Innovative Solar Technologies

What we decide to do today is bound to have an impact on our tomorrow. Therefore, it is up to us to determine the kind of world we want to develop for our future and leave behind for our next generation. We are already witnessing manifold consequences of rising global warming and climate change in the form of extreme weather events. Think about droughts, floods, forest fires, and many such catastrophes.

We all are aware that increasing carbon emissions are largely responsible for disturbing our climate...

The Time-Travel Telescope

The Time-Travel Telescope

We’ve all seen many science fiction movies about a time machine that allows us to rewind into the past and even fast-forward into the future. But we’ve all wondered if this would ever become a reality. Nonetheless, what if someone tells you that it is indeed possible! Would you believe it? If it helps the predicament, then one such claimant is NASA—the National Aeronautical Space Agency of the USA... 

Science through Turmeric and Detergents

Science through Turmeric and Detergents

One fine day, we woke up and found our city, country, whole wide world and everything else come to a standstill. Something absolutely unexpected, not even in the worst of our dreams, had happened. Then, suddenly, all the related challenges began hitting us.

There came in the role of a teacher. I have been a person who is not so tech-savvy and struggles to overcome her anxiety about going online. In fact, just as me, there were many teachers, mostly at the verge of retirement, who were trying their best to connect with their students. We were aware that life shouldn’t stop because of the lockdown and that the show must go on.

What Did the CSE Study on Honey Adulteration Reveal? Complete Analysis on How the Tests Were Done.

What is the truth behind India's honey? How pure is the honey made by your favourite brand? Are you eating nature's wonder food or are the companies selling you cheap and unhealthy sugar? To find these answers let us look at the latest report by the Delhi based Centre for Science and Environment or CSE.

CSE has earlier exposed pesticides in colas and packaged drinking water, antibiotics in honey, GMO's in packaged food, and excess salts and trans fat in junk foods...

Water Conservation vs Carry Water by Train, Which is Better?

Water Conservation vs Carry Water by Train, Which is Better?

Carrying water by trains could be an emergency measure. Chennai has a strong tradition of water harvesting. But the problem is that most of these structures are either defunct or poorly maintained. Chennai which had 19 major lakes covering an area of 1130 hectares. But these waterbodies have been heavily encroached upon reducing their spread to just about 645 hectares. Its time that we understand the importance of water harvesting.

A New Kind of Pollution: This Time in Our Food

A New Kind of Pollution: This Time in Our Food

Genetic engineering is used to modify the food we eat. But do we know enough about its effect on us?

For as long as we know, the food we eat is grown in farms and fields by farmers who sow seeds and harvest them every season. Adulterations in food products sold loose, such as pulses or sugar in the local kirana stores, is quite common.

But we never worry about adulterations while buying packaged food from the shelves of our favourite shop. After all, they pass through several quality checks. But a study by Delhi-based non-profit Centre for Science and Environment (CSE) has found that packaged food items have genetically modified (GM) ingredients in them.

Fruitful Journey: Food Safari in the Rajasthan Desert

Fruitful Journey: Food Safari in the Rajasthan Desert

Down To Earth travels to the desert state of Rajasthan to find out about the traditional food habits of the people in one of the driest regions of the country. We discovered that so many things grow in the wild and traditional knowledge of these will ensure that you have plenty to eat in the harsh desert environment. But is this traditional knowledge losing its ground slowly?.
