Pubblichiamo il podcast In un cerchio di padri realizzato per il progetto 4E-Parent in cui si può ascoltare l'intervista ad Andrea Santoro sulla sua esperienza del "cerchio dei padri".
4E-Parent è un progetto europeo che intende promuovere l’impegno dei padri da subito nella cura di figlie e figli, e ha tra gli obiettivi principali l'introduzione in Italia di un congedo di paternità analogo quello di maternità.
A group of researchers from Hokkaido University has provided the first experimental evidence of the existence of a new type of chemical bond: the single-electron covalent bond, theorized by Linus Pauling in 1931 but never verified until now. Using derivatives of hexaarylethane (HPE), the scientists were able to stabilize this unusual bond between two carbon atoms and study it with spectroscopic techniques and X-ray diffraction. This discovery opens new perspectives in understanding bond chemistry and could lead to the development of new materials with innovative applications.

After nearly a year of review, on September 25, a study was published in Nature that has sparked a lot of discussion, especially among chemists. A group of researchers from Hokkaido University synthesized a molecule that experimentally demonstrated the existence of a new type of chemical bond, something that does not happen very often.
