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.
