Stockholm, Oct 8: The Nobel Prize in Physics was on Tuesday awarded with one half to James Peebles for his theoretical discoveries in physical cosmology and the other half jointly to Michel Mayor and Didier Queloz for discovering an exoplanet orbiting a solar-type star.

The prize was announced by Secretary-General of the Royal Swedish Academy of Sciences, Goran K Hansson.

"The 2019 Nobel Prize in Physics has been awarded one half to James Peebles for theoretical discoveries in physical cosmology and the other half jointly to Michel Mayor and Didier Queloz for the discovery of an exoplanet orbiting a solar-type star," the official Twitter handle of The Nobel Prize tweeted.

Nobel Prize is a set of annual international awards bestowed for outstanding work in fields of physics, chemistry, physiology or medicine, literature, economics, and the promotion of peace.

The discovery by laureates Michel Mayor and Didier Queloz started a revolution in astronomy and over 4,000 exoplanets have since been found in the Milky Way, a statement read.

"Strange new worlds are still being discovered, with an incredible wealth of sizes, forms and orbits," it read. This year's Physics Laureates Michel Mayor and Didier Queloz have explored our home galaxy, the Milky Way, looking for unknown worlds.

In 1995, they made the first discovery of a planet outside our solar system, an exoplanet, orbiting a solar-type star, 51 Pegasi.

Another Nobel Prize winner -- James Peebles took on the cosmos, with its billions of galaxies and galaxy clusters.

"His theoretical framework, developed over two decades, is the foundation of our modern understanding of the universe's history, from the Big Bang to the present day," it said.

This year's Nobel Prize in Physics rewards new understanding of the universe's structure and history, and the first discovery of a planet orbiting a solar-type star outside our solar system. The discoveries have forever changed our conceptions of the world.

On Monday, the Nobel Prize in Physiology or Medicine was jointly awarded to William G Kaelin Jr, Peter J Ratcliffe and Gregg L Semenza for their discoveries of how cells sense and adapt to oxygen availability.

Beijing, Jan 23: China is putting on lockdown a city of 11 million people considered the epicenter of the new coronavirus outbreak that has killed 17 and infected nearly 600 people, as health authorities around the world work to prevent a global pandemic.

The previously unknown coronavirus strain is believed to have emerged late last year from illegally traded wildlife at an animal market in the central Chinese city of Wuhan. Cases have been detected as far away as the United States, stoking fears the virus is already spreading worldwide.

Wuhan's local government said it would shut down all urban transport networks and suspend outgoing flights from the city as of 10 a.m. (0200 GMT) Thursday, state media reported, adding that the government is urging citizens to not leave the city in the absence of special circumstances.

Contrasting with its secrecy over the 2002-03 Severe Acute Respiratory Syndrome (SARS), which killed nearly 800 people, China's communist government has this time given regular updates to try to avoid panic as millions of people travel for the Chinese Lunar New Year holiday.

Chinese authorities have confirmed 571 cases and 17 deaths as of end-Wednesday, state television reported on Thursday. There are eight other known cases around the world - Thailand has confirmed four cases, while the United States, Taiwan, South Korea and Japan have each reported one.

Vice Premier Sun Chunlan said during a visit to Wuhan that authorities needed to be open about the spread of the virus and their efforts to contain it, the official Xinhua news agency reported on Thursday, comments likely to reassure global health experts.

After a meeting at its Geneva headquarters on Wednesday, the World Health Organization (WHO) said it would decide on Thursday whether to declare the outbreak a global health emergency, which would step up the international response.

If it does so, it will be the sixth international public health emergency to be declared in the last decade.

WHO Director-General Tedros Adhanom Ghebreyesus told reporters in Geneva that China's actions so far were "very strong" but called in Beijing to take "more and significant measures to limit or minimise the international spread".

"We stressed to them that by having a strong action not only they will control the outbreak in their country but they will also minimise the chances of this outbreak spreading internationally. So they recognise that," he said.

A senior U.S. State Department official also called on China to "play a bigger role in global health so they taking more and significant measures to limit or minimise the international spread".

"The lack of transparency in the past, especially with SARS ... gives us concern that that may be the case here," the official said, adding however that there were "positive signs that they have taken action in Wuhan".

