KAUST unveils electricity-free cooling system 'Nescod' using ammonium nitrate

Researchers at King Abdullah University of Science and Technology (KAUST) announced Nescod, an electricity-free cooling system. Nescod stands for No Electricity and Sustainable Cooling on Demand. It uses ammonium nitrate and water in an endothermic dissolution process and requires no compressors or continuous electrical power. Solar energy is used to evaporate water and regenerate the salt for repeated cooling cycles. In tests, temperatures fell from about 25°C to 3.6°C in 20 minutes, and the system was about four times more efficient than ammonium chloride in the same setup. Ammonium nitrate is inexpensive and easy to store, aiding deployment in hot, dry environments.

Nescod uses endothermic dissolution of ammonium nitrate with water.
No compressors or continuous power are required.
Solar energy regenerates the cooling salt for cycles.
Temperature drop reached ~22°C in 20 minutes (25°C to 3.6°C).
System offers higher efficiency than some alternative salts.

IMD yellow weather alert for Chandigarh, Punjab, and Haryana (May 11–14)

The India Meteorological Department issued a yellow weather alert for Chandigarh, Punjab, and Haryana from May 11 to May 14, warning of thunderstorm, lightning, and gusty winds up to 40–50 kmph, with rain at isolated places. The forecast indicates a spike in maximum temperatures over the coming days, followed by a gradual easing of activity later in the week. Authorities advised caution for outdoor activities and to monitor local weather updates. The alert aligns with pre-monsoon weather patterns in northern India and could affect travel and outdoor events.

Alert window: May 11–14, 2026
Regions: Chandigarh, Punjab, Haryana
Predicted weather: Thunderstorm, lightning, gusty winds

CRRI-BPCL project earns India and Asia Book of Records

A joint CSIR-Central Road Research Institute (CRRI) and Bharat Petroleum Corporation Limited (BPCL) project earned recognition from India Book of Records and Asia Book of Records. The team developed roadblocks using technical textile geocells manufactured from end-of-life plastic waste, turning a difficult waste stream into durable construction material. The geocells reinforce road subgrades and improve load-bearing capacity. The ceremony at the CSIR-CRRI campus in New Delhi included senior scientists and industry experts, who highlighted the solution’s potential to address two major challenges: plastic waste management and resilient road infrastructure. The project aligns with national sustainability goals and circular economy ambitions.

Project uses geocells from end-of-life plastics.
Recognized by India Book of Records and Asia Book of Records.
Geocells improve subgrade strength and durability.
Aims to tackle plastic waste and resilient roads.
Ceremony held at CSIR-CRRI, New Delhi.

Netherlands partners with Indian spice industry on sustainability

The Netherlands has partnered with India's spice sector to advance sustainability across the spice supply chain. India remains a major global producer and exporter of spices such as pepper, cardamom, turmeric and chilli, while Rotterdam serves as a key European trade hub for these products. The collaboration focuses on soil health, water use, traceability, residue control and fair sourcing, alongside compliance with food safety and phytosanitary standards. The partnership aims to strengthen sustainable farming practices, certification processes and value chains that connect Indian growers with European markets, supporting long-term growth for both sides while promoting responsible trade practices.

Partnership focuses on sustainable spice supply chains.
India is a major global producer and exporter of spices.
Rotterdam Port acts as a European trade hub for spices.
Key focus areas: soil health, water use, traceability, residue control.

Rare Giant Tree Discovered in the Andes

Scientists have identified a rare giant tree species in the Andes, the vast mountain system that runs along the western edge of South America through seven nations: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina. The discovery adds to the Andes’ biodiversity, which spans cloud forests, páramo grasslands and montane forests that host many endemic plants and animals. Botanists used leaf shape, bark texture, flower structure, fruits and seeds, and genetic analysis to classify the tree. The find highlights the Andes as a global biodiversity hotspot and reinforces the need to protect high‑elevation habitats from threats such as climate change and deforestation. In India, on 5 May 2026, the Union Cabinet approved increasing the sanctioned strength of Supreme Court judges from 33 to 37 (38 including the Chief Justice).

Location: Andes spans seven countries
New giant tree species identified
Methods: morphology and DNA analysis
Andes biodiversity hotspot with high-elevation habitats
India policy note: Supreme Court judge strength increased on 5 May 2026
