Cops force Muslim woman to remove burqa at Yogi Adityanath's rally

Hyderabad, Jun 20: IAF Chief Air Chief Marshal RKS Bhadauria on Saturday said that the force is well prepared and suitably deployed to respond to any contingency and it will never let the sacrifice of the bravehearts of Galwan go in vain.

"It should be very clear that we are well prepared and suitably deployed to respond to any contingency. I assure the nation that we are determined to deliver and will never let the sacrifice of the braves of Galwan go in vain," IAF Chief Air Chief Marshal Bhadauria said here.

Bhadauria was speaking at the Combined Graduation Parade (CGP) at Air Force Academy in Hyderabad.

His remarks come days after 20 Indian soldiers lost their lives in the violent face-off on June 15-16 during an attempt by the Chinese troops to unilaterally change the status quo during the de-escalation in eastern Ladakh.

Speaking about the current border situation with China, he said: "We are aware of the situation, be it on LAC or beyond, be it their air deployments, their posture and kind of deployments. We've full analysis and we have taken necessary action that we need to take to handle any contingency that may come up."

"We are monitoring all the moments and we are aware of the full situation," he added.

He further said that in spite of the "unacceptable Chinese action" at Galwan Valley in eastern Ladakh, which claimed lives of 20 Indian Army personnel, efforts are underway to ensure that the current situation at the Line of Actual Control (LAC) is resolved peacefully.

He asserted that the IAF is determined to deliver and the development at the LAC in Ladakh is a small snapshot of what the force is required to handle at short notice.

The IAF Chief further appealed to people to join him in paying tribute Colonel Santosh Babu and his brave men who made the sacrifice while defending the LAC in Galwan valley.

"The gallant actions in a highly-challenging situation have demonstrated our resolve to protect India's sovereignty at any cost," the Indian Air Force (IAF) chief said.

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.
