Judicial inquiry ordered into Kishtwar violence

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.

Feb 2: The Supreme court on Monday decided to hear on March 4 a plea seeking registration of FIRs against politicians for hate speeches which allegedly led to violence in the national capital.

A bench headed by Chief Justice S A Bobde agreed to hear the plea filed by riots victims.

The petition was mentioned for urgent listing by senior advocate Colin Gonsalves, appearing for the riots victims.

Gonsalves said that the Delhi High Court has deferred for four weeks the matters related to riots in the national capital despite the fact that people are still dying due to the recent violence.

In a startling revelation, cybersecurity researchers have claimed that a hacker has posted personal details of nearly 2.9 crore Indian job seekers at one of the hacking forums on the Dark Web for free.

As part of the regular sweep over the Deep Web and Dark Web, researchers from cybersecurity firm Cyble came across an interesting item, where a threat actor posted 2.3GB (zipped) file on one of the hacking forums.

"The leak actually has a lot of personal details of millions of Indians Job seekers from different states," Cyble said in its blog on Friday.

This breach includes sensitive information such as email, phone, home address, qualification and work experience etc from job seekers spanning across states, from New Delhi to Mumbai and Bengaluru. 

Cybercriminals are always on the lookout for such personal information to conduct various nefarious activities such as identity thefts, scams, and corporate espionage.

"It appears to have originated from a resume aggregator service given the sheer volume and detailed information," it added.

Cyble indexed this information at ‘AmIbreached.com; – Cyble's data breach monitoring and notification platform.

Cyble researchers have identified a sensitive data breach on the dark web where an actor has leaked personal details of nearly 29 million Indian job seekers from various states. 

"Cyble's team is still investigating this further and will be updating their article as they bring more facts to the surface,” it said in a statement.

Cyble said it has acquired the leaked data. 

The same cyber security firm earlier exposed that Bengaluru-based edtech firm Unacademy was hacked.

According to Cyble researchers, nearly 22 million Unacademy user accounts were affected and the data was dumped and sold on Dark Web.

'We would like to assure our users that no sensitive information such as financial data or location has been breached," said Hemesh Singh, Co- Founder and CTO, Unacademy, in a statement.

In April, hackers sold personal data of a whopping 267 million Facebook users for just Rs 41,500 (approximately 500 Euros) that includes email addresses, names, Facebook IDs, dates of birth and phone numbers.

No passwords of the 267 million Facebook users were exposed by the hacker, according to Cyble.
