...gaster) from a single cell to an adult. A computer algorithm written by the researchers scanned nearly 3,000 genes. Statistical techniques were then used to investigate whether particular transcription factors correlated with genes that were differentially expressed (turned on or off) between nurse bees and fo...Tissue geometry plays crucial role in breast cell invasion
...dimensional micropatterned assay. Using a special algorithm to quantify the extent of branching, the researchers found that the geometric shape of the tubules determines where branching takes place. This may potentially affect where and how a malignancy spreads. The paper is entitled: Tissue Geometry Determ...16 outstanding researchers receive Singapore's highest honor in science and technology
