01/25/12--21:00: Visual nudge improves accuracy of mammogram readings (chan 2523763)

(Washington University in St. Louis) False negatives and positives plague the reading of mammograms, limiting their usefulness. Cindy Grimm, a computer scientist at Washington University in St. Louis, and colleagues have shown the accuracy of novice readers can be improved by nudging them visually to follow the scanpath of an expert radiologist. The "nudge" is a brief change in the brightness or warmth in the image in the peripheral field of view.

(Queen's University) Researchers at Queen's University in Kingston, Canada have identified a possible cause for the loss of a tumor suppressor gene that can lead to the development of more aggressive forms of prostate cancer.


01/25/12--21:00: Mutated Kras spins a molecular loop that launches pancreatic cancer (chan 2523763)

(University of Texas M. D. Anderson Cancer Center) Scientists have connected two signature characteristics of pancreatic cancer, identifying a self-perpetuating "vicious cycle" of molecular activity and a new potential target for drugs to treat one of the most lethal forms of cancer.


01/25/12--21:00: Survival rates for pediatric bone marrow transplants top in nation (chan 2523763)

(University of California - San Francisco) The UCSF Benioff Children's Hospital has the best overall survival rates in the nation for bone marrow transplants, according to a recent independent review of 156 programs nationwide.

(American Society for Radiation Oncology) Head and neck cancers respond well to the anti-cancer drug erlotinib when it is administered before surgery and a stronger dose is given to patients who smoke, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium, sponsored by AHNS, ASCO, ASTRO and SNM.


01/25/12--21:00: Berkeley Lab researchers discover critical rotational motion in cells (chan 2523763)

(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab researchers have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, called "CAMo," for coherent angular motion, is necessary for the cells to form spheres. Otherwise, cells undergo random motion, leading to loss of structure and malignancy.
