Breast cancer cells recycle ammonia, a waste byproduct of cell metabolism, and use it as a source of nitrogen to fuel tumor growth, report scientists from Harvard Medical School. The insights shed light on the biological role of ammonia in cancer and may inform the design of new therapeutic strategies to slow tumor growth.

A University of Colorado Cancer Center study published today in the journal ACS Nano describes the use of cutting-edge microscopy technology to visualize how liposomes escape from blood vessels into surrounding cells in a living mouse, offering clues that may help researchers design better drug delivery systems.

Many adults put off discussing end-of-life issues with children, but a UB researcher says the otherwise difficult conversation can begin with the help of Disney/Pixar films.

Modeling the interplay between neurons and astrocytes derived from children with Autism Spectrum Disorder (ASD), researchers at University of California San Diego School of Medicine, with colleagues in Brazil, say innate inflammation in the latter appears to contribute to neuronal dysfunction in at least some forms of the disease.

Children who are considered to be at risk of developing eye cancer should receive genetic counseling and testing as soon as possible to clarify risk for the disease. This is the consensus of leading ophthalmologists, pathologists and geneticists, who worked for two years to develop the first U.S. guidelines on how to screen for the most common eye tumor affecting children.

Two Medicare 'pay for performance' programs have contributed to declining financial performance by hospitals in the Mississippi Delta region, suggests a study in the November issue of Medical Care, published by Wolters Kluwer.
