Indian researchers make ”smart” contact lenses


Melbourne: A team of Indian research scientists are working on a device that can manipulate the extent of light and filter specific colors while still being transparent which can make up to “smart” contact lenses.

This research is being carried out by the scientists at Melbourne-based RMIT University and the University of Adelaide who are creating a stretchable nano-scale device to manipulate light.

These devices are made on a rubber like material which are used for contact lenses, said an associate professor Madhu Bhaskaran from RMIT.

“We embedded precisely-controlled crystals of titanium oxide – a material that is usually found in sunscreen, in these soft and pliable materials,” she said.

These materials form an ideal platform for wearable optical devices as these prove to be bio-compatible.

“By engineering the shape of these common materials, we can create a device that changes properties when stretched. This modifies the way the light interacts with and travels through the device, which holds promise of making smart contact lenses and stretchable colour changing surfaces,” Bhaskaran explained.

Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision.

In a more advanced version, the lenses can transmit data and gather live vital information or even show information like a head-up display.

“Manipulation of light using these artificial crystals uses precise engineering. With advanced techniques, we can dynamically control their filter properties, which allow us to create devices for high data-rate optical communication or smart contact lenses,” explained Dr Withawat Withayachumnankul from the University of Adelaide.

The current challenge is that dielectric resonators only work for specific colours, but with the new flexible surface, scientists can adjust the operation range simply by stretching it.

“With this technology, we now have the ability to develop light weight wearable optical components which also allow for the creation of futuristic devices like flexible smartphone cameras,” noted Gutruf in a paper published in the journal ACS Nano.(IANS)(

How advertisements in India are defying gender cliche

Ads playing an effective medium in moulding opinions of society

How Indian advertisement industry is breaking the gender stereotype

Feb 27, 2017: The most important part of advertisements is the story line and it gives a spur on the social media when the lessons from the story line are timeless. Needless to say, every time a free-spirited ad is released, it not only sparks conversations over the internet but also leaves a viral trail of debates. Just in the same way, some of the Indian advertisements did when they strove to change the mindset of people with regard to gender difference. We often tend to slur women not realizing the essence of being a woman, it takes strength and an indomitable spirit to be a woman. This article will talk about how advertisements in India are leading by example and discarding gender difference.

Let’s recall some of the advertisements that did away with gender difference.

Nike’s recent ‘Da Da Ding’ ad starring Deepika Padukone as one among other female athletes is a powerful ad which got the people talking about giving importance to female athletes as well. It showcased females of a real athletic figure which is not animated and has got nothing to do with ‘legs and butts’.

The ad portrayed women as fierce and passionate about sports. Once upon a time, Nike’s product catered almost exclusively to marathon runners and then, a fitness craze emerged –and the folks in Nike’s marketing department knew where to mark their next move, an applause for Nike for initiating a spellbinding effort.

Whisper, Touch the pickle ad

Whisper, Touch the pickle ad is another exemplary of breaking taboos surrounding women’s menstrual cycle. The whisper #Touchthepickle campaign makes an attempt to purge the baseless superstitions owing to Dos and Dont’s in menses. The ad showcases a young girl who dares to touch the pickle while she is on her periods. It conveys a sensible meaning to its viewers to break away these taboos. The ad was lauded internationally and awarded ‘Glass Lion Grand Prix’ award at Cannes International Festival of Creativity.

Many advertisements over the years have sold the cosmetic product but fewer have tried to change the societal conception of beauty. Even fewer have tried to do both, Joy Cosmetic is the brand that did it in India.

The ad begins with showcasing a well renowned oversized comedian, Bharti Singh asking the viewers “What did you expect, 36-24-36?”, and shuts down body shamers who presumed it to be an ideal body size. The ad conveys effortlessly that an Ideal beauty has nothing to do with body and shape.The advertisement has a sensitive message and is meaningful to its consumers.

