BJP MLA breaks police horse's leg during protest. Animal also anti-national'?

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 19: Senior Congress leader Kapil Sibal on Sunday asserted that every state assembly has the constitutional right to pass a resolution and seek the amended Citizenship Act's withdrawal, but if the law is declared constitutional by the Supreme Court then it will be problematic to oppose it.

His remarks came a day after he had said there is no way a state can deny the implementation of the Citizenship Amendment Act (CAA) when it is already passed by the Parliament.

"I believe the CAA is unconstitutional. Every State Assembly has the constitutional right to pass a resolution and seek its withdrawal. When and if the law is declared to be constitutional by the Supreme Court then it will be problematic to oppose it. The fight must go on!" Sibal said in a tweet.

His remarks on the CAA at the Kerala Literature Festival (KLF) on Saturday had caused a flutter as several non-BJP governments, including Kerala, Rajasthan, Madhya Pradesh, West Bengal and Maharashtra, have voiced their disagreement with the CAA as well as National Register of Citizens (NRC) and National Population Register (NPR).

"If the CAA is passed no state can say 'I will not implement it'. It is not possible and is unconstitutional. You can oppose it, you can pass a resolution in the Assembly and ask the central government to withdraw it.

"But constitutionally saying that I won't implement, it is going to be problematic and going to create more difficulties," said the former minister of law and justice.

Bengaluru, Jul 2: Former Karnataka Chief Minister HD Kumaraswamy on Thursday accused BS Yediyurappa-led state government of "failure" to protect the citizens from coronavirus, stating that Karnataka was suffering due to lack of co-ordination in the cabinet.

In a series of tweets, the JD(S) leader slammed the state government for wasting their time in giving out contradictory statements regarding COVID-19 figures instead of learning lessons from the Kerala government.

"It is shocking to see COVID-19 patients being turned down by the hospitals due to lack of beds. The government has failed in its duty to protect the citizens. The CM and his cabinet colleagues wasted precious time in mere talking for the last three months. As the escalated Covid numbers stare them in the face, they are now helpless," Kumaraswamy wrote.

"Even when you have a proven model in Kerala government's success in Covid management, the ministers waste time in issuing contradictory statements and doing nothing. Karnataka suffers due to lack of co-ordination in the cabinet," he said.

Urging the government to act together, he said that if the government does not get its act together, the day is not far when Covid patients would be "condemned to die on the streets."

We are already seeing heart-wrenching stories of patients denied treatment," he added.

Kumaraswamy also appealed to the Karnataka government to consider the suggestions he had made earlier and not to indulge in party politics in these testing times.

"I appeal to the government to consider the suggestions I made earlier and act accordingly. This is not the time for party politics."
