Janine Kwapis, the Paul Berg Early Career Professor in the Biological Sciences at Penn State, has been appointed director of the University's Center for Molecular Investigation of Neurological Disorders (CMIND), an interdisciplinary research unit within the Huck Institutes of the Life Sciences

Less sleep and later bedtime in childhood linked to future substance use

A good night’s sleep is essential for children’s health and development, but childhood sleep patterns may also be linked to future substance use. A new study led by a team of Penn State researchers found that adolescents were more likely to have consumed alcohol or tried marijuana by age 15 if they went to bed later and slept fewer hours during childhood and adolescence.

Rewriting the evolutionary history of critical components of the nervous system

A new study has rewritten the conventionally understood evolutionary history of certain proteins critical for electrical signaling in the nervous system. The study, led by Penn State researchers, shows that the well-studied family of proteins — potassium ion channels in the Shaker family — were present in microscopic single cell organisms well before the common ancestor of all animals.

Memory problems in old age linked to a key enzyme, study in mice finds

A team of researchers from Penn State has identified an enzyme that contributes to age-related impairments in memory updating. When blocked, older mice were better able to incorporate new information and performed similarly to their younger counterparts. The researchers said the findings may lead to the development of potential therapeutic targets for improving cognitive flexibility in old age.
