Mahesh Jethmalani revolts against Gadkari, resigns from BJP's national executive

Chennai, Jul 1: In a case of cluster infection, 58 of the 65 mourners who attended the funeral a Central government official, Selvam, 56, who had worked in the Ministry of Foreign Trade and who died in Coimbatore and was brought for burial at Pannavaadi near Kolathur near Mettur in Salem district, tested positive for Covid-19, after three of them initially tested positive as they neither wore face masks not observed social distancing during the funeral, sources said.

Even as Dr Vijayabaskar said AIADMK MLA from Sriperumbudur, K Palani who tested positive for Covid-19 has recovered and will be discharged from hospital in couple of days, the MIOT International Hospital in Chennai said that the State Higher Education Minister, K P Anbazhagan, who initially showed no symptoms of coronavirus, subsequently tested positive in his second sample. He was now under treatment, his condition very stable and all his vital parameters are normal, MIOT said in a statement.

In what continues to be an unrestrained run, Tamil Nadu added its biggest day-wise spike so far of 3,943 positive Covid-19 cases, while another 60 deaths due to the novel coronavirus confirmed on Tuesday took the total death toll in the state to 1,201.

Of the new positive cases, Chennai alone accounted for its highest per-day jump of 2,393 positives with the number of persons tested today across Tamil Nadu put at 30,053. The total number os Covid-19 positive cases in the State as a whole till date is racing towards the one lakh mark at 90,167.

However, these outcomes are all on anticipated lines with the ICMR's push for more aggressive testing, even if they want lockdown controls to be now more focused at the district level, and want the Chennai model to be taken to the districts.

In this backdrop, the Health minister, Dr C Vijayabaskar chaired a detailed Covid review meeting this evening through video conference with all the hospital deans and other top officials on different facets of the disease prevention and control measures and the state's overall preparedness.

Chief Minister, Mr. Edappadi K Palaniswami in a statement in Chennai assured that with the 'full lockdown' continuing in greater Chennai, parts of three neighbouring districts of Chengalpattu, Thiruvallur and Kancheepuram and parts of Madurai district till July 5, the free community kitchens for the elderly, disabled and destitute will continue to function in those places till July 5 and hygienically cooked food packets served to them.

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.

Lucknow, Jul 2: After a video showing health workers allegedly tossing bodies of coronavirus victims in a large pit in Karnataka, BSP President Mayawati on Wednesday stated that the incident is the "height of cruelty and insult to humanity".
The former UP Chief Minister demanded that the guilty must be punished.

"The tragedy that the bodies of COVID-19 victims being thrown into trenches in Ballari, Karnataka is the height of cruelty and an insult to humanity. Though incidents related to inhuman cruelty with corona patients are rampant but guilty of Ballari must be punished by the state government," Mayawati said in a tweet.

Also, in another tweet, she asked the Central government to extend the Pradhan Mantri Garib Kalyan Anna Yojana till the end of the coronavirus pandemic.

"In order to check ignominy of starvation on account of long unprecedented hardship & unemployment due to coronavirus and the subsequent nationwide lockdown, the PM Garib Kalyan Anna Yojna must continue not till November but till the end of the pandemic, this is the demand of BSP," she tweeted.
