Twitter suspends over 70 million accounts in 2 months: Washington Post

Bengaluru, Jul 7: Twitter Inc suspended more than one million accounts a day in recent months to reduce the flow of misinformation on the platform, the Washington Post reported.

Twitter and other social mediaplatforms such as Facebook Inc have been under scrutiny by US lawmakers and international regulators for doing too little to prevent the spread of false content.

The companies have been taking steps such as deleting user accounts, introducing updates and actively monitoring content to help users avoid being a victim to fake content.

Twitter suspended more than 70 million accounts in May and June, and the pace has continued in July, the Post reported on Friday, citing data it obtained.

"It's hard to believe that 70 million accounts were affected when Twitter has only 336 million monthly active users (MAU)," Wedbush analyst Michael Pachter said.

Twitter's MAU is expected to grow nearly 3 per cent to 337.06 in the second quarter, according to Thomson Reuters.

"My guess is that a large number of these suspended accounts were dormant ... it should have little impact on the company," Pachter told Reuters.

If the 70 million were mostly active accounts, the affected accounts would have been "screaming bloody murder", added the analyst.

According to a Washington Post source, however, the aggressive removal of unwanted accounts may result in a rare decline in the number of monthly users in the second quarter.

"Due to technology and process improvements during the past year, we are now removing 214 percent more accounts for violating our spam policies on a year-on-year basis," the company said in a blog post last month.

In May, it identified and challenged more than 9.9 million "potentially spammy" or automated accounts per week, compared with 6.4 million in December 2017.

Shares of Twitter fell marginally to $46.50 after the bell on Friday.

Canadian researchers developing DNA vaccine against COVID-19

March 28,2020

Canadian researchers are developing a DNA vaccine for SARS-CoV-2, the coronavirus that causes COVID-19 and has currently infected nearly 5,00,000 people worldwide and crippled the global economy.

Entos Pharmaceuticals, a health-care biotechnology company headed by a University of Alberta researchers, develop new therapeutic compounds using the company's proprietary drug-delivery platform and has begun manufacturing vaccine candidates against the novel coronavirus.

"Given the urgency of the situation, we can have a lead candidate vaccine within two months. Once we have that it's a race to get it into clinical trials," said John Lewis, CEO of Entos and a Professor at the University of Alberta in Canada.

Lewis said in comparison to a traditional vaccine, DNA-based vaccines hold several advantages.

Nucleic acids are introduced directly into the patient's own cells, causing them to make pieces of the virus--tricking the immune system into mounting a response without the full virus actually being present, the researcher said.

According to the company, the approach is recognised as being easier to move into large-scale manufacturing, offers improved vaccine stability and works without needing an infectious agent.

In the current absence of a vaccine for COVID-19, several companies around the world are mounting efforts to begin similar work.

The first clinical trial using a DNA-based vaccine developed by Moderna Inc.in the US on March 13.

Their approach allows for antibodies to be made in the human trial volunteers against a specific protein on the surface of the coronavirus that lets the virus enter human cells.

The hope is that the antibodies will stop the interaction.

Though this approach is designed to be effective against COVID-19 specifically, Lewis said Entos is taking a different tack.

The company plans to use plasmid DNA to amplify the production of key coronavirus surface and structural proteins with each injection, with an eye to the bigger picture.

"Many of the structural proteins in the virus are pretty well conserved across all the coronaviruses, including SARS and MERS," said Lewis.

"We're hoping that if we express more of the structural proteins that are common to most coronaviruses, we can inhibit the current COVID-19, and also potentially protect against all coronaviruses both past and future," Lewis added.

To move the project forward quickly, the company is seeking financial support from both provincial and federal levels of government.

"We have the opportunity to save a lot of lives, and I think it's really upon us and governments to find solutions for that," Lewis said.
