Researchers have developed a laser-assisted method that rapidly detects tiny amounts of CEACAM-5, a colorectal cancer biomarker, in blood. The technique enhances antibody–antigen interactions and achieves detection even at low concentrations within minutes. The researchers also identified nanoscale CEACAM-5 aggregates that may enhance the method’s sensitivity.

Researchers from the Japan Advanced Institute of Science and Technology, Japan, assessed the ethics of large language model-generated advice for modifying built environments to support health. In the first study of its kind, researchers evaluated 180 ChatGPT responses across six health pathways, neighborhood income contexts, and budget conditions using four ethical criteria. ChatGPT consistently avoided harmful recommendations and rarely gave lower-income neighborhoods weaker proposals, but showed less consistent community participation and oversight, particularly under constraints.

A world-first test developed by researchers at the Garvan Institute of Medical Research has identified the genetic cause of inherited muscle disease in people who remained without answers after years, sometimes decades, of standard testing.

ARPA-H funds UC Davis up to $36.5M to research how to help living cell therapies withstand room temperature storage and shipping so they can help more people, more cheaply.

WashU Medicine researchers found that dozens of blood proteins shift during Alzheimer’s treatment and may help monitor the effects of the medication.
