Much has been written of the pitfalls of being a helicopter parent, one who insulates children from adversity rather than encouraging their independence.

A growing body of scientific research is focused on One Health, the integration of knowledge concerning humans, animals and the environment. Yet there is no clear, unified definition of what a One Health study is or how such a study should be conducted.

Even in healthy individuals, the skin plays host to a menagerie of bacteria, fungi and viruses. Growing scientific evidence suggests that this lively community, collectively known as the skin microbiome, serves an important role in healing, allergies, inflammatory responses and protection from infection.

An ancient sink hole in eastern Tennessee holds the clues to an important transitional time in the evolutionary history of snakes. Among the fossilized creatures found there, according to a new paper co-authored by a University of Pennsylvania paleontologist, is a new species of snake that lived 5 million years ago.

Named for Friedrich Best, who characterized the disease in 1905, Best disease, also known as vitelliform macular dystrophy, affects children and young adults and can cause severe declines in central vision as patients age.

For a trove of examples of the rich outcomes of interdisciplinary work, look no further than Darko Stefanovski’s research portfolio.

Each year, about 2 million people contract leishmaniasis, a parasitic disease transmitted by the bite of a sand fly. The cutaneous form of the disease results in disfiguring skin ulcers that may take months or years to heal and in rare cases can become metastatic, causing major tissue damage.
