Bengaluru, Jan 11: India's maiden manned space mission 'Gaganyaan' is set for December 2021 launch and is likely to include a woman astronaut, Indian Space Research Organisation Chairman K Sivan said Friday.

Gearing up for the mission, announced by Prime Minister Narendra Modi, the ISRO has set up a new centre to facilitate the manned voyage involving a three-member crew, he said.

"We have put everything in place. Gaganyaan has highest priority for 2019. We are planning to have first unmanned mission in December 2020 and second for July 2021. Once we complete this the manned mission will happen in December 2021. The entire team is geared up to achieve this target," Sivan said.

The Union Cabinet gave its nod for the Rs 9,023 crore programme recently, he said, briefing reporters about the achievements of the city-headquartered ISRO in the previous year and the future programmes.

In his Independence Day address last year, Modi had announced that the mission would be undertaken by 2022 using ISRO's own capabilities.

"We have resolved that by 2022, when India celebrates 75 years of Independence or maybe even before that, certainly some of our young boys and girls will unfurl the Tricolour in space," he had said in his speech from the ramparts of the Red Fort 

To a question, the ISRO chief said, "We want women astronauts also should be there. That is our aim. In my opinion, we have to train both men and women. The PM has told brother and sister (boys and girls). We will be happy to do that... but it involves training and other things." 

He said a major expansion was in the offing with the launch of Gaganyaan.

"There are two aspects to Gaganyaan -- engineering and human. This is a major expansion because it is not only launching human into the space but a space station. Human programme is a major turning point," Sivan said.

He said the objective of the mission is to carry a three-member crew to low earth orbit and return them safely to a predefined destination on earth.

Sivan said ISRO had launched the Human Space Flight Centre to take care of all the things related to the manned space programme.

The centre will have senior scientist Unnikrishnan Nair as its director while the project director would be Dr R Hutton, the ISRO chief said.

He said the crew members for Gaganyaan would be from India and include one from the Indian Air Force.

Gaganyaan initial training will be in the country but advanced training might be abroad, maybe in Russia, Sivan said.

On successful completion of the mission, India would become the fourth nation in the world to achieve the feat, he said.

New Delhi, Jan 19: Messaging service WhatsApp which on Sunday faced issues in transmitting multimedia content including pictures and images, prompting social media users to share hilarious memes and messages, resumed regular services after over two hours.

#WhatsAppDown was the trending hashtag on Twitter for most part of Sunday afternoon in India along with several other countries such as Brazil, Europe and also parts of Middle-East including UAE, reported downdetector.in, a realtime problem and outage monitoring website.

Users of the popular messaging app were unable to send media files, stickers and GIFs.

Most users immediately went to Twitter to find out about the problem and check if others were facing the same issue.

Numerous tweets and memes took over the internet as soon as the news broke about the WhatsApp tech issue. After around two hours of technical glitch, the app resumed full service.

Even after full recovery of media transfer, people globally still continued checking the status of the messaging app.

WhatsApp has been one of the prime messaging apps since May 2009 and has recently collaborated with Facebook.

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.

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.
