It has been a part of Government's Science and Technology (S&T) policy toencourage the students/youth of the country towards the field of science and technology.
The first three key elements of Science, Technology, and Innovation (STI) Policy of 2013
Government is implementing several schemes to encourage students/youth of the countrytowards the field of science and technology. The "Innovation in Science Pursuit for InspiredResearch (INSPIRE)" is a major scheme in operation to attract, motivate, nurture and traintalented and meritorious students to study science subjects and opt for careers in Research andDevelopment (R&D) to build a pipeline of quality manpower, thereby widening the R&Dmanpower base of the country. Close to 42,000 young students of class 6th - 10th receivethe INSPIRE Award MANAK (Million Minds Augmenting National Aspiration and Knowledge)per year from all recognized schools across the country. About 20,000 students/year attend INSPIRE Internship Camps to experience the joys of creative pursuit of science. About 10,000students in top 1% of Class 12th Board examinations receive Scholarships For Higher Education (SHE) every year to pursue B.Sc and M.Sc courses in Basic and NaturalSciences. Every year, about 1,000 students are availing INSPIRE Fellowships for pursuingPh.D. degree. 100 young researchers/year are availing INSPIRE Faculty Fellowships toestablish themselves as independent post-doctoral researchers. In order to attract andmotivate young students, several international programmes are also being implemented bythe Department of Science and Technology (DST) such as Lindau meeting with NobelLaureates, Asian Science Camps, Raman Charpak Fellowships, Sakura Exchange programme,etc.
Autonomous institutions in the DST family also train large number of summerresearch interns, Ph.D. and post-doctoral fellows, organize large number of importantnational/international conferences, outreach programmes for school and college students including lectures by their scientists, orientation programmes etc.
The Science and Engineering Research Board (SERB), a statutory body of DST supports young researchers in a big way, through early career grants, core research grants, doctoraland postdoctoral fellowships etc. Some of the notable programmes targeted at youngscientists include: National Postdoctoral Fellowship (N-PDF), Start-up Research Grant(SRG), the Prime Minister's Fellowship for Doctoral Research, Swarnajayanti Fellowships etc.
These schemes are designed to identify promising young researchers and provide them with training and research opportunities in frontier areas of science and engineering. Close to 250 young researchers receive National Postdoctoral Fellowships annually. Majority of the 500 scientists supported under the Start-up Research Grant have been budding young researchers who take up high-end R&D in the country. There are 100 slots of fellowships available annually to researchers to pursue Ph.D.in partnership with Industry under the PM Fellowship for Doctoral Research.
The Council of Scientific and Industrial Research (CSIR) has been providingdoctoral and postdoctoral fellowships to young and budding researchers through its variousfellowship programmes such as Junior Research Fellowship ?National Eligibility Test (JRFNET),Shyama Prasad Mukherjee Fellowship (SPMF), Senior Research Fellowship (SRFDirect),Research Associateships and CSIR-Nehru Science Postdoctoral Research.
Fellowship (CSIR-NSPDF). Annually, CSIR offers about 4500-5000 such fellowships to youngstudents who are going to be future scientists. At any given time, CSIR supports about about8000-9000 young researchers in their pursuit for doctoral and postdoctoral research in the fieldof science and technology.
The Department of Biotechnology (DBT) has implemented integrated HumanResource Development Programme in Biotechnology including Star College Scheme forstrengthening of Undergraduate Science Education, Postgraduate Teaching Programme,
DBT-Junior Research Fellowship Programme, DBT-Research Associateship and DBTBiotechnologyIndustry Training (Apprenticeship) Programme in areas of Biotechnology andLife Sciences.
Government has taken several steps to promote affordable sustainable innovations in the field of science and technology. DST initiated a new program in 2016 called Promoting andAccelerating Young and Aspiring technology entrepreneurs (PRAYAS) under National Initiativefor Developing and Harnessing Innovations (NIDHI) with the objective to support conversion ofan innovative idea into a working prototype developed by any innovator. This programmeis aimed to attract large number of young innovators who demonstrate problem-solving zealand abilities and also to enhance the pipeline in terms of quality and number of innovativestartups to the incubators. This will build a vibrant innovation ecosystem, by establishinga network of innovators, academia, mentors and incubators.
