GeologyAfter lightning struck a tree in a New Port Richey neighborhood, a University of South Florida professor discovered the strike led to the formation of a new phosphorus material. It was found in a rock – the first time in solid form on Earth – and could represent a member of a new mineral group.

GeologyNot long ago it was thought Earth’s structure was comprised of four distinct layers: the crust, the mantle, the outer core and the inner core. By analysing the variation of travel times of seismic waves for different earthquakes scientists believe there may be a fifth layer.

GeologyResearchers have looked at the Jack Hills zircons in previously unseen detail, revealing that any magnetic signal they have is too young, dating from roughly 2 billion years ago. In other words, the much-debated question of when Earth first got its magnetic field remains unanswered.
