INTERNATIONAL UPDATES:

 

1. Brigitte Bardot, French Cinema Icon, Dies at 91: Legendary French actress and singer “Brigitte Bardot”, a defining cultural figure of the 1950s and 1960s, has died at the age of 91. Her death was announced by the Brigitte Bardot Foundation, which did not disclose details regarding the time or place of her passing. The foundation described her as a world-renowned artist who gave up fame to devote her life to animal welfare. Born in Paris in 1934, Bardot rose to international fame with the 1956 film “And God Created Woman”, directed by “Roger Vadim”, her first husband. The film transformed her into a global sex symbol and redefined post-war femininity in cinema. She went on to star in major French films such as “The Truth”, “Very Private Affair”, and “Jean-Luc Godard”’s “Contempt”, cementing her place in film history.

 

2. Jayshree Ullal Tops Hurun India Rich List 2025: Indian-origin technology leader “Jayshree Ullal” has emerged as the richest Indian-origin professional manager in the world after securing the top position on the Hurun India Rich List 2025. Her rise reflects the growing global influence of Indian-origin executives in shaping the technology sector. According to the Hurun report, Ullal’s net worth is estimated at ₹50,170 crore, placing her ahead of several high-profile global technology leaders. The ranking positions her above peers such as “Satya Nadella” and “Sundar Pichai”, highlighting a shift in how professional managers with equity stakes are represented on global rich lists. Ullal has served as President and CEO of “Arista Networks” since 2008. Under her leadership, the company has grown into a major player in cloud networking, providing high-performance solutions for hyperscale data centres, cloud service providers and large enterprises. In 2024, Arista reported revenues of about $7 billion, marking nearly 20 per cent year-on-year growth.

 

3. Why Israel’s Recognition of Somaliland Has Triggered Global Backlash: Israel’s decision to formally recognise Somaliland as an independent state has sent shockwaves across Africa and the Middle East, triggering swift diplomatic condemnation and raising fears of renewed instability in the already fragile Horn of Africa. While the move may appear symbolic, its geopolitical consequences are anything but — touching questions of sovereignty, regional rivalries, and the future of international norms around secession. Somaliland is a self-declared republic located in northwestern Somalia, with its capital in Hargeisa. It broke away from Somalia in 1991 after the collapse of the Siad Barre regime and a brutal civil war. Since then, it has functioned with its own government, currency, security forces and electoral processes.

Yet, no country had formally recognised Somaliland as a sovereign state until now. The international community has largely upheld Somalia’s territorial integrity, fearing that recognition of breakaway regions could encourage fragmentation across Africa, where colonial-era borders remain deeply sensitive.Mogadishu has consistently rejected Somaliland’s claim to independence, but lacks the political cohesion and military capacity to reintegrate the region by force.

 

4. Europe’s Russian Assets Dilemma: Why the EU Blinked — and What It Means for the Ukraine War: Last week’s European Union summit in Brussels marked a turning point in Europe’s handling of the Ukraine war. Instead of seizing Russia’s frozen sovereign assets — estimated at around €210 billion — the EU chose a far more cautious path: raising a €90-billion Eurobond to financially sustain Ukraine. The decision has exposed deep fractures within the bloc, sharpened anxieties about global finance, and underlined Europe’s growing fatigue with a war whose endgame remains elusive. At the heart of the summit’s drama was the question of Russia’s frozen wealth, much of it parked at Euroclear in Belgium. While the technical mechanisms for confiscation existed, the real barriers were political and legal.BelgiumItaly and Austria argued that outright seizure would violate international law and invite retaliation from Moscow — retaliation whose costs would fall unevenly on individual states. They insisted that any such move must involve collective burden-sharing. France’s last-minute shift in support of Italy effectively isolated Germany, which had been pushing hardest for a bolder approach.The outcome was a compromise that satisfied no one fully: Russian assets remain frozen indefinitely, but untouched.

 

OTHER UPDATES:

DEFENCE

 

1. China launches military encirclement drill near Taiwan: China has launched a large-scale military exercise encircling Taiwan, prompting the island to deploy its armed forces in response. The drill, announced on December 29, reflects heightened tensions across the Taiwan Strait and reinforces Beijing’s increasingly assertive posture toward the self-ruled island, which China claims as its own territory. China’s military said it had mobilised its army, navy, air force, and rocket units to conduct joint operations around Taiwan. The exercise, named “Just Mission 2025,” is being led by the Eastern Theatre Command and spans five maritime zones, including the Taiwan Strait and waters to the north, east, southeast, and southwest of the island. Beijing stated that the drills are intended to test combat readiness, improve joint operational capability, and issue a “serious warning” against any moves toward Taiwanese independence. Chinese authorities announced temporary sea and airspace restrictions in the designated exercise zones for a duration of 10 hours, beginning at 8:30 am local time. According to Shi Yi, spokesperson for the Eastern Theatre Command, the drills focus on sea-and-air combat readiness patrols, seizing comprehensive control, and simulating blockades of key ports and critical areas. Such scenarios closely align with potential contingency plans aimed at isolating Taiwan.

