'MNCs should stop treating Indians as guinea pigs'

New Delhi, Jul 8: India has reported a spike of 22,752 COVID-19 cases in the last 24 hours, taking the country's coronavirus tally to 7,42,417 on Wednesday, informed the Union Ministry of Health and Family Welfare.

Out of the total cases reported, 4,56,830 patients have been cured/discharged from the disease while one patient has been migrated, the Health Ministry informed.

It added that there are 2,64,944 active cases in the country.

482 deaths reported in the last 24 hours due to COVID-19 in the country, taking India's death toll to 20,642.

According to the Union Health Ministry, Maharashtra continues to be the worst affected state reporting 2,17,121 coronavirus cases and 9,250 fatalities.

Tamil Nadu -- the second worst-affected state from COVID-19 -- has a total of 1,18,594 cases and 1,636 deaths due to coronavirus.

While Delhi has a total of 1,02,831 COVID-19 cases including 3,165 deaths.

The Indian Council of Medical Research on Wednesday informed that a total of 1,04,73,771 samples tested for COVID-19 up to July 7. Of these, 2,62,679 samples were tested on Tuesday.

Mar 11: In a bid to keep its flock together, the crisis-hit Madhya Pradesh Congress has decided to shift its 92 MLAs either to Jaipur or some other place.

The move comes after 22 Congress MLAs loyal to former Union minister Jyotiraditya Scindia resigned on Tuesday, pushing the 15-month-old Kamal Nath government to the brink of collapse.

"We are going to take our 92 MLAs and those supporting our Madhya Pradesh government to a hotel," a senior Congress leader said on Wednesday.

The legislators would be taken either to Jaipur or some other Congress-ruled state like Chhattisgarh, a party source said.

Apart from its own MLAs, the Congress is also keeping a close watch on four Independents who are supporting the party-led state government.

On Tuesday, 22 Congress MLAs from Madhya Pradesh resigned soon after Scindia quit the party.

The development reduced the Congress government in the state to minority.

The state Congress unit is now making all efforts to save the Kamal Nath-led government.

The BJP on Tuesday night shifted its MLAs to Manesar at Gurugram in Haryana, sources in the saffron party said.

The Congress, whose tally before the rebellion was 114, has a wafer-thin majority in the Madhya Pradesh Assembly whose current effective strength is 228.

It also has the support of four Independents, two BSP legislators and one SP MLA, but some of them are now likely to switch sides to the BJP.

The BJP has 107 seats in the state Assembly.

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.