For promoting affordable sustainable innovation in the field of science andtechnology, the National Innovation Foundation (NIF), an autonomous institution underDST organizes a biennial National Grassroots Innovation and Outstanding Traditional Knowledge Awards and for it, common people (including youth) share their ideas andinnovations. NIF provides value-addition and incubation support to the innovators so that theirtechnologies can reach the market. NIF has also set up NIF Incubation and EntrepreneurshipCouncil (NIFientreC), a Technology Business Incubator, for setting up and incubatingcommercial ventures based on innovative technologies of common people of the country.

Children with imaginative minds can come up with innovative solutions to problems in and around them.Government efforts are triggering this imagination and broadening the base of the pyramid of innovation that encourages children to come up with solutions for day to day problems based on science and technology. Such ideas are being solicited by the Department of Science and Technology (DST), and meritorious ideas are rewarded with the award money of Rs 10,000 with option of showcasing it to district, state, and national level exhibition along with mentoring support.
Lakhs of children from remotest parts of India are coming up with innovative solutions for problems they encounter - be they be safe kitchen devices, sustainable bio-toilets, or waste management solutions.
The Million Minds Augmenting National Aspirations and Knowledge (MANAK) programme was launched by the Department of Science and Technology (DST) in partnership with the National Innovation Foundation (NIF) in 2017. It emphasises on the power of ideas in young minds to create a pipeline of innovative students who can recognise problems and find solutions to them.
Aiming to harness the power of bright minds spread across 6 lakhs school in the country, DST invites students from government and private schools to send original and innovative ideas having potential to solve common problems.
These ideas go through a tough screening and mentoring process at the school level, district, and state level to be selected for the National level competitions.
Some very bright ideas often come from the remotest of places. Last year an award-winning submission was by Sulochana Kakodiya, a class 8 student from Govt. MS (Girls) Ashram Bichhua in Chhindwara, District in Madhya Pradesh. Realizing that people suffered health-related issues due to unhygienic manual cleaning of toilets, she came up with an idea of developing an automatic toilet cleaning machine. The brushes for cleaning the toilet are fixed inside the toilet itself, and they can automatically clean the toilet by rotating them.
A personal problem triggered the innovative spark in Sayan Akhtar Shaik, a class 9th student of Government Senior Secondary School, Neil Island of South Andaman. His mother suffered a cut in her finger while she was trying to open the plastic cap by pulling the nylon thread, which is attached with the LPG cylinder. To resolve this problem, encountered in most households once and for all, he developed a plastic (safety) cap opener of LPG cylinder.
More than 3.8 lakh students from all States and Union Territories of the country have submitted their ideas in 2019, and the number is increasing every year. Out of these, a few are provided with financial support of Rs 10,000 each for developing prototypes. After a series of DLEPC (District Level Exhibition and Project Competition) and subsequent SLEPC (State Level Exhibition and Project Competition), some of them are selected to exhibit their ideas at a national level competition.
This year online nominations for 2020-21 have resumed from 1st June 2020. Since students are not able to attend schools due to COVID 19, DST has encouraged them to use this time for generation of innovative ideas which can be submitted to the online portal www.inspireawards-dst.gov.in.As India rises rapidly in the global innovation index, government efforts are rapidly promoting a culture of innovation among young people who are daring to experiment with their ideas. The movement that has been sparked is fast spreading to the remote parts of India?s with dreams for a bright future for the country.

A group of scientists in India is working on genomic sequences of SARS-CoV-2 around the World, including India, to identify genetic variability and potential molecular targets in virus and human to find the best possible answer to combat the COVID 19 virus.
Breaking down the novel coronavirus challenge into many pieces to get to its root and see it from multiple directions, Dr. IndrajitSaha, Assistant Professor in the Department of Computer Science and Engineering of National Institute of Technical Teachers' Training and Research, Kolkata and his team have developed a web-based COVID- Predictor to predict the sequence of viruses online on the basis of machine learning and analysed 566 Indian SARS-CoV-2 genomes to find the genetic variability in terms of point mutation and Single Nucleotide Polymorphism (SNP).
