  • Wildlife officials in Assam reported that a team of herpetologists recently discovered the striped caecilian (Ichthyophis spp) for the first time in Kaziranga National Park and Tiger Reserve during a rapid survey of the area.
  • Here are some facts about Caecilians:
    • Caecilians are elongated, segmented, limbless amphibians classified in the order Gymnophiona or Apoda ("without legs").
    • They belong to the same group as frogs and salamanders.
    • Due to their lack of limbs, caecilians resemble earthworms or snakes in appearance.
    • The name "Caecilian" means "blind"; some species are eyeless, while others have small eyes hidden under their skin.
    • There are approximately 200 known species of caecilians.
  • Habitat:
    • Most caecilians inhabit moist tropical and subtropical regions in South and Central America, South and Southeast Asia, and Sub-Saharan Africa.
    • They are primarily terrestrial and spend much of their lives underground.
    • Caecilians burrow in forests, grasslands, savannas, shrublands, and wetlands.
  • Other Features:
    • Smaller caecilians measure less than three inches, while the largest species (such as Caecilia thompsoni from Colombia) can grow to almost five feet long.
    • They have a hard, thick skull with a pointed snout that helps them move effectively through dirt or mud.
    • Their shiny skin is ringed with folds called annuli and typically comes in shades of gray, brown, black, orange, or yellow.
    • Some species have tiny, fishlike scales within these rings.
    • Caecilians have short, sensory tentacles located between their eyes and nostrils that assist in exploring their environment and finding prey.

  • A team from the Indraprastha Institute of Information Technology, Delhi (IIIT-Delhi), has achieved joint second place in Trinity Challenge’s latest competition focused on combating the growing threat of antimicrobial resistance (AMR).
  • Here's an overview of The Trinity Challenge (TTC):
    • TTC is a charitable initiative dedicated to fostering data-driven solutions that safeguard against global health crises.
    • It operates through a coalition of more than 40 prominent organizations spanning private, public, and social sectors.
    • The partnership aims to leverage data and advanced analytics to drive inclusive innovations and enhance global readiness for health emergencies.
    • Launched in response to the Covid-19 pandemic, TTC's inaugural challenge sought innovations in data-driven approaches to predict, respond to, and recover from pandemics.
    • The initiative awarded £5.7 million to teams pioneering tools and strategies for improved pandemic preparedness and response.
    • Building on this success, the second Trinity Challenge focused on addressing antimicrobial resistance (AMR), calling upon the world's top minds to develop data-driven solutions preserving the efficacy of antibiotics.
    • IIIT-Delhi's project, titled 'AMRSense: Empowering Communities with a Proactive One Health Ecosystem,' led by IIIT-Delhi in collaboration with CHRI-PATH, 1mg.com, and ICMR, stands out in the second challenge:
    • 'AMRSense' tackles the complexities of engaging, motivating, and training community health workers (CHWs) in AMR surveillance and management.
    • It addresses the absence of a comprehensive data ecosystem and analytics capabilities crucial for effective AMR management.

  • The Maharashtra government faced criticism from the Bombay High Court recently for its inadequate implementation of mechanisms, including the absence of a proper medical board, to enforce living wills.
  • Here's an overview of Living Wills:
    • A Living Will, also known as an Advance Medical Directive, outlines a person's preferences for medical treatment in case they are unable to communicate or make decisions due to unconsciousness or coma.
  • Legality of Living Will in India:
    • Until 2018, living wills were not legally recognized in India.
    • However, in the landmark case of Common Cause vs. Union of India (2018), the Supreme Court acknowledged the validity of advance medical directives, allowing terminally ill patients or those in a persistent vegetative state to refuse medical treatment, thus sanctioning passive euthanasia.
  • Who Can Draft an Advance Medical Directive/Living Will?
    • An adult of sound mind who comprehends the purpose and implications of the document can create a living will.
    • The decision must be voluntary and clearly articulated.
  • Elements of a Living Will:
    • It must be written and explicitly state under what conditions medical treatment may be withheld or if specific treatments delaying death should be administered.
    • Instructions should be unambiguous and clear.
    • The document should specify whether the patient can revoke the directive and designate a guardian or close relative authorized to make medical decisions if the patient becomes incapable.
  • Recording of Living Will:
    • The living will must be signed by the patient in the presence of two witnesses, preferably independent.
    • It should be countersigned by a Judicial Magistrate First Class (JMFC) designated by the district judge, who ensures copies are distributed to relevant authorities and family members of the executor.

  • Researchers have identified a new genus of Gomphonemoid diatom thriving in the pristine rivers of the Eastern Ghats, naming it Indiconema to honor its restricted distribution within India.
  • Characteristics of Gomphonemoid Diatoms:
    • These organisms are photosynthetic, single-celled algae crucial to the aquatic food web.
    • They are microscopic and exceptionally sensitive to changes in water chemistry, making them valuable indicators of aquatic ecosystem health.
    • Gomphonemoid diatoms are widespread in both freshwater and marine environments, constituting a significant portion of phytoplankton.
  • Unique Features of Indiconema:
    • Indiconema sets itself apart by possessing pore fields at both the head and foot poles, a distinction from related species.
    • Researchers have documented one species of Indiconema in the Eastern Ghats and another in the Western Ghats, mirroring patterns observed in other endemic-rich groups like reptiles across these mountain systems.
    • Morphologically, Indiconema shows similarities to Afrocymbella, a genus native to East Africa, suggesting a close evolutionary relationship.
  • Importance:
    • Diatoms, with their silica-based cell walls and distinct frustule patterns, play a vital role in global oxygen production, contributing up to 50% annually.
    • The discovery of Indiconema underscores the ecological richness of India's water bodies and highlights the Eastern Ghats as a haven for unique and often endemic aquatic species.

  • In a significant milestone for global health, Chad has achieved a monumental feat in 2024 by becoming the first country of the year and the 51st worldwide to eliminate the gambiense form of human African trypanosomiasis (HAT), also known as sleeping sickness.
  • Key Details about Human African Trypanosomiasis (HAT):
    • HAT is caused by protozoan parasites transmitted by infected tsetse flies, primarily found in sub-Saharan Africa.
  • There are two forms of the disease:
    • Trypanosoma brucei gambiense: Found in West and Central Africa, this form accounts for 92% of reported cases and leads to a chronic illness. Symptoms may not appear for months or years, often with the central nervous system already affected when symptoms become evident.
    • Trypanosoma brucei rhodesiense: Found in Eastern and Southern Africa, this form causes an acute illness with symptoms emerging within weeks to months after infection, progressing rapidly with invasion of multiple organs, including the brain.
  • Tsetse flies, endemic to sub-Saharan Africa, are the vectors responsible for transmitting the disease. Rural populations engaged in agriculture, fishing, animal husbandry, or hunting are at the highest risk of exposure.
  • Achievements in Elimination:
    • Chad's achievement marks the seventh country where the World Health Organization (WHO) has validated the elimination of the gambiense form of HAT. Previous validations include Togo (2020), Benin (2021), Ivory Coast (2021), Uganda (2022), Equatorial Guinea (2022), and Ghana (2023).
    • This milestone underscores Chad's commitment to public health and reflects global efforts to combat neglected tropical diseases, paving the way for improved health outcomes in the region and beyond.
