It is in Portuguese, sorry for some readers, explaining some new contributions from the group of Eugene Polzik, at Niels Bohr Institute. They show how to optically measure magnetic fields with high sensitiveness and no need of cryogeny, and how this can be a viable alternative to electrocardiography (ECG), capable of noninvasive (in medical sense) monitoring of the heart of a fetus (this is the part that appeals to Luciana!).
Congratulations, Gabriel! Long life to the partnership with Luciana and with Jornal da USP.