The study being sponsored by Science and Engineering Research Board (SERB), a statutory body under the Department of Science and Technology (DST), has been published in the Journal called Infection, Genetics, and Evolution. They have mainly found that 57 out of 64 SNPs are present in 6 coding regions of Indian SARS-CoV-2 genomes, and all are nonsynonymous in nature.
They have extended this research for more than 10 thousand sequences around the globe, including India and found 20260, 18997, and 3514 unique mutation points globally, including India, excluding India and only for India, respectively.
The scientists are on the track to identify the genetic variability in SARS-CoV-2 genomes around the globe including India, find the number of virus strains using Single Nucleotide Polymorphism (SNP), spot the potential target proteins of the virus and human host based on Protein-Protein Interactions. They also carried out integrating the knowledge of genetic variability, recognise candidates of synthetic vaccine based on conserved genomic regions that is highly immunogenic and antigenic and detect the virus miRNAs that are also involved in regulating human mRNA.
They have computed the mutation similarity in sequences of different countries. The results show that the USA, England, and India are the top three countries having the geometric mean, 3.27%, 3.59%, and 5.39%, respectively, of mutation similarity score with other 72 countries. The scientists have also developed a web application for searching the mutation points in SARS-CoV-2 genomes globally and country wise. Besides, they are now working more towards protein-protein interactions, epitopes discovery, and virus miRNA prediction.

As the world runs out of fossil fuels and looks out for alternate sources of clean energy, there is good news from the Krishna-Godavari (KG) basin. The methane hydrate deposit in this basin is a rich source that will ensure adequate supplies of methane, a natural gas.
Methane is a clean and economical fuel. It is estimated that one cubic meter of methane hydrate contains 160-180 cubic meters of methane. Even the lowest estimate of methane present in the methane hydrates in KG Basin is twice that of all fossil fuel reserves available worldwide.
In a recent study conducted by researchers at the Agharkar Research Institute (ARI), an autonomous institute of the Department of Science and Technology, Govt. of India have found that the methane hydrate deposits are located in the Krishna-Godavari (KG) basin are of biogenic origin. The study was conducted as a part of the DST-SERB young scientist project titled 'Elucidating the community structure of methanogenic archaea in methane hydrate'. Methane hydrate is formed when hydrogen-bonded water and methane gas come into contact at high pressures and low temperatures in oceans.
According to the present study accepted for publishing in the journal 'Marine genomics', the ARI team has further identified the methanogens that produced the biogenic methane trapped as methane hydrate, which can be a significant source of energy.
"The massive methane hydrate deposits of biogenic origin in the Krishna-Godavari (KG) basin and near the coast of Andaman and Mahanadi make it necessary to study the associated methanogenic community," said Dr. Vikram B Lanjekar, the Principal Investigator of the study.
According to the ARI team, until recently, there have been only a few investigations of the methanogenic communities associated with methane hydrate-bearing sediments. This study has shown that methanogens under these elevated pressure and temperature conditions are well adapted to these conditions and are different in methane-producing activities. Understanding of these methane-producing methanogenic communities under such an extreme and pristine environment was very important. This study using molecular and culturing techniques revealed maximum methanogenic diversity in the KG basin, which is one of the prominent reasons to confirm it to be the extreme source of biogenic methane in comparison to the Andaman and Mahanadi basins.
The kinetics study based on their model also predicted the rate of biogenic methane generation in KG Basin hydrates to be 0.031 millimoles methane/gTOC/Day, resulting in total deposits of methane around 0.56 to 7.68trillion cubic feet (TCF). The sediment samples associated with methane hydrate deposits from Krishna Godawari, Andaman, and Mahanadi basin were provided by National Gas Hydrate Core Repository, GHRTC, ONGC, Panvel, Maharashtra for this study.
The ARI team has documented a predominance of genus Methanosarcina in KG basin, followed by a few other genera Methanoculleus, Methanobacterium. Genus Methanosarcina was found to be more diverse among the obtained genera with four different species M. siciliae, M. barkeri, M. flavescens, and M. mazeias per their findings.
