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.

YouTube Rolls Out Supervised Children’s Accounts Across MENA

An industry-first feed timer lets parents cap Shorts scrolling. Access can also be switched off entirely ahead of exam season.

YouTube has launched supervised kid accounts across the Middle East and North Africa, giving parents a way to hand their children the main YouTube app without handing over all of it. Announced in Dubai on July 2, the accounts are built directly into the platform rather than the standalone YouTube Kids app, and are aimed at families who feel a child has outgrown the curated library but isn’t ready for the open feed.

Parents can choose from three content settings, each broadly aligned with international content ratings. Explore covers educational videos, tutorials, arts and crafts, and dance. Explore More adds gaming and live streams. Most of YouTube opens up almost everything except videos rated 18+ or deemed inappropriate for supervised accounts.

The standout tool is an industry-first Shorts feed timer, which lets parents set daily limits on short-form scrolling. Set it to zero and Shorts disappears altogether – a lever YouTube suggests parents might pull ahead of exam season. Other protections are on by default for all users under 18: “Take a Break” and “Bedtime” reminders, no personalized ad targeting, autoplay switched off, and no ability to upload videos or write comments. The accounts are optional, and parents can end supervision at any time.

The kid accounts join supervised teen accounts already available across the region, which notify parents by email when a teenager uploads a video or starts a live stream.

“YouTube has been a huge part of families’ lives across this region for over 20 years,” said Javid Aslanov, head of YouTube Middle East and North Africa, citing Kantar research showing 95% of viewers in Saudi Arabia and the UAE agree YouTube has top content in education and learning.

“It’s essential that we protect young people in – not from – the digital world,” added Garth Graham, YouTube’s head of health.

The new settings are rolling out gradually across the MENA, including the Kingdom of Saudi Arabia, Oman, Kuwait, Qatar, Bahrain, Jordan, Lebanon, Egypt, Tunisia, Algeria, and Iraq. The latest features can be set up through Family Center in the YouTube app or via Google Family Link.
