ED files charge sheet against Raja, Kanimozhi in 2G scam

Kochi, Apr 28: The Central government on Tuesday told Kerala High Court that the Kerala government will have to take up with other states the matter pertaining to bringing back COVID-19 affected Malayali nurses.

A Division Bench of Justice PV Asha and Justice V Shircy asked the Kerala government to examine if there is any solution that may be considered and orally noted the suggestion that perhaps a video-conference may be conducted between the states on the matter.

The matter was posted for further hearing on April 30.

Counsel for the Central government said that the "Centre has issued guidelines for the protection of health workers. But in this specific case, state governments have assured that nurses are being given proper treatment."
"The plea is on apprehensions that they are not being treated well in the other states.

Centre could help if there is any necessary requirement thereafter," the Centre's counsel said.

Advocate Abraham Vakkanal, appearing for the state government, said that state chief secretary has written to Union cabinet secretary to relax travel restrictions amid COVID-19 lockdown to bring back the nurses.

Vakkanal said that the state has sought permission and is waiting for approval and will take further actions if permission is received on the matter.

Advocate Anupama Subramaniam, appearing for the petitioner, said that 68 Malayali nurses in other states have reached out to inform that they are not being given treatment and that facilities for food and shelter are also not readily available for them.

Kerala High Court had earlier asked the Centre and the state government to file their reply on the plea.

The court was hearing a petition seeking to bring COVID-19 affected Malayali nurses back to Kerala from other States considering their "poor health and working conditions".

New Delhi, Mar 4: The Supreme Court on Wednesday revoked the ban of cryptocurrency imposed by the Reserve Bank of India (RBI) in 2018.

Pronouncing the verdict, the three-judge bench of the apex court said the ban was 'disproportionate'.

The bench included Justice Rohinton Fali Nariman, Justice S Ravindra Bhat and Justice V Ramasubramanian.

The Internet and Mobile Association of India (IAMAI), whose members include cryptocurrency exchanges, and others had approached the top court objecting to a 2018 RBI circular directing regulated entities to not deal with cryptocurrencies.

Advocate Ashim Sood, appearing for IAMI, submitted that Reserve Bank of India lacked jurisdiction to forbid dealings in cryptocurrencies. The blanket ban was based on an erroneous understanding that it was impossible to regulate cryptocurrencies, Sood submitted.

The petitioners had argued that the RBI's circular taking cryptocurrencies out of the banking channels would deplete the ability of law enforcement agencies to regulate illegal activities in the industry.

IAMAI had claimed the move of RBI had effectively banned legitimate business activity via the virtual currencies (VCs).

The RBI on April 6, 2018, had issued the circular that barred RBI-regulated entities from "providing any service in relation to virtual currencies, including those of transfer or receipt of money in accounts relating to the purchase or sale of virtual currencies".

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.
