Specifically, we have measured the specific heat of 110\nmillion-year-old amber samples from El Soplao (Spain), both at very low\ntemperatures and around the glass transition Tg. In particular, the amount of\ntwo-level systems, assessed at the lowest temperatures, was surprisingly found\nto be exactly the same for the pristine hyperaged amber as for the,\nsubsequently, partially and fully rejuvenated samples.', 'mimetype': 'text/plain', 'lang': 'en'}
