Miller-Urey Hypothesis

A study highlighted that ‘microlightning’ may have sparked life on Earth, challenging Miller-Urey Hypothesis. 

  • Microlightning is the tiny electric sparks (imitates how lightning forms in clouds) that form when oppositely charged water droplets come close together after splitting.

About Miller-Urey Hypothesis 

  • It claimed that lightning strikes triggered chemical reactions in Earth's early atmosphere. 
    • It successfully demonstrated that the organic compounds (such as amino acids) needed for life could form with the application of electricity to a mixture of water and inorganic gases.
    • Recent study has demonstrated formation of organic compounds using microlightning. 
  • Limitation: Critics argue that lightning strikes were rare and mostly occurred over the open ocean, where organic compounds would have quickly dispersed.

Autonomous Surface Vessels (ASVs)

Indian and US firms signed an MoU to co-develop Wave Glider, an Autonomous Surface Vessels (ASVs) for Anti-Submarine Warfare.

 About Autonomous Surface Vessels (ASVs)

  • These are robotic vehicles that operate on the sea surface, recording oceanographic data.
  • They use wave power or propeller-driven propulsion systems.
  • Advantages: 
    • Larger payloads and higher battery capacity compared to Autonomous Underwater Vehicles.
    • Utilize renewable energy sources such as solar and wind power for prolonged operations.
  • Challenges: Navigational risks in congested waters.

Sonic Weapon

Serbia denied using a banned 'sonic weapon’ to disperse protesters in Belgrade.

About Sonic Weapon

  • Also known as Acoustic weapons are devices that deliver very loud sounds over long distances. 
    • They can also be used to act like voice amplifiers to deliver voice messages/other sounds.
  • Working: Usually comprise hundreds of modern transducers, an electronic device that converts energy from one form to another to create highly concentrated and amplified sound, narrowing beams to focus on specific targeted areas. 
  • Impact: Tinnitus (perception of ringing, buzzing, or other sounds in ears without an external source); hearing loss etc.
