Huge helium gas reserve found in Africa
England-based researchers have found around 54 billion-cubic-feet of helium gas in Tanzania's Rift Valley, Africa. The gas, which is vital but relatively rare, is critical in areas like MRI scanners, welding, and industrial leak detection. The find is being called a "game-changer" in addressing a critical shortage, as until now the gas was usually discovered accidentally and in small quantities.
