Andriamamelo Cave : Rock Art Drawings

Unique, prehistoric rock art drawings have been discovered in the Andriamamelo Cave in western Madagascar.

  • Andriamamelo Cave is situated in the western Madagascar.
  • It is located in karstified limestone of the Paysage Harmonieux Protege de Beanka.
  • This is part of an extensive karst region that includes the Parc National de Bemaraha to the south, a UNESCO World Heritage site, and the little-studied Antsingimavo karst area to the north.

Key findings:

  • In this cave truly pictorial art, depicting images of nature with human-like and animal-like figures have been discovered.
  • The dramatic discoveries contained several surprises, including hints at some remarkable cultural connections.
  • First, scenes depicted in some cases linked up fairly directly to Egyptian religious motifs from the Ptolemaic period (300-30 BCE).
  • Second, other inferences from symbols and writing on the walls showed connections to the Ethiopian and Afro-Arab worlds.
  • Finally, prevalent symbology and motifs evoked a two-millennia-old cave art style from Borneo.
  • At least three extinct animals of Madagascar which was thought to have been extinct for many centuries may be depicted – a giant sloth lemur, elephant birds and a giant tortoise.
  • Egyptian connections are hinted at in eight major images, including a falcon (Horus); the bird-headed god Thoth; the ostrich goddess Ma`at and two human-animal figures which were similar to Anubis – an ancient Egyptian god usually depicted as a man with a canine head.

North Korea Test-Fired Solid-Fuel Missiles:

North Korea test-fired an Intercontinental Ballistic Missile (ICBM) powered by solid fuel.

  • Solid-fuel missiles do not need to be fuelled immediately ahead of launch.
  • They are often easier and safer to operate, and require less logistical support.
  • They are harder to detect and more survivable than liquid-fuel weapons.
  • Solid propellants are a mixture of fuel and oxidiser.
  • Metallic powders such as aluminium often serve as the fuel, and ammonium perchlorate, which is the salt of perchloric acid and ammonia, is the most common oxidiser.
  • The fuel and oxidiser are bound together by a hard rubbery material and packed into a metal casing.
  • When solid propellant burns, oxygen from the ammonium perchlorate combines with aluminium to generate enormous amounts of energy and temperatures of more than 5,000 degrees Fahrenheit (2,760 degrees Celsius), creating thrust and lifting the missile from the launch pad.

Blue Dragons : Spotted

Blue dragons (Glaucus atlanticus) have been spotted on the beach and in waters near the shore in Besant Nagar in Chennai.

  • The blue dragon (Glaucus atlanticus) is a type of mollusc known as a nudibranch.
  • They also are known as blue sea slugs, blue angels, and sea swallows.
  • It rarely grows larger than three centimetres long.
  • An air bubble stored in its stomach keeps the blue dragon afloat.
  • It can be found drifting on the surface of the Atlantic, Pacific and Indian oceans in temperate and tropical waters.
  • They feed on venomous siphonophores such as the Portuguese man-o-war and bluebottle, which also occur in ocean surface waters.
  • The dragons appear immune to the nematocysts stinging cells of these jellyfish-like creatures.
  • They incorporate these cells into multiple finger-like structures protruding from their body which provides them with a potent form of protection from predators.
  • The slug isn’t venomous all on its own, however, it stores the stinging nematocysts created by the creatures on which it feeds.
  • Its sting can cause problems, especially to children and elderly.
  • One sting from this little creature can lead to nausea, pain, vomiting, acute allergic contact dermatitis, and post-inflammatory hyperpigmentation.

Katabatic Winds:

A surprising phenomenon has been observed in the Himalayas, where ‘katabatic’ winds are triggered when high temperatures affect high-altitude ice masses.

  • This leads to cold air blowing to lower-altitude areas, potentially slowing down the effects of the global climate crisis in some regions.
  • The study reveals that a temperature gap between air above the mountains and cooler air in contact with ice masses causes increased turbulent heat exchange, leading to stronger cooling of the surface air mass.
  • Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column.
  • Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and create a downslope wind.

Earthquake In Northwestern China:

An earthquake in northwestern China killed at least 131 people.

  • At least 127 people have been killed and hundreds of others were injured after an overnight earthquake hit northwestern China in a remote and mountainous region while many were asleep at home.
  • The earthquake was the most deadly China has experienced in nine years.
  • An earthquake is the shaking or trembling of the earth’s surface.
  • It is caused by the seismic waves or earthquake waves that are generated due to a (sudden release of energy in the earth’s crust shallow-focus earthquakes or upper mantle some shallow-focus and all intermediate and deep-focus earthquakes.
  • Earthquake are by far the most unpredictable and highly distructive of all the natural disasters

Grass pea, also known as khesari dal, has been historically infamous for causing lathyrism, a neurological disease leading to lower limb paralysis.

  • In the late 19th century, an outbreak of lathyrism linked to grass pea led to its ban in India in 1961 under the Prevention of Food Adulteration Act.
  • Despite the ban, grass pea cultivation continued, and researchers developed low-toxin varieties.
  • In 2015, an expert committee recommended lifting the ban, emphasizing its potential for food security amid climate change.
