New Delhi, Jan 20: Security has been beefed up at airports across the country after a suspicious bag was found at the Mangaluru airport on Monday.

According to Central Industrial Security Force (CISF), which guards the airports in the country, a man was captured in the CCTV dropping the bag inside Mangaluru airport.

According to the CISF DIG Anil Pandey, traces of improvised explosive device (IED) have been found from the bag.

"According to CCTV footage, a suspect kept the bag at Mangaluru airport and was then seen leaving in auto while concealing his face. The suspected object was detected timely and local bomb disposal team is working on its disposal," DIG Pandey told media.

"We have found traces of IED from a bag lying at a ticket counter in Mangaluru airport, we have safely evacuated it," DIG Pandey told media.

According to sources, initial investigations have revealed that the bag contained some type of black powder.

"Initial investigation has revealed that the bag contained a black powder which seems to be explosive, though it is yet to be cleared what kind of explosive it is," sources claimed.

"After we found the suspicious bag at Mangaluru airport, a security drill has been initiated at all the airports and CISF staff have been asked to beef up security," DIG Pandey said.

Uppinangady, Feb 9: Two members of a family were killed after the car collided with a tanker on the NH 75 at Bedrody near Uppinangady last night.

Police said on Sunday that the deceased have been identified as Jainy Saji (30) and her elder brother Jeeson (40).

Jainy and Jeeson were going to Uppinangady when a tanker, coming from the opposite direction, rammed into their car.
 

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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