A group of students was provided a first-hand experience of the Zero Shadow Day (ZSD) phenomenon at an event organized by the Pondicherry Science Forum (PSF).
What is Zero Shadow Day?
- Zero Shadow Day occurs twice every year in locations between the Tropics of Cancer and Capricorn, where the Sun is positioned directly overhead at noon.
- The shadow typically appears elongated on the ground while being observed under normal circumstances.
- However, when the shadow perfectly aligns under the object, during a short period of time, it remains absent on the ground.
- This happens when the sun reaches the zenith, its highest point of revolution.
- The dates of the occurrence may vary depending on the specific location and its latitude.
Why does Zero Shadow Day occur?
- Zero Shadow Day is caused due to Earth's axial tilt of approximately 23.5 degrees and its orbit around the Sun.
- The Sun is never overhead causing it to maintain a slightly lower altitude either north or south.
- The tilting position is also responsible for different seasons on Earth.
- As the Earth orbits the sun, the angle at which the sun's rays hit the Earth's surface changes, causing shadows to be cast in different directions.
- In regions falling between the Tropic of Cancer (about 23.5 degrees north of the equator) and the Tropic of Capricorn (about 23.5 degrees south of the equator), there are instances when the Sun is exactly overhead.
- Since the sun's rays come down almost vertically, there is no or little shadow on vertical objects.

Each organ transplant case will receive a distinctive National Organ and Tissue Transplant Organisation (NOTTO) ID assigned to both the donor and the recipient.
Highlights of the News:
- The Union Health Ministry has mandated the cessation of commercial organ transactions, particularly those involving foreign nationals, and emphasized the need for stringent oversight by local authorities.
- For deceased donor transplants, a NOTTO-ID is required for organ allocation, while in living donor transplants, the ID must be generated within 48 hours post-surgery through the NOTTO website by the hospital.
What is the National Organ and Tissue Transplant Organization (NOTTO)?
- NOTTO is a national organization established under the Directorate General of Health Services, Ministry of Health and Family Welfare, Government of India.
It serves as the central coordinating hub for:
- Organ and tissue procurement and distribution.
- Maintaining a registry of organ and tissue donation and transplantation activities across the country.
NOTTO comprises two divisions:
- National Human Organ and Tissue Removal and Storage Network:
- Acts as the primary center for nationwide coordination of organ and tissue procurement, distribution, and registry.
- Established in accordance with the Transplantation of Human Organs (Amendment) Act 2011.
- National Biomaterial Centre (National Tissue Bank):
- This center focuses on filling the gap between demand and supply while ensuring quality assurance in tissue availability.
- The Transplantation of Human Organs (Amendment) Act 2011 has expanded NOTTO's scope to include tissue donation and registration of tissue banks.
Activities performed by NOTTO include:
-
- Coordinating tissue procurement and distribution
- Donor tissue screening
- Tissue removal and storage
- Tissue preservation
- Laboratory screening of tissues
- Tissue tracking
- Sterilization
- Record maintenance
- Data protection and confidentiality
- Quality management in tissues
- Patient information on tissues
- Developing guidelines, protocols, and standard operating procedures
- Training and assistance in registering other tissue banks

The International Monetary Fund (IMF) released the latest global financial stability.
About Global Financial Stability Report (GFSR):
- The Global Financial Stability Report (GFSR) is a semiannual report by the International Monetary Fund (IMF).
- It is released twice per year, in April and October.
- The GFSR provides an assessment of the global financial system and markets and addresses emerging market financing in a global context.
- It focuses on current market conditions, highlighting systemic issues that could pose a risk to financial stability and sustained market access by emerging market borrowers.
Key Points from the Report:
- The report highlights significant risks facing the global financial system, including persistent high inflation, increased lending in unregulated credit markets, and a rise in cyber-attacks targeting financial institutions.
- It underscores geopolitical tensions, such as conflicts in West Asia and Ukraine, as potential factors disrupting aggregate supply and driving up prices, possibly constraining central banks from lowering interest rates.
- India emerged as the second-largest recipient of foreign capital in 2023, following the United States, though this trend could shift rapidly if Western central banks signal prolonged high-interest rates.
- Of concern is the expansion of the unregulated private credit market, where non-bank financial institutions extend credit to corporate borrowers, posing potential threats to the broader financial system.
- Many borrowers in this market lack financial stability, with numerous entities unable to cover interest costs with current earnings, highlighting underlying risks.

- He recruited Denis Hayes, a young activist, to manage the campus teach-ins and to scale the idea of environment conservation to a broader public.
- They choose April 22, a weekday between Spring Break and Final Exams, to increase student participation.
- Its immediate success was evident with a massive turnout of 20 million people across the US.
- By 1990, Earth Day became a global event transcending national borders.
Earth Day Significance:
