Human sound systems are shaped by post-Neolithic changes in bite configuration

Science

Biomechanical models of the speech apparatus show that labiodentals incur about 30% less muscular effort in the overbite and overjet configuration than in the edge-to-edge bite configuration. This difference is not present in similar articulations that place the upper lip, instead of the teeth, against the lower lip (as in bilabial "m," "w," or "p"). Our models also show that the overbite and overjet configuration reduces the incidental tooth/lip distance in bilabial articulations to 24 to 70% of their original values, inviting accidental production of labiodentals. The joint effect of a decrease in muscular effort and an increase in accidental production predicts a higher probability of labiodentals in the language of populations where overbite and overjet persist into adulthood. When the persistence of overbite and overjet in a population is approximated by the prevalence of agriculturally produced food, we find that societies described as hunter-gatherers indeed have, on average, only about one-fourth the number of labiodentals exhibited by food-producing societies, after controlling for spatial and phylogenetic correlation.

The 2018 NJPHA Annual Conference was a huge success - thank you to all who participated. If you weren't able to join us, please click on the talk titles to view individual video recordings. We look forward to seeing you in 2019. This Conference is a collaboration between the New Jersey Public Health Association and the Rutgers University School of Public Health. The conference will bring local, state, and national public health leaders together to initiate a pragmatic dialogue addressing broad determinants of health and integrated solutions, and exhibiting the need for partnership and collective efforts towards provision of a fair and just opportunity for all New Jersians to be healthier.


Lloyd Dean of Dignity Health: Housing a Driver, Race a Divider in Health Care

U.S. News

I think it's a moral imperative that we act. We live in one of the wealthiest nations on the planet. It's the humane thing to do. But then when you look at it from a health care perspective, the science is on our side. A lot of times the people that are out there – not always, but a high percentage in places like Chicago, in major cities but even in some of the suburban areas – folks present with multiple diagnoses.


Rutgers, RWJBarnabas Health Launching Academic Health System

U.S. News

RWJBarnabas, which owns 11 acute-care hospitals and several other facilities in the state, will initially contribute $100 million and then more than $1 billion over 20 years to expand education and research. It also will pay for construction of a clinical and research building for the Rutgers Cancer Institute of New Jersey and an ambulatory care center, both in New Brunswick.


What doctor? Why AI and robotics will define New Health

#artificialintelligence

Modern health systems can treat and cure more diseases than ever before. New technology is bringing innovation to old treatments. Yet significant quality, access and cost issues remain and our health systems are becoming increasingly unsustainable. The emergence and increasing use of artificial intelligence (AI) and robotics will have a significant impact on healthcare systems around the world. How will AI and robotics define New Health?
