In a first-of-its-kind development, private city buses in Mangalore have started making a beeline to receive biofuel made out of Used Cooking Oil (UCO) from restaurants. Biofuel researchers here are set to create a unique ecosystem for disposing hazardous UCO while also creating an eco-friendly fuel for transportation fleet. The coastal district has over 100 medium to large scale eateries, and 360 private buses plying the routes. Eight years ago, the Government of Karnataka had mooted the creation of 27 to 30 biofuel research information and demonstration centres in the state. This included a unit in Nitte village, Udupi District,…

We often hear about encroachments and solid waste sounding the death knell for water bodies in Chennai. Villivakkam Lake is no exception; it shares the same plight as any other water body in the city. However, it is set to change. Corporation officials say that the transformation of this 36.5 acre lake will be revolutionary -- replete with state-of-the art recreation facilities such as walkway, gym, children's play area, library, food and play courts, open air theatre and a multipurpose lawn. Greater Chennai Corporation will adopt Bhabha Atomic Research Centre (BARC)’s natural process of treating wastewater and use it for…

Animals, including humans, are curious by nature. Science is what makes the curiosity of the human animal different from that of the others. It is the tool we have developed to explore the world to know more and answer deep and profound questions. This includes the brain asking, and answering, the question, “how does the brain work?”. This is uniquely human and makes humans human. Throughout history, however, society has had a love-hate relationship with science. In this context, society includes the state, organized religion, politics, commerce, citizens, and even scientists themselves. The state has tried to suppress and discredit…

A low-cost catalyst to produce hydrogen, which could make clean energy cheaper Scientists at the Indian Institute of Science (IISc) have developed an inexpensive catalyst, sodium cobalt metaphosphate, to produce hydrogen from water. Hydrogen is a clean energy source used in fuel cells. Sleek vehicles that run on hydrogen fuel cells have just started entering the market. The IISc scientists’ invention could be a major step in making fuel cells more affordable. Typically, ruthenium and platinum are the catalysts used to generate hydrogen from water. These catalysts are quite expensive, but without them the reaction would be slow. Sodium cobalt…

It would be hard to miss the recent additions to the streets of Chennai over the past few months. The ubiquitous presence of tiny flickering lights that belong to the many CCTV cameras placed within 50 metres of each other at most roads and intersections have attracted considerable attention and publicity. The CCTV cameras are part of an initiative launched two years ago by the Chennai Police to combat crime. Dubbed 'Third Eye’, the campaign has gained steam over the last six months or so and now covers over half the city. Who's watching? The Third Eye campaign took wings…

December 2015 -- a date that Chennai is unlikely to forget in a long time to come. The ruthlessness of nature coupled with an unprepared civic administration created one of the worst floods that any city in India has ever seen. But if there was anything good about the floods and their aftermath, it was the awareness created among large sections of citizens about the need to restore and preserve the water bodies in the city. Among the many water bodies that were identified to be in need of a major makeover was the Buckingham Canal. Several discussions, research and…
