Mystery of 60-second fluctuations in power grids solved

TenneT Germany, the largest transmission system operator in Germany, has observed over several years that the frequency in the European power grid dips briefly every 60 seconds. While these deviations were not critical to ...

Engineering

New virtual assistant streamlines one of the most advanced microscopes

Some of the most important discoveries in materials science and structural biology come down to a simple question: Where, exactly, are the atoms? The arrangement of atoms determines nearly everything about how a material ...
