The NHS needs to revise its vision and focus on equity, availability, accessibility, and quality based on UN principles. A Technical Advisory Group, General Health Council, and annual assessment are proposed to strengthen the NHS.
Researchers found that humans prefer novel stimuli over familiar ones and associate novelty with activation of the ventral striatum, a region linked to reward anticipation. This suggests humans use novelty as a substitute for true choice uncertainty.
Research finds that people sometimes prioritize the greater good over their own interests, and poorly designed institutions can undermine this behavior. Examples include a study on day care center fines and blood donation rates., Experts argue that recognizing human altruism is crucial for designing effective policies and institutions.

A study of 1,956 pre-schoolers found that tooth grinding during sleep was associated with worse pre-school adjustment, including social withdrawal and behavioral issues. Parents' reports of tooth grinding may be a sensitive indicator of bruxism in young children.
A study of 97 couples found that fathers are more involved in infant care when their wives provide active encouragement, regardless of their own beliefs or the quality of parenting. Encouragement from mothers can either foster or limit fatherly participation, with mothers acting as 'gatekeepers' to their involvement.
Researchers have created a genetically altered monkey model that replicates symptoms of Huntington's disease, allowing for a deeper understanding of the disease mechanisms. This breakthrough could lead to major advances in developing new treatments for neurological diseases.
