A new study brings attention to a different type of glacier - Rock glaciers, which are landforms composed of rocks and ice, and their importance.

Detecting leakage of hydrgoen gas has been a major challenge in using hydrogen as fuel for many applications. This is now made easier by a new study by researchers at the Indian Institute of Technology, Roorkee. They have used  nanotechnology based silicon carbide ‘cauliflowers’ to develop a simple, robust, and cost-effective sensor that can detect hydrogen gas at high temperatures and small quantities. This research is a small step that can make using clean and green hydrogen gas as fuel, replacing conventional fossil fuels.
