Breast cancer patients and their physicians may make more informed, long-term treatment decisions using risk assessment strategies to help determine probability of recurrence, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Aug. 12 online issue of the Journal of the National Cancer Institute.

The American Physical Therapy Association concurs with findings from a recent study published in Spine (Vol. 33, No. 16) demonstrating that active physical therapy for patients with acute low back pain is associated with better clinical outcomes, decreased use of prescription medications, MRI and epidural injections, and lower health-care costs than passive physical therapy.

Medulloblastomas are common and aggressive brain tumors that occur mostly in children and teenagers. In two studies, working together with international scientific teams, Ludwig-Maximilians-Universität München medical scientist Dr. Ulrich Schüller has now successfully revealed the type of cell from which these tumors arise — which could lead us to more targeted and thus better therapies for these cerebellar tumors.

Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: How is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks? A team of researchers, led by the University of Bristol, working alongside colleagues at the STFC Daresbury Laboratory, have gained a deeper insight into how the Earth recycles itself in the deep earth tectonic cycle way beyond the depths that can be accessed by drilling.

Are working women treated more fairly in today’s labor market than they were 30 years ago? Absolutely not, according to groundbreaking new research by Brown University economist Yona Rubinstein and Casey Mulligan of the University of Chicago. Disputing decades of economic literature, the economists show that the apparent narrowing of the wage gap between working men and women is actually due to the type of women who are now working — not how much they’re being paid.
