Study identifies RNA molecule that shields breast cancer stem cells from immune system

Researchers from Princeton University’s Department of Molecular Biology have identified a small RNA molecule that helps maintain the activity of stem cells in both healthy and cancerous breast tissue. The study, which will be published in the June issue of Nature Cell Biology, suggests that this "microRNA" promotes particularly deadly forms of breast cancer and that inhibiting the effects of this molecule could improve the efficacy of existing breast cancer therapies.

Nitrogen contained in coral provides evidence of human impact on the open ocean

New evidence suggests that a nutrient that is both essential to life and an environmental scourge when present in large quantities is increasing in the open ocean, according to a new study published May 19 in the journal Science. The increase of this nutrient, known as "fixed" nitrogen, was studied in coral. The findings give researchers new insight into ocean ecosystems, which in turn provides a greater understanding for scientists and policymakers on how they should prioritize human-made threats to Earth's biosphere and climate.
