News on Science, Technology and Research in India
Indian researchers have developed a high performance industry-standard model for Aluminium gallium nitride (AlGaN/GaN) High Electron Mobility Transistors (HEMTs) with simple design procedures which can be used to make high-power Radio Frequency (RF) circuits owing to its high breakdown voltage.
19-year-old Jahnavi has today become the only Indian to undergo the International Air and Space Program at NASA Launch Operations’ Kennedy Space Centre in Alabama, US.
India will soon develop and manufacture receiver modules essential for the NavIC (NAVigation with Indian Constellation), an application developed by ISRO for constellation of seven satellites that, together, provide navigation support over India and 1,500 km around it. Support for scaling up this technology, which is also essential for GPS (Global Positioning Systems)s will be a significant step in positioning India as a global hub for Electronics System Design and Manufacturing following the vision of the Prime Minister.
Scientists have found the first clues to understand violent short duration flares from a compact star of rare category called magnetar located thirteen million light years away. These compact stars with the most intense magnetic field known, of which only thirty have been spotted so far in our galaxy, suffer violent eruptions that are still little known due to their unexpected nature and their short duration. Scientists have long been intrigued by such short and intence bursts — transient X-ray pulses of energies several times that of the Sun and length ranging from a fraction of a few millisecond to a few microseconds.
A study by a team of scientists led by Dr. Wageesh Mishra of the Indian Institute of Astrophysics (IIA), Bengaluru, an autonomous institute of the Department of Science & Technology, Government of India, has brought out some interesting insights.
Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh said, ISRO has signed six agreements with four countries for launching foreign satellitesduring 2021-2023.
The researchers used an amino acid called Tyrosine, which is present in many food items, including meat, dairy, nuts, and beans. They treated silver nitrate, the main component of the ‘election ink’ used to stain nails after voting in India, with tyrosine in the presence of caustic soda. Tyrosine functioned as a reducing agent and capping agent to produce silver nanomaterials.
Malaria biology is an interesting field not only from the perspective of biochemical or molecular investigations, but it also allows addressing exciting cell biology/organelle-biology questions. This intracellular parasite exhibits unique organellar complexity and divergence. It harbors a single mitochondrion which undergoes dramatic morphological changes, an apicoplast (non-photosynthetic, relict plastid), very dynamic endoplasmic reticulum, and lysosomes.
India will launch its first indigenously made space station by 2030, just a few years after the ‘Gaganyaan’ mission which will kick off starting 2022.
The study at IISER -Bhopal fills an important gap. Dr. Vineet K. Sharma, team leader and Associate Professor at the Institute’s Department of Biological Sciences, said their research work is particularly significant because turmeric has been the focus in more than 3,000 publications. But its whole genome sequence was not known so far.
