Scientists explain why we obey rules even when no one benefits

New research reveals many people follow costly, arbitrary rules even without external pressure or benefit to others. This conformity stems largely from intrinsic respect for rules and social expectations, more so than just incentives or direct social benefits.

Rethinking the mitochondrial theory of aging

The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria are cell organelles that produce energy essential for life activities through oxidative phosphorylation (mitochondrial respiration), and mtDNA encodes a set of genes required for mitochondrial respiration.

Understanding cow’s milk allergy in breastfed infants

Cow’s milk allergy (CMA) affects up to 2.2% of infants, with a complex interplay of immunological mechanisms, allergen transfer via breast milk, and variable responses to maternal elimination diets. Current evidence challenges the routine use of maternal dietary restrictions, highlighting the need for precise diagnosis and further research.

Which diet lowers blood pressure more: keto or Mediterranean?

A pilot study comparing a low-calorie, high-protein ketogenic diet and a Mediterranean diet in overweight and obese adults with elevated blood pressure found that both diets led to significant weight loss, improved body composition, and reduced blood pressure. Both dietary approaches were safe and well-tolerated, but the Mediterranean diet group showed a greater proportion of participants with healthy nocturnal blood pressure dipping.
