    Pain related to sickle cell disease (SCD) increases during menstruation, as do emergency department (ED) visits and hospitalizations, for many women and girls—according to a new, nationwide study led by researchers at UC San Francisco. The study, published in JAMA Network Open, included 211 female patients from 13 SCD centers across 11 states.

  • Will probiotics work for you? Models map gut metabolism to predict success
    on February 19, 2026 at 8:36 pm

    A new study demonstrates that computer models of gut metabolism can predict which probiotics will successfully establish themselves in a person’s gut and how different prebiotics affect production of health-promoting short-chain fatty acids. The findings are published in PLOS Biology by Sean Gibbons of the Institute for Systems Biology, US, and colleagues.

  • Colorism might help explain health inequities suffered by dark-skinned Black Americans, researchers say
    on February 19, 2026 at 8:34 pm

    A study of Black Americans is among the first to show how the internalization of negative messages about dark skin tones could be linked to harms to health. Researchers found that Black Americans who are, or perceive themselves to be, dark-skinned show clear markers of cellular aging associated with immune-system damage and also score lower on a measurement of self-worth. Cellular aging and low self-worth are both associated with relatively poor health outcomes.

  • Oral vaccine strategy used modified bacterium to combat colorectal cancer
    on February 19, 2026 at 8:33 pm

    A research team investigating the use of the bacterium Listeria monocytogenes against colorectal cancer has discovered a way to build a modified version of Listeria as an oral vaccine to prime the immune system directly within the gut, where anti-tumor cells are then generated. Details of the work, led by Stony Brook immunologist Brian Sheridan, Ph.D., are published in the Journal for the ImmunoTherapy of Cancer.

  • Fiber-free processed foods hit emotional memory fast, especially in older brains
    on February 19, 2026 at 8:20 pm

    Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain—and the effect can happen fast, after just three days of poor eating.
