People judged AI-generated food images similarly to real food for healthiness and calorie content, but found them less realistic and were less willing to eat them. The results suggest AI images may be useful for controlled food-perception studies, but they are not interchangeable with images of real food.
This systematic review examined whether saliva samples could be used to monitor antiviral drug levels during prophylaxis or treatment in immunosuppressed people. The review included nine primary studies that reported antiviral concentrations in both saliva and plasma, but findings were limited and inconsistent. It concludes that feasibility is currently inconclusive, though preliminary evidence looks promising for some antivirals.
