FOXO factor promotes survival of oxygen-deprived cancer cells
Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen.   view more (2007-12-28)

Fight against hay fever and other allergies helped by new immune system discovery
A mechanism which can lead to hay fever and other allergic reactions, by preventing the immune system from regulating itself properly, has been discovered by scientists.   view more (2007-12-27)

CSHL scientists identify and repress breast cancer stem cells in mouse tissue
By manipulating highly specific gene-regulating molecules called microRNAs, scientists at Cold Spring Harbor Laboratory (CSHL) report that they have succeeded in singling out and repressing stem-like cells in mouse breast tissue - cells that are widely thought to give rise to cancer.   view more (2007-12-18)

The beauty of nature is partly due to the uniformity of leaf and flower size in individual plants, and scientists have discovered how plants arrive at these aesthetic proportions.   view more (2007-12-13)

MIT sorts cells with beams of light
Separating out particular kinds of cells from a sample could become faster, cheaper and easier thanks to a new system developed by MIT researchers that involves levitating the cells with light.   view more (2007-12-11)

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed
During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.   view more (2007-12-10)

Scientists discover new role for miRNA in leukemia
Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia (CML) from its more treatable chronic phase to a life-threatening phase, called blast crisis.   view more (2007-12-10)
