Black carbon could lead to premature mortality, said a study conducted by the Department of Science & Technology-Mahamana Centre of Excellence in Climate Change Research (MCECCR) at the Banaras Hindu University.
Black carbon has significant adverse effects on human health and leads to premature mortality, said the new study, which could help in the estimation of the future burden of mortality associated with air pollutants more accurately.
The study explored the individual as well as the cumulative impact of BC aerosol, fine (PM 2.5) and coarse (PM 10) particulates, and trace gases (SO2, NO2, O3) on premature mortality in Varanasi. The findings have recently been published in the journal 'Atmospheric Environment'.

The Indo-Gangetic plain is exposed to black carbon with serious implications on regional climate and human health. However, most of the pollution-based epidemiological studies essentially relate exposure to particulate mass concentration (PM 10 and/-or PM 2.5) that invariably generalize all particulates with equal toxicity without distinguishing individuals by their source and composition, which genuinely have different health consequences.
Importantly, the health effects in terms of mortality due to black carbon aerosol exposure have never been evaluated in India. A typical urban pollution hotspot in the central Indo-Gangetic plain (IGP), Varanasi experiences very high aerosol loading and trace gas concentration throughout the year due to the prevalence of a subsidence zone and observed decadal increasing trends both in aerosol optical depth and black carbon aerosols.
The scientists from the MCECCR, supported by the climate change program of the Department of Science and Technology, utilized daily all-cause mortality and ambient air quality from 2009 to 2016 to clearly establish a significant impact of black carbon aerosols, NO2, and PM2.5 exposure on mortality.

The inclusion of co-pollutants (NO2 and PM 2.5) in the multi-pollutant model increased the individual mortality risks for black carbon aerosols. The effect of pollutants was more prominent on males in the 5-44 age group, especially during winter.
They found that the adverse effect of air pollutants is not limited to the current day of exposure, but can extend as high as up to five days. They further showed that mortality rises linearly with an increase in air pollutant levels and shows adverse impact at higher levels.
The inclusion of black carbon as a potential health hazard inspires and provides a background for more epidemiological studies to provide evidence of the health effects of air pollutants from different parts of the country.

As robots evolve to do more work around us, the UK-based humanoid robot manufacturer Engineered Arts has infused more human-like facial expressions into one of its robots, which may leave you with an eerie feeling.
In a video posted on YouTube, the robot called 'Ameca' displays various human expressions, like appearing to "wake up" from sleep, as its face shows confusion and frustration when it opens its eyes.

Once awake, 'Ameca' starts looking at its hands and arms, opens its mouth and raises its eyebrows, just like a human does.
At the end of the video, Ameca smiles and holds a welcoming hand out towards the viewer.
According to Engineered Arts, the humanoid bot is currently unable to walk and it is working towards giving it the ability in the near future.
"Designed specifically as a platform for development into future robotics technologies, 'Ameca' is the perfect humanoid robot platform for human-robot interaction," says the company.
The 'Ameca' hardware is a development based on its own research into humanoid robotics and built on its advanced 'Mesmer' technology.

Engineered Arts is slated to put 'Ameca' on display at the CES 2022 conference in Las Vegas in the US in January.
"Human-like Artificial Intelligence needs a human-like artificial body. Artificial Intelligence and Machine Learning systems can be tested and developed on Ameca alongside our powerful 'Tritium' robot operating system," the company posted on its website. (IANS/PR)

Microsoft has disrupted the activities of a China-based hacking group, gaining control of the malicious websites the group used to attack organisations in the US and 28 other countries around the world.
The Microsoft Digital Crimes Unit (DCU) said in a statement that a federal court in Virginia granted its request to seize websites of the hacking group called 'Nickel', enabling the company to cut off Nickel's access to its victims and prevent the websites from being used to execute attacks.

"We believe these attacks were largely being used for intelligence gathering from government agencies, think tanks and human rights organisations," said Tom Burt, Corporate Vice President, Customer Security and Trust at Microsoft.
Obtaining control of the malicious websites and redirecting traffic from those sites to Microsoft's secure servers will help the company protect existing and future victims while learning more about Nickel's activities.

"Our disruption will not prevent Nickel from continuing other hacking activities, but we do believe we have removed a key piece of the infrastructure the group has been relying on for this latest wave of attacks," Burt said late on Monday.
To date, in 24 lawsuits - five against nation-state actors -- Microsoft has taken down more than 10,000 malicious websites used by cybercriminals and nearly 600 sites used by nation-state actors.
"We have also successfully blocked the registration of 600,000 sites to get ahead of criminal actors that planned to use them maliciously in the future," the tech giant informed.

In some observed activity, Nickel malware used exploits targeting unpatched on-premises Exchange Server and SharePoint systems.
"However, we have not observed any new vulnerabilities in Microsoft products as part of these attacks. Microsoft has created unique signatures to detect and protect from known Nickel activity through our security products, like Microsoft 365 Defender," the company noted.
Nickel has targeted organisations in both the private and public sectors, including diplomatic organisations and ministries of foreign affairs in North America, Central America, South America, the Caribbean, Europe and Africa. (IANS/SP)
