'Molecular compass' points way to reduction of animal testing      (via sciencedaily.com)     Original source 

Machine learning models have become increasingly popular for risk assessment of chemical compounds. However, they are often considered 'black boxes' due to their lack of transparency. To increase confidence in these models, researchers proposed carefully identifying the areas of chemical space where these models are weak. They developed an innovative software tool for this purpose, and the results of this research approach have just been published.

Wearable, stretchable sensor for quick, continuous, and non-invasive detection of solid-state skin biomarkers      (via sciencedaily.com)     Original source 

Detecting diseases early requires the rapid, continuous and convenient monitoring of vital biomarkers. Researchers have now developed a novel sensor that enables the continuous, and real-time detection of solid-state epidermal biomarkers, a new category of health indicators. The team's wearable, stretchable, hydrogel-based sensor overcomes the limitations of current methods that rely on biofluid samples, such as blood, urine and sweat. This makes it a promising alternative for wearable, continuous, and real-time health monitoring, facilitating the early detection of conditions such as cardiovascular diseases and stroke.
