At Kerala Science Congress: Move to project nanotechnology as 'new alchemy'?

Dr BLV Prasad
By Rosamma Thomas 
In medieval chemical science, it was believed that base metals could be transformed to gold. For centuries, alchemists tried to transform lead to gold. It was telling that at the end of his lecture on the focus theme of nanotechnology at the 35th Kerala Science Congress at Kuttikkanam in Idukki district on Sunday, Dr BLV Prasad, Director, Centre for Nano and Soft Matter Sciences, Bangalore, showed a photograph of a jewellery shop, laden with gold – he mentioned that the image represented the desired goal for most industry linkages with nanotech.
‘Nanoscience and nanotechnology for human welfare’ was the focal theme of this Kerala Science Congress. Chief Minister Pinarayi Vijayan, inaugurating the conference, talked of how this congress will serve to bring together researchers in diverse fields, so they learn from each other and explore chances of collaboration.
The 2023-24 budget of the state government has allocated over Rs 3,000 crore for Research and Development, and the budget document states that Kerala is among the pioneering states in the country to “recognize the role of knowledge as a key resource of the modern economy.” CM Vijayan spoke of the light of knowledge, which would dispel superstition and notions of hierarchy based on caste, leading to a free society.
He cited Article 51A of the Constitution of India, and the duty to nurture the scientific temper and humanism. He mentioned that knowledge could not be confined within academic institutions, and must seep through society.
Over 700 delegates registered for the Science Congress event, where a range of scientific disciplines are represented – there are papers in agriculture, biotechnology, chemical sciences, earth and planetary sciences, engineering and technology, mathematics, nanotechnology, and environmental and health sciences to be presented at the event, which will conclude on February 14. 
The chief minister, in his inaugural address, also mentioned Hiroshima, Nagasaki and Vietnam, warning of the dangers of technology when used for violent ends.
The lecture hall was full to capacity and the cameras rolled during the inaugural session, at which the chief minister arrived punctually to make a pithy address. Once the chief minister left, however, the media personnel also appeared to follow him – the cameras were packed away, and the halls were no longer as full.
It was then that the series of inaugural lectures by scientists began – Dr BLV Prasad described his work and explained how his laboratory could be a site of research for scientists in other parts of the country. Following him, Dr Deepthy Menon of the Centre for Nanosciences and Molecular Medicine at the Amrita Vishwa Vidhyapeetam in Kochi spoke of the potential for nanotechnology in medicine – experiments are currently being conducted on mice and pigs, and some of them show remarkable recovery through delivery of drugs through nanotechnology.

One slide of a mouse with ovarian cancer showed successful treatment. Expounding on the potential for such delivery of drugs and devices, she mentioned “nano balls” which could encase “drug A, drug B, contrast agent A….” and aid in targeted delivery of the drug. Prof Sabu Thomas, vice chancellor of the Mahatma Gandhi University, Kottayam, who was chairing the session, asked about potential side-effects of the use of nanotechnology in human medicine.
“That’s a double-edged sword,” Dr Menon responded, admitting that if gold for instance were used in nanotechnology and injected into the human body, it would be necessary to check where the substance would accumulate.
In one of her slides, Dr Menon presented a list of the material that could be used in nanotechnology, and graphene, which could absorb radiation and thus prove harmful to human health, was among them.
She also presented another slide noting that there were over 6 lakh cancer deaths in the US in 2022; nearly 20 lakh new cases of cancer were detected in that country in just one year – the data did not include figures from previous years, so there was little the audience could do to glean cancer prevalence in the US over time. 
It was interesting that the point of reference for Dr Menon was the US, and her data was from the US; the authority she cited too was the Food and Drug Administration, US.
The nanotechnology lectures at the 35th Kerala Science Congress reminded this reporter of the warning that American astronomer and science writer Carl Sagan sounded in his final TV interview of May 27, 1996, warning that democracy would be at risk if the general population did not understand what the scientists were up to.

The golden crop: How turmeric is transforming women's lives in tribal India

By Vikas Meshram*   When the lush green fields of turmeric sway in the tribal belt of southern Rajasthan, Madhya Pradesh, and Gujarat, it is not merely a spice crop — it is the golden glow of self-reliance. In villages where even basic spices once had to be bought from the market, the very soil today is yielding a prosperity that has transformed the lives of thousands of families. At the heart of this transformation is the initiative of Vaagdhara, which has linked turmeric with livelihoods, nutrition, and village self-governance — gram swaraj.

