GSLV-Mk-III, the first of its kind mission, is capable launching four ton class of satellites to Geosynchronous Transfer Orbit (GTO). The GSLV rocket is the first developmental flight, carrying 3,136 kg GSAT-19 satellite to a GTO.

The GSLV rocket took off from the second launch pad at SDSC SHAR in Sriharikota about 90 kilometres from north Chennai at 5.28 pm. After about 16 minutes into its flight, the rocket successfully placed GSAT-19 in its intended orbit.

Soon after the GSLV-Mk-III mission success Indian Space Research Organisation (ISRO) Chairman A.S.Kiran Kumar said it was a historic day.

Stating that the heavy rocket was designed in 2002, Kiran Kumar said that after a gap of 15 years, the ISRO team were able to achieve the successful launch of GSLV-Mk-III.

He congratulated the entire ISRO team which worked hard on the GSLV mission.

ISRO sources said that the design and development of GSLV Mk III is based on ISRO's rich experience in handling solid, liquid and cryogenic rocket propulsion technologies. The first suborbital test flight of GSLV Mk- III was successfully conducted on December 18, 2014.

GSAT-19 satellite with a lift-off mass of 3136 kg, is the communication satellite of India, configured around the ISRO"s standard I-3K bus.

GSAT-19 carries Ka/Ku-band high throughput communication transponders. Besides, it carries a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of charged particles and the influence of space radiation on satellites and their electronic components.

GSAT-19 also features certain advanced spacecraft technologies including miniaturised heat pipe, fibre optic gyro, Micro Electro-Mechanical Systems (MEMS) accelerometer, Ku-band TTC transponder, as well an indigenous Lithium-ion Battery.

New Delhi, Jul 13: The Income Tax Department has facilitated a new functionality for banks and post offices to ascertain TDS applicability rates on cash withdrawal of above Rs 20 lakh in case of a non-filer of the income-tax return and that of above Rs 1 crore in case of a filer of the income-tax return.

In a statement, the Central Board of Direct Taxes (CBDT) said that now banks and post offices have to only enter the PAN of the person who is withdrawing cash for ascertaining the applicable rate of TDS.

So far, more than 53,000 verification requests have been executed successfully on this facility, a statement by the CBDT said.

"CBDT today said that this functionality available as 'Verification of applicability u/s 194N' on www.incometaxindiaefiling.gov.in since 1st July 2020, is also made available to the Banks through web-services so that the entire process can be automated and be linked to the Bank's internal core banking solution," it said.

On entering PAN by the bank or the post office, a message will be instantly displayed on the departmental utility: "TDS is deductible at the rate of 2 per cent if cash withdrawal exceeds Rs 1 crore", in case the person withdrawing cash is a filer of the income-tax return.

In case the person withdrawing cash is a non-filer of income tax return, the message shown would be: "TDS is deductible at the rate of 2 per cent if cash withdrawal exceeds Rs 20 lakh and at the rate of 5 per cent if it exceeds Rs 1 crore."

The CBDT said that the data on cash withdrawal indicated that huge amount of cash is withdrawn by the persons who have never filed income-tax returns.

To ensure filing of return by these persons and to keep track on cash withdrawals by the non-filers, and to curb black money, the Finance Act, 2020 with effect from July 1, 2020 further amended IT Act to lower threshold of cash withdrawal to Rs 20 lakh for the applicability of this TDS for the non-filers and also mandated TDS at the higher rate of 5 per cent on cash withdrawal exceeding Rs 1 crore by the non-filers.

Social media platform WhatsApp assured the Supreme Court on Wednesday that it will not roll out its payment services without complying with all payment regulations and norms in the country.

A bench headed by Chief Justice S.A. Bobde and comprising Justices Indu Malhotra and Hrishikesh Roy took up the matter through video conferencing. Senior advocate Kapil Sibal, representing the social media platform, said "WhatsApp Inc makes a statement on behalf of his client that they will not go ahead with the payments' scheme without complying with all the regulations in force."

The statement was made during the hearing of a petition seeking a ban on payment through WhatsApp, as it does not conform to the data localization norms. The top court took the assurance made by WhatsApp on record.

WhatsApp made the statement during the hearing of a plea seeking a ban on its payment service, for not being in line with data localization norms.

In 2018, WhatsApp was granted a beta licence to launch its payment service, but a dedicated and separate app is yet to be launched. A petition was moved in the apex court that WhatsApp's existing model for its payments service should be declared inconsistent with the Unified Payment Interface (UPI) Scheme, as a separate dedicated app has not been offered by the company.

The petitioner NGO, Good Governance Chambers, argued that the National Payments Corporation of India (NPCI) and the Reserve Bank of India (RBI) must change its model on the lines of the UPI payment scheme, and its operations may be suspended until these conditions are met.

The apex court today asked the Centre, Facebook and WhatsApp to file their replies within three weeks and it will take up the matter thereafter. The court noted that the government may process the applications filed by WhatsApp in accordance with the law and there is no stay on the same. Facebook was represented by senior advocate Arvind Datar.

The petitioner argued that lapses have been found in relation to WhatsApp's claims of having a secure and safe technological interface for securing sensitive user data.

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.
