New Delhi, Jun 25: Union Home Minister Amit Shah on Thursday hit out at Congress for "unceremoniously sacking" its spokesperson and said that leaders in the opposition party are "feeling suffocated".

To substantiate his point, Shah referred to the recent Congress Working Committee (CWC) meet in which senior members and younger members raised a few issues, however, they were "shut down".

Taking to Twitter, Shah posted two English dailies' articles titled -- "Not scared of PM Modi, but many in the party dodge him: Rahul at Congress Working Committee meet" and "Congress removes Sanjay Jha as party spokesperson after critical article".

Last week, Jha was dropped as AICC spokesperson and Abhishek Dutt and Sadhna Bharti appointed as National Media Panelist of Congress party.

"During the recent CWC meet, senior members and younger members raised a few issues. But, they were shouted down. A party spokesperson was unceremoniously sacked. The sad truth is - leaders are feeling suffocated in Congress," the Union Minister tweeted.

Meanwhile, Shah also targetted Congress on the completion of 45 years of emergency, which was imposed by former Prime Minister Indira Gandhi on June 25, 1975 and asked the party to self introspect.

"As one of India's opposition parties, Congress needs to ask itself: Why does the Emergency mindset remain? Why are leaders who do not belong to 1 dynasty unable to speak up? Why are leaders getting frustrated in Congress? Else, their disconnect with people will keep widening," he wrote.

Chennai, Feb 20: Three people, including an assistant director were killed and 9 others injured when a crane used for the shooting of “actor Kamal Haasan starrer “Indian 2” film crashed down at Nazarathpet near Poonamallee here late on Wednesday night.

Police said the accident occurred when a group of workers were engaged in erecting a set for a scene at EVP film city, private studio. As the crane crashed down, a heavy-duty light stand that was mounted on it also fell on the workers.

Mr Haasan and the film director S.Shankar escaped unhurt in the accident.

The deceased were identified as Krishna (34), an assistant director of the film, Madhu (29) and Chandran (60), who was part of the catering team.

Tamil Nadu Fire and Rescue Services personnel, along with a fire tender from Irungattukottai rushed to the spot and retrieved the bodies from the spot.

Mr Haasan, who was at the accident spot, also helped to transport the injured people to a private hospital near Poonamallee.

The bodies were sent to the Government General Hospital for post-mortem.

The Nazarathpet police have filed a case and are investigating the cause of the accident.

Meanwhile, Mr.Haasan condoled the death of three people during the film shoot. “The accident is the most horrific I have seen in my film career. I have lost three colleagues, but my pain pales in comparison to the grief of those who have lost their loved ones.

My deepest sympathies to them, he tweeted.

The Lyca productions also expressed condolences over the tragic accident. “We are extremely saddened with the unfortunate accident happened at the sets of Indian 2. We have lost three of our most hardworking technicians, it tweeted.

New Delhi, Jun 15: Average temperature of India experienced a rise of 0.7 degree Celsius, along with decline in rainfall, significant increase in frequency of very severe cyclonic storms and droughts in over a decade due to human activities, the Ministry of Earth Sciences in its research report said.

The contentions were made in a report issued by the ministry on the impact of climate change. It will be published by Union Minister Harsh Vardhan on June 19.

According to the report, "Since the middle of the twentieth century, India witnessed rise in temperature; decrease in monsoon; rise in extreme temperature and rainfall, droughts, and sea levels; and increase intensity of severe cyclones.

The report, prepared by researchers of the Centre for Climate Change Research, a cell under The Ministry's Indian Institute of Tropical Meteorology, Pune, further stated that there is compelling scientific evidence that human activities have influenced these changes in regional climate.

India's average temperature has risen by around 0.7 degrees Celsius during 1901-2018, it said, adding that the rise is largely on account of GHG-induced warming and partially offset by forcing due to anthropogenic aerosols.

It states that the average temperature over India is projected to rise by 4.4 degrees Celsius, while the intensity of heat waves is likely to increase by 3-4 times by the end of the century.

In the 30-year period between 1986 and 2015, temperatures of the warmest day and the coldest night of the year have risen by about 0.63 degrees Celsius and 0.4 degree Celsius.

According to the report, by the end of the century, the temperatures of the warmest day and the coldest night are projected to rise by approximately 4.7 degrees Celsius and 5.5 degrees Celsius, respectively.

Alarmingly, sea surface temperature of the tropical Indian Ocean has also risen by one degrees Celsius on average during 1951-2015.

"The frequency of very severe cyclonic storms during the post-monsoon season has increased significantly (+1 event per decade) during the last two decades (2000-2018)," it added.

