Modi copying my scheme of adopting villages, building toilets: Mulayam

Kochi, Jan 21: A special court here on Tuesday sent two students, who were arrested under the Unlawful Activities Prevention Act (UAPA) case in Kozhikode last November, to the custody of National Investigation Agency (NIA) for a day.

The NIA court ordered that the duo, who were in judicial custody till now, to be produced before it tomorrow.

In its application, the NIA had said that the accused must be interrogated on the basis of digital records and sought custody of the duo for a week.

However, the defendant argued that no new evidence had been found against the accused and therefore no custody should be granted.

During an earlier hearing, the two had told the court, "We are not Maoists. We are CPI (M) activists. The Chief Minister, who says we are Maoists, should bring proof of whom we killed and where we bombed. In the last election, we have served as CPI (M), booth agents. We are the ones who went out to vote and pasted posters for the party."

The two were charged under Sections 20 (punishment for being a member of terrorist gang or organisation), 38 (offence relating to membership of a terrorist organisation) and 39 (offence relating to support given to a terrorist organisation) of the UAPA.

Allen and Thaha, students of law and journalism respectively of Kannur University, were taken into custody by the police from Pantheerankavu in Kozhikode on November 1 last year.

New Delhi, Apr 9: With an increase of 540 positive COVID-19 cases reported in the last 24 hours, India's tally of coronavirus cases has risen to 5,734, said the Ministry of Health and Family Welfare on Thursday.

Out of the 5,734 cases; 5,095 are active COVID-19 cases and 472 cases have been recovered/discharged and one case migrated.
The death toll has also risen to 166 after 17 new deaths were reported in the last 24 hours.

Maharashtra is the worst-hit state 1,135 positive cases so far and while Tamil Nadu is second with 738 positive cases. Delhi's tally has risen to 669 cases. 

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.
