Fighting Dengue with Wolbachia Google''s parent company Alphabet has proposed releasing 32 million Wolbachia-infected male mosquitoes in parts of Florida and California to reduce disease transmission by sterilizing wild Culex mosquitoes (West Nile virus). » Only male mosquitoes are released because males do not bite humans. Wolbachia » Wolbachia is a naturally occurring bacterium found in many insect species. » It also does not naturally occur in Aedes aegypti mosquitoes, the main carriers of dengue, Zika, chikungunya, and yellow fever. Working of Wolbachia » Virus Blocking: Wolbachia prevents viruses such as dengue, Zika, and chikungunya from multiplying inside mosquitoes, reducing disease transmission. » Population Suppression: Non-viable eggs are produced when Wolbachia-infected males mate with uninfected females, lowering mosquito populations. |

(as announced in Union Budget FY2026-27) o Earlier, only NRIs/OCIs were allowed to invest in PIS. » Individual investment limit for a PROI in a company doubled from 5% to 10% (aggregate Limit raised to 24%). Tax Exemption for Foreign Portfolio Investments (FPIs) Investing in G-Secs » Income Tax on Interest and Capital Gain Tax waived on FPIs and investments by Bank for International Settlements in G-Secs. » Reforms in FPI Investment in Government Securities (G-Secs) » Fully Accessible Route (FAR): expanded to include 15-, 30-, and 40-year tenor G-secs and Sovereign Green Bonds. o FAR allows non-residents to invest in "specified securities" without any quantitative restrictions » Removed three restrictions under General Route, viz. short-term investment limit, concentration limit and the security-wise limit. Key Terms » FPI: Involves investors holding financial assets, such as stocks and bonds in another country. It does not provide direct ownership of company’s assets and is relatively liquid, depending on volatility. o Investment by a single FPI (or investor group) in any Indian company must not exceed 10% of total paid-up equity capital. » G-Sec: It is a tradeable instrument issued by Central or State Governments. It acknowledges the government’s debt obligation. |

JPN Bird Sanctuary Becomes India’s 100th Ramsar Site Jai Prakash Narain Bird Sanctuary (Surha Tal) » It is a natural, perennial oxbow lake (U-shaped waterbody formed when a wide meander from a river is cut off). » Location: Ballia district, Uttar Pradesh » Origin: Consolidated in 1991 from the land areas of 45 villages as Surha Tal. Renamed in 2002 to honour activist and political leader, Jai Prakash Narayan. » Area: ~3432 hectares which expands to ~25,000 hectares during monsoons. » Significance: o Rich avifaunal biodiversity: Vital wintering ground for migratory birds traveling along the Central Asian Flyway. Ø Notable fish include the vulnerable Wallago attu and Bagarius bagarius. Ø The abundance of fish attracts the vulnerable fishing cat (Prionailurus viverrinus). o Major source of irrigation and groundwater recharge. o Historical, cultural, and religious value. Ramsar Convention » It is the intergovernmental treaty that provides the framework for the conservation and wise use of wetlands and their resources. » It was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975. o India ratified the Convention in 1982. » Three Pillars o Conservation of wetlands of international importance. o Wise use of all wetlands. o International cooperation on shared wetlands and migratory species. » Criteria: A wetland must meet at least one of nine criteria established by the Convention. |

Kodaikanal Observatory Sheds Light on Sun’s Rhythm It uncovered how supergranulations respond to solar cycles, aiding cycle prediction. » Supergranulations are giant convection cells (or patterns) that form a vast network structure on the surface of the Sun. Solar Cycle » The solar cycle is a periodic rhythm of magnetic activity that Sun undergoes every ~11 years. o Mechanism: The Sun is composed of electrically charged gas (plasma) that generates a massive magnetic field. o Every 11 years, this field undergoes a flip (north-south poles switch) » This periodic cycle undergoes distinct phases: o Solar Minimum: Cycle begins at solar minimum (low activity and few sunspots) Ø Sunspots: Dark, cooler regions on the Sun caused by strong magnetic activity. Ø Despite being cooler, more sunspots correlate with the Sun emitting more total energy. o Solar Maximum: As activity builds toward solar maximum, Sun becomes "stormy," featuring the highest number of sunspots and frequent eruptions. » Impact on Space Weather: During the more active phases, the Sun also experiences an increase in giant eruptions, such as solar flares and coronal mass ejections (CMEs). o Solar Flares: Sudden bursts of X-rays and radiation (travelling at speed of light) caused by release of magnetic energy in sunspot regions. o CMEs: Massive bubbles of plasma and magnetic fields flung into space o Impact: They can disrupt power grids, navigation systems, radio communications, and satellite operations, affect astronauts, induce geomagnetic storms affecting magnetic fields and events like Auroras etc. Kodaikanal Solar Observatory » Established in 1899 and subsumed then Madras Observatory. » Aim: to obtain data on how Sun heats up Earth’s atmosphere and to understand monsoon patterns. » Location: under Indian Institute of Astrophysics and is located in Palani range (Tamil Nadu) o Chosen for its proximity to equator and its dust-free high-altitude location. |
