Two new experimental techniques that make coulometric and calorimetric measurements of porous electrodes are used to obtain the entropic contribution to the grand potential. The new results differ significantly from theoretical predictions.

A pulsar PSR J1023+0038 switches between two states that have different spin-down rates. A new analysis suggests that this discrepancy may be due to gravitational wave emission.
