Tension at Mutt as seer's 'sleaze' video goes viral

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 26: While the humans are on lockdown and spending time with their families, animals are free and without any fear roaming around on the otherwise busy roads. From Malabar civets to large Indian bisons, animals are enjoying this time.

Indian Forest Officer Susanta Nanda recently shared a video with the caption, "Indian bison( the gaur) goes for a street walk. The largest extant Bovine, is native to South and Southeast Asia. It can be very aggressive. Rare to see in markets."

The 8-second video shows the large animal freely walking in the market area of Chikmagalur district, Karnataka, while the few onlookers on the road get aside and watch the Bison with utmost amazement.

The videos of animals having a gala time on the roads have become common. After the video was posted online, it became a hit. The clip garnered over 3.1k views and over 100 retweets.

Twitter is amazed at the video. Have a look at the comments.

One user wrote, "Oh! We should vacate this place for them. Guess humans have stayed for too long."

Another Twitter user wrote, "That’s one thing people would follow social distancing with!"

Mysuru, Jan 22: Former Chief Minister Siddaramaiah here on Wednesday urged the state government to initiate an unbiased investigation into the Mangaluru airport bomb case.

Addressing media persons here, he said, “The incident has created panic among the public and such incidents are being repeated due to the failure of intelligence agencies of the state”.

On accused Aditya Rao, the suspect in the case, who surrendered before Bengaluru police on Wednesday morning, the senior Congress leader said, “I have not yet gathered complete information about the accused in the case, therefore I would not like to comment about him.”