Locating Desi: A Survey to establish Identity

Political mobilization of the word 'desi' in USA

Kerishma Panigrahi, a student of the New York University is pursuing studies in issues related to religion, race, racial subject formation mainly within the context of South Indian Diaspora. As part of her course, she is currently working on “Locating Latinidad“. The study includes tracing its history, genealogy and constitution as an identity. She has started a survey to know about the personal and political identification of people of South Asian descent in USA for folks who are 18 years or older.

You may take the survey here: Locating Desi

Kerishma says, “How I identify can shift as quickly and as easily as my surroundings shift; depending on where I am and who I’m with. I could be a Gujarati, Oriya, Indian(-American), South Asian(-American), American, desi, “brown”…the list goes on. What I became fascinated by was how intertwined and slippery racial, ethnic, and national identities are and how contingent they can be on one’s surroundings—which makes it even harder to effectively locate”.

What complicated her was the word ‘Desi’. According to her, it is a word which she can feel closer to and politically identify herself with it. With her experience from living among other South Asians in US, she feels that ‘desi’ is more of an informal and comfortable word as compared to South Asian-American. She is curious to know the experience of other folks of South Asian decent about the non-existent  political mobilization of the word ‘Desi’ compared to mobilization of ‘latinx’.

According to her, ” ‘Desi’ is also an imperfect term and there are shortcomings that may take away from people’s ability to identify with it; does “desi” have the ability to expand and accommodate this difference? Is there a disparity of identification along age group, migration status, country of origin, multiracial status? How does multiple diaspora (e.g. folks of Indo-Caribbean or Indo-African heritage) effect identification?”

Rediscovering – The tradition of Indian tattoos

Image Source- IndianRoots

by Annesha Das Gupta

Tattoos and the culture of India are the two things that many of us will immediately deem as an oxymoron. Through the electronic and the print media, the masses are feed upon the images that the art of tattooing as particularly a western phenomenon. Though, here the idiom of ‘What we see is not always true’ can be thoroughly applied.

Many of the customs and traditions of our subcontinent did become obsolete a long time ago, and the surprising bit is that the culture of tattoos is one of them. Tattoos were hold in ultimate veneration throughout the agrarian landscapes for much longer than what the annals of documentation tells us.

The ancient patterns of maze-like creations carved on the rocks dating back to the time of 1000 B.C. were later adopted by the tribal communities to mark their arms and other parts of their bodies. The patterns resembling a labyrinth known as Kolam, were often drawn by the families, residing in the regions of South India. The symbols were placed outside the threshold of their abodes, in order to protect the members of the household.

It was believed that the illustration is capable of magical powers which would trap the demons and other evil beings in the puzzle of the maze, something which cannot be solved by those creatures. The Kolam was usually made during the time of dawn, when as the legend goes, the inhabitants of the darkness come alive. Thus, it is of no wonder that the same was inked on the human bodies to permanently keep themselves safe and secure.

Apart from this one tattoo which was and still is believed to have magical properties, the marks, the symbols, the lines and the dots were regarded to borne medical, religious and sympathetic significance as well.

 Exploring the power of tattoos – Surreal and beyond

Gauitra Bahadur writes that while researching for her book Coolie Woman, she found out about the tradition of Sita Ki Rasio, a tattoo without which the married women of northeast India cannot cook meals for their in-laws. While another of the tattoos drawn on women, denotes the five Pandavas and one Draupati, as five dots centered around a single one. This can depict the harmonious relationship between various husbands as polygamy was readily practiced by some tribes like that of the Nagas.

Such instances, also tells us about the heavy influence of the Hindu epics such as Ramayana and Mahabharata. Then there is the symbol of Krishna’s crown which was wore by the Rajput women to show off their aristocracy indicating that the social status or position of someone’s caste or class can be read upon by the tattoo they have been marked with, like the caste of Govals who had the tattoos of Kanhaiyyaa and his milk maids inscribed on their arms.

