Decoding the purpose of fetal yawns in the womb

Even in the womb, where all oxygen is provided by the parental placenta, fetuses can-and do-yawn. More yawns during observation were associated with a lower weight at birth-potentially indicating mild fetal stress in the womb, according to a study published February 25, 2026 in the open-access journal PLOS One by Damiano Menin, of the Università degli Studi di Ferrara in Italy, and colleagues.

Long-term cola intake weakens immune cell counts in controlled rat study

Replacing drinking water entirely with sugar-sweetened or sugar-free cola for eight weeks altered gut microbiota composition and immune-related indices in rats, despite no changes in body weight or blood glucose. Both beverages were associated with leukocyte reductions and organ-related biochemical shifts, with sugar-sweetened cola more strongly linked to renal markers and diet cola to elevated liver enzymes.

Having “hasslers” in your network linked to faster aging and poorer health

Researchers analyzed a state-representative US sample to examine whether negative social ties, termed “hasslers,” are associated with epigenetic age acceleration and faster biological aging. Each additional hassler was linked to roughly nine months higher biological age and a 1.5% faster pace of aging, with particularly strong associations for mental health outcomes.
