2. VB_HmeY_H4907
At the lowest point, nearly 11,000 metres below the surface of the Pacific Ocean, a new virus named vB_HmeY_H4907 has been discovered on Earth.

About VB_HmeY_H4907:

  • It is a new virus discovered nearly 11,000 metres below the surface of the Pacific Ocean.
  • The virus has been understood as a Bacteriophage, which means ‘bacteria eater’.
  • It infects halophilic bacteria (bacteria that inhabit environments with high salt concentrations) from the genus Halomonas. Such bacteria are generally found in deep-sea hydrothermal vents.
  • The virus is actually very genetically similar to its host and is a lysogenic phage, meaning that it inserts its genetic material into the bacteria but usually doesn’t kill it; instead, both virus and bacteria replicate at the same time.

What are Bacteriophages?

  • Bacteriophages, also known as phages, are viruses that infect and replicate in bacterial cells. 
  • They also infect the single-celled prokaryotic organisms known as archaea.
  • They were discovered independently by Frederick W. Twort in Great Britain (1915) and Félix d’Hérelle in France (1917). 
  • They are ubiquitous in the environment and are recognised as the most abundant biological agent on earth.
  • They are extremely diverse in size, morphology, and genomic organisation.
  • Like all viruses, phages are simple organisms that consist of a core of genetic material (nucleic acid) surrounded by a protein capsid. The nucleic acid may be either DNA or RNA and may be double-stranded or single-stranded.
3. I2U2 Group
The I2U2 group recently announced a new joint space venture that aims to create a "unique space-based tool" for policymakers, institutions, and entrepreneurs.

About the I2U2 Group:

  • It is a grouping of India, Israel, the United Arab Emirates, and the United States.
  • Formation:
    • The group was initially formed in October 2021 to deal with issues concerning infrastructure, transport, and maritime security in the region.
    • Originally named the "International Forum for Economic Cooperation," it was also known as the "West Asian Quad" at the time.
    • First virtual summit: The group held their first virtual summit in July 2022.
  • This unique grouping of countries identifies bankable projects and initiatives to tackle some of the greatest challenges, with a particular focus on joint investments and new initiatives in water, energy, transportation, space, health, food security, and technology. 
  • It aims to mobilise private sector capital and expertise to achieve a variety of goals, including modernising infrastructure, advancing low-carbon development pathways, and improving public health. 
4. Foot and Mouth Disease (FMD)
The Chandigarh administration recently vaccinated over 21,000 livestock against foot and mouth disease (FMD).

About the Foot and Mouth Disease (FMD):

  • It is a highly contagious viral disease that affects cloven-hoofed animals, including cattle, sheep, goats, and pigs.
  • It is a transboundary animal disease (TAD) that deeply affects the production of livestock and disrupts regional and international trade in animals and animal products. 
  • It is a disease of animals, not humans and is a different disease than hand, foot, and mouth disease, which is common in young children.
  • Causative agent: It is caused by the foot-and-mouth disease virus, which is a member of the Picornaviridae family.
  • Transmission:
    • It is primarily spread through direct contact between infected animals, as well as through contaminated feed, equipment, vehicles, clothing, and the movement of infected animals.
    • It can be transmitted to humans in rare cases. Human cases are typically mild and self-limiting, with symptoms similar to other viral illnesses.
  • Symptoms: Common symptoms in affected animals include fever, blister-like sores on the tongue, lips, and inside the mouth, as well as on the hooves (hence the name "foot and mouth" disease), excessive salivation, lameness, and reduced milk or meat production.
  • Treatment:
    • Vaccination is a common method of control for FMD in regions where the disease is endemic or where there is a high risk of outbreaks.
    • Vaccinated animals can still contract the virus, but the disease's severity is reduced.
5. Hirakud Dam
A day after opening six gates of the Hirakud dam, the authorities opened 16 more sluice gates to discharge excess water from the reservoir.

About Hirakud Dam:

  • Hirakud Dam is built across the Mahanadi River, about 15 kilometres from Sambalpur in the state of Odisha.
  • It is the longest earthen dam in the world, about 16 miles and around 26 km in length.
  • The dam forms a vast reservoir known as the Hirakud Reservoir or Hirakud Lake. It is the biggest artificial lake in Asia.
  • History:
    • It is one of the first multipurpose projects undertaken by India after independence.
    • The construction began in 1948 and was completed in 1953.
    • It was built to control the flow of the Mahanadi River and manage the perennial problem of floods in the region.
    • The inauguration of the dam was done by the then Prime Minister Jawaharlal Nehru in 1957.
  • Purpose:
    • Irrigation facility to 1,08,385 hectares of Rabi crops and 1,55,635 hectares of Kharif crops in Bolangir, Subarnapur, Bargarh, and Sambalpur.

    • More than 436,000 hectares of land in the Mahanadi delta also get irrigated by the water which is released from the powerhouse. 
    • The delta area in Cuttack and Puri districts, which covers an area of 9500 sq Km, also gets flood protection because of the Hirakud Project. 
  • Structure:
    • Granite, hard concrete, and earth are the most used substances in building the dam.
    • Stretched from the Chandidungri hills on the right to the Lamdungri hills on the left, the main structure of Hirakud Dam is about 4.8 km long. 
    • About 83400 sq. km. is the catchment area, and the dam is a composite structure of Concrete, Masonry and Earth.
  • Cattle Island:
    • It is a small island in the Hirakud Reservoir.
    • It is inhabited by a large herd of wild cattle, which are believed to be the descendants of cattle that were left behind by villagers when the dam was constructed in the 1950s.

8. Plankton
Marine scientists say some areas in the Gulf of Thailand have more than 10 times the normal amount of plankton, turning the water a bright green and killing off marine life.

About Plankton:

  • The word “plankton” comes from the Greek for “drifter” or “wanderer.”
  • An organism is considered plankton if it is carried by tides and currents and cannot swim well enough to move against these forces. 
  • The most basic categories divide plankton into two groups: phytoplankton (plants) and zooplankton (animals).
  • Phytoplankton are microscopic plants, but they play a huge role in the marine food web.
  • Like plants on land, phytoplankton perform photosynthesis to convert the sun’s rays into energy to support them, and they take in carbon dioxide and produce oxygen.
  • Zooplankton includes microscopic animals (krill, sea snails, pelagic worms, etc.), the young of larger invertebrates and fish, and weak swimmers like jellyfish. Most zooplankton eat phytoplankton.

What is Plankton bloom?

  • Phytoplankton population explosion occurs when sunlight and nutrients are abundantly available to the plants.
  • They grow and reproduce to a point where they are so dense that their presence changes the colour of the water in which they live.
  • Blooms can be quick events that begin and end within a few days, or they may last several weeks. 
  • These plants grow so dense that it changes the colour of the water they live in.

Key Facts about the Gulf Of Thailand

  • It is a shallow inlet of the South China Sea located in the western part of the Pacific Ocean.
  • It is surrounded by the countries of Thailand, Cambodia, and Vietnam.
  • The gulf was formerly known as the Gulf of Siam, and in the modern Thai language, the Gulf is referred to as Ao Thai (“Thai Gulf”).
