Un recente studio pubblicato su Thorax trova una decisa correlazione fra esposizione professionale ai pesticidi e il rischio di ammalarsi di broncopneumopatia cronico ostruttiva (BPCO), fra le prime cause di morte nel mondo. La ricerca, condotta sul data base UK biobank da un consorzio internazionale coordinato dall'Imperial College di Londra, vede come prima firma Sara de Matteis, medico ed epidemiologa del lavoro, ora professore associato presso l'Università di Cagliari. L'abbiamo intervistata per fare il punto sulla ricerca e sul problematico rapporto fra pesticidi e salute.

Why have neural networks won the Nobel Prizes in Physics and Chemistry?
This year, Artificial Intelligence played a leading role in the Nobel Prizes for Physics and Chemistry. More specifically, it would be better to say machine learning and neural networks, thanks to whose development we now have systems ranging from image recognition to generative AI like Chat-GPT. In this article, Chiara Sabelli tells the story of the research that led physicist and biologist John J. Hopfield and computer scientist and neuroscientist Geoffrey Hinton to lay the foundations of current machine learning.

The 2024 Nobel Prize in Physics was awarded to John J. Hopfield, an American physicist and biologist from Princeton University, and to Geoffrey Hinton, a British computer scientist and neuroscientist from the University of Toronto, for utilizing tools from statistical physics in the development of methods underlying today's powerful machine learning technologies.
