Was Rahul a UK citizen? EC postpones his nomination paper scrutiny to April 22

Jan 22: India's ranking in the latest global Democracy Index has dropped 10 places to the 51st spot out of 167 owing to violent protests and threats to civil liberties challenging freedoms across the country.

Prime Minister Narendra Modi's government has been criticized by rights groups and western governments after shutting off the internet and mobile phone networks and detaining opposition politicians in Kashmir.

Modi’s government has also responded harshly to ongoing protests against a controversial, religion-based citizenship law. Muslims have said their neighborhoods have been targeted, while the central government has attempted to ban protests and urged TV news channels not to broadcast “anti-national” content. Some leaders in Modi’s ruling party called for “revenge” against protesters. India’s score in 2019 was its worst ranking since the EIU’s records began in 2006, and has fallen gradually since Modi was elected in 2014.

The Economist Intelligence Unit’s 2019 Democracy Index, which provides an annual comparative analysis of political systems across 165 countries and two territories, said the past year was the bleakest for democracies since the research firm began compiling the list in 2006.

“The 2019 result is even worse than that recorded in 2010, in the wake of the global economic and financial crisis,” the research group said in releasing the report on Wednesday.

The average global score slipped to 5.44 out of a possible 10 -- from 5.48 in 2018 -- driven mainly by “sharp regressions” in Latin America, Sub-Saharan Africa, the Middle East and North Africa. Apart from coup-prone Thailand, which improved its score after holding an election last year, there were also notable declines in Asia after a tumultuous period of protests and new measures restricting freedom across the region’s democracies.

Asia Declines

Hong Kong, meanwhile, fell three places to rank 75th out of 167 as more than seven months of violent and disruptive protests rocked the Asian financial hub. An aggressive police response early in the unrest, when protests were mostly peaceful, led to a “marked decline in confidence in government -- the main factor behind the decline in the territory’s score in our 2019 index,” the group said.

In Singapore, which ranked alongside Hong Kong at 75th, a new “fake news” law led to a deteriorating score on civil liberties.

“The government claims that the law was enacted simply to prevent the dissemination of false news, but it threatens freedom of expression in Singapore, as it can be used to curtail political debate and silence critics of the government,” EIU analysts said.

China’s score fell to just 2.26 in the EIU’s ranking, placing it near the bottom of the list at 153, as discrimination against minorities, repression and surveillance of the population intensified. Still, in China “the majority of the population is unconvinced that democracy would benefit the economy, and support for democratic ideals is absent,” the EIU said.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

London/Milan, Jun 2: World Health Organization experts and a range of other scientists said on Monday there was no evidence to support an assertion by a high profile Italian doctor that the coronavirus causing the COVID-19 pandemic has been losing potency.

Professor Alberto Zangrillo, head of intensive care at Italy's San Raffaele Hospital in Lombardy, which bore the brunt of Italy's COVID-19 epidemic, on Sunday told state television that the new coronavirus "clinically no longer exists".

But WHO epidemiologist Maria Van Kerkhove, as well as several other experts on viruses and infectious diseases, said Zangrillo's comments were not supported by scientific evidence.

There is no data to show the new coronavirus is changing significantly, either in its form of transmission or in the severity of the disease it causes, they said.

"In terms of transmissibility, that has not changed, in terms of severity, that has not changed," Van Kerkhove told reporters.

It is not unusual for viruses to mutate and adapt as they spread, and the debate on Monday highlights how scientists are monitoring and tracking the new virus. The COVID-19 pandemic has so far killed more than 370,000 people and infected more than 6 million.

Martin Hibberd, a professor of emerging infectious disease at the London School of Hygiene & Tropical Medicine, said major studies looking at genetic changes in the SARS-CoV-2 virus that causes COVID-19 did not support the idea that it was becoming less potent, or weakening in any way.

"With data from more than 35,000 whole virus genomes, there is currently no evidence that there is any significant difference relating to severity," he said in an emailed comment.

Zangrillo, well known in Italy as the personal doctor of former Prime Minister Silvio Berlusconi, said his comments were backed up by a study conducted by a fellow scientist, Massimo Clementi, which Zangrillo said would be published next week.

Zangrillo told Reuters: "We have never said that the virus has changed, we said that the interaction between the virus and the host has definitely changed."

He said this could be due either to different characteristics of the virus, which he said they had not yet identified, or different characteristics in those infected.

The study by Clementi, who is director of the microbiology and virology laboratory of San Raffaele, compared virus samples from COVID-19 patients at the Milan-based hospital in March with samples from patients with the disease in May.

"The result was unambiguous: an extremely significant difference between the viral load of patients admitted in March compared to" those admitted last month, Zangrillo said.

Oscar MacLean, an expert at the University of Glasgow's Centre for Virus Research, said suggestions that the virus was weakening were "not supported by anything in the scientific literature and also seem fairly implausible on genetic grounds."
