MIT researchers developed an interactive, AI-based system that enables users to rapidly annotate areas of interest in new biomedical imaging datasets, without training a machine-learning model in advance. As the user uploads new images, the number of interactions needed to accurately segment the image drops, eventually to zero, enabling rapid annotation of the entire dataset.

Stroke patients evaluated using telemedicine (telestroke) have higher odds of receiving essential treatment, yet it takes them significantly longer to be treated — potentially limiting the benefits, a study finds. Telestroke patients had 44% lower odds of being successfully treated within 60 minutes of getting to the hospital.

About The Study: This cross-sectional study suggests that despite increasing clearance of artificial intelligence (AI)/machine learning (ML) devices, standardized efficacy, safety, and risk assessment by the Food and Drug Administration (FDA) are lacking. Dedicated regulatory pathways and post-market surveillance of AI/ML safety events may address these challenges.

About The Study: This study found that nearly one-quarter of pediatric firearm-related homicides occurred at home. Young children were more often affected. These data point to domestic violence and child abuse as significant risk factors for in-home firearm homicide. Traditional safe storage laws may be inadequate preventive measures. Extreme risk protection orders and mandatory domestic violence–related firearm relinquishment may prevent these deaths and warrant further investigation. 

It is a fully biodegradable and eco-friendly system for hydroponic agriculture, made of hydrogel and capable of supporting plant growth with minimal water; in the future, it will be able to monitor plant health in real time. This innovation is the result of joint research between the Faculty of Engineering at the Free University of Bozen-Bolzano (UniBz) and the Istituto Italiano di Tecnologia (IIT-Italian Insititute of Technology) in Genoa. The invention offers a zero-waste, low-environmental-impact solution for agriculture, a sector increasingly threatened by climate change, drought, pollution, biodiversity loss, and soil degradation.
