A modeling study suggests that replacing universal hepatitis B vaccination at birth with delayed vaccination or a shared decision-making approach, as recommended by the U.S. federal government this year, could lead to substantially more chronic hepatitis B infections among U.S. children.

A new study in the IEEE Journal of Biomedical and Health Informatics reveals how scientists at Klick Labs created visual maps of sound frequencies (spectrograms) to identify complex, new patterns associated with type 2 diabetes, using only smartphone recordings of randomly selected short English sentences and participant sex as study criteria.

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a machine learning tool that can detect and estimate past radiation exposure using the information in a standard complete blood count, or CBC, one of the most routinely performed clinical blood tests.

One in five pediatric cancer patients in a large national cohort lived more than 90 minutes away from their treatment center, and patients with the highest social vulnerability were least likely to access out-of-state medical care, according to research presented at the 19th AACR Conference on The Science of Cancer Health Disparities, held Oct. 18–21, 2026.
