- Silver Antimony Telluride Feb 2021: Bengaluru scientist discovered this new material it can facilitate "thermoelectric" energy conversion e.g. Using the heat from the laptop to charge the mobile phone. Using heat from the mobile phone to charge a small smart watch. Lead antimony telluride Has even more efficiency in this but it harms the environment, so silver better.
- What an Indian scientist created as a solution for his son’s asthma a few decades back has spawned itself into a new solution to tackle indoor pollution. Molekule’s PECO technology, based on Dr Yogi Goswami’s work in the US, has now been launched in India. while most companies try to capture the air and purify the particles in it, Molekule’s approach is to destroy, breaking down the chemical pollutants instead of physically capturing them - Photo Electrochemical Oxidation (PECO) technology
- Since ancient times, India has been at the forefront of science and technology. Charak and Susrutha in medical sciences, Aryabhata and Bhaskaracharya in mathematical sciences, Nagarjuna and Kanad in chemical sciences, to name a few, have done seminal work. The Indian Knowledge System (IKS) is full of such illustrious luminaries. The six schools of Indian philosophy, namely — Samkhya, Vaisheshika, Nyay, Yoga, Purva-Mimamsa, and Vedanta — have deep insights on logic, atomic theory, health, perception, inference, postulation, comparison, and deductions These dimensions are also the core components of modern science.
- Our institutes have done phenomenal research during testing times of the COVID-19 pandemic and have come up with testing kits, textiles, contact-tracing solutions and ventilator solutions. This shows that we respond well to challenges. The challenge posed every year to our young and dynamic students in the form of the Smart India Hackathon conducted by the Ministry of Education has seen massive participation. PM says India has 4Ds — Data, Demography, Demand and Democracy — to achieve world-class scientific solutions. To enable the demography to meet the demand this year, the Union budget has allocated a sum of Rs 50,000 crore to the National Research Foundation (NRF) proposed in NEP 2020. Also, the budget of the Ministry of Science and Technology has increased by 20 per cent
- Sindhu Sadhana -Research vessel, scientist from National Institute of Oceanography Panaji. It will collect samples of microorganisms from Indian ocean for genome mapping. It will help understand how microbes have adopted to different level of iron zinc cadmium, copper etc in various parts of ocean? → mining of polymetallic nodules.
- Pusa-FSF: Farm Sun Bridge - Solar powered refrigerator to store vegetables and prevent the post harvest losses by women scientists of Indian Agricultural Research Institute (IARI).
- Office of @PrinSciAdvGoI pays tribute to distinguished mathematician Padma Bhushan Prof. M S Narasimhan FRS. Famous for Narasimhan-Seshadri theorem, he made pioneering contributions to differential & algebraic geometry. He played key role in development of Mathematics in India.
- DuroKea = sanitizer / anti-bacterial product by IIT Hyderabad researchers. kills 99.99% of germs instantly. Leaves behind the long-lasting protective nanoscale coating up to 35 days
- Corbevax: new vaccine by Hyderabad-based company Biological E. Corbevax. Mechanism: “recombinant protein sub- unit made from SARS-CoV-2’s spike protein.” Similar method was used for creating hepatitis B vaccines. Indian government has placed advance order to buy 300 million doses. This is the first time government has placed advance order and before the vaccine is given approval.
- Zydus Cadila Ahmedabad company - Plasmid based vaccine - DNA molecule in bacteria having small number of genes of antibiotic resistance. Used in gene based vaccine(DNA needs mRNA while RNA directly - teach cell how to make protein that triggers immune response), Advantage - stable at higher temp, non infectious, stronger immunity, can be produced rapidly
- Indian researchers detect Gamma Ray Bursts(highly energetic due to black hole formation, mostly outside Milky way)
- Indrajaal - by Hyd based Grene company - autonomous defense weapon using AI, cybersecurity, robotics to counter UAVs, missiles as seen in June2021 drone use in JK
