Scientists have developed a "digital mask" that will permit the storage of facial photographs in medical records while limiting the extraction and sharing of potentially sensitive personal biometric data. Researchers from the University of Cambridge and Sun Yat-sen University in Guangzhou, China, used three-dimensional (3D) reconstruction and deep learning algorithms to remove recognizable features from facial images while keeping disease-relevant features required for diagnosis in research published today in Nature Medicine. Images of the face can be helpful in spotting illness symptoms. Deep forehead wrinkles and wrinkles around the eyes, for instance, are strongly linked to coronary heart disease, whereas aberrant alterations in eye movement may be an indication of poor visual function or developmental issues with the visual-cognitive system. Facial photos invariably capture additional biometric data about the patient, such as their race, sex, age, and mood. Data leaks are...

The "sweet spot" for reducing your risk of disease and mortality is 10,000 steps per day, but recent research suggests that your walking speed may be just as significant. The studies, which tracked 78,500 participants with wearable trackers and were published in the journals JAMA Internal Medicine and JAMA Neurology, are the largest to systematically examine step count in connection to health outcomes. Achieving 10,000 steps per day is linked to a lower risk of dementia, heart disease, cancer, and death, according to studies from the Universities of Sydney in Australia and Southern Denmark. A power walk, however, demonstrated advantages above and beyond the amount of steps completed. "The take-home message here is that people could not only ideally aim for 10,000 steps a day for protective health benefits but also aim to walk faster," said Dr. Matthew Ahmadi, co-lead author and Research Fellow at the Charles Perkins Centre and Faculty of Medicine and Health at the U...
