Origami with DNA

To study the behavior of T-cells, an unusual method was used: DNA molecules were folded in an ingenious way, similar to the paper folding art origami. In this way, not just a double helix is created, but a rectangular 'molecular raft' that floats across a cell membrane and serves as a tool for novel measurements.

Supersaturation: The barrier between protein folding and misfolding

It's commonly accepted that protein folding/misfolding are alternative reactions of unfolded proteins but the principles governing this remain unknown. Here, researchers describe a general concept that links protein folding and misfolding: protein folding and amyloid formation are separated by the supersaturation barrier of a denatured protein. Breakdown of this supersaturation barrier is required to shift the protein to the amyloid pathway, linking Anfinsen's intramolecular folding universe with the 'outer' intermolecular misfolding universe.

Solving complex physics problems at lightning speed

A calculation so complex that it takes twenty years to complete on a powerful desktop computer can now be done in one hour on a regular laptop. Physicists have now designed a new method to calculate the properties of atomic nuclei incredibly quickly.
