Memories are encoded by sparse populations of neurons but how such sparsity arises remains largely unknown. We found that a neuron’s eligibility to be recruited into the memory trace depends on its epigenetic state prior to encoding. Principal neurons in … Memories are encoded by sparse populations of neurons but how such sparsity arises remains largely…
Earthquakes vary in size over many orders of magnitude, often rupturing in complex multifault and multievent sequences. Despite the large number of observed earthquakes, the scaling of the earthquake energy budget remains enigmatic. We propose that … Earthquakes vary in size over many orders of magnitude, often rupturing in complex multifault and multievent sequences. Despite the…
Protein folding both promotes and constrains adaptive evolution. We uncover this surprising duality in the role of the protein-folding chaperone heat shock protein 90 (Hsp90) in maintaining the integrity of yeast metabolism amid proteotoxic stressors … Protein folding both promotes and constrains adaptive evolution. We uncover this surprising duality in the role of the protein-folding chaperone…
