Padma Vibhushan for Ambani, Shri Shri, Rajini; Bhushan for Anupam Kher, Sania

New Delhi, Feb 1: The budget is a little more demanding of the non-resident Indian. Firstly, to be categorized a non-resident, an Indian now has to stay abroad for 240 days, against 182 previously. In other words, an Indian national, to claim the non-resident status, can’t stay in India for 120 days or more in a year.

“We've made changes in Income Tax Act where if an Indian citizen stays out of the country for more than 182 days, he becomes non-resident,” said Revenue Secy Ajay Bhushan Pandey. “Now in order to become non-resident, he has to stay out of the country for 240 days.”

The second rule is more deadly: a non-resident Indian, who is not taxed in the foreign country, will become taxable in India.

“If any Indian citizen is not a resident of any country in the world, he'll be deemed to be a resident of India and his worldwide income will be taxed,” said Pandey.

"It's a very big disadvantage for Indians residing overseas only to save on tax,"  said Dinesh Kanabar of Dhruva Advisors. He expects that many Indians stay abroad in countries, where the income tax is low or nil such as Dubai. Now they will be taxed in India if they are in the income tax bracket.

For Indians, finance minister Nirmala Sitharaman revised income tax rats and proposed new tax slabs.

The new income tax rates will, however, not allow exemptions under Section 80C. Home loan exemption, insurance exemptions, the standard deduction will also not stay under the regime.

"The new tax regime will be optional and the taxpayers will be given the choice to either remain in the old regime with exemptions and deductions or opt for the new reduced tax rate without those exemptions," Sitharaman said while unveiling Budget.

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.
