India has been elected as Co-Chair of the Regional Committee of the United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP) for a three-year term till 2028.

About United Nations Global Geospatial Information Management for Asia and the Pacific

The UN-GGIM-AP is one of the five regional committees of the United Nations Committee of Experts on Global Geospatial Information Management.
It is the apex inter-governmental mechanism for making joint decisions and setting directions with regard to the production, availability and use of geospatial information within national, regional and global policy frameworks.
History of UN-GGIM-AP
- It was initially established in 1995 as the Permanent Committee on GIS Infrastructure for Asia and the Pacific (PCGIAP).
- It was rebranded as UN-GGIM-AP in 2012, subsequent to the establishment of UN-GGIM in 2011.
Aim: To address global challenges regarding the use of geospatial information.
Members: It is represented by the National Geospatial Information Agencies of 56 countries in Asia and the Pacific region,
Functions: It works to maximize the economic, social, and environmental benefits of geospatial information through cooperation, capacity development, and shared solutions.
Secretariat: United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) serves as secretariat since 2018.

Scheme for Innovation and Technology Association with Aadhaar

October 17, 2025

Scheme for Innovation and Technology Association with Aadhaar Latest News

Recently, the Unique Identification Authority of India (UIDAI) has launched the Scheme for Innovation and Technology Association with Aadhaar (SITAA).

About Scheme for Innovation and Technology Association with Aadhaar

It was launched to strengthen India’s digital identity ecosystem and combat emerging security threats such as deepfakes, spoofing, and presentation attacks.
It aims to bring together startups, academic institutions, and industry players to co-develop secure, scalable, and globally benchmarked solutions that enhance Aadhaar authentication.
The program will particularly focus on advanced biometric technologies, authentication frameworks, artificial intelligence, and data privacy.
The SITAA pilot phase will roll out three targeted challenges designed to address critical areas of Aadhaar authentication security:
- Face Liveness Detection: Startups are invited to develop software development kits (SDKs) for passive and active face liveness detection.
  - Solutions must prevent spoofing through photos, videos, masks, morphs, deepfakes, and adversarial inputs.
- Presentation Attack Detection (PAD): Academic and research institutions can submit proposals for advanced PAD solutions that leverage AI/ML to detect a wide range of attacks, including print, replay, masks, morphs, and deepfakes.
  - Solutions must be privacy-compliant, scalable, and capable of real-time or near-real-time detection.
- Contactless Fingerprint Authentication: It focuses on developing SDKs for fingerprint authentication using standard smartphone cameras or low-cost imaging devices.
  - The solutions must ensure high-quality image capture, spoof detection, and compatibility with Aadhaar’s authentication ecosystem.

Q2: What information does an Aadhaar contain?

Ans: Personal details, biometric data, and demographic information.

Celestial Body –Chiron

Celestial Body –Chiron Latest News

Recently, astronomers for the first time observed a ring system formation around icy celestial body Chiron.

About Celestial Body –Chiron

Chiron is part of a class of objects called centaurs (which populate the outer solar system between Jupiter and Neptune), displaying characteristics of both asteroids and comets.
It was discovered in 1977 by astronomer Charles Kowal.

Features of Celestial Body –Chiron

It has a diameter of about 200 kilometers (125 miles) and takes about 50 years to complete one orbit around the sun.
Ring system: Its observations clearly showed that it is surrounded by well-defined 4 rings. The three inner rings are embedded within dust swirling around in a disk-like shape.
These rings are likely composed mainly of water ice mixed with small amounts of rocky material, like those of Saturn.
Composition: It mainly consists of rock, water ice and complex organic compounds.
Chiron exhibits occasional comet-like activity – ejecting gas and dust into space.
A method called stellar occultation was used by a team including Brazilian, French and Spanish researchers to observe the rings.

Celestial Body –Chiron FAQs

Q1: What is Chiron?

Q2: Why is Chiron considered significant?

Ans: It's a potential source of water and organic materials.

Chikungunya

October 17, 2025

Chikungunya Latest News

The New York State Department of Health recently confirmed the first locally acquired case of chikungunya in the United States in over six years.

About Chikungunya

It is a mosquito-borne viral disease caused by the chikungunya virus (CHIKV).
It causes fever and severe joint pain.
It was first described during an outbreak in southern Tanzania in 1952 and has now been reported in more than 110 countries in Asia, Africa, the Americas, and Europe.
The name “chikungunya” derives from a word in the Kimakonde language of southern Tanzania, meaning “that which bends up” and describes the stooped appearance of infected people with severe joint pain (arthralgia).

Chikungunya Transmission

It is transmitted to humans by the bites of infected female mosquitoes, most commonly Aedes aegypti and Aedes albopictus mosquitoes.
These two species can also transmit other viruses, including dengue and Zika viruses.
It is not transmitted from one person to another. (i.e., it is not a contagious disease).

Chikungunya Symptoms

In symptomatic patients, CHIKV disease onset is typically 4–8 days (range 2–12 days) after the bite of an infected mosquito.
The most common symptom is an abrupt onset of fever, often accompanied by joint pain.
Other symptoms include muscle pain, headache, nausea, fatigue, and rash.
Severe joint pain usually lasts a few days but can persist for months or even years.
Serious complications are uncommon, but atypical severe cases can cause long-term symptoms and even death, especially in older people and in children under one year old.

Chikungunya Treatment

There is no vaccine or antiviral drug treatment for chikungunya.
Treatment is focused on relieving the symptoms.