This came in the backdrop of Cyclone 'Amphan' and 'Nisarga' which made landfalls on May 20 and June 3 and killed several people, flattened villages, and destroyed farms.

"This is the first-ever climate change assessment report for India. This report will be very useful for policy makers, researchers, social scientists, economists, and students," said M. Rajeevan, secretary, the Ministry of Earth Sciences.

Besides this, the report also highlighted various other unnerving data on climate change in the country. Both the frequency and extent of droughts have increased significantly during 1951-2016.

The overall decrease of seasonal "summer monsoon rainfall" during the last 6-7 decades has led to an increased propensity for droughts over India.

"In particular, areas over central India, southwest coast, southern peninsula and north-eastern India have experienced more than 2 droughts per decade, on average, during this period. The area affected by drought has also increased by 1.3 per cent per decade over the same period."

The Hindu Kush Himalayas (HKH) also experienced a temperature rise of about 1.3 degree Celsius during 1951-2014.

Several areas of the Himalayas have experienced a declining trend in snowfall and also retreat of glaciers in recent decades. By the end of the twenty-first century, its annual mean surface temperature is projected to increase by about 5.2 degree Celsius.

The summer monsoon precipitation from June to September over India has also declined by around 6 per cent from 1951 to 2015, with notable decreases over the Indo-Gangetic Plains and the Western Ghats, the report further states.

When researcher Monica Gandhi began digging deeper into outbreaks of the novel coronavirus, she was struck by the extraordinarily high number of infected people who had no symptoms.

A Boston homeless shelter had 147 infected residents, but 88% had no symptoms even though they shared their living space. A Tyson Foods poultry plant in Springdale, Ark., had 481 infections, and 95% were asymptomatic.

Prisons in Arkansas, North Carolina, Ohio and Virginia counted 3,277 infected people, but 96% were asymptomatic.

During its seven-month global rampage, the coronavirus has claimed more than 700,000 lives. But Gandhi began to think the bigger mystery might be why it has left so many more practically unscathed.

What was it about these asymptomatic people, who lived or worked so closely to others who fell severely ill, she wondered, that protected them? Did the "dose" of their viral exposure make a difference? Was it genetics? Or might some people already have partial resistance to the virus, contrary to our initial understanding?

Efforts to understand the diversity in the illness are finally beginning to yield results, raising hope that the knowledge will help accelerate development of vaccines and therapies - or possibly even create new pathways toward herd immunity in which enough of the population develops a mild version of the virus that they block further spread and the pandemic ends.

"A high rate of asymptomatic infection is a good thing," said Gandhi, an infectious-disease specialist at the University of California at San Francisco. "It's a good thing for the individual and a good thing for society."

The coronavirus has left numerous clues - the uneven transmission in different parts of the world, the mostly mild impact on children. Perhaps most tantalizing is the unusually large proportion of infected people with mild symptoms or none at all. The Centers for Disease Control and Prevention last month estimated that rate at about 40%.

Those clues have sent scientists off in different directions: Some are looking into the role of the receptor cells, which the virus uses to infiltrate the body, to better understand the role that age and genetics might play. Others are delving into masks and whether they may filter just enough of the virus so those wearing them had mild cases or no symptoms at all.

The theory that has generated the most excitement in recent weeks is that some people walking among us might already have partial immunity.

When SARS-CoV-2, the technical name of the coronavirus that causes the disease covid-19, was first identified on Dec. 31, 2019, public health officials deemed it a "novel" virus because it was the first time it had been seen in humans who presumably had no immunity from it whatsoever. There's now some very early, tentative evidence suggesting that assumption might have been wrong.

One mind-blowing hypothesis - bolstered by a flurry of recent studies - is that a segment of the world's population may have partial protection thanks to "memory" T cells, the part of our immune system trained to recognize specific invaders. 

This could originate from cross-protection derived from standard childhood vaccinations. Or, as a paper published Tuesday in Science suggested, it could trace back to previous encounters with other coronaviruses, such as those that cause the common cold.

"This might potentially explain why some people seem to fend off the virus and may be less susceptible to becoming severely ill," National Institutes of Health Director Francis Collins remarked in a blog post this past week.

On a population level, such findings, if validated, could be far-reaching.

Hans-Gustaf Ljunggren, a researcher at Sweden's Karolinska Institute, and others have suggested that public immunity to the coronavirus could be significantly higher than what has been suggested by studies. In communities in Barcelona, Boston, Wuhan and other major cities, the proportion of people estimated to have antibodies and therefore presumably be immune has mostly been in the single digits. But if others had partial protection from T cells, that would raise a community's immunity level much higher.

