Current Affairs, 3 July 2026

Method used

The team used high-precision radiocarbon dating by Accelerator Mass Spectrometry (AMS) on extracted alpha-cellulose. Results were calibrated against IntCal20 and OxCal software.

Why not tree rings

Most tropical broadleaf trees lack distinct annual growth rings. This limits conventional dendrochronology and makes radiocarbon dating necessary.

Sampling site

Samples came from wood near the pith of a secondary trunk and an ancient primary branch. The pith holds the earliest wood formed in the juvenile stage of secondary growth.

Institute

Dr. Trina Bose of the Birbal Sahni Institute of Palaeosciences, Lucknow, led the work. The institute is an autonomous body under the Department of Science and Technology.

Radiocarbon basis

Radiocarbon dating measures the decay of carbon-14 in organic material. It suits material up to roughly 50,000 years old.

Don’t confuse with Dendrochronology vs radiocarbon dating: Dendrochronology counts annual growth rings, which most tropical broadleaf trees lack. Radiocarbon dating measures carbon-14 decay in wood and works without rings.

Don’t confuse with Carbon dating vs other isotope dating: Radiocarbon dating suits organic material of recent age, up to about 50,000 years. Uranium-series and potassium-argon methods are used for much older rocks and minerals.

Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.

Who chairs the DAC

The Defence Minister, Rajnath Singh, chaired the meeting.

What AoN means

AoN is an in-principle administrative approval, the first step in capital acquisition. It is not a contract or a purchase order.

Army items

The Army proposals include the anti-UAV electronic warfare system AKASH TARANG, MPATGM, MRSAM, V-SHORADS, an Active Protection System for tanks and jet-based kamikaze drones.

Navy items

The Navy proposals cover the Multi Influence Ground Mine, the Naval Shipborne Unmanned Aerial System and a Land Based Testing Facility for Electric Propulsion Systems.

Air Force item

The Air Force proposal is for a Fixed-Wing High Altitude Pseudo Satellite (FW-HAPS) for persistent surveillance, telecommunication and remote sensing.

DAC origin

The DAC was set up in 2001 after the Group of Ministers' review following the Kargil conflict.

Don’t confuse with AoN vs contract: AoN only allows the procurement process to begin. The contract is signed much later, after trials and negotiation, and is cleared by the competent financial authority.

Don’t confuse with MRSAM vs V-SHORADS: MRSAM gives medium-range air defence against stand-off aerial threats. V-SHORADS is a very short range system, a shorter-range layer of defence.

Defence: Prelims tests exercises (with whom), equipment (who makes it) and firsts.

UPSC’s own questions that come close to this issue, from our Prelims and Mains banks.

Technology

The project uses Japanese Shinkansen technology and operational practices.

Track system

J-Slab ballastless track is being introduced in India for the first time.

Opening plan

The first service is expected in August 2027, with the Surat to Vapi section opening first.

Don’t confuse with MAHSR vs Vande Bharat: MAHSR bullet trains have a design speed of up to 350 kmph. Vande Bharat trains have a design speed of 180 kmph.

Don’t confuse with Design speed vs operational speed: Design speed (350 kmph) is what the system is built for. Operational speed (320 kmph) is the speed at which trains will run in service.

UPSC’s own questions that come close to this issue, from our Prelims and Mains banks.

Drill

Pashujanya Yudh Abhyas is the third national-level mock drill under the National One Health Mission.

Place and dates

It was held at Khari village, Vidisha district, Madhya Pradesh, over five days from 29 June to 3 July 2026.

Scenario

The scenario was an Influenza A (H1N1) outbreak in animals with potential spillover to humans and wildlife.

Response team

Experts from animal health, human health and wildlife worked under the National Joint Outbreak Response Team (NJORT).

BSL-3 labs

Laboratories of the National BSL-3 Network took part, namely ICAR-NIHSAD, Bhopal and AIIMS Bhopal.

Don’t confuse with One Health approach vs National One Health Mission: One Health is the concept linking human, animal and environmental health. The Mission is the government programme that puts it into practice.

Board of Trade

It is the apex consultative platform of the Department of Commerce, chaired by the Commerce Minister. Members include States, Export Promotion Councils, industry chambers and non-official members.

BHAVYA scheme

The scheme has an outlay of ₹33,660 crore to develop 100 industrial parks. Its first round is currently open to States.

USD 1 trillion target

DGTR

The Directorate General of Trade Remedies can recommend anti-dumping and safeguard measures for industries hurt by dumping or predatory pricing. It runs outreach such as Jan Sunwai.

Aim and outlay

Cabinet approved the scheme with an outlay of ₹33,660 crore to build 100 industrial parks over six years.

Implementing agency

NICDC is the Project Management Agency, responsible for implementation and monitoring, and built the BHAVYA Portal.

Centre-State model

States provide the land. The Centre supports infrastructure through NICDC, which partners with States under a 51:49 model.

Park sizes

Parks start at 25 acres in hilly areas, smaller UTs and the Northeast, run to 100-500 acres in mid-sized States, and reach up to 1,000 acres near cities.

The portal handles DPR submission, appraisal and real-time monitoring, and supports the challenge-based selection.

Scale and period

100 industrial parks over six years, 2026-27 to 2031-32, with an outlay of about ₹33,660 crore.

First phase

Up to 50 parks will be taken up through a challenge-based competitive selection.

Implementation vehicle

Projects are executed by SPVs incorporated under the Companies Act, 2013.

Funding form and agency

Assistance is equity contribution linked to the value of land transferred to the SPV and to milestones. NICDC is the Project Management Agency.

Oversight

The National Level Steering Committee is chaired by the Secretary, DPIIT; GIS-based monitoring is used.

Design principles

Parks follow PM GatiShakti principles and use underground utility corridors (no-dig environment).

NICDC

NICDC under DPIIT is implementing 20 projects across 13 states.

Don’t confuse with Export Promotion Mission vs Districts as Export Hubs: The Mission is a ₹25,000 crore financial support scheme for exporters. Districts as Export Hubs is an initiative to build export capacity at district level, now with a 90-day drive in 120 districts.

Don’t confuse with Anti-dumping duty vs safeguard duty: Anti-dumping duty counters unfairly priced imports from specific countries. Safeguard duty counters a sudden import surge, whatever the source, and needs no unfair practice.

Don’t confuse with BHAVYA vs Board of Trade: BHAVYA is an industrial parks scheme. The Board of Trade is a consultative body on trade policy under the Department of Commerce.

Don’t confuse with DPIIT vs NICDC: DPIIT issued the operational guidelines. NICDC is the Project Management Agency that implements and monitors the scheme.

Don’t confuse with NICDC vs DPIIT: DPIIT is the ministry department that frames the scheme; NICDC is the agency that manages and monitors it.

Don’t confuse with BHAVYA vs PM MITRA: BHAVYA covers 100 general industrial parks via NICDC; PM MITRA parks are textile-specific under the Ministry of Textiles, with NICDC as project management agency.

Don’t confuse with NICDC vs NICDP: NICDC is the company implementing; NICDP is the programme for industrial corridors.

Don’t confuse with BHAVYA vs NICDP: NICDP builds greenfield Industrial Smart Cities along corridors through NICDC; BHAVYA funds plug-and-play parks in all States through challenge mode.