"Cultivation, isolation, and characterization of putative novel Methanoculleus sp. nov. and Methanosarcinaspnov. from methane hydrate sediments of Krishna Godavari basin, India are reported for first time," said Dr. Vikram B Lanjekar, Principle Investigator of the study.

Lung cancer, the most common cause of cancer-related death worldwide, is tough to detect at early stages, making it difficult to treat. Scientists may soon have a solution in the form of diagnostic therapy for lung cancer which paves the way for personalized medicine.
Recently researchers from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute under the Department of Science & Technology (DST), Govt. of India, have developed a theranostics (diagnostic therapy) drug candidate for lung cancer. The research work funded jointly by DST, BRICS Multilateral R&D Projects grant, and SwarnaJayanti Fellowship Grant was published in the journal Theranostics.
The selective recognition and imaging of oncogene specific non-canonical DNA secondary structures (G-quadruplex-GQ structures) holds great promise in the development of diagnostic therapy (theranostics) for cancer and has been challenging due to their structural dynamics and diversity.
Prof. T. Govindaraju, along with his team from JNCASR, developed a small molecule for selective recognition of BCL-2 GQ through unique hybrid loop stacking and groove binding mode with turn on far-red fluorescence response and anticancer activity demonstrating the potential as GQ-targeted lung cancer theranostics.
The JNCASR team reported the theranostic activity of TGP18 molecule by turn on fluorescence recognition of BCL-2 GQ through unique hybrid binding mode as well as its anti-lung cancer activity and tissue imaging potential. Their strategy of specific topology recognition through hybrid binding mode led to capitalize on the gains of oxidative stress and genome instability to kill lung cancer cells in vivo. In addition, TGP18 with turn on emission band at the lower edge of far-red to NIR spectroscopic window proved to be a viable probe for tumour tissue imaging. Collectively, theranostic agent TGP18 with outstanding biocompatibility showed in vivo tumor inhibition and tissue imaging, indicating excellent clinical translational potential.
G-quadruplexes (GQs) are non-canonical DNA secondary structures which regulate a wide range of cellular processes, including expression of several oncogenes. In cancer cells, stabilization of GQs leads to replication stress and DNA damage accumulation and therefore considered as promising chemotherapeutic target. Despite the significant attempts to combine therapeutic and diagnostic properties in a single formulation, there are no concerted reports on small molecule theranostics. Similarly, there are no molecules reported for the topology selective recognition of myriad of GQs, especially oncogenic GQs.
This study by the JNCASR team revealed that the selective recognition originating from the distinct loop structure of GQ that alters the overall probe interaction and binding affinity. TGP18 binding to anti-apoptotic BCL-2 GQ ablates the pro-survival function and elicit anti-cancer activity by inducing death in cancer cells. The JNCASR team deciphered that inhibition of BCL-2 transcription synergized with signalling cascade of nucleolar stress, DNA damage, and oxidative stress in triggering apoptosis signalling pathway. Intervention of GQ mediated lethality by TGP18 translated into anti-cancer activity in both in vitro 3D spheroid culture and in vivo xenograft models of lung and breast cancer with superior efficacy for the former. In vivo therapeutic efficacy, supplemented with tumor 3D spheroid and tissue imaging potential define the role of TGP18 in GQ-targeted cancer theranostics.
According to their findings, a remarkably lower dosage of TGP18 (0.5 mg/kg) showed anti-lung tumor activity similar to anticancer drug gemcitabine at a very high dose of 100 mg/kg. The therapeutic agent TGP18 was found to reach the target tumor site as monitored by its far-red imaging of the tumor tissue.
This methodology can be further exploited to develop cancer-type specific theranostic drugs with tremendous implications in personalized medicine. A patent application has been already filed for this invention.

Infectious secretions from contagious diseases such as COVID 19, tuberculosis (TB), and influenza poses high risk for healthcare workers. Their exposure to the high-risk hazard while handling the waste can soon be controlled with a canister bag that solidifies the secretions rapidly, making disposal safer.
