Preventing ‘Traffic Jams’ in Brain Cells

Imagine if you could open up your brain and look inside.

What you would see is a network of nerve cells called neurons, each with its own internal highway system for transporting essential materials between different parts of the cell. Read More →

Molecular Machines for Nanotech Applications

Two different assembly stages (purple and red) of the protein ubiquitin and the fluorescent probe used to visualize these stage (tryptophan: see yellow).

Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a study by University of Montreal researchers that was published in Nature Structural and Molecular Biology yesterday (cited below). The scientists have developed a new approach to visualize how proteins assemble, which may also significantly aid our understanding of diseases such as Alzheimer’s and Parkinson’s, which are caused by errors in assembly.
