Parliament washout: PM to 'stage' fast on Apr 12

New Delhi, Jul 13: The Telecom Regulatory Authority of India (TRAI) has blocked Bharti Airtel's Platinum and Vodafone Idea's RedX premium plans that offer faster data speeds and priority services to customers as both the plans were violating net neutrality norms.

The telecom watchdog has asked Bharti Airtel to explain within seven days how such a similar plan being launched does not violate the rules of net neutrality.

Vodafone Idea's RedX plan has been in the market since November 2019. They made some modifications in May 2020 and the Bharti Airtel was soon going to launch a similar plan.

According to TRAI, the higher speed for premium customers discriminate against others and violates net neutrality.

Responding to TRAI's move, Airtel spokesperson said: "We are passionate about delivering the best network and service experience to all our customers. This is why we have a relentless obsession to eliminate faults and have been consistently recognised by international agencies as the best network in terms of speed, latency and video experience."

"At the same time, we want to keep raising the bar for our post-paid customers in terms of service and responsiveness. This is an ongoing effort at our end," the spokesperson said.

Thiruvananthapuram, Mar 18: To raise awareness about protective measures against coronavirus, Kerala Police released a dance video on the State Police Media Centre's Facebook page promoting the washing of hands, here on Tuesday.

In the video, the police officers were seen dancing to the tunes of Kalakkatha from the Malayalam action-drama thriller Ayyappanum Koshiyum while demonstrating the right technique for washing hands.

The video gained over 27,000 likes and over 2,400 comments and more than 33,000 netizens shared the video.

The video has received a positive response with users congratulating Kerala Police for the initiative.

"Congrats Kerala police media for this kind of initiative," one user commented on Facebook. Another user thanked the police in the comments section saying, "Super super thanks to KL (Kerala) police."

The number of people who have tested positive for the coronavirus in Kerala is 25.

The total number of confirmed COVID-19 cases in India has reached 147, including 122 Indians and 25 foreign nationals, said the Ministry of Health and Family Welfare earlier today.

Globally, the virus has infected more than 184,000 people and killed more than 7500, as per the data available on the World Health Organisation website.

Toronto, May 7: Scientists have uncovered how bats can carry the MERS coronavirus without getting sick, shedding light on what triggers coronaviruses, including the one behind the COVID-19 pandemic, to jump to humans.

According to the study, published in the journal Scientific Reports, coronaviruses like the Middle East respiratory syndrome (MERS) virus, and the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats.

While these viruses can cause serious, and often fatal disease in people, bats seem unharmed, the researchers, including those from the University of Saskatchewan (USask) in Canada, said.

"The bats don't get rid of the virus and yet don't get sick. We wanted to understand why the MERS virus doesn't shut down the bat immune responses as it does in humans," said USask microbiologist Vikram Misra.

In the study, the scientists demonstrated that cells from an insect-eating brown bat can be persistently infected with MERS coronavirus for months, due to important adaptations from both the bat and the virus working together.

"Instead of killing bat cells as the virus does with human cells, the MERS coronavirus enters a long-term relationship with the host, maintained by the bat's unique 'super' immune system," said Misra, one of the study's co-authors.

"SARS-CoV-2 is thought to operate in the same way," he added.

Stresses on bats, such as wet markets, other diseases, and habitat loss, may have a role in coronavirus spilling over to other species, the study noted.

"When a bat experiences stress to their immune system, it disrupts this immune system-virus balance and allows the virus to multiply," Misra said.

The scientists, involved in the study, had earlier developed a potential treatment for MERS-CoV, and are currently working towards a vaccine against COVID-19.

While camels are the known intermediate hosts of MERS-CoV, they said bats are suspected to be the ancestral host.

There is no vaccine for either SARS-CoV-2 or MERS, the researchers noted.

"We see that the MERS coronavirus can very quickly adapt itself to a particular niche, and although we do not completely understand what is going on, this demonstrates how coronaviruses are able to jump from species to species so effortlessly," said USask scientist Darryl Falzarano, who co-led the study.

According to Misra, coronaviruses rapidly adapt to the species they infect, but little is known on the molecular interactions of these viruses with their natural bat hosts.

An earlier study had shown that bat coronaviruses can persist in their natural bat host for at least four months of hibernation.

When exposed to the MERS virus, the researchers said, bat cells adapt, not by producing inflammation-causing proteins that are hallmarks of getting sick, but instead by maintaining a natural antiviral response.

On the contrary, they said this function shuts down in other species, including humans.

The MERS virus, the researchers said, also adapts to the bat host cells by very rapidly mutating one specific gene.

These adaptations, according to the study, result in the virus remaining long-term in the bat, but being rendered harmless until something like a disease, or other stressors, upsets this balance.

In future experiments, the scientists hope to understand how the bat-borne MERS virus adapts to infection and replication in human cells.

"This information may be critical for predicting the next bat virus that will cause a pandemic," Misra said.
