Huntington's disease has long been framed as a protein problem: mutant huntingtin clumps inside neurons and kills them. A new Cell study maps 428,173 cortical cells and finds that the neurons most likely to die carry extreme somatic expansions of the CAG repeat, beyond 450 repeats.

A team at TU Wien and the University of California San Diego has now exceeded that limit in helium by timing two electrons to return together.
