Researchers at Brown University have created an implant that appears to deter breast cancer cell regrowth. Made from a common federally approved polymer, the implant is the first to be modified at the nanoscale in a way that causes a reduction in the blood-vessel architecture that breast cancer tumors depend upon, while also attracting healthy breast cells. Results are published in Nanotechnology.

PROVIDENCE, R.I. [Brown University] — One in eight women in the United States will develop breast cancer. Of those, many will undergo surgery to remove the tumor and will require some kind of breast reconstruction afterward, often involving implants. Cancer is an elusive target, though, and malignant cells return for as many as one-fifth of women originally diagnosed, according to the American Cancer Society. (more…)

How do children come to realize that they themselves might be targets of prejudice? It may depend on their age. New research conducted at the University of Toronto shows that a six-year-old may be influenced most by direct instruction about prejudice, but once that child gets closer to 10, she begins to rely more on her own experiences.

“Young children are information hungry – they are eagerly searching for general rules to help in mapping out their social worlds,” write researchers Sonia Kang, an assistant professor in the Department of Management at U of T Mississauga and the Rotman School of Management, and Professor Michael Inzlicht of the Department of Psychology in this month’s Personality and Social Psychology Bulletin.
