Science and Technology News

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Science and Technology News in LAT Current Affairs covers developments from the last ~12 months across space missions, AI, biotechnology, defence technology, and Pakistan’s indigenous scientific milestones. LAT typically asks 1–3 MCQs here, worth roughly 3% of the paper, so it is a high-return topic for minimal time investment.

You must remember three agency attributions clearly: SUPARCO handles satellites and space research; PAEC (Pakistan Atomic Energy Commission) handles nuclear energy and isotopes; PNRA is the regulator, while NESCOM builds missiles. Confusing these is the single most common trap.

Know one flagship mission per major power: India’s Chandrayaan-3 (lunar south pole, 2023), NASA’s Artemis II (crewed lunar flyby), China’s Tiangong space station, and Pakistan’s PakSat MM1 communications satellite launched in 2024. For AI, recognise generative AI (ChatGPT, Gemini) as the dominant sub-topic examiners test. For biotech, know the term CRISPR-Cas9 gene editing.

🟡 Standard — Regular Study (2d–2mo)

Standard content for students with a few days to months.

Scope of the Topic

LAT defines this section as recent developments only — roughly the preceding 12 months. Static textbook science (Newton’s laws, photosynthesis) does not belong here. The examiner tests whether the candidate reads newspapers such as Dawn, The News, and the Express Tribune science desk.

Pakistan-Specific Developments (highest weightage)

Pakistani scientific news is consistently over-represented relative to its global footprint because LAT is a Pakistan-administered test.

• PakSat MM1: Pakistan’s geostationary communications satellite launched by SUPARCO in May 2024 from China’s Xichang Satellite Launch Centre, intended to improve broadband and TV broadcasting.
• PRSS-1 and PakTES-1A: Earlier optical Earth-observation satellites co-developed with China.
• PAEC milestones: Operation of Karachi Nuclear Power Plant (KANUPP) units K-2 and K-3, both Hualong One reactors developed with China, contributing roughly 2,200 MW to the national grid.
• Agricultural biotech: Pakistan’s cotton genome sequencing and development of Bt cotton varieties at NIBGE.
• Anti-polio and COVID campaigns: NCOC-coordinated vaccination drives using locally filled syringes.

Global Space and AI Track

• Chandrayaan-3 (India, August 2023) made India the first country to soft-land near the lunar south pole.
• Artemis II (NASA, scheduled 2025) is the first crewed lunar flyby since Apollo 17 (1972).
• Generative AI: ChatGPT (OpenAI, launched November 2022), Google Gemini, and Anthropic Claude are repeatedly tested for authorship or capability questions.
• CRISPR-Cas9: The first FDA-approved CRISPR therapy, Casgevy, was approved in December 2023 for sickle cell disease.

Common Question Patterns

Question Type	Example
Agency attribution	”PakSat MM1 was launched by which organisation?”
Mission identification	”Which lunar mission landed near the south pole in 2023?”
Country–achievement pairing	”Which country approved Casgevy in 2023?”
Acronym disambiguation	”PAEC vs PNRA — which is regulatory?”

🔴 Extended — Deep Study (3mo+)

Comprehensive coverage for students on a longer study timeline.

Edge Cases and Acronym Disambiguation

The acronyms form a matrix that examiners exploit heavily. Memorise the four-way split:

Acronym	Full Form	Function
SUPARCO	Space and Upper Atmosphere Research Commission	Satellites, space science
PAEC	Pakistan Atomic Energy Commission	Nuclear power plants, isotopes, medicine
PNRA	Pakistan Nuclear Regulatory Authority	Safety regulation of nuclear facilities
NESCOM	National Engineering and Scientific Commission	Strategic missiles (e.g., Babur, Ghaznavi)

Candidates frequently credit SUPARCO with nuclear weapons or PAEC with satellite launches — both wrong.

Defence and Strategic Technology

LAT occasionally frames S&T through the South Asian strategic lens. Pakistan’s Shaheen-III ballistic missile has a reported range of 2,750 km; India’s Agni-V ICBM class missiles and BrahMos cruise missile (jointly with Russia) are common distractors. In avionics, the JF-17 Thunder Block-III indigenously co-produced with China carries beyond-visual-range PL-15 missiles. The Akash and S-400 systems (Russian, operated by India) appear as comparison points.

Climate, Energy, and Semiconductors

IPCC’s AR6 Synthesis Report (2023) and the outcomes of COP28 (Dubai, 2023) — notably the first call to “transition away from fossil fuels” — are examinable. EV policy: Pakistan’s 2024 Electric Vehicle Policy targets 30% of two- and three-wheeler sales to be electric by 2030. On semiconductors, the US CHIPS and Science Act (2022) and India’s Semicon India programme ($10 billion incentive) shifted global manufacturing geography.

Common Mistakes

• Treating viral social media posts as peer-reviewed breakthroughs — LAT expects verifiable, source-attributed news.
• Confusing launch date with landing date for lunar missions.
• Citing ChatGPT as a “search engine” — it is a large language model.
• Assuming all Pakistani satellites are built entirely domestically; most involve Chinese launch services or payload collaboration.

Practice Prompts

1. PakSat MM1 was launched in 2024. Identify the launching agency, launch site, and primary function. (Answer: SUPARCO, Xichang Satellite Launch Centre China, geostationary communications for broadband and broadcast.)
2. Match the following to the correct Pakistani body: nuclear safety regulation / satellite launch / Babur missile development. (Answer: PNRA / SUPARCO / NESCOM.)
