Penn researchers find role for microRNAs in angiogenesis

..., which indeed turned out to be a microRNA cluster designated miR-17-92. In the key experiment the researchers engineered poorly angiogenic tumor cells to produce copious amounts of miR-17-92. These modified cells, just like cells with hyperactive MYC from earlier experiments, formed much larger tumors with b...

Global coral reef assessment built on NASA images

Countries around the world have created these protected ocean and coastal zones where human activities such as shipping, fishing, recreation and scientific ...

Making a face: A new and earlier marker of neural crest development

...is work that neural crest stem cell precursors are designated very early in development -- as early as the gastrula stages -- and in an independent fashion from those other tissues," said Martn Garca-Castro .
