Target Prelims 2025: Day 2
1. R21/Matrix-M Malaria Vaccine:
World Health Organisation (WHO) recommended 2nd new vaccine, R21/Matrix-M, for the prevention of malaria in children.
➢ 1st vaccine was RTS,S/AS01 vaccine, which received a WHO recommendation in 2021.
R21/Matrix-M vaccine has already been approved for use in Burkina Faso, Ghana, and Nigeria.
* Malaria is a mosquito-borne blood disease caused by plasmodium protozoa.
• The parasites spread through the bites of infected female Anopheles mosquitoes.
• In the human body, parasites initially multiply in liver cells and then attack the Red Blood Cells (RBCs).
** E-2025 Initiative – 25 countries has been identified to eradicate malaria by 2025 under this Initiative.
** High Burden to High Impact (HBHI) - Initiated in 11 high malaria burden countries, including India, to reignite the pace of progress in the global malaria fight.
2. Attosecond Pulses:
These are incredibly short bursts of light, lasting for just a billionth of a billionth of a second.
• These have allowed scientists to capture the fastest events ever recorded, with a time resolution on the order of attoseconds.
➢ It is a unit of time in the International System of Units (SI), which is equal to 1×10-18 of a second (one quintillionth of a second).
• These pulses are generated by a process called high harmonic generation, where intense laser pulses interact with a gas target to produce a broad spectrum of harmonics, including attosecond pulses.
These can have potential applications in , Ultrafast Electron Dynamics, Probing Materials, Controlling Electron Behavior etc.
* 2023 Nobel Prize foe physics as given for attosecond pulses.
3. Winter Diesel:
• India’s armed forces may soon be using winter diesel for operations in high altitude areas such as Ladakh.
• Winter diesel is a specialised fuel that was introduced by Indian Oil Corporation (IOC) last year specifically for high altitude regions and low-temperature regions such as Ladakh, where ordinary diesel can become unusable.
• It contains additives to maintain lower viscosity can be used in temperatures as low as -30°C and that besides a low pour point, it had higher cetane rating — an indicator is the combustion speed of diesel and compression needed for ignition— and lower sulphur content, which would lead to lower deposits in engines and better performance.
4. Global Partnership on Artificial Intelligence (GPAI):
• India joined GPAI or Gee-Pay as a founding member to support the responsible and human-centric development and use of AI.
• GPAI is an international and multi-stakeholder initiative to guide the responsible development and use of AI, grounded in human rights, inclusion, diversity, innovation, and economic growth.
• India joined the league of leading economies including USA, UK, EU, Australia, Canada, France, Germany, Italy, Japan, Mexico, New Zealand, Republic of Korea, Singapore to launch the GPAI.
• GPAI will be supported by a Secretariat, to be hosted by Organization for Economic Cooperation and Development (OECD) in Paris, as well as by two Centers of Expertise- one each in Montreal and Paris.
5. Indian National Space Promotion and Authorisation Centre (IN-SPACe):
• Government has announced a new organisation, IN-SPACe, part of reforms to increase private participation in the space sector.
• IN-SPACe will provide a level playing field for private companies to use Indian space infrastructure. This centre will also hand-hold, promote and guide the private industries in space activities through encouraging policies and a friendly regulatory environment.
• IN-SPACe is supposed to be a facilitator, and also a regulator. It will act as an interface between ISRO and private parties, and assess how best to utilise India’s space resources and increase
space-based activities.