This, Ljunggren said, would be "very good news from a public health perspective."

Some experts have gone so far as to speculate about whether some surprising recent trends in the epidemiology of the coronavirus - the drop in infection rates in Sweden where there have been no widespread lockdowns or mask requirements, or the high rates of infection in Mumbai's poor areas but little serious disease - might be due to preexisting immunity.

Others say it's far too early to draw such conclusions. Anthony Fauci, the United States' top infectious-disease expert, said in an interview that while these ideas are being intensely studied, such theories are premature. He said at least some partial preexisting immunity in some individuals seems a possibility.

And he said the amount of virus someone is exposed to - called the inoculum - "is almost certainly an important and likely factor" based on what we know about other viruses.

But Fauci cautioned that there are multiple likely reasons - including youth and general health - that determine whether a particular individual shrugs off the disease or dies of it. That reinforces the need, in his view, for continued vigilance in social distancing, masking and other precautions.

"There are so many other unknown factors that maybe determine why someone gets an asymptomatic infection," Fauci said. "It's a very difficult problem to pinpoint one thing."

News headlines have touted the idea based on blood tests that 20% of some New York communities might be immune, 7.3% in Stockholm, 7.1% in Barcelona. Those numbers come from looking at antibodies in people's blood that typically develop after they are exposed to a virus. But scientists believe another part of our immune system - T cells, a type of white blood cell that orchestrates the entire immune system - could be even more important in fighting against the coronavirus.

Recent studies have suggested that antibodies from the coronavirus seem to stick around for two to three months in some people. While work on T cells and the coronavirus is only getting started - testing T cells is much more laborious than antibody testing - previous research has shown that, in general, T cells tend to last years longer.

One of the first peer-reviewed studies on the coronavirus and T cells was published in mid-May in the journal Cell by Alessandro Sette, Shane Crotty and others at the La Jolla Institute for Immunology near San Diego.

The group was researching blood from people who were recovering from coronavirus infections and wanted to compare that to samples from uninfected controls who were donors to a blood bank from 2015 to 2018. The researchers were floored to find that in 40% to 60% of the old samples, the T cells seemed to recognize SARS-CoV-2.

"The virus didn't even exist back then, so to have this immune response was remarkable," Sette said.

Research teams from five other locations reported similar findings. In a study from the Netherlands, T cells reacted to the virus in 20% of the samples. In Germany, 34%. In Singapore, 50%.

The different teams hypothesized this could be due to previous exposure to similar pathogens. Perhaps fortuitously, SARS-CoV-2 is part of a large family of viruses. Two of them - SARS and MERS - are deadly and led to relatively brief and contained outbreaks. Four other coronavirus variants, which cause the common cold, circulate widely each year but typically result in only mild symptoms. Sette calls them the "less-evil cousins of SARS-CoV-2."

This week, Sette and others from the team reported new research in Science providing evidence the T cell responses may derive in part from memory of "common cold" coronaviruses.

"The immune system is basically a memory machine," he said. "It remembers and fights back stronger."

The researchers noted in their paper that the strongest reaction they saw was against the spike proteins that the virus uses to gain access to cells - suggesting that fewer viral copies get past these defenses.

"The current model assumes you are either protected or you are not - that it's a yes or no thing," Sette added. "But if some people have some level of preexisting immunity, that may suggest it's not a switch but more continuous."

More than 2,300 miles away, at the Mayo Clinic in Cleveland, Andrew Badley was zeroing in the possible protective effects of vaccines.

Teaming up with data experts from Nference, a company that manages their clinical data, he and other scientists looked at records from 137,037 patients treated at the health system to look for relationships between vaccinations and coronavirus infection.

They knew that the vaccine for smallpox, for example, had been shown to protect against measles and whooping cough. Today, a number of existing vaccines are being studied to see whether any might offer cross-protection against SARS-CoV-2.

When SARS-CoV-2, the technical name of the coronavirus that causes the disease covid-19, was first identified on Dec. 31, 2019

The results were intriguing: Seven types of vaccines given one, two or five years in the past were associated with having a lower rate of infection with the new coronavirus. Two vaccines in particular seemed to show stronger links: People who got a pneumonia vaccine in the recent past appeared to have a 28% reduction in coronavirus risk. Those who got polio vaccines had a 43% reduction in risk.

Venky Soundararajan, chief scientific officer of Nference, remembers when he first saw how large the reduction appeared to be, he immediately picked up his phone and called Badley: "I said, 'Is this even possible?'"