Fears of a pandemic initially spooked markets but they regained their footing on Wednesday, with investors citing the robust response from authorities as reassuring.

VIRUS SPREADING

The outbreak began in Wuhan, a major transportation hub as well as central China's main industrial and commercial centre, and has now spread to other major population centers including Beijing, Shanghai and Hong Kong.

There is no known cure for the virus. Symptoms include fever, difficulty in breathing and cough, similar to many other respiratory illnesses, and can cause pneumonia.

Chinese authorities are still investigating the origins of the virus, though they confirmed the outbreak began at a market in Wuhan with illegal wildlife transactions and that it can spread from one person to another via respiratory transmission. Among confirmed patients are 15 medical workers, further adding to worries about a possible global pandemic.

Many Chinese were canceling trips, buying face masks, avoiding public places such as cinemas and shopping centers, and even turning to an online plague simulation game as a way to cope.

Airports globally stepped up screening passengers from China and the European Centre for Disease Control and Prevention (ECDC) said in a risk assessment that further global spread of the virus was likely.

Britain joined other countries including Australia in advising citizens against all but essential travel to Wuhan.

Feb 26: China’s massive travel restrictions, house-to-house checks, huge isolation wards and lockdowns of entire cities bought the world valuable time to prepare for the global spread of the new virus.

But with troubling outbreaks now emerging in Italy, South Korea and Iran, and U.S. health officials warning Tuesday it’s inevitable it will spread more widely in America, the question is: Did the world use that time wisely and is it ready for a potential pandemic?

“It’s not so much a question of if this will happen anymore, but rather more a question of exactly when this will happen — and how many people in this country will have severe illness,” said Dr. Nancy Messonnier of the U.S. Centers for Disease Control and Prevention.

Some countries are putting price caps on face masks to combat price gouging, while others are using loudspeakers on trucks to keep residents informed. In the United States and many other nations, public health officials are turning to guidelines written for pandemic flu and discussing the possibility of school closures, telecommuting and canceling events.

Countries could be doing even more: training hundreds of workers to trace the virus’ spread from person to person and planning to commandeer entire hospital wards or even entire hospitals, said Dr. Bruce Aylward, the World Health Organization’s envoy to China, briefing reporters Tuesday about lessons learned by the recently returned team of international scientists he led.

“Time is everything in this disease,” Aylward said. “Days make a difference with a disease like this.”

The U.S. National Institutes of Health’s infectious disease chief, Dr. Anthony Fauci, said the world is “teetering very, very close” to a pandemic. He credits China’s response for giving other nations some breathing room.

China locked down tens of millions of its citizens and other nations imposed travel restrictions, reducing the number of people who needed health checks or quarantines outside the Asian country.

It “gave us time to really brush off our pandemic preparedness plans and get ready for the kinds of things we have to do,” Fauci said. “And we’ve actually been quite successful because the travel-related cases, we’ve been able to identify, to isolate” and to track down those they came in contact with.

With no vaccine or medicine available yet, preparations are focused on what’s called “social distancing” — limiting opportunities for people to gather and spread the virus.

That played out in Italy this week. With cases climbing, authorities cut short the popular Venice Carnival and closed down Milan’s La Scala opera house. In Japan, Prime Minister Shinzo Abe called on companies to allow employees to work from home, while the Tokyo Marathon has been restricted to elite runners and other public events have been canceled.

Is the rest of the world ready?

In Africa, three-quarters of countries have a flu pandemic plan, but most are outdated, according to authors of a modeling study published last week in The Lancet medical journal. The slightly better news is that the African nations most connected to China by air travel — Egypt, Algeria and South Africa — also have the most prepared health systems on the continent.

Elsewhere, Thailand said it would establish special clinics to examine people with flu-like symptoms to detect infections early. Sri Lanka and Laos imposed price ceilings for face masks, while India restricted the export of personal protective equipment.

India’s health ministry has been framing step-by-step instructions to deal with sustained transmissions that will be circulated to the 250,000 village councils that are the most basic unit of the country’s sprawling administration.

Vietnam is using music videos on social media to reach the public. In Malaysia, loudspeakers on trucks blare information through the streets.

In Europe, portable pods set up at United Kingdom hospitals will be used to assess people suspected of infection while keeping them apart from others. France developed a quick test for the virus and has shared it with poorer nations. German authorities are stressing “sneezing etiquette” and Russia is screening people at airports, railway stations and those riding public transportation.