For the safe management of infected respiratory secretions, the researchers at Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), an autonomous institute under the Department of Science and Technology, Govt of India, have come up with a method for safe handling and disposal of respiratory secretions in hospitals for ICU patients or those with copious respiratory secretions treated in the wards. They have developed canister bags lined with super-absorbent material containing an effective disinfectant, named "AcryloSorb".
When the patient is admitted to the hospital, secretions are sucked into bottles or canisters using vacuum line and discarded through the waste fluid disposal system after subjecting to decontamination process. There is a high risk of contamination during the handling, and the disposal needs well-equipped sluice rooms with disinfection facilities. The safety threat and manpower issues will be manifold in less equipped hospitals or temporary isolation wards set up during pandemics.
The canister bags can absorb 500 ml of secretions and solidify it immediately. In addition to that, the whole system will be decontaminated within no time because of the presence of disinfectant. The liner structure has a patented design which allows the progressive absorbent availability upwards. Solidification and immediate disinfection that occurs inside these bags eliminate risk of secondary infections by avoiding spilling and aerosol formation, and thereby protect healthcare workers and promote safe workplace management.Canister bags are enclosed in a customizable sealer bag which can pack it as spill-proof decontaminated biomedical waste disposable through incineration. The product has been tested as per the international standards.
The SCTIMST team that realized this technology consists of biomaterial scientists and clinicians - Dr. Manju, S., Dr. ManojKomath, Dr. Asha Kishore, Dr. Ajay Prasad Hrishi. The know-how of the AcryloSorb suction canister liner (CL Series) bags has been transferred to Romsons Scientific and Surgical Pvt. Ltd for manufacture and immediate marketing. The approximate cost will be Rs. 100/- for each canister liner bag.
Romsons Scientific & Surgical Pvt. Ltd, located at Uttar Pradesh, is a global player in medical devices with more than 200 products in market. The company has proven expertise of half a century in the area of disposable medical and surgical devices and is a prominent brand in the medical device community. The company has its distribution channel across 65 countries. Quality is a prime motto of Romsons, evidenced by the ISO and CE certifications for many of their products.
The field trials of the in-house designed suction canister liner bags are being conducted in SCTIMST.

Scientists have developed a portable sterilisation unit using a new technology called the hybrid sterilization system that can decontaminate personal protective equipment (PPE) necessary for combating COVID 19, easily and rapidly, allowing them to be used multiple times.
It can be used by health professionals and other COVID warriors for whom PPEs are essential and can prevent generation of hazardous solid waste from PPEs.
IIT Tirupati (IITT) and IISER Tirupati have jointly developed the Portable Optical Cavity.
Sterilization Unit (POSCU) to provide efficient and rapid decontamination of personal protective equipment (PPE) and other household items. A working point-of-use sterilization unit has been developed with the support of Science and Engineering Research Board (SERB), a statutory body under the Department of Science and Technology (DST).
UV radiation is a proven method for sterilization. However, the lower penetration depth of UV-C and faster divergence from the source can result in nonuniform treatment. The team consisting of Dr. Reetesh Kumar Gangwar (Asst. Prof., Physics), Dr. Arijit Sharma (Asst. Prof., Physics), and Dr. Shihabudheen M. Maliyekkal (Asst. Prof., Civil & Environmental Engineering) from IITT have developed this hybrid sterilization system consisting of a UV radiation cavity, cold plasma, and H2O2 spray.
Unlike the traditional UV systems, this unit follows the optical cavity concept to optimize the use of photon flux in the treatment area. The system confines the UV radiation and enhances photon-flux and sterilization efficacy. The coherent operation of UV-C, cold plasma, and H2O2 spray further strengthens the sterilization efficiency due to more hydroxyl radical production.
Dr. VasudharaniDevanathan from IISER Tirupati will assist the IITT team in evaluating the sterilizing efficiency of the portable unit. Dr. R. Jyaprada (MD Microbiology), SVIMS hospital, Tirupati, will also test the system's effectiveness in the SVIMS microbiology laboratory.
The team is currently optimizing the design parameters, including UV dose, plasma, and H2O2 concentration, to get the optimum sterilization performance in short contact time of less than 2 min. Due to the non-thermal nature of the treatment, the proposed unit shall also find application in the sterilization of other items such as packed and unpacked food, currency, and other household items.
