Akashteer air defence systems

• These are advanced Air Defence Control and Reporting Systems (ADCRS) which will serve as a critical asset in safeguarding the country from aerial threats, including missile and rocket attacks. 
• It is a sophisticated, integrated control and reporting system designed to neutralize enemy threats swiftly.
• The system is capable of managing all aspects of air defence for the Army, integrating multiple radar systems, sensors, and communication technologies into a single operational framework.
• It provides a real-time battlefield view, allowing military personnel to detect, track, and engage aerial threats such as incoming missiles or enemy aircraft.
• It brings together various surveillance assets, radar systems, and communication nodes, enabling precise coordination of air defence operations.
• It is suitable for a wide range of operational environments. 
• It is developed by Bharat Electronics Limited (BEL).

The Bureau of Indian Standards (BIS) has begun the process of formulating a National Agriculture Code (NAC), on the lines of the existing National Building Code and National Electrical Code. 
• It will cover the entire agriculture cycle, and will also contain a guidance note for future standardisation.
• The code will have two parts. The first will contain general principles for all crops, and the second will deal with crop-specific standards for the likes of paddy, wheat, oilseeds, and pulses.
• The NAC will serve as a guide for farmers, agriculture universities, and officials involved in the field.
• It will cover all agriculture processes and post-harvest operations, such as crop selection, land preparation, sowing/transplanting, irrigation/drainage, soil health management, plant health management, harvesting/threshing, primary processing, post-harvest, sustainability, and record maintenance.
• It will also include standards for input management, like use of chemical fertilisers, pesticides, and weedicides, as well as standards for crop storage and traceability.
• Crucially, the NAC will cover all new and emerging areas like natural farming and organic farming, as well as the use of Internet-of-Things in the field of agriculture.

In a recent study published in Nature Communications, physicists from Purdue University in the U.S. reported levitating Fluorescent Nano-Diamonds (FNDs) in a high vacuum and spinning them very fast, paving the way for multiple applications in industry.

• These are nanometre-sized diamonds made of carbon nanoparticles.

• Properties:-
• They are produced in a high temperature and high pressure process.
• FNDs are stable under light and aren’t toxic to living things.
• FNDs don’t blink when irradiated for a long time.
• Their fluorescence lifespan is greater than 10 nanoseconds (ns) — a relatively long duration — which makes them better than quantum dots.
• FNDs can also be doped to enhance their electrical, magnetic, thermal, and/or optical properties.