The tattoos also used to work as something which will strengthen the marital relationship between the couples. The symbol of Moon or Chandi protecting his favorite wife, Rohini and the tattoos carrying the decorations of Vishnu’s tools like wheel and lotus are marked on the palms of the wives keeping with the terms of the legend that the God drew his weapons on the arms of his wife, Lakshmi to keep her secure while he was away, engaging in wars.

The craft of tattooing which is called Gudna in Hindu was mainly used to be done by the elders of the village or otherwise the itinerant women, who may be were illiterate but there was no standard of complex design that cannot be drawn by their expert hands and shrewd eyes. The Kothari women, who practiced tattooing on both men and women, generally began the task by restoring benediction on their subjects. The materials that were used in the exercise were three or more sharp needles tied up in a thread, organic materials like the coating of turmeric, cow’s milk and urine mixed with oil to lubricate and redeem the pain which will be felt by the person when the pricking will be going on.

Sometimes songs and nursery rhymes were also sung to divert and soothe away the pain which the man or the woman is going through. It is known that in the earlier times, no such distractions or ointments were applied and the area where the person has been tattooed would have been bloated and pain remained there for even more than a week.

Moving on, comes the religious powers that were believed to be donned by the tattoos, they also were said to have affinity to ease the work of everyday life. We can start on by the instance, where the horses and Hanuman being tattooed on the thighs of women so that they could be protected while walking barefoot and have the ability to labor all day in the field and carry out burdensome materials and task from one place to another.

The sector of agricultural, while, holds a primary place among the rural population and tribes and was therefore included it in the evolving structure of the tattoos. Especially when the harvesting season comes, the women who are not tattooed were not allowed to reap the crops and was considered to be impure for cultivation and its various purposes.

On the other hand, one can also speak of the medicinal importance of tattoos, like the ‘tattoo operations’ being performed to affect the remission of gout, rheumatism and arthritis.

Some of the tattoos are separately reserved to pay respect to motherhood like that the image of goddess Bara Deo, drawn on the breastbone of women, when their first infant is born. This particular part of the woman’s body is chosen due to the fact that it is where the child rests its head while been suspended inside the clothing. It is supposed to protect the child while the mother’s hands freely work in the fields.

Among the superstitious facets, it is held by some that tattooing can help them in keeping themselves secured, especially in their afterlife. As it is a common believe that the marked ones are safe as the devil do only devour the beings who are not tattooed and also that the inscriptions help the people to find their way safely back to their deceased ancestors.

It is also feared by some communities that if a man interrupts the tattooing ceremony by accident and markings on the body of the girl is not finished, no further performing of the task can be carried out. And that it is the will of the God, who will be shredding the woman’s body with iron rods after her death.

Concluding – The present state

We can make an appraisal of the current situation by Akhilesh Shukla’s report on tattoos of India at the Caravan Magazine which he titles as ‘Fading out’.

The traditional tattoo artists, he reports are at a total loss as the scope in this occupation has already gone its prime time and is now withering slowly away. Most of them, does not want their next generations to pursue the same path as the customs of the tattoos are getting erased from the minds, even of those who belong to the tribal communities.

In pre-Independent India, most of the tattoos used to cost a sum of one-sixth annas to that that of five and now it is more than that of hundred bucks even for a single line. Earlier, of course it was a fashion statement for the elites and also a necessity as the girls who do not have tattooed themselves before tying the knot, were considered as belonging to an uncultured background.

But now, the times have changed and so have the norms. Separating men from women, the male population, have also stopped getting themselves involved in the arena of tattoos as most of them, coming from the rural settings try out for the positions in the military. Since, there are already strict rules on any tattoos in the field many are discouraged to try their ‘hands’ out on this way.

Therefore, it may be safe to conclude that the future of traditional Indian tattoos, are rather degenerating into the pit-holes of loss of memory. Lack of proper anthropological research and dissemination of the topic is creating crevices which if not repaired soon, will become irretrievable.
