Researchers at Nemours Children's Health System have found that an artificial intelligence (AI) behavioral coach, nicknamed Tess (X2ai, Inc), is feasible and useful for behavioral counseling of adolescent patients in a weight management program. The study, published today in the journal Translational Behavioral Medicine, demonstrates adolescents' willingness and positive reaction to engaging in SMS text conversations with the chatbot technology that simulates human interactions.

Children who use asthma tracking app have better disease control and fewer hospital visits
An app that allows parents and doctors to monitor a child's asthma has a big impact on managing the disease. When families monitored symptoms with eAsthma Tracker and adjusted care accordingly, children had better asthma control and made fewer visits to the emergency department. Using the app also meant that children missed fewer days of school and parents took fewer days off work, improving quality of life. Results of the study were published online in the journal Pediatrics.

Malnourished fruit flies preserve genital size to ensure reproductive success
In most animals, body size shrinks when food becomes scarce, but some parts are protected from shrinkage. In humans without enough food, the body becomes small, but the size of the head stays the same, hinting at biological mechanisms that act to preserve the all-important brain.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Exploring people's perception of geometric features, personalities and emotions in videos with virtual humans
Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

Cancer drugs promote stem cell properties of colorectal cancer
Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Mannheim University Medical Center have now discovered that a certain group of cancer drugs (MEK Inhibitors) activates the cancer-promoting Wnt signaling pathway in colorectal cancer cells. This can lead to the accumulation of tumor cells with stem cell characteristics that are resistant to many therapies and can lead to relapses. The researchers thus provide a possible explanation for why these drugs are not effective in colorectal cancer.

Framework improves 'continual learning' for artificial intelligence
Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while "forgetting" less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.
