How US Fed Rate Cut Could Impact the Indian Market?
Syllabus: GS3/ Economy
Context
- The United States Federal Reserve announced that it will cut the benchmark interest rate, the Federal Funds Rate, by 50 basis points, or half a percentage point.
About
- A cut in interest rate typically incentivises economic activity, promotes growth, and increases job creation by making it cheaper for people to borrow money.
- Conversely, a hike in interest rates or persistently high interest rates tend to drag down economic growth and employment generation.
Impact on Indian economy
- India is a capital-scarce economy, and lower interest rates in the US will likely incentivise global investors to borrow in the US and invest in India, in stocks, debt, or in the form of foreign direct investment (FDI).
- Repeated lowering of interest rates in the US will also lead to some weakening in the US dollar’s exchange rate with other currencies such as the Indian rupee.
- This, in turn, will impact India’s exporters (adversely) and importers (positively).

Union Cabinet Approved Bharatiya Antariksh Station (BAS)
Syllabus :GS 3/Space
Context
- The union cabinet chaired by Prime Minister Narendra Modi has approved the building of the first unit of the Bharatiya Antariksh Station (BAS) by extending the scope of Gaganyaan program.
About
- The first module of BAS will be launched in 2028 and by 2035 the fully operational indigenous space station will be created.
- The BAS will be placed in low earth orbit, at 400 km above the earth’s surface.
- The revised Gaganyaan Programme to include the scope of development and precursor missions for BAS, and factoring one additional uncrewed mission and additional hardware requirement for the developments of ongoing Gaganyaan Programme. Now the human spaceflight program of technology development and demonstration is through eight missions to be completed by December 2028 by launching the first unit of BAS-1.
- The 52-tonne space station will serve as a research platform for Indian astronauts and scientists to conduct experiments in microgravity, astronomy and Earth observation, and will allow astronauts to stay in orbit for 15-20 days.
Do you know?
- Currently, there are only two operational space stations – the International Space Station (ISS), developed in cooperation by the United States, Russia, Japan, Europe and Canada; and China’s Tiangong Space Station (TSS).

Circumnutations
Syllabus: GS3/ S&T
In News
- The study reveals the role circumnutations could play in plant growth patterns.
- In this study, researchers found that sunflowers grown in a dense row naturally formed a near-perfect zigzag pattern, with each plant leaning away from the row in alternating directions.
About Circumnutation
- It refers to the slow, repetitive, and often spiral movement observed in the growing tips of plants, such as shoots, tendrils, and roots.
- This movement is caused by differential growth rates in different parts of the plant, particularly in the apical meristem, leading to a helical or circular motion.
- Examples:
- Tendrils of climbing plants exhibit circumnutation to locate and coil around supports.
- Roots may use circumnutation to navigate through soil, finding the best path for growth.

Amoebic Meningoencephalitis
Syllabus: GS 3/ Science and technology
In News
- Kerala has initiated research on amoebic meningoencephalitis through a One Health platform to study environmental factors and improve diagnostic methods.
About Amoebic Meningoencephalitis
- It is a rare but lethal central nervous system infection caused by free-living amoebae (FLA) found in freshwater, lakes, and rivers.
- Types of Amoebic Encephalitis:
- There are two types—Primary Amoebic Meningoencephalitis (PAM) caused by Naegleria fowleri, and Granulomatous Amoebic Encephalitis (GAE).
- Both have high fatality rates, with PAM primarily affecting children and young adults.
- PAM often occurs in warm climates and during the summer months. Swimming in warm, stagnant freshwater, or using unsterilized water for nasal irrigation, are major risk factors.
- Amoeba Growth and Climate Change: Rising water temperatures due to climate change are expected to increase encounters with N. fowleri, which thrives in warm, stagnant water bodies.
- Symptoms and Diagnosis Challenges: PAM presents with symptoms similar to bacterial meningitis, making early diagnosis difficult. Delays in diagnosis often lead to rapid brain damage and death.
- Introduction of Miltefosine: Miltefosine, an anti-parasitic drug, was a key addition to the treatment protocol, alongside Amphotericin B, contributing to better outcomes in patients
