Washington, Jun 24: Twitter has once again flagged a tweet from US President Donald Trump which promoted violence by saying if protesters tried to set up an "autonomous zone" in Washington, DC they would be met with "serious force".

This is the fourth time Twitter has red flagged Trump's tweet for glorifying violence or violating its policies.

Trump has been critical of the "autonomous zone" in Seattle, an area occupied by protestors for much of this month.

"We've placed a public interest notice on this Tweet for violating our policy against abusive behaviour, specifically, the presence of a threat of harm against an identifiable group," Twitter's safety team tweeted late Tuesday.

Trump had tweeted: "There will never be an ‘Autonomous Zone' in Washington, D.C., as long as I'm your President. If they try they will be met with serious force!"

Twitter earlier labeled a video tweeted by him which mocked CNN as manipulated media.

According to Twitter, "this Tweet has been labeled per our synthetic and manipulated media policy to give people more context".

In May, Twitter labeled two Trump tweets that made false claims about mail-in ballots in California.

Twitter later labeled another Trump tweet glorifying violence in which he said, "when the looting starts, the shooting starts."

Facebook also removed a Trump campaign ad featuring a symbol used by Nazis for political dissenters, saying the ad violated its policies.

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.

Wellington, Jun 8: New Zealand lifted all domestic coronavirus restrictions on Monday after its final COVID-19 patient was given the all clear, with Prime Minister Jacinda Ardern revealing she danced around her living room when told about the milestone.

While strict border controls will remain in place, Ardern said restrictions such as social distancing and limits on public gatherings were no longer needed.

"We are confident we have eliminated transmission of the virus in New Zealand for now," she said in a televised address, saying Kiwis had "united in unprecedented ways to crush the virus".

The South Pacific nation, with a population of five million, has had 1,154 confirmed COVID-19 cases and 22 deaths.

There have been no new infections for 17 days and, until Monday, just one active case for more than a week.

Details of the final patient were not released for privacy reasons but it is believed to be a woman aged in her 50s who was linked to a cluster at an Auckland nursing home.

Ardern said the sacrifices made by New Zealanders, including a drastic seven-week lockdown that helped curb infection rates, had been rewarded now that there were no active cases in the country.

Asked about her reaction upon hearing the news, she replied: "I did a little dance" with baby daughter Neve.

"She was caught a little by surprise but she joined in, having absolutely no idea why I was dancing around the lounge."

New Zealand's move down to Level 1, the lowest rating on its four-tier virus response system, means nightclubs can operate without dance floor restrictions and theatres will reopen.

It also means sporting events can proceed with crowds in the stands, a change New Zealand Rugby (NZR) said offered its Super Rugby Aotearoa competition the opportunity to achieve a world first when it kicks off this weekend.

"We're incredibly proud, and grateful, to be the first professional sports competition in the world to be in a position to have our teams play in front of their fans again," NZR chief executive Mark Robinson said.

While many other sporting competitions around the globe have announced plans to restart, the vast majority will be played either with no crowds or with numbers severely restricted.

On a broader level, Ardern said easing restrictions would help New Zealand's economy.

"We now have a head start on economic recovery because at level one we become one of the most open, if not the most open, economies in the world," she said.

The prime minister said modelling showed the economy would operate at just 3.8 percent below normal at Level 1, compared with a 37 percent impairment at Level 4 lockdown.
