Bengaluru, Jan 3: Prime Minister Narendra Modi on Friday called on young scientists of India to "Innovate, Patent, Produce and Prosper," and said these four steps would lead our country towards faster development. The Prime Minister also stressed on the need to transform the landscape of Indian science, technology and innovation.

"The growth story of India depends on its success in the science and technology sector. There is a need to transform the landscape of Indian science, technology and innovation," Modi said.

Speaking after inaugurating the 107th Session of Indian Science Congress, he said, "My motto for the young scientists in this country is -Innovate, Patent, Produce and Prosper. These four steps will lead our country towards faster development."

"If we innovate we will patent and that in turn will make our production smoother and when we take these products to the people of our country, I'm sure they will prosper," he said, adding that innovation for the people and by the people is the direction of our new India. The Prime Minister also said he was happy to learn that India's ranking has improved in the Global Innovation Index to 52.

"Our programmes have created more technology business incubators in the last five years than in the previous 50 years. I congratulate our scientists for this achievement," he added.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

New Delhi, Feb 1: An extremist today fired shots at anti-CAA protesters at Shaheen Bagh in Delhi, just three days after another extremist fired at protesters at nearby Jamia Millia University. This is the second daylight shooting in which the police caught the man only after the shots were fired.

The man, apparently a fan of BJP leaders including Narendra Modi and Amit Shah, shouted "Jai Sri Ram" as he fired shots standing near police barricades put up at the south Delhi locality where hundreds of women and children have sat on the road in protest for more than a month. He was caught by the police. No one was injured. 

The shooter was also heard saying: "Humare desh mein sirf Hinduon ki chalegi aur kisi ki nahi (in our country only Hindus will prevail)." He had allegedly come to the area in an auto.

A witness said the man fired two-three times, standing right next to the police, not at the spot of the protest but close enough to a large crowd of unarmed men, women and children. 

"We suddenly heard gunshots. This person was shouting Jai Shri Ram. He had a semi-automatic pistol and he fired two rounds. The police were standing just behind him," said the witness, a volunteer at the protest.

"When his gun jammed, he ran. He tried to fire again, then tossed the gun into the bushes and tried to escape. Some of us and the police caught him, the police dragged him away," he added. Protesters questioned whether the police were more focused on keeping an eye on them rather than tackling crimes like this.

Police officer Chinmay Biswal said the man had fired shots in the air. "The man had resorted to aerial firing. Police immediately overpowered and caught him," he said.

This incident - the second shooting in Delhi at an anti-CAA protest -- has chilling similarities to the one that took place just two km away at Jamia university on Thursday, when a 17-year-old Class 12 boy from Uttar Pradesh fired a crude pistol at unarmed protesters with dozens of policemen behind him, watching. The teen, who left home claiming he was going to school, took a bus to Delhi intending to target Shaheen Bagh but landed at Jamia next-door after an auto-driver dropped him off there to avoid the traffic chaos.

The shootings have taken place in quick succession after controversial slogans of "Goli Maaro Sa***n Ko (shoot the traitors)" were chanted on Monday at a Delhi campaign rally of Anurag Thakur, the Union Minister of State for Finance, who was part of the team involved in Budget 2020 announced today.

Mr Thakur was banned from campaigning in Delhi for three days for egging on BJP workers to shout the "Goli Maaro" slogan.

Delhi Chief Minister Arvind Kejriwal slammed Home Minister Amit Shah, to whose ministry the Delhi Police reports to, over the two shooting incidents. "What have you done to our Delhi, Amit Shah ji? Bullets are being fired in broad daylight... Law and order is being criticised constantly. Elections will come and go, politics will keep happening, but for the sake of the people of Delhi, please focus on fixing law and order," he tweeted.

The Shaheen Bagh protest has attracted attention from across the country in the protests against the CAA or the Citizenship (Amendment) Act, which makes religion a criterion for citizenship. Critics say the law discriminates against Muslims as only non-Muslims from neighbouring Pakistan, Afghanistan and Bangladesh can become Indian citizens if they fled religious persecution and entered India before 2015.

Of late, critics of the Shaheen Bagh protests, mainly pro-CAA activists, have attacked the month-long sit-in on a key road in Delhi connecting to Noida. They say the protest has become a traffic nightmare for commuters.
