AI Technology Could Help Protect Water Supplies

Moving forward, the goal is an AI system to continuously monitor water flowing through a microscope for a wide range of contaminants and microorganisms

Researchers have developed a novel artificial intelligence (AI)-based software that could make monitoring at water treatment plants cheaper and easier and help safeguard public health.

The new technology is capable of identifying and quantifying different kinds of cyanobacteria, or blue-green algae, as a threat to shut down water systems when it suddenly proliferates.

“We need to protect our water supplies. This tool will arm us with a sentinel system, a more rapid indication when they are threatened,” said Monica Emelko, Professor at the University of Waterloo in Ontario, Canada.

The operational AI system uses software in combination with a microscope to inexpensively and automatically analyse water samples for algae cells in about one to two hours, including confirmation of results by a human analyst.

The AI system would provide an early warning of problems since testing could be done much more quickly and frequently than current existing methods, said Alexander Wong, Professor at the varsity.

Moving forward, the goal is an AI system to continuously monitor water flowing through a microscope for a wide range of contaminants and microorganisms.

The researchers estimate it may take two to three years to refine a fully commercial sample testing system for use in labs or in-house at treatment plants. The technology to provide continuous monitoring could be three to four years away.

“It’s critical to have running water, even if we have to boil it, for basic hygiene,” Emelko said. (IANS)

New AI Model by Google Can Help Detect Diabetic Retinopathy

For this purpose, it recently launched the "Google AI Impact Challenge"

Google has developed an Artificial Intelligence (AI) model that can detect diabetic retinopathy with a level of accuracy on par with human retinal specialists, the technology giant said.

Google is working on “rolling out this diabetic retinopathy initiative in clinics in India with Verily” — an Alphabet-owned company which works on life sciences research and development, Kent Walker, SVP of Global Affairs at Google, wrote in a blog post on Thursday.

More than 400 million people in the world have diabetes. A third of them have diabetic retinopathy — a complication that can cause permanent blindness.

“Using the new assistive technology, doctors and staff can screen more patients in less time, sparing people from blindness through a more timely diagnosis,” Walker said.

While the blindness can be prevented, diabetic retinopathy often goes undetected because people do not always get screenings.

“In major part, this is due to limited access to eye care specialists and staff capable of screening for the disease. This is a problem that AI can help us solve,” Walker said.

“Deploying this technology in underserved communities that don’t have enough eye specialists could be life-changing for many,” Walker added.

Google began work on the model in collaboration with eye specialists in India and the US a few years back. They developed an AI system to help doctors analyse images of the back of the eye for signs of diabetic retinopathy.

“The results were promising,” Walker noted, while adding “we should work to make the benefits of AI available to everyone”.

Google has for several years applied AI research and engineering to projects in Asia Pacific with positive societal impact, including stopping illegal fishing in Indonesia, forecasting floods in India, and conserving native bird species in New Zealand, the blog post read.

Besides healthcare, the tech giant also wants to support more Asia Pacific organisations in using AI to help society by engaging with governments, non-profit organisations, universities and businesses.

For this purpose, it recently launched the “Google AI Impact Challenge”.

“Selected organisations who apply to the challenge will receive support from Google’s AI experts and Google.org grant funding from a $25 million pool,” Walker said. (IANS)
