Cells have evolved to regulate the asymmetric distribution of specific mRNA targets to institute spatial and temporal control over gene expression. Over the last few decades, evidence has mounted as to the importance of localization elements in the mRNA sequence and their respective RNA-binding proteins. Live imaging methodologies have shown mechanistic details of this phenomenon. In this minir...

Colloidal inclusions in lab-on-a-chip devices can be used to perform analytic operations in a non-invasive fashion. We demonstrate here a novel approach to realize fast and reversible micro-sieving operations by manipulating and transporting colloidal chains via mobile domain walls in a magnetic structured substrate. We show that this technique allows one to precisely move and sieve non-magneti...

Since 2010, Tony Huang, Ph.D., from the Acoustofluidics laboratory at Penn State University in University Park, Penn.; Ming Dao, Ph.D., from the Massachusetts Institute of Technology in Cambridge; and Subra Suresh, Ph.D., now president of Carnegie Mellon University in Pittsburgh, came up with the idea of using sound waves to tweeze out pathological cells from normal blood cells. Four years late...
