 A
new study has revealed how brain circuits and neurotransmitters regulate meal initiation, offering insights into obesity management. Researchers identified serotonin neurons in the midbrain's dorsal Raphe nucleus (DRN) as key players, inhibited by GABA and
dopamine when hunger strikes.

 Researchers
used AI to analyze brain images from 70-year-olds, estimating their biological brain age and uncovering connections to lifestyle and health factors. Diabetes, inflammation, and high glucose levels were linked to older-looking brains, while regular exercise
and healthy habits were associated with younger-looking brains.

 Researchers
have linked chronic intestinal infections caused by cytomegalovirus (HCMV) to a unique subtype of Alzheimer’s disease. The virus may travel from the gut to the brain via the vagus nerve, altering immune responses and contributing to hallmark Alzheimer’s changes
like amyloid plaques and tau tangles. While HCMV infection is common and typically harmless, this study found that it may cause chronic brain inflammation in certain individuals.

 Women
born in states with higher structural sexism experience faster memory decline later in life, with effects equivalent to nine years of cognitive aging. Structural sexism encompasses societal inequities like unequal labor force participation and underrepresentation
in government, which create systemic barriers to health. The impact is particularly pronounced among Black women, highlighting the intersection of sexism and racism.
