New prognostic marker for breast cancerElevated levels of GLI1 (glioma-associated oncogene homolog 1) protein in human breast cancer are linked to unfavorable prognosis and progressive stages of disease. Scientists writing in the open access journal BMC Cancer found increased expression of GLI1 in samples taken from more advanced and less survivable tumors.

Evolution of the appendixThe lowly appendix, long-regarded as a useless evolutionary artifact, won newfound respect two years ago when scientists at Duke University Medical Center proposed that it actually serves a critical function.
