Tehran, Jul 1 As many as 19 people have been killed in an explosion and fire at a medical facility in Tehran.
A total of 19 people, including 15 men and 4 women, were killed in the explosion, the emergency services confirmed, RT reported citing KhabarOnline website.
According to a regional official, a gas leak caused the incident. Sputnik quoted a deputy head of Tehran police as saying to YJC news outlet that oxygen tanks exploded in the semi-basement of the clinic.
Boston, Jun 7: Dozens of scientists doing research funded by Mark Zuckerberg say Facebook should not be letting President Donald Trump use of the social media platform to spread both misinformation and incendiary statements.
The researchers, including 60 professors at leading US research institutions, wrote a letter to the Facebook CEO on Saturday asking that he consider stricter policies on misinformation and incendiary language that harms people," especially during the current turmoil over racial injustice.
The letter calls the spread of deliberate misinformation and divisive language the researchers' goal of using technology to prevent and eradicate disease, improving childhood education and reform the criminal justice system.
The researchers' mission "is antithetical to some of the stances that Facebook has been taking, so we're encouraging them to be more on the side of truth and on the right side of history as we've said in the letter, said Debora Marks of Harvard Medical School, one of three professors who organized the letter.
The other organisers are Martin Kampmann of the University of California-San Francisco and Jason Shepherd of the University of Utah.
All have grants from a Chan Zuckerberg Initiative program working to prevent, cure and treat neurodegenerative disorders including Alzheimer's and Parkinson's disease. The initiative is run by Zuckerberg and his wife, Priscilla Chan.
They said the letter had more than 160 signatories. Shepherd said about 10% are employees of Chan Zuckerberg foundations.
The letter objects specifically to Zuckerberg's decision not to at least flag as a violation of Facebook's community standards Trump's post that stated when the looting starts, the shooting starts after unrest in Minneapolis over the videotaped killing of George Floyd, a black man, by a white police officer.
The letter's authors called the post a clear statement of inciting violence.
Twitter had both flagged and demoted a Trump tweet using the same language.
The Associated Press emailed the Chan Zuckerberg Initiative press office for comment. It did not immediately respond.
Some Facebook employees have publicly objected to Zuckerberg's refusal to take down or label misleading or incendiary posts by Trump or other politicians. But Zuckerberg who controls a majority of voting shares in the company has so far refused.
On Friday, Zuckerberg said in a post that he would review potential options for handling violating or partially-violating content aside from the binary leave-it-up or take-it-down decisions I know many of you think we should have labeled the President's posts in some way last week, he wrote.
"Our current policy is that if content is actually inciting violence, then the right mitigation is to take that content down not let people continue seeing it behind a flag. There is no exception to this policy for politicians or newsworthiness.
Moscow, Aug 7: Russia will register its first vaccine against the coronavirus on August 12, Deputy Health Minister Oleg Gridnev said on Friday.
The vaccine has been developed jointly by the Gamaleya Research Institute and the Russian Defence Ministry.
"The vaccine developed by the Gamaleya centre will be registered on August 12. At the moment, the last, third, stage is underway. The trials are extremely important. We have to understand that the vaccine must be safe. Medical professionals and senior citizens will be the first to get vaccinated," Gridnev told reporters at the opening of a cancer centre building in the city of Ufa.
According to the minister, the effectiveness of the vaccine will be judged when the population immunity has formed.
Clinical trials of the vaccine began on June 18 and included 38 volunteers. All of the participants developed immunity.
The first group was discharged on July 15 and the second group on July 20.
Paris, Jul 20: Two coronavirus vaccine candidates have proven safe for humans and produced strong immune reactions among patients involved in separate clinical trials, doctors said on Monday.
The first trial among more than 1,000 adults in Britain found that the vaccine induced "strong antibody and T cell immune responses" against the novel coronavirus.
A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.
The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.
The authors of the studies said that they encountered few adverse side-effects from the vaccine candidates.
However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.
Co-author Sarah Gilbert from the University of Oxford said the results "hold promise".
"If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at large scale."
