  • SARS-CoV-2 delta and omicron BA.2 show clustered spike D614 reversions. What it could mean for surveillance
    on April 4, 2026 at 6:30 pm

    Researchers from University of Tsukuba and Institute of Science Tokyo have identified nonrandom patterns in the emergence of spike D614 reversions in publicly available SARS-CoV-2 genomic data. Analysis of publicly available sequences revealed numerous instances in which the spike D614G substitution, previously associated with increased transmissibility, reverted from G614 to the ancestral D614 residue, with these events predominantly occurring in the delta and omicron BA.2 lineages. The detected reversions also exhibited nonrandom patterns in temporal occurrence and geographic distribution.

  • Stress tested, testing stress: Novel organoid models how the adrenal gland develops

    Sitting above each kidney are two small endocrine glands about the size of walnuts. These are the adrenal glands, responsible for producing hormones that help control some of the body’s most critical functions. Among these hormones, cortisol is particularly critical for survival. Often referred to as the “stress hormone,” it helps the body adapt to a wide range of challenges—both emotional and physical, such as trauma or infection—by regulating overall metabolism. Despite its central role in stress and endocrine biology, how the adrenal gland is built and how it functions remains poorly understood.

  • Smart sensor decodes fatigue and stress from body signals on the move

    About one in three employees in Singapore report feeling burnt out—one of the highest rates globally. Burnout and chronic fatigue carry a substantial economic cost and pose serious risks in professions where alertness is critical. Yet diagnosing fatigue and related mental health conditions today relies largely on self-reported questionnaires, which tend to be subjective, intermittent, and poorly suited to real-time evaluation.

  • No need to sign up for gym: Even small movements have health benefits

    South Africa is facing an alarming increase in non-communicable diseases and related mortality. According to Statistics South Africa, deaths due to non-communicable diseases such as type 2 diabetes and hypertension increased by over 58% between 1997 and 2018.

  • Longer weekly home-visit rehabilitations linked to improved activities of daily living in older adults
    on April 4, 2026 at 4:00 pm

    In aging societies, the role of home-visit rehabilitation (HR)—which provides physical, occupational, and speech therapy in patients’ homes—is becoming increasingly important for supporting independent living. Although previous studies have shown that HR can help maintain and improve activities of daily living (ADL) among older adults with limited access to outpatient services, the dose-response relationship between the amount of HR time per week and ADL improvement remains unclear.
