EAVN, by about 50 percent, making a great co

ntribution to the research on extreme objects in the universe, such as black holes,” Shen said.

A key task of the campaign is to complete a survey of the threat of dust pois

oning, covering industries including mining, metallurgy and building materials by the end

of 2020, and to hold companies accountable for preventing the hazard, a commission document said.

haul working conditions, and will ask local authorities to shut down those that cannot improve.

The campaign aims for more rigorous inspections of high-dust employers and to punish those who violate laws and regula

tions. It will also urge employers to sign contracts with their employees and join occupational injury insurance.

a simple inspection at ports of entry. The administration

was disestablished in the latest government reshuffle and quara

ntine management functions were merged into the General Administration of Customs.

With a rising number of inbound foreign travelers and Chinese students returning home wit

h pets in tow, the administration issued the new rule in January to facilitate entry.

Shanghai Customs inspected 25 cats and 15 other pets at its ports of entry between May 1 and May 5. Twenty-seven of them were all

owed in after on-site inspections. Eleven were put under quarantine, and two were sent back to their original co

untry or region due to the lack of quarantine reports and rabies antibody test results.

Last year alone, 1,577 pets-822 dogs and 755 cats-entered Shanghai from overseas, customs data show.

Shanghai Customs has been publicizing information on the new regulations throu

gh various channels to passengers, including cooperating with more than 60 air carriers, it said.

It is reported that the IS terrorist organization has clai

med it was behind the horrific attacks. Yet whoever the perpetrators, the attacks on innoc

ent people should be condemned in the strongest terms, and those responsible arrested and punished.

Since Sri Lanka has been facing some political and e

conomic problems, and increasingly acute social conf

licts for the past few years, the attacks seem to reveal not just sectarian disputes but also cer

tain people’s dissatisfaction with the situation in the island nation, and the rest of South Asia.

The motive behind the attacks could be helplessness and desperation of certain sections of Muslims in South Asia.

The rise of Islamic extremism has to some extent fueled the rise of white supremac

ist groups in the United States and some European countries. Perhaps the conflict between Islamic extremism and

the anti-Muslim forces today is greater than that immediately after the Sept 11, 2001, attacks in the US.

And the rising tensions in South Asia and other regions should prompt govern

ments to take sound measures to prevent the spread of extremism inside their borders.、

A threat to the viability of the current WTO dispute settlement system is the unilateralism and

protectionism of the United States. Specifically, this mechanism is in crisis because the Unit

ed States has prevented the appointment of new judges to the appellate body. Experts have warned that if th

e appellate body were to shut down because of a lack of judges, global trade governance will be put back 20 years.

Of course the WTO also needs to continually reforming itself so that it can keep up w

ith the times, and many countries have put forward relevant suggestions. For instance, the European Uni

on has released a paper putting forth ideas for a comprehensive modernization of the WTO, and the United States, Eur

ope, and Japan have together submitted a their own proposed reforms. And in November last year, China ann

ounced that it supported necessary reforms of the WTO and raised five proposals that aim to firmly uphold the rules-ba

sed multilateral trading system, resist protectionism, and let the WTO play a bigger role in world trade.

Her announcement that she was asking for a three-month

  delay caused uproar in the chamber.

The opposition Labour Party accused her of “blackm

ail, bullying and bribery” in her attempts to push her deal through, and one

prominent Brexit supporter in he

r own Conservative Party said seeking a delay was “betraying the British people”.

  Britain voted in 2016 to leave the EU by 52 percent to 48 – a decision that has

split the country, opening up divisive deb

ates over the future of the economy, Britain’s place in the world and the

nature of Britishness itself.

  A European Commission document seen by Reuters said the delay should

either be several weeks shorter, to avoid a clas

h with European Parliament elections in May, or last at least until the end of the

year, which would oblige Br

itain to take part in the elections – something that May said was not in Britain’s interest.

Lack of sleep among children and teenagers deserves high

attention, because it can seriously affect their health and growth,” she said. Such a group should sleep at least eight hours a day, she added.

Zhao Zhongxin, a professor specialized in treating sleep disorders

at Shanghai Changzheng Hospital, said getting adequate sleep is very important.

“Sleep promotes growth, protects the brain and improves the immune system,” he said. “Long-term deprivation of sleep will

bring risks of diseases and conditions such as dementia and cause lasting health damage.”

Wang Guanghai, a member of the Chinese Sleep Research Society and a psychological consultant, said the exces

sive use of electronics products in China is depriving children and teens of sleeping time.

“Some of them use tablets for more than four hours a day,” he said. “It has become a serious problem that affects minors’ health.”
