Budget shocker: Modi govt proposes tax on non-taxpaying NRIs

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.

Bengaluru, May 20: A mysterious "boom" heard in large parts of Bengaluru this afternoon left residents of the city and social media users puzzled. While the source of the sound is being investigated, the Indian Air Force (IAF) indicated that it could be the result of "routine test flights that necessitate going supersonic a times".

The sound was heard from as far as the Bengaluru airport in Devanahalli to the IT hub of Electronic City 54 km away. It was also heard in Kalyan Nagar in east Bengaluru, central Bengaluru's MG Road and areas such as Marathahalli, Whitefield, Sarjapur and Hebbagodi.

IAF said no aircraft of training command was flying in the area. "However, ASTE (Aircraft and Systems Testing Establishment) and HAL (Hindustan Aeronautics Limited) could have been undertaking their routine test flying, which necessitates going supersonic at times. These are done well beyond the city limits in specified sectors. However, considering the atmospheric conditions and reduced noise levels in the city during these times, the aircraft sound may become clearly audible even if it happened way out from the city," said the air force statement.

Many people had speculated that the sound could have been caused by a fighter jet such as a Mirage 2000.

"We have also asked the Air Force Control Room to check if it was a jet or supersonic sound. Bengaluru police are awaiting confirmation from the Air Force," Bengaluru police commissioner Bhaskar Rao said in a statement.

It was not an earthquake, Karnataka's state disaster monitoring centre had tweeted earlier.

"Earthquake activity will not be restricted to one area and will be widespread. We have checked our sensors and there is no earthquake activity recorded today," the Karnataka State Natural Disaster Monitoring Centre said, quoting its director Srinivas Reddy.

"The activity reported in Bengaluru is not due to an earthquake. The seismometers did not capture any ground vibration as generally happens during a mild Tremor. The activity is purely a loud unknown noise," the agency tweeted.

#Bangalore and #BangaloreBoom was among the top trends on Twitter this afternoon.

"We are trying to ascertain the source of the noise," a senior police officer said. "In Whitefield area, we have searched on the ground and so far, there is no damage to any property," he added. There were no calls to the police control room reporting any damage.
