Pierre-Simon Laplace, an exemplary French Mathematician, once quoted: “It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit.

I intentionally aimed to start this article with a quote by an excellent western mathematician, because we Indians need validation from westerners. We are quite capable of making high strides in science, technology, and innovation, but there is a lack of vision; lack of confidence.

The newly Independent India of 1947 had a vision: a vision to transform into a developed country using scientific interventions. We had some great revolutionaries who worked tirelessly to shape a bright future for our country. Dr. Vikaram Sarabhai founded the Indian Space Research Organization (ISRO) while Dr. Homi J Bhabha, the Department of Atomic Energy (DAE). There was a time when Dr Sarabhai convinced a Church to give land for a rocket launch station.

When India became Independent in 1947, people just wanted to earn enough to survive in the rapidly changing, bitter conditions. Today, when we are one of the economies of the world, we are fighting over temples and mosques, trying to rename cities, and dream of resurrecting some thousands of years old notion of India, the quest for scientific temperament is lost somewhere along the way.

Over the years, India’s spending on Research and Development has increased significantly in overall value but its share in GDP has remained stagnant at 0.6-0.9%. The research being done in India is quite good if we compare it to the funding received. However if we compare it with the developed countries, the gap is phenomenal.

India’s space program, atomic energy program, development of supercomputers, or development of light combat aircraft- Tejas shows that Indian scientists have given great results at a fraction of the costs of their western counterparts. Still the allocation of funds for the scientific research is well short of what is required to catapult India into the league of developed nations.

If we deep dive into the probable causes of underfunding of Indian scientific research in spite of giving good return on investment, it boils down to the lack of awareness about the same among the larger public as well as policymakers. As we know that the best way to receive funding is to create awareness about a valuable product. We don’t lack products; we lack dialogue. Science is hardly ever reported in India. It’s rarely a point of discourse. When there is no discourse around something, it leads to a lack of interest. This is also driving away the bright students from pure sciences to the technology and management which is more remunerative.  

Another issue that sprouts up from lack of discourse is the lack of belief in science. We have seen how in India, many public figures started spreading home remedies and terrible unchecked solutions like the benefits of Cow Urine during the COVID outbreak. The news channels, instead of discussing facts, talked about conspiracy theories. These news channels sometimes invited scientists for talks, but eventually, ruined everyone’s time for their TRP by asking them about the conspiracy theories.

Science literacy can reduce these pseudoscience tactics. Indians extensively believe in spirituality which is good for personal motivation and values, however the unscrupulous elements have often used it to spread misinformation and personal gains. It's imperative that we take a stand to promote scientific thought, and this is not at all an arduous task. Instead, the solution is straightforward: We need to communicate.

We need our own Neil DeGrasse Tysons, Carl Zimmers, Carl Sagans who can communicate with the common people about scientific development, in a simple language. This will help us to kick start our journey towards the Golden Era of Science without a baggage of baseless beliefs, pseudoscience, and untested products.

Xenobots: The first ever ‘living’ robots

Creating robots using artificial intelligence has become quite normal in this century. But a robot built with an amalgamation of artificial intelligence and biology is quite enthralling. Researchers from University of Vermont and Tufts University collaborated to conceive a living robot called ‘Xenobot’.

This astounding, millimeter-wide chunk of technology is considered to be ‘living’ as it is created by stem cells from the embryo of Xenopus laevis, an African frog species. These stem cells were selected in such a way that they grew out to be heart and skin cells.

Prior to this, computer scientists at the University of Vermont ran an evolutionary algorithm, which imitates natural selection, on their supercomputer, which yielded the most suitable structures of the robot. After selecting the best designs, biologists at the Tufts University moulded the skin and heart cells into the forms which closely resembled the outputs of the algorithm, through microsurgery.

The resulting biological bodies looked like tiny aliens. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism" said Joshua Bongard, a computer scientist and robotics expert at the University of Vermont, who was involved in the research. Detailed results are published in the Proceedings of the National Academy of Sciences (PNAS) research paper on January 13, 2020.

Newly created xenobots were found to swim in any liquid medium for at least 10 days (or more if put in a nutrient-rich environment) without being fed with any nourishment, since the cells have a reserve of embryonic energy.

Another incredible facet of this technology is that it can revamp any of its parts efficiently upon damage. While technological pieces made out of plastic and metal might cause a lot of pollution after they are disposed of, xenobots are completely biodegradable, causing no harm to the environment. "These xenobots are fully biodegradable, when they're done with their job after seven days, they're just dead skin cells" said Bongard.

One might wonder how these miniscule cell blotches are helpful to us. Well, Xenobots may be very small in size but they can achieve feats which almost no huge, metal-made robot can.

These living robots will be useful in certain fields like medicine wherein they could be utilized to clear plague from our arteries. They can also be modelled with pouches which enables them to carry certain substances. This property can be used for delivering drugs in specific parts of our bodies. Xenobots can also be a boon in the field of cancer biology as they can help reprogramming tumors into normal cells.

Additionally, these tiny biological bodies can be oceans’ best friends. With contaminants like radioactive chemicals, plastics and microplastics creating havoc in the marine world, an immediate need to clean up our water bodies arises. Many xenobots were observed to be moving in circles (an attribute of the beating heart cells), which resembled a ‘clean-up’ motion. Hence, these tiny robots can be a perfect tool to eradicate microplastics from the oceans as well as eliminating nuclear wastes.

Although this technology may be promising, certain ethical questions arise with every technological development, especially those involving biological manipulations. If programmed in a certain way, xenobots can also take over natural biological functions (maybe nerve cells to hamper brain function) and this can be used for nasty purposes.

Michael Levin who directs the Center for Regenerative and Developmental Biology at Tufts said, “That fear is not unreasonable. When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences”. Levin and Bongard are extensively working towards understanding how complex systems work. "There's all of this innate creativity in life. We want to understand that more deeply—and how we can direct and push it toward new forms" said UVM's Josh Bongard.

Like any new disruptive technological innovation, the Xenobots also have the potential to prove boon or bane for the humankind. Let's hope it turns out more boon than bane.
