About Malaria:

• It is a life-threatening febrile illness caused by Plasmodium parasites.
• Transmission: It is transmitted through the bites of infected female Anopheles mosquitoes.
• It is not contagious, but can be spread through infected blood or contaminated needles.
• Risk: Infants, children under 5 years, pregnant women and girls, travellers and people with HIV or AIDS are at higher risk of severe infection.

  • Primaquine to prevent relapses in P. vivax and P. ovale infections.

About Magnetar:

• Magnetars are neutron stars having an ultrahigh magnetic field that are much stronger than the terrestrial magnetic field.
• They are formed in the same way as all neutron stars, through the core-collapse of a massive star in a supernova explosion.
• The idea of a magnetar was first proposed in 1987 and used to successfully explain soft gamma repeaters (SGR) in 1992. 
• Characteristics:
  • They are characterised by exceptionally strong magnetic fields, estimated to be a thousand times stronger than typical neutron stars.
  • The magnetic field of a magnetar is over one quadrillion times stronger than the magnetic field of Earth.
  • What powers the emission of high-energy electromagnetic radiation in them is the decay of magnetic fields in these objects.
  • Besides, magnetars display strong temporal variability, typically including a slow rotation, a rapid spin-down, bright but short bursts going on upto months-long outbursts.
  • Occasionally, they emit intense bursts of energy in the form of flares.

About Kamlang Tiger Reserve:

• Location: It is located in Arunachal Pradesh near the border with Myanmar.
• It is a part of the larger Eastern Himalayan Biodiversity Hot Spot.
• It is named after the Kamlang River, which flows through the reserve and joins the Brahmaputra.
• It is spread between the famed Namdapha National Park on its south and the Lang River on its north.
• The western border is formed by the Lati River, while its eastern part is bordered by the Tawe River.
• Topography: It encompasses a diverse range of landscapes, including dense tropical forests, grasslands, rivers, and hills.
• Climate: It enjoys a subtropical climate as it falls within the subtropical zone.
• Vegetation: The vegetation types include moist evergreen tropical forests in the foothills and subtropical and temperate forests in higher elevations.
• Flora: Common species of trees in the reserve include Ammora wallichi (Amari), Gmelina arborea (Gamari), Terminalia chebula (Hillika), Canarium resigniferum (Dhuna), and many others.
• Fauna: All four big cats, including the Snow Leopard, Clouded Leopard, Leopard and Tiger and other species like Himalayan Palm Civets, Leopard Cat, Slow Lories and Hoolock Gibbon, can also be spotted in the sanctuary.

About Hanging Glaciers:

• Hanging glaciers are ice masses perched on steep slopes that can detach and trigger massive avalanches.
• Formation:
  • They occur when a major valley glacier system retreats and thins, leaving the tributary glaciers in smaller valleys high above the shrunken central glacier surface.
  • If the entire system has melted and disappeared, the empty high valleys are called hanging valleys.
• Impact of Hanging Glaciers:
  • Hanging glaciers pose a significant risk of break-offs.
  • The break-offs from hanging glaciers can also trigger secondary hazards such as glacial lake outburst floods (GLOFs).
  • Glaciers in high-elevation alpine environments are highly sensitive to climate variability and warming.
  • This sensitivity is particularly pronounced in the Himalaya, where warming over the past two decades has exceeded the global average, resulting in accelerated glacier retreat.

About Larak Island:

• Location: It is a small island located in the Strait of Hormuz.
• It is to the south of Hormuz Island, southeast of Bandar Abbas and southeast of the eastern end of Qeshm Island.
• The island sits close to one of the world's most important maritime choke points.
• Larak's importance is closely tied to the Strait of Hormuz, the narrow waterway linking the Persian Gulf with the Gulf of Oman.

Key Facts about Strait of Hormuz:

• It is a narrow waterway between Iran and the Arabian Peninsula, specifically the United Arab Emirates, and Musandam (Oman).
• The Gulf of Oman is on the strait’s east, while the Persian Gulf is on the west.
• It is the only sea channel linking the oil-rich Persian Gulf (west) with the Gulf of Oman and the Arabian Sea (southeast).
• Iran is located on the north coast, while the UAE is on the south coast. 
• Islands: Some of the islands located in the Strait of Hormuz are Hengam, Hormuz, and Qishm.

About Rove beetle:

• Rove beetles (family Staphylinidae) are one of the largest beetle families.
• Appearance: They are typically elongate, fast-moving beetles with shortened wing covers (elytra) that expose flexible abdominal segments.
  • Many species of these beetles can raise the abdomen in a scorpion-like defensive posture (not a true sting).
• Preferred climate: It is mainly found in sub-tropical, cold tolerant climate.
• Habitat: Typical microhabitats include leaf litter, soil surface, under bark, fungi, shorelines, dung, carrion, compost, and nests of social insects;
• Diet: These are usually found around decaying animal and vegetable matter, preying on carrion-feeding insects. 
• Distribution: Rove beetles occupy almost all moist environments throughout the world.
• Features:
  • Some large species are a brightly coloured black and yellow, thus resembling wasps; other rove beetles mimic soldier ants in both appearance and behaviour.
  • These predatory beetles are beneficial to farmers and gardeners, because they can reduce pest populations, also referred to as biological control
  • Lifespan is variable: Adults may live ~2 weeks to ~12 months; total life cycle often ~1-24 months depending on climate and species.
  • It has chemical defenses from abdominal glands; secretions can deter predators and may include irritants or antimicrobial compounds.

About Solar Flare:

• A solar flare is a tremendous explosion on the Sun that happens when energy stored in 'twisted' magnetic fields (usually above sunspots) is suddenly released.
• A flare appears as a sudden, intense brightening of a region on the Sun, lasting several minutes to hours.
• Flares occur when intense magnetic fields on the Sun become too tangled. 
• In a matter of just a few minutes, they heat the material to many millions of degrees and produce a burst of radiation across the electromagnetic spectrum, including from radio waves to x-rays and gamma rays.
• The biggest flares occur in association with large sunspots that have sharp magnetic gradients and large currents, which are the source of the flare energy.
• There are five different classes of solar flares: A, B, C, M, and X;
  • X-class flares: These are the biggest; they are major events that can trigger radio blackouts around the whole world and long-lasting radiation storms in the upper atmosphere.
  • M-class flares: These are medium-sized; they generally cause brief radio blackouts that affect Earth's Polar Regions. Minor radiation storms sometimes follow an M-class flare.
  • C-class flares: These are small with few noticeable consequences here on Earth. At its peak, a C-class flare is ten times less powerful than an M-class flare.
  • B-class flares: These are ten times smaller or weaker than C-class flares.
  • A-class flares: These are at least ten times less intense than B-class flares, with no noticeable consequences on Earth.
• Effect of Solar Flare on Earth:
  • The intense radiation emitted during a solar flare can affect satellite communications, disrupt radio signals, and even pose a risk to astronauts in space.
  • Additionally, the increased solar radiation can lead to geomagnetic storms, which may impact power grids and cause auroras (northern and southern lights) at lower latitudes.