In the U.S., hospitals and emergency workers for years have practiced for a possible deadly, fast-spreading flu. Those drills helped the first hospitals to treat U.S. patients suffering from COVID-19, the disease caused by the virus.

Other hospitals are paying attention. The CDC has been talking to the American Hospital Association, which in turn communicates coronavirus news daily to its nearly 5,000 member hospitals. Hospitals are reviewing infection control measures, considering using telemedicine to keep potentially infectious patients from making unnecessary trips to the hospital and conserving dwindling supplies of masks and gloves.

What’s more, the CDC has held 17 different calls reaching more than 11,000 companies and organizations, including stadiums, universities, faith leaders, retailers and large corporations. U.S. health authorities are talking to city, county and state health departments about being ready to cancel mass gathering events, close schools and take other steps.

The CDC’s Messonnier said Tuesday she had contacted her children’s school district to ask about plans for using internet-based education should schools need to close temporarily, as some did in 2009 during an outbreak of H1N1 flu. She encouraged American parents to do the same, and to ask their employers whether they’ll be able to work from home.

“We want to make sure the American public is prepared,” Messonnier said.

How prepared are U.S. hospitals?

“It depends on caseload and location. I would suspect most hospitals are prepared to handle one to two cases, but if there is ongoing local transmission with many cases, most are likely not prepared just yet for a surge of patients and the ‘worried well,’” Dr. Jennifer Lighter, a pediatric infectious diseases specialist at NYU Langone in New York, said in an email.

In the U.S., a vaccine candidate is inching closer to first-step safety studies in people, as Moderna Inc. has delivered test doses to Fauci’s NIH institute. Some other companies say they have candidates that could begin testing in a few months. Still, even if those first safety studies show no red flags, specialists believe it would take at least a year to have something ready for widespread use. That’s longer than it took in 2009, during the H1N1 flu pandemic — because that time around, scientists only had to adjust regular flu vaccines, not start from scratch.

The head of the World Health Organization, Tedros Adhanom Ghebreyesus, said the U.N. health agency’s team in China found the fatality rate between 2% and 4% in the hard-hit city of Wuhan, the virus’ epicenter, and 0.7% elsewhere.

The world is “simply not ready,” said the WHO’s Aylward. “It can get ready very fast, but the big shift has to be in the mindset.”

Aylward advised other countries to do “really practical things” now to get ready.

Among them: Do you have hundreds of workers lined up and trained to trace the contacts of infected patients, or will you be training them after a cluster pops up?

Can you take over entire hospital wards, or even entire hospitals, to isolate patients?

Are hospitals buying ventilators and checking oxygen supplies?

Countries must improve testing capacity — and instructions so health workers know which travelers should be tested as the number of affected countries rises, said Johns Hopkins University emergency response specialist Lauren Sauer. She pointed to how Canada diagnosed the first traveler from Iran arriving there with COVID-19, before many other countries even considered adding Iran to the at-risk list.

If the disease does spread globally, everyone is likely to feel it, said Nancy Foster, a vice president of the American Hospital Association. Even those who aren’t ill may need to help friends and family in isolation or have their own health appointments delayed.

“There will be a lot of people affected even if they never become ill themselves,” she said.

New Delhi, May 27: India’s fourth recession since Independence, first since liberalisation, and perhaps the worst to date is here, according to rating agency, Crisil.

CRISIL sees the Indian economy shrinking 5 per cent in fiscal 2021 (on-year), because of the Covid-19 pandemic. The first quarter will suffer a staggering 25 per cent contraction.

About 10 per cent of gross domestic product (GDP) in real terms could be permanently lost. "So going back to the growth rates seen before the pandemic is unlikely in the next three fiscals", Crisil said.

Crisil has revised its earlier forecast downwards. "Earlier, on April 28, we had slashed our prediction to 1.8 per cent growth from 3.5 per cent growth. Things have only gone downhill since", it said.

While we expect non-agricultural GDP to contract 6 per cent, agriculture could cushion the blow by growing at 2.5 per cent.

In the past 69 years, India has seen a recession only thrice as per available data in fiscals 1958, 1966 and 1980. The reason was the same each time a monsoon shock that hit agriculture, then a sizeable part of the economy.

