Amount of breast water could be linked to the risk of breast cancer

A unique mother-daughter study that used magnetic resonance to measure breast density in younger women shows that percent of breast water could be linked to the risk of breast cancer in middle age and older.

Second look ultrasound: Effective MRI correlate for identifying incidental breast lesions

A second look ultrasound of the breast, used in conjunction with MRI, allows radiologists to identify lesions not detected on conventional mammography and first look ultrasound; in some cases it allows radiologists to determine whether or not a lesion is malignant or benign, according to a study performed at the University of Rome La Sapienza in Rome, Italy.

Researchers model 3D structures of proteins that control human clock

In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals.
