Scientists Discover Bacteria That Makes Toxic Water Safe To Drink

Treating wastewater using the newly discovered bacteria doesn’t require expensive equipment and chemicals, so it can be done at scale at a reasonable price.

UNICEF and the World Health Organization (WHO) estimate that 1 in 3 people in the world don’t have access to safe drinking water. In places where safe drinking water is scarce, nutrition-related problems are prevalent, children have trouble staying focused in school, and diseases caused by bacteria and unhygienic practices are common.

Solving this global problem is one of the greatest challenges of our time, which is why many scientists from around the world are researching all kinds of methods for making unsafe water drinkable.

Among them are Dr. Vishal Mishra and PhD student Veer Singh from the Indian Institute of Technology, Banaras Hindu University (IIT-BHU). Recently, the two scientists have published a paper in the Journal of Environmental Chemical Engineering, describing their discovery of a bacteria capable of separating toxic metal from wastewater and making it safe to drink.

They named the bacteria “Microbacterium paraoxydans strain VSVM IIT (BHU),” and described it as very effective when it comes to the elimination of hexavalent chromium, a known carcinogen and a reproductive toxicant present in many water sources around the world.

“It is very effective for removal of hexavalent chromium from wastewater compared to other conventional methods,” said Dr. Mishra. “This bacterial strain showed fast growth rate in the Hexavalent chromium Cr (VI) containing aqueous medium and gets easily separated from the aqueous medium after the treatment process”.

Treating wastewater using the newly discovered bacteria doesn’t require expensive equipment and chemicals, so it can be done at scale at a reasonable price.

In India, the country from where the two scientists come from, less than 50 percent of the population has access to safely managed drinking water, and water contamination is present in more than 1.96 million dwellings. Hopefully, this and other similar discoveries will eventually help reduce these numbers to zero.

Facebook has announced that it wants to create 10,000 jobs in the European Union (EU) to build its metaverse, a virtual reality space in which users can interact with a computer-generated environment and other users.

The concept of the metaverse can be traced to Neal Stephenson’s 1992 cyberpunk novel Snow Crash. In the novel, the metaverse is a virtual shared space that appears to its users as an urban environment. This space is accessed through personal terminals connected to virtual reality goggles.

Sound familiar? That’s because the metaverse is quickly becoming a reality thanks to companies like Oculus, a subsidiary of Facebook, and the combined effort of developers and content creators from around the world.

By creating thousands of new high-skilled jobs within the EU over the next five years, Facebook wants to accelerate the development of the metaverse to usher in a new phase of interconnected virtual experiences, enabled by technologies like virtual and augmented reality.

“At its heart is the idea that by creating a greater sense of ‘virtual presence,’ interacting online can become much closer to the experience of interacting in person,” said Nick Clegg, Facebook’s vice-president of global affairs. “The metaverse has the potential to help unlock access to new creative, social and economic opportunities”.

According to the official announcement, Facebook decided to invest in the EU because the company believes that European talent is world-leading, supported by first-class universities. Facebook also mentioned the role European policymakers are playing in shaping the internet, so it’s likely that the investment has a political dimension to it.

Aware of its tarnished reputation, the social media giant stressed that no single company would own and operate the metaverse — just like no single company owns the internet today. Of course, that doesn’t change anything about the fact that Facebook wants to play a huge role in it.

Earlier this year, Mark Zuckerberg told his employees that Facebook is becoming a metaverse company with the goal of building a set of connected social apps and supporting hardware. The recently released Horizon Workrooms remote collaboration app for the Oculus Quest 2 headset can be seen as an early piece of the much larger puzzle the metaverse will become in the future.
