To stabilise ships in oceans, water is pumped in or out of the ballast depending on the other loads on the ship. If the water being pumped out is filtered ships can save the oceans from the emerging microplastic pollution, say Indian scientists.
Madhu Keerthana from IIT Kharagpur and collaborators from Finland have come up with an automated system to identify heart problems from speech signals of patients. A medical technology in the making.
Centralised water treatment plants in urban areas have high cost of maintenance. Researchers from IIT Madras have now come up with a solution: an optimised network of grey water and wastewater treatment plants. A must read for municipal authorities.
What do you do when you have a bumper harvest of coconuts and the price in the market goes down? Make sweet, crisp coconut chips that can be preserved packaged and sold, say ICAR scientists. Here is the method.
Protecting furniture from fungal attacks, especially in monsoon, is a problem. It becomes more acute if the wood used is from the rubber tree. Scientists from the Institute of Wood Science and Technology now offer a solution.
The world is throwing away more than 2 million tonnes of fish scales as waste every year. Muhamed Ashraf and team from the ICAR-Central Institute of Fisheries Technology, Kochi have now found a way to convert the waste to wealth.
An estimated seven crore tonnes of food waste is thrown out by Indians every year, polluting the environment. Converting this waste into biohydrogen energy is an economic opportunity, say researchers from CSIR-IICT. Municipalities need to listen to this.
How can food industries select bananas at the right stage of ripeness for making various kinds of products? Easy, say researchers from Coimbatore. They have trained a machine learning algorithm to do just that.
Instead of polluting environment, diary wastewater can be used for electricity generation, say researchers from NIT Agarthala. Read on.
Hydrogen sulphide, toxic at high concentrations, is an important part of out physiology at very low concentrations. A sensor that is sensitive enough to detect the changes in its concentrations are important in the diagnosis of many diseases. Indian researchers have now found a way, using the chromophore of a fluorescent protein.
