- The Sugamya Bharat App is an initiative by the Department of Empowerment of Persons with Disabilities (DEPwD) under the Ministry of Social Justice and Empowerment. It is designed to assist people with disabilities and the elderly by enabling users to report accessibility issues in public infrastructure, transportation, and buildings.
- Objectives:
- Issue Identification: Users can report accessibility-related issues at public places, capturing the location using Google Maps.
- Geotagged Photos: The app allows users to upload geotagged images to help identify and understand accessibility problems in various types of public spaces.
- Complaint Registration: Individuals facing accessibility challenges in India can use the app to submit their concerns. Only issues related to buildings, transportation systems, and Information and Communication Technology (ICT) such as websites and TV viewing can be reported.
- Forwarding Complaints: Complaints submitted through the app are forwarded to the relevant authorities for resolution.
- Upcoming Enhancements:
- The government is planning to enhance the app by integrating AI technology.
- AI Features: The upgraded version will feature an AI-powered chatbot and a multilingual interface to improve functionality and user experience.
- Collaborations: The development of the AI-enabled app involves a partnership with the NGO Mission Accessibility and the research institute I-STEM.
- These upgrades aim to make the app more effective and accessible, providing better support for users with disabilities and the elderly.

- Researchers have recently discovered a new relative of turmeric, known as Curcuma ungmensis, following an unexpected find during a field expedition in Nagaland.
- Curcuma ungmensis:
- Classification: This new species belongs to the genus Curcuma within the ginger family, Zingiberaceae.
- Naming: The plant has been named Curcuma ungmensis after Ungma, the village in Mokokchung district where it was discovered.
- Botanical Characteristics: Curcuma ungmensis is a rhizomatous herb, meaning it has a branched rhizome (an underground stem) that grows deeply buried in the soil. It could potentially be introduced into gardens as an ornamental ground cover following appropriate cultivation.
- Flowering: The plant flowers during the rainy season from August to October. The blooms emerge in the morning and last for just one day.
- Threats:
- The species is under "severe threat" from several factors, including road construction, building development, and natural disasters.
- Genus Overview:
- Zingiberaceae Family: The Zingiberaceae family comprises 21 genera and around 200 species in India.
- Curcuma Genus: Curcuma is one of the largest and most significant genera in this family. Notable species include turmeric (Curcuma longa), black turmeric (Curcuma caesia), and mango ginger (Curcuma amada).
- Distribution: Curcuma is found widely across South and Southeast Asia and southern China, with some species also in northern Australia and the South Pacific. In India, about 40 species of Curcuma are present, predominantly in the northeastern and southern states, as well as the Andaman and Nicobar Islands.
- Recently, the BepiColombo spacecraft provided scientists with their first detailed view of Mercury’s south pole.
- About the BepiColombo Spacecraft:
- Mission Overview: BepiColombo is a collaborative mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), dedicated to exploring Mercury.
- Naming: The spacecraft is named after Giuseppe "Bepi" Colombo, an Italian mathematician and engineer renowned for his work on Mercury's orbit.
- Launch: It was launched on October 20, 2018. The mission is notable for its ambitious and intricate objectives, focusing on studying Mercury’s surface, composition, magnetic field, and its interactions with the solar environment.
- Components: The BepiColombo spacecraft comprises two main modules:
- Mercury Planetary Orbiter (MPO): Supplied by ESA, the MPO is tasked with mapping Mercury’s surface, analyzing its composition, and studying its topography.
- Mercury Magnetospheric Orbiter (MMO): Provided by JAXA, the MMO is dedicated to investigating Mercury’s magnetic field and magnetosphere.
- Objectives:
- Surface and Composition Analysis: To explore Mercury’s surface and composition in order to gain a deeper understanding of its geological history and formation processes.
- Magnetic Field and Magnetosphere: To examine Mercury’s magnetic field and magnetosphere, providing insights into its internal structure and its interactions with the solar wind.
- Exosphere Study: To measure and analyze Mercury’s exosphere (a very thin atmosphere) and understand its composition and dynamics.
Relativity Experiments: To conduct experiments aimed at testing principles of general relativity and enhancing our knowledge of gravity.
- Recently, a doctor based in Bengaluru reported a noticeable increase in cases of Kawasaki disease among children following the severe second wave of COVID-19.
- About Kawasaki Disease:
- Alternate Names: Kawasaki disease is also referred to as Kawasaki syndrome or mucocutaneous lymph node syndrome.
- Description: This rare condition primarily affects children under the age of 5. It is characterized by fever and inflammation of the blood vessels.
- Prevalence: It is one of the most common forms of acquired heart disease in children. The disease leads to the immune system attacking the blood vessels, causing inflammation and swelling.
- Affected Areas: Kawasaki disease predominantly impacts the coronary arteries, which supply blood to the heart muscle. It can also affect lymph nodes, the skin, and the mucous membranes of the mouth, nose, and throat.
- Symptoms: Key symptoms include prolonged fever, rash, swelling of the hands and feet, redness of the eyes, swollen lymph nodes in the neck, and inflammation of the mouth, lips, and throat.
- Historical Background: The disease was first identified in Japan by Tomisaku Kawasaki in 1967. The first cases reported outside Japan were in Hawaii in 1976.
- Cause: The exact cause of Kawasaki disease remains unknown, though it appears to be more common during late winter and early spring.
