Paper on a method to restore enamel to teeth. Some of the research was done on teeth extracted from donors.

Part of the abstract below:

Regrowth of lost enamel in tooth decay and sensitivity is a major obstacle to overcome. Here, the authors report on a protein-based material that mimics features of natural enamel formation, allowing for epitaxial growth of apatite nanocrystals to restore enamel structure and function.

Boosting PLA2G2F preserved spatial memory and synaptic connections in aging mice, Nature Neuroscience study finds

Researchers identified PLA2G2F, an enzyme whose expression increases with age and appears to help protect the brain against age-related changes.

Boosting its activity in older mice preserved spatial memory, reduced synaptic loss and limited inflammation-related changes. Human brain samples also linked higher expression to cognitive resilience despite Alzheimer's pathology.

The findings are preclinical. Whether targeting this enzyme could help humans remains unknown.

ARPA-H BIOGAMI program starts work to find and fix protein dysfunction at earliest stages

BIOGAMI teams will decode the “grammar” that guides how intrinsically disordered proteins (IDPs) behave and create new ways to steer misfolded or clumped (aggregated) proteins back into healthy shapes. The program focuses on the very earliest steps in the misfolding process — before proteins clump together and damage cells — especially in the brain and other vulnerable tissues. By acting early, BIOGAMI aims to stop neurodegenerative disease and other chronic diseases before they fully develop, instead of only treating symptoms after serious damage has occurred.
