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.

At I/O 2026, Sundar Pichai Concedes AI Must Deliver Real Value

Gemini 3.5, a personal agent called Spark, agentic shopping, and Android XR eyewear are all aimed at making AI feel useful, not just impressive.

Google’s annual I/O developer conference (I/O 2026) has recently become a status update on the same question: can the company turn its AI spending into products people use every day? This year, chief executive Sundar Pichai described Google as being in a phase of hyper progress, while conceding this is the part of the cycle where people want to see real value in the products they use on a day-to-day basis.

The strategy on display was to push agents — AI systems that act on a user’s behalf — into nearly every Google product at once. Search now has an “intelligent search box” that returns generated explainer videos alongside links. Gmail, Docs, YouTube and Maps are gaining their own agent layers, including a Docs Live feature that turns spoken instructions into drafted text with citations.

Two new models, Gemini 3.5 and a cheaper Gemini 3.5 Flash, arrived the same day. Google says 900 million people now use Gemini, and that more than 50 billion images have been generated with it. The pricing tier names are likely to confuse buyers: a new AI Ultra plan launches at $100 a month, while the older Gemini AI Ultra drops from $250 to $200.

The flashier announcements were Gemini Omni, a video generator pitched as a more realistic answer to OpenAI’s discontinued Sora 2, and Gemini Spark, a personal agent that handles recurring tasks across a user’s Google account. A new universal shopping cart lets agents complete purchases across multiple retailers from inside Google itself, placing the company between the merchant and the buyer, and also owning the checkout.

Google also confirmed its Android XR eyewear, built with Samsung and frames from Warby Parker and Gentle Monster. Audio-only glasses ship this autumn; a display-equipped version, which would superimpose live translations into the wearer’s field of view, is still in development. Both sets translate, however only the display version shows you the result.

What Pichai did not resolve is the bargain underneath all this. An agent is only useful to the degree it knows your calendar, your inbox, your shopping history and your physical surroundings. Google has now confirmed that, in time, the same context may carry advertising.
