Phys.org / Oxygen sensing helps explain why amphibians regenerate limbs but mammals cannot

Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why. Now a team led by Can Aztekin at EPFL ...

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 ...

Phys.org / From Asgard to Earth: Tiny tubes may reveal the moment complex life began

Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...
