Al-Natah

Context:

Recently, Archaeologists have discovered a 4,000-year-old fortified town, Al-Natah in Saudi Arabia. 

About Al-Natah (in Saudi Arabia):

Location and Discovery: 

  • Discovered in northwest Saudi Arabia within the Khaybar oasis.
  • Discovered by French archaeologist Guillaume Charloux and his team.
  • The city was buried under layers of basalt rock for centuries.

Age and Timeline:

  • Dates back to approximately 2400 BCE (Early Bronze Age).
  • Inhabited until at least 1500 BCE, possibly until 1300 BCE.
  • Represents one of the earliest known urban settlements in the region.

Urban Layout:

  • Three distinct zones: Residential area, Decision-making zone and Necropolis (cemetery).
  • Town Features: Three-storey houses, Organized street network, Standardized building plans, Interconnected dwellings etc.
  • A Fortified Settlement: The town was protected by a massive 14.5-kilometre wall, showcasing its strategic importance.
  • A Thriving Civilization: Al-Natah was a significant urban centre, housing up to 500 residents during its peak.

Historical Significance:

  • It demonstrates the transition from nomadic to urban lifestyle and shows evidence of “slow urbanism” or “low urbanization”.
  • It is located between ancient Egyptian and Mesopotamian civilizations.
  • It served as a key trade hub.
  • Regional Impact: Changes the understanding of the Bronze Age in northwest Arabia.

PyPIM Platform

Context:

Recently, Israeli researchers have developed software that enables computers to process data directly in memory, bypassing the central processing unit (CPU).

About PyPIM Platform

  • Integration of Python & PIM: PyPIM combines the Python programming language with digital processing-in-memory (PIM) technology, enabling developers to write software for PIM-based systems. 
  • In-Memory Operations: It uses specialized instructions to perform computations directly within memory, bypassing the need to transfer data between memory and the CPU.
  • Solving the Memory Wall: The platform addresses the “memory wall” problem, where CPU performance outpaces the data transfer speeds between memory and processors.
  • Energy & Time Efficiency: By performing operations in memory, PyPIM significantly reduces the time and energy required for data transfers, which are typically a bottleneck in traditional computing.
  • Reduced CPU Dependency: This innovation minimizes the CPU’s role in data processing, leading to overall system performance improvements, especially in terms of speed and energy consumption.
  • Python-Based Development: PyPIM allows developers to leverage Python, a familiar language, to harness the power of PIM systems.

Chonkus

Context:

Recently, researchers at the Wyss Institute at Harvard University and the University of Palermo have discovered a new strain of cyanobacteria, Chonkus. 

About Chonkus:

  • Chonkus cells are significantly larger than other cyanobacteria due to carbon-dense granules.
  • Carbon Sequestration: These granules enable rapid sinking in water, allowing Chonkus to carry sequestered carbon to deeper ocean layers.
  • Growth Potential: In laboratory settings, it grows quickly, forming substantial colonies and thriving in carbon-rich environments.

Climate Change Mitigation Potential

  • Chonkus’s ability to absorb high levels of CO₂ makes it promising for natural carbon sequestration.
  • The sinking trait aids in transferring captured carbon to ocean depths, potentially reducing atmospheric CO₂.
  • This organism may serve in bio-manufacturing applications, creating eco-friendly, industrial carbon capture solutions.

About Cyanobacteria:

  • Cyanobacteria are ancient photosynthetic organisms at the base of marine food chains.
  • Name Origin: The name “cyanobacteria” refers to their bluish-green (cyan) colour, which also forms the basis of cyanobacteria’s informal name blue-green algae. Although as prokaryotes they are not scientifically classified as algae.
  • Known for their resilience, cyanobacteria survive in extreme conditions and are capable of rapid growth.
  • By converting CO₂ into biomass, they play a vital role in carbon cycling and oxygen production.
