Youth held for posting objectionable pic of deity on social media  

New Delhi, Feb 7: The Supreme Court on Friday issued a notice to the Central government on a plea challenging the Constitutional validity of the Citizenship Amendment Act (CAA) and effective implementation of the Assam Accord.

A bench of Chief Justice of India (CJI) SA Bobde also sought Centre's response on the plea filed by Assam Social Justice Forum.

The petition sought appropriate directions for taking effective steps for the implementation of Assam Accord, 1985 in letter and spirit and for conservation and preservation of the of a distinct culture, heritage and traditions of the indigenous people of Assam.

The Assam Accord, 1985, had fixed March 24, 1971, as the cut-off date for deportation of all illegal immigrants irrespective of their religion.

The Bench also sought Centre's response on another fresh batch of pleas challenging CAA and tagged them along with other petitions pending in the matter.

One of the petitions, filed by the Association of Advocates from Maharashtra among others, sought to declare the Citizenship Amendment Act as discriminatory, arbitrary, and illegal and consequently set aside the impugned act as ultra-vires the Constitution of India.

On the other hand, over a hundred petitions have been filed in the apex court, for and against the amended citizenship law, which is facing opposition and protests across the country.

CAA grants citizenship to Hindus, Sikhs, Buddhists, Jains, Parsis and Christians who fled religious persecution in Afghanistan, Bangladesh, and Pakistan and took refuge in India on or before December 31, 2014.

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.
