Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

The Central Board of Secondary Education (CBSE) has rationalised the syllabus for classes IX to XII for the academic year 2020-21 by up to 30 per cent to make up for academic loss caused due to COVID-19, Union HRD Minister Ramesh Pokhriyal 'Nishank' announced on Tuesday.

"Looking at the extraordinary situation prevailing in the country and the world, CBSE was advised to revise the curriculum and reduce course load for the students of classes IX to XII.

"To aid the decision, a few weeks back I also invited suggestions from all educationists on the reduction of syllabus for students and I am glad to share that we received more than 1.5K suggestions. Thank you, everyone, for the overwhelming response," Nishank tweeted.

"Considering the importance of learning achievement, it has been decided to rationalize syllabus up to 30 per cent by retaining the core concepts," he added.

New Delhi, Feb 20: Microsoft has begun testing its free open-source software called "ElectionGuard" in a small Wisconsin town in the US that aims to make voting more secure, verifiable and efficient.

"ElectionGuard" will enable end-to-end verification of elections, open results to third-party organisations for secure validation, and allow individual voters to confirm their votes were correctly counted.

It enables government entities, news outlets, human rights organisations or anyone else to build additional verifiers that independently can certify election results have been accurately counted and have not been altered, according to the company.

The software would create a paper trail and assure voters their votes were properly tallied.

"On Tuesday, Fulton residents are using the technology while choosing who will join the local school board and hold a seat on Wisconsin's state Supreme Court," reports CNBC.

With the test, the company aims to see if voters like the experience and make sure everything works fine.

In May last year, Microsoft CEO Satya Nadella announced "ElectionGuard".

According to Tom Burt, Corporate Vice President, Customer Security and Trust, voting system manufacturers will be free to build ElectionGuard into their systems in a variety of ways.

"These are exciting steps that enable individual voters to confirm their vote was properly counted, and assures those voters using an ElectionGuard system of the most secure and trustworthy vote in the history of the US," Burt said in a recent blog post.

"ElectionGuard" is not intended to replace paper ballots but rather to supplement and improve systems that rely on them, and it is not designed to support internet voting.

The software provides each voter a tracker with a unique code that can be used to follow an encrypted version of the vote through the entire election process via a web portal provided by election authorities.

During the process of vote-casting, voters have an optional step that allows them to confirm that their trackers and encrypted votes accurately reflect their selections.

But once a vote is cast, neither the tracker nor any data provided through the web portal can be used to reveal the contents of the vote.

After the election is complete, the tracker codes can be used by voters to confirm that their votes were not altered or tampered with and that they were properly counted, said Microsoft.

On the security front, "ElectionGuard" uses something called homomorphic encryption - which enables mathematical procedures "like counting - to be done with fully encrypted data".