Swami Vivekananda's views on caste and sexuality were 'painfully' regressive

By Bhaskar Sur* Swami Vivekananda now belongs more to the modern Hindu mythology than reality. It makes a daunting job to discover the real human being who knew unemployment, humiliation of losing a teaching job for 'incompetence', longed in vain for the bliss of a happy conjugal life only to suffer the consequent frustration.

Buddhist shrines were 'massively destroyed' by Brahmanical rulers: Historian DN Jha

Nalanda mahavihara By Rajiv Shah  Prominent historian DN Jha, an expert in India's ancient and medieval past, in his new book , "Against the Grain: Notes on Identity, Intolerance and History", in a sharp critique of "Hindutva ideologues", who look at the ancient period of Indian history as "a golden age marked by social harmony, devoid of any religious violence", has said, "Demolition and desecration of rival religious establishments, and the appropriation of their idols, was not uncommon in India before the advent of Islam".

Authoritarian destruction of the public sphere in Ecuador: Trumpism in action?

By Pilar Troya Fernández  The situation in Ecuador under Daniel Noboa's government is one of authoritarianism advancing on several fronts simultaneously to consolidate neoliberalism and total submission to the US international agenda. These are not isolated measures, but rather a coordinated strategy that combines job insecurity, the dismantling of the welfare state, unrestricted access to mining, the continuation of oil exploitation without environmental considerations, the centralization of power through the financial suffocation of local governments, and the systematic criminalization of all forms of opposition and popular organization.

Echoes of Vietnam and Chile: The devastating cost of the I-A Axis in Iran

​ By Ram Puniyani  ​The recent joint military actions by Israel and the United States against Iran have been devastating. Like all wars, this conflict is brutal to its core, leaving a trail of human suffering in its wake. The stated pretext for this aggression—the brutality of the Ayatollah Khamenei regime and its nuclear ambitions—clashes sharply with the reality of the diplomatic landscape. Iran had expressed a willingness to remain at the negotiating table, signaling a readiness to concede points emerging from dialogue. 

False claim? What Venezuela is witnessing is not surrender but a tactical retreat

By Manolo De Los Santos  The early morning hours of January 3, 2026, marked an inflection point in Venezuela and Latin America’s centuries-long struggle for self-determination and independence. Operation Absolute Resolve, ordered by the Trump administration, constituted the most brutal and direct military assault on a sovereign state in the region in recent memory. In a shocking operation that left hundreds dead, President Nicolás Maduro and First Lady Cilia Flores were illegally kidnapped from Venezuelan soil and transported to the United States, where they now face fabricated charges in a New York federal detention facility. In the two months since this act of war, a torrent of speculation has emerged from so-called experts and pundits across the political spectrum. This has followed three main lines: One . The operation’s success indicated treason at the highest levels of the Bolivarian Revolution. Two . Acting President Delcy Rodríguez and the remaining leadership have abandone...

The selective memory of a violent city: Uttam Nagar and the invisible victims of Delhi

By Sunil Kumar*  Hundreds of murders take place in Delhi every year, yet only a few incidents become topics of nationwide discussion. The question is: why does this happen? Today, the incident in Uttam Nagar has become the centre of national debate. A 26-year-old man, Tarun Kumar, was killed following a dispute that reportedly began after a balloon hit a small child. In several colonies of Delhi, slogans such as “Jai Shri Ram” and “Vande Mataram” are being raised while demanding the death penalty for Tarun’s killers. As a result, nearly 50,000 residents of Hastsal JJ Colony are now living in what resembles a state of confinement. 

The price of silence: Why Modi won’t follow Shastri, appeal for sacrifice

By Arundhati Dhuru, Sandeep Pandey*  ​In 1965, as India grappled with war and a crippling food crisis, Prime Minister Lal Bahadur Shastri faced a United States that used wheat shipments under the PL-480 agreement as a lever to dictate Indian foreign policy. Shastri’s response remains legendary: he appealed to the nation to skip one meal a day. Millions of middle-class households complied, choosing temporary hunger over the sacrifice of national dignity. Today, India faces a modern equivalent in the energy sector, yet the leadership’s response stands in stark contrast to that era of self-reliance.

Love letters in a lifelong war: Babusha Kohli’s resistance in verse

By Ravi Ranjan*  “War does not determine who is right—only who is left.” Bertrand Russell’s words echo hauntingly in our times, and few contemporary Hindi poets embody this truth as profoundly as Babusha Kohli. Emerging from Jabalpur, Madhya Pradesh, Kohli has carved a unique space in literature by weaving together tenderness, protest, and philosophy across poetry, prose, and cinema. Her work is not merely artistic expression—it is resistance, refuge, and a call for peace.
