Biocompatible liquid ink enables scalp-printed electrodes for non-invasive EEG

For the first time, scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology, presented December 2 in the Cell Press journal Cell Biomaterials, offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.

Lung cancer screening with CT can identify coronary artery calcium

Lung cancer screening with low-dose chest computed tomography (CT) may detect more than just lung cancer. As new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231602 shows, these CTs can identify coronary artery calcium, a strong risk factor for coronary artery disease (CAD), in patients without cardiac symptoms.
