Russia, North Korea to challenge US President Donald Trump overseas

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.

The Hague, Jun 22: Finding inner peace is crucial for the armed forces and yoga is a beautiful way to find the balance, Dutch Defence Minister Ank Bijleveld has said, thanking India for the "wonderful gift" to the world.

Yoga has been gaining global popularity in recent years for the many benefits it has on one's physiology, psychology and spirituality.

Bijleveld participated in the online International Yoga Day celebrations organised by the Indian Embassy here on Sunday.

"The minister thanked India for the wonderful gift of yoga to the world," a statement issued by the embassy said on Monday.

She said finding inner peace is crucial for a man and woman in uniform and yoga is a beautiful way to find the balance, it noted.

Bijleveld said yoga has formed a part of the training for the Dutch armed forces for the last 15 years and there are 130 yoga instructors.

The representatives of the Dutch Army joined by the Dutch Police personnel demonstrated their yoga skills as part of the online celebrations, the statement said.

The sixth International Yoga Day celebrations was streamed to 145,000 followers of the embassy's Facebook, Twitter, Instagram and YouTube channels as well as on its website. It was also streamed on the website of the non-profit foundation Stichting International Yoga Day.

Ambassador of India to The Netherlands Venu Rajamony inaugurated the celebrations. This was followed by Prime Minister Narendra Modi's video message and 3D animated videos of yoga with him.

The event was participated by a host of prominent Dutch and Indian personalities, including Ambassadors of various countries based in The Hague.

Dutch actress Afke Reijenga, extreme sportsman Wim Hof -- popularly known as 'The Iceman' and singers Charlie Dee and Anouk Maas were amongst the Dutch celebrities who participated in the event, the statement said.

Messages and artistic contributions by spiritual leader Sri Sri Ravi Shankar, internationally acclaimed flautist Pandit Hariprasad Chaurasia, violin maestro L Subramaniam, playback singers Kavita Krishnamurthy and Vijay Prakash, chess grandmaster Viswanathan Anand and film stars Raadhika, Sarathkumar and Bhumika Chawla featured in the programme.

Cricketer Suresh Raina, tennis stars Ramesh Krishnan and Rohan Bopanna, yoga guru and artist Bharat Thakur, Olympic ice skater Vishwaraj Jadeja and Michelin star chef Vikas Khanna also featured in the event.

The programme included a Kathak recital on 'Ayush' choreographed by Dutch choreographer Leo Spreksel and performed by eminent Kathak dancers Hari and Chetna with Sirisha.

It also showcased Hollywood and Bollywood celebrities who have made yoga a part of their lives.

Kensington (United States), May 20: The world cut its daily carbon dioxide emissions by 17% at the peak of the pandemic shutdown last month, a new study found.

But with life and heat-trapping gas levels inching back toward normal, the brief pollution break will likely be “a drop in the ocean" when it comes to climate change, scientists said.

In their study of carbon dioxide emissions during the coronavirus pandemic, an international team of scientists calculated that pollution levels are heading back up — and for the year will end up between 4% and 7% lower than 2019 levels.

That's still the biggest annual drop in carbon emissions since World War II.

It'll be 7% if the strictest lockdown rules remain all year long across much of the globe, 4% if they are lifted soon.

For a week in April, the United States cut its carbon dioxide levels by about one-third.

China, the world's biggest emitter of heat-trapping gases, sliced its carbon pollution by nearly a quarter in February, according to a study Tuesday in the journal Nature Climate Change. India and Europe cut emissions by 26% and 27% respectively.

The biggest global drop was from April 4 through 9 when the world was spewing 18.7 million tons (17 million metric tons) of carbon pollution a day less than it was doing on New Year's Day.

Such low global emission levels haven't been recorded since 2006. But if the world returns to its slowly increasing pollution levels next year, the temporary reduction amounts to ''a drop in the ocean," said study lead author Corinne LeQuere, a climate scientist at the University of East Anglia.

“It's like you have a bath filled with water and you're turning off the tap for 10 seconds," she said.

By April 30, the world carbon pollution levels had grown by 3.3 million tons (3 million metric tons) a day from its low point earlier in the month. Carbon dioxide stays in the air for about a century.

Outside experts praised the study as the most comprehensive yet, saying it shows how much effort is needed to prevent dangerous levels of further global warming.

“That underscores a simple truth: Individual behavior alone ... won't get us there,” Pennsylvania State University climate scientist Michael Mann, who wasn't part of the study, said in an email.

“We need fundamental structural change.”

If the world could keep up annual emission cuts like this without a pandemic for a couple decades, there's a decent chance Earth can avoid warming another 1.8 degrees (1 degree Celsius) of warming from now, study authors said. But getting the type of yearly cuts to reach that international goal is unlikely, they said.

If next year returns to 2019 pollution levels, it means the world has only bought about a year's delay in hitting the extra 1.8 degrees (1 degree Celsius) of warming that leaders are trying to avoid, LeQuere said. That level could still occur anywhere from 2050 to 2070, the authors said.

The study was carried out by Global Carbon Project, a consortium of international scientists that produces the authoritative annual estimate of carbon dioxide emissions. They looked at 450 databases showing daily energy use and introduced a measurement scale for pandemic-related societal “confinement” in its estimates.

Nearly half the emission reductions came from less transportation pollution, mostly involving cars and trucks, the authors said. By contrast, the study found that drastic reductions in air travel only accounted for 10% of the overall pollution drop.

In the US, the biggest pollution declines were seen in California and Washington with plunges of more than 40%.
