Molecular motor myosin VI moves 'hand over hand,' researchers say

... In the human body, hundreds of different types of biomolecular motors help carry out such essential tasks as muscle contraction, moving chromosomes during cell division, and reloading nerve cells so they can repeatedly fire. How these little proteins perform their duties is becoming clearer to scientists using a...

No longer just for biology, RNA can now be built into 3-D arrays

...overed that a bacteria-infecting virus possesses a biomolecular nanomotor that requires RNA molecules to function. While determining how RNA works in that motor, he learned to manipulate and control RNA assembly. Now, Guo and his colleagues have applied that knowledge to building artificial RNA nanostructures, ...

Carnegie Mellon U. develops microgel to recover enzymes for manufacturing, research assays

...aceutical agents. Armitage and Patterson relied on biomolecular recognition to create their microgel particles. For each particle, single DNA strands were used to create a three-way junction (TWJ) that looks like spokes of a wheel. To the end of each spoke, they tethered a strand of peptide nucleic acid (PNA), a ...
