The art of restoration
Article Abstract:
A 'rheo-reversible' gel is helpful in removing non-original layers of the painting such as dirt. This solvent containing gels can be converted back to a free-flowing fluid state in situ for easier and more complete removal of the cleaning mixture. Methods like gas chromatography are much useful for evaluating the amount of paint media removed.

Frame dragging confirmed
Article Abstract:
Frame dragging is one aspect of the class of relativistic phenomena loosely known as gravitomagnetism, through their analogy with the effects of ordinary magnetic forces on moving electric charges. Further analysis is anticipated as additional geodesy missions are undertaken to improve our knowledge of Earth's gravity field.