2. Iran launches three satellites with Russian Soyuz rockets: Iran has successfully placed three domestically developed satellites into low-Earth orbit using Russian Soyuz launch vehicles, further underscoring deepening strategic and technological cooperation between the two U.S.-sanctioned countries. The launch took place on December 28 and was confirmed by Iranian state media, marking another milestone in Tehran’s expanding space programme amid continued Western pressure over its nuclear activities. According to Iran’s official IRNA news agency, the satellites—Paya, Zafar-2, and a second unit of Kowsar—were carried aboard Russian Soyuz rockets. All three satellites are designed for low-Earth orbit operations. They are intended to support civilian applications such as monitoring agricultural productivity, managing natural resources, and assessing environmental conditions across Iran and neighbouring regions. Iran has increasingly depended on Russia to place satellites into orbit, particularly after facing restrictions on access to international launch services. The collaboration has expanded significantly since 2022, following Russia’s invasion of Ukraine. Western governments have accused Iran of supplying drones and missiles to Russia, allegations both countries have denied. Space cooperation has emerged as a visible and symbolic area of this growing partnership.

 

3. Poland Plans $2.2 Billion Anti-Drone Defence Shield: Poland has announced plans to construct a $2.2 billion multi-layered anti-drone defence system along its eastern border, citing rising security concerns linked to Russia’s military actions. The project reflects Warsaw’s growing focus on countering aerial threats and strengthening airspace security amid the prolonged Russia–Ukraine conflict. The decision follows several incidents involving suspected Russian drones entering Polish airspace. In one case earlier this year, multiple drones were detected crossing into Poland, prompting NATO fighter jets to scramble and causing debris damage on the ground. Polish authorities view these incidents as part of broader hybrid tactics aimed at testing regional defences rather than conventional military escalation. Deputy defence minister “Cezary Tomczyk” said the fortification will not resemble a single physical barrier. Instead, it will combine modern electronic warfare tools and conventional weapons. The system will include drone-jamming technologies, alongside machine guns, cannons and missile units. Initial operational capabilities are expected within six months, while full deployment is targeted within 24 months.

SCIENCE AND TECHNOLOGY

 

1. JWST Reveals Hidden Chemistry Around Young Star T Chamaeleontis: Astronomers have uncovered a rare glimpse into the chemical evolution of a young, planet-forming star system after a dramatic structural change exposed previously hidden molecular signatures. Observations of the star “T Chamaeleontis”, located about 350 light-years from Earth, show that a partial collapse of its circumstellar disk’s inner wall briefly illuminated complex organic chemistry, offering new insights into how planetary systems evolve. T Chamaeleontis, often referred to as T Cha, is a young, Sun-like star surrounded by a circumstellar disk containing a wide gap, likely carved by a forming protoplanet. Normally, the dense inner regions of such disks block ultraviolet radiation from reaching the outer disk. In 2022, however, a sudden burst of accretion caused part of this inner wall to thin or collapse, allowing ultraviolet light to stream outward and alter the disk’s chemical visibility. This unexpected illumination revealed strong signatures of polycyclic aromatic hydrocarbons (PAHs), flat, carbon-rich molecules considered important precursors to complex organic chemistry. Detecting PAHs around low-mass, Sun-like stars has been difficult due to their relatively weak ultraviolet output. The event at T Cha temporarily removed this limitation, making the molecules glow brightly in the mid-infrared range.

 

2. Lantana Camara Invasion Threatens Global Ecosystems: A silent ecological invasion is unfolding across vast regions of the world, driven by “Lantana camara”, an aggressive invasive weed now entrenched across tropical, subtropical and warm temperate zones. Easily recognised by its brightly coloured, bouquet-like flowers and strong scent, the plant has spread across millions of hectares, posing serious threats to biodiversityagriculture and forest ecosystems. Lantana camara spreads rapidly due to a combination of biological advantages. It releases chemicals into the soil that suppress the growth of neighbouring plants, a process known as allelopathy. Its leaves, flowers and berries are toxic to livestock, yet attractive to birds, insects and monkeys that disperse its seeds over long distances. Deep, spreading roots extract scarce water and nutrients, while a resin-coated leaf surface reduces moisture loss, allowing the plant to thrive in drought-prone and degraded soils.
