Researchers develop system to test brain ultrasound treatments in mice

Noninvasive brain ultrasound treatment represents a promising alternative to other brain stimulation modalities and pharmaceutical drugs; however, testing it can be challenging due to a lack of preclinical systems for chronic stimulation in awake animals. As described in research published in Advanced Science, investigators recently developed a system to deliver ultrasound stimulation to the brain in awake, naturally behaving mice.

Researchers Uncover How Resistance to Treatment Can Develop in Breast Cancer Cells

A new study in mice by researchers at Baylor College of Medicine has investigated how breast cancer cells lose their estrogen receptor–positive (ER+) expression. Their findings reveal a mechanism that explains the process and potential possibilities to overcome it.
