Researchers integrated several approaches, such as cryogenic 3D imaging at the ALS, to define a novel cellular pathway—involving a shared “garbage dump”—for clearing misfolded proteins from cells. The pathway is a potential therapy target for age-related diseases like Alzheimer’s, Huntington’s, and Parkinson’s diseases. Read more »
Coaxing Molecules to Stand Tall for Better Solar Cells

Chiral Twists and Turns Lead Way to New Materials
Researchers found that, in crystals with structural chirality (left- or right-handedness), tuning the electronic behavior reveals hidden chiral phases and singularities. The results provide a new way to predict, test, and manipulate novel materials that exhibit desirable properties for next-generation electronic and spintronic devices. Read more »
