  • Miniaturized bone marrow-on-a-chip tracks human immune cells as they build lasting antibody defenses
    on September 14, 2026 at 5:00 pm

    A scientific team has developed a laboratory model that reveals how antibody-producing plasma cells migrate, mature and survive within human bone marrow, a main location of long-lived antibody-producing plasma cells. The platform combines a lymph node-mimicking organoid with a tissue chip that mimics bone marrow, allowing scientists to observe key stages of plasma cell development that have been difficult to study in humans.

  • Examining the neural basis of socially anxious behaviors
    on September 14, 2026 at 5:00 pm

    People with social anxiety are especially sensitive to unpleasant outcomes, and this sensitivity contributes to their tendency to avoid social situations. Previous research has linked this learning bias to activity in specific brain regions. Hanjie Liu and Melle van der Molen of Leiden University extended this work by examining how communication between brain regions coordinates learning behavior in people with varying levels of social anxiety.

  • Gut infection may train immune sentries at the brain’s border to remember microbes
    on September 14, 2026 at 4:40 pm

    The brain and spinal cord are highly protected treasures of the central nervous system, wrapped under three protective layers of meninges. The outermost layer, the dura mater, has leaky windows through which bacteria or parasites circulating in the blood can reach the central nervous system. As a line of defense against these sneaky attacks, the dura layer houses multiple populations of immune cells. Does that mean events like infections and inflammation that challenge the immune system in the gut can train and alter immune cells in the brain’s outer protective layer?

  • Young military veterans have higher ‘forever chemical’ levels than non-veterans
    on September 14, 2026 at 4:40 pm

    Per- and polyfluoroalkyl substances (PFAS), often called forever chemicals because of their long-lasting presence in humans and the environment, are commonly found in consumer and industrial products. When Brown University researchers examined PFAS levels in the blood serum of U.S. military veterans, they found that younger veterans had higher PFAS concentrations and a higher prevalence of elevated PFAS levels compared with civilians of similar ages.

  • Early deafness may reshape the brain to devote more resources to peripheral vision
    on September 14, 2026 at 4:20 pm

    People with intact hearing can use sound as an alert system for events outside their direct line of sight. This seemingly puts those who have lost their hearing at a disadvantage. However, according to a new study published in Proceedings of the National Academy of Sciences, the brains of people who lose their hearing at an early age may compensate by devoting more resources to developing better peripheral vision.
