    Smart probiotics can sense high blood sugar and release GLP-1 on demand

GIFT cells are orally administered to diabetic mice and monkeys, temporarily colonize the intestine and secrete GLP-1 in response to high glucose levels, leading to an abolishment of persistent hyperglycemia.

    For people living with diabetes, managing blood sugar can mean constantly watching the clock, keeping meals and medications on schedule and staying alert to changes in glucose levels. While little can be done about timed meals, researchers have developed a biological system that detects rising blood sugar levels and automatically responds by releasing medication to bring glucose back down.

    In a recent study published in...

    Science seems like a straightforward endeavor. You come up with a hypothesis, collect data to prove or disprove it, and analyze that data to see whether the hypothesis is right. But anyone who actually does science will tell you that it is often not that straightforward. One of the most common complexities is data analysis.

    A new paper in Nature suggests that one such complexity, known as regression to the mean, might be causing us to massively underestimate how severe solar storms can be.

    The interaction between the solar wind and Earth’s magnetosphere can be thought ...

    Blood proteins may flag disability risk years before loss of independence

    Towards early disability prediction with blood protein biomarkers
    Researchers identified two blood proteins—beta-2-microglobulin (B2M) and cystatin C—that predict future disability in community-dwelling adults aged 85 years and older. The findings, validated in independent Japanese and Italian aging cohorts, suggest that blood-based biomarkers could support earlier identification of older adults at risk of losing independence and guide timely preventive interventions.

    Japan has one of the world’s fastest-aging populations, but maintaining independence into very old age remains a growing public health challenge...

    Robots learn new skills from a single video—in just 29 seconds

    Framework could teach robots new skills from a single video
    Robots acquire manipulation skills in seconds from a single human video. (A) Current methods teach a robot new skills through a cumbersome training-time loop that is costly and slow, and erodes previously mastered skills. HOST instead acquires skills at inference time, each from a single human video, averaging 29 seconds, while retaining its previously mastered skills. (B) Skill acquisition from a single human video confronts a structural mismatch between video demonstration and execution. Temporal asynchrony between the two decouples the prediction target from the video demonstration, while state discrepancies hinder the translation of the observed behavior into action...
