A major challenge in self-powered wearable sensors for health care monitoring is distinguishing different signals when they occur at the same time. Researchers addressed this issue by uncovering a new property of a sensor material, enabling the team to develop a new type of flexible sensor that can accurately measure both temperature and physical strain simultaneously but separately to more precisely pinpoint various signals.

Newborns with heart complications can rely on their newly developed immune systems to regenerate cardiac tissues, but adults aren't so lucky. After a heart attack, most adults struggle to regenerate healthy heart tissue, leading to scar-tissue buildup and, often, heart failure. A new study in experimental animals reveals a critical difference in how macrophages -- a part of the immune system -- help repair the heart in newborns versus adults after a heart attack. The study highlights a fundamental difference in how the immune system drives healing based on age.

A new study has discovered in mouse models that genes associated with repairing mismatched DNA are critical in eliciting damages to neurons that are most vulnerable in Huntington's disease and triggering downstream pathologies and motor impairment, shedding light on disease mechanisms and potential new ways to develop therapies.
