Threats to the Taj The once white marble of the Taj is slowly turning yellow and green due to several reasons. Pollution - Toxic air of the city and its neighbours are one of the biggest reasons for stripping the Taj of its beauty. India is home to some of the most polluted cities in the world, Agra being one of them. And being covered in smog and dust for most part is taking a toll on the Taj’s white marble. Everything from the smoke from vehicles, to the soot and fumes from factories and rampant construction around the area of the monument is adding up to the decline. Yamuna - The Yamuna river, on whose bank the ... Read More...

Coronaviruses are “large family of viruses that was first identified in humans in the mid-1960s”. While some of these viruses cause common cold, others “found in bats, camels and other animals can evolve into more severe illnesses” such as SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome). The virus gets its name from the Latin ‘corona’ (halo or crown) as it resembles one when viewed under a... Read More...

Sugarcane was the last major cultivated plant to have its genome sequenced. This was because of its huge complexity: the genome comprises between 10 and 12 copies of each chromosome, when the human genome has just two. It was an international team coordinated by CIRAD that achieved this milestone. CIRAD is a French Agricultural Research Centre for International Development and is working for the sustainable development of tropical and Mediterranean regions. It will now be possible to modernize the methods used to breed sugarcane varieties. This will be a real boon to the sugar and biomass industry. Sugarcane produces 80 p... Read More...

As India celebrates its 72nd Independence Day this year, India is a self-confident nation able to manage its external relations on its own terms. It can engage the United States as a strategic partner even as it can chart its own course vis-à-vis Russia and China. It can stand with China to raise its voice against global protectionism and yet it can stand up to China when its vital interests are targeted, like in Doklam last year. If there is one power that sits relatively confident in today’s rapidly evolving global dynamic when all other powers are openly competing with each other, it is India. Let there be no doubt about it. As India&r... Read More...

Most materials people use are insulators, like plastic, or conductors, like an aluminum pot or a copper cable. Insulators show very high resistance to electricity. Conductors like copper show some resistance. Another class of materials show no resistance at all when cooled to very low temperatures, cooler than the coolest deep freezer. Called superconductors, they were discovered in 1911. Today, they are revolutionizing the electric grid, cell phone technology and medical diagnosis. Scientists are working to make them perform at room temperature.Some of the technological applications of superconductivity include: 1. the production of sensitive magneto... Read More...

The draft National Energy Storage Mission seeks to set up grid-connected energy storage in India, set up a regulatory framework, and encourage indigenous manufacture of batteries. The draft sets a “realistic target” of 15-20 gigawatt hours (GWh) of grid-connected storage within the next five years Power grids do not currently use storage options that would help in smoothly integrating renewable energy sources. The mission will focus on seven verticals: indigenous manufacturing; an assessment of technology and cost trends; a policy and regulatory framework; financing, business models and market creation; research and development; standards ...

‘Convection clouds’ are ones that form and grow by the process known as convection. Cumulus and Cumulonimbus are examples of this type of cloud. Convection in the atmosphere is the way air floats upwards on account of being warmer than the surrounding air.  Our understanding of the monsoons has improved a lot in the past decades. We now understand clouds better, which has been revolutionised by satellites. In any model, knowledge of clouds is the most important. We need clouds for rain. Any problem in the prediction of rainfall is related to the prediction of clouds. The monsoon clouds here are convective. In the US, the weather doesn... Read More...
