Jin Shang, a professor of biochemical engineering at the University of Western Ontario, has invented a contact lens that changes color when sugar levels change in the blood. Those suffering from diabetes need to draw blood to check sugar levels. Nanoparticles implanted in contact lenses interact with glucose molecules in tears. This interaction changes the color of the lens to indicate varying sugar levels. This new medical invention could eliminate the need to draw blood to monitor glucose.

Alcohol Makes Rats Turn To Cocaine The most common research involving alcohol typically concerns its effect on humans. One area of particular interest is its addictiveness and if alcohol will leave you more vulnerable to drug use. A study from 2017 supported this idea by showing that drunk rats like  cocaine .

This study suggests that, at

As the second most populous country in the world, India is teeming with creativity and innovation. Indeed, it was in India that the cataract surgery was first performed, and also where the concept of zero originated. With a focus on the here and now, this list highlights five out-of-the-box inventions that are posed to help citizens across the globe. This selection represents the tip of the iceberg - if you know of more modern-day inventions from India, please share them with us in the comments section below. 1. GREEN LIVING –  STREETS MADE OF PLASTIC Like many countries, India grapples with an excess of plastic waste. Chemistry professor  Rajagopalan Vasudevan  devised a way to transform common plastic litter into a substitute for bitumen — the main ingredient in asphalt used for road construction. Known as the “Plastic Man,” Vasudevan’s ingenious invention has already paved 3,000 miles (5,000 kilometers) of plastic thoroughfares in at least 11 Indian states. Streets of p
