NITI Aayog released a strategy document for internationalising India's higher education, targeting 8 lakh inbound international students by 2047.

• Current inbound students: approximately 50,000 international students are enrolled in Indian universities, a fraction of the capacity.
• Outbound students: 13 lakh Indian students study abroad, creating a net education deficit both financially and in human capital terms.
• Education remittances outflow: approximately $3.4 billion in FY 2023-24 spent by Indian students at foreign institutions.
• Target: 8 lakh international students in India by 2047 (India at 100), requiring a 16-fold increase.
• India's competitive advantage: higher education is 30-40% cheaper in India than in Western destinations.
• Size of the sector: India has over 1,200 universities and 40 million students enrolled, the world's largest higher education system by enrolment.
• Proposed instruments:
  • Vishwa Bandhu Fellowship: merit-cum-means scholarships for international students to study at Indian institutions.
  • Tagore Academic Mobility Framework: structured exchange agreements between Indian and foreign universities modelled on the EU's Erasmus programme.

India and New Zealand concluded FTA negotiations in December 2025, nine months after the talks were launched in March 2025. It is the fastest FTA India has ever concluded.

• Negotiation duration: nine months from launch (March 2025) to conclusion (December 2025). This is a record speed for India's FTA process.
• Trade target: the two countries aim to double bilateral trade to $5 billion within five years of the agreement's entry into force.
• Current trade: $1.3 billion in FY 2024-25, a 49% year-on-year growth.
• New Zealand investment: New Zealand committed to $20 billion in investment in India over 15 years.
• India's tariff offer: India offers duty concessions on 95% of tariff lines.
• New Zealand's offer: 100% duty-free access to the New Zealand market for Indian goods.
• Labour mobility: 5,000 temporary employment visas per year for Indian workers in New Zealand, for stays of up to three years.
• Context: India's earlier FTAs with West Asian countries (UAE 2022, Oman 2025) and with Australia (2022) reflect a shift toward faster, bilateral-first trade architecture outside the WTO's stalled multilateral track.

The Ministry of Electronics and Information Technology issued an alert about a WhatsApp cyberattack technique called "Ghost Pairing" that allows an attacker to link a victim's WhatsApp account to a separate device.

• Attack name: Ghost Pairing.
• Issuing agency: Ministry of Electronics and Information Technology (MeitY).
• Mechanism: the attacker uses social engineering to trick the victim into sharing a WhatsApp verification code. Using this code and a malicious link, the attacker links the victim's WhatsApp account to a device the attacker controls via WhatsApp's "Linked Devices" feature.
• No SIM swap needed: unlike traditional account takeover methods, Ghost Pairing does not require the attacker to port or clone the victim's SIM card.
• Access gained: once linked, the attacker receives all incoming messages, media files and contacts in real time on their device.
• Detection method: check WhatsApp settings under "Linked Devices". Any unrecognised device listed should be removed immediately.
• Legal provision: unauthorised access to computer resources and communication devices falls under Sections 43 and 66 of the Information Technology Act 2000.

NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, launched in November 2013, lost contact with ground controllers in December 2025.

• Full name: Mars Atmosphere and Volatile EvolutioN.
• Launch date: 18 November 2013.
• Arrival at Mars: September 2014.
• Mission type: Mars orbiter studying the upper atmosphere and ionosphere.
• Scientific payload: eight instruments measuring solar wind, ionosphere, plasma, ultraviolet radiation and magnetic fields.
• Key finding: solar wind has stripped away much of Mars' early atmosphere over billions of years, explaining why Mars lost its liquid surface water. This was confirmed definitively by MAVEN data.
• Secondary role: MAVEN served as a data relay satellite for the Curiosity and Perseverance surface rovers, passing their science data back to Earth when line-of-sight geometry made direct contact difficult.
• Duration: approximately 12 years of operational service before loss of contact.

The Pa Pa Pagli project in Dahod district, Gujarat deploys a play-based early childhood education methodology in tribal Anganwadi centres, supported by UNICEF India.

• Location: Dahod district, Gujarat. Dahod is one of India's most heavily tribal districts.
• Supporting agency: UNICEF India.
• Target group: children aged 3 to 6 years enrolled in Anganwadi centres under the Integrated Child Development Services (ICDS) scheme.
• Methodology: play-based learning using structured activities, songs and group games rather than formal instruction. The approach is designed to be low-cost and replicable.
• Scientific basis: approximately 85% of human brain development occurs before age six. Quality early childhood stimulation permanently shapes cognitive architecture, language acquisition and social skills.
• Problem addressed: tribal and rural children in Dahod historically arrived at Class 1 without foundational literacy or numeracy readiness, compounding learning deficits that persist through schooling.
• Linkage to national policy: NEP 2020 mandates universal access to quality early childhood care and education. ICDS is the main vehicle at the community level.

Baylisascaris procyonis, a nematode parasite found in raccoons, has been detected in nine European countries, raising concerns about its spread as an invasive zoonotic disease.

• Scientific name: Baylisascaris procyonis.
• Common name: Raccoon Roundworm.
• Natural host: raccoons (Procyon lotor), native to North America.
• Geographic spread: now reported in nine European countries following the spread of raccoon populations there.
• Transmission: humans and other animals are infected by accidental ingestion of eggs from contaminated soil or water. Eggs become infectious 2-4 weeks after being shed in raccoon faeces.
• Environmental persistence: eggs can survive in soil for years, making decontamination difficult.
• Human pathology: larvae migrate to organs including the liver (causing enlargement), the central nervous system (causing permanent neurological damage) and the eyes (causing blindness). Severe cases are often fatal or leave permanent disability.
• Prevention: no commercial human vaccine exists. Prevention relies on avoiding contact with raccoon faeces and thorough handwashing.
• Zoonosis definition: a disease naturally transmissible from vertebrate animals to humans.

The growing number of micrometeoroids and orbital debris (MMOD) in Low Earth Orbit is raising the risk of a cascade failure known as Kessler Syndrome.

• MMOD: Micrometeoroids and Orbital Debris. Micrometeoroids are natural particles from space; orbital debris is man-made.
• Tracked objects: approximately 34,000 pieces of debris larger than 10 cm are tracked by space surveillance networks as of 2025.
• Orbital regime: most concentrated in Low Earth Orbit (LEO), between 200 and 2,000 km altitude.
• Collision velocity: debris travels at 10-72 km/s. At these speeds a 1-cm fragment carries the kinetic energy of a hand grenade.
• Kessler Syndrome: a theoretical cascade where one collision generates debris that causes further collisions, in a self-sustaining chain that eventually makes certain orbital bands unusable. Named after NASA scientist Donald Kessler.
• ASAT test contribution: anti-satellite missile tests create large debris clouds that persist for years. India's 2019 Mission Shakti test, Russia's 2021 ASAT test and China's 2007 ASAT test are the three largest debris-generating events in history.
• Mitigation: international guidelines recommend deorbiting LEO satellites within five years of end of life. Active debris removal is still experimental.
