Good morrow and a cheerful week's end to you. This week, we reported on notable developments in the lack of starfish body development. Physicists used a new method to revisit the planetary collision that likely formed the ...
What spreads the sea floors and moves the continents? What melts iron in the outer core and enables the Earth's magnetic field? Heat. Geologists have used temperature measurements from more than 20,000 boreholes around the ...
