Research in 2023 yielded insights on drinking, sleep, guns, longevity, and whether the good old days really were.
The work of research and discovery at the University crowds the calendar month to month, rewarding and propelling the pursuit of knowledge. Here we highlight findings from 2023 that tell us more about the forces that shape our society, our relationships, and our physical and mental health.

‘Moral breakdown is a fake problem’
