New Delhi, Jul 24: India reported the highest single-day spike of 49,310 coronavirus cases on Friday, according to the Union Ministry of Health and Family Welfare.

The total COVID-19 positive cases stand at 12,87,945 including 4,40,135 active cases, 8,17,209 cured/discharged/migrated.
With 740 deaths in the last 24 hours, the cumulative toll reached 30,601.

Maharashtra has reported 3,47,502 coronavirus cases, the highest among states and Union Territories in the country. A total of 1,92,964 cases have been reported from Tamil Nadu till now, while Delhi has recorded 1,27,364 coronavirus cases.

According to the Indian Council of Medical Research (ICMR), 3,52,801 samples were tested for coronavirus on Thursday and overall 1,54,28,170 samples have been tested so far. 

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.

Mumbai, Apr 14: Activist and scholar Anand Teltumbde was arrested by the National Investigation Agency (NIA) on Tuesday after he surrendered before it in connection with the Elgar Parishad-Maoist links case.

Teltumbde surrendered at the NIA office at Cumbala Hill in south Mumbai following the Supreme Court's directives.

He was subsequently arrested by the NIA and shall be produced before a court here shortly, an official said.

Earlier, the scholar reached the NIA office in the afternoon along with his wife Rama Teltumbde and brother-in- law and Dalit leader Prakash Ambedkar.

Anand Teltumbde is the grandson-in-law of Dalit icon Dr B R Ambedkar, whose 129th birth anniversary is being observed on Tuesday.

Civil rights activist Gautam Navlakha, a co-accused in the case, also surrendered before the NIA in Delhi. His anticipatory bail plea was also rejected by the apex court.

According to the official, Navlakha will be produced before the court in Mumbai through video conference.

The Supreme Court on March 17 this year rejected the pre-arrest bail pleas of Anand Teltumbde and Gautam Navlakha, and directed them to surrender before the investigating agency.

Teltumbde, Navlakha and nine other civil liberties activists have been booked under the stringent provisions of Unlawful Activities Prevention Act (UAPA) for having alleged Maoist links and conspiring the overthrow the government.

The apex court while rejecting Teltumbde and Navlakha's bail pleas on March 17, directed them to surrender before the prosecuting agency withing a period of three weeks.

The duo later sought extension of the time.

On April 9, the Supreme Court extended the time by one week by way of last chance.

The activists were booked initially by Pune Police following violence that erupted at Koregaon-Bhima there.

According to police, the activists made inflammatory speeches and provocative statements at the Elgar Parishad meet held in Pune on December 31, 2017, which triggered violence the next day.

The police also said these activists were active members of banned Maoist groups.

The case was later transferred to NIA. Teltumbde and Navlakha were given interim protection by the Bombay High Court while their pre-arrest bail pleas were being heard.

After the high court rejected their applications, the duo approached the Supreme Court.
