The Indian Institute of Technology (IIT), Kharagpur has developed software that will be beneficial in detecting diabetic retinopathy, a disease that can lead to loss of eyesight, in a patient in the early stages, reports PTI.

According to IIT-K's Assistant Professor (Medical Science & Technology) Chandan Chakraborty, the disease, whose root cause is diabetes, can be detected as well as categorised by just scanning the retina and taking multiple frames of it. Read more...


Electrifying India with rice husk

The use of biomass gasification technology to convert rice husk into combustible gases and drive a generator to produce clean electricity at affordable rates, has been attracting considerable interest in the energy sector, reports Business Standard.

This technology is being promoted by Husk Power Systems, founded in 2007 by a US-trained engineering graduate Gyanesh Pandey and his friend Ratnesh Yadav

According to Pandey, for more than 125,000 villages in India, access to electricity is a distant dream. Further, more than 25,000 villages have been declared economically impossible to reach via conventional methods. Read more...

Scientists develop device for image compression

Using a new class of artificial materials, scientists at Duke University have designed a sensor that compresses images far more efficiently than existing technologies like JPEG. The materials, called metamaterials, have exotic qualities that bend light, X-rays and radio waves in unusual ways, says a report in The New York Times.

These materials can be expected to be commercially available within two years for a wide array of applications, including radio communications, security and automotive safety.Read more...
