IL-35-Mediated Immunotherapy

Why in news?

  • Researchers  from the Institute of Advanced Study in Science and Technology (IASST) in Guwahati,have discovered a specific protein IL-35.

How it works?

  • It protects the immune system by lowering particular immune cells that produce inflammatory chemicals, thereby reducing pancreatic cell infiltration, a key contributor in type 1 diabetes and autoimmune diabetes mellitus.
  • This protein presents a novel diabetes treatment option.
  • The growing global diabetes epidemic that disproportionately affects developing country children and adolescents calls for effective treatment for the disease.
  • IL-35, a specific protein of IL-12α and IL-27β chains, encoded by the IL12A and EBI3 genes. This finding has piqued scientists' interest, especially considering the Novel type 1 and autoimmune diabetes therapy may depend on IL-35, according to research.

What  is Diabetes ?

  • Diabetes is a metabolic disease that causes high levels of blood glucose, or blood sugar. Over time, this can lead to serious damage to the heart, blood vessels, eyes, kidneys, and nerves.

2. Scientists have discovered a “black hole triple” in space for the first time.

 “Black Hole Triple” System

 Why in news:

  • A new study says scientists have discovered a “black hole triple” in space for the first time.

 What is “black hole triple”

  • The system comprises a black hole at its centre, currently in the process of consuming a small star spiraling very close to it.
  • There is also a second star, which appears to be circling the black hole but is actually far away.

Important points:

  • The discovery of the system, located about 8,000 light years away from Earth has raised questions about how black holes are formed.
  •  black holes discovered until now have been part of binary systems, consisting of a black hole and a secondary object (such as a star or another black hole).
  • But the black hole triple not only has one star which orbits the black hole about every 6.5 days, but also a more far-off star which orbits it every 70,000 years.
  • It is situated in the constellation of Cygnus, the system features one of the oldest known black holes, the V404 Cygni, which is nine times as big as the Sun in our solar system.
  • V404 Cygni has two stars around it as the black hole did not arise from a supernova, which typically kicks away outer stars in the explosion.
  • Instead, it was formed through another process called “direct collapse”, where the star caves in after expending all its fuel, but does not explode.

Tags: Science and Technology

 India's first analog space mission:

Why in news:

  • Indian Space Research Organisation (ISRO) has started the country's first analog space mission at Leh in Ladakh, where the space agency will simulate life in an interplanetary habitat. 

What is the Purpose ?

  • The mission's goals were to study the physical and mental challenges of humans in space, test life support systems, and develop strategies for long-duration space missions. 
  • The mission took place in Leh, Ladakh, which was chosen because its geographical features closely resemble those of Mars and the Moon. 
  • Duration of the mission will be  one month. 
  • The mission used a compact, inflatable habitat called Hab-1, which was equipped with a hydroponics farm, kitchen, and sanitation facilities. 

Collaboration:

  • The mission was a collaboration between the Indian Space Research Organisation (ISRO), AAKA Space Studio, the University of Ladakh, IIT Bombay, and the Ladakh Autonomous Hill Development Council. 
  • The move assumes significance as India is planning to send a human to the Moon in the near future.

About ISRO:

  • The Indian Space Research Organisation (ISRO) is India's national space agency that specializes in space exploration, aerospace technology, engineering, and science.
  •  ISRO was established in 1969 to replace the Indian National Committee for Space Research (INCOSPAR). The agency's headquarters are in Bengaluru, India.

India has conducted its inaugural study on 'teal carbon' at Keoladeo National Park (KNP) in Rajasthan’s Bharatpur district.

An Overview of the News

  • Teal carbon refers to carbon stored in non-tidal freshwater wetlands, including carbon in vegetation, microbial biomass, and organic matter.

  • These wetlands serve as natural carbon sinks, crucial for regulating greenhouse gases, but are vulnerable to degradation from pollution, land-use changes, and water extraction.

Study Objectives

  • Estimate the carbon storage capacity of non-tidal freshwater wetlands in India.

  • Identify critical threats to these wetland ecosystems and their carbon sequestration potential.

  • Provide recommendations for wetland conservation and restoration.

  • Raise public awareness about the role of wetlands in climate change mitigation.

Importance of Wetlands

  • Wetlands offer essential ecosystem services such as water purification, flood control, and wildlife habitat.

  • Their carbon sequestration potential is significant, making their conservation vital for ecological balance and climate resilience.

Threats and Challenges

  • Wetlands face threats from urbanization, agricultural expansion, and pollution.

  • Addressing these threats requires a multi-pronged approach, including scientific research, policy interventions, and community engagement.

Keoladeo National Park
