Talking about facts, there are 13% of inhabitants in Delhi who do not get water supply every day. If India’s national capital is dealing with such water crisis, think how acute the problem is in the rural areas.
Millions of people are still compelled to drink contaminated water leading to a series of health issues. In rural India, thousands of infants die each year only due to diarrheal diseases, which are both preventable and treatable. According to World Health Organization (WHO), diarrheal diseases are the second leading cause of death in children under five years old.
The problem is so critical that even if we achieve the Millennium Development Goal of halving the population who do not have access to drinking water and sanitation by 2015, there will still be 244 million people in rural India and 90 million in urban India with no access to safe and sustainable water supply.
Keeping in mind the high cost of water purifiers available in the market and unavailability of electricity in rural areas, Nimbkar Agricultural Research Institute (NARI), an NGO working in rural Maharashtra, has developed a unique and low cost solar water purifier (SWP) for rural households. The best part is that it does not even require electricity or wastes precious water unlike the Reverse Osmosis (RO) systems.
“We live in rural area and we have observed that because of poor drinking water there are a lot of diarrhea related health issues. More so with children and so we thought of providing a solution to it and hence the solar water purifier,” added Rajvanshi.
The low cost water purifier consists of four tubular solar water heaters attached to a stainless steel manifold. Unclean water is then filled in SWP after being filtered with a four-layered cotton cloth and then it is heated up in the stagnation mode by solar energy to make the water potable.
How it works?
SWP was developed in two steps essentially. The first step required a four-layered cotton sari cloth to filter unclean water. NARI explained that the tests done in its labs showed that such filtered water heated either to 60C for 15 minutes or 45C for 3 hours suspends all the coliform bacteria.
SWP has been tested extensively by NARI and it was found that even on a completely cloudy and rainy day, water is heated to high enough temperature to make water clean and drinkable.
The main goal of NARI was to create a water purifier that could be easily afforded by the rural inhabitants.
SWP costs about Rs. 1,500 ($25), and is so simple that any small rural workshop can manufacture it.
The fact that should be highly appreciated is that NARI has not patented this technology since it believes that the purifier should be made freely available for rural population.
“I have always believed that availability of clean drinking water to every citizen is a birth right and every government of the day should provide it. You may be able to live without food for 5-10 days but cannot live without water for more than 5 hours. Clean drinking water is extremely important for health. The difference between poverty and affluence is the availability of clean drinking water,” said Rajvanshi.
Bollywood actor Abhishek Bachchan shares how he feels when people compare him with his father Amitabh Bachchan on the singing reality show 'Sa Re Ga Ma Pa'. He also requests contestant Rajshree Bag to sing a track 'Bahon Mein Chale Aao' featuring his mother Jaya Bachchan.
Abhishek said after looking at the performance of Rajshree, who is often compared with Lata Mangeshkar on the show, that she reminds him of being compared with his father. "Rajshree, whenever I have got the chance to watch the show, I've seen people compare you to Lata didi. It actually reminded me about how people compare me with my father and ask me how I feel about it."
According to him Amitabh Bachchan is a great actor in the industry and this is what he says to everyone making these comparisons. "My answer to them is that there's no greater actor in this film industry than Amitabh Bachchan and if I'm being compared to him, I am sure I must have done something good."
"Similarly, your voice has a different kind of magic like Lata ji and that's why people are comparing your voice with her. I feel you should always take this as a compliment," he concluded. 'Sa Re Ga Ma Pa' airs on Saturday and Sunday on Zee TV. (IANS/ MBI)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
Celebrity chef, Sanjeev Kapoor, strongly advocates this need of eating seasonal produce. He says, "The beauty of our food is in our seasonal usage of fruits and vegetables. If you realise, Gajar ka halwa is made aplenty during winters as this is the season when beautiful red carrots hit the market or mango pickle is made during summer, thanks to its availability. Despite people and sometimes, even me, suggesting that we should eat fresh as well as seasonal fruits and vegetables, we do not know what chemicals are sprayed on them to keep them safe while they are growing. When this produce hits the market, there isn't a certifying agency like the FSSAI that will help people understand what vegetables and fruits are free of pesticides and germs and which ones don't. Hence, the onus lies on us to make them safe for consumption. ITC's Nimwash is a good solution."
When it comes to winters, the Chef recommends eating these fruit and vegetables:
* Purple Mogri -- Mogri or Radish pods are not a common sight throughout the country. But you can spot them during the winters in local markets in northern India where women pick them up to make raitas, curries and stir fries. Rich in magnesium, calcium and copper, the vegetable is known to aid people from digestive problems.

* Sweet Potato -- A re-discovered favourite, Sweet potatoes have created a space for itself in the millennial kitchen. With its diverse addition in burgers, chips and even chat, the root vegetable is filled with nutrients such as fibres and vitamins.

* Avarekalu -- Called Hyacinth beans in English, Avarekalu is a winter speciality in the south that is added to sambhar, saagu, rotis, etc. Bangalore is famed for its Averakalu mela during the winter months, where you can find these beans in dosas, Pani puri and even Jalebis! Thronged by crowds from all over the city, the food fest is a gourmand's delight.

* Amla -- The Indian gooseberry is a common winter fruit found through the country. High in Vitamin C, it is known to be immunity building and extremely beneficial for the skin and hair. There are multiple ways to eat Amla -- it is pickled, made into a fruit preserve called as Murraba or even eaten by sprinkling salt over it.

Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a new study. The study, published in the journal Scientific Reports, found there was, on average, a 17 per cent improvement in participants' colour contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week.
However, when the same test was conducted in the afternoon, no improvement was seen. "We demonstrate that one single exposure to long wave deep red light in the morning can significantly improve declining vision, which is a major health and wellbeing issue, affecting millions of people globally," said lead author, Glen Jeffery from the University College London.

For the study, the team involved a small yet significant number of participants aged between 34 and 70, had no ocular disease, completed a questionnaire regarding eye health prior to testing, and had normal colour vision (cone function). This was assessed using a 'Chroma Test' -- identifying coloured letters that had very low contrast and appeared increasingly blurred, a process called colour contrast.
Using a provided LED device, all participants were exposed to three minutes of 670nm deep red light in the morning between 8 a.m. and 9 a.m. Their colour vision was then tested again three hours post exposure and 10 of the participants were also tested one week post exposure. On average there was a 'significant' 17 per cent improvement in colour vision, which lasted a week in tested participants; in some older participants, there was a 20 per cent improvement, also lasting a week.
A few months on from the first test (ensuring any positive effects of the deep red light had been 'washed out') few participants, carried out the same test in the afternoon, between 12 p.m. to 1 p.m. When participants then had their colour vision tested again, it showed zero improvement.
