Magnetic and calorimetric measurements at extremely low temperatures and magnetic fields find superconductivity in YbRh2Si2.

Meanwhile, a second and smaller dark-matter experiment, the Calorimetric Electron Telescope, arrived at the space station last month.

Calorimetric measurements have shown that the efficiency of the human machine is about one-fifth, i.e. it can transform 20 per cent. of the energy absorbed.
