The XII CAML PhD Students’ Meeting was held from 23rd-25th May at Ed. Egas Moniz, FMUL/iMM-JLA and counted with the participation of 92 PhD Students and fantastic talks from invited speakers. Dr. Suzana Herculano-Houzel showed the relationship between the number of neurons and longevity of the species. Dr. Thomas Pradeu persuaded us to think about the philosophical concepts behind what we study, to efficiently design experiments and conclude about our results. Dr. María Blasco showed how increased telomeres - the end structure of the chromossomes - might protect against cancer and metabolic diseases, while Dr. António Almeida highlighted the importance of the crosstalk between basic and translational research, under the light of epigenetics. Finally, Dr. Paulo Vieira gave us useful tips on how to better manage our time. We would like to thank the entire scientific community that participated in the meeting and contributed its success.
