The Pew Charitable Trusts awarded Dr. Karla Meza-Sosa the 2015 Pew Latin American Fellowships in the Biomedical Sciences 

As a Pew fellow Dr. Meza-Sosa will study the molecular mechanisms by which a long-non coding RNA mediates the cellular response to genotoxic stress. This research will shed new light into the molecular mechanisms that determine cell fate outcome (apoptosis, cell cycle arrest or senescence), and provide new insight into the mechanisms underlying gene expression control exerted by lncRNAs.

Can breast cancer cells tell each other to metastasize?

By Tom Ulrich

Not all cancer cells are created equal. In fact, to call a cancer a cancer, in the singular, is something of a misnomer. Really, a patient could be said to have cancers, as every tumor is actually a mixture of cells with different mutations and capabilities. 

One of those capabilities is the ability to escape the main tumor and spread, or metastasize, to other sites in the body. Not every cancer cell has this ability. But just like bacteria can share the ability to resist antibiotics, at least some cancer cells may be able to share the ability to spread.
