Phys.org / Liquid-like histone H1 'glues' nucleosomes, reshaping how DNA compacts

DNA inside the nucleus is not packed as a rigid regular fiber—linker histone H1 dynamically binds and loosely "glues" nucleosomes together, creating a dynamic, fluid organization that can still support essential genome functions.

Phys.org / How an internal plant 'thermostat' guides root growth in unpredictable temperatures

Plants can't move to escape the heat like humans can; they are forced to adapt. As temperatures fluctuate, one key survival strategy is the ability of roots to keep growing, allowing plants to access water and nutrients farther ...
