In our experiments, only nanowires - which we know now to contain a single d...

Scientists to make news at Computational Biology Conference

... accomplishments will dot the landscape at a giant assembly of computational biologists in Vienna in mid-July. From new ways to discern how DNA folds into cell nuclei to possible treatments for diseases such as cancer, both basic and applied biology are getting a boost from researchers who call themselves bio...

Penn researchers discover how microRNAs control protein synthesis

...e manufacturing of proteins to begin. However, the assembly of proteins quickly comes to a standstill when the miRNA-Ago2 complex binds near the back end of a messenger RNA. By analyzing the amino acid sequence of Ago2, Kiriakidou and others uncovered a similarity with the cap-binding domain of the EIF4E prot...

Their rapid assembly and disassembly helps transport proteins throughout the cell and generate polarized (directional) signal distribution that causes cells to move. While microtubules in some specialized cells can originate from non-centrosomal structures, the centro...
