The U.S. Food and Drug Administration (FDA) has granted full approval to Novavax’s COVID-19 vaccine, but only for certain people.

Researchers in the UC Davis Health Department of Radiology have developed a new way to use EXPLORER, the total-body positron emission tomography (PET) scanner, to speed PET parametric imaging that can detect cancer.

Immunologists from the Institute have been the first to uncover a role for a family of RNA binding proteins in the function of regulatory T cells in the immune system. As their name suggests, regulatory T cells (Tregs) play a key role in modulating the immune system response, regulating the strength of the response by limiting the function of immune effector cells, such as “killer” T cells.

Researchers led by Hiroshi Ohno at the RIKEN Center for Integrative Medical Sciences (IMS) in Japan have discovered a new way to reduce obesity. Their study shows that supplying the gut with extra acetate reduces fat and liver mass in both normal and obese mice, as long as bacteria of the Bacteroides species are also present in the gut.

PAX3 is a transcription factor (proteins involved in converting DNA into RNA) that drives melanoma progression by promoting cell growth, migration and survival, while inhibiting cellular terminal differentiation, which is the final stage where a cell becomes specialized and cell division ends. However, known PAX3 target genes are limited and cannot fully explain the wide impact of PAX3 function, suggesting that there are most likely many other genes that PAX3 controls that are undiscovered.

A new study links sleep irregularity with early precursors of heart disease in young adults with chronic anxiety. The study findings are published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology. The study has been chosen as an APSselect for May.

Smart policies addressing road transport emissions could save 1.9 million lives and prevent 1.4 million new children’s asthma cases worldwide by 2040, according to a new study.

Heritage art practices include indigenous and traditional arts practices—such as fiber arts, clay work, distinct painting styles etc.—handed down in families or communities across generations. The fact that they have been sustained for generations, and helped to serve the expressive and psychosocial needs of communities, suggests that they could be ideal approaches to supporting mental health and emotional well-being.

Since the COVID-19 pandemic, there has been a decline in U.S. vaccine uptake, while widespread misinformation and distrust make it challenging to craft effective public health responses.

Postpartum depression (PPD) affects up to 15% of individuals after childbirth. Early identification of patients at risk of PPD could improve proactive mental health support. Mass General Brigham researchers developed a machine learning model that can evaluate patients’ PPD risk using readily accessible clinical and demographic factors. Findings demonstrating the model’s promising predictive capabilities are published in the American Journal of Psychiatry.
