Burrowing crabs reshaping salt marshes, with climate change to blame

Given higher sea levels and softer soil in the wake of a shifting climate, Sesarma crabs, which have already decimated salt marshes in the Northeast, are now rising to prominence in southeastern marshes, a new study finds.

Researchers demonstrate strange melting point phenomenon in metals

Quantum mechanical calculations show that the melting point of metals decreases at extreme pressure, meaning even high-density metals can have a liquid phase that’s actually denser than its normal solid phase.
