Sciencedata-centre-cooling

Google, TCS, and the physics of air-cooling a large data centre | Explained

Google reportedly plans air cooling for a 1-GW Visakhapatnam data centre, but the article says air cooling alone is impractical at that scale. Modern AI racks can emit 120–150 kW against an air-cooling limit near 40 kW, making hybrid systems with direct liquid cooling more suitable for high-density clusters.

Prelims pointers

  • A 1-GW data centre would in principle have to remove 1 GW of heat if the full power rating applies to the facility itself.
  • Liquid-cooled facilities are estimated to carry a 7–10% project-cost premium for piping, leak detection and coolant-distribution equipment.
  • The article places air cooling’s thermal limit near 40 kW per rack, while Nvidia Blackwell-based racks can emit 120–150 kW.
  • Hybrid 1-GW designs use air cooling for low-density loads and direct-to-chip liquid cooling for high-density AI clusters.
  • Google said it would replenish 120% of water consumed for non-cooling operational needs by 2030.

  • The Daniel K. Inouye Solar Telescope used a four-metre primary mirror to observe the active region NOAA 14060.
  • Processed solar images covered 5,800 km by 4,350 km and achieved a spatial resolution of 19 km.
  • Plasma coils along granule boundaries measured about 25-170 km in length and were separated by roughly 65 km.
  • The fastest vortices grew to 2.7 times their original size in 18 seconds; the observed vortices rotated at about 1.6-2.8 km per second.

Geographymap-projections

What’s the issue with the way Africa is shown on maps? | Explained

The African Union endorsed the Correct the Map campaign, which favours equal-area alternatives such as Equal Earth over the Mercator projection. Mercator preserves local shapes and angles for navigation but greatly inflates high-latitude regions and diminishes equatorial landmasses, including Africa.

Prelims pointers

  • Gerardus Mercator designed the Mercator projection in 1569 to make fixed-compass rhumb-line courses easier to plot for navigation.
  • Mercator is conformal: it preserves local shapes and angles but enlarges high-latitude landmasses and diminishes equatorial regions.
  • Africa covers about 30 million sq. km but can appear similar to Greenland on Mercator maps although Greenland is 14 times smaller.
  • Equal Earth was created in 2018 by Tom Patterson, Bojan Šavrič and Bernhard Jenny and preserves relative area while altering shapes.
  • The African Union endorsed the Correct the Map campaign, while the World Bank said it was phasing out Mercator for Equal Earth.

Peptides can be stable in concentrated sulphuric acid: study

Researchers found that certain peptides can remain stable for weeks in 98% concentrated sulphuric acid and fold into omega-loop structures. The result challenges assumptions about acid’s incompatibility with complex biological chemistry and is relevant to assessing possible chemistry in Venus’s sulphuric-acid clouds.

Prelims pointers

  • Certain peptides remained stable in 98% concentrated sulphuric acid for several weeks at room temperature.
  • The findings were published in the Proceedings of the National Academy of Sciences on September 4.
  • In 98% sulphuric acid, the scarcity of water prevents the usual hydrolysis reaction from shredding peptide bonds.
  • Nuclear magnetic resonance spectroscopy showed the peptides folding into an omega loop supported by sulphuric-acid molecules.
  • Venus has clouds of concentrated sulphuric acid, giving the peptide result relevance to the search for extraterrestrial life.

Why is New York City pausing some AI tools in schools? | Explained

New York City imposed a one-year moratorium on student-facing generative AI through eighth grade for 2026-27, while permitting specified assistive tools, teacher uses and five high-school pilots. The report contrasts this with India’s integration approach under NEP 2020 and CBSE’s Computational Thinking and Artificial Intelligence curriculum.

No provision in Forest Rights Act to obtain gram sabha consent for projects, Tribal Affairs Ministry says

The Tribal Affairs Ministry said the Forest Rights Act, 2006 contains no provision requiring gram sabha consent for Stage-II forest clearance. Forest-diversion guidelines nevertheless require completion of FRA processes and a gram sabha no-objection certificate. A parliamentary panel proposed examining 70–75% affected-gram-sabha consent for major hydropower projects.
