Electronic Screen Use and Sleep Duration and Timing in Adults

JAMA Network Open

2025-03-27

(Press-News.org) About The Study: Daily screen use was associated with later bedtimes and approximately 50 minutes less sleep each week in this study. Associations were greater among those with evening chronotypes, who are at risk for poor sleep due to social jetlag (i.e., misalignment between circadian rhythms and social commitments). These findings confirm disruptions to sleep from electronic screens are not limited to children and adolescents. Further work is needed to understand the best mechanisms for intervention.

State Minimum Wage and Food Insecurity Among US Households With Children

2025-03-27

About The Study: In this pooled cross-sectional study, findings suggest that state legislatures that elected to increase their state minimum wage may have also improved state food security rates among households with children at risk for economic hardship. The findings provide policymakers with actionable evidence to consider in setting minimum wages that could reduce the burden of food insecurity among U.S. children and families.

Novel adsorbent offers effective solution for perchlorate removal from water

2025-03-27

A study published in Engineering introduces an innovative approach to address the issue of perchlorate (ClO4−) contamination in water. Perchlorate is a harmful oxo-anion found in aquatic environments. It can enter the human body through drinking water and inhibit iodine absorption in the thyroid gland, potentially causing various thyroid-related diseases. Given the strict perchlorate limits in drinking water worldwide, such as 70 μg/L in China and 15 μg/L in the United States, developing efficient methods for its removal is crucial. The research team, hailing from Hunan University and Shanghai Jiao Tong University, prepared an adsorbent ...

Terahertz imaging reveals new views of internal cochlear structure

2025-03-27

WASHINGTON — For the first time, researchers have shown that terahertz imaging can be used to visualize internal details of the mouse cochlea with micron-level spatial resolution. The non-invasive method could open new possibilities for diagnosing hearing loss and other ear-related conditions. “Hearing relies on the cochlea, a spiral-shaped organ in the inner ear that converts sound waves into neural signals,” said research team leader Kazunori Serita from Waseda University in Japan. “Although conventional imaging methods often struggle to visualize this organ’s fine details, ...

Machine learning program enhances transplant risk assessment in myelofibrosis patients better than current models

2025-03-27

(WASHINGTON—March 27, 2025) — A machine learning model generated by a team from the European Society for Blood and Marrow Transplantation (EBMT) outperformed standard statistical models in identifying and stratifying transplant risk for patients with myelofibrosis, according to new research published today in Blood, the American Society of Hematology’s flagship journal. “Although there are many models available to identify patients with high-risk myelofibrosis, we are still lacking ...

Beyond ambiguous reflections: Bridging optical 3D metrology and computer vision

2025-03-27

Accurate and robust 3D imaging of specular, or mirror-like, surfaces is crucial in fields such as industrial inspection, medical imaging, virtual reality and cultural heritage preservation. Yet anyone who has visited a house of mirrors at an amusement park knows how difficult it is to judge the shape and distance of reflective objects. This challenge also persists in science and engineering, where the accurate 3D imaging of specular surfaces has long been a focus in both optical metrology and computer vision research. While specialized techniques ...

AI is as good as pathologists at diagnosing celiac disease, study finds

2025-03-27

A machine learning algorithm developed by Cambridge scientists was able to correctly identify in 97 cases out of 100 whether or not an individual had coeliac disease based on their biopsy, new research has shown. The AI tool, which has been trained on almost 3,400 scanned biopsies from four NHS hospitals, could speed up diagnosis of the condition and take pressure off stretched healthcare resources, as well as improving diagnosis in developing nations, where shortages of pathologists are severe. Digital ...

AI could help sonographers identify abnormalities in unborn babies more quickly

2025-03-27

Artificial intelligence (AI) could help sonographers identify any abnormalities at the 20-week pregnancy screening scan almost twice as quickly, without reducing the accuracy or reliability of diagnoses, a new study has shown. This will help improve patient care by allowing sonographers to focus on other aspects of the scan, such as communicating with parents or spending more time looking at any areas of concern. The trial is the first of its kind to use AI for the 20-week pregnancy scan on real patients, and is ...