The team looked at dozens of other possible explanations for the difference. It adjusted for geographic incidence of the coronavirus, demographics, comorbidities, even whether people had had mammograms or colonoscopies, under the assumption that people who got preventive care might be more apt to social distance. But the risk reduction still remained large.

"This surprised us completely," Soundararajan recalled. "Going in we didn't expect anything or maybe one or two vaccines showing modest levels of protection."

The study is only observational and cannot show a causal link by design, but Mayo researchers are looking at a way to quantify the activity of these vaccines on the coronavirus to serve as a benchmark to the new vaccines being created by companies such as Moderna. If existing vaccines appear as protective as new ones under development, he said, they could change the world's whole vaccine strategy.

Meanwhile, at NIH headquarters in Bethesda, Md., Alkis Togias has been laser-focused on one group of the mildly affected: children. He wondered whether it might have something to do with the receptor known as ACE2, through which the virus hitchhikes into the body.

In healthy people, the ACE2 receptors perform the important function of keeping blood pressure stable. The novel coronavirus latches itself to ACE2, where it replicates. Pharmaceutical companies are trying to figure out how to minimize the receptors or to trick the virus into attaching itself to a drug so it does not replicate and travel throughout the body.

Was it possible, Togias asked, that children naturally expressed the receptor in a way that makes them less vulnerable to infection?

He said recent papers have produced counterintuitive findings about one subgroup of children - those with a lot of allergies and asthma. The ACE2 receptors in those children were diminished, and when they were exposed to an allergen such as cat hair, the receptors were further reduced. Those findings, combined with data from hospitals showing that asthma did not seem to be a risk factor for the respiratory virus, as expected, have intrigued researchers.

"We are thinking allergic reactions may protect you by down-regulating the receptor," he said. "It's only a theory of course."

Togias, who is in charge of airway biology for the National Institute of Allergy and Infectious Diseases, is looking at how those receptors seem to be expressed differently as people age, as part of a study of 2,000 U.S. families. By comparing those differences and immune responses within families, they hope to be able to better understand the receptors' role.

Separately, a number of genetic studies show variations in genes associated with ACE2 with people from certain geographic areas, such as Italy and parts of Asia, having distinct mutations. No one knows what significance, if any, these differences have on infection, but it's an active area of discussion in the scientific community.

Before the pandemic, Gandhi, the University of California researcher, specialized in HIV. But like other infectious-disease experts these days, she has spent many of her waking hours thinking about the coronavirus. And in scrutinizing the data on outbreaks one day, she noticed what might be a pattern: People were wearing masks in the settings with the highest percentage of asymptomatic cases.

The numbers on two cruise ships were especially striking. In the Diamond Princess, where masks weren't used and the virus was likely to have roamed free, 47% of those tested were asymptomatic. But in the Antarctic-bound Argentine cruise ship, where an outbreak hit in mid-March and surgical masks were given to all passengers and N95 masks to the crew, 81% were asymptomatic.

Similarly high rates of asymptomatic infection were documented at a pediatric dialysis unit in Indiana, a seafood plant in Oregon and a hair salon in Missouri, all of which used masks. Gandhi was also intrigued by countries such as Singapore, Vietnam and the Czech Republic that had population-level masking.

"They got cases," she noted, "but fewer deaths."

The scientific literature on viral dose goes back to around 1938 when scientists began to find evidence that being exposed to one copy of a virus is more easily overcome than being exposed to a billion copies. Researchers refer to the infectious dose as ID50 - or the dose at which 50% of the population would become infected.

While scientists do not know what that level might be for the coronavirus (it would be unethical to expose humans in this way), previous work on other nonlethal viruses showed that people tend to get less sick with lower doses and more sick with higher doses. A study published in late May involving hamsters, masks and SARS-CoV-2 found that those given coverings had milder cases than those who did not get them.

In an article published this month in the Journal of General Internal Medicine, Gandhi noted that in some outbreaks early in the pandemic in which most people did not wear masks, 15% of the infected were asymptomatic. But later on, when people began wearing masks, the rate of asymptomatic people was 40% to 45%.

She said the evidence points to masks not just protecting others - as U.S. health officials emphasize - but protecting the wearer as well. Gandhi makes the controversial argument that while people mostly have talked about asymptomatic infections as terrifying due to how people can spread the virus unwittingly, it could end up being a good thing.

"It is an intriguing hypothesis that asymptomatic infection triggering immunity may lead us to get more population-level immunity," Gandhi said. "That itself will limit spread."
