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.

Washington, Jan 10: It is “highly likely” that Iran shot down the civilian Ukrainian jetliner that crashed near Tehran late Tuesday, killing all 176 people on board, U.S., Canadian and British officials declared Thursday.

They said the fiery missile strike could well have been a mistake amid rocket launches and high tension throughout the region.

The crash came just a few hours after Iran launched a ballistic attack against Iraqi military bases housing U.S. troops in its violent confrontation with Washington over the U.S. drone strike that killed an Iranian Revolutionary Guard general. The airliner could have been mistaken for a threat, said four U.S. officials, speaking on condition of anonymity to discuss sensitive intelligence.

Canadian prime minister Justin Trudeau, whose country lost at least 63 citizens in the downing, said in Toronto: “We have intelligence from multiple sources including our allies and our own intelligence. The evidence indicates that the plane was shot down by an Iranian surface-to-air missile.”

Likewise, U.K. prime Minister Boris Johnson and Australian prime minister Scott Morrison offered similar statements. Morrison also said it appeared to be a mistake. “All of the intelligence as presented to us today does not suggest an intentional act,” he said.

The assessment that 176 people were killed as collateral damage in the Iranian-U.S. conflict cast a new pall over what had at first appeared to be a relatively calm aftermath following the U.S. military operation that killed Iranian Gen. Qassem Soleimani.

At the White House, U.S. president Donald Trump suggested he believed Iran was responsible for the shootdown and dismissed Iran's initial claim that it was a mechanical issue with the plane.

“Somebody could have made a mistake on the other side.” Trump said, noting the plane was flying in a “pretty rough neighborhood."

New Delhi, Jan 29: The Supreme Court on Wednesday dismissed the plea by Mukesh Kumar Singh, one of the four death row convicts in the Nirbhaya gang rape and murder case, challenging the rejection of his mercy petition by the President.

A three-judge bench headed by Justice R Banumathi said that expeditious disposal of mercy plea by the President doesn't mean non-application of mind by him.

The court also said that alleged sufferings in prison can't be grounds to challenge the rejection of mercy petition.

The bench said all relevant material including judgments pronounced by trial court, high court and Supreme Court were placed before the President when he was considering the mercy plea of the convict.

The bench also comprising justices Ashok Bhushan and A S Bopanna rejected the contentions of the counsel appearing for Singh that entire materials of the case were not placed before the President when he was considering his mercy plea.

The bench, while referring to two files placed before it by the Centre on Tuesday, said that as per the January 15 covering letter which was sent by the Delhi government to the Ministry of Home Affairs, all relevant documents were sent.

The bench noted that detailed judgements of trial court, high court and the Supreme Court, curative petition filed by Singh, his past criminal history and his family background were sent to the Home Ministry by the Delhi government.

"All the documents were taken into consideration by the President while rejecting the mercy petition," the bench said.

The bench also dealt with submissions advanced by the convict's counsel, who had argued that the mercy plea was rejected at "lightning speed".

The bench said that if a mercy petition is expeditiously dealt with, it cannot be assumed that it has been adjudicated upon in a pre-conceived mind.
