Recent advance in detonation theory

Researchers Hu et al. developed a new detonation model named the least-action detonation model (LADM) that takes into account complex movement and transport effects, differing from the classical ZND model. The LADM model predicts detonation product particles to be in a stationary state, which has been observed in experiments.

CSHL team solves a protein complex's molecular structure to explain its role in gene silencing

Researchers from CSHL and St. Jude's Research Hospital have discovered new details of how a protein complex contributes to heterochromatin assembly and gene silencing in fission yeast. The team identified a previously unknown substructure at the end of Chp1, which plays a crucial role in heterochromatin formation at telomeres.