"The recession staring at us today is different," it added. For one, agriculture could soften the blow this time by growing near its trend rate, assuming a normal monsoon. Two, the pandemic-induced lockdowns have affected most non-agriculture sectors. And three, the global disruption has upended whatever opportunities India had on the exports front.

Economic conditions have slid precipitously since the April-end forecast of 1.8 per cent GDP growth for fiscal 2021 (baseline), Crisil said.

On the lockdown extension, it said that the government has extended the lockdown four times to deal with the rising number of cases, curtailing economic activity severely (lockdown 4.0 is ending on May 31).

The first quarter of this fiscal will be the worst affected. June is unlikely to see major relaxations as the Covid-19 affliction curve is yet to flatten in India.

"Not only will the first quarter be a washout for the non-agricultural economy, services such as education, and travel and tourism among others, could continue to see a big hit in the quarters to come. Jobs and incomes will see extended losses as these sectors are large employers," Crisil said.

CRISIL also foresees economic activity in states with high Covid-19 cases to suffer prolonged disruption as restrictions could continue longer.

A rough estimate based on a sample of eight states, which contribute over half of India's GDP, shows that their 'red zones' (as per lockdown 3.0) contributed 42 per cent to the state GDP on average regardless of the share of such red zones.

On average, the orange zones contribute 46 per cent, while the green zones where activity is allowed to be close to normal contribute only 12 per cent to state GDP.

The economic costs are higher than earlier expectations, according to Crisil. The economic costs now beginning to show up in the hard numbers are far worse than initial expectations.

Industrial production for March fell by over 16%. The purchasing managers indices for the manufacturing and services sectors were at 27.4 and 5.4, respectively, in April, implying extraordinary contraction. That compares with 51.8 and 49.3, respectively, in March.

Exports contracted 60.3 per cent in April, and new telecom subscribers declined 35 per cent, while railway freight movement plunged 35 per cent on-year.

"Indeed, given one of the most stringent lockdowns in the world, April could well be the worst performing month for India this fiscal," it said.

Added to that is the economic package without enough muscle. The government recently announced a Rs 20.9 lakh crore economic relief package to support the economy. The package has some short-term measures to cushion the economy, but sets its sights majorly on reforms, most of which will have payoffs only over the medium term.

"We estimate the fiscal cost of this package at 1.2 per cent of GDP, which is lower than what we had assumed in our earlier estimate (when we foresaw a growth in GDP)," it said.

"We believe a catch-up to the pre-crisis trend level of GDP growth will not be possible in the next three fiscals despite policy support. Under the base case, we estimate a 10 per cent permanent loss to real GDP (from the decadal-trend level), assuming average growth of about 7 per cent between fiscals 2022 and 2024," Crisil said.

Interestingly, after the Global Financial Crisis (GFC), a sharp growth spurt helped catch up with the trend within two years. GDP grew 8.2 per cent on average in the two fiscals following the GFC. Massive fiscal spending, monetary easing and swift global recovery played a role in a V-shaped recovery.

To catch-up would require average GDP growth to surge to 11 per cent over the next three fiscals, something that has never happened before.

The research said that successive lockdowns have a non-linear and multiplicative effect on the economy a two-month lockdown will be more than twice as debilitating as a one-month imposition, as buffers keep eroding.

Partial relaxations continue to be a hindrance to supply chains, transportation and logistics. Hence, unless the entire supply chain is unlocked, the impact of improved economic activity will be subdued.

Therefore, despite the stringency of lockdown easing a tad in the third and the fourth phases, their negative impact on GDP is expected to massively outweigh the benefits from mild fiscal support and low crude oil prices, especially in the April-June quarter. "Consequently, we expect the current quarter's GDP to shrink 25 per cent on-year," it said.

Counting lockdown 4.0, Indians have had 68 days of confinement. S&P Global estimates that one month of lockdown shaves 3 per cent off annual GDP on average across Asia-Pacific.

Since India's lockdown has been the most stringent in Asia, the impact on economic growth will be correspondingly larger.

Google's Community Mobility Reports show a sharp fall in movement of people to places of recreation, retail shops, public transport and workplace travel. While data for May shows some improvement in India, mobility trends are much below the average or baseline, and lower compared with countries such as the US, South Korea, Brazil and Indonesia.
