US election 2016: Barack Obama tells voters 'the fate of the Republic rests on you'

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.

Oakland, Jun 2: Facebook employees are using Twitter to register their frustration over CEO Mark Zuckerberg's decision to leave up posts by President Donald Trump that suggested protesters in Minneapolis could be shot.

While Twitter demoted and placed a warning on a tweet about the protests that read, in part, that “when the looting starts the shooting starts,” Facebook has let it stand, with Zuckerberg laying out his reasoning in a Facebook post Friday.

“I know many people are upset that we've left the President's posts up, but our position is that we should enable as much expression as possible unless it will cause imminent risk of specific harms or dangers spelled out in clear policies,” Zuckerberg wrote.

Trump's comment evoked the civil-rights era by borrowing a phrase used in 1967 by Miami's police chief to warn of an aggressive police response to unrest in black neighborhoods.

On Monday, Facebook employees staged a virtual “walkout” to protest the company's decision not to touch the Trump posts according to a report in the New York Times, which cited anonymous senior employees at Facebook.

The Times report says “dozens” of Facebook workers “took the day off by logging into Facebook's systems and requesting time off to support protesters across the country." “I work at Facebook and I am not proud of how we're showing up.

The majority of coworkers I've spoken to feel the same way. We are making our voice heard,” tweeted Jason Toff, a director of product management at Facebook who's been at the company for a year.

Toff, who has a verified Twitter account, had 131,400 “likes” and thousands of retweets of his comment. He did not immediately respond to a message seeking comment on Monday.

“I don't know what to do, but I know doing nothing is not acceptable. I'm a FB employee that completely disagrees with Mark's decision to do nothing about Trump's recent posts, which clearly incite violence. I'm not alone inside of FB.

There isn't a neutral position on racism,” tweeted another employee, design manager Jason Stirman.

Stirman did not immediately respond to a request for comment on Monday. Sara Zhang, a product designer at the company, tweeted that Facebook's “decision to not act on posts that incite violence ignores other options to keep our community safe.

The policy pigeon holes us into addressing harmful user-facing content in two ways: keep content up or take it down.” “I believe that this is a self-imposed constraint and implore leadership to revisit the solution,” she continued. Zhang declined to comment to The Associated Press.

Representatives for Facebook did not immediately respond to messages for comment.

Twitter has historically taken stronger stances than its larger rival, including a complete ban on political advertisements that the company announced last November.

That's partly because Facebook, a much larger company with a broader audience,targeted by regulators over its size and power, has more to lose. And partly because the companies' CEOs don't always see eye to eye on their role in society.

Over the weekend, Twitter changed the background and logo if its main Twitter account to black from its usual blue in support of the Black Lives Matter protesters and added a #blacklivesmatter hashtag. Facebook did the same with its own logo on its site, though without the hashtag.

The Cambridge Analytica scandal is far from over. New explosive details leaked by a whistleblower shows that the extent of the rot is far deeper than previously thought.

An anonymous Twitter account, @HindsightFiles, has started releasing the documents, apparently on behalf of Brittany Kaiser, a former employee of the now defunct British data analytics and consulting company Cambridge Analytica.

"Democracies around the world are being auctioned to the highest bidder. We release the documents that explain how," reads the biography of the @HindsightFiles.

The document will reveal previously unreleased emails, project plans, case studies, negotiations and more spanning over 60 countries.

"Over the past two years I have given evidence to investigators, journalists and academics to analyse what happened at Cambridge Analytica, and how our data was used to influence democracies around the world. In the name of shedding light on these dark practices, I am releasing documents and emails in full for the public good," Kaiser, who worked with Cambridge Analytica from 2014 to 208, was quoted as saying.

"I do this to strengthen the case for data rights and enforcement of our electoral laws online globally. We should all be seeking more ethical digital future for ourselves and our children," added Kaiser who starred in the Oscar-shortlisted Netflix documentary "The Great Hack".

The details released so far includes links to material on the firm's activities in Malaysia, Kenya, Brazil and Iran, an addition to the John Bolton archive.

Over the next months, more than 100,000 documents relating to work in 68 countries are set to be released, according to a report in The Guardian.

More than one and a half year after the Cambridge Analytica scandal first became public, US regulators last month said that the now-defunct British data analytics and consulting company engaged in deceptive practices to harvest personal information from tens of millions of Facebook users for voter profiling and targeting.

According to Kaiser, the Facebook data scandal was part of a much bigger global operation designed to manipulate people in collaboration with governments, intelligence agencies, commercial companies and political campaigns.

The unpublished documents contain material that suggests the firm collaborated with a political party in Ukraine in 2017 even while under investigation as part of Robert Mueller's investigation into Russian interference in the 2016 US presidential election, said The Guardian report.

"There are emails between these major Trump donors discussing ways of obscuring the source of their donations through a series of different financial vehicles. These documents expose the entire dark money machinery behind US politics," Kaiser was quoted as saying.

Similar tactics were deployed in other countries that Cambridge Analytica operated in, including Britain, she claimed.

The files released by Kaiser suggest that Cambridge Analytica offered to help United Malays National Organisation (Umno), the party of Malaysia's Former Prime Minister Najib Razak, to influence the voting of 40 parliamentary constituencies in the 14th General Election (GE14) in 2013.

Umno, according to the leaks, requested the company to prepare a proposal to regain 13 seats, The South China Morning Post reported on Saturday.

In 2018, Razak claimed that he had never engaged Cambridge Analytica in any way.
