Fault size–dependent fracture energy explains multiscale seismicity and cascading earthquakes | Science
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 ...

Selection for robust metabolism in domesticated yeasts is driven by adaptation to Hsp90 stress | Science
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 ...

Chromatin plasticity predetermines neuronal eligibility for memory trace formation | Science
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 ...
