Atom probe tomography reveals fluoride patterns in aging teeth

Teeth are essential for helping people break down the food they eat and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repair damage, which means that as we age, it risks becoming weaker with time.

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.
