Delving into manganite conductivity
— 10 Feb 2011 19:19 | PhysicsChemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields…
How do you make lithium melt in the cold?
— 10 Jan 2011 18:51 | PhysicsSophisticated tools allow scientists to subject the basic elements of matter to conditions drastic enough to modify their behaviour. By doing this, they can expand our understanding…
Tiny 3-D images shed light on origin of Earth's core
— 18 Dec 2010 14:27 | Geology and palaeontologyTo answer the big questions, it often helps to look at the smallest details. That is the approach Stanford mineral physicist Wendy Mao is taking to understanding a major event in Earth's…
