DANA Causes Flash Floods in Spain
Syllabus: GS1/ Physical Geography
In News
- Catastrophic flash floods in Spain caused havoc mainly attributed to the DANA Phenomenon.
About DANA
- Known in Spain as DANA (Depresión Aislada en Niveles Altos) or high-altitude isolated depression, this system can develop independently of typical jet streams, unlike regular storms.
- Formation Mechanism: Cold air moves over warm Mediterranean waters, causing warm air to rise quickly.
- This forms dense, moisture-filled clouds that can stay in one area, increasing the likelihood of severe flooding.
- DANA mostly occurs in autumn, when summer’s warm surface heat meets sudden cold air from polar regions, creating a low-pressure system that remains over a specific region.

Aditya-L1 Mission
Syllabus: GS3/ S&T
In News
- The first scientific result from Aditya-L1 has been released.
About
- Using data from the Visible Emission Line Coronagraph (VELC), scientists were able to observe the precise onset of a coronal mass ejection (CME) from the Sun.
- The Coronal Mass Ejection (CME) can damage the electronics in satellites in near-earth space and disrupt radio communication networks on the earth. Understanding and predicting CMEs is crucial for protecting technology and infrastructure.
About Aditya L1 mission
- The Aditya-L1 mission is India’s first dedicated scientific mission to study the Sun. The mission aims to observe and analyze various aspects of the Sun from Lagrangian Point 1 (L1).
- Lagrangian Point 1 (L1) is a position in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, are in equilibrium. At this point, Aditya-L1 can continuously observe the Sun without any interference.

Connection Between Nickel Toxicity and Sterols
Syllabus: GS3/Science and Technology
Context
- Researchers have discovered that exposing mammalian and fungal cells to the heavy metal nickel resulted in sterol deficiency.
- Until this report, no one suspected nickel toxicity was related to sterol biosynthesis in fungi and animals.
About
- In fungi, including yeast, the major sterol is ergosterol. Blocking ergosterol biosynthesis can adversely affect fungal growth.
- Most important agents humans use to fight fungal infections are azoles (like fluconazole) inhibit ergosterol biosynthesis.
Sterols
- In Plants: Sterols are an important chemical component of the cell membranes of plants, animals, and fungi. The compound makes the membranes more rigid.
- In mammals including humans, the principal sterol is cholesterol.
- If it is present in high concentrations in the body, it tends to be deposited in the inner lining of our blood vessels.
- As the deposits accumulate, they block the flow of blood, eventually leading to chest pain, heart attack, and/or stroke.
- Doctors widely used drugs called statins to reduce the amount of cholesterol the body makes — i.e. cholesterol biosynthesis — to avoid these adverse outcomes.
- The study could help in discovering a novel antifungal agent.

Toy Train on Green Hydrogen
Syllabus: GS3/Environment
Context
- Himachal Pradesh Chief Minister, urged the Central government to explore the possibility of running trains on the Kalka-Shimla narrow-guage railway, a UNESCO world heritage site, on green hydrogen.
About
- The transition would help the state in achieving its goal of becoming a ‘green energy state’ by 2026.
- The State is on track to replace its current thermal power consumption of 1,500 Million Units (MUs) with renewable sources, including hydro, solar, and wind power.
What is Green Hydrogen?
- Green hydrogen refers to hydrogen that is produced using renewable energy sources, such as wind, solar, or hydropower, through a process called electrolysis.
- Electrolysis involves splitting water (H2O) into hydrogen (H2) and oxygen (O2) using an electric current.
- When this electricity comes from renewable sources, the hydrogen produced is considered “green” because the overall process has a minimal environmental impact.
- Benefit: It is a clean burning element that can decarbonise a range of sectors including iron and steel, chemicals, and transportation.
- Hydrogen can be stored for long periods of time which can be used to produce electricity using fuel cells.
