Al-Qaeda 'ideologically inclined' to carry out attacks in India: UN report

New Delhi, Mar 2: The Supreme Court on Monday dismissed a curative petition filed by convict Pawan Kumar Gupta who was sentenced to death in the 2012 Nirbhaya gang rape and murder case.

A five-judge bench headed by Justice N V Ramana said that no case is made out for re-examining the conviction and the punishment of the convict.

Other members of the bench were justices Arun Mishra, R F Nariman, R Banumathi and Ashok Bhushan.

May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

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.
