Acoustic battles for the harem: How the calls of Siberian wapiti reveal their status and individuality

Researchers found that rutting calls of Siberian wapiti stags reflect their harem-holding status and individual characteristics. The study suggests that these acoustic displays enable females to assess a male's quality from a distance, while also signaling to rivals whether it's worth challenging him.

Revolutionizing bone regeneration: functionalized flat silkworm cocoon scaffolds with magnesium ions

Long-term exposure to air pollution linked to blood clots in veins that bring blood to the heart

A large US study found a strong association between long-term air pollution exposure and an increased risk of blood clots in deep veins, also known as venous thromboembolism. Participants with higher exposure to particulate matter, oxides of nitrogen, and nitrogen dioxide had a significantly increased risk of developing these conditions.

Artificial intelligence improves mammography-based risk prediction

Artificial intelligence is enhancing breast cancer risk prediction through mammographic analysis, uncovering key features that predict breast cancer risk. These AI-generated features may inform personalized screening strategies, such as more frequent or less frequent screenings for women at high or low risk of breast cancer.
