Sushant Singh had posted heartbroken message after Udupi girl Disha Salian's death

Tumakuru, Mar 1: A leopard killed 30-month-old kid when she was playing outside her home in Baichnehalli village in Hebbur Hobli in Tumakuru district, police said on Sunday.

Police said that the deceased has been identified as Chandana. The incident happened on Saturday evening.

Forest and police officials visited the spot. A case has been registered in this connection.

Karnataka Minister for Forest Ananda Singh issued a shoot at sight order for the leopard which killed a 30-month-old boy while playing in front of his house on Sunday.

Speaking to newsmen after visiting the Bichenahalli where the kid was killed, he said that the operation will begin on Monday. The kid was dragged by the leopard and killed Saturday night.

Earlier also the same leopard had killed five-year-old child in the district, he added.

Mangaluru, Jun 1: A youth was hacked to death and two others suffered critical injuries following a fight between two gangs at Yekkaru Devaragudde near Kateel under the limits of Bajpe police station last night.

The deceased has been identified as Keertan (20), a resident of Marakada. The injured are Nitin (20) and Manesh (20). It is learnt that old animosity led to the attack and murder.

According to sources, members of both gangs were friends in the past. They had become enemies of each other following a fight regarding sand mining.

Sources said that Keertan, Nitin, and Manesh had reportedly invited their rival gang to Devaragudde for some discussion. A verbal friction arose between the two gangs and it culminated in the attack by the rival gang members with daggers. Keertan reportedly died on the sport. The other two were taken to hospital.

The accused fled the scene soon after committing the crime. A case has been registered at Bajpe police station. A manhunt has been launched to nab the accused.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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