Recently, a deadly accident occurred at the pharma unit of Sigachi Industries in Hyderabad, raising the death toll to 36. The unit manufactures Microcrystalline Cellulose (MCC). Microcrystalline Cellulose (MCC) is a free-flowing powder extracted from refined wood pulp. It is inert, nontoxic, fiber-rich, chewable, and not absorbed during digestion. Wood is the main source of pharmaceutical MCC, with cellulose chains bound by polymers and hydrogen bonds.
42. Which organization has launched the “3 by 35” Initiative to tackle non-communicable diseases (NCDs)?
[A] United Nations Development Programme (UNDP)
[B] Food and Agriculture Organization (FAO)
[C] World Health Organization (WHO)
[D] None of the Above
Show Answer
Correct Answer: C [World Health Organization (WHO)]
Notes:
Recently, the World Health Organization (WHO) launched the “3 by 35” Initiative to tackle non-communicable diseases (NCDs). It urges countries to raise taxes on tobacco, alcohol, and sugary drinks to achieve at least a 50% real price increase by 2035. NCDs like heart disease, cancer, and diabetes cause over 75% of global deaths. Higher taxes could prevent 50 million premature deaths over 50 years and generate USD 1 trillion in public revenue in the next decade. Between 2012 and 2022, around 140 countries already raised tobacco taxes, showing large-scale change is achievable.

It weighs 4.5 tonnes, spans 17.8 metres, and will serve Israel’s communication needs for the next 15 years. The satellite orbits 36,000 km above Earth, maintaining constant coverage over Israel and nearby regions.
45. Which institute has developed a bamboo-polymer composite as an eco-friendly alternative to plastic in vehicle interiors?
[A] IIT Guwahati
[B] IIT Delhi
[C] IIT Ahmedabad
[D] IIT Bombay
Show Answer
Correct Answer: A [IIT Guwahati]
Notes:
Recently, IIT Guwahati researchers developed a bamboo-polymer composite as an eco-friendly alternative to plastic in vehicle interiors. The composite uses Bambusa tulda, a fast-growing bamboo species from Northeast India. It is fused with biodegradable polymers to create a cost-effective and sustainable material. The research was published in the journal Environment, Development and Sustainability. It shows high strength, thermal stability, and low moisture absorption, making it suitable for real-world use.
46. Which space organization has launched a twin satellite mission called “TRACERS” to study Earth’s magnetic shield?
[A] European Space Agency (ESA)
[B] National Aeronautics and Space Administration (NASA)
[C] Japan Aerospace Exploration Agency (JAXA)
[D] Indian Space Research Organisation (ISRO)
Show Answer
Correct Answer: B [National Aeronautics and Space Administration (NASA)]
Notes:
Recently, NASA launched a twin satellite mission called TRACERS, which stands for Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites. The satellites were launched from Vandenberg Space Force Base, California, aboard a SpaceX Falcon 9 rocket. The mission aims to study magnetic reconnection, a powerful process where magnetic field lines snap and release energy. This process happens when solar wind, a stream of charged particles from the Sun, interacts with Earth’s magnetosphere (magnetic shield).
47. Which organisation launched the Cancer AI & Technology Challenge (CATCH) Grant Program along with the National Cancer Grid (NCG)?
[A] Indian Council of Medical Research (ICMR
