After Modi biopic, Vivek Oberoi gearing up to contest from Gujarat in 2024 polls

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.

New Delhi, Jun 14: Petrol price on Sunday was hiked by a record 62 paise per litre and that of diesel by 64 paise as oil companies for the eighth day in a row adjusted retail rates in line with cost since ending an 82-day hiatus in rate revision.

Petrol price in Delhi was hiked to Rs 75.78 per litre from Rs 75.16 while diesel rates were increased to Rs 74.03 a litre from Rs 73.39, according to a price notification of state oil marketing companies.

Rates have been increased across the country and vary from state to state depending on the incidence of local sales tax or VAT.

The 62 paise a litre increase in petrol and 64 paise hike in diesel price is the highest surge in rates since the daily price revision was started in June 2017.

This is the eighth daily increase in rates in a row since oil companies on June 7 restarted revising prices in line with costs, after ending an 82-day hiatus.

In eight hikes, petrol price has gone up by Rs 4.52 per litre and diesel by Rs 4.64 -- a record increase in rates in any eight days since the daily price revision was introduced.

The freeze in rates was imposed in mid-March soon after the government hiked excise duty on petrol and diesel to shore up additional finances.

Oil PSUs Indian Oil Corp (IOC), Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corp Ltd (HPCL), instead of passing on the excise duty hikes to customers, adjusted them against the fall in the retail rates that was warranted because of international oil prices falling to two-decade lows.

The government had first raised excise duty on petrol and diesel by Rs 3 per litre each on March 14 and then again on May 5 by a record Rs 10 per litre in case of petrol and Rs 13 on diesel. The two hikes gave the government Rs 2 lakh crore in additional tax revenues.

State-owned fuel retailers IOC, BPCL and HPCL had frozen petrol and diesel prices since March 16, as if anticipating the government move and set off gains they accrued from continuing drop in international oil prices against the excise duty hike.

They, however, promptly passed the increase in local sales tax or VAT by state governments such as Rs 1.67 increase in VAT on petrol and Rs 7.10 in diesel by the Delhi government on May 4.

The total incidence of excise duty on petrol has risen to Rs 32.98 per litre and that on diesel to Rs 31.83. The excise tax on petrol was Rs 9.48 per litre when the Narendra Modi government took office in 2014 and that on diesel was Rs 3.56 a litre.

The government had between November 2014 and January 2016 raised excise duty on petrol and diesel on nine occasions to take away gains arising from plummeting global oil prices.

In all, duty on petrol rate was hiked by Rs 11.77 per litre and that on diesel by 13.47 a litre in those 15 months that helped government's excise mop up more than double to Rs 2,42,000 crore in 2016-17 from Rs 99,000 crore in 2014-15.

It cut excise duty by Rs 2 in October 2017 and by Rs 1.50 a year later. But it raised excise duty by Rs 2 per litre in July 2019.

It again raised excise duty on March 14 by Rs 3 per litre.

London, Feb 12: Oscar-winning British director Steve McQueen is returning to his art roots with a series of short films at London's Tate Modern art gallery, offering a sensory exploration of black identity.

McQueen, who became the first black director to win the best picture Academy Award in 2014 for "12 Years a Slave", is now based between London and Amsterdam and is focused on championing diversity in the film industry.

Visitors to his new exhibition will be greeted by "Static", a film of New York's Statue of Liberty, scrutinising the iconic symbol from every possible angle at very close range against a deafening backdrop of the helicopter from where the footage was filmed.

"What interests Steve is our view of the world, how humans are trying to represent Liberty," said Fiontan Moran, assistant curator of the exhibition.

"7th Nov, 2001" features a still shot of a body while McQueen's cousin Marcus tells of how he accidentally killed his brother, a particularly traumatic experience for the artist.

"Western Deep" is another visceral work, giving a sense through sights and sounds in an interactive installation of the experiences of miners in South Africa, following them to the bottom of the mine.

"Ashes", meanwhile, is a tribute to a young fisherman from Grenada, the island where McQueen's family originated.

The images of beauty and sweetness filmed from his boat are tragically reversed on the other side of the projection screen, which shows a grave commissioned by McQueen for the eponymous young fisherman, who was killed by drug traffickers.

African-American singer, actor and civil rights activist Paul Robeson (1898-1976) is honoured in "End Credits".

The film shows censored FBI documents detailing the agency's surveillance of Robeson, read by a voice-over artist, for five hours.

"He is... testing the limits of how people can be documented in an era of mass surveillance," said Moran.

In a similarly militant vein, the exhibition features the sculpture "Weight", which was first shown in the prison cell where the writer and playwright Oscar Wilde was imprisoned.

It depicts a golden mosquito net draped over a metal prison bed frame, addressing the theme of confinement and the power of the imagination to break free.

The show runs alongside an exhibition of McQueen's giant portraits of London school classes, many of which appeared on the streets of London last year.

"I remember my first school trip to Tate when I was an impressionable eight-year-old, which was really the moment I gained an understanding that anything is possible," said McQueen, adding it was "where in some ways my journey as an artist first began".

He recently told the Financial Times newspaper the difference between his art films and his feature films was that the former were poetry, the latter like a novel.

"Poetry is condensed, precise, fragmented," he said. "The novel is the yarn".

The exhibition opens on February 13 and runs until May 11.
