CSIR-CCMB Study (2022-24): Bacteria in 4 Metro Sewage Show Similar AMR Genes, Proposes Wastewater Surveillance Protocol

Candida auris Shows 90% Azole Resistance; Study Reveals Gene Duplication & Eagle Effect Challenging Antifungals

Fungal infections are rising due to global warming, with Candida auris emerging as a multidrug-resistant threat (30-40% mortality). New research from JNCASB and collaborators reveals that C. auris uses gene duplication (Erg11) and mutations (Fks1) to resist antifungals, and also exhibits the 'Eagle effect' where high drug doses paradoxically trigger compensatory chitin production, making the pathogen survive. This signals the end of the chemical arms race approach and calls for combination therapies and revised susceptibility testing limits.

DAE Proposes Reducing Land Need for 220 MWe Nuclear Reactors to 90 Hectares

The Department of Atomic Energy informed Parliament that land requirement for 220 MWe small nuclear reactors could be reduced from 330 hectares to about 90 hectares, subject to radiological impact assessment. This is part of India's push for Small Modular Reactors (SMRs) and opening the nuclear sector to private participation, with exclusion zones also proposed to be relaxed. The move is critical for energy security and decarbonization of hard-to-abate industries.

ICMR Study: 61% Gram-Negative Infections Carbapenem-Resistant; Mortality 39-51%

A large ICMR study across 20 Indian hospitals (2022-2025) reveals that carbapenem-resistant Gram-negative infections cause significantly higher mortality (39-51% in bloodstream infections) and cost 1.1-2 times more to treat. The study stresses that antimicrobial resistance is a complex interplay of healthcare transmission, antibiotic pressure, and diagnostic gaps, not just antibiotic overuse.

NPCIL Commences Fuel Loading at RAPP-8: 4th Indigenous 700 MWe PHWR in Fleet Mode

NPCIL has started initial fuel loading (IFL) at Unit 8 of Rajasthan Atomic Power Project (RAPP-8), a 700 MWe indigenous pressurised heavy water reactor (PHWR). This marks a major step in India's fleet-mode nuclear expansion, with commercial operation expected in 2026-27. For exams: understand PHWR technology, AERB's role, and the commissioning sequence (IFL → FAC → power generation).

IN-SPACe Releases Planned Re-entry Guidelines: Safety Threshold 1 in 10,000, Mandates Third-Party Liability Insurance

IN-SPACe has released new guidelines for planned re-entry of space objects, establishing a safety threshold of 1 in 10,000 risk to humans and mandating third-party liability insurance for private operators. This is crucial for India's human spaceflight mission Gaganyaan and the growing private space sector.

MeitY Summons Meta Global Team Over Algorithmic Bias; Parliamentary Panel to Question

Government summons Meta's global team to clarify algorithmic bias and role in public order after MeitY rejects technical glitch explanation. Parliamentary panel will also question the company. This highlights growing regulatory scrutiny on social media algorithms and their societal impact.

India Gets First Disease-Modifying Alzheimer's Drug Leqembi After CDSCO Nod

Eisai's Leqembi (lecanemab), India's first disease-modifying therapy for early Alzheimer's, has been launched after CDSCO approval. This marks a shift from symptomatic to disease-modifying treatment, but challenges of early diagnosis, biomarker infrastructure, and affordability remain significant.
