Bantwal: Vigilantes attack two men for transporting cattle

Bengaluru, June 21: Three youngsters lost their lives when an alleged wheeling stunt turned near Jakkur flyover in the city today morning. 

The deceased have been identified as Mohammed Hadi, Ahmed Khan and Syed Riaz, all residents of Nagavara Govindapura.

The tragedy took place at around 6:30 a.m. While two among them died on the spot, the third one breathed his last at a hospital, soruces said.

Yelahanka traffic police have registered a case in this regard. 

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jul 17: Karnataka Minister for Health and Family Welfare B Sriramulu on Thursday clarified that his remarks have been misinterpreted, wherein he apparently said that ''only God can save people from Covid''.

The Bharatiya Janata Party leader slammed KPCC President D K Shivakumar for spreading false information and said that my words were not meant to cause panic among the masses.

''Respected Shivakumar, this is a clarification regarding my words that have been misinterpreted and misunderstood.

While responding to claims of the opposition that the government’s negligence, irresponsibility and the lack of coordination among ministers are responsible for the rise in cases in the state, I stated that ‘these accusations are far from the truth. People need to be aware and cautious to avoid the spread of the virus. This plays a vital role in controlling the pandemic. If we fail at this crucial step the situation can get complicated. And if things go worse, then only God can save us'', Mr Sriramulu said in a series of posts on Twitter
