  • The existence (or not) of electronic coherence in homopolymers is dependent on a balance between monomer–monomer interactions and environmental heterogeneity. Now, by understanding how even–odd orbital symmetry influences coherence and produces resistance oscillations as a function of distance—it is shown that DNA sequences can be designed to support coherent charge transport.

  • Despite being a paradigmatic description of dissipative quantum dynamics, implementations of spin-boson models with trapped ions had limited tunability. Here, the authors demonstrate a trapped-ion quantum simulator of spin-boson dynamics with controllable bath spectral density, contributing towards scalable simulations of energy transfer processes.

  • Charge transfer through DNA has been well studied over recent decades from both a biological and electronics perspective. It has now been shown that charge transfer can be accelerated one hundredfold by using highly energetic 'hot holes', revealing a new mechanism that could help to create useful electronic biomaterials.

  • The first demonstration of a protein designed entirely from first principles that binds a small-molecule cofactor in a precisely predetermined orientation has now been described. The design method utilizes a remote protein core that both anchors and predisposes a flexible binding site for the desired cofactor-binding geometry.
