Mimicking nature’s twist: time-evolving helicity in a polymer

A team of scientists developed a chlorophyll-based supramolecular polymer that can gradually evolve from nonhelical fibers into well-defined helical structures. The transformation occurs cooperatively and is driven by small energy differences between stable arrangements, offering a blueprint for designing dynamic helical structures.

Mirror-image peptides form ‘rippled sheet’ structure predicted in 1953

A team of researchers at UC Santa Cruz has created an unusual protein structure known as a ‘rippled beta sheet’ by mixing mirror-image peptides. The study used x-ray crystallography to obtain images of the structure, which closely matches predictions made in 1953 by Linus Pauling and Robert Corey.

Researchers decipher modus operandi of potential Alzheimer's drug

Researchers have discovered how methylene blue modifies tau proteins, which aggregate in Alzheimer's disease. The study reveals that methylene blue deactivates molecular residues promoting bonding and acts as a spacer to keep proteins apart, leading to potential treatment strategies.
