Context: A preliminary investigation of the Nepal Yeti Airlines crash has found that propellers of the plane were found in an unusual “feathered” position.

About Feathering

  • When engines experience failure in mid-air, the pilot flying variable-pitch propellers can change the pitch/ angle of the propeller blades so that they slice the airflow in a more or less parallel motion.
  • This reduces the ‘drag’ and increases the gliding distance, preventing airspeed from falling below unsafe limits. This is known as ‘feathering’ of propellers.
  • In case feathering is not used, the wind hitting the aircraft’s powerless propellers causes windmilling, which increases gliding resistance.
  • Feathering is part of the checklist if the crew of an aircraft, facing emergency, is planning a forced landing.
  • Significance: Feathering significantly reduces drag, giving the aircraft valuable extra landing distance, when engines have lost power.
  • Drawbacks: Feathering can only be used by aircraft with variable-pitch propellers.


Hallucinating Chatbots

Context: Recently, Google has cautioned against ‘hallucinating’ chatbots.

About ‘Hallucinating’ Chatbots

  • Hallucination in AI chatbots is when a machine provides convincing but completely made-up answers,
  • It is not a new phenomenon and developers have warned of AI models being convinced of completely untrue facts, responding to queries with madeup answers.
  • In 2022, Meta released their AI conversational chatbot called BlenderBot 3.
  • BlenderBot 3 was capable of searching the internet to chat with users about any topic and would learn to improve its skills and safety through feedback from users.
  • However, Meta engineers had warned that the chatbot should not be relied upon for factual information and that the bot could apparently “hallucinate”.

How AI chatbots start hallucinating

  • Hallucinations can occur because these models require the capability to rephrase, summarise and present intricate tracts of text without constraints.
    • This raises the problem of facts not being sacred and they can be treated in contextual form when sifting through information.
  • An AI chatbot could possibly take widely available information rather than factual information as an input.
  • The problem becomes especially acute when complex grammar or arcane source material is used.
  • Therefore, AI models can start presenting and even believing in ideas or information that may be incorrect but which are fed to them by a large number of user inputs.


Mammatus Clouds

Context: The meteorological office of the UK, recently explained that Mammatus clouds are among the most extraordinary and easily recognizable cloud formations.

About Mammatus clouds

  • Mammatus clouds are some of the most unusual and distinctive cloud formations, with a series of bulges or pouches emerging from the base of a cloud.
  • Formation: They are usually formed in association with large cumulonimbus clouds.
    • Typically, turbulence within the cumulonimbus cloud will cause mammatus to form, especially on the underside of the projecting anvil as it rapidly descends to lower levels.
    • This reverses the usual cloud-forming process of upward growth, making for an uneven cloud base.
  • They have also been known to form on other cloud types, such as stratocumulus, altostratus and altocumulus and even along the underside of volcanic ash clouds.
  • Effects: These clouds bring thunderstorms due to their huge mass of unstable air, along with hail, heavy rain and lightning in the vicinity.

Nano DAP

Context: Agriculture ministry has approved the commercial release of Nano-DAP.

About Nano DAP

  • Urea and Di-Ammonium Phosphate (DAP) are largely consumed fertilizers in the country. IFFCO has received the patent for their nano variants from the Indian government for a period of 20 years.
  • Nano-DAP will be manufactured by India Farmers Fertilizer Cooperative (IFFCO) and Coromandel International.
  • 500-ml bottles of nano-DAP will have the same effectiveness of a bag (1350 kg) of conventional soil nutrient.
  • Benefits: It will help India save foreign exchange and also reduce government subsidy significantly.
    • Nano-DAP will be instrumental in reducing soil, air, and water pollution.

Nano Fertilizer

  • Nano Fertilizers hold great promise for application in plant nourishment because of the size-dependent qualities, high surface-volume ratio and unique optical properties.
  • Nano fertilizer releases plant nutrients in a controlled manner contributing to higher nutrient use efficiency.
