Researchers at Brown University found that AI chatbots routinely violate core mental health ethics standards, underscoring the need for legal standards and oversight as use of these tools increases.
To understand what drives changes in physical activity after cardiovascular diagnosis, scientists performed machine learning analyses on data from 295 adults over 60 years included in the UK Biobank who had been diagnosed with diseases of the heart and blood vessels. These data included brain scans and answers to health surveys and social background questionnaires.
The researchers found that people who increased their physical activity levels long-term after diagnosis tended to have greater access to greenspace and social support than those who got less exercise, factors that make it easier to sustain healthy habits. At a neurological level, the researchers found people with increased brain connectivity between the right superior frontal gyrus and both the ventromedial prefrontal cortex and the precuneus showed greater physical activity.
Researchers at the HUN-REN Biological Research Centre, Szeged, Hungary, have developed an artificial-intelligence-assisted technology capable of analyzing up to one hundred patient-derived cell samples simultaneously.
The new method, described in Nature Communications, could significantly accelerate drug development and advance the field of personalized medicine.

Traditional geotechnical investigations provide data only at discrete borehole locations, leaving vast areas uncharacterized. This spatial gap often leads to unforeseen ground conditions during construction, causing costly delays, design modifications, and occasionally catastrophic failures. Now, a novel integrated geophysical-machine learning approach, using k-means clustering technique, by a team of researchers from Shibaura Institute of Technology provides continuous subsurface characterization, enabling evidence-based decision-making throughout project lifecycles.
