Posted: 27 Jan 2013 10:42 AM PST

The spread of breast cancer to distant organs within the body, an event that often leads to death, appears in many cases to involve the loss of a key protein, according to researchers, whose new discoveries point to possible targets for therapy.

Poor sleep in old age prevents the brain from storing memories

Posted: 27 Jan 2013 10:42 AM PST

But for the first time, scientists have found a link between these hallmark maladies of old age. Their discovery opens the door to boosting the quality of sleep in elderly people to improve memory.

Patients' own skin cells are transformed into heart cells to create 'disease in a dish'

Posted: 27 Jan 2013 10:42 AM PST

Researchers have unveiled the first maturation-based "disease in a dish" model for arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). The model was created using induced pluripotent stem cells and a new method to mimic metabolic maturity. This model is likely more relevant to human ARVD/C than other models and therefore better suited for studying the disease and testing new treatments.

Organizing human specimen collections: Getting the best out of biobanks
