Neutrinos

Recently, researchers have detected High-energy cosmic neutrinos under Mediterranean Sea.

About Neutrinos

  • Nature: Subatomic particles (often called as ghost particles) that have zero electrical charge, zero size, almost zero mass and almost zero interaction.
  • Occurrence:  Second-most abundant particles after photons (particles of light) and most abundant among particles found in universe.  
  • Detectability: Difficult to detect as they only interacts with matter via weak nuclear force
  • Feature: Undisturbed by even the strongest magnetic field; Travel in straight lines from their source etc.

Project Waterworth

Meta has introduced its world’s longest undersea cable system - Project Waterworth.

About Project Waterworth

  • Length: 50,000 km subsea cable will connect five continents, enhancing connectivity between U.S., India, Brazil, South Africa, and other regions.
  • Depth: Cable will reach depths of up to 7,000 meters in deep waters.
  • Techniques: Enhanced burial methods will be used in high-risk areas, like shallow coastal waters, to protect cable from ship anchors and other hazards.
  • Significance: 
    • Strengthen scale and reliability of world’s digital highways by opening three new oceanic corridors with high speed connectivity. 
    • Facilitate greater economic cooperation, digital inclusion etc.

Ovoid cells

Researchers have discovered a new type of brain cells, named Ovoid cells.

About Ovoid cells

  • Type of neuron that plays a fundamental role in recognition memory — the process by which the brain differentiates between new and familiar objects and forms long-term memories.
  • Ovoid cells, named for their distinct egg-like shape, are present within the hippocampus of humans, mice, and other animals. 
  • These cells activate whenever we encounter something new, triggering a process that stores objects in memory.
  • Finding could aid in the treatment of brain conditions related to object recognition, such as Alzheimer’s disease, Autism Spectrum Disorder, and Epilepsy.
